This Danfoss hot bypass regulator is designed for refrigeration systems using R22 refrigerant. It features inlet and outlet connections with diameters of 3/8 inch and 1/2 inch, respectively. The regulator is utilized to bypass a portion of the hot gas from the discharge side directly to the low-pressure side of the system, which helps in maintaining a minimum compressor load and preventing the evaporator from freezing during low load conditions.
