| 摘 要： | 通过调湿材料内部热湿耦合方程周期性条件下的理论分析,获得封闭空间内板状调湿材料的吸放湿特性,发现封闭空间的空气含湿比的振幅与温度振幅的比值为一常数.在此基础上,提出用封闭空箱热扰动法来测量和评价材料的调湿性能.该方法简单易行,能直接体现建筑气候周期性热湿作用下材料调湿性状.

| Abstract: | Based on the internal heat and moisture transfer coupling equations for the humidity-controlled material,the analytical solutions are obtained under the steady periodic conditions,then the moisture desorption and adsorption properties of humidity-controlled material in a closed space are investigated.It shows that the air humidity ratio in the closed space changes periodically in consistent with the air temperature.The ratio of the absolute humidity amplitude to the air temperature amplitude is a constant,which can be taken as a criterion to evaluate the humidity control performance of the material.A simple method,namely,the close box and heat impulse method is put forward to measure the constant value. |
