| Abstract: | This paper first bases on the moisture absorption isotherm curve of porous material and takes partial vapor pressure and temperature as the driving forces, and then derives the simultaneous heat and moisture transfer equations of porous building envelope in the hygroscopic range, finally discusses their linearized condi- tion. The result shows that the equations are 1inear in the general change range of indoor and outdoor temperature and relative humidity. |
