Thermal performance of wax Trombe wall

Using solar energy to cover heating loads of building is a clean and unconventional way that can help reduce electricity consumption. Problems the cost environmental pollution are among most important challenges facing humanity at present time. And as used for ventilation, thus need find renewable sources has become pressing need. In this direction Trombe wall, which classical passive one ventilation technologies buildings. work three-dimensional numerical study thermal performance wall utilizing paraffin wax PCM was presented. The effect thickness studied (2, 3, 4 5 cm). A FORTRAN90 computer program built solve three-dimensional, turbulent Navier stokes equations in addition enthalpy transforming method with explicit scheme based on finite volume method. Numerical results code were validated by comparing them previous experimental good agreement noted. show 2 cm thick an optimal thickness, where percentage rates increasing air temperature over ambient day hours (10 am, 12 pm, 10 pm 7 am next day) (37.8, 19.5, 30.7, 60 69.2%) respectively, compared (33.5, 15.2, 25.9, 53.3 65.3) % respectively calculated same hours.
