Hi, Everyone, I'm working on a research for centrifugal chillers. I want to make an investigation whether 'subcooling' and 'suction superheat' are standard measurements for different brands of centrifugal chillers(McQuay,Trane,Carrier,York). For McQuay, subcooling and superheat are standard measurements. For, Carrier, they don't measure subcooling and suction superheat. I am not sure whether they are standard for other brands of chillers or not. In addition, can anybody provide rating data(performance data) of different brands of chiller.
