Özet
The Solar Energy Assisted Heat Pump (SAHP) system is modeled by creating different processes with the help of various models created in the JAVA program. The SAHP model was created in order to obtain hot water by utilizing solar energy. The inlet water temperature in the system was taken as 10 °C in December and 20.5 °C in June and the SAHP model was analyzed by numerical method. In the evaporator model, considering the coordinates of the city of Izmir, various graphs were created by calculating the different spectral solar energy values falling on 1 m2 evaporator plate on certain days of 2019. In the graphics, the highest energy density on 1 m2 evaporator plate for İzmir province was 852.095 W/m2 on 21 June at 12:00, and the lowest energy density was 455.143 W/m2 on 21 December at 12:00. In the SAHP system, the evaporator plate area was determined as 2.40 m2 and the compressor power was 0.56kW, and a condenser model was created. The required condenser surface areas were found by calculating the thermal energies given by the condenser for different dates in the system. In the modeling of the heat pump, the Coefficient of Performance (COP) of the SAHP system for R134a and R404A was obtained by taking the date of June 21, 12:00, when the spectral energy is most intense, as a reference.
