What are the advantages of running dual-source heat pumps that are compatible with both water and air sources?

The company develops a dual-source heat pump compatible with water and air sources, which belongs to the field of heat pump technology. The dual-source heat pump provided in this patent includes compressor, four-way valve, condenser, expansion valve, finned-tube evaporator and water-side evaporator, in which the refrigerant line coming from the condenser is divided into two lines, one is connected to the low-pressure inlet end of the four-way valve through expansion valve and finned-tube evaporator, the other is connected to the suction end line of the compressor through another expansion valve and 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 required. The process of heating with water and air source is realized by a set of equipment, which saves the initial investment cost, floor area and installation cost of the equipment and facilitates the automatic operation of the system.
