Study on Energy Consumption of Secondary Water Supply System in Typical Old Residential Quarters in Shanghai under the Background of "Double Carbon"

  • 摘要: 通过对上海典型老旧居民小区的多层建筑和高层建筑供水系统进行研究,对比分析了二次供水水泵在不同工况下的水量、能耗及效率方面的差异。结果表明,由于水池+变频水泵模式下,水泵一天内主要时段的供水水量远低于额定流量,因此在满足相同供水需求情况时,其运行效率是水池+工频水泵+屋顶水箱模式下的约50%。但部分水箱存在因位置距离顶层居民过近仅凭重力流无法满足供水压力需求的情况,水池+工频水泵+屋顶水箱模式需要再次加压,且屋顶水泵再次加压的能耗约为泵房变频水泵能耗的200%以上,此时相较之下水池+变频水泵模式下总体能耗更低。
