Summary
An advanced dual-source R744 two-stage parallel compression hot water heat pump system (DEPC) was proposed by combining a dual-source system with a two-stage parallel compression system. Both air and ground heat were taken as the heat sources, which can effectively improve the stability and system performance of heat pump system. The model of the system was analysed and established, and then programs were written in MATLAB to simulate the system. Taking COP as the main criterion, the maximum COP and optimal state point of the system were found out. Furthermore, the system was compared with the conventional dual-evaporator system (DE), and the superiority of the optimized system was presented.
