Simulation study on performance of a dual-source hybrid heat pump unit with alternative refrigerants
Energy and Built Environment, 2020 To solve the problems of single heat source heat pump systems in severe cold regions, a dual-source hybrid heat pump unit (DSHHPU) is proposed. The mathematical models of the DSHHPU when charging R134a or its alternative refrigerants R32, R290 and R600a ...
