ABSTRACT:
A compression type refrigeration system including at least one frosting evaporator positioned to refrigerate air. The evaporator has a liquid refrigerant inlet to which is connected an expansion valve. The evaporator also has a hot gas inlet; a liquid line supplies liquid to the expansion valve; a branch in the liquid line controlled by a solenoid valve connects to the hot gas inlet. The condensing unit, which includes compressor, condenser, receiver and re-evaporator, are valve-controlled so that during refrigeration, discharge gas from the compressor flows through the condenser, receiver, liquid line and expansion valve seriatim, but during defrost, gas from the compressor bypasses the condenser and flows instead from the compressor through the receiver, liquid line and hot gas inlet of the evaporator seriatim.
