辐射供冷空调系统的室内热舒适性研究

Study on indoor thermal comfort of radiant cooling air conditioning system

辐射供冷空调系统是一种具有舒适性节能性的系统形式,本文详细介绍了辐射供冷空调系统的发展现状,系统构成以及优缺点。此外通过建立围护结构的传热模型,采用数值仿真软件,分析了辐射冷顶板供冷对围护结构内表面温度及室内热舒适性的影响,主要从人体垂直温差角度分析了冷顶板辐射对人体室内热舒适性的作用效果,结果表明,顶板辐射供冷使得人体头脚的垂直温差小于3℃,满足人体热舒适要求。

Radiant cooling air conditioning system is a kind of system with comfort and energy saving.This paper introduces the development status of Radiant cooling air conditioning system,composition of the system and the advantages and disadvantages of the system.In addition,by establishing the heat transfer model of the enclosure structure and using numerical simulation software,the influence of the cooling ceiling cooling on the inner surface temperature of the enclosure structure and indoor thermal comfort was analyzed.The radiation of the cold roof plate was analyzed mainly from the perspective of vertical temperature difference of the human body.The effect of thermal comfort in the human body is shown in the results.The results show that the radiation cooling of the ceiling makes the vertical temperature difference between the human head and the foot less than 3°C,which meets the thermal comfort requirements of the human body.
