摘　　要：对JB150型全玻璃真空管太阳热水器展开了全生命周期能量环境效益分析,结果表明,该型太阳热水器可在1.1a内收回产品生产能耗,相比于常用的电热水器、燃气热水器和燃煤热水器,全生命周期的总节能量分别为10.5、3.8和5.1t标准煤。与电热水器、燃气热水器和燃煤热水器相比,该型太阳热水器在寿命期内,在SO_2、NO_X、CO_2和粉尘方面都具有相当的减排效益。Life-cycle assessment on energy balance and environmental impact of the JB 150 all-glass evacuated tube solar water heater was carried out. The results demonstrated that the production energy consumption of the solar water heater can be covered within 1.1 year by its solar energy gain in Beijing. Comparison with conventional electric, natural gas and coal countergarts showed that the solar heater can save 10.5,3.8 and 5.1 tce in its life cycle. Since the energy gathered by the solar water heater is renewable energy, the solar tater heater does not generate pollutants and greenhouse gas except those during its production process. Compared with conventional heaters, the solar wtater heater has considerable environ- mental significance in terms jof emissions reduction of SO2, NOx, CO2 and particulate metters.
