本文依据我国高层旅馆高位水箱给水系统的运行规律,实际用水量变化曲线及国内外水箱容积计算方法,分析和论述了水箱生活有效容积应包括水泵运行调节用水量、高峰用水量和安全用水量三个部分的容积,并提出了两个比较完善的相应计算公式。计算结果符合实际,水箱生活水容积约为日用水量的6～11％,较近年来国内设计采用数字显著降低,接近国际先进水平。同时,本文还分析了目前我国高层旅馆消防技术水平,经计算,对水箱消防贮备水容积提出减少三分之二的可行建议。
Based on the operation law of the high water tank water supply system in China’s high-rise hotels, the actual water consumption curve and the domestic and international water tank volume calculation methods, this paper analyzes and discusses that the water tank life effective capacity should include the water pump operation regulation water consumption, peak water consumption, and safe water consumption. Part of the volume, and put forward two relatively complete corresponding calculation formula. The calculation results are in line with reality. The volume of water in the water tank is about 6-11% of the daily water consumption. Compared with recent years, the number of domestic designs has been significantly reduced and is close to the international advanced level. At the same time, this article also analyzes the current level of fire protection technology in high-rise hotels in China. After calculation, it proposes two-thirds reduction of the water storage capacity of fire tanks.
