In this research, a 47m long horizontal, 56cm nominal diameter U-bend buried galvanized was studied experimental EAHE used for the determination and evaluation of thermal properties of heat exchanger. This system was designed and installed in the Solar Energy Institute, Ege University, Izmir, Turkey. Based on the experimental results, generalized relationships were developed for predicting of thermal resistance of the heat exchanger. Average total heat exchanger thermal resistance was estimated to be 0.021K-m/W as a constant value under steady state condition. © 2011 Elsevier Ltd.EnglishGeothermal energyHeat exchangersSolar energyThermodynamic propertiesClosed loopsCooling applicationsEAHEEarth-to-air heat exchangerEnergy InstituteGreenhouse coolingRenewablesSteady-state conditionThermal propertiesThermal resistanceTotal heat exchangerHeat resistanceArticle10.1016/j.icheatmasstransfer.2011.03.009
