Abstract

PURPOSE: To effectively utilize the energy and to reduce the operation expense by absorbing cold thermal energy in brine in the brine tank, by providing with gas- liquid heat exchanger exchanging heat with a fixed temperature open air.
CONSTITUTION: The pump 10 is provided with the brine tank 5 and when a temperature of open air is lowered at less than a fixed below-zero temperature, said temperature is detected by the temperature switch 12 and operation command is given to said pump 10 at the publicly known above-mentioned apparatus composed of the refrigerator 1, the brine tank 5 and the freezing vessel 7 of the sludge 8. The brine 4 is sent to the gas-liquid heat exchanger 11 by pump 10 and is cooled by exchanging heat with the open air and then, is returned to tank 5. By said construction, the time necessary to cool brine 4 below a fixed temperature, is shortened and the time of stopping the refrigerator is quickened. Accordingly, cold thermal energy is effectively utilized at the place generating it regularly or winter seanon cold district.
