Coupled Heat and Moisture Transfer in Two Common Walls

摘要: In order to optimize building energy consumption, it is essential reduce the heat losses and gains through envelope by selecting proper materials which are often porous. However, transfer moisture highly coupled, so coupled in two common walls (aerated concrete wall red brick wall) were studied this paper. Aerated made up aerated block, cement mortar, lime–cement mortar. It widely used now for superior thermal insulation of block. Red was frequently China decades ago, many existing wall. After a simple review development models porous media, dynamic model proposed takes into account most main hydrothermal effects. temperature air humidity ratio media as critical driving potentials. Then simulate both then analyzed comparatively. Results show that can more than may accumulate cause damage easily.
