Ventilation System Design:  Theses classes are intended for persons who have systems maintenance responsibilities or who do not design ventilation systems regularly.  this class is also recommended for persons who have had limited prior experience or specific education in ventilation system design.  The problems will emphasize fundamentals of airflow in systems, and will include selection of exhaust hoods, determination of air volume and minimum duct velocity, sizing of ducts, calculation of system pressure losses, and selection of fans and air cleaning devices. 

Advanced Ventilation System Design:  Individuals selecting one of the following options should be thoroughly familiar with exhaust system design procedures or have satisfactorily completed a ventilation system design class at a prior conference. 

Nonstandard Air Designs:  This design section will deal with exhaust systems that involve elevated air temperatures and/or moisture where air density may vary significantly from standard conditions.  Such variations often occur in emission control systems, as well as product drying and cooling applications.  Air volume an pressure calculations will be made using psychrometric charts in order to determine duct sizes, fan characteristics, and adequate motor horsepower.  Alternative starting schemes to bridge standard to nonstandard conditions will be explored. 

Troubleshooting Workshop:  An optional three-hour session devoted to procedures for troubleshooting a system using the static pressure method.   This course will be offered as a separate class on Friday, February 16, 2007 for $99.00.  You do not have to register for the Ventilation Conference in order to sign up for this Workshop.
