摘要
该文以广州地区办公建筑为例,采用EnergyPlus软件比较研究了光伏薄膜玻璃窗和普通玻璃窗对房间冷负荷的影响,结果表明光伏玻璃窗对建筑节能效果显著,尤其是窗墙比较大的建筑。当窗墙比为0.7时,相比普通玻璃窗,光伏玻璃窗可使室内冷负荷减少50%。该文还研究了光伏窗空气层宽度和通风量对夏季窗户得热的影响,对于小面积光伏窗,适当增大通风通道宽度能降低室内得热;当窗户面积较大时,机械通风可以有效减少高温光伏组件对室内的传热,但通风量不宜超过0.01 m^3/(s m)。
This paper studies the effect of photovoltaic thinfilm glass windows and ordinary glass windows on the cooling load of the building by EnergyPlus,and takes the office building in Guangzhou as an example.The results show that PV windows have significant effect on building energy saving,especially the larger window-to-wall ratio.When the window-to-wall ratio is 0.7,the photovoltaic windows reduce the indoor cooling load by almost 50%compared to ordinary glass windows.The influence of the width and ventilation of the air layer on reducing the heat in the summer was further studied.For small PV windows,increasing the width of the ventilation channel properly can reduce the indoor heat.While the window area is larger,the mechanical ventilation can effectively reduce heat transfer from the high temperature photovoltaic modules,but the ventilation rate should not exceed 0.01 m^3/(s m).
