ABSTRACT:
An absorption type refrigerator capable of returning an abnormally high temperature of heating water or an abnormally low temperature of cooling water to a normal temperature without stopping or switching the operation of the refrigerator is structured such that return heating water 46b is heated with refrigerant vapor 7a in a heater 41 and is provided to a heating load 310. When the temperature of the heating water 46a becomes abnormally high because the heating load 310 is small or zero, the switch valve V1 is opened to cool part of heating water 46a with part of cooling water 32 for heat radiation so as to reduce the temperature of the heating water 46a to a normal temperature. The heat of the heating water 46a may also be radiated by an air-cooled heat exchanger provided along the passages 44 and 45 of the heating water 46a. When the temperature of the cooling water 32 becomes abnormally low at the start of the operation of supplying cooling water 35b because the outside temperature is too low, the switch valve V1 is opened to heat part of the cooling water 32a with part of the heating water 46a in a radiator 51 to increase the temperature of the cooling water 32a to a normal temperature.
