Summer brooding often requires some form of air modification in
addition to maximizing ventilation rate to prevent animal heat stress
and possible death due to hyperthermia. A rockbed thermal storage
module was designed and constructed to provide sensibly cooled air
for a broiler space under summer brooding conditions. A mathematical
model of rockbed thermal storage module was developed to predict
performance of the prototype module. Experiments to evaluate the
rockbed module under different weather conditions and operating
schedules were conducted. The results were presented and compared
with the mathematical simulation.
A microprocessor control system was designed and assembled to
control the ventilation air that would enter a broiler house during
warm weather periods. The system was capable of taking temperature
samples from thermocouples and then operate a damper arrangement
which determined the mixture of outdoor and sensibly cooled air from
rockbed thermal storage module. The cost and feasibility of
utilizing a rockbed thermal storage module and a microprocessor
control ventilation system were discussed. / Graduation date: 1989
