摘　　要：《建筑给水排水设计标准》(GB 50015—2019)对宿舍的给水设计秒流量计算方法进行了调整,居室内设卫生间的宿舍按用水分散型建筑采用平方根法计算给水设计秒流量,而按用水密集型建筑采用同时使用百分数计算定时集中热水供应系统的设计小时热水量。针对居室内设卫生间的宿舍,采用定时集中热水供应系统时,如何选择热水给水设计秒流量计算公式的问题,通过对比分析两个工程实例得出,居室内设卫生间的宿舍采用定时集中热水供应系统时,热水设计秒流量与设计小时热水量折算的秒流量不匹配,建议居室内设卫生间的宿舍采用定时集中热水供应系统时,按同时给水百分数法计算给水设计秒流量。Code for Design of Building Water Supply and Drainage(GB 50015-2019)adjusted the calculation method of the second flow in water supply design for dormitory.The dormitory with bathrooms in the living room uses the square root method to calculate the second flow in water supply design according to the water-dispersed building,and the hour flow of the timed centralized hot water supply system according to the water-intensive building along with the percentages.For the dormitory with bathrooms in the living room,which has the problem of how to select a calculation equation for the second flow in water supply design when a timed centralized hot water supply system is used,it’s known from the comparative and analysis of two engineering cases that the second flow in hot water design does not match that counted through hour flow,so it’s recommended that when the dormitory with bathrooms in the living room adopts a timed centralized hot water supply system,the designed second flow of water supply should be calculated according to the percentage method of simultaneous water supply.
