At present, the most commonly used vapor compression heat pumps, compressors, evaporators, condensers, and throttle valves are the four main components. Other auxiliary components include fans, four-way valves, liquid storage tanks, gas-liquid separators, copper pipes, and Protectors and electronic control parts used to ensure the normal operation of the machine, etc. Direct-heating models also include a water flow regulating valve.
