Basic knowledge of air energy

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.
