摘要： IN A TWO-TEMPERATURE REFRIGERATOR WHEREIN THE DEFROSTING OF THE COOLER EVAPORATOR IS EFFECTED BY NATURAL THAWING DURING THE PERIODIC INOPERATIVE PERIODS OF THE REFRIGERATING APPARATUS IN ORDER TO EXPEDITE SAID DEFROSTING, THE LIQUID REFRIGERANT PRESENT IN THE COOLER EVAPORATOR UPON STOPPAGE OF THE COMPRESSOR IS FORCED INTO THE FREEZER EVAPORATOR BY PNEUMATIC PRESSURE GENERATED BY THE EVAPORIZATION OF A SMALL QUANTITY OFF LIQUID REFRIGERANT INTRODUCED INTO THE COOLER EVAPORATOR THROUGH A CAPILLARY TUBE AT THE BEGINNING OF THE INOPERATIVE PERIOD.
