Reply to comment by Klai8 in ELI5 Why are airport ceiling so high? by TrShry

You can have a localized HVAC system that uses chilled water…?

You are correct with your idea of more air = more consistent air temperature / smaller temperature swings….but your explanation is a little off

There are other reasons beyond HVAC such as sound, lighting, room for large signage, and just overall aesthetics.

Pretty sure that many hotel rooms work this way. If there isn't an A/C unit shoved through the wall then there's probably a chilled-water AHU in the ceiling above the door or bathroom.

Yes that was my point. The original comment I replied to stated that you couldn’t use chilled water to locally control a gate’s temperature. But you can

I think there point there was that approach would be more expensive over the lifetime of the airport than building higher ceilings on the first place
