operating back pressure
解釋
工作背壓-
The paper analyzes the non - lineal relations of the quantity of heat exchange and water flux of coil exchanger in part - load operating condition, the shortage of deciding the water flux in bypass pipe, the disadvantage that the operating condition of pumps and chiller ca n ' t be met with the load change of the air conditioning system in different operating condition of using pressure - difference bypassing control in primary water pump system. using load control method in the change of the operating condition of primary water pump system can realize that the load change is small and reasonable in the on / off condition of pumps and m m chiller by comparing load control method in primary variable - flow water pump system with pressure - difference bypassing control method, back water temperature control method
本論文從目前空調工程中使用的變流量水系統入手，研究了盤管換熱器在部分負荷下水流量與換熱量的非線性關系，分析了文獻中介紹的旁通管通流能力選擇的不足之處和一次泵水系統採用壓差旁通控制時，工況轉換不能滿足系統控制要求的缺陷；比較了一次泵變流量水系統中壓差旁通控製法、回水溫度控製法、負荷控製法的精確性，並得出了在一次泵水系統的工況轉換時，採用負荷控製法能使冷水機組及其相應水泵在啟停時的負荷變化范圍較小，更符合建築物的冷量需求，節能效果較好的結論。 -
