以温度和相对湿度为驱动势建立吸湿性墙体热湿耦合迁移数学模型,并通过权威案例验证模型。根据霉菌滋生条件,建立了基于瞬态温湿度及其持续时间的墙体内霉菌滋生风险评价方法。以红砖墙体为例,分析太阳辐射、室内空气温湿度对墙体内霉菌滋生风险的影响,并研究了我国南方各地墙体霉菌滋生风险。结果表明:太阳辐射越弱墙体内霉菌滋生风险越大,室内相对湿度升高使墙体内侧霉菌滋生风险快速增长,室内温度升高使墙体内、外侧霉菌滋生风险分别升高、降低;我国南方绝大部分地区墙体外侧存在霉菌滋生风险,总体上呈现东部比西部高、南部比北部高的趋势。

The paper is inclined to propose a dynamic mathematical model for simulating the transfer or transmission status in-situ of the thermos and moisture effects inside the multilayer hygroscopic building walls. For this purpose, we have chosen the relative humidity and temperature as the principal driving potentials of this model. In doing so, we have validated the model by means of comparing it with the international benchmark tests, and gained the results indicating that it would be possible for the model to be used to predict or forecast the transfer effects of the transient thermos and moistur...
