I've always wondered about the efficiency of water cooled vs 'normal' AC units. So, I did a search, and apparently water cooled used to be more efficient (assuming plenty of water available), but not so much any more. https://www.araner.com/blog/water-cooled-systems-and-air-cooled-systems has a comparison (they make both systems) However, https://www.energyresourcesgroupinc.com/erg-bulletin/air-vs-water-cooled-equipment/ says that water cooled can be 2x (or more) efficient than air-cooled. And then there's this https://noraideas.com/air-source-heat-pump-vs-water-source-heat-pump/ which looks like slightly different technology than water tower-based. So, now I know - it depends ;-) --------------------------------------------------- PLUG-discuss mailing list: [email protected] To subscribe, unsubscribe, or to change your mail settings: https://lists.phxlinux.org/mailman/listinfo/plug-discuss
