研究了相变微胶囊掺入建筑石膏制备石膏基复合相变材料的热湿性能。通过饱和盐溶液、传热传湿模拟试验、等效导热测试等方法对石膏基复合相变材料进行性能测试,并且采用微积分和数学拟合方法对测试结果进行分析。结果表明,石膏基复合相变材料具有良好的储热含湿性能,研究首次提出石膏基复合相变材料的表面质交换系数、湿扩散系数、相变因子等重要参数,为石膏基复合相变材料的节能效果计算提供重要依据。
In order to further supplement and improve the reliability of coupled heat and moisture mathematical model in building wall,experimental research on thermal and humid property of gypsum-based composite phase change material that with building gypsum as basis material,phase change microcapsule mixed with gypsum-based.Performance of gypsum-based composite phase change material was tested by saturated salt solution, simulation experiment of heat and moisture transfer,equivalence heat conduction test,etc;and the test results were analyzed by the calculus and mathematical fitting.The results show gypsum-based composite phase change material can provide good performance of thermal storage and saturation humidity;this subj ect firstly brings up important parameters of gypsum-based composite phase change material,such as the surface mass transfer coef-ficient,moisture diffusion coefficient,phase transformation factor,etc;there parameters provides an important basis for calculating the energy saving efficiency of gypsum-based composite phase change material.
