Abstract

Ever since the birth of the first air conditioner (Carrier air conditioner) in 1902, over one hundred years ago, it has been accompanied by several technical problems, e.g., (1) low energy efficiency in large open spaces, (2) spread of pollutants, airborne pandemic transmission (e.g., severe acute respiratory syndrome [SARS], COVID-19) through air-conditioning systems, and (3) low comfort caused by fan noise and blowing sounds. Here, we report a personalized pure radiant cooling device that decouples the fresh air supply from space cooling to achieve air conditioning without conditioning the air. Condensation-free radiant cooling with a radiant cooling capacity of 152 W/m2 is achieved with a polyethylene (PE) film-covered super-cold infrared-emissive surface. By optimizing the design and operation parameters, the device saves up to 50.4% of cooling energy in a typical summer building environment. Our concept opens up the possibility of pandemic-free personalized thermal management with high energy efficiency and thermal comfort.

无需调节空气即可实现 "空调 "的纯辐射冷却装置
自 1902 年第一台空调(开利空调)诞生以来,一百多年来,空调一直伴随着一些技术问题,例如:(1)大型开放空间能效低;(2)污染物通过空调系统传播,空气传播流行病(如严重急性呼吸系统综合征 [SARS]、COVID-19);(3)风扇噪音和吹风声导致舒适度低。在此,我们报告了一种个性化的纯辐射冷却装置,它将新风供应与空间冷却分离开来,在不调节空气的情况下实现空气调节。通过聚乙烯(PE)薄膜覆盖的超冷红外辐射表面实现了无结露辐射制冷,辐射制冷量为 152 W/m2。通过优化设计和运行参数,该设备在典型的夏季建筑环境中可节省高达 50.4% 的冷却能源。我们的概念为实现无大流行病的个性化热管理、高能效和热舒适性提供了可能。
