Grocery stores do not use standalone refrigerators, I’m not sure why I have to keep repeating this fact when every single person has been in a grocery store and seen refrigerated cases that have a dozen or more doors.
They use cold cases and have rooftop or outdoor condensing units and evaporators inside of the cold cases/freezers/etc. There’s refrigerant piping running all over the place and there’s a bunch of sensors and relays that are automated to manage the refrigeration system.
My assumption is the Danfoss control system they’re using is EOL, it’s the grocer’s responsibility to upgrade their automation equipment if it’s unsupported.
