Engineering K, Major professW Date 7/25I/7O / / 0-169 ABSTRACT A SYSTEMS ANALYSIS OF SUMMER ENVIRONMENT FOR LAYING HENS BY Richard Earl Phillips The objective of this study was to apply the systems approach to the analysis of summer environment for laying hens and to develop a simulation model which could be used in the study of parameters affecting the environment. The system was defined as the environment surrounding the laying bird and enclosed by the inner surfaces of the containing structure. A mathematical model was then developed to predict system temperature and humidity as a function of heat and mass transfer rates across system boundaries at discreet time points located at half hour intervals throughout the day. Items evaluated by the model included bird heat production, heat transfer through struc— tural components, electrical heat production, and heat and moisture exchange with ventilating air. Evaporation of free moisture from the manure surface was evaluated using a routine based on the Reynolds analogy for mass transfer in turbulent flow over a flat plate. Richard Earl Phillips Model performance was verified in a series of 22 one- day tests in a research caged laying house located at the Michigan State University Poultry Science Research and Teaching Center. Mean deviations between actual and pre- dicted system conditions over the 22 runs were 1.9 degrees F for temperature and 5.1 percent for relative humitity. Deviations were largely attributable to two factors. First, the model used two discreet functions for night and day bird heat production without transitional values. Second, the model responded instantaneously to rapid changes in interior or exterior conditions while actual system response appeared to be buffered by structural or physiological effects. A significant finding during these tests was that the floor slab, largely ignored in previous research and analysis, plays a major role in the determination of system conditions. Simulation studies were made using a hypothetical commercial sized production unit to evaluate the effects of different ventilation and management practices on system performance. Items investigated included ventilation rates, housing density, phase shifting between artificial and natural day periods, and a logic based ventilation control system. Conclusions from these studies included the following: 1. Ventilation rates in excess of 4.5 cfm/bird (l cfm/lb of body weight) do not significantly reduce peak temperatures in the system. Higher Richard Earl Phillips ventilation rates can increase daily temperature range by lowering minimum temperatures experienced during night time hours. Housing densities between .7 and 1.7 square feet per bird did not have a significant effect on the diurnal temperature cycle of the system when using an occupancy based ventilation rate. Changing the phase relationship between artificial and natural day can moderate system temperature extremes; however, this is done at the expense of reducing the daily range. The logic based control system using differential temperature sensing as a basis for ventilation rate regulation provides a means of increasing daily temperature range and reducing operating costs.

INTRODUCTION Maximum efficiency in egg production is achieved in an environment which provides ambient temperature in the range of 55-60 degrees F (Longhouse g£_gl,, 1960). The currently popular windowless housing structure is able to contain this desired environment during winter months through a combination of thermal barriers to reduce sensible heat losses and temperature regulated mechanical ventila- tion systems which serve the dual purpose of introducing fresh air and removing excess water. During summer months, outside temperature frequently exceeds the desired range and increased ventilation is not able to provide Optimum conditions for most efficient production. Traditionally, the design of environmental control systems for poultry structures has involved assignment of desired interior conditions, arbitrary selection of maxi- mum, minimum, or mean exterior design conditions, and the application of classical steady state heat and mass trans- fer relationships to establish a thermal and moisture balance. The number of calculations involved has in most cases limited the designer to only a few possible combi- nations of building design factors and management systems. During winter months, when interior conditions can be held at desired levels through varying ventilation rates, the steady state analysis has provided a useful tool for environmental design. As an aid to designing for summer conditions, it has two major deficiencies: first” the thermal capacitance of the structural components tend to exert a moderating influence on environmental extremes and to both delay and prolong their effect on interior environment. The effect of this thermal capacitance on air conditioning loads was studied by Livermore (1943). Leopold (1948) developed a hydraulic analogue for solu- tion of heat storage problems in air conditioned struc- tures and indicated that cooling of components is due largely to convective heat transfer and occurs at a slower rate than heating where radiant transfer is pre- dominant. The second major problem in steady state analysis during summer is the fact that bird heat production is temperature dependent. Ota and McNally (1961) in calorimter studies found that, although heat production is relatively constant in the thermoneutral range, there is a decrease in sensible heat and an increase in latent heat production with increases in ambient temperature above this range. Esmay §E_al., (1966) used the data of Ota and McNally in a study of the psychrometrics of air exchange in commercial egg production units during hot summer days and noted increased levels of latent heat production at higher outside temperatures. Reece and Deaton (1969) studied sensible and latent heat production of growing birds on a whole house basis and discovered important diurnal varia- tions in sensible heat removal from the structure which they attributed to 1) reduced bird heat production at high ambient temperatures, 2) use of floor and litter as a temporary heat sink during hot periods, and 3) use of sensible heat to evaporate free moisture in the structure during periods of lowered outside relative humidity. It was also suggested that sensible heat alone is not a sat- isfactory predictor of maximum interior temperatures. It is apparent that steady state techniques are not completely satisfactory in the analysis of structural environment under diurnally varying conditions. This is particularly true during summer months when conventionally used control systems are not able to eliminate large variations in internal conditions. Jordan and Barwick (1965) developed an electrical analog model to study farm building construction and ventilation effects. They reported that the model provides a more meaningful pre- diction of building response than steady state calcula- tions do. The role of the floor slab as a temporary heat sink was not, however, fully developed in the model and constant heat production within the structure was assumed. Stewart (1969) pointed out some of the deficiencies in present environmental design analysis methods and suggested the application of the systems approach to the study of environment. He also listed some of the para- meters he felt will be of importance in future design work. This research project was directed towards the appli- cations of the systems approach to the analysis of tempera- ture and moisture conditions inside a closed egg production structure during summer months. A mathematical model was developed to predict interior temperatures and relative humidities throughout the day as a function of external environment, type of construction, and management prac- tices. Field studies were conducted to verify model per— formance. Simulation runs were made using a digital com- puter to investigate effects of variations in management and environmental control practices on internal environ- ment. 2. MODEL DEVELOPMENT 2.1 System Definition and General Hypothesis Stewart (1969) defined a system as "a recognizable entity which accomplishes a process." A system is made up of physical and/or biological parts encompassed by some definable boundaries across which system inputs and responses can be viewed and analyzed. The system defined by this research is the environ- ment surrounding the laying hen and enclosed by the interior surfaces of the housing unit which contains her. Inputs to the system considered to be of importance in this study were heat and moisture. Outputs were changes in system temperature and relative humidity. The system was dynamic and digital computer techni- ques require discreet time points for analysis. It was therefore decided to View the environment at half-hour intervals throughout the day. The assumption was made that there was no net heat flow across the system boundry at these discreet time points. Net heat flow was defined as follows: Q _ _ net — O — Qb + Qe + Qw + Qc + Qf + Qv where: Qnet = net heat flow across system boundries Qb = heat added to system by birds Qe = heat added by electrical usage in the building Qw = heat flow through building walls QC = heat flow through ceiling Qf = heat flow through floor Q = heat removed by ventilation system If we define occupancy, management practices, con- struction, and exterior conditions, all of the independent variables except electrical heat in the above equation become functions of system temperature. It is then possi- ble to use approximation techniques to solve for system temperature. Newton's method of successive approximations was used in the model to converge on a temperature. This method is mathematically represented as f(t ) tn+1 = tn ' swip- where: tn+1 = new approximation to the solution tn = previous approximation value f(tn) = net heat flow across system boundries at temperature tn f'(tn) = first derivitive of f(tn) which was determined by the following central finite difference approximation (f(tn+ - f(tn-.l)) .2 l . _ .1 f (tn) - Additional assumptions inherent in the model design are listed below: 1. Single storied windowless construction with concrete floor slab on grade; 2. Caged laying confinement system with manure dropping areas below the cages; 3. Mechanical ventilation system consisting of controlled exhaust fans and fresh air slot inlets; and 4. Solar radiation effects do not make signi- ficant contributions to wall heat exchange because of roof overhangs which shade the wall areas for a considerable portion of the day. 2.2 Generation of External Environmental Conditions Diurnal dry bulb temperature behavior can be closely approximated by a sinusoidal function with amplitude vary- ing equally about the daily mean temperature. Minimum daily temperature was expected at approximately 6:00 a.m. and maximum about 3:00 p.m. during July in Michigan. Con— sidering time as the number of half-hour periods elapsed since midnight, the following three equations were developed to generate dry-bulb temperature as a function of minimum daily temperature and expected range: for 12:30 a.m. to 6:00 a.m. . _ t . tdb(l) ‘ tmin+ §br(1 + cos ($§%—l§)H) for 6:30 a.m. to 3:00 p.m. (1-cos(i—§§33)H) tdb i) t . + r tdb( ‘ mln 2 for 3:00 p.m. to midnight tdei) = Emin+t§brI1 + cos (i—§539)R) where tdb(i) = dry-bulb temperature at time = i half hours after midnight (deg F) tmin = minimum temperature expected = daily average - gbr (deg F) tdbr = expected daily range in temperature (deg F) H = 3.14 All simulations were for July when the expected mean temperature for Lansing, Michigan was 72 degrees F and the daily range was 23 degrees F. The ASAE Yearbook (1970) indicated that the mean daily wet-bulb depression for the Lansing area was approx- imately 8 degrees F for the month of July. This mean depression was used in conjunction with the mean dry-bulb temperature to establish an assumed constant dew point temperature. Dew-point and dry-bulb temperatures were then used in a modified version of the PSYCRO subroutine des- cribed below to arrive at a spectrum of wet-bulb tempera- tures for the day. Brooker (1966) presented a series of mathematical equations which can be used to mathematically determine all the psychrometric properties of air, from any two known properties. These equations were developed into a subroutine called PSYCRO for use in the model. Given the values for wet and dry-bulb temperatures in degrees F, PSYCRO returns all the other properties of air required for subsequent calculations. Solar radiation effects were incorporated through development of a sol-air temperature spectrum for the day. Sol-air temperature is a fictitious ambient temperature used to represent the total effects of ambient temperature and solar radiation in the analysis of structural heat transfer problems. As proposed by Mackey and Wright (1944), Sol-air temperature is t... = t. + 21 c where: tsa = sol-air temperature (deg F) ta = dry bulb temperature (deg F) b = solar absorptivity of surface I = intensity of solar radiation (BTU/hour (Sq Ft)) fc = film coefficient of heat transfer (BTU/hour (Sq Ft) (deg F)) The major weakness in the sol-air temperature calcu- lation.as presented above is the fact that it makes no 10 attempt to account for surface radiation from the building to the sky or adjacent structures during night hours. This is not of serious consequence for commercial structures which have relatively small surface area per unit floor area; however, it should be considered in agricultural structures where the surface to floor area ratio usually exceeds 1.0. Parmelee and Aubele (1952) presented the following modification which provides a sol-air temperature that does consider night time emissions of radiant heat t'sa = [(aI — eAR)/(hco + h'r)] + tdb where t'sa = modified sol-air temperature (deg F) a = surface absorptivity e = surface emissivity AR = difference between black body radiation at ambient air temperature and radiation received by a horizontal surface hCO = outdoor surface convection coefficient (BTU/hour(Sq Ft)(deg F)) I = total incident solar radiation (BTU/hour (Sq Ft)) tdb = outdoor ambient air temperature h'r = surface radiation coefficient Incident solar radiation for a horizontal surface as a function of time in half hours after midnight can be dete mined by ll I(i) = (sinB(i)) (Ir(i)) where: I(i) = radiation on horizontal surface at time t = i half hours after midnight (BTU/hour (Sq Ft)) 8(i) = solar altitude angle at time t = i Ir(i) = total incident radiation on plane normal to sun at time t = i (BTU/hour Sq Ft) Total incident radiation on a plane normal to the sun as a function of solar altitude as given in the ASHRAE Guide (1963) is presented in Table 2.1. Solar altitude as a function of time in half hours after midnight for the month of July at latitude 42 degrees North is presented in Table 2.2 (Threlkeld, 1962). Using these values and the sol-air temperature modifications prOposed by Parmelee and Aubele (1952), the model uses the following series of equations to calculate sol-air temperatures for the 48 half-hour intervals dur- ing the day AR = otdba(i)4 (1 - .55 + .33 «FT'Tv 1) tsa(i) = [(aI(i) -sAR)/(hCO + h'r)] + tdba(i) Where: 0 = Stephan Boltzman constant (.173 x 10.8) s = a = .5 PV(i) = vapor pressure of air at time t = i (inches hg) 12 TABLE 2.l.--Tota1 incident solar radiation on a plane normal to the sun as a function of solar altitude.

Other terms as previously defined. 2.3 Bird Heat Production Total heat and moisture production of the chicken has been well documented in the research literature. Barott and Pringle (1941 and 1946) reported the results of calori- meter studies of metabolism levels in Rhode Island Red hens as a function of ambient temperature. They found that heat production remained relatively constant in the ambient temperature range of 65-80 degrees F. Above 80 degrees, total heat production increased, sensible heat decreased, and latent heat increased. Diurnal variations in metabolic rate were observed. These variations were in phase with the natural day which the birds had been previously exposed to. Ota and McNally (1961) conducted calorimeter studies with three breeds of laying birds at different ambient temperatures. During the night-time hours, sensible heat production declined about 17 percent as compared to daytime conditions. There was no significant difference in latent heat production between day and night. Data obtained with Single Comb White Leghorns are presented in Table 2.3. 14 TABLE 2.3.--Heat production at various levels of ambient temperature for S.C. White Leghorn hens.

The model was developed accordingly with the data of Table 2.3 being used in a linear interpolation routine called TABLI which was developed by Llewellyn (1965) for use in dynamic simulation programs. The selection of day and night levels of heat production is made on the basis of whether or not lights are on in the structure. 2.4 Electrical Heat Production Within the System Use of electricity for artificial lighting and to power materials handling equipment provides a direct source 0f sensible heat to the system. The amount of electrical 15 energy added during the hours of artificial daylight was estimated at 1 watt per square foot of floor area and the amount of heat added is Q = 3.413 A e where: Qe = rate of sensible heat addition to system by electrical usage (BTU/hour) 3.413 = BTU/watt hour A = floor area in square feet Electrical usage during "night" hours was assumed to be negligible and not to add any heat to the system. 2.5 Wall and Ceiling Heat Exchange Conventional steady state analysis of heat flow through structural components is based on the Fourier equation for heat conduction Q = -KAAt where: Q = rate of heat conduction (BTU/hour) K = thermal conductivity of the component ((BTU) (Unit thickness)/(hour)(deg F)) A = surface area normal to direction of heat flow (Sq Ft) At = temperature difference between inside and outside (deg F) When time varying boundry conditions are included, the equation governing one dimensional unsteady state heat 16 flow for materials with constant thermal properties becomes (Holman 1963) 2 K %;§.= pC %% where: 321* . ——§-= second partial derivitive of temperature with 3x respect to distance p = density of material (lbs/cu ft.) C = specific heat of material (BTU/lb(degF)) -§§ = first partial derivitive of temperature with respect to time K = previously defined Although numerical methods involving finite difference approximations are easily adaptable to solution of this equation for homogeneous materials, the non-homogeneous construction of most poultry house walls and ceilings introduces considerable complexity. Mackey and Wright (1944) developed a method of evalu— ating transient heat flows in homogeneous walls or roofs which they later (1946) extended to cover non-homogeneous construction. This method predicts interior surface temp- eratures as .606(tsa-ti) t - = t- + $1 1 L _E. .__cg__— tsi“ 51 + Ae [tsa(1 15 tsa] l7 where: tSi = mean interior surface temperature for the day .“i - - ' ' ='—.._?l tsi(l 15 — sol air temperature at time t l 15 -I% = harmonic lag time in hours A1+A2 . Ae= 2 = mean harmonic decrement factor for the first two harmonics. The values of A and o versus L/K and KpC for a given wall or roof section have been plotted by Mackey and Wright (1944) and a graphical solution is possible once these governing parameters have been evaluated. Interior surface temperature for a composite wall section is evaluated using the same technique with the exception that apparent values are developed for L/K and KpC.

Jordan and Barwick (1965) considered the floor as a heat storage area only, while Reece and Deaton (1969) offered temporary heat storage by the floor as an eaxplanation of variation in data without attempting to CIuantify it. Other researches have dismissed slab effects EiS negligible due to the insulating effect of litter. Approximately 25 percent of the concrete floor slab :in.the modern cage laying house is utilized for walkways and equipment placement and, as such, is exposed directly to the interior environment without the buffering effect of insulating coatings of manure. The differential equation 19 governing transient heat transfer presented in the pre- ceeding section is also applicable to the floor slab and similar solution techniques can be applied. However, it was felt that the relatively high conductivity values of concrete and the porous fill material located beneath the slab provided a situation which was ameniable to the more rapid lumped parameter method of analysis. Heat exchange with the uncovered portion of the floor was calculated as Qf = (1.65) (.25) A (tf - ti) where: Qf = heat transfer rate (BTU/hour) -l.65 = inside surface coefficient previously defined .25 = proportion of floor surface exposed to environment A = total floor area (Sq Ft) tf = surface temperature of floor (deg F) t. = environmental temperature adjacent to floor determined as the average of outside temp- erature and mean inside temperature to compensate for normal stratification expected (deg F)' Floor surface temperature was assigned an initial value equal to the mean outside temperature for the day plus 5 degrees. This value was approximately equal to the mean expected interior temperature for the day and was intended to eliminate long term storage effects. Subsequent 20 values were determined for each time interval by means of the following equation (t I = (t ) - of f new f old (C)(M)(.25)(A) where: (tf)new = slab temperature for next time period (deg F) (tf)Old = slab temperature for present time period (deg F) M = mass of one square foot of slab plus mass of sufficient fill below the slab to make up a total thickness of 10 inches. Four inches of concrete plus 6 inches of sand was assumed for all simulations. This yielded a mass of 120 lbs. per square foot of floor space. Other terms previously defined. 2.7 Ventilation and Evaporation The introduction of outside air into the system and its subsequent removal by the exhaust fan permits the exchange of both latent and sensible heat. Sensible heat added or removed from the system can be determined from the change in temperature and the mass of air per unit time being moved through the system vs db) 21 where: st = sensible heat removed from the system (BTU/hour) .24 = specific heat of air (BTU/1b. (deg F)) Ma = mass of ventilating air leaving building (lbs/hr) t.,tdb = previously defined Latent heat removal is somewhat more difficult to evaluate. Latent heat arises from two sources; vaporized moisture produced directly by the birds, and moisture evaporated from the wetted surfaces of manure beneath the cages. Latent heat produced by the birds is well documented as a function of ambient temperatures and it is common practice to assume that all of this moisture is removed by the ventilation air stream. Free moisture evaporation from other wetted surfaces has been estimated in several more or less arbitrary ways in the literature. Three of the more common methods are noted below with potential limita- tions of each: 1. Complete equilibrium where moisture is evaporated at the rate produced and the production rate is assumed constant over the 24 hour period. This is the method used by Phillips (1968) in his analysis of supplemental heat requirements for poultry brooding. The relatively high temperatures associated with brooding are conducive to a great deal of evaporation and lower bird density provides large surface area per unit volume of moisture. The method 22 does not appear to be well adapted to summer conditions in the laying house. 2. Assignment of a fixed proportion of free waterv production for removal by the ventilation system. Long— house gt_gl. (1960) suggest an approach of this type for winter ventilation calculations, noting that some portion of the moisture is removed with periodic cleaning opera- tions and thus unavailable for evaporation. The two major problems inherent in this approach for summer calculations are the fact that free water production is temperature dependent and the amount of moisture removed with the manure will depend upon the frequency of cleaning. 3. Assignment of a fixed relative humidity level for ventilation air leaving the structure. Saeed (1966) reported that during summer, ventilation air appears to be exhausted from the poultry house at relative humidity of .62-.72 irregardless of exterior conditions. He refers to this phenomenon as "humidity index" and characterizes it as a structural phenomenon. It appears somewhat question— able if this phenomenon would persist throughout the range of conditions which might be tested in a simulation model. In view of the limitations envisioned with these previously used and suggested methods, it was felt that moisture evaporation calculations based more on physical relationships within the systemeould be appropriate. The first assumption in the development was that all vaporized moisture from respiration would be removed by the 23 ventilation air. Mass transfer equations using the Rey- nolds analogy for mass transfer in turbulent flow over a flat plate were adapted to predict evaporation rates. The basic equations are as follows EVAP = hd(.75)(2)(A)(CO - CS) where: EVAP = evaporation rate (lbs HZO/hour) h = mass transfer coefficient (lbs HZO/hour unit difference in concentration) .75 = proportion of floor area covered with manure 2 = factor included to account for added surface area due to surface roughness A = surface area (Sq Ft) C = mass concentration in air outside boundry layer (lbs HZO/lb mixture) C = mass concentration in saturated air at sure face (lbs HZO/lb mixture) The mass transfer rate (hd) is determined by h = S 9 V d t a where: St = Stanton number pa = average density of air in the turbulent zone (lbs/cu ft) V' = mean velocity of air outside the boundry layer (ft/sec) 24 The Stanton number is a dimensionless parameter determined from the Colburn correlation equation (Dhanac, 1969) CF ST: 2 S .667 c where: SC = Schmidt number for air = .6 CF = skin friction coefficient .667,2 = constants The skin friction coefficient (CF) is in turn calcu- lated from the following equation for turbulent flow over a flat plate .288 CF = R 1/5 e where: 1/5,.288 = constants R = Reynolds number e The mean velocity of air outside the boundry layer was calculated by dividing the total ventilation rate by the longitudinal cross sectional area of the structure and then applying a factor of 3 to account for natural stream effects and obstructions of cages and other equipment. The resulting velocities agreed well with subsequent mea- surements using a hot wire anemometer and work by Lilleng (1969). All heat required for evaporation of free moisture ‘was assumed to be provided by the ventilating air stream. 25 The net heat exchange due to ventilation was the sum of the latent heat required to vaporize the evaporation water plus the sensible heat required to effect any temperature change in the air. One of the most sensitive parameters in this analysis is surface temperature of the manure which is used to determine water concentration at the assumed saturated condition. The model estimates surface temperature as the average of slab temperature and the air temperature above the slab as previously determined in the evaluation of heat exchange with the exposed slab area. 2.8 Computer Program Outline The model was programmed in Fortran IV language for Operation on the Control Data Corporation model 6500 come puter at the Michigan State University Computer Laboratory. A complete listing of the program as used in simulations is contained in Appendix A and a brief description of its operation follows below. The program first reads in data values for outside conditions. Included are average daily temperature, range, wet bulb depression, solar altitude angles, and incident radiation. Values are then read for start of artificial day, thermal values for the structure, structure size and housing density. The first major execution section of the program generates outside temperature, relative humidity, and sol-air temperature spectrums for the 48 half-hour time 26 interval node points. These generated data are then printed out on the line printer. An array of zeros and ones is then generated to represent the times when lights are either off or on. This array is subsequently used in determination of electric heat and bird heat production levels. It could also be used to trigger any "day" or "night" related management practice. The program then enters the control loop which steps it through the 48 time points for the day. The first step in this loop is the initialization and updating of array location values to be used in subsequent steps. The pro- gram then assumes a system temperature equal to outside temperature plus 5 degrees and enters the Newtonian con- vergence routine. Subroutine HEAT, called from the con- vergence routine, determines net heat flow into the system as a function of given parameters by calling supporting subroutines designed to calculate heat flows through specific boundaries. Once the system conditions for a particular time point are determined, they are printed out along with the heat and moisture contributions across the various system boundaries. At the completion of the 48 time point day, control leaves the do loop and a printer plot of inside and outside temperatures for the 48 time periods is con- structed using subroutine PLOT. 3. MODEL VERIFICATION 3.1 Facilities and Equipment Verification studies were conducted in a 31' x 40’ pen contained in a 40' x 152' single story, clear-span poultry house located at the Michigan State University Poultry Science Research and Teaching Center, East Lansing, Michigan. The pen was separated from the adjacent pen on one side by a stud frame partition wall sheathed with a single thickness of 3/8" thick fir plywood. The opposite wall, separating the pen from a feed and utility room, was of stud frame construction sheathed both sides with 3/8" thick fir plywood and containing a 2-inch thickness of batt-type fiberglas insulation in the space between the studs. The two end walls of the pen were coincident with the sidewalls of the building and were constructed of an inner layer of 3/8" thick fir plywood, 3-inches of batt-type fiberglas insulation, and an outer surface of corrugated aluminum siding which was painted dark green in color. The ceiling was also covered with 3/8" fir plywood secured to furring strips attached to the lower chords of the roof trusses. There was a 6-inch thick 27 28 fiberglas batt insulation immediately above the ceiling and the roofing material consisted of natural finish corrugated aluminum secured to purlins attached to the upper chords of the roof trusses. Floor construction consisted of a flat surfaced concrete slab, 4 inches in thickness, laid over a 6-inch thick sand fill base. The general orientation of the building ridge line was North- west-Southeast with the 40 foot dimension of the pen being at right angles to this direction. The pen contained three rows of modified stair step cages which were suspended from the ceiling in the loca- tions shown in Figure 3.1. At the start of the testing period, the cages contained 647 Single Comb White Leghorn hens and 144 White Rock hens. Randomly selected samples of 20 White Leghorns and 10 White Rocks yielded average weights per bird of 4.4 lbs. and 6.5 lbs. respectively. Ventilation air was admitted to the pen through a continuous slot inlet located in the ceiling at the South— west wall of the pen. The inlet was designed to bring air over the top of the wall plate directly from outside. A baffle was used to direct the inlet air downward along the wall surface. Solid blocking between roof trusses, ceil- ing, and roofing material adjacent to the ceiling slot prev vented air from the attic space from entering the pen. Air was moved through the pen by a 24-inch diameter direct drive axial-flow exhaust type ventilating fan located in the center of the Northeast wall. Two different fans were used 0 1n {fir .11 3 2 N '14 o 15 50 04 Recorder o 12 o 13 m .—I Z- 8 5 $3. a: N a: 3;" 8 3» (U m (U U U G) (31 65 U U 30'4" j 16 9 4?: l. . . g o 8 Figure 3.l.--Floor plan of pen used in verification studies. 30 in this location during the course of the studies. The first was a constant speed 1/3 horsepower unit designed for thermostatic control. The second was a 1/4 horsepower unit equipped with an SCR (Silicon Controlled Rectifier) motor speed controller designed to utilize the temperature dependent resistance of a thermistor to automatically adjust fan speed in an attempt to maintain a preset interior temperature. In order to obtain the constant ventilation rates desired for the verification studies, the thermistor sensor was replaced with a precision wound 0-100 K ohm variable resistance unit which was adjusted to pro— vide the desired fan volumes. Copper-constantan thermocouples were installed in the pen area at the locations shown in Figure 3.1 and tab- ulated in Table 3.1. Two thermocouples were installed at each point and connected in parallel to provide an average temperature for the location. Thermocouple lead lengths and parallel connections were made in accordance with procedures described by Finch (1962). wet bulb tempera- tures were obtained by wrapping a gauze wick around a thermocouple and immersing one end of the wick in a supply of distilled water. The wick encased thermocouples were then oriented so that their maximum surface area was per— pendicular to the direction of the air stream. The gauze wicks were cleaned twice daily and replaced every three days or oftener if they had become uncleanable due to dust accumulation. 31 TABLE 3.l.--Thermocouple locations in test pen.

The recorder was equipped with a time clock which turned on the chart drive and cycling mechanism every 30 minutes. After a complete cycle through the 16 points, a micro switch assembly turned off the recorder until the time clock initiated the next sequence. 3.2 Experimental Procedure A total of seven different trials were made using five different ventilation rates and three different lighting schedules. Each trial was replicated on three consecutive days with the exception of the sixth trial which was replicated on four days due to weather conditions. A minimum conditioning period of two days was used between trials in which lighting schedule changes were made. A summary of the daily test conditions appears in Table 3.2. Birds in the pen were counted at the beginning of each trial period and the average weights obtained pre— viously were used in conjunction with the count to estab- lish a total bird weight for each trial period. The average weight did not vary from 4.8 lbs. per bird over the entire test period. Ventilation rate for a trial period was determined by use of a hot wire anemometer to measure air velocity over the face area of the fan discharge housing. This area was circular with a diameter of 25 inches and was divided into two concentric outer rings, each 4 inches 33 TABLE 3.2.--Summary of experimental runs.

Velocity readings were taken at one-inch radial intervals in each quadrant of each area in order to determine a mean velocity for the area. The mean velo- city for each area was then used to determine volume and volumes were summed over the three areas to get total ventilation rate. This rate was then divided by the num- ber of birds to obtain the net rate per bird. Ventilation rates for the seventh trial were varied between day and night by placing relay activated resist- ances in the SCR motor control circuit. The relay was placed in the lighting control circuit and wired so that it would activate the resistance associated with low volume delivery when the lights were on. When the lights were turned off, the relay placed the resistance associated with high volume delivery in the SCR circuit. Temperature data at the half hour interval recording points were entered on computer cards for analysis. The simulation program was modified to utilize actual outside conditions and initial floor slab temperature instead of generated data to predict system conditions at half-hour intervals. These predicted conditions were then printed out along with the actual conditions recorded during the test. Structural heat transfer values for the exterior walls and ceiling evaluated according to methods described in Chapter 2 were as follows: 35 walls: (Kpc)apparent = .099 L _ (K)apparent - l2°58 Xe = .035 ¢/15 = 3.5 hours ceiling: (KDC)apparent = .059 L _ (E)apparent _ 23°94 Ae = .012 ¢ _ 15 — 5 hours Heat flow through walls separating the pen from the adja- cent pen and from the feed room was assumed to be negligible and was not included in the data analysis simulation. A second computer program which utilized the recorded surface temperatures in a steady state approximation to actual heat flows was developed. Output from this program was used as a comparison for order of magnitude of heat flows through the various structural components as predicted by the simulation model. 3.3 Results and Discussion The model was an acceptable predictor of system con- ditions for all runs. Actual outside and inside tempera- tures, along with predicted inside temperatures for one run from each trial period are plotted in Figures 3.2 36 through 3.8. Data for all runs are tabulated in Appendix B. Mean deviation between actual and predicted tempera- tures for all runs was 1.9 degrees F. Mean deviation between actual and predicted relative humidities for all runs was 5.1 percent. Maximum deviations from predicted values occurred when exterior or interior conditions were changing rapidly. In these situations, the model tended to respond instantaneously while actual conditions were buffered by structural or physiological effects. These effects were particularly evident for the last series of trials (Figure 3.8) where ventilation rate was changed by a factor of 3 and the birds were switched from day to night simultaneously. Mean deviations between actual and predicted values for the three runs where this was done were 3.1 degrees F for temperature and .073 for relative humidity. This was in direct contrast to those runs conducted under conditions where ventilation was constant and outside temperature levels are nearly sinusoidal in behavior. An example of this was run 19 (Figure 3.7) where the mean deviations were 1.0 degrees F and .031 RH. Higher than actual temperature predictions were associated with low humidity predictions and vice versa. This tended to indicate that the surface temperature of manure, which has major influence on evaporation, was in fact responding more rapidly than the model predicted. 37 .w can now mmusuoquEmp opflmcw empowowum can :moflmcfl :mofimusoII.~.m musmah mafia m m m .2 NH m m m 1.3 mowmcfl copowpmum I 839: all: . . . . .. . :8 @2320 ll: . . . .. o Icom . . :2. .bm prmflz A. sea Em;— .. .ba (a Esp) exniexedmel .m can How mmusumuwmswu moans“ oouoflowum pom .oofiwcw .oofimusoII.m.m musmflm mafia m m m .2 NH m w m l u 0 IL I u u as woflmcfl concatenm ..om moflmsw u : wwflmudo all... 38 uscfiz >mo 1L .om .om (a 699) eanexedmel 39 .NH can Mom mmusuwummsop monCA owpoflpmum one .mpwmcfl .monDDOII.v.m onsmflm mafia m m m .2 NH m m m A u u u a u I» q :8 mpwmcfl pmuoatmum allblls wUflmCfl Qulblb tom mmeDSO Illd .I III [I _I 232 Rd 232 I— :2.

Two items could contribute to this observed phenomenon. First, this was a period of rapidly increasing outside temperature which could promote a more rapid increase in moisture evaporation than predicted. Second the model assumes instant assumption of a constant daytime metabolic rate when the lights are turned on in the struc- ture. Barott and Pringle (1946) reported that metabolic rate is cyclic and doesn't reach a maximum level until sometime after initiation of day. It then declines and reaches a minimum level approximately 12 hours later. The high level of insulation in the ceiling prevented the solar radiation effects from having any noticable effect on heat exchange in the system. Because of this, the model appeared to function equally well on both cloudy and clear days. Maximum interior temperatures on extremely hot days remained 5-7 degrees below outside temperatures during the warmest part of the day. The model correctly predicted this condition (Figure 3.4) and an analysis of component parts disclosed that the lower temperature was due to a combination of lower sensible heat production at the high ambient temperature, heat absorption by exposed areas of the cooler concrete floor slab, and increased evaporation 45 of moisture with its subsequent cooling effect. The heat sink effect of walls and ceiling was not a significant factor in contributing to the lowered interior temperature. The order of magnitude comparison of predicted heat flows with calculations using measured surface tempera- tures and conventional steady state relationships revealed no major discrepancies between actual and model predicted exchange rates. 4 . SIMULATION STUDIES 4.1 Values Common to All Studies One of the major assets of a simulation model such as the one developed in this study is its usefulness as a tool in the study of variations in the parameters which affect system behavior. This chapter presents the results of a study made of three such parameters and also of a prOposed ventilation control system which maximizes the effectiveness of exterior environmental conditions in reducing stresses induced by summer conditions. The structure chosen for use in these studies was a single storied, clear span, windowless unit with outside dimensions of 40' x 200'. Sidewall construction was assumed as outer and inner layers of 3/8" thick exterior grade plywood with a 3" thick layer of blanket type insu- lation between the two layers. Interior sheathing for the ceiling area was also assumed to be 3/8" plywood with a 3" thick batt insulation immediately above it. Roofing was .020" thick corrugated aluminum secured to roof purlins on tOp of trussed rafters. The floor was assumed to be 4" thick concrete slab placed over 6" of porous fill material. 46 47 Seventy five percent of the floor was occupied by manure storage. Evaluation of thermal properties for the composite wall and ceiling areas according to the previously cited Mackey and Wright method yielded the following values which were entered as data in the simulator. walls: (KDC)apparent = .095 L (K)apparent _ 13°05 Xe = .036 .51 _ 15 - 3.5 hours ceiling: (Kpc)apparent = .104 L (E) apparent — 12.58 Xe = .038 9 _ 15 — 4.0 hours Occupancy of the simulated structure was assumed to be Single Comb White Leghorn hens having an average weight of 4.5 lbs. each. During the course of the summer ventilation period, the system is subjected to a variety of external environ- mental conditions which are only generally represented by the average temperature conditions presented in Section 2.2. Maximum physiological stress on the bird is induced 48 by high system temperatures not usually associated with the normal outside temperature values for the Lansing area. In order to evaluate system performance over more of a range of exterior conditions, two different exterior temperature profiles were used in the simulation studies. The first was the normally expected July value of 72 degrees F mean temperature, daily range of 23 degrees, and average wet bulb depression of 8 degrees. The second was regarded as an extreme conditionauuiutilized values of 85 degrees, 30 degrees, and 12 degrees for mean, range, and wet bulb depression respectively. 4.2 Ventilation Rates Deep body temperature of the chicken is 107.5 degrees F (Esmay, 1969). When ambient temperature of the system surrounding the bird exceeds 90 degrees F, she is placed under high thermal stress and heat prostration is likely. If ambient temperature exceeds 100 degrees, Baker gt_al, (1958) state there is extreme danger of death. The principal means of temperature control in the more humid northern areas of the United States has been through ventilation. The inadequacy of conventional steady state heat flow equations to evaluate system temperature under summer conditions has led to the development of a considerable number of "recommended" ventilation rates and management control practices for ventilation systems. The first simulation study was directed towards the 49 determination of the effect of ventilation rate on system temperature. A total of six different constant ventilation rates were simulated for one day of operation at each of the two outside temperature profiles. Rates used were 2.5, 3.5, 4.5, 5.5, 6.5, and 7.5 cfm/bird (cubic feet per minute per bird). A housing density of .7 sq ft/bird and a 14—hour artificial day extending from 6:00 a.m. to 8:00 p.m. were used. A summary of simulation results is presented in Table 4.1 and temperature profiles for the 2.5, 3.5, 5.5, and 7.5 cfm/bird rates are plotted in Figures 4.1 and 4.2. The lowest ventilation rate produced the highest maximum, highest average, and minimum daily temperature range for both normal and extreme outside temperature conditions. Conversely, the highest ventilation rate produced minimum system temperatures and maximum daily ranges for both exterior temperature profiles. For normal exterior temperatures, system temperature at the 2.5 cfm/bird rate never went below exterior temp— erature. Increasing the ventilation rate from 2.5 to 7.5 cfm/bird decreased the daily maximum system temperature 5.5 degrees indicating that the heat required by increased evaporation was greater than that required to offset the sensible heat added by the higher ventilation rate. Of this 5.5 degree decrease, 3.3 degrees was obtained by increasing the ventilation rate to 4.5 cfm/bird.

Maximum system temperatures did not reach the 100 degree maximum of the extreme outside conditions with any of the ventilation rates tested. At the 2.5 cfm/bird level, maximum system temperature was 8.3 degrees below exterior temperature which reflected the decreased sensi- ble heat production, increased heat transfer to the floor, and higher evaporation rates associated with higher system temperature. Increasing the ventilation rate from 2.5 to 7.5 cfm/bird decreased the maximum system temperature only 2.1 degrees with 1.6 degrees of this decrease being asso- ciated with ventilation rate increase from 2.5 to 4.5 cfm/bird. The decreased effectiveness of higher ventila- tion rates under extreme outside conditions as compared to normal conditions is due to the fact that heat required for the higher evaporation rates associated with high ventilation is only slightly greater than the heat required to offset the increased addition of sensible heat by the ventilating air. The 5 cfm/bird increase in ventilation rate decreased the daily minimum temperature 6.3 degrees F with 4.4 degrees of this decrease being associated with the increase from 2.5 to 5.5 cfm/bird. The more rapid decrease in minimum temperature with increasing ventilae tion rates indicated that the higher rates were more effective in reducing system temperature during the night. 54 At this time, exterior temperatures were lower than system temperatures and ventilation air did not contain more sensible heat than system air. Increasing the ventilation rate tended to minimize the transitional effect between night and day which the model exhibits. This is to be expected since the effect is due to the assumed instantaneous change in sensible heat production and the increased air exchange at the higher ventilation rates dilutes the effect of the heat on system temperature. 4.3 Densitnyffects Housing density and its subsequent effect on exposure factor as defined by ASAE:D270 (ASAE Yearbook, 1970) is an important element in determining housing design and ventilation parameters for winter conditions. We might also expect density to have some effect on summer environ- ment since it directly affects total bird heat production, a major system input. This series of simulations was designed to investigate the density effect. A total of 12 one-day simulations were made using six different housing densitiesand the two outside temp- erature profiles. Densities used were .7, 19, 1.1, 1.3, 1.5, and 1.7 sq ft/bird (square feet per bird). A constant ventilation rate of 4.5 cfm/bird and an artificial day of 6:00 a.m. to 8:00 p.m. were used for all runs. Summarized results for the housing density simula— tions are presented in Table 4.2 and temperature profiles 55 TABLE 4.2.--Effect of housing density on system temperatures.

Maximum system temperature was decreased 1.1 degrees F when density was decreased from .7 to 1.7 sq ft/bird under normal outside temperature. Minimum temperature was decreased only .1 degree for the same density change. In the case of extreme outside temperature, the .7 to 1.7 sq ft/bird decrease in density reduced the maximum system temperatures 2.1 degrees F and minimum system temperatures .4 degrees F. Density effects were most noticable during the 11:00 a.m. to 6:00 p.m. period when outside temperatures are above the daily mean. System temperatures for a given outside temperature profile were essentially independent of density effects during the cooler portion of the out- side temperature cycle. 4.4 Variations in Artificial Day Ota and McNally (1961) reported a 17 percent increase in sensible heat production for daytime as compared to night hours. Usage of electricity for lights and materials handling equipment adds more heat during the daytime. The results of Section 4.2 indicate that the ventilation system is more efficient at heat removal during the night hours inhen environment outside the system is at its lowest temp— eeratures. Since the modern poultry house is windowless aand apparent day in the system is completely under control (3f the management of artificial lighting, the potential 59 exists for placing the period of maximum heat addition to the system in phase with the period when the ventilating air is best able to remove the unwanted heat. This parti- cular series of simulations tested this possibility. Ten simulated days of operation were run using the two outside temperature profiles and five different 14- hour artificial day periods. The "days" used were 6:00 a.m.- 8:00 p.m., 2:00 a.m.-4:00 p.m., 10:00 p.m.-12:00 noon, 6:00 p.m.-8:00 a.m., and 2:00 p.m.-4:00 a.m. A constant ventilation rate of 4.5 cfm/bird and a housing density of .7 sq ft/bird were used in all tests. Results for the ten runs are summarized and presented in Table 4.3 and system temperature profiles for two of the "days" are plotted in Figures 4.5 and 4.6. Under normal outside conditions, maximum system temp- eratures were minimized by placing the artificial day period at either 10:00 p.m.-12:00 noon or 6:00 p.m.- 8:00 a.m. Maximum temperature for these "days" was 78.4 degrees P which was a 3.2 degree decrease below maximums encountered with the other three day periods tested. Mini- mum temperature predicted for the two "days" was 65.6 which was equal to the highest minimum system temperature for all the day periods tested. Temperature range for the two days was 12.8 degrees; the lowest experienced for the five periods. Maximum daily range of 19.3 degrees occurred with the 2:00 p.m.-4:00 a.m. day period which had high and low system temperatures of 81.6 and 63.3 degrees F respectively. 60 TABLE 4.3.--Effect of different "days" on system temperatures.

The lowest system maximum of 89.6 degrees F was obtained with the 10:00 p.m.- 12:00 noon and 6:00 p.m.-8:00 a.m. "day" periods and the minimum daily range of 13.3 degrees was also obtained with these periods. The difference in maximum system tempera- tures for extreme outside conditions varied only .6 degree over the five day periods tested while the varia- tion for normal conditions was 3.2 degrees F; indicating that phase shifting is more effective in reducing maximum temperatures when outside conditions are normal. 4.5 Logic Based Ventilation Control System Squibb (1959) reported that New Hampshire hens are better able to withstand high average daily temperatures when these temperatures are associated with wide diurnal fluctuations. Similar results were also reported by Squibb et_§1. (1959) for white leghorn hens. Operating costs for a ventilating system are propor- tional to the amount of air moved. Supplying 4.5 cfm/bird for birds housed at .7 sq ft/bird in the simulated build- ing would require 6 one-half horsepower fans which at $ .02 per kilowatt hour would consume approximately $150.00 of electricity for a four-month summer period. Increasing the rate to 7.5 cfm/bird requires an additional four fans and increases operating costs by $100.00. Traditional farm operations are coincident with the period of natural daylight and even though most of the 64 equipment associated with egg production systems is auto— mated, an operator is still required. It is questionable if the small advantage shown for the temperature range of the 2:00 p.m.-4:00 a.m. "day" would either justify or influence changes to this operating schedule. A combination of Squibb's research, economics, and traditional operating patterns with the simulation results of the preceeding three sections permits the establishment of some management and ventilation control parameters which will improve temperature profiles for the system subjected to summer environment. These parameters would be as follows: 1. Artificial day period within the structure of 6:00 a.m.—8:00 p.m. 2. Maximum ventilation rates during the warm part of the day which do not exceed 4.5 cfm/bird or 1.0 cfm/ 1b of body weight. 3. Ventilation rates during the cooler part of the outside temperature cycle which will provide a lower system temperature and thus increase daily range. Control of this rate could be effected by an SCR fan controller circuit which adjusted fan delivery rate based on maximum temperature difference between outside and system condi— tions. A logic based control system which meets parameters 2 and 3 above and prevents system temperatures from dropping below the thermoneutral range was designed for the simulator. 65 A computer program flow chart which illustrates the func- tioning of this controller is shown in Figure 4.7. The controller possesses three levels of control; 1) it operates the ventilation system at a predetermined base rate of air exchange; 2) if system temperature drops below 55 degrees F, the controller reduces the ventila- tion rate until the desired minimum of 55 degrees is reached; 3) if system temperature is above 55 degrees F and it is more than 4 degrees above outside temperature, ventilation rate is increased to take advantage of the cooling possible with the lower outside temperature. Terminology used in Figure 4.7 is as follows: VENTR = ventilation rate (cfm/bird) T0 = outside temperature (deg F) TI = system temperature (deg F) BASE = base ventilation rate (cfm/bird) IND = indicator variable The controller was incorporated into the model and one day simulations were made using a base rate of 3.0 cfm/bird and the two outside temperature profiles. The desired 6:00 a.m.-8:00 p.m. day and a housing density of .7 sq ft/bird were used for both runs. System temperature and ventilation rates for the two days are presented in Figures 4.8 and 4.9. Ventilation rate for normal outside conditions ranged between the base rate of 3.0 cfm/bird and a maximum of 5.3 cfm/bird. Average rate for the day was 3.4 cfm/bird. 66 VENTR BASE IND = 0 L NEWTONIAN CONVERGENCE ROUTINE FOR SYSTEM TEMPERATURE PREDICTION I yes 61 .<_ 55> no VENTR = VENTR - .1 l TI-T034 no and IND = l IND # 1 yes t VENTR = VENTR + .1 ._____4 I EXIT FROM CONTROLLER Figure 4.7.--Flow chart for logic based ventilation control. 67 .mdhfipmummfiou monuso HmEHoc IIHouucoo GOHDMHHucm> comma OHmoH mchs wHHwoum wuspwuomfiou uoHuousHIl.m.e wusmHm wEHB m m m .2 NH m m m u n NI » u u h m w m w monpso l om msflmcs on om h ucmflz Jl NS 2E2 om (PITQ/WJD) uorqerrqueA (& Bap) eaneiedmam 68 LIEmummm COHumHHucw> omwmn OHmoH mchD wHHmoum onsumummfiwu HoHHoDCHII.m db mEHB .2 NH TIT Inrmsz opHmuso mesmcfl .mwusuonQEmu onmuso mEouuxm m 9 L'1I i IIIIII IIIIIIIIt urmflz A .v ousmHh (PITQ/WJD) notietfqueA (a Esp) exniexadmem 69 Maximum system temperature for the day was 83.8 degrees F; minimum was 64.5 degrees F; and the mean was 74.2 degrees F. The resulting temperature range for the day of 19.3 degrees was wider than that of any of the constant ventila— tion rates tested (Table 4.1). The ventilation rate remained at 3.0 cfm/bird except for the 3:00 a.m.-10:30 a.m. period, reflecting the fact that lower ventilation rates are required to maintain a given temperature differen- tial during the warm portion of the outside temperature cycle. This is due to a combination of lowered sensible heat production by the birds and an increased evaporation rate caused by lower moisture concentrations in outside air. Ventilation rate for the day also averaged 3.4 cfm/ bird for the extreme outside conditions with system temp- eratures ranging between 91.0 and 74.0. Mean system temperature for the day was 83.6. Ventilation rate exceeded the 3.0 cfm/bird base from 3:00 a.m.-9:30 a.m. which was one hour less than the period experienced with normal out— side conditions. The range of 17.0 degrees was comparable to that obtained with a constant ventilation rate of 4.5 cfm/bird for extreme conditions (Table 4.1). Operational costs for the logic based control system over a 4—month summer period using the previously developed figures would be approximately $115.00 or a reduction of 23 percent as compared to the 4.5 cfm/bird constant rate system. A comparison of performance with that predicted for the 4.5 cfm/bird rate indicated that both maximum and 70 minimum daily temperatures for the system were higher with the logic based control. Average daily temperatures, however, were lower which reflected the desirability of being able to increase ventilation rates during the cooler part of the day. Daily temperature range was equal or greater for the case of the logic based system. 5 . CONCLUSIONS The following conclusions are based on simulations and model verification studies conducted during this research project. 1. The simulation model developed in this study provides an effective tool for the study of structural and management factors influencing summer environment for laying hens. The floor slab, previously disregarded as an insignificant contributor to environment, plays a major role in the determination of interior temperatures and evaporation rates. Summer ventilation rates in excess of 4.5 cfm/bird (1.0 cfm/lb of body weight) will not significantly reduce interior temperatures during periods of extreme outside temperatures. Ventilation rates higher than 4.5 cfm/bird are effective in reducing the daily minimum system temperatures experienced during the night or cool period of the outside diurnal temperature cycle. However, rates in excess of 5.5 cfm/ 71 72 bird do not appear to be justified even for night time conditions. Housing density does not have a significant effect on summer temperature profiles for the system provided ventilation rates are based on occupancy. Placing the artificial day period in the system out of phase with the natural day can be used to modify temperature extremes and place the period of maximum metabolic activity in phase with minimum system temperatures. Some phase relationships will significantly reduce daily temperature range which previous research has indicated will reduce the bird's ability to cope with thermal stress. The logic based ventilation control system proposed in Section 4.5 reduces thermal stress through increasing diurnal temperature range and reduces operating cost for the ventilation system by using maximum ventilation rates only when they are effective in temperature control. 6. RECOMMENDATIONS FOR FUTURE WORK The results of this research suggest the need for additional work in the following areas: 1. Investigation of bird heat production under conditions of diurnally varying temperature. A primary goal of this work would be the development of a single function which can make a smoother transition between day and night rates than the two separate linear interpolations used in this study. Development of a ventilation rate control system which employs differential sensing to effect the type of ventilation control discussed in Section 4.5. Determination of the actual mass transfer coefficients for evaporation of moisture from the surface of wet manure. A detailed investigation of the influence of the concrete floor slab on environment within the structure. This should include both the the direct exchange of thermal energy with 73 74 the environment and the effect which the slab temperature has on manure surface temperature and subsequent mass transfer rates. Of particular interest would be the effect of either artificially heating the floor slab or reducing its thermal capacitance through the use of insulating materials. Determination of the economic benefits, if any, to be obtained by reducing thermal stress on the bird. Reorganization of the simulation model so that it could be used to study the struc- tural and management factors which influence winter environment in the poultry house.
