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.

Refrigeration system failure symptoms

Symptoms of refrigeration system failure 　 　 　 　 1. Detection of pressure and temperature of refrigeration system　　 (1) The pressure concept of the refrigeration system The refrigeration system can be divided into high and low pressure during operation. The high pressure section is from the discharge port of the compressor to before the throttle valve. This section is called the evaporation pressure.
