在寒冷环境中抑制辐射冷却建筑物中过冷的低辐射率内墙策略
Low-emissivity interior wall strategy for suppressing overcooling in radiatively cooled buildings in cold environments
中文简介
采用辐射冷却的建筑物可以显著降低冷却的能耗，但过冷现象也会发生在寒冷季节，这会对建筑物造成负面影响。在此，提出了一种利用低辐射率内表面来减少人类对冷壁的热量损失的策略，以抑制辐射冷却的负面过冷效应。比较实验基于两个具有内部热源和低/高发射率内表面的小尺寸盒子进行。结果表明，低辐射内表面箱体内的加热器温度高于高发射率表面，最大和平均温差分别为 2.3 °C 和 1.8 °C，表明低辐射率内表面为人体实现了辐射隔热效果。此外，还进行了大规模的建筑建模，不仅证实了过冷现象的存在，而且表明在过冷条件下应用低辐射率的内表面可以避免内部热源超过 30% 的热量损失。重要的是，我们发现寒冷季节低发射率和炎热季节高发射率的内表面可以充分挖掘建筑物被动辐射冷却的潜力，从而指导下一代节能建筑材料设计。
英文摘要（原文）
Buildings with radiative cooling can significantly reduce energy consumption for cooling, but the overcooling phenomenon also occurs in cold seasons, which causes negative effects in buildings. Herein, a strategy of using low-emissivity interior surfaces to reduce the heat loss from humans to cold walls is proposed to suppress the negative overcooling effect of radiative cooling.
