PROBLEM TO BE SOLVED: To make it unnecessary to use a heavy-sectioned material or a corrosion-resistant material by further improving thermal efficiency and lowering regeneration pressure and regeneration temperature in a triple effect absorption refrigerating machine. SOLUTION: An absorbing solution which has absorbed a refrigerant in an absorber 6 is heated by an intermediate regenerator 2 before entering a high temperature regenerator 1, and part of the refrigerant absorbed in the absorbing solution is separated by evaporation. The solution is returned to the absorber 6 via a low temperature heat exchanger 7, an intermediate temperature heat exchanger 8, the intermediate temperature regenerator 2, a high temperature heat exchanger 9, the high temperature regenerator 1, the high temperature heat exchanger 9, the intermediate temperature heat exchanger 8, a low temperature regenerator 3A, a second low temperature regenerator 3B, and the low temperature heat exchanger 7 in this sequence so as to enter the high temperature regenerator 1 after its volume has been reduced.
