AIR COOLING METHOD IN CLOSED CAVITY OF DOMESTIC REFRIGERATOR AND DEVICE FOR IMPLEMENTATION OF ABOVE METHOD Russian patent published in 2011 - IPC F25B1/00 

FIELD: heating.

SUBSTANCE: air cooling method consists in the fact that cooling agent vapours circulating via closed circuit are concentrated, cooled, condensed and throttled. Then, heat is supplied to cooling agent and it is converted to gaseous state so that cooling agent vapours are formed with the specified minimum temperature. Air is cooled by means of accumulator which is pre-cooled during the cooling agent circulation by means of heat exchange with circulating cooling agent to the temperature which is lower than the specified minimum temperature of air cooling. Then, cooling agent circulation is stopped and air is cooled by heat removal from cooled air to the accumulator. Air cooling device includes closed circuit having the device for increasing the cooling agent concentration, condenser, throttling device and device for heat supply to cooling agent. Device for heat supply to cooling agent is located in upper part of closed cavity with cooled air and represents heat accumulator and is made from metal with high heat conductivity. Finning is made on outer surface of accumulator.

EFFECT: reducing electric energy consumption.
