摘要
通过设计合理的热管理措施,使聚二甲基硅氧烷(PDMS)/铝平面制冷器的效率提高了近35％.对比了定向遮阳、移动遮阳和定向(向北)辐射对抑制太阳辐射增益的抑制效果,使用低成本辐射制冷材料实现日间辐射制冷.结果表明,在晴朗的天气下实现了 3.9～13.1 ℃的全天降温.最大制冷功率为76.8 W/m2.这种光热管理措施的结合会影响辐射制冷在建筑节能领域的应用.
Abstract
The efficiency of the polydimethylsiloxane(PDMS)/aluminum planar cooler was improved by nearly 35％through well-designed thermal management measures.Daytime radiative cooling was realized by using low-cost radiative cooling materials,through directional shading.The results show that an all-day cooling range of 3.9～13.1 ℃ is achieved under the clear weather.The maximum cooling power is 76.8 W/m2.This combination of thermal and solar management measures may affect the application of radiative cooling in the field of building energy efficiency.
