Seminar 33 -- Future Directions in Sizing Residential and Small Commercial HVAC Equipment ✓ Most Recent

This product is a PDF that contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.

The seminar focuses on the key issues related to the sizing of modern residential and small commercial HVAC equipment. Industry updates of historical HVAC sizing procedures assist manufacturers, designers and installers working with new innovative multi and variable capacity HVAC equipment. This equipment is quickly gaining popularity in the residential and small commercial HVAC market. One presentation provides an overview of the recently updated industry accepted, residential and small commercial HVAC equipment sizing procedures (e.g. ACCA Manual S), which is referenced in energy codes and home performance contracting energy conservation programs. Another presentation focuses on research conducted to justify greater sizing flexibility when sizing heat pumps in heating dominated climates to reduce back-up electric resistance heating, in climates where humidity control has been addressed or is not a critical design issue. A third presentation focuses on “sizing for humidity control” based on dehumidification modeling analysis efforts conducted as part of ASHRAE RP-1449.
