摘要
为明确气候参数、材料参数对建筑围护结构模拟结果的影响,以及热湿耦合传递模型(HM)和被普遍采用的Glaser模型之间的差异,在热湿过程模拟软件WUFI Plus中选择北美典型气候区的20个代表城市,设置15组外墙构件,进行空间单元HVAC需求、室内热湿环境和外墙热湿性能的全年模拟.模拟结果与室外气候参数进行相关性分析,表明室外气温、太阳辐射、相对湿度和风驱雨不同程度地影响相关结果.通过材料参数控制所得2组HM和3组Glaser模型的对比,表明液态水相关参数、含湿量引起的材料参数的变物性取值对模拟结果有显著影响.北美典型气候区HM模拟对我国建筑围护结构热湿过程相关的气候参数、材料参数和评估方法的研究具有借鉴意义.
To determine the impact of climate data and material parameter on building envelope simulation results,and to investigate the difference between coupled heat and moisture transfer model(HM model)and the widely used Glaser model,15 groups of exterior walls were constructed in WUFI Plus with 20 representative cities of the North America typical climate zones as external conditions,and simulated for the annual HVAC demand,indoor hygrothermal environment and the exterior walls hygrothermal performance. Correlation analyses between the simulation results and the climate parameters showed that the exterior air temperature,solar radiation,relative humidity and drying rain affected the related simulation results to varying degrees. Comparison among the 2 HM and 3 Glaser model groups distinguished with specific material parameters,showed that liquid water dependent parameters,variation of moisture content dependent heat and moisture transport properties had significant influence on the simulation results. The HM model simulation in North America typical climate zones could contribute implications to the studies on climate data,material parameters and evaluation methods for the heat and moisture process in building envelope.
