PROBLEM TO BE SOLVED: To prevent adverse influences of noncondensing gas in an absorption refrigerating machine. SOLUTION: An absorption refrigerating machine includes a condenser C, an absorber A and an evaporator E and a plurality of regenerators Gn to G1 and solution heat exchangers Hn to H1 corresponding to each of the regenerators Gn to G1 . The absorption refrigerating machine introduces refrigerant vapor that is generated in the regenerators Gn to Gn2 on the higher temperature side to the regenerators Gn-1 to G1 on the lower temperature side sequentially and uses the refrigerant vapor as a heat source for the regenerators Gn-1 to G1 . In the absorption refrigerating machine, noncondensing gas pipes 51, 52 and 53 through which noncondensing gas flows are communicated with each other between the higher-pressure side devices Gn to G1 that are located between the regenerator Gn to the highest temperature side and the absorber A, and the lower-pressure side devices Gn-1 to G1 , C, E and A. By using the difference in pressure between the devices on the higher pressure side and the devices on the lower pressure side, it becomes possible to flow the noncondensing gas from the higher pressure side to the lower pressure side.
