摘要
空气湿度作为一个重要的室内环境参数,对室内人员的健康、热舒适感及采暖空调的能耗等具有十分重要的作用。以硅藻土原矿及3种不同施工工艺的硅藻泥为研究对象,针对实验箱内的模拟环境,得到了其在不同的温度和湿度工况下的调湿性能,并试验研究了硅藻泥耦合相变板材对环境温湿度的调控效果。结果表明,随着温度的升高,硅藻泥对环境的调湿能力有所下降,而环境湿度的增大则有利于硅藻泥的吸湿,且硅藻泥与相变材料的耦合能够使二者功能正向增加。
As an important indoor environment parameter, air humidity plays an important role in indoor health,thermal comfort and energy consumption of heating and air-conditioning. Based on diatomite and three kinds of diatom ooze with different construction techniques,the humidity control performance under different temperature and humidity conditions was obtained for the simulated environment in the experimental chamber. And a preliminary experimental study on the control of the diatom ooze coupling phase change plate to the environment temperature and humidity was carried out. The results show that the diatom ooze has a decreased ability to control the humidity as the temperature increased,while the environmental humidity is conducive to the diatom ooze moisture absorption. Besides,the coupling of the diatom ooze with the phase change plate can result in a positive increase in both functions.
