PROBLEM TO BE SOLVED: To provide an absorption refrigerator for reducing working pressure, and superior in efficiency by improving a circulating passage of an absorbing solution. SOLUTION: A dilute solution La coming out of an absorber A is branched off, and one is allowed to flow in the highest temperature side regenerator G<SB>n</SB>by the whole quantity or a part of a branch quantity, and the other is allowed to flow in a low temperature side regenerator G<SB>n-1</SB>by the whole quantity or a part of a branch quantity, and is then further allowed to flow in a low temperature side regenerator G<SB>n-2</SB>. Such constitution reduces the concentration of the absorbing solution in the low temperature side regenerator G<SB>n-1</SB>, and also lowers a boiling temperature. A refrigerant vapor temperature is set low in the high temperature side regenerator G<SB>n</SB>being a heating source to the low temperature side regenerator G<SB>n-1</SB>, that is, the working pressure is set low in response to this, so that the absorption refrigerator for reducing the working pressure, and superior in operability is provided.
