| Abstract | Geothermal Heat pump is a new technology in A/C Systems in the world. The aim of this paper is to describe the procedure of design and installation of a geothermal heat pump in Iran. A 18000 BTU/hr air-to-air heat pump has been changed and designed to a geothermal heat pump system for the first time in Iran. Air-to-air condenser has been replaced by a Tube-in-Tube heat exchanger, the assembled system under the ARI-325 standard of the national energy lab of Iran has been tested and the results compared with the original system. The results show notable savings in energy consumption. Local climate conditions and soil properties of Tabriz, located at the north-west of Iran, were used to design the geothermal coil. The coil was connected to the heat pump and average coefficient of performance (COP) of 2.57 has been recorded. |
