Design Class Sessions (Phase I, Phase II, and Nonstandard Air Design)
The Conference Design Classes include more than 20 hours of classroom experience in which the registrant will have the opportunity to work out actual design problems. At least two staff members will lead each classroom design section of about 20 registrants.
Each registrant will receive classroom materials that include a copy of the ACGIH publication, "Industrial Ventilation: A Manual of Recommended Practice for Design," various other technical publications, and plans and specifications for specific ventilation systems to be designed. Registrants must bring a scientific calculator capable of performing square root and exponent functions for use during classroom sessions. Participants of the Phase II class are advised to bring a computer as a computer-aided tool will be provided and used in the class.
Registrants should pick the class session that best fits their ability, past experience, and their goals in ventilation design. To help make a selection, click here to take the Self-Placement Questionnaire and indicate your selection on the Registration Form.
Operations & Maintenance Class Session
This class uses a sample industrial ventilation system to permit the hands-on application of basic ventilation system design, operation, and maintenance principles. The class consists of a combination of seminars, classroom lectures, and hands-on application sessions.
Each registrant will receive classroom materials that include a copy of the ACGIH publication, "Industrial Ventilation: A Manual of Recommended Practice for Operation and Maintenance," various other technical publications and handouts. Registrants must bring a scientific calculator capable of performing square root and exponent functions for use during classroom sessions.
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.
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.
