Greg Scrivener, President Cold Dynamics ASHRAE Distinguished Lecturer
This presentation is specific to the regulatory requirements of the CSA B52 code in Canada. The presentation will review the code requirements that apply to the location and installation of refrigerant piping in both industrial and commercial applications. Because of the regulatory environment in Canada there are large sections of CSA B52 that do not have significant enforcement, possibly leaving design engineers responsible for compliance. We will review the installation of chiller plants, split systems and VRF (Variable Refrigerant Flow) piping as well as calculations of occupancy based refrigerant concentration limits. Changes have been made to the refrigeration code in the USA that will eventually make their way into Canadian code, will also be reviewed.
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. Having worked in roles from all the way from mechanic to design engineer, Greg can offers a comprehensive view point on refrigeration related construction and design. In 2014, he founded Cold Dynamics and is now involved with refrigeration consulting work including design, inspections, commissioning, advanced troubleshooting, energy auditing, control sequence optimizations, and training. Coupled with a passion for energy efficiency and the environment, Greg’s unique experience leads to an in-depth understanding of the parameters affecting efficient refrigeration system operation
