Abstract
A hot gas defrost system for a refrigeration cycle, including at least a compressor, reversing valve, condenser and evaporator. During defrost, the reversing valve directs the superheated refrigerant from the compressor to the evaporator. The hot gas traverses the evaporator coil which, in turn, causes the ice or frost to melt. The hot gas defrost refrigeration system may also include a receiver to store the refrigerant during the refrigeration and defrost cycles.
