As seen in the official gazette and Japanese Patent Publication No. 46-37074,
Connect the body of the absorber or condenser and the exhaust pump with a bleed passage with a valve to continuously operate the absorption chiller or until the pressure in the body reaches the upper limit and then drops to the set value. It is known that the exhaust pump is operated and the valve is opened to discharge the non-condensed gas to the outside of the machine.

外へ排出しやすい利点がある。(C) Problems to be Solved by the Invention In an absorption refrigerating machine, during operation, non-condensable gas accompanies the flow of the refrigerant vapor and collects on the condenser or absorber side. According to this, there is an advantage that the non-condensable gas can be easily discharged to the outside of the machine.
しかし、吸収冷凍機の運転中に排気ポンプを稼働し続

ガスが十分に排出されていないことを示している。Also, during the operation of the absorption refrigerator, until the pressure inside the body reaches the set upper limit and drops to another set value,
In the conventional device that operates the exhaust pump, the non-condensable gas can be satisfactorily discharged in the initial stage of the pump operation, but there is a problem that the non-condensable gas in the body trunk cannot be sufficiently discharged after a certain period of time. Was confirmed by experiments. According to the experiment, when the exhaust pump is turned on again immediately after stopping the supply of the cooling water to the absorber and the condenser and stopping the operation of the absorption refrigerator, a large amount of non-condensable gas is discharged from the body. I found out. This experimental result shows that in the conventional device that operates the exhaust pump during the operation of the absorption refrigerator, the non-condensed gas in the absorber and the condenser is not sufficiently discharged compared with the increase in the power consumption of the pump. It is shown that.

In the gas discharge device, after stopping the supply of the cooling fluid to the absorber or the condenser or the refrigerant vapor to the heater of the low temperature regenerator, the valve of the extraction passage is opened for a predetermined time to operate the exhaust pump. It was done.

がある。(E) Action While the cooling fluid is being supplied to the absorber and condenser, the non-condensed gas flows in the flow of the refrigerant vapor while the absorption of the cooling vapor in the absorber and the condensation of the refrigerant vapor in the condenser continue. It reaches the outer wall of the cooler in these devices, and concentrates near the outer wall and accumulates in a large amount. On the other hand, when the supply of the cooling fluid is stopped, the above-mentioned absorption and condensation are interrupted and the flow of the refrigerant vapor is stopped, so that a large amount of the non-condensed gas concentrated near the outer wall of the cooler starts to float in the container. In addition, the device of the present invention has a function of discharging a large amount of non-condensable gas that has begun to float inside the container to the outside of the device.

At this time, the controller (C 1 ) to which the stop signal of the cooling water pump (31) has been input activates the exhaust pump (P) and opens the valve (V C ), so that cooling into the condenser (3) is performed. The non-condensable gas that has begun to be released from the vicinity of the outer wall of the heat transfer tube of the vessel (28) is discharged to the outside of the machine, and that in the tank (T) is similarly discharged to the outside of the machine.
In addition, by setting the operating time of this pump with the timer of the controller (C 1 ) according to the heat transfer area of the cooler (28) and the displacement of the exhaust pump (P), cooling is performed during operation of the absorption refrigerator. It is also possible to discharge almost the entire amount of the non-condensable gas that has concentrated and accumulated near the outer wall of the container (28) in the minimum required operating time of the exhaust pump (P).
