AB - Due to use of alternative energy sources and energy efficient operation, heat  pumps come into prominence in recent years. Especially in solar-assisted heat  pumps, sizing the required system is difficult and arduous task in order to  provide optimum working conditions. Therefore, in this study solar assisted  indirect expanded heat pump space heating system is simulated and the results  of the simulation are compared with available experimental data in the  literature in order to present reliability of the model. Solar radiation  values in the selected region are estimated with the simulation. The case  study is applied and simulation results are given for Antalya, Turkey.  Collector type and storage tank capacity effects on the consumed power of the  compressor, COP of the heat pump and the overall system are estimated with  the simulation, depending on the radiation data, collector surface area and  the heating capacity of the space. Exergy analysis is also performed with the  simulation and irreversibility, improvement potentials and exergy  efficiencies of the heat pump and system components are estimated.
