Özet
In this study, the performance of a geothermal heat pump used in heating mode for a house whose heating energy need is determined according to the Turkish thermal insulation standard TS 825, with different refrigerants has been theoretically analyzed. Accordingly, the annual heating energy need was calculated by taking the building components of the house into consideration, and it was determined that the heat pump condenser to meet this need should have a capacity of 15 kW. In addition, 7 different refrigerants with zero ozone depletion potential (ODP) in the heat pump system were annalized at variable evaporator temperatures and the performance of the geothermal heat pump was investigated. In the study, thermodynamic analysis was applied to the system by using Hydrochlorofluorocarbons (HFC) refrigerant types R 134a, R 143a, R 404A, R 407A, R 407C, R 410A and R 507A refrigerants for the determined operating conditions of the geothermal heat pump. Solway Solkane 8.0 calculation program was used for analysis. As a result of the analysis, it has been determined that the lowest operating loads and the highest heating effect coefficient values for the same operating conditions will be obtained from the system using R 134a, R407A, R 407C refrigerants, respectively. Moreover it was determined that the refrigerant with the highest pressure ratio value was R 134a.
