A compressor, an inertial fluid machine that elevates low-pressure gases to high-pressure gases, is the heart of the refrigeration system. It sucks in low-temperature and low-pressure refrigerant gases from the suction pipe, compresses them by driving the pistons with the motor, and then discharges the high-temperature and high-pressure refrigerant gases into the discharge pipe, providing power for the refrigeration cycle, thus realizing the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption).
