Loading PCM Into Buildings Envelope to Decrease Heat Gain-Performing Transient Thermal Analysis on Nanofluid Filled Solar System

The high share of buildings in energy consumption and carbon dioxide emission has led researchers to seek techniques reduce this sector. In study, considering a hot arid climate region, the wall’s heat gain was investigated. To demand, three adding PCM, combining absorption chiller with solar system dispersing nanoparticles were used results evaluated transiently. July, addition PCM building's walls reduced exchange between interior exterior spaces up 21%. cool spaces, combination + fan coil several flat plate collectors integrated it demand. By collecting using stratified tank, generator section by 450 kWh. Nanoparticles improve performance found that loading ZnO Al 2 O 3 is useful. Dispersing into water increased energy-saving 9.5% while second nanoparticle improved 14.5%.
