摘要
文中提出一种无盖板的双流体型光伏光热屋顶组件,通过将管板式水冷流道与折流板式空冷流道组合,降低组件水容量、提升空气出口温度,实现组件热水、热空气两种热能形式的供应.通过搭建具有稳定测试环境的性能测试试验台,研究组件工质进出口温差、光伏电池温度等随太阳辐照度、工质流量的变化情况,对组件全天热、电性能进行分析.结果表明,该组件光伏电池冷却效果明显,水冷、空冷模式下电效率最高可达16.8%、17.6%,拥有较高的全天综合性能,全天综合利用率最高为 74%.
Abstract
In this paper,a new type of bi-fluid photovoltaic/thermal roof module without cover is proposed.By combining the water-cooling duct of tube-plate with the air-cooling duct of baffle-plate,the water capacity of the component is reduced and the air outlet temperature is increased,and the supply of hot water and hot air for the module is realized.By building a performance test bench with a stable testing environment,the temperature difference between the inlet and outlet of the module and temperature of the module with solar irradiance and working fluid flow was studied,and the all-day thermal and electrical performance of the module was analyzed.The results show that the module has an obvious cooling effect.The electrical efficiency of water cooling and air cooling modes can reach up to 16.80%and 17.62%.It has high all-day comprehensive performance and the all-day primary-energy saving efficiency is up to 74%.
