Abstract

This thesis presents a comprehensive study of the energy performance of industrial poultry houses, which are among the highest energy consumers due to the high bird density and the constant need to maintain optimal indoor climate conditions. The aim of this study is to assess the potential of an earth-air heat exchanger (EAHE) system as a renewable energy technology to reduce energy consumption and its environmental impact. The study begins with a detailed analysis of the thermal requirements of an industrial poultry house in Biskra, a region with a hot desert climate. A comprehensive thermal model was developed, accounting for heat gains and losses through the building envelope, solar radiation, and internal heat from birds, workers, and equipment. Results showed that the cooling load reached 448.96 kW, which is 4.5 times higher than the heating load of 99.66 kW, highlighting the significant cooling demand in such a climate. The EAHE system was independently designed and studied to evaluate its heating and cooling potential before being integrated into the building. Results demonstrated that the system could meet 45% of the heating needs and 35% of the cooling needs, significantly reducing CO₂ emissions. Numerical simulations were also conducted to analyze system performance post-installation and identify the optimal scenario for air inlet positioning and configuration. The optimal scenario improved internal air distribution. The study concludes that the EAHE system is an environmentally friendly, energy-efficient, and economically viable solution, especially as a supplementary system in large industrial buildings or as a primary system in smaller facilities
