These chillers will be serving a 200 apartment hotel. The piping system is 4-pipe so I think they'll want to run it year round just in case someone is hot in their room but I'm not exactly sure if that's common or not. This is in Utah so it can get down to the negative temperatures now and then. All time lows can be -20 F although very uncommon. However, going 50% glycol seems kind of like a waste. Any insight on this is appreciated.
