This two-day introduction to the design and evaluation of laboratory HVAC systems combines lecture, class discussion, hands-on laboratory work, and group activities. Topics include: basic airflow principles; ventilation equipment exhaust requirements; OSHA, ANSI, ASHRAE and NFPA regulations; fume hood testing and laboratory controls. Real life laboratory design and construction projects are used as examples throughout this HVAC design course. All course concepts come together in an activity in which participants learn the critical questions to ask when reviewing mechanical drawings as part of a laboratory planning project.
