I'm wondering something. Is it possible to, by means of a strong fan or maybe a circulating fan, or a whirling fan, to maintain maximum cooling in an air conditioned room. The room isn't very big, say 10' by 12'. Here's the clincher. A large window needs to be opened. All the time. No sense in explaining why.
I read years ago that the atx computer power supply spec mandated that fans pull heat out of the case instead of pulling air in. The reason is so the case would be pressurized, and (presumably) keep dust out. But that seems backwards to me. You pressurize by blowing into the case (or push air around inside it). And possibly having a bigger inlet then outlet? Does any of that make sense? Fluid mechanics is weird I know.
I suppose I could just try something. Obviously a fan blowing at someone (or something) seems to lower it's temperature no matter if there is an ac or not. But to achieve equilibrium, where hot air that would otherwise enter and mix with cool air, would be kept at bay, is what I'd like to achieve.
