ABSTRACT:
An absorption refrigerating machine comprising an absorber A, an evaporator E, a generator GH, GL, a condenser C, a heat exchanger XH, XL, and solution circuits 1, 2, etc. and refrigerant circuits 10, 11, etc. for connecting the elements. A concentrated solution is directed from the generators to the absorber A through a solution spray pump P.sub.3 which is provided with a controller 15 for controlling number of revolutions of the pump on the basis of a signal representative of a level of refrigerant liquid detected by a sensor 14 or concentration of solution so as to effect circulation of the refrigerant solution safely and efficiently. The absorption refrigerating machine can be a double effect absorption refrigerating machine wherein a refrigerant gas generated in a high temperature generator GH is used as a heat source of a low temperature generator GL.
