NOTES: A ceil­ing fan can’t make the air in a room cooler like an air con­di­tioner can. But it can make it feel like the air is cooler. Here’s the ba­sic idea: as you sit in your sti­fling liv­ing room, sip­ping an iced cof­fee, try­ing to keep sweat and con­den­sa­tion from smear­ing the pages of your mag­a­zine, your body - which is pretty hot - is of­fload­ing heat to the air around it. That means that in a still room with­out a fan you’ll quickly be­come en­gulfed in a hot cloud and, as that cloud gets closer to the tem­per­a­ture of your body, you can’t pass off as much heat to it. In a room with a fan, the cloud blows away. The new air cir­cu­lated around your body is cooler, which al­lows your body to give more heat to it, which makes you cooler. Pretty clever and it takes a lot less en­ergy than a re­frig­er­ant loop. Es­pe­cially if it’s one of Haiku’s H Se­ries fans, which fea­ture a more re­fined blade design than the slats on your av­er­age ceil­ing fan and in­te­grate sens­ing tech­nol­ogy so they run only when you need them, at the ex­act speed you re­quire.
