摘要： PROBLEM TO BE SOLVED: To provide an absorption refrigerating machine capable of obtaining a large difference between pump-up temperatures in a two-stage evaporating/absorbing cycle equipped with two sets of an evaporator and an absorber by using efficiently a heat exchanging temperature difference of the cycle. SOLUTION: The absorber is for absorbing refrigerant vapor of solution made to flow down on outer surfaces of a plurality of heat transfer tubes installed substantially perpendicularly. The evaporator is for taking absorption heat from the outer surfaces of the heat transfer tubes by making a refrigerant flow down on the inner surfaces of the heat transfer tubes. The height of a partition of a refrigerant tank of a high temperature evaporator is set lower than that of a partition of a refrigerant tank of a low temperature evaporator to make flowing resistance of the refrigerant vapor of the high temperature evaporator small, and a large difference between pump-up temperatures is obtained.

A liquid reservoir 15 is mounted at a solution outlet portion of the intermediate-temperature regenerator 11 to temporarily reserve the solution flowing out from the intermediate-temperature regenerator 11. Further a flow adjusting means is mounted for adjusting the flow of the solution sprayed to the pipe group 12 in the intermediate-temperature regenerator 11 in accordance with a height of a liquid level of the liquid reservoir 15. The flow adjusting means adjusts the solution to flow by the quantity more than that predetermined as an inflow quantity to the intermediate-temperature regenerator 11 when the height of liquid level of the liquid reservoir 15 reaches a height more than predetermined upper limit height.
