A NEW EXHAUST VENTILATION SYSTEM DESIGN SOFTWARE

A microsoft windows based ventilation software package is developed to reduce time-consuming andboring procedure of exhaust ventilation system design. this program assure accurate and reliable airpollution control related calculations. herein, package is tentatively named exhaust ventilation designsoftware which is developed in vb6 programming environment. most important features of exhaustventilation design software that are ignored in formerly developed packages are collector design and fandimension data calculations. automatic system balance is another feature of this package. exhaustventilation design software algorithm for design is based on two methods: balance by design (staticpressure balance) and design by blast gate. the most important section of software is a spreadsheet that isdesigned based on american conference of governmental industrial hygienists calculation sheets.exhaust ventilation design software is developed so that engineers familiar with american conferenceof governmental industrial hygienists datasheet can easily employ it for ventilation systems design.other sections include collector design section (settling chamber, cyclone, and packed tower), fangeometry and dimension data section, a unit converter section (that helps engineers to deal with units), ahood design section and a persian html help. psychometric correction is also considered in exhaustventilation design software. in exhaust ventilation design software design process, efforts are focusedon improving gui (graphical user interface) and use of programming standards in software design.reliability of software has been evaluated and results show acceptable accuracy.
