Zusammenfassung: | PURPOSE: To perform cooking without stopping the operation of a compressor by controlling ON, OFF a circulation pump when a cooling load becomes overload. CONSTITUTION: A refrigerant circulating circuit has a compressor 1, an evaporation type condenser 2, an expansion unit 3, an evaporator 4 and an accumulator 5. A chilled water circulating circuit circulates chilled water cooled by the evaporator 4 of the refrigerant circuit by a circulation pump 10 to an indoor heat exchanger. When the overload state of the refrigerant circuit is detected, the operation of the pump 10 of the water circuit is stopped in the state that the operation of the compressor 1 is continued, and the overload control is started. When the refrigerant circuit is reset from the overload state to a normal load state without a preset standby time, the operation of the pump 10 of the water circuit is restarted, and the overload control is stopped. When the refrigerant circuit is not reset from the overload state to the normal load state within the stand-by time, the pump is controlled to be ON, OFF before the compressor 1 is stopped. |
