Title: ABSORPTION REFRIGERATOR
Abstract:
Provided is an absorption refrigerator with a configuration in which a single-effect cycle is combined with an auxiliary cycle, wherein the amount of solution retained can be reduced. An absorption refrigerator 100 comprises an evaporator 1, an absorber 9, a low-pressure regenerator 22, a high-pressure regenerator 33, an auxiliary absorber 16, an auxiliary regenerator 44, a condenser 41, and a solution pump 30. Solution piping 49 for a solution to flow from the high-pressure regenerator 33 to the absorber 9 has a junction B that is connected to solution piping 27 for a solution to flow from the low-pressure regenerator 22. The solution pump 30 is provided in the solution piping 49 from the junction B to the absorber 9. The bottom face 101 of the high-pressure regenerator 33 is disposed in a position higher than the bottom face 102 of the low-pressure regenerator 22.
