ABSORPTION REFRIGERATING MACHINE

PROBLEM TO BE SOLVED: To reduce in size or compact an absorption refrigerating machine. SOLUTION: The absorption refrigerating machine comprises an evaporator 10, an absorber 20, a high temperature regenerator 30, a low temperature regenerator 40, a condenser 50, a solution pump 72 and a refrigerant pump 71. The refrigerator also comprises a solution reservoir 22 formed at a lower part of the absorber to communicate with the solution pump and a solution tank 25 provided separately from the reservoir. Meanwhile, the refrigerating machine also comprises a refrigerant reservoir 12 communicating with the refrigerant pump at a lower part of the evaporator and a refrigerant tank 15 provided separately from the reservoir. A solution container of the solution tank is disposed lower than the reservoir part of the reservoir, and a refrigerant container of the refrigerant tank is disposed lower than the refrigerant reservoir part of the reservoir. A height from a suction port of the solution pump to the reservoir part and a height of the suction port of the refrigerant pump to the reservoir are necessary effective suction head or more of the pump.
