Right up to the very last session, there was full attendance at this year’s National Comfort Institute Inc.’s Summit Conference. Here are the highlights.
To understand the operation of combustion air openings, it’s a good idea to review some airflow basics. For airflow to move through a duct, there must be a pressure difference across it created by an external source. Traditional installations depend on natural forces to create this pressure difference.
Traveling, at least to me, offers a lot of lessons about human nature, life, and yes, the HVAC industry. It can be a microcosm of entrepreneurship and business acumen. What? That’s crazy, right? But not really.
Is it possible there are negative effects caused by uninsulated ducts in conditioned spaces we may have overlooked for decades? Let’s look at some problems you might encounter due to this practice and how you can determine the impact on the performance of your systems.
Being accountable for proper airflow delivery causes a tech to examine every portion of an installation differently. Airflow is no longer assumed since test instruments now measure it. Let’s look at some of the most common obstacles to achieving a successful air balance on a residential HVAC system.
The National Comfort Institute’s (NCI) annual Home and HVAC Performance Summit 2017 is in the final stages of preparation, and HVAC contractors from around the country are invited to attend. The event takes place April 2-4, 2017 at the We-Ko-Pah Conference Center and Resort in Scottsdale, Arizona.
Just because our industry talks about proper airflow, it doesn't mean we’re doing much to address it. Airflow must be measured, plain and simple. Duct design and duct tightness won’t assure proper airflow.
Combustion safety can be sacrificed when fuel-fired appliances needing interior air for combustion are not carefully considered. Many appliances depend on a consistent supply of air from inside the building to operate safely. If this fact is ignored, the results can be deadly.
