Abstract or Summary
  • 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.
