相变材料在墙板不同位置对室内温湿度调节差异的研究

Different Influences of PCMs in Various Positions of Wallboards on Indoor Temperatures and Humidity

对相变储能墙板(使用了相变储能材料的墙板)应用的研究背景进行了简要介绍,并研究了相变储能墙板对室内温湿度的影响,重点研究了相变墙板放置不同位置产生的温湿度差异。实验结果表明,相变储能墙板可以调节室内温湿度的变化,而且相变材料在墙材中的不同组合方式对室内温湿度的调节效果也有所不同。其中相变材料位于墙体夹层中时调温效果最好,而相变材料内贴于墙体时调湿效果最好。使用相变储能墙板能明显降低室内温度,能够起到一定的建筑节能效果。

It briefly expounded the background studies of PCM wallboard （that is, the wallboards used PCM） with investigations about the influences of PCM on indoor temperature and humidity. The essential part is the different influences on indoor temperatures and humidity, when PCM posted in different positions of wallboards. The results indicate that PC, M wallboard will reduce the fluctuation of indoor temperature and humility. In addition, different places of PCM in wallboard make different effects on adjusting the indoor temperature and humility. The effect on adjusting temperature is best when PCMs are placed in the middle of the wallboards; and that on adjusting humility is best when PCMs are placed inside wallboards. Using PCM wallboard obviously reduce the indoor temperatures which contributes to building energy saving.
