The company develops a dual source heat pump compatible with water source and air source, which belongs to the technical field of heat pump; The dual source heat pump provided by the patent includes a compressor, a four-way valve, a condenser, an expansion valve, a finned tube evaporator and a water side evaporator. The refrigerant pipeline from the condenser is divided into two ways. One way is connected with the low-pressure inlet end of the four-way valve through the expansion valve and the finned tube evaporator, and the other way is connected with the suction end pipeline of the compressor through another expansion valve and the water side evaporator; The dual source heat pump provided by the utility model is mainly used in places where both water source heat pump and air source heat pump are needed. The heating process of water source and air source is realized through a set of equipment, which not only saves the initial investment cost, floor area and installation cost of the equipment, but also facilitates the automatic operation of the system.
