Analysis of the effects of heat recovery ventilation in a laying hen house during the winter using computational fluid dynamics
Year: 2025
Type: article
Abstract: This study investigated the impact of a heat recovery ventilation (HRV) system on the winter indoor thermal environment of a laying hen house using CFD simulations, based on Ministry of Agriculture design standards.HRV operation rates were varied from 100% to 10% to assess their effects on indoor temperature distribution and uniformity via a Uniformity Index (UI).An 80% HRV operation achieved the optimal target temperature of 20 °C for maximized laying rate, while rates above 50% maintained the recommended range of 18-24 °C.Temperature distribution exhibited greater vertical imbalance compared to horizontal, and average winter outdoor conditions indicated the target temperature could be reached without HRV.Nonetheless, HRV provided improved indoor air quality through enhanced ventilation, offering valuable insights for designing and optimizing HRV systems in laying hen houses.
