Wet-Bulb and Dew-Point Evaporative Cooling Options for Poultry Sheds

Abstract

The present study addressed the applicability of evaporative cooling (EC) systems for poultry birds. In summer, climatic conditions are not favorable for the thermal comfort of poultry birds. Cooling systems available in the market are not energy efficient and cause global warming. Evaporative cooling systems are energy-efficient, low-cost, and environment-friendly options for the thermal comfort of poultry birds. Three kinds of EC systems: direct, indirect, and Maisotsenko cycle-based evaporative cooling (DEC, IEC, and MEC) systems are studied for poultry houses. The performance of the systems is investigated in terms of wet-bulb effectiveness. Temperature-humidity index (THI) is also calculated based on output results to check the thermal comfort of the poultry birds. According to the results, the MEC system performs better as compared to the old DEC and IEC systems. However, the performance of the systems is limited in humid areas.
