Free Webinar: Optimizing Ducted Heat Pumps for Residential Electrification - Efficiency Comfort and Low Loss Duct Systems, March 12, 9 - 12 pm PT
Event Description
This three-hour class will deal with Low-loss Duct Systems. The relevant Performance Factors are: duct leakage, duct conduction, room-by-room airflow, and system airflow. Instructor Dan Prerunko will review design, installation and commissioning details as they relate to duct system performance for each of these performance factors. These performance factors can be applied to both conditioning and ventilation system ducts. Dan has designed, built and commissioned both retrofit and new construction projects that exemplify the concepts covered in class. Course content will include design examples, photos, installations, and test results from commissioning.
Learning Objectives -
The objective of this course is that at the conclusion, participants will be able to:
