本発明は、運転停止時の操作を行なう制御装置

る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dual-effect absorption refrigerator having a control device for operating during shutdown.
従来の吸収冷凍機においては、運転停止時に、
溶液の結晶化を防止するために、発生器加熱源の
制御弁を閉じて冷凍機の運転を停止した後も溶液

ようになつていた。
In conventional absorption chillers, when the operation is stopped,
To prevent solution crystallization, the solution pump continues to operate even after the control valve of the generator heating source is closed and the refrigerator operation is stopped, performing dilution operation to equalize the concentration in the solution path. However, the cooling water pump continued to operate along with the solution pump, and stopped when the solution pump stopped.
ところが、通常は溶液ポンプの出力(例えば1
〜2kW)に比べ冷却水ポンプの出力は大きく
(例えば6〜10kW)、冷却水ポンプを必要以上に
運転するために動力の損失を招いた。
However, usually the output of the solution pump (for example, 1
The output of the cooling water pump was large (for example, 6 to 10 kW) compared to the conventional cooling water pump (6 to 10 kW), and operating the cooling water pump more than necessary resulted in a loss of power.
また、冷却水の通水を必要以上に行なうと、高
温発生器の内圧が低下して溶液の循環が行なわれ
にくくなり、濃度の均一化が十分なされず結晶を
招くおそれがあつた。 In addition, if the cooling water is passed more than necessary, the internal pressure of the high temperature generator decreases, making it difficult to circulate the solution, and there is a risk that the concentration will not be sufficiently uniform, leading to crystal formation.
このような支障を避けるために、冷凍機の停止

The present invention provides an evaporator, an absorber, a high temperature generator, a low temperature generator, a condenser, a solution path connecting these devices,
A refrigerant path, a solution pump provided in these paths, a refrigerant pump, a cooling water path communicating with the absorber and the condenser, a cooling water pump provided in the cooling water path, and a cold water communicating with the evaporator. A dual-effect absorption refrigeration system, comprising: a cooling water route, a cold water pump installed in the cold water route, and a timer mechanism that issues a signal to stop the operation of the cooling water pump after a predetermined set time after the chiller operation has stopped. In the refrigerator, when the load is large according to a load detector that detects the load condition before the chiller stops operating, and the load condition detected by the load detector during operation before the chiller stops operating. The device is equipped with a control mechanism that selects a predetermined set time so that the time is long and the time is short when the load is small.

る。
According to the present invention, when the absorption refrigerating machine is stopped, the cooling water pump is not immediately stopped, but is allowed to continue operating for a while depending on the load condition before stopping, thereby continuing to circulate the cooling water. The solution pump continues to operate for dilution, and the solution is circulated, but since heating in the generator has already been stopped, it is cooled by the cooling water, and the solution temperature gradually decreases, and the cooling water temperature also decreases. It gradually decreases.
冷却塔に用いられる充填材には、例えば硬質塩
化ビニール(PVC)などが用いられ、それらの
実用的な耐熱限度はおよそ60〜80℃程度である。 The filling material used in cooling towers is, for example, hard vinyl chloride (PVC), and its practical heat resistance limit is approximately 60 to 80°C.
従つて、冷凍機の運転停止後、冷却水の温度が
次第に低下し、冷却水の通水を止めて停留状態と

溶液(既に或る程度温度降下している)が降りか

は、停止時点或いはその直前の負荷の状態に関係
する。 Therefore, after the refrigerator stops operating, the temperature of the cooling water gradually decreases, and the cooling water in the cooling water tube, which stops flowing and becomes stagnant, becomes a relatively high temperature solution (already to some extent). The cooling water pump should be stopped when the temperature drops (for example, 25 to 30 degrees Celsius) or below, which does not reach the above heat resistance limit. , relates to the state of the load at or just before the stop.
即ち、停止時点において高負荷で運転している
場合には、発生器内の圧力が高く、溶液温度も高

なる。そのため、冷凍機の運転停止後、冷却水温
度が所定の許容温度にまで低下するのに要する時
間は、高負荷運転後の場合は長く、低負荷運転後
の場合は短かい。 That is, if the operation is under high load at the time of shutdown, the pressure inside the generator is high and the solution temperature is also high, so the temperature of the solution returned to the absorber is also high, and the cooling water after the shutdown is The rate of temperature drop also slows down. Therefore, the time required for the cooling water temperature to drop to a predetermined allowable temperature after the refrigerator stops operating is long after high-load operation, and short after low-load operation.

冷却水温度が所定の許容温度以下となるべき時点
以降に冷却水ポンプを停止せしめるようにする。 The load condition at or just before the stoppage (the time just before or the average from about 10 minutes before the stoppage until the stoppage) is detected by the temperature of the solution, etc., and the cooling water is turned on after a predetermined set time after the stoppage. A timer mechanism is provided to stop the pump, and the set time of this timer mechanism is selected according to the load condition detected in advance.
To stop a cooling water pump after a point in time when the cooling water temperature should become below a predetermined allowable temperature.
本発明では、このように時限機構の設定時間を

せて過ぎて希釈運転に支障を来すこともない。 In the present invention, the setting time of the timer mechanism is selected according to the load condition at or before the time of stopping, that is, the setting time is set longer after high-load operation and shorter after low-load operation, and the cooling water pump is activated. By stopping the cooling water, even if a relatively high-temperature solution (the temperature has already dropped to a certain extent) falls after the cooling water flow has stopped, the cooling water remaining in the tube will still reach the above-mentioned limit. temperature of 60 to 80℃, which prevents damage caused by thermal expansion of the tube, and even if the chiller is restarted afterwards, cooling water that has reached a sufficiently low temperature is sent to the cooling tower to prevent damage to the filling material. Never.
Moreover, there is no need to operate the cooling water pump for an unnecessarily long period of time, resulting in loss of power, or to reduce the internal pressure of the high-temperature generator too much, thereby interfering with the dilution operation.

Other load detectors that detect the heating amount of the high-temperature generator GH include a flow rate detector for the heating source fluid (steam, hot water, or fuel gas or fuel oil in the case of a direct-fired type), or a flow rate detector for the flow rate control valve. An opening detector may also be used. Further, as the load detector, a pressure detector or a temperature detector that detects the pressure or saturation temperature within the high temperature generator GH may be used. Furthermore, a temperature detector that detects the cooling water temperature related to the above temperature and pressure may be used.
