摘要
分析相变材料的特点和相变墙体传热理论研究与应用现状,指出相变墙体材料的研制方向。对不同构造相变墙体建立了传热理论模型,采用显热容法运用数值模拟方法模拟了在周期性变化的室外边界条件下,相变储能墙体内的传热过程及墙体内表面的温度变化。计算结果表明:储能墙体中的相变材料层是影响墙体传热的重要因素之一。
This paper analyzes the characteristics of the phase change material and phase change wall heat transfer theory and research status.Points out the development direction of phase change walling materials.The theoretical model of heat transfer in different phase change wall was established.The change of temperature and heat transfer process in the storage wall is simulated by using numerical simulation method under the periodically changing boundary conditions.The calculation results show that the phase change material layer is one of the important factors that affect the heat transfer in the wall.
