摘　　要：通过典型年太阳辐照量、太阳能实测对重庆地区太阳能资源进行分析评价;根据典型年太阳能资源数据对重庆地区太阳能热水应用效果进行理论分析,并采用实验测试的方式,从集热效率、得热量、太阳能保证率等方面对重庆地区太阳能热水适宜性进行实测研究。研究表明,重庆地区太阳能资源全年太阳能资源分布极不均匀,具有明显的阶段性分布特征,水平面上太阳辐照量最大;重庆地区太阳能热水系统集热效率、得热量、太阳能保证率等均具有阶段性特征,重庆地区太阳能热水宜阶段性使用。The solar energy resource of Chongqing is analyzed through the actual measurement on yearly sunshine exposure dose and solar energy. The application effect of solar water heating in Chongqing is investigated based on the typical yearly data of solar energy, meanwhile;some experiments have been done to measure the actual application effect of the solar water heating efficiency from heat collection, solar fraction and so on. The study shows that the solar irradiation in Chongqing doesn＆#39;t keep a stable value throughout the year and the horizontal plane gets the maximum solar irradiation;the heat collecting efficiency, heat gaining and solar fraction of solar water heating system have different values in different months;the solar water heating system has a better performance in summer and transition seasons.

关 键 词：太阳能热水系统 太阳能资源 太阳能保证率 集热效率
