  • The Different Types of Cooling Compressors

    A compressor acts as the “heart” of a refrigerant-based mechanical cooling system. Its functions include drawing in the cool vaporized refrigerant that carries the heat energy from the evaporator coils, compressing it from a low pressure and tempera-ture to a high pressure and temperature, and pushing it around the refrigeration
