PROBLEM TO BE SOLVED: To provide an absorption-type refrigerating machine capable of stabilizing a liquid level of an absorbing liquid in a high-temperature regenerator with a simple constitution and improving coefficient of performance. SOLUTION: An absorption-type water cooler/heater 100 having the high-temperature regenerator 5, a low-temperature regenerator 6, an evaporator 1, a condenser 7 and an absorber 2, in a state of forming circulation passages of the absorbing liquid and a refrigerant by connecting them by piping, further has a liquid level sensor 52 detecting a liquid level of the absorbing liquid in an intermediate absorbing liquid reservoir 5C of the high-temperature regenerator 5, a solution regulation valve 53 disposed in an intermediate absorbing liquid pipe 22 from the high-temperature regenerator 5 to the low-temperature regenerator 6, and a control device 50 for regulating an opening of the solution regulation valve 53 on the basis of the detection level of the liquid level sensor 52.
