Class Descriptions
Introductory Ventilation System Design:
This class is intended for persons who do not design ventilation systems regularly or who operate and maintain ventilation systems. It 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. This class will be taught using a computer-aided application - participants are recommended to bring a computer to class.
Nonstandard Air Design:
This design section will deal with exhaust systems that involve elevated air temperature 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 and 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.
Operations and Maintenance:
This class is a new track and focuses less on performing calculations to design sample ventilation systems and more on the hands-on application of basic ventilation system design, operation, and maintenance principles. A laboratory will be available in this class for demonstrating these various principles. Topics addressed in this class include: introductory system design principles, testing methods and system characterization, hood analysis, balancing systems with dampers/bast gates, and system analysis and troubleshooting.
Troubleshooting Workshop:
An optional 3/4-day session devoted to procedure for troubleshooting a system using the static pressure method. This course will be offered as a separate class. You do not have to register for the four-day Ventilation Conference in order to sign up for this workshop.
Combustible Dust Workshop:
An optional 3/4-day session devoted to the topic of combustible dust. This course will be offered as a separate class. You do not have to register for the four-day Ventilation Conference in order to sign up for this workshop.
