摘要:
针对目前传统并联供水方式各分区供水规模较小、无法实现压力层级利用等局限性，对串联叠压供水方式在高层住宅中的应用进行研究，对其工作原理进行了论述，从设计秒流量、配泵轴功率、叠压节能角度对供水方式的节能原因进行理论分析。结合工程案例，利用数解法计算两种供水方式的全天累计能耗并对比，结果表明该案例下串联叠压供水方式相较传统并联供水方式节能率为5.75%，从节能角度为高层住宅供水方式的选择提供一定参考。
Abstract:
At present, the traditional parallel water supply mode has some limitations, such as the small scale of water supply in each sub-zone and the inability to realize the utilization of pressure levels. Alternatively, the application of the series superimposed water supply method in high-rise residential buildings is worth of studying. In this work, the principle of the series superimposed water supply method is discussed. From the perspective of design second flow rate, pump shaft power, and superimposed pressure, the energy-saving factors of the water supply method are analyzed theoretically. Combined with an engineering case, the whole day cumulative energy consumption of the two water supply modes is calculated and compared by using the numerical method. Compared with the traditional parallel water supply method, the energy saving rate of the series superimposed water supply method in this case is 5.75%. From the perspective of energy-saving, this work provides a certain reference for the selection of the water supply methods in high-rise residential buildings.
