The heart of the compressor's refrigeration system

The heart of the compressor's refrigeration system If a person does not have a heart, it is equivalent to a dead person! The "heart" of a car is the engine. If there is no engine, the car is equivalent to scrap iron. The "heart" of the refrigeration system is the compressor. Now that summer is here, all kinds of air-conditioning, cold storage, chemical refrigeration processes, etc.
