摘要
为了消除太阳辐射中紫外线能量对日间冷却器的不利影响,设计了一种新型紫外吸收遮盖膜,用于日间辐射冷却器中紫外线预管理.并搭建了性能测试实验平台,相较于PE膜日间辐射冷却器,在太阳直射下添加紫外吸收遮盖膜的新型日间辐射冷却器可减少29 W/m2太阳辐射,并使温度降低1.5 ℃.且紫外线强度越高,提升效果越明显.
Abstract
To eliminate the adverse effects of UV energy in daytime radiative cooling,a new type of UV absorbing cov-er for UV pre-management was designed,which can effectively absorb UV in solar radiation and improve the cooling pow-er of the radiative cooler.The performance experimental platform was built,the cooling power of the daytime radiative cooling using UV absorbing cover can be reduced by 29 W/m2and the temperature can be lowered by 1.5 ℃ compared with that of the PE cover under direct sunlight.The performance of the daytime radiative cooling with UV absorbing cover was improved better when the UV intensity was higher.
