HEAT 1 - Residential Duct Design

Thursday, March 04, 2010  ·  10:30 AM - 12:00 PM

A properly designed and installed duct system quietly delivers the correct volume of air to an intended space and makes all the rooms comfortable. There are three things it should not do: leak more than a skosh, create pressure imbalances, or operate at a static pressure outside of the HVAC system manufacturer's recommendations. Most of this session will be spent showing how to correctly determine friction rate. The techniques used to calculate friction rate are rather basic, but putting them all together is rarely done right. We'll show you how easy it can be to use that duct slide rule properly. There is no way you can absorb all of what ACCA's Manual D has to offer in this short time frame, but we can hit the highlights.

 

By attending this session, participants will

 

1. Find out how to identify flaws that impact comfort, energy efficiency, health, and durability
2. Discover how to use diagnostic testing to troubleshoot duct issues and verify performance
3. Gain practical ideas on techniques and solutions that can be applied in your work
