The software was designed, using a visual basic 6.0 (C++) programming language, to perform a thermal analysis for all the rooms of the floors in the building. The developed software called AIRCCAD is implemented to handle mathematical equations and engineering calculations efficiently and effectively and provide more accurate information at the very shortest possible time than manually calculated design.enDesign,Auto-Cad,Software,Air-conditioningArticle
