Recap: November Chapter Meeting

For those of you who were unable to make this month’s chapter meeting, you missed a lively discussion of CO2 Refrigeration and Heat Pumps. We had over 45 guests in attendance at the Motif hotel ballroom in downtown Seattle. Our special guest ASHRAE Distinguished Lecturer Greg Scrivener, president of Cold Dynamics, came in from Edmonton, Alberta where it was blizzard conditions. He gave a great presentation covering chemistry, regulations, safety and applications. Who knew Pressure-Enthalphy charts could spark so much conversation?

The presentation is available below.
