(57) [Object] To provide an absorption refrigerator capable of reducing the filling amount when using an absorption solution using lithium nitrate as an absorbent and ammonia as a refrigerant. An evaporator (1) for evaporating ammonia as a refrigerant, an absorber (2) for absorbing ammonia vapor evaporated in the evaporator (1) into an absorbing solution, and a concentrated solution absorbing ammonia in the absorber (2). And a condenser 4 for condensing the ammonia vapor separated by the regenerator 3 by heating the ammonia to separate ammonia vapor, wherein lithium nitrate is used as an absorbent for the absorbing solution. And a plate type heat exchanger is used for at least the evaporator 1, the absorber 2, and the condenser 4. |
