Abstract :

Since more than one-third of the world's energy consumption is in building part, green buildings and sustainable architecture are new ways to cope with the environment and reduce energy consumption in their buildings. The use of Trombe wall in residential, commercial and official buildings has been reduced energy consumption and solar energy storage with phase change materials will double this effect. This has caused a paradigm shift towards green building design, and ultimately the environment will be less polluting. Therefore, in this study, the effect of natural Convection on performance has been investigated on Trombe wall with phase-change material by change of size and location of incoming and outgoing air intake dampers. This research has been conducted experimentally and numerically. َAfter construction of Trombe wall with phase-change material and empirical data collection, physical conditions are simulated in FLUENT software and experimental results have been compared with numerical solutions. The results show resized Trombe wall dampers; have been increased outlet air temperature by 16 percent. The location change of dampers at the horizontal line does not increase the effect of output air temperature. 2 percent difference between the numerical results with experimental data represents the careful work and analysis.
