Optimal reset method of differential pressure in variable water flow system based on most unfavorable thermodynamic loop

提出了空调水系统最不利热力环路和最大阀位环路的概念,给出了基于空调水系统最大阀位环路重整化阀位域的压差重整化方法。以压差监测点设于分、集水器两侧的单级泵变流量空调水系统为例,进行了模拟分析,结果表明,与其他几种常见的变压差设定值控制方法相比,该压差重整化方法适应性强、节能效果明显。

Presents two concepts including most unfavorable thermodynamic loop and maximum valve position loop, and provides a novel differential pressure reset strategy based on resetting domain of valve position of maximum valve position loop. Applies the differential pressure reset method to a primary pump variable water flow system with differential pressure monitoring point located between water separating and collecting headers. Simulation results show the optimal reset method provides better adaptability and energy saving effect than other commonly used methods.
