I need a way to generate cool air outside when temperatures are 90s and above. Basically what I am thinking of doing is essentially like positioning a fan right beside a bowl of ice cubes. Only in my case, instead of using ice cubes, an electrically powered cooling device that can slightly reduce the temperature in the area immediately around it, and a fan would blow that cooler air at a person or object I need to keep cool. And, I would like to keep the air relatively dry (50% or less humidity). I don't know a lot about what's out there, but I did read on another forum about using a heat exchanger to generate cool air. I only need to reduce the temperature by 5° to 10° a foot or less away from the cooler.
