Abstract

The Korean laying hen industry has become increasingly large-scale and intensive, increasing the need for stable management of indoor thermal conditions, ventilation, and air quality. Ventilation is essential for removing heat, moisture, and harmful gases; however, during seasonal transition periods, outside air can increase heat loss and heating demand. Heat Recovery Ventilation (HRV) can mitigate this limitation by recovering heat from exhaust air to preheat incoming air while maintaining ventilation. This study evaluated the effects of HRV on the indoor environment and heating load of a mechanically ventilated laying hen house using Building Energy Simulation (BES). Field measurements of indoor air temperature, relative humidity, ventilation rate, from a commercial laying hen house in Cheonan, Korea, were used to develop and validate the BES model. Validation results of the BES model showed good agreement between measured and simulated indoor air temperatures, with R2, NMBE, and Cv(RMSE) of 0.91, 1.94%, and 2.66%, respectively, satisfying ASHRAE 2014 criteria. HRV contribution to total ventilation was varied from 10% to 100%, with conventional ventilation as the control. Compared with conventional ventilation, 100% HRV increased average indoor temperature from 18.21°C to 18.65°C and time above 18°C from 45.14% to 75.93%. Average ventilation increased by 52.8%, while non-ventilation time decreased from 46% to 22%. Total heating demand decreased by 75.6%, with maximum and average hourly heating loads declining from 0.28 and 0.09 GJ·h-1 to 0.11 and 0.02 GJ·h-1, respectively. HRV improved thermal stability and reduced heating demand during seasonal transition periods.
