I have a project that requires me to cool about a cubic foot of air from room temp down to around 40 degrees F. There are several products on the market that might be able to do this based on variations of melting ice or evaporative cooling ("swamp coolers"), but they add a lot of moisture to the air and I need it to be dry. The only things I've been able to think of are portable air conditioners (which are overkill and bigger than I need) and something hacked together from several Peltier coolers. I did a test with one with an airbrush compressor blowing air through a water block attached to the cold side and and a CPU cooler attached to the hot side, and it doesn't feel like it would scale. If push comes to shove I'll just go with an air conditioner but thought I'd check here first for any suggestions. Thanks for any tips.
