ABSTRACT:
A refrigerating fluid which has passed through the cooler of a refrigerating apparatus during the defrosting cycle and is thus partially liquid and partially gaseous, is fed under pressure into a heat exchanger containing a radiator and a plurality of expansion tanks. The refrigerating fluid in the combined gaseous and liquid state is fed into the evaporating tank about which hotter air is circulated by means of an air circulating fan which causes warm air coming from the radiator to be circulated about the tanks, thus causing an increase in temperature of the fluid causing it to evaporate and leaving no remaining liquid as the fluid leaves the evaporating tanks. The gaseous fluid is then directed to the compressor by which it is fed into a radiator where it tends to heat the radiator, thus providing the warm air for circulation over the evaporator tank. The refrigerant fluid is then passed in the gaseous state from the radiator to the cooler wherein it defrosts the evaporating coils in the cooler and is thus returned to a partially liquid and partially gaseous fluid which is then recirculated to the evaporating tanks of the heat exchanger, completing the cycle.
