摘　　要：生活热水系统中热水用水量标准和小时变化系数是关键的设计参数。通过对浙江大学紫金港校区的用水量进行实测发现,该校学生生活热水最高日和平均日单位用水量与现行规范标准相差较大,影响实际供水设备的选型。目前,太阳能和热泵等可再生能源及节能设备得到了大量的应用。在此背景下,提出了如何合理选取和应用平均日用水量和最高日用水量的方法,并对其合理性进行分析,以期保证系统运行的安全性,提高系统技术经济性能,为以后的设计提供技术参考。Hot-water consumption criteria and hourly variation coefficient are the key design parameters of domestic hot-water supply system. The actual measurement of water consumption in a university shows that there is a significant difference between the actual maximum and average daily water consumption and the current criterion, which affects the choice of water supply equipment. At present, solar and heat pump hot-water supply system and equipment are widely used. In this context, the methods of choosing and applying rationally the average and maximum daily water consumption. The rationality of the methods is analyzed to ensures the system operation safety and improve the technical and economic per- formance, which provides a technical reference for the future design.
