摘要
辐射供冷系统被认为是一种经济、节能、舒适性好的空调系统形式而逐渐得到研究和应用。分析了地板辐射供冷的传热机理,提出了地板辐射供冷与室内热环境模拟的数学物理模型,采用CFD软件模拟分析了地板辐射供冷的室内热环境。模拟计算了供水工况和室外温度变化对地板供冷性能的影响。研究表明:供水温度对室内温度影响较大,辐射供冷宜采用小温差大流量。
Floor radiant cooling is regarded as an air-conditioning system, which is economical, comfortable and energy-saving. This paper firstly analyzes the heat-transfer mechanism of the system and then provides numerical calculation model of indoor thermal environment. The in door environment research is conducted under the help of CFD soft and water supply and variation of outdoor temperature are simulated for the cooling system. The result implies that the temperature of water supply exerts much influence on indoor temperature and small temperature difference should be used with high flow efficiency.
