とが具備されている。As shown in Fig. 1, this absorption heat source device evaporates a refrigerant and introduces a heat medium (e.g., water) from an indoor unit (not shown) to exchange heat between the two. The evaporator 1 to be cooled and the refrigerant vapor evaporated in the evaporator 1 are introduced through a communication section (for example, a communication pipe) 11 to absorb an absorption liquid (for example, lithium bromide is used, and to improve its absorption efficiency). an absorber 2 that absorbs the refrigerant vapor into a liquid (to which a surfactant is added to increase
, a gas-liquid separator 4 that separates refrigerant vapor and surfactant vapor from the gas-liquid mixed liquid heated by the regenerator 3, and a gas-liquid separator 4 that condenses the refrigerant vapor separated by the gas-liquid separator 4. An air-cooled condenser 5, a concentrated absorption liquid transfer pipe 12 that sends the concentrated absorption liquid that has been separated from the refrigerant vapor and surfactant vapor in the gas-liquid separator 4 to the absorber 2, and A diluted absorption liquid transfer pipe 14 having a pump 13 and sending the diluted diluted absorption liquid in the absorber 2 to the regenerator 3; A refrigerant vapor transfer pipe 15 for transferring to the condenser 5 side, and a heat transfer pipe 16 provided in the middle of the refrigerant vapor transfer pipe 15 and interposed in the middle of the dilute absorption liquid transfer pipe 14 are provided to transfer the refrigerant vapor together with the refrigerant vapor. A surfactant condenser 17 that condenses the vapor of the evaporated surfactant, and a refrigerant liquid transfer pipe 19 that has a refrigerant pump 18 in the middle and that transfers the refrigerant liquid condensed in the condenser 5 to the absorber 2. Then, the surfactant condensed in the surfactant condenser 17 is transferred to the concentrated absorption liquid absorption tube 12.
A surfactant return pipe 20 is provided between the concentrated absorption liquid transfer pipe 12 and the dilute absorption liquid transfer pipe 14 to recover the heat by giving the heat of the concentrated absorption liquid to the dilute absorption liquid. exchanger 21
It is equipped with.

ている。The heat exchanger 21 is located upstream of the connection point of the surfactant return pipe 20, and the connection point of the surfactant return pipe 20 to the concentrated absorption liquid transfer pipe 12 is a heat exchanger. The temperature is relatively low downstream of the vessel 21.

面活性剤が添加された吸収液に効率良く吸収される。冷
媒蒸気を吸収して濃度が薄くなった稀吸収液は再生器３
に導かれて加熱される。For example, when a cooling operation is performed with the above configuration, the refrigerant vapor evaporated in the evaporator 1 is guided to the absorber 2, where it is efficiently absorbed by the absorption liquid to which a surfactant has been added. The diluted absorption liquid whose concentration has become diluted by absorbing refrigerant vapor is sent to regenerator 3.

される。この界面活性剤凝縮器１７では、第２図に示す
ように、冷媒すなわち水の凝縮温度Ｃ点よりも高い温度
Ｂ点で凝縮させるようにしているため、この時の界面活
性剤の濃度はＡ点となり、水の濃度は非常に薄くなる。Note that in this regenerator 3, since the surfactant is also heated, surfactant vapor is also generated together with the refrigerant vapor. Therefore, the refrigerant vapor separated by the gas-liquid separator 4 also contains surfactant vapor, and these vapors are led into the surfactant condenser 17 where they are cooled by the dilute absorption liquid. Ru. In this surfactant condenser 17, as shown in FIG. 2, since the refrigerant, that is, water, is condensed at a temperature point B higher than the condensation temperature point C, the concentration of the surfactant at this time is A. It becomes a point, and the concentration of water becomes very thin.
したがって、界面活性剤の濃度が濃い状態となり、界面
活性剤の回収を充分に行うことができる。Therefore, the concentration of the surfactant becomes high, and the surfactant can be sufficiently recovered.

２途中に混入されて循環使用される。Then, the refrigerant vapor from which the surfactant has been removed enters the condenser 5, where it is condensed to become a refrigerant liquid, and the refrigerant liquid transfer pipe 1
It is circulated and transferred to the evaporator 1 via the evaporator 9. On the other hand, the surfactant condensed in the surfactant condenser 17 is transferred from the gas-liquid separator 4 to the concentrated absorption liquid transfer pipe 1 via the surfactant return pipe 20.
2. It is mixed in the middle and used cyclically.
このように、界面活性剤が界面活性剤凝縮器１７で回収
されるため、運転につれて界面活性剤が室内機との熱交
換用の熱媒に混入するのを防止することができるととも
に、界面活性剤の濃度が薄くなるのを防止することがで
きる。In this way, since the surfactant is recovered in the surfactant condenser 17, it is possible to prevent the surfactant from being mixed into the heating medium for heat exchange with the indoor unit during operation, and also to prevent the surfactant from being mixed into the heating medium for heat exchange with the indoor unit. It is possible to prevent the concentration of the agent from becoming diluted.
また、濃吸収液からの稀吸収液への熱回収は界面活性剤
凝縮器１７内を出た後で行われて、いるため、界面活性
剤の凝縮熱も無駄にならず、したがって設備全体の熱効
率を向上させることができる。In addition, since the heat recovery from the concentrated absorption liquid to the diluted absorption liquid is carried out after leaving the surfactant condenser 17, the condensation heat of the surfactant is not wasted, and therefore the entire equipment is Thermal efficiency can be improved.
ところで、上記実施例においては、室内機からの熱媒を

設けられる。Incidentally, in the above embodiment, a case has been described in which the heat medium from the indoor unit is directly cooled, but for example, as shown by the broken line in FIG. When the heat medium from the heat exchanger is guided into the heat transfer tube 31 and cooled indirectly, the surfactant condenser 17 is not necessary because the surfactant does not mix into the heat medium side. However, in this case, since the refrigerant liquid accumulated in the evaporator 1 is mixed with a surfactant, the refrigerant liquid return pipe 32 for returning the refrigerant liquid in the evaporator 1 to the concentrated absorption liquid transfer pipe 12 is required. provided.

A dilute absorption liquid transfer pipe, a refrigerant vapor transfer pipe that transfers the refrigerant vapor separated by the gas-liquid separator to the condenser, and a refrigerant liquid transfer pipe that transfers the refrigerant liquid condensed in the condenser to the absorber. In the absorption heat source device, a refrigerant liquid return pipe is provided to transfer the refrigerant liquid accumulated in the evaporator to the concentrated absorption liquid transfer pipe, and the surfactant added to the absorption liquid is transferred to the absorber side. An absorption type heat source device characterized in that it returns to .
