PROBLEM TO BE SOLVED: To provide a compact absorption type refrigerating device of high performance and low costs capable of more effectively utilizing exhaust heat. SOLUTION: In this absorption type refrigerating device, an indirect cooling method is applied to keep an absorbed solution supplied to an absorber A in a supercooling state by an air-cooled heat exchanger Ha in advance, a plurality of generators G, evaporators E, and absorbers A are disposed to constitute an absorption refrigerating cycle, the generators G are connected in series by a heating passage 7, the evaporators E are respectively connected in series by a cooled fluid passage 8, the refrigerant vapor of lower temperature can be generated in the generator G positioned at an outlet side of the heating passage 7, and the heating is performed by inlet exhaust heat of high temperature in the generator G connected to the evaporator E positioned at an outlet side of the cooled fluid passage 8 needing further lower evaporation temperature, when an exhaust heat utilizing system using discharged hot water as a heating medium, is applied.
