摘要
对上海某项目中的分区式太阳能热水系统进行性能分析,运用Trnsys模拟软件对系统集热效果、能耗以及出水水温进行计算。计算结果表明:该分区式太阳能热水系统可以达到56.86%太阳能保证率,56%以上时间可以保证出水水温维持在设定温度±5℃。该系统年节能费用为29 843元,实现二氧化碳减排每年17 906 kg。
A zoned solar hot water system of a project in Shanghai was analyzed. Trnsys, a kind of simulation software, was used to cal- culate the collector effect, energy consumption and the water temperature. The result showed that the solar fraction of the system can reach 56.86 % and the water temperature can keep less than 5℃ differences with the probability more than 56 %. This system can save 29 843 yuan per year, and the COz emission can be reduced 17906 kg per year.
