SUMMARY:Residential Duct Air Flow Measurement: Assessing the impact of air flow on ASHP sizing
DESCRIPTION:Duct capacity is often a limiting factor in sizing retrofit heat pumps\, and contractors often size heat pumps based on the existing air conditioner\, resulting in under-sized equipment. A simple 15-minute test can provide definitive air flow capacity of a duct system\, contributing to a proper sized heat pump and avoiding poor system performance—such as noise problems due to restrictive ductwork. Energy Advisors (EA) can easily add this procedure to the scope of an Energy Evaluation. \nThis training will instruct EAs on how to evaluate the airflow capacity of duct systems in homes where the distribution system is not being changed and the primary retrofit measure is the replacement of heating and cooling equipment. In conjunction with other considerations—such as the CSA F280-12 Heat Loss/Heat Gain value—this is a preliminary assessment to provide the homeowner and their HVAC Contractor with data that will help the contractor select the largest ASHP based on existing ductwork. Please note: This course does not enable EAs and other HOT2000 modelers to select specific heat pumps or make direct sizing recommendations. The Contractor is ultimately responsible for equipment selection. \nInstructor and CACEA member Mark Rosen MEA\, Director\, Building Science\, Building Knowledge Canada and a well-known professional architect\, trainer\, and consultant who is passionate about buildings that perform exceptionally well.
