PROBLEM TO BE SOLVED: To provide a triple effect absorption refrigeration machine capable of keeping pressure in a high temperature regenerator within a specified pressure range and temperature at a specified temperature or lower. SOLUTION: In a triple effect absorption refrigeration machine, a solution passage is branched after a weak solution from an absorber 2 is passed through a heated side of a low temperature heat exchanger 7, part of the solution is introduced into a low temperature regenerator 6, and the remainder is introduced into a medium temperature regenerator 5 via a heated side of a medium temperature heat exchanger 8 for condensing. Part of condensed strong solution is condensed in a high temperature regenerator via a heated side of a high temperature heat exchanger 9, and the remainder of the strong solution, together with the strong solution condensed in a high temperature regenerator 4 and passed through the heated side of the high temperature heat exchanger 9 and together with the strong solution from a low temperature regenerator 16 that has passed through the heated side of the medium temperature heat exchanger 8, is introduced into the absorber 2 via the heated side of the low temperature heat exchanger 7. The medium temperature heat exchanger 5 has an overflow weir provided in a strong solution outlet, and preferably an upstream side of the weir and the heated side of the high temperature heat exchanger 9 are connected with a passage having a regenerator pump 12.
