개요
This study aimed to determine the optimal ventilation rate for mechanically ventilated pig houses in summer to enhance heat exchanger efficiency and improve the livestock environment. Using Computational Fluid Dynamics (CFD) simulations, the study analyzed airflow patterns and calculated the effective temperature (ET) under various ventilation conditions. The results revealed that a 60% ventilation rate provided the optimal balance between reducing ambient temperatures and maintaining ammonia levels within acceptable limits. Furthermore, temperature uniformity and ammonia
distribution indicated areas requiring improved airflow management. This research underscores the necessity of integrated cooling and ventilation systems in pig houses during summer, offering insights to enhance productivity and animal welfare in livestock operations.
