B2内の飽和蒸気圧は約５mmHgに保たれる。 The absorption liquid [lithium bromide aqueous solution] whose concentration has decreased by absorbing the refrigerant [water] while being lowered in temperature by the cooling water in the absorber 6 becomes, for example, about 35°C and accumulates in the absorption liquid reservoir 47, and is pumped by the pump 11. The liquid is then sent to the container F via the pipe a, further flows down to the first and second cooling devices D 1 and D 2 via the pipes f 1 and f 2 and returned to the absorption liquid reservoir 47 via the overflow pipe i.
The temperature of the absorption liquid that has flowed into the second cooling device D 2 is lowered to about 30°C by the cold water flowing into the second cooling coil C 2 at about 15°C, and flows down via the pipe d 2 to the second cooling coil C 2 .

る。 As mentioned above, the internal pressure of the second bleed chamber B2 is maintained approximately 65 mmHg lower than the internal pressure of the gas-liquid separation chamber A, so the refrigerant vapor containing non-condensable gas is transferred from the gas-liquid separation chamber A to the second bleed chamber B2.
Air is extracted to bleed chamber B2 . And the second bleed chamber B 2
The refrigerant vapor that flows into the is absorbed by the absorption liquid, and
The non-condensable gas flows down the pipe g 2 together with the absorption liquid.

The saturated vapor pressure in the first bleed chamber B1 is maintained at approximately 3 mmHg. On the other hand, since the internal pressure of the absorber 6 is approximately 6 mmHg, the refrigerant vapor in the absorber 6 is extracted together with the non-condensable gas through the first bleed pipe b 1 to the first bleed chamber B 1 .
Then, the refrigerant vapor that has flowed into the first bleed chamber B1 is absorbed by the absorption liquid. Further, the non-condensable gas flows down the pipe g 1 together with the absorption liquid, reaches the pipe e 1 , floats up, and is stored in the gas storage chamber E.

A cooling medium pipe is connected to the second temperature decreasing coil C2 , and a cooling medium with a temperature lower than that of cold water [for example,
A portion of the cooling water before being supplied to the absorber 6] may be made to flow. In addition, the second bleed pipe b 2 is connected to the condenser 4

Since the gas is extracted,
Unlike conventional two-stage jet bleeders, there is no need for a jet nozzle or a pump for spouting the absorption liquid into the bleed chambers D 1 and D 2 . The non-condensable gases in the air cannot be compressed above atmospheric pressure. Furthermore, when the absorption liquid pump 11 is stopped, the non-condensable gas in the gas storage chamber E does not expand several tens of times or more and flow back into the machine.
それ故、本装置は、従来の二段ジエツト抽気装
