Abstract
The utility model relates to an air source heat pump system comprising a solar collector, an evaporator, a heat-storage water tank, a communicated pipeline, an electromagnetic valve unit and an intelligent control module. The evaporator is a double-path evaporator and is provided with a first flow path in which coolant flows, and a second flow pass is added on the basis of the original first flow pass. When the temperature of heat medium in the solar collector reaches 27-35 DEG C and meets operating conditions of an air source heat pump, the intelligent control module controls a first control valve and a second control valve to open, and meanwhile, a third control valve and a fourth control valve close; when the temperature of the heat medium in the solar collector is higher than 35 DEG C and exceeds the operating conditions of the air source heat pump, the intelligent control module controls the first control valve and the second control valve to close, and meanwhile, the third control valve and the fourth control valve open. The second solar-assisted flow path is added to the original evaporator, the temperature of the evaporator is increased, and the common problem of frosting is avoided.
