I am working on laying out a system for meat cutting plant. Everything is mostly old crap that is falling apart. The aging room cooler and drip cooler room have evaps pulled out of rail cars.
I am looking at putting in a 40 HP chiller for their aging room, drip cooler, and cutting rooms. They want to add a couple of cooler rooms. They are all to be held @ 36 F.
They also want to add a couple of freezers that they are going to keep @ -10F. I would like to use water cooled conednsers and run the glycol loop for the condenser.
The condenser water will be 25 F or so. I am concerned about the water regulating valve hunting with such cold water. Even if I sqaure that away will such a low flow/ high delta cause some kind of problems? Still working on the size but will probably be a 5HP or 10 HP. If it is a 5HP is will be a hermetic with a COAX and the 10HP will be a Discus with an S&T.
Any input would be appreciated.
