Location: Winooski

Join Chris Morin to apply the principles of ACCA Manual D, Residential Duct Design, to ducted mini-splits and whole home heat pumps. This session will start with a review of the universal rules of duct design. With a focus on low load applications with mid-static indoor units, Chris will go on to discuss

• Determining available blower static

• Calculating total equivalent duct length and the impact of duct sizing

• Accurately calculating friction loss

• Example with low-, mid- and high static air handlers

• Duct diagnostics: air velocity, static pressure, air flow…

Learning objectives

• Find relevant information for duct sizing in equipment specifications

• Apply equipment specifications to calculation of available static pressure

• Distinguish system attributes that contribute to friction losses

• Evaluate duct performance through performance testing
