REFRIGERATION CYCLE

The refrigeration cycle is a continuous closed-loop system. The refrigerant is pumped constantly through the components in the system. By changing the refrigerant pressure and by removing and adding heat, the refrigeration cycle is completed. The refrigeration cycle operates as follows:

1. The receiver/drier collects high-pressure refrigerant in a liquid form. Also, moisture and impurities are removed at this point.
