High Performance Air Systems

Impact of Duct Fitting Selection

This program will discuss the fundamentals of pressure losses in ducts and fittings, how fitting selections affect the overall system pressure requirements, and why the most efficient fitting (one with the lowest loss coefficient) does not always need to be selected. To be reviewed is how to calculate the loss of replacements when the fitting does not fit, and how it affects the total pressure drop of the system. We will also address why the most efficient fittings should be used when initially designing with static regain.

Understanding and Reducing Air System Noise

This webinar will cover the basics of in-duct mechanical noise and how to control it. The presentation will walk through a typical acoustic analysis for a commercial HVAC system and discuss how to select the correct products to achieve the required noise levels in a building. The participant will also learn how to locate attenuation products to maximize their performance while considering their impacts on the overall HVAC system.
