I never understood why some like 18 degrees celsius. It would only make sense if they kept their house at a lower temperature than that in the winter.
pretty cold, most of the kids have light jackets on
i blast the classroom at 18. on turbo. at home i have one of the big stand up units. I set it to 24 and put it on eco mode. that was it turns on only when it gets up to 26, cools it down to 23, then turns off the ac and only runs the fan til it gets back up to 26. i hate the bill, but i hate the humid hot summer more. generally ill run the dehumidifier for an hour before i get home.
Koreans do seem to be willing to use air con much more than in the past very very recently. I guess one of the positive changes here.
1. Is "air con" actually often said in some native English-speaking countries? I have never heard it in 30 years in Canada nor in my travels across America, US network TV upbringing nor American films.
I actually have no idea either. When I left NZ, I only knew one person with an air con. That was my brother-in-law, and he bought it back from Australia in the mid 1980s. He just called it an air conditioner when I asked him what it was. I learned the term air con from living in Korea.
