摘要
建立了扁盒式光伏热水一体墙的理论模型,采用由软件生成的合肥地区全年气象数据对其光电光热性能和室内得热量进行数值模拟.计算结果表明,系统的光热效率一般在40%以上,光电效率一般在11%以上,与常规混凝土墙体相比,扁盒式光伏热水一体墙不仅有很好的热电收益,同时由于改变了建筑围护结构的性质,很好地改善了室内热环境,尤其在夏季和冬季,大大降低了空调负荷,起到了很好的建筑节能效果.
Based on the meteorological data of Hefei, a numerical model was built for the simulation of the electrical/thermal performance and heat gain of the solar wall integrated with flat-box PV/thermal collectors. Results show that the thermal efficiency is usually over 40 percent and that the PV conversion efficiency is usually over 11 percent. Due to the change in the characteristic of building envelop, compared with the traditional concrete wall, the solar wall integrated with flat-box PV/thermal collectors obviously improves the indoor thermal condition, especially in summer and winter, reducing the cooling and heating load noticeably, and achieving an excellent effect on energy efficiency.
