ADDITIONAL COLD ACCUMULATOR Russian patent published in 2010 - IPC F25D3/00 

FIELD: heating.

SUBSTANCE: additional cold accumulator includes heat-insulated container, closed cooled liquid circulation circuit. Closed circuit consists of container, pump, device with a jacket, header, liquid flow distributor, temperature sensor, gas tank connected to container, and circuit control units controlled from temperature sensors through receiving-matching device. Circuits consist of open circuit of supply and generation of carbon-dioxide ice, which consists of in-series connected tank with carbon dioxide under pressure, controlled valve, device for supply and expansion of liquid carbon dioxide, open removal circuit of gaseous carbon dioxide, which consists at least of two in-series connected controlled valves, moisture separator, compressor, receiver, pressure sensors, low-temperature condensate turbine, generator; air cooling circuit consisting of temperature sensors and axial fan. In heat-insulated container there installed is upper limit liquid level control and additional permeable container.

EFFECT: saving of electric energy and generated cold.
