摘要

In this study, the usage of geothermal sourced heat pumps in district heating system was investigated By this way, Kutahya-Simav geothermal resources, amongst the 15 largest area of Turkey, were taken into account. The proposed system for geothermal sourced heat pump district heating cycle consists of four sub-circuits. The Circuit I is geothermal flow cycle which transfers the heat from the geothermal fluid to evaporator, Circuit II is heat pump cycle, Circuit III is district heating cycle and Circuit IV is residential heating cycle. Different refrigerant fluids such as R-134a, R-22 and R-600a were evaluated in system using energy and exergy analysis. As conclusion, the maximum COP_(sys) and overall efficiency of system were obtained for R-22 where maximum number of heated residence was obtained for R-134a.
