摘　　要：生活热水能耗在建筑能耗中是不可忽视的一部分,太阳能生活热水系统适宜性研究对建筑节能具有重要意义。本研究基于对太阳能生活热水系统的实测调研对系统的运行现状进行研究。建立了太阳能生活热水逐时能耗模型,并基于实测结果进行校验。模拟分析了补水策略、用户使用模式、系统形式等因素对系统的能耗影响,给出了系统适宜性分析结论。It is significant to study the adaptability of the solar domestic hot water system as it accounts for the building energy consumption in a non-negligible proportion. This study figured out the performance of the centralized solar domestic hot water system through field measurements,as well as built a sub-hourly simulation model,which has been validated with the field measurement. The model was used to analyze the influence of several factors on the energy consumption of the system,such as the water supply strategy,the use modes of occupants,and the forms of the system. The adaptability of the system was concluded.
