ABSTRACT One of the most consumed energy sources today is fossil-based fuels. While the reserve of these fuels is declining, it continues to be the main cause of environmental pollution. Due to the influence of environmental factors and increases in fuel costs has accelerated the search for new sources of energy, the importance of alternative energy sources as a result of increased even more. A the same time the increasingly severe global warming and energy crisis have made it urgent to explore appropriate renewable energy for building use, particularly for the HVAC systems. At 2030, heat pumps; 50% of new buildings and 30% of the reinforcing building when used, is expected to reduce CO2 emissions by 40%. In this study, ground source heat pump was operated in the heating mode having diverse concentration ratios with several volumetric flow rates the ground source heat pump(GSHP) heating performance was investigated experimentally. The experiments were carried out in room conditions of dimensions 3 x 3 x 3 m. The experimental device consists of two cycles: The test setup consists of two cycles: under-ground and over-ground. Equipment’s such as rotary compressor, condenser, evaporator (plate-brazed exchanger), expansion valve and four-way valve have been used in the over-ground circulation of the heat pump. The under-ground cycle consists of the pump and the 1 inch diameter nickel-chromium 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. In experimental studies, the GHSP system was operated on water-ethylene glycol with diverse concentration ratios ranging from 0 to 30% and volumetric flow rates ranging from 10 to 27 L / min. The system, condenser and evaporator capacities, COP and heating capacity and changes in the temperature of the heated room (Toda) were investigated. According to the experimental results obtained, the best results were obtained with a mixing ratio of 5% and a volumetric flow rate of 21 L / min. Under these conditions, the evaporator capacity=4.2 kW, condenser capacity= 5 kW COP = 3.4, Toda = 27.2 ° C.
