METHOD OF REFRIGERATOR TEMPERATURE MODES MAINTENANCE WITH APPLICATION OF LOW CLIMATIC TEMPERATURES Russian patent published in 2008 - IPC F25D11/00 F25D3/04 

FIELD: heating.

SUBSTANCE: method of temperature modes maintenance in refrigerating and freezing compartment of refrigerator with application of low climatic temperatures consists in cooling of freezing compartment with evaporator of refrigerating unit, and maintenance of refrigerating compartment temperature by provision of cooling agent circulation in the circuit of thermal tube that removes heat from refrigerating compartment into freezing compartment, at ambient temperature lower than preset top limit of freezing compartment temperature refrigerating unit is disconnected, thus providing circulation of cooling agent in the circuit of freezing compartment evaporator and condenser, which is installed with provision of thermal contact with environment; if ambient temperature is higher than preset top limit of freezing compartment temperature, cooling of freezing compartment is carried out with refrigerating unit, at that control of refrigerating unit operation is performed by readings of temperature detector of freezing compartment, interrupting circulation of cooling agent in circuit of freezing compartment evaporator and condenser; and maintenance of refrigerating compartment temperature within preset interval is performed by readings of temperature detector in refrigerating department by regulation of cooling agent circulation intensity in the circuit of thermal tube and control of refrigerating compartment heater. Application of this invention provides possibility of cooling and maintenance of refrigerator temperature modes with application of low climatic temperatures and independent control of temperature in refrigerating and freezing compartments of refrigerator.

EFFECT: provides possibility of maintenance of refrigerator temperature modes with application of low climatic temperatures and independent control of temperature in refrigerating and freezing compartments of refrigerator.
