PROBLEM TO BE SOLVED: To enable the cooling of the product or the intermediate products obtained by a chemical plant or the like to be cooled, too, not to speak of the heating of the tower bottom, using the tower-head vapor or the like of a chemical plant as a heat source. SOLUTION: This absorption refrigerating machine is equipped with a high- temperature evaporator 7 which evaporates a refrigerant, using the tower-head vapor or the like of a chemical plant, a high-temperature absorber 11 which makes absorbing solution absorb the refrigerant vapor supplied from this high-temperature evaporator, a low-temperature evaporator 5 which cools the fluid to be cooled with the heat of evaporation of the refrigerant, a low-temperature absorber 9 which makes the absorbing solution absorb the refrigerant vapor supplied from this low-temperature evaporator, a regenerator 1 which heats the absorbing solution supplied from the high- temperature and low-temperature absorbers with the vapor of the tower head or the like and evaporates and separates the refrigerant and supplies the absorbing solution where the refrigerant is in low concentration to the high-temperature and low- temperature absorbers, and a condenser 3 which cools and condenses the refrigerant vapor supplied from this regenerator and supplies it to the high-temperature and low-temperature evaporators.
