Özet: This experiments were carried out in a room with measuring 3x3x3 m. The experimental device consists of two cycles: underground cycle and heat pump cycle. Heat pumps cycle; consists of a rotary compressor, condenser, evaporator, expansion valve and four-way valve. The underground cycle consists of the pump and the 1 inch diameter nickel-chrom pipes laid horizontally at 3 m depth were used as ground heat exchanger. In addition, R22 refrigerant is used as the working fluid in the heat pump cycle. The GSHP system for heating purposes is operated at different water-ethylene-glycol mixture ratios such as 5%, 10%, 15%, 20%, 25%, 30% and 10-27 L/ min .The temperature of the GSHP system operated under these conditions, the temperature of the room to be heated (Toda), the condenser and the evaporator capacity, and the effect of the system on the COP parameter was investigated. According to the results of the tests, the best results in terms of the parameters mentioned were obtained with a mixing ratio of 5% and a volumetric flow rate of 21 L/ min and the highest COP is 3.4 and Toda is 27.2°C.
