摘　　要：介绍了太阳能与燃气复合户式热水系统,建立系统数学模型,通过实验测试验证了模型的正确性。以上海地区气象参数为例,对系统进行动态计算,得到全年太阳集热器的集热温度和复合系统的燃气耗量,并分析了燃气热水器最小温升对系统影响。结果表明,与单用燃气热水器相比,太阳能与燃气复合热水系统具有良好的经济性。A hybrid household water supplying system including a solar collector and gas-fired water heater was in- troduced. The mathematical model of the system was established and its validity was tested through the experiment. The temperature of the solar collector and the gas consumption of the system were obtained through the dynamic calculation based on the Shanghai meteorological parameters. The impact of the minimum temperature rise of the gas water heater was analyzed. The result showed that the hybrid system with solar and gas heater had a good economy compared to gas water heater system.
