- 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.
