全要素气候模拟实验舱在风驱雨湿热过程研究中的应用

Application of all-element climate simulation experimental cabin in study of wind-driven rain,humidity and heat processes

实验法是研究风驱雨湿热过程的主要方法之一。气候模拟实验舱测量法能够解决现场实测法周期长和风洞试验法传热模型尺寸不足的问题,但目前能够运用这种方法的平台相对较少。为研究风驱雨对建筑围护结构湿热过程的影响,搭建了可模拟太阳辐射、风、雨等自然界综合气候环境条件的全要素气候模拟实验舱,对其进行热湿传递稳态和动态实验模拟测试,并进行实验应用。测试结果表明,该模拟实验舱稳定性好,模拟精度高,可实现对室外气象环境复现。

The experimental method is one of the main methods for studying wind-driven rain,humidity and heat processes.The climate simulation chamber measurement method can solve the problems of the long period of the field measurement method and the insufficient size of the heat transfer model of the wind tunnel test method,but at present there are relatively few platforms that can apply this method.In order to study the effect of wind-driven rain on the hygrothermal process of the building envelope,an all-factor climate simulation chamber,which can simulate solar radiation,wind and rain and other natural comprehensive climate conditions,is built and tested for steady-state and dynamic experimental simulation of heat and humidity transfer,and then experimentally applied.The test results show that the simulation chamber has good stability and high simulation accuracy,and can achieve the reproduction of outdoor weather environment.
