影响地板辐射换热能力若干因素的分析

Analysis of Certain Factors Influencing Floor Radiation Heat Transfer

影响冷暖辐射地板系统的几个重要因素有供水温度、室内设计温度、埋管管距、埋管管径和地面层材料.通过实验,利用数值模拟的方法分析在一定条件下各因素与地板表面平均温度及平均热流密度之间的关系,并总结各影响因素间的相互关系.

Water supply temperature, indoor design temperature, distance of embedded pipe, diameter of embedded pipe and material of ground floor are important factors influencing cooling and heating radia tion floor system. Through experimenting, the relations between the factors promoted above and average temperature and heat flux are analyzed by numerical simulation, and at the same time the interrelations among these factors are summarized.
