I don't know how to describe it, but I understand what you all mean by "air-conditioner."
Actually, there's this one spot in the Polynesian where my family really gets a good, rich whiff of that "Poly Smell." It's when you're headed out the back door of the GCH on the bottom floor right beneath to monorail station. And those automatic doors go "WHOOOSHH!" open and this flood of Disney scent just bombards your nose. I don't know what makes that smell, but sometimes I'll be walking around the neighborhood or going into someone's house, and I just kinda go, "Whoa! There it is!"
(Of course, everyone looks at me like I've grown a third eye when I do that, but then I remind myself that it's because they're unenlightened non-Disney people, which always makes me feel better)
And, just wondering if this happens to anyone else. When I come home from Disney, and I open my bag to unpack, some of the Disney air gets trapped inside and there's this moment where I feel like I bottled pixie dust and brought it home with me.
Sorry, I know that sounded weird. But I know half of you are reading this and laughing out loud at your computer screen going, "OMG! That TOTALLY happens!"
