A method for the heat transfer calculation of thick-and-heavy envelope

YAN Zengfeng,LIU Jiaping(School of Architecture ,Xi'an University of Architecture & Technology, Xi'an710055,China)  
The thickandheavy dwelling building in the loess plateau is a unique residential building in the world.To study the heat transfer process of the thickandheavy envelope is a key step for simulating the indoor environment of the dwelling building with thickandheavy enclosure. It's first to combine the method of the finite element and the method of the finite difference to study the heat transfer through the thickandheavy enclosure of the dwelling building.The dynamic equations have been drawn up. A comprehensive program has been worked out based on the mathematical model, the unit dividing may be more handy by using the pretreatment program. The result of this model may be seen to support much more well the experimental conclusions. Based on the above analysis, this paper verifies the validity of the combining method of the finite element and the method of the finite difference to study the heat transfer through the thickandheavy envelope.
