PROBLEM TO BE SOLVED: To provide an absorption refrigerating machine, having a double generator system driven under a condition that a heat source temperature is low and facilitated in the circulating flow rate control of solution. SOLUTION: Comparatively low-temperature heat is supplied to a high-pressure regenerator HG and a low-pressure reclaimer LG from a heat source via high- temperature heat pipelines HW1, HW2. Solution, condensed in the high-pressure reclaimer HG, is introduced into the low-pressure reclaimer LG via a solution pipeline S1. The solution, introduced into the low-pressure regenerator LG, is heated and condensed, and hen refrigerant vapor having a saturated vapor pressure is separated. The condensed solution, introduced into a low-pressure absorber LA through a solution pipeline S4 and a solution heat exchanger E, is dripped by a solution dripping device D1 and is turned into a diluted solution after being diluted by absorbing the refrigerant vapor. The diluted solution, cooled by cooling water, is guided into a high-pressure absorber HA through a solution pipeline S2. Here, the diluted solution is dripped into the high-pressure absorber HA by a solution dripping device D2 and is diluted by absorbing refrigerant vapor produced in the low-pressure regenerator LG, and then is returned into the high-pressure regenerator HG through a solution pipeline S3.
