Trane had and issue with some Timken bearings doing this due to the oiler orphis for that bearing not being big enough. It's an oiled bearing. These compressors spin max 3600rpm but depends on design and application. Every chiller is purpose built be it for comfort cooling or a process application. No tach feedback, it's just a WAG from programming motor parameters and motor speed at 60hz. The York machines are fairly complicated and way over engineered for typical comfort cooling applications in my eyes, Yorks market share is Govt/Military and Ship cooling. So everything they build is to those specs. I can't really stand being near them when they are running as they have a rumble/noise that makes me feel like I need to throw up. | |||
