PROBLEM TO BE SOLVED: To lower a cooling water outlet temperature (that is, use-side temperature), and to lower an exhaust heat temperature in a generator. SOLUTION: In this absorption type refrigerating device, units U, U, ... respectively constituted by horizontally arranging an evaporator E and an absorber A and integrating them, are vertically stacked in several stages, a reflux flow circuit 6 is formed to reflex most part of dilute solution Ld from an outlet of the absorber A of the lowermost stage in the units U, U, ... to an upper portion of the absorber A in a state of being supercooled by an air-cooled heat exchanger H, and the reflux flow circuit 6 is provided with a junction portion 7 for joining a concentrated solution Lc from the generator G, to lower an evaporation temperature in the evaporator E at an upper stage side, and to rise an evaporation temperature in the evaporator E at a lower stage side, thus refrigerating capacity can be secured, a temperature of a heating medium (for example, discharged hot water) in the generator G is lowered, and the heating quantity in the generator G is increased.
