Design Of Practical Passive Cooling Radiators Utilising Spectrally Selective Covers And Surfaces. Radiative cooling offers a means to cool buildings sustainably without complex and costly heat pumps or air conditioners. Units similar to solar panels can be designed with surfaces which radiate mostly into the 8 - 12 micron atmospheric window, which has a radiance much less than for other wavelengths. Commercial development has been limited by problems associated with the degradation, performance or cost of radiator surfaces. This project seeks to improve both performance and durability with innovative use of alternative materials and sputtered coatings suitable for mass manufacture, and to test the outdoor performance of laboratory produced radiative plates.

利用光谱选择性覆盖物和表面的实用被动冷却散热器的设计。辐射冷却提供了一种可持续地冷却建筑物的方法，而无需复杂且昂贵的热泵或空调。类似于太阳能电池板的单元可以设计成具有主要辐射到8 - 12微米大气窗口的表面，其辐射率比其他波长的辐射率小得多。商业开发受到与散热器表面的退化、性能或成本相关的问题的限制。该项目旨在通过创新使用适合大规模生产的替代材料和溅射涂层来提高性能和耐用性，并测试实验室生产的辐射板的户外性能。
