Energy Performance and Environmental Impact of an Earth-Air Heat Exchanger for Heating and Cooling a Poultry House
The poultry industry in Morocco is an important sector that contributes to the growth of national economy and food security, but this sector faces many problems, one of those problems is the climatic conditions, heat stress wave in summer and cold wave in winter that causes mortality and drops in performance (weight drop). Another problem is the relatively high consumption of conventional energy and corresponding environmental impact of the released greenhouse gas emissions.
In this paper, a proposed system for heating and cooling a poultry house is modeled and simulated for the weather conditions of Tangier city-Morocco. The system consists of an earth-air heat exchanger, a mixing box, and an air-air heat recovery, which are combined to control the temperature inside the poultry house efficiently. The results showed that the proposed system has the potential to save between 34.7% and 96% of the energy demand in the heating mode and in the cooling mode respectively. The required number of tubes was found to be around 80 parallel tubes of 0.2 m in diameter and 30 m in length.
