Abstract:
1. An absorption refrigerating machine comprising: a high temperature regenerator, a low temperature regenerator, a condenser, an evaporator, an absorber, a low temperature heat exchanger for performing heat exchange between absorbent solutions entering and leaving the absorber, a high temperature heat exchanger for performing heat exchange between absorbent solutions entering and leaving the high temperature regenerator, a first heat recovery device for collecting heat remaining in a heat exhaust fluid discharged from the high temperature regenerator after heating an absorbent solution in the high temperature regenerator through heat exchange between the heat exhaust fluid and the absorbent solution leaving the absorber and flowing into the low temperature heat exchanger, and a second heat recovery device upstream, with respect to the heat exhaust fluid, of the first heat recovery device for collecting heat remaining in the heat exhaust fluid through heat exchange between the beat exhaust fluid and absorbent solution discharged from the low temperature heat exchanger, and flowing into the high temperature heat exchanger.
