This book aims to evaluate the thermal performance and feasibility of integrating Earth-Air Heat Exchanger (EAHE) with the building's vapor compression air cooling system in the hot climate of Arab gulf region or any similar climates. In the proposed system, the ambient air is forced by an axial fan through an EAHE buried at a certain depth below the ground surface. EAHE uses the subsoil low temperature and soil thermal properties to reduce the cooling air temperature. The outlet air from the EAHE is used for the purpose of cooling the condenser coil of a vapor compression cycle (VCC) based air conditioning system to enhance its coefficient of performance (COP). The potential enhancement on the COP was investigated for two different refrigerants (i.e. R-22 and R410a) cooling systems. A mathematical model was developed to estimate the underground soil temperature at different depths and the corresponding outlet air temperature of EAHE was calculated.
