Our proposed two distinguished lecturers and our afternoon course have been submitted to our Regional Vice-Chair. Please mark your calenders for:
Wed Nov 21st – Greg Scirivener, as he presents at our lunch meeting and we are also offering an afternoon course on “Heat Pumps and CO2 as a refrigerant” at the U of A Faculty Club.
Greg Scrivener started in the refrigeration industry as an apprentice refrigeration mechanic in 1997 and completed his journeyperson certification in 2003 with an award for “Most outstanding new Journeyperson”. Continuing to work in the refrigeration industry, Greg completed a B.Sc. in Mechanical Engineering with distinction from the University of Saskatchewan in 2011.
The use of CO2 as a refrigerant has grown in the residential, commercial and industrial refrigeration and heat pumping industries. This presentation will explore the different applications that have used CO2 and will examine its efficiency as a refrigerant in different conditions. While reviewing subcritical and transcritical operation of a CO2 refrigeration cycle we will dispel myths about the efficiency of CO2 and understand which applications are best suited for its use as a refrigerant. The presentation will also explain the peculiar operation of systems operating with refrigerant above the critical point including the unique ability to increase compression ratio and efficiency at the same time.
Wed April 17th 2019 – Heather Platt, P.E., MBA from North Carolina as she presents at our dinner meeting on “Design vs. Facilities Maintenance” at the U of A Faculty Club.
Heather Platt has spent the past 25 years helping buildings operate (and perform) better, improving energy efficiency, and enhancing ease of use for the facility staff. She has spent the majority of her career in the healthcare sector
Design firms are being pushed by clients to save time and money, but in doing so we run the risk of providing the code minimum design or not spending the right amount of time investigating current conditions. This leaves projects that end up costing a lot more time and money for both the engineer and owner. The presentation digs into some of these issues based on actual project results.
