HVAC System Duct Sizing, Air Flow, & Indoor Air Quality Workshop

This two-day workshop is focused on the heating and cooling systems in residential and commercial applications. The proper sizing and installation of ductwork in buildings is governed by the type of HVAC system employed, construction details of the building, individual room loads, entire building load, the size of the HVAC equipment, and the pressure drop in the duct system created by friction and components within the duct system.

Attendees in this workshop will perform load estimating procedures in order to determine proper ductwork sizing and design, and use a duct calculator. With a complete understanding of the fundamentals of load estimating and duct sizing, new equipment can be properly sized and installed, and existing equipment that is not performing efficiently can be evaluated, allowing for necessary air flow adjustments, air balancing, and duct modifications and repairs. The topics of temperature rise in forced air heating systems and proper air flow relative to the safe and efficient operation of these systems is also covered in this workshop.
