The Magic of Evaporation
This company from Japan, with a century-long legacy, crafts air conditioners that cool things down by swapping heat. On a different note, the RKF Shizuoka evaporative air cooler taps into the natural magic of ‘evaporation,’ like a cool breeze over a lake, keeping electricity use to a minimum.
