PROBLEM TO BE SOLVED: To reduce a temperature and a pressure in a refrigerating cycle by reducing a margin of concentration of absorption solution in a regenerator on the most low temperature side and a regenerator on the most high temperature side. SOLUTION: In an absorption type refrigerator having the number of n (n>=3) regenerators G1 to Gn, the refrigerating cycle is constituted in such a way that (ξ1 -ξa ) and (ξn -ξa ) are smaller than (ξm -ξa ) when concentration of absorption solution Lcn after refrigerant vapor is generated in the regenerator Gn on the most high temperature side isξn ; concentration of absorption solution Lc1 after refrigerant vapor is generated in the regenerator G1 on the most low temperature side isξ1 ; concentration of absorption solution Lc flowing into an absorber A isξm ; and concentration of absorption solution Lw flowing out from the absorber A isξa . In this constitution, a temperature and a pressure in the refrigerating cycle are reduced.
