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。
Domestic hot water system, hot water use of water standard and hourly coefficient of variation is the key design parameters. Through the actual measurement of the water consumption in Zijingang Campus of Zhejiang University, it is found that the maximum daily hot water consumption and the average daily unit water consumption of students in this school are greatly different from the current normative standards, affecting the actual selection of water supply equipment. At present, solar energy and heat pumps and other renewable energy and energy-saving equipment has been a lot of applications. Under this background, how to select and apply the average daily water consumption and daily water consumption rationally is proposed, and its rationality is analyzed in order to ensure the safety of system operation and improve the technical and economic performance of the system for the future design Provide technical reference.
