以建筑石膏作为基体材料，将双壳微纳米相变胶囊掺入石膏基体材料中，制备相变储湿墙板，并且利用其搭建模拟房，获取自然通风条件下模拟房墙板内表面温度和相对湿度的变化，分析墙板对室内环境的调温调湿作用。结果表明，相变储湿墙板具有优良的相变性能和高效的储湿性能，作为围护结构部件，可以有效减小室内温度、相对湿度的波动范围，改善室内的热环境，提高室内环境的舒适度，达到建筑节能的目的。
With building gypsum as basis material,double-shell phase change micro-nano capsules mixed with gypsum-based,preparation of phase change and humidity storage wallboard,and use it build simulation room in order to acquire inner wall temperature and relative humidity change under natural ventilation,analysis of regu-lating temperature and humidity effects of wallboard to indoor environment.The results show phase change and humidity storage wallboard has good phase change performance and efficient humidity storage performance,as building envelope parts,it can remarkably reduce the fluctuation range of the indoor temperature and relative humidity,improve the indoor thermal environmental quality,enhance the indoor comfort and reach the aim of energy-efficient building.
