DEVICE FOR COOLING USER OF REFRIGERATION WITH SUPERCOOLED LIQUEFIED GAS Russian patent published in 2023 - IPC F25B19/00 

FIELD: refrigeration engineering.

SUBSTANCE: device for cooling the user of refrigeration with supercooled liquid in the cooling circuit has a cold cooling circuit (2) and a reservoir (3) for replenishing the cooling circuit, connected through a supply pipeline equipped with a throttle valve (10). The cooling circuit comprises a connected cooling vessel (4), a cryogenic liquid velocity reduction device (15), a circulation pump (7), a user of refrigeration (5), a control valve (18), a cryogenic liquid velocity increase device (11). The cooling vessel (4) comprises an upper part, a lower part and a cylindrical part located between them. The cooling vessel (4) is connected to the atmosphere directly or through a vacuum pump (8). The outlet from the device (11) is connected to the upper part of the cooling vessel and is directed tangentially relative to the axis of the cylindrical part of the cooling vessel. The outlet from the device (15) is connected to the lower part of the cooling vessel and is directed tangentially relative to the axis of the cylindrical part of the cooling vessel.

EFFECT: reduced consumption of energy in the device spent for compressing the pumped-out vapours of the cryogenic liquid, as well as a reduced mass and size of the device for supercooling the cryogenic liquid.
