PROBLEM TO BE SOLVED: To provide an absorption refrigerating machine capable of improving a coefficient of performance, saving energy and miniaturizing the machine as a whole while keeping a function as the parallel flow double effect absorption refrigerating machine. SOLUTION: In this absorption refrigerating machine, dilute solution from an absorber 1 is divided through a low temperature solution heat exchanger 40, one of them is sent to a high-temperature regenerator 6 through a high temperature solution heat exchanger 5, the other is sent to a low-temperature regenerator 7, and the dilute solution is concentrated by the regenerators 6, 7. The low-temperature regenerator 7 uses a refrigerant separated by the high-temperature regenerator 6 as a heating source. The dilute solution from the absorber 1 is divided before the low-temperature solution heat exchanger 40, the divided dilute solution is sent to a refrigerant drain heat recovering unit 10, the dilute solution from the refrigerant drain heat recovering unit 10 is joined before a flow-dividing part 52, and the refrigerant drain from the low-temperature regenerator 7 is supplied to exchange the heat with the dilute solution of the refrigerant drain heat recovering unit 10.
