Funny, and not to side track the thread, but I and 1 of our controls techs have been working at a school with a 450ton RTAC that has about 150 tons too much, low load conditions and unocc time I am bangin a compressor on and off in 10 min itervals. And to add fuel to the fire it's a way out in the country type place and they have power consumption issues. So we are trying to make a very efficient grossly oversized chiller live
It's hard to stop a Trane. but I have made one helluva living keeping them going.
