It's a warm day today and this summer will probably be even hotter than the last one, and the last one was a scorcher. Trouble is, my room is always the hottest in the house, because it's high up and has lots of electronics inside it.
Opening the windows isn't enough to cool it down on really hot days. I have one 60 watt fan, and was wondering, which way of using it cools down the room better:
- Pointing the fan out the window to blow out the hot air, sucking cool air in
- Pointing the fan in from the window to blow in cooler air, pushing the hot air away
Yes, I'm the scientist, but I can't figure this one out. My science knowledge tells me that pointing the fan out should work better, but experience says that pointing the fan in is better. But that could be that it just feels like it because it then blows air onto me. My thermometer can't seem to tell the difference either.
Anyone got a definitive answer?
