Why aren’t chilled ceiling tiles/panels used to cool rooms in North America?
In the Henry Gifford interview, he said “You should add or remove heat by moving water or refrigerant only, not by moving air around.” This reminded me of articles I had read about European HVAC systems that use chilled ceiling panels to cool rooms and have separate dehumidification systems. This sounds like a very efficient approach – especially in hot humid environments. Why don’t you hear more about this sort of system in the US?
