Abstract

This invention relates to refrigeration engineering, in particular to multi-compartment domestic refrigerators. The aim of the invention is to improve the performance by expanding the range of temperatures installed in the refrigerating chambers and eliminating the influence of the thermal regime of any chamber on the operation of the remaining chambers of the refrigerator. When the refrigeration unit is turned on, the cooling element 7 lowers the temperature of the working fluid in the tank 6 to the set temperature of the freezing chamber 3, hermetically mounted into the container 6 with the working fluid below the cooling element 7. If necessary, turn on the temperature-controlled valves 12 and 13, ensuring circulation of the working fluid from the tank 6 through heat exchangers 10 or 11 in these chambers through pipes 14 or 15 and 16 or 17. The increment in the circulation of the working fluid in the shut off heat exchanger of one of the chambers does not affect the circulation of the fluid in t heat exchangers other chambers. 1 hp f-ly, 3 ill.

The sensors 18 and 19 of the thermostatic valves 12 and 13 are located in the respective chambers 4 and 5 and are attached to the discharge pipes 16 and 17.

25, an additional fragmentation occurs with respect to the cold fluid flow and its intensive mixing with the fluid flows heated at the external walls of the heat exchanger.

The temperature of the working fluid in the heat exchanger can take any value in the range from the temperature in the freezing chamber 3 to the ambient temperature, depending on the value of the flow rate determined by the thermostatic valve, circulating through the heat exchanger. The termination of the circulation of the working fluid in the disconnected heat exchanger of one of the chambers does not affect the circulation of the fluid in the heat exchangers of the other chambers. At the same time, neither the number of refrigerating chambers nor the temperature regimes established in them reduce the efficiency of the refrigeration unit, which provides improved consumer properties of a multi-chamber refrigerator.
