ENERGY REFRIGERATION SYSTEM FOR OPERATION OF AN UNDERGROUND FACILITY Russian patent published in 2023 - IPC G21D5/12 F02G1/04 

FIELD: energy industry.

SUBSTANCE: invention can be used to create energy refrigeration systems for autonomous energy supply and temperature control (cooling) of equipment for underground structures of various functional purposes. The power supply of the underground structure is provided by the operation of a double-circuit nuclear installation, consisting of a nuclear reactor, a liquid circuit and a steam circuit. For the operation of a nuclear plant, process water is supplied through the supply line from the storage of stored process water initially to cool the refrigeration machine, and then to cool the nuclear plant due to heat exchange in the condenser of the steam circuit of the double-circuit nuclear plant. Cooling of cold consumers is carried out according to the scheme of the circulating cooling system. Cold consumers are cooled by supplying cold water at a temperature of 4 to 8°C from a cold water tank through the cold water supply line, cold water passes through cold consumers, and is heated to a temperature of 16 to 19°C and enters the container of the cold supply system for warm water. From the container with warm water, water is fed through the warm water supply line to the evaporator of the refrigeration machine, where it is cooled to a temperature of 4 to 8°C and then enters the container with cold water.

EFFECT: possibility of operation of the energy refrigeration system of an underground structure in two modes with and without communication with the surrounding ground environment, an increase in the life of the energy-refrigeration system without replenishing the source of thermal energy (fuel), as well as an increase in the explosion and fire safety of the energy equipment of the underground structure, reducing the weight and size characteristics of the steam turbines and reduce corrosion of steam turbine blades.
