In the present study, an absorption refrigeration system, which is alternative to the ordinary mechanical refrigeration system, is designed. For this purpose, an experiment using geothermal energy in the Hot Spring in Sivas is set up in the lab conditions, and a thermodynamic analysis of the Absorption Refrigeration System (ARS) operating on water-lithium bromide is performed. The change in the coefficient of performance of the ARS has been graphically investigated with the various parameters and the results are tabulated. These results show that geothermal energy in the Hot Spring in Sivas cannot be used efficiently in electricity generation. However, taking into account the need of storing at 4-10 degrees C, this geothermal resource can be used especially for refrigeration, and it will provide a considerable economical gain.
