期間にわたって保つことができる。Most of the non-condensable gas generated in the high-temperature generator (1) is mixed with the intermediate liquid and transferred to the low-temperature generator (4), but most of the non-condensable gas is transferred to the condenser (3) together with the refrigerant vapor. It is. Since the absorbent in the low-temperature generator (4) is heated by the refrigerant vapor in the vapor pipe (2) and the refrigerant is separated, the non-condensable gas mixed in the absorbent itself is also separated.
The amount of non-condensable gas mixed with the absorbent and transferred to the absorber is very small. The non-condensable gas conveyed into the condenser (3) is entrained in the refrigerant liquid and conveyed in the refrigerant pipe (5), but is separated from the refrigerant liquid in the gas-liquid separator (23) and separated. The non-condensable gas rises in the pipe (25) and rises in the tank (24).
Accumulate in The non-condensable gas accumulated in this tank (24)
The water is discharged out of the absorption refrigerator by the exhaust pump (26) every predetermined number of days or each time a predetermined pressure is reached. In the absorption refrigerator of the present invention, the refrigerant flowing through the refrigerant pipe (6) is compared with the conventional absorption refrigerator in which a large amount of non-condensable gas is carried to the evaporator by being mixed into the refrigerant liquid from the condenser. Since the non-condensable gas carried to the liquid is surely separated by the gas-liquid separator (23) and only the refrigerant liquid is sent to the evaporator (7), the degree of vacuum in the evaporator (7) and the absorber (12) is reduced. It can be kept in a good condition for a long time.

とができる。(G) Effects of the invention In the present invention, of the refrigerant liquid and the non-condensable gas flowing through the refrigerant liquid conduit from the condenser to the evaporator, only this non-condensable gas is separated by the gas-liquid separation device. Only the refrigerant liquid is led to the evaporator and discharged from the non-condensable gas to the outside of the absorption refrigerator.
For this reason, in the present invention, the conventional absorption method in which the pressure in the evaporator and the absorber tends to increase and the capacity of the evaporator and the absorber tends to decrease due to the non-condensable gas which is easily carried by the refrigerant liquid from the condenser. It is possible to provide an absorption refrigerator having an evaporator and an absorber whose capacity is less likely to be lower than that of a refrigerator.
