Abstract
Disclosed is a cold energy recovery-type variable-capacity air-source heat pump system, relating to combined heating and refrigerating systems running in an alternating or synchronous manner, wherein a first subsystem and a second subsystem share a double-channel variable-capacity heat exchanger; a heat exchanger main body includes two manually independent refrigerant pipe pass channels, and a refrigerant in the two channels synchronously carries out heat exchange with hot medium water in a shell pass channel; the shell pass channel establishes a water-medium heat-supplying circulation via a hot water circulation pipeline and a hot water circulation pump; the first subsystem and the second subsystem are connected to the two refrigerant pipe pass channels via a control valve group.
