Heating capacity of an earth to air heat exchanger in arid regions - Experimental investigation

Heating capacity of an earth to air heat exchanger EAHE equipped with exterior fan in arid region as the South west of Algeria was investigated experimentally. In-situ measurement of aual undisturbed subsoil vertical temperature profile has showed that it was 28 °C at a depth of 1.5 meter. The EAHE made of 66 meters of PVC tube showed a heating capacity of 13 °C and cooling capacity of 7 °C and a big dependence to local climate conditions. Great potentials and thermal comfort with less energy consumption are represented by earth to air or air ground heat exchanger in arid region like the South of Algeria.
