PROBLEM TO BE SOLVED: To control the circulation of a liquid absorbent by an inexpensive method, and operate the main body of an absorption refrigerator, even if the controller is broken. SOLUTION: In the absorption refrigerator, the circulation path, of the absorbent and a coolant is formed by connecting with pipes a high temperature regenerator 1, a low temperature regenerator 2, a condenser 3, an evaporator 4, and an absorber 5. An absorbent pipe 8 is provided from the absorber 5 to the regenerator 1. An absorbent pipe 11 with a flow control valve 12 is provided from the pipe 8 to the absorber 5. A level sensor S1 senses the level of the absorbent in the regenerator 1. When the sensed level is low, the valve travel of the valve 12 is reduced, when it is high, the valve travel is increased. The amount of inflow to the regenerator 1 is regulated, so that the level of the absorbent heated in the regenerator 1 is controlled in a certain range.
