dc.description.abstract | 太陽能集熱系統結合噴射式製冷技術是一項新能源的改良方案,產生器為供應噴射式製冷系統運作的動力源,當產生器接受外部熱源時,將工作流體蒸發提供噴射器驅動製冷現象,但是同時也會減少內部的工作流體存量,所以必須藉由循環泵浦提供一個穩定的流量來供給產生器。
本研究為開發循環泵浦液位控制器,改良目前噴射式製冷系統所使用的循環泵浦,使循環泵浦更省電,同時又可以達到液位控制。因實際噴射式製冷系統過於複雜,利用一小型液位控制系統做模擬測試分析。首先對循環泵浦的性能做測試,循環泵浦在轉速2000RPM和3000RPM,工作壓差為503kPa,都可吐出0.8LPM以上的流量,足夠噴射式製冷系統中所使用,而循環泵浦耗電量都可控制在50 W以內。接著對液位系統的動態模型進行分析,找出系統的理論動態模型,並經由實驗分析得到系統的動態模型,再以PI控制器設計控制系統,根據系統不同的響應規格,求得最佳的控制參數使系統達到穩定。實驗結果顯示,循環泵浦可以準確的控制產生器的液位,在系統運轉中加入流量干擾為0.5~0.9LPM均能夠有效的抵抗,顯示所設計的液位控制器性能良好。 | zh_TW |
dc.description.abstract | Solar-collecting system with ejection-cooling technology is a meliorating project on new energy development. Generator provides power for the whole system. When generator receives external heat, it steams the working fluid which drives the cooling operation. However, this operation also reduces internal capacity of the working fluid simultaneously. Hence we use the circulator pump to provide stable flow to the generator.
This study is to develop circulator pump that controls liquid level, reform the current circulator pump on ejection-cooling system and reduce power-consuming. Owing to complicated actual ejecting-cooling system, a small liquid-control system is used for simulation experiments. First, the performance of the circulator pump is test. The result shows that while working at pressure drop 503 kPa and rotation speed from 2000 RPM to 3000 RPM, within 50 W power consumption, the circulator pump can provide the flow rate over 0.8 LPM which is enough for ejection-cooling system. Second, the dynamic model of liquid level system is analyzed to get theoretical dynamic model of liquid level system. Third, according to different condition, the optimum control parameters are used to control system stably. Based on the results of the experiments, circulator pump can accurately control liquid level of generator, and can resist external flow turbulent from 0.5 LPM to 0.9 LPM. In general, the performance of designed liquid level controller is well. | en |
