DEVICE FOR COLD ACCUMULATION Russian patent published in 2012 - IPC F25D1/00 F25D3/00 

FIELD: personal use articles.

SUBSTANCE: device for cold accumulation includes an ice storage, a heat exchanging circuit, which is filled with a liquid cold-transferring agent with freezing temperature of - 60° C, a heat exchanging unit arranged in the ice storage and a heat exchanging unit arranged in a refrigerating chamber, supply and drain channels and a pump. The heat exchanging unit, which is arranged in the ice storage, comprises the first and second vertical headers with at least two horizontal headers and arranged in the ice thickness in parallel to each other at different levels at height. Cavities of horizontal headers are communicated with a horizontal register, having ribbing and comprising at least two pipes. The cross section of the vertical header is less than the sum of cross sections of horizontal headers, which in its turn is less than the sum of cross sections of horizontal registers. The heat exchanging unit, which is installed in the refrigerating chamber, is arranged as capable of operation in one of two modes, or with cold extraction from the ice storage, or with cold extraction from outer air at its temperature below - (40-60°C) and its supply into the ice storage.

EFFECT: possibility to establish a device for cold accumulation, with simplification of its design and reduction of power consumption, increased duration of accumulated cold usage.
