SUBSTANCE: refrigerator consists of a switchable temperature compartment, a cooler unit generating chilled air, a blower fan, an inlet valve for opening/closing the air supply duct connecting the cooler unit to the blower fan, a check valve for opening/closing the air recovery duct connecting the cooler unit to the outlet port therethrough air is discharged from the switchable temperature compartment and a regulator valve for opening/closing the air connective duct connecting the circulation port arranged in the switchable temperature compartment to the blower fan inlet side. When the inlet valve and the check valve are open the regulator valve is shut off; when the regulator valve is open the inlet valve and the check valve are shut off. A single damper on recovery of air from the switchable temperature compartment is used both as the check valve and the regulator valve. There is a single port arranged to be used both for outlet and circulation with the air recovery duct and the connective duct branching from the port separated by the damper on recovery of air from the switchable temperature compartment. The above damper has a two-way diaphragm switching between its two positions thus alternately shutting off the connective duct and the air recovery duct.

EFFECT: uniform distribution of temperature.

SUBSTANCE: method of thermostatting low-temperature food product freezer rooms with closed refrigeration cycle. A coolant chilled from outside by heat exchange with a flow of cool low-pressure natural gas is used as an intermediate heat transfer medium. The above gas flow is produced in a vortex energy dividing device by reducing the pressure of the part of high-pressure natural gas flow which is supplied to the gas-reducing station of the gas main. The hot gas flow and the cool flow being heated and produced in the energy dividing device are combined and withdrawn into the low-pressure consumer gas network.

EFFECT: reducing energy demand for the system operation.
