Refrigeration nameplate tonnage capacity vs actual KW drawn
I'm perplexed trying to understand the ton rating capacity vs the actual KW drawn by the chiller at our facility. The chiller unit is a Trane Model: CVHF 570. I believe this means the nominal capacity is 570 tons. This converts to ~ 2004 KW. Yet it typically draws around 230 amps when loaded up substantially. Since it is a 575 volt unit, the actual KW drawn are approximately 230 KW, which is nowhere near the nominal capacity of the chiller. I would love if someone could solve this discrepancy for me.
