摘要
Ⅲ类学生宿舍为用水密集型建筑,按《建筑给水排水设计规范》(GB 50015—2003,2009年版)计算热水系统设计秒流量(qg)时,如果按全日制生活给水的淋浴器同时给水百分数来确定定时供水的淋浴器生活热水同时给水百分数,会出现热水系统储热能力和热水输出能力不匹配等问题。通过工程实例对此问题进行了讨论,提出对热水定时供水的用水密集型建筑,热水设计秒流量计算时淋浴器同时给水百分数应按照规范给出范围的上限来取值。耗热、供热及储热参数计算时均可按卫生器具用水考虑。计算储热水箱容积时,应考虑系统的热损失以及卫生器具小时用水次数与实际人数的关系。
III category student dormitory belongs to the intensive water consumption buildings. Ac cording to Code for design of building water supply and drainage （GB 500152003, 2009 edition）, there might be discordance between the heat storage and hot water transmission in hot water system, if the 24 hour shower simutaneous water supply percentage were used to determine the timing shower water supply percentage in the calculation of the hot water system design second flow rate （%）. Through practi cal engineering project, this problem was discussed about. It was proposed that hot water design second flow rate should be calculated out according to the maximum of shower water supply percentage for the in tensive water consumption building with timing hot water supply system. Heat consumption, heat supply, and heat storage should be determined by the plumbing fixture water consumptiorl. In heat storage water tank capacity calculation, the heat loss and the relationship between hourly plumbing fixture uses and prac tical quantity of resident should be taken into consideration.
