Session 1: The Basics of Air | 3.5 Hours Mechanical systems distribute air for ventilation and some heating and cooling systems also convect air. At the heart and soul of forced air systems and modern ventilation systems is the ducting and builders have often not paid enough attention to how ducting should be designed and installed. Worse still, many workers and sub-trades take drastic steps when trying to complete ducting installations into structures that have not been designed or constructed to provide effective and efficient ducting layout. It is no longer acceptable to just notch, cut, and nibble through the complex structure and building envelope, and it is also no longer acceptable to simply hope that air circulation will result in comfortable and safe living environments. This session looks specifically about the affects of duct size, run lengths, duct shape, duct sealing, field modification of ducting to work around the rest of the building. No conversation about the HVAC system can be beneficial until the basics of air are understood.
