摘　　要：为了探究夏热冬冷地区太阳能热水器供暖改造的可行性,通过现场调研的方法对761个住户展开调查,掌握夏热冬冷地区供暖现状和太阳能热水器的应用现状,依据调研数据对太阳能热水器供暖改造的节能量和CO_(2)减排量进行计算,并对单户住宅系统改造的节能性和经济性进行分析。结果表明:太阳能热水器供暖改造的节能量和CO_(2)减排量分别为517亿MJ和590万t;6 m^(2)的太阳能热水器应用于供暖改造节能率可达32.6%,增加初投资的回收期仅为2.7 a。表明在该地区利用太阳能热水器进行供暖具有一定的基础条件和前景。In order to assess the feasibility of solar water heater heating renovation in hot-summer and cold-winter areas,761 households were investigated by field investigation method,and the pre-sent situation of heating and the application status of solar water heater in this area was mastered.According to the research data,the energy saving and CO_(2)emission reduction of solar water heater heating renovation are calculated,and the energy saving and economy of single-family residential system renovation are analyzed.The results show that the energy saving and CO_(2)emission reduction of solar water heater are 51.7 billion MJ and 5.9 million t,respectively.The energy saving rate of the 6 m^(2)solar water heater applied to the heating renovation can reach 32.6%,and the payback period of the initial investment is only 2.7 a.It shows that there are certain basic conditions and prospects for solar water heater heating in this area.
