摘要
以上海市的年气象数据为计算依据,综合考虑了太阳辐照、水温、环境温度的影响,在忽略夜间损失的情况下,以天为单位,对太阳能热水系统及太阳能光伏光热系统连续加热模式下的年运行性能进行了分析计算,研究了两种系统在上海地区的应用潜力及节能特性.计算结果表明,太阳能热水系统具有较高的年平均综合效率,同时具有较短的静态回收周期;光伏光热系统一年中仅在7月、9月具有较高的综合效率.
Based on the yearly meteorological data of Shanghai, analysis and calculation of annual operation performance of solar water heating system and photovoltaic/thermal system is carried out in the case of ignoring the night loss, taking into account the effects of solar radiation, water temper- ature and ambient temperature. It is aimed at researching the application potential and energy saving characteristics of the two systems in Shanghai. The results show that solar water heating system has a high mean annual comprehensive efficiency, and has a shorter static payback period. Photovoltaic/ thermal system has a higher comprehensive efficiency only in July and September.
