We just dissembled and stored away our bedroom window air conditioning unit, a bit of a pain in the behind, but necessary as autumn weather starts letting itself be known in our area. Wouldn't it be nicer if your air conditioner wasn't an ugly and loud appliance and instead was integrated into the shape of window blinds? Oh, and it would also be solar powered, so no need for power cords!
Designers Nari Kim and Pullip Lim envision their air conditioner to operate even while the windows are open:
By installing Briz on the windows, which is operated by solar power, fresh air can be supplied as water runs through both tubes beneath the bottom part of the blinds emitting dry mist (fine water particles). The evaporation heat caused by the dry mist cools the hot water that enters the window. This, instead of artificial cold wind, natural fresh air that like the breeze of the forest can be supplied by using this system...[without] worry about the expensive electricity bills because it operates only on solar energy.
Sounds a bit like a miniature swamp cooler, but in a smarter, space and energy efficient form. More about this air conditioning concept at Yanko Design.
