Problems solved by technology

The series non-direct expansion solar heat pump hot water system has only one working mode. The solar device is used to increase the evaporation temperature of the heat pump, thereby increasing the exhaust temperature of the compressor. Obviously, this design is suitable for low ambient temperature. The problem of low COP of heat pumps in low temperature environment, this kind of device is rarely used in practice, because only the solar collector in the whole system becomes the heat source for heating, and the efficiency of a single source is low
