Theoretical analysis of a solar assisted water source heat pump space heating system

Due to the 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. It is possible to estimate the solar radiation values in the selected region with the simulation. The case study is applied and simulation results are given for Antalya, Turkey. The effect of change in the storage tank capacity, collector type and condanser power over the consumed power of the compressor, COP of the heat pump and the overall system are investigated and optimal sizing for the system components are determined. For this system, exergy analysis is also performed with the simulation and irreversibility, improvement potentials and exergy efficiencies of the heat pump and system components are estimated.
