PROBLEM TO BE SOLVED: To provide an absorption type refrigerating machine capable of reducing the fill of absorbing solution upon using the same consisting of absorbent of lithium nitride and refrigerant of ammonia. SOLUTION: The absorption type refrigerating machine is equipped with an evaporator 1 for evaporating the refrigerant or ammonia, an absorbing vessel 2 for absorbing the vapor of ammonia evaporated in the evaporator 1 into absorbing solution, a reproducer 3 for heating thick solution into which ammonia is absorbed in the absorbing vessel 2 to separate ammonia and a condenser 4 for condensing the vapor of ammonia separated in the reproducer 3. In such a refrigerating machine, lithium nitride is used as the absorbent of the absorbing solution while at least the evaporator 1, the absorber 2 and the condenser 4 use a plate type heat exchanger.
