COLD ACCUMULATOR Russian patent published in 2002 - IPC

FIELD: refrigerating engineering; industrial heat-power engineering; industries using accumulated cold. SUBSTANCE: cold accumulator includes ice storage located in soil and filled with water. Closed cycle of low-boiling medium includes evaporator unit located above bottom line and condenser unit located above surface of ice storage. Located between evaporator and condenser units on one shaft with pump is turbine; said pump is used for transfer of water cooled by evaporator unit from bottom of ice storage to surface, thus ensuring freezing of ice over entire depth of basin. Intensity of process depends on ambient air and ice storage water temperature gradient. EFFECT: reduced power requirements due to use of natural cold. 1 dwg
