(C) Problems to be solved by the invention Conventionally, in order to discharge the non-condensable gas of each absorber of the absorption refrigerator disclosed in Japanese Utility Model Publication No. 52-51317, for example, the above-mentioned JP-A-60-240972. The non-condensable gas discharge device disclosed in the publication is provided in the absorption refrigerator, and the extraction chamber of the non-condensed gas discharge device is connected to each absorber of the absorption refrigerator by piping. In the case of such pipe connection, when the noncondensable gas enters from the outside into one of the absorbers and the pressure of the noncondensable gas becomes high, the noncondensable gas is extracted into the extraction chamber only from the one absorber. The non-condensable gas is not drawn from the other absorber. Then, the pressure of the non-condensable gas in the other absorber is increased, the refrigerant absorption capacity is reduced, and the coefficient of performance of the absorption refrigerator is reduced. In order to solve the above problems, when a large amount of noncondensable gas enters one of the absorbers when the noncondensable gas discharge device is connected to each absorber, the noncondensable gas of the other absorber is removed. It can be discharged by another non-condensable gas discharge device. However, when the amount of noncondensable gas that has entered one of the absorbers is large and the container is filled with the noncondensable gas, the liquid seal between the container and the one absorber disappears, and the noncondensable gas flows from the container to the other side. There is a possibility that the refrigerant may flow to the absorber and the refrigerant absorption capacity may further decrease.

The present invention stably extracts non-condensable gas from a plurality of absorbers, and returns the extracted non-condensable gas to the absorber even when a large amount of non-condensable gas is generated in any of the absorbers. The purpose is to prevent.

(E) Action The non-condensable gas tanks (46), (44) differ in the amount of non-condensable gas generated in the absorbers (3), (4) during operation of the absorption refrigerator.
When a difference occurs in the amount of non-condensable gas extracted into the tank and a pressure difference occurs in each non-condensable gas tank (46), (44), the condensed gas is discharged through the pressure equalizing pipes (A), (B). The non-condensable gas can be stored in the non-condensable gas tanks (46) and (44) almost equally without flowing the pressure difference, and the extraction of the non-condensable gas can be stabilized. Further, for example, when a large amount of non-condensable gas is generated in the absorber (3) and a large amount is extracted in the non-condensable gas tank (46), the non-condensable gas is passed through the pressure equalizing pipes (A) and (B). It is possible to prevent the non-condensable gas tank (46) from flowing to the non-condensable gas tank (46) and to keep the liquid seal by preventing the non-condensable gas tank (46) from being filled. It will be possible.

Further, the amount of non-condensable gas generated in the absorbers (3), (4) or the condenser (8) is different, and the non-condensable gas extracted to the ejectors (49), (47), and (48) is different. When the amount is different and the pressure of the non-condensable gas in the storage chambers (60), (58), and (59) is different, the non-condensable gas is equalized in the pressure equalizing pipes (A) and (B).
It becomes possible to stabilize the extraction of the non-condensed gas by making the amount of storage in each storage chamber substantially equal to each other by flowing through In addition, when a large amount of non-condensable gas is generated in any of the absorbers (3), (4) or the condenser (8) and the extraction amount of any of the ejectors is significantly increased, the non-condensable gas is also increased. Flows through the pressure equalizing pipes (A) and (B) and is dispersed into each storage chamber, and one of the storage chambers is filled with the non-condensable gas to prevent the non-condensed gas from returning to the evaporative absorption cylinder (1). In addition, the ejectors (49), (47), and (48) can stably extract air.

Further, when a leak occurs in the evaporation / absorption cylinder (1) and, for example, the amount of noncondensable gas in the absorber (3) rapidly increases, the extraction amount of noncondensable gas by the ejector (49) rapidly increases. Then, when the non-condensable gas in the storage chamber (60) increases and the pressure becomes higher than that of the other storage chambers (58), (59), the non-condensed gas is discharged from the storage chamber (60) into the pressure equalizing pipes (A), (B). ) To the other storage chambers (58) and (59). Therefore, the non-condensable gas that has rapidly increased in the non-condensable gas tank (46) is dispersed in the other non-condensable gas tanks (44) and (45), and the non-condensable gas is absorbed through the absorbent return pipe (77). There is no such thing as (3).

In addition, for example, when two evaporators are provided in the evaporation absorber cylinder (1) and absorbers are provided on both sides of each evaporator, a non-condensable gas tank is pipe-connected to each absorber and each non-condensable gas tank is connected. Similar effects can be obtained by connecting the pipes with a pressure equalizing pipe.

(G) Effect of the present invention The present invention is an extraction device for an absorption refrigerating machine configured as described above, and a non-condensing gas tank is connected to each of a plurality of absorbers, and a pressure equalizing pipe is connected between the non-condensing gas tanks by piping. Therefore, if there is a difference in the extraction amount of each non-condensable gas tank, the non-condensable gas flows between the non-condensable gas tanks via the pressure equalizing pipe, the non-condensable gas storage volume becomes almost equal, and each absorber The non-condensed gas can be stably extracted from the
Even when the non-condensable gas rapidly increases in any of the absorbers, the extracted non-condensable gas is dispersed into each non-condensable gas tank through the pressure equalizing pipe, and the non-condensable gas can be prevented from returning to the absorber. As a result, it is possible to avoid a large decrease in the refrigerant absorption capacity of the absorber and prevent a large decrease in the coefficient of performance.

Further, ejectors are connected to the plurality of absorbers and condensers of the evaporation and absorption cylinder by piping, and a plurality of tanks for storing the non-condensable gas extracted by these ejectors are provided, and a pressure equalizing pipe is provided between the plurality of tanks. Since the pipes are connected, if there is a difference in the extraction amount of non-condensable gas from each ejector, and if there is a difference in the amount of non-condensable gas flowing to each tank, then non-condensation will occur between each tank via a pressure equalizing pipe. The gas flows, and as a result, non-condensable gas can be stored in each tank almost equally.
The bleeding capacity of each ejector can be stabilized, and the amount of non-condensed gas in either absorber or condenser increases sharply,
Even if the amount of uncondensed gas extracted from one of the ejectors suddenly increases, the rapidly increasing noncondensable gas is dispersed to each tank through the pressure equalizing pipe, preventing the noncondensable gas from returning from the tank to the inside of the evaporation absorber. As a result, it is possible to avoid a large decrease in the coefficient of performance.
