REFRIGERATOR WITH LOW-TEMPERATURE SEPARATION, AND REFRIGERATING STORAGE DEVICE Russian patent published in 2013 - IPC F25B7/00 F25D11/02 

FIELD: heating.

SUBSTANCE: refrigerator with low-temperature separation, which contains the following: refrigerating compartment (2) for cooling and storage of product to be stored; freezing compartment (4) for freezing and storage of product to be stored; the first compressor (11) for performing the first cooling cycle (10), in which the first cooling agent flows; the first heat removal device (12) provided in high-temperature section of the first cooling cycle (10); the first evaporator (14) provided in low-temperature section of the first cooling cycle (10); the second compressor (21) for performing the second cooling cycle (20), in which the second cooling agent flows; the second evaporator (24) providing low-temperature section of the second cooling cycle (20); and intermediate heat exchanger (31) for heat exchange between low-temperature section of the first cooling cycle (10) and high-temperature section of the second cooling cycle (20). The first evaporator (14) cools down refrigerating compartment (2), and the second evaporator (24) cools down freezing compartment (4).

EFFECT: reduction of electric energy consumption.
