The company develops a dual source heat pump with residual heat recovery unit, including a compressor, a first heat source system in parallel with a second heat source system. The first heat source system includes a gas-liquid separator connected to a compressor, a first condenser connected to a gas-liquid separator, a first expansion valve connected to a condenser, and an evaporator connected to a compressor and a first expansion valve, respectively. The second heat source system includes a heat exchanger connected to the compressor, a second expansion valve connected to the heat exchanger, a reservoir connected to the second expansion valve, and a second condenser connected to the reservoir and the compressor respectively. The first condenser and the second condenser are connected with a residual heat recovery device, which is a dual-source heat pump with residual heat recovery device. Through the effective structure of the boiler heat exchanger, it can easily provide more heat to meet higher needs. The residual heat recovery unit can effectively recover excess energy, thus saving energy.
