PROBLEM TO BE SOLVED: To provide an absorption refrigerating machine which can be stably operated even if temperature of cooling water is low.SOLUTION: The absorption refrigerating machine 100 is provided with: a flow passage resistance unit 41 including a high-temperature regenerator 5, a low-temperature regenerator 6, an evaporator 1, a condenser 7, and an absorber 2, connecting the high-temperature regenerator 5 and the condenser 7 by a refrigerant pipe 31 which goes through the low-temperature regenerator 6, and giving flow passage resistance to the refrigerant pipe 31; and a bypass pipe 42 for bypassing the flow passage resistance unit 41. The bypass pipe 42 is provided with an opening/closing valve 43. The absorption refrigerating machine 100 includes a cooling water pipe 15 for circulating the cooling water serially in the absorber 2 and the condenser 7, a cooling water temperature sensor 62 for measuring temperature of the cooling water on an absorber inlet side of the cooling water pipe 15, and a valve controller 50 for controlling the opening/closing valve 43 according to a measurement result of the cooling water temperature sensor 62. |
