The steam generated in the regenerator of the side cycle (a) is absorbed by the absorber of the high pressure side cycle (b). That is, as shown in Fig. 1, this two-stage absorption refrigerator consists of an evaporator (11) in which the fluid to be cooled gives heat of evaporation to the refrigerant and becomes cold water, and an evaporator (11 in which the refrigerant is evaporated and vaporized and absorbed into an absorption liquid. an intermediate regenerator (3) that heats the dilute absorption liquid that has absorbed the refrigerant in the absorber (2) to evaporate the refrigerant; and an intermediate regenerator (3) that evaporates the refrigerant. an intermediate absorber a (4) that absorbs the refrigerant into an absorption liquid; a regenerator (5) that heats the dilute absorption liquid that has absorbed the refrigerant in the intermediate absorber (4) to evaporate the refrigerant; and a regenerator. It consists of a condenser (6) that cools and condenses the refrigerant evaporated in step (5). Note that (7) and (8) are installed in the middle of the movement path of the absorption liquid on the low-pressure side and the high-pressure side, respectively.
