Ian Crookston, Sobeys' manager of energy management, presented CO2 transcritical system benchmarking. One of Canada's two national supermarket retailers, Sobeys now has 72 CO2 transcritical systems after installing its first in 2009. Crookston outlined Sobeys' benchmarking journey adopting CO2 transcritical, comparing two systems in their Milton and Stradford store locations - the first using low and high temperature evaporators, the latter three temperature ranges and mechanical sub-cooling.
