PROBLEM TO BE SOLVED: To prevent the enlargement of a lower barrel to keep the easiness in installation, even when a refrigerating efficiency is increased, by making the absorption liquid absorb a refrigerant several times. SOLUTION: The lower barrel 7A incorporating an evaporator 5A and an absorber 6A, and the lower barrel 7B incorporating an evaporator 5B and an absorber 6B are evenly arranged in height at a lower part of an upper barrel 4, a lower part side of a condenser 3 and the evaporator 5B are connected by a refrigerant pipe 19, lower sides of the evaporators 5A, 5B are connected by a refrigerant pipe 17, and a lower side of the evaporator 5B and diffusers 5A1, 5B1 are connected by a refrigerant pipe 20 having an refrigerant pump 10. A lower side of the absorber 6A and a diffuser 6B1 of the absorber 6B are connected by an absorption liquid pipe 13 having an absorption liquid pump 11, further a lower side of the absorber 6B and a high-temperature regenerator 1 are connected by an absorption liquid pipe 14 having an absorption liquid pump 12, a low-temperature heat exchanger 8 and a high-temperature heat exchanger 9, and a lower side of the low-temperature regenerator 2 and the diffuser 6A1 of the absorber 6A are connected by an absorption liquid pipe 16 having the low-temperature heat exchanger 8.
