校园供水系统改造措施与节能效果分析

Reconstructive Measures of Campus Water Supply System and Analysis of Its Energy-saving Effect

为了降低校园供水系统的电耗,在分析校园用水特点以及供水系统节能潜力的基础上,提出节能改造的措施并对节能效果进行了分析。基于充分利用水厂管网余压的考虑,提出一次直接供水与二次供水相结合的改造方案,并且提出在二次供水时充分利用管网余压的方法。现场实测和分析结果表明,改造后的供水能耗可比改造前降低50%,节能效果明显。

To reduce the electricity consumption of the water supply system in campus, the reconstructive measures to economize energy consumption were presented and the energy-saving effect was analyzed on the basis of the characteristics of the campus water consumption and the energy-saving possibilities of the water supply system. In view of adequately using the remaining pressure of piping system, a reconstructive scheme of combining primary direct water supply and secondary water supply was put forward, and a method of adequately using the remaining pressure of piping system during the secondary water supply was presented. The site practical measure and analysis result show that the energy consumption after the reconstruction can be reduced by 50% compared to that before the reconstruction, with a remarkable benefit of energy-saving.
