摘要： PURPOSE:To prevent a reverse flow from a dilute solution tank to a refrigerant tank and to store a predetermined quantity of refrigerant by directly coupling the tank to a dilute solution tank via a passage, and equilibrating an internal pressure of the refrigerant tank with a pressure of an evaporator in the step of concentrating solution. CONSTITUTION:A regenerator 12 heats dilute solution in which water is absorbed to absorbent liquid containing lithium bromide solution as a main ingredient and generates refrigerator vapor. An evaporator 10 communicates with a condenser 16 for condensing the vapor through a capillary tube 24, and with a refrigerant tank 18 through a valve V5. On the other hand, a dilute solution tank 21 is connected between the regenerator 12 and an air-cooled type absorber 20. A directional tube 25 having a check valve V4 is connected between the tank 18 and the tank 21. In such a structure, the tank 18 is further directly coupled to the tank 21 via a passage 25, and an internal pressure of the tank 18 is equilibrated with a pressure of the evaporator 10 in the step of concentrating the solution.
