To provide a double effect absorption refrigerating machine capable of obtaining superior operational properties in a wide cooling water temperature range from a high load region to a partial load region.

This double effect absorption refrigerating machine includes an evaporator 8, an absorber 1, a condenser 7, a high-temperature regenerator 5, a low-temperature regenerator 6, a solution pump 2, a first dilute solution pipe 13A for guiding a dilute solution from the absorber to the high-temperature regenerator, and a second dilute solution pipe 13B for guiding a dilute solution from the absorber to the low-temperature regenerator, and is constituted to feed the dilute solution from the absorber to the high-temperature regenerator and the low-temperature regenerator in parallel. The second dilute solution pipe for guiding the dilute solution from the absorber to the low-temperature regenerator is provided with a flow control valve (solution circulation amount control means) 12 for controlling a solution circulation amount to the low-temperature regenerator.
