The part of an absorption refrigerator that is at the highest temperature and has a highly corrosive environment is the generator, and there has been a problem in that the non-condensing inflow further accelerates the corrosion of the generator.
本発明は前述した従来技術の問題点に鑑みてなされたも
のであり１発生器内へ不凝縮ガスの流入のしにくい吸収
冷凍機を提供するものである。The present invention has been made in view of the problems of the prior art described above, and provides an absorption refrigerator in which it is difficult for non-condensable gas to flow into one generator.

気管で接続したものである。A liquid pool is formed in the middle of the pipe that sends the diluted absorption liquid to the generator, the gas phase part of this liquid pool and the gas phase part of the generator are connected with a pressure equalizing pipe, and the liquid pool is connected to the gas phase part of the generator during the refrigeration cycle. It is connected to the gas phase section by an air pipe.

収液面へ発生器内の圧力が加わり。(E) Function In the absorption refrigerator of the present invention, the gas phase part of the liquid reservoir and the gas phase part of the generator are connected by a pressure equalizing pipe, so that the pressure inside the generator is transferred to the absorption liquid level in the liquid pool. Join.

サイクル中の気相部へ送られる。Since it has the function of maintaining a more or less constant liquid level, a predetermined amount of space can always be secured in the gas phase within the liquid pool. Furthermore, since the gas phase part of the liquid pool and the gas phase part in the refrigeration cycle are connected to the air pipe, it is possible to connect the gas phase part of the first generator to the pressure equalization pipe, the gas phase part of the liquid pool,
Then, a gas flow path can be formed in the direction of the blow pipe, and the non-condensable gas separated in the liquid pool rises to the gas phase part of the liquid pool in the middle of the gas flow path, so that the non-condensable gas is rare. Part of what is mixed in the absorption liquid as microbubbles or dissolved in the diluted absorption liquid is sent to the gas phase part in the refrigeration cycle through the air pipe.

本発明による吸収冷凍機の構成は以上であり。The structure of the absorption refrigerator according to the present invention is as described above.
以下吸収冷凍機の運転時の不凝縮ガスの流れについて説
明する。The flow of non-condensable gas during operation of the absorption refrigerator will be explained below.

集室（２５）を通った後抽気ポンプ（２７） Ｋよって
機外へ排出される。When the absorption refrigerating machine is operated, non-condensable gas generated inside the machine and non-condensable gas flowing from outside the machine gather in the absorber where the internal pressure is lowest. This non-condensable gas passes through the bleed pipe (26) and the collection chamber (25) and is then discharged to the outside of the machine by the bleed pump (27) K.
しかし、不凝縮ガスの一部は稀吸収液に微小の気泡とし

って稀吸収液温度が上昇するにつれて微小気泡として稀
吸収液中に現われてくる。However, since a part of the non-condensable gas is mixed or dissolved in the dilute absorption liquid as minute bubbles, it is sent to the liquid reservoir (28) along with the dilute absorption liquid through the dilute absorption liquid pipe (12). It will be done. At this time, a part of the non-condensable gas dissolved in the diluted absorbent appears as microbubbles in the diluted absorbent as the temperature of the diluted absorbent increases by the low-temperature and high-temperature heat exchanger (16x14). .
そして、稀吸収液中に混在する不凝縮ガスの微小気泡は
液溜り（２８）内で分離される。Then, microbubbles of non-condensable gas mixed in the dilute absorption liquid are separated within the liquid reservoir (28).
液溜め（２８）の気相部は均圧管（２９）を介して圧力
の高い高温発生器（２）の気相部と接続しており。The gas phase portion of the liquid reservoir (28) is connected to the gas phase portion of the high pressure high temperature generator (2) via a pressure equalizing pipe (29).
また圧力の低い凝縮器（４）の気相部とも接続している
。このため、前記液溜り（２８）中に分離された不凝縮

排気ポンプ（２７） Ｋよって吸収冷凍機外へ排出され
る。It is also connected to the gas phase part of the low pressure condenser (4). Therefore, the non-condensable gas separated in the liquid reservoir (28) is transferred to the condenser (4) through the air supply pipe (3) together with a part of the gas in the gas phase of the high temperature generator (2). The non-condensable gas sent to the gas phase of the condenser (4) is mixed or dissolved in the refrigerant liquid and sent to the evaporator (5). After the non-condensable gas is stored in the collection chamber (25) via the absorber (7) and the bleed pipe (26),
Exhaust pump (27) K discharges the air out of the absorption refrigerator.

てもよいのは勿論である。Note that one connection part of the air pipe [connection part with the gas phase part in the refrigeration cycle] is not only the gas phase part of the condenser (4) (the gas phase part of the low temperature generator (3), the evaporator). Gas phase part of (5), gas phase part of absorber (7) [See connection of air pipe (32)]
Of course, it may be connected to a collection tank (see connection of air supply pipe (33)) or the like.

が必要なことはいうまでもない。In addition, if the connection part of one of the air pipes cannot maintain a large pressure difference like the pipe (17), and the gas in the gas phase of the liquid reservoir (28) does not flow, it is necessary to provide a pump or ejector. Needless to say.

No part of it will flow into the generator. Therefore, it is possible to provide an absorption refrigerator in which corrosion of the first generator is suppressed as much as possible.
