REFRIGERATOR FOR OPERATION WITH USE OF LOW CLIMATIC TEMPERATURES Russian patent published in 2009 - IPC F25D11/02 F25D3/02 

FIELD: heating.

SUBSTANCE: refrigerator for operation with use of low climatic temperatures contains a heat-insulated case with freezing and refrigerating sections, refrigerator set which evaporator is installed in the freezing section, heat rejection device for abstracting heat from the refrigerating section, the said heat rejection device being made in the form of a thermal pipe which condenser site is installed so as to maintain thermal contact with the refrigerator set evaporator. The thermal pipe evaporation site is located in the refrigerating section. To highways of the refrigerator set detachably jointed is a condenser with separate channels for gas and liquid, arranged outside the heated premises, on which gas supply highway a NO return valve is arranged. The thermal pipe rejecting heat from the refrigerating section to the freezing one is equipped with separate channels for gas and liquid, with a NO valve installed on the gas channel. The refrigerator shell also incorporates an in-built heater and remotely programmed processor connected, by means of control circuits, to the refrigerator set compressor, thermal pipe valve and the heater and, by means of metering circuits, to environment temperature gauge and temperature gauges in freezing and refrigerating sections of the refrigerator.

EFFECT: invention enables independent temperature adjustment in refrigerating and freezing sections of refrigerator.
