摘　　要：为评估太阳能热水器对“双碳”战略的贡献,减少对化石燃料的依赖,推动能源结构的优化和转型升级,在嘉兴地区通过对全玻璃真空管型太阳能热水器在实际使用工况下进行热性能测试分析.试验结果表明:在实际使用工况下,环境温度和辐照量是影响太阳能热水器日有用得热量的重要因素;78和75管间距的年节能量分别为451.87 kWh/(m^(2)·a)、467.46 kWh/(m^(2)·a),CO_(2)年减排量分别为338.9 kg/(m^(2)·a)、350.6 kg/(m^(2)·a),经估算2021年太阳能光热利用CO_(2)减排量约占全国碳排放总量的12.6%.To evaluate the contribution of solar water heaters to the"dual carbon"strategy,reduce dependence on fossil fuels,and promote the optimization and transformation of energy structure,thermal performance testing and analysis of the actual working conditions of all-glass vacuum tube solar water heaters in Jiaxing area have been conducted.The results show that under actual working conditions,ambient temperature and irradiation are important factors affecting the daily useful heat of solar water heaters.The annual energy savings for 78 and 75 tube spacing are 451.87 kWh/(m^(2)·a)and 467.46 kWh/(m^(2)·a),respectively,and the annual CO_(2) emission reductions are 338.9 kg/(m^(2)·a)and 350.6 kg/(m^(2)·a),respectively.It is estimated that the CO_(2) emission reduction from solar thermal utilization in 2021 will account for about 12.6% of the total carbon emissions in China.
