PROBLEM TO BE SOLVED: To provide an absorption refrigerating machine in which fuel consumption per cooling output is reduced while saving energy by utilizing the function of a boiler sufficiently and which can be handled easily by making compact the entirety of the absorption refrigerating machine. SOLUTION: An evaporative absorption refrigerating machine circulating absorption liquid from an absorber 1 through a low temperature heat exchanger 3, a low temperature regenerator 4, a high temperature heat exchanger 6, a vapor heating high temperature regenerator 7, the high temperature heat exchanger 6 and the low temperature heat exchanger 3 to the absorber 1 comprises a boiler 10 for thermally condensing the absorption liquid interposed between the high temperature regenerator 7 and the high temperature heat exchanger 6, and a pump 13 for extracting concentrated absorption liquid from the high temperature regenerator 7 partially or entirely and supplying it to the solution condensing boiler. The solution condensing boiler 10 is coupled with the high temperature heat exchanger 6 to return the thermally condensed absorption liquid to the heating side thereof and coupled with the high temperature regenerator 7 to supply refrigerant vapor evaporated from the absorption liquid in the solution condensing boiler 10, as a heat source, to the high temperature regenerator 7.
