摘要

通过计算流体动力学(CFD)仿真与实验结合的方法,探索10种不同的运行策略对墙体热性能的影响,并基于夏热冬冷地区典型气象年参数开展长期运行研究。结果显示:当控制温度阈值的上限和下限分别为 27 ℃和25 ℃时,即为该文得出的最优控制方案;在该控制方案下,嵌管式可移动相变墙体夏季的室内累计得热量比两种静态相变墙体分别减少10.6%、10.8%,相较于静态相变墙体和普通墙体具有良好的节能效益。

Abstract

The effects of 10 different operational strategies on the thermal performance of the wall are explored by combining CFD simulation and experiment, and a long-term operation study is carried out based on the typical meteorological annual parameters in hot summer and cold winter regions. The results show that the optimal control scheme derived in this paper is when the upper and lower control temperature thresholds are 27 ℃ and 25 ℃, respectively; under this control scheme, the cumulative indoor heat gain of the embedded pipe-type movable phase change wall in summer is reduced by 10.6% and 10.8%, respectively, compared with the two types of static phase change walls, which provides good energy-saving benefits compared with the static phase change wall and the ordinary wall.
