Seminar 21 -- Designing for Air Source Heat Pumps in Cold Climates

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

This presentation deals with lessons learned from a recent Ontario healthcare project, which introduced hydronic Air Source Heat Pumps (ASHPs) to help transform an existing office building into a minor procedures centre. When considering overall seasonal efficiency, ASHPs present a much stronger case than traditional electric systems. However, they cannot perform reliably on a design day. Pulling from operation data from of a full calendar year, we will explore the possibilities and challenges associated with this implementation, as well as other uncommon new strategies that support energy efficiency.
