METHOD OF FOOD PRODUCT FREEZER ROOMS THERMOSTATTING Russian patent published in 2009 - IPC F25D3/00 F25D17/08 F25B25/00 

FIELD: technological processes.

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 The hot gas flow and the cool flow being heated and produced in the energy dividing device are combined and withdrawn into the low-pressure consumer gas network.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.
