摘要

由于相变材料的高潜热含量，相变材料在包括建筑围护结构在内的许多工程应用中越来越多地用于储热和温度控制。本文对阿联酋气候条件下的PCM集成多层轻量化建筑墙体进行了数值研究。首先，给出了应用于对流和辐射边界条件下壁面组件热传导的有限体积数值方法的公式。然后，重点介绍了集成pcm在通过移峰和降量级降低冷负荷方面的作用。结果表明，在阿联酋夏季气候条件下，峰值可移动3 h，减少5.2 W/m2。

Numerical simulation of integrating PCM in multilayer wall construction in UAE

Due to their high latent heat content, phase change materials (PCMs) have gained an increasing use for thermal storage and temperature control in many engineering applications including buildings envelop. In this paper, a numerical study of a PCM integrated multilayer light weight building wall under UAE climate is examined. First, the formulation of the finite-volume numerical method as applied to heat conduction in the wall assembly under convective and radiative boundary conditions is presented. Then, the effects of integrating PCMs in reducing the cooling load by peak shifting and magnitude reduction are highlighted. The results showed that under UAE's summer climate, the peak could be shifted by three hours and reduced by 5.2 W/m2.
