摘　　要：文章从太阳能热利用的角度出发,以太阳能集热器加快速式燃气热水器的组合为系统基本配置,在不同的用水定额指标情况和上海的特定气象资料下,采用MATLAB软件进行了动态负荷计算与分析,得出逐时集热温度,并以此为基础计算燃气耗量,分析了改变集热器面积,蓄热水箱体积,系统所需要的燃气量以及相应的费用变化,从而评价出最佳配置方案。The article adopts MATLAB software to calculate and analyze solar energy collector adding fast gas water heater dynamic load from utilizing solar energy angle by different water norm index condition and special whether information in shanghai. From those calculation results can get hourly heat collecting temperature to calculate gas consumption. The paper also analyzes the needed gas amount in system and the corresponding change cost in order to evaluate the best configuration scheme when change collect area and heat storage water tank volume.
