So I am trying to do a diy air conditioner for my room that uses much less electricity than the average air conditioner. My design is simple. Have a cooler filled with ice water and tubes inside of it and then a small water pump to pump water through the tubes. The tubes will be circulating outside of the case where a fan will be blowing through them and since the tubes will be cold (due to the ice water inside) it will theoretically cool my room. the only problem is condensation. Not only do I not want to deteriorate my build by increasing the amount of water being blown into the room, but I also really don't like humidity. I've noticed that no matter how humid it gets, my liquid cooler from coolermaster never seems to have any condensation whatsoever. How is it that liquid coolers are able to function without condensation and how could I use that principle to keep my air conditioner from condensating?
 
All of the liquid is contained using seals. There is no room for air or water to come or go, so there is no way for the water to go out of it.

The main reason there is no condensation is because a liquid cooler can only cool to room temperature. Condensation only attracts to things cooler than the surrounding environment. For example, a toilet bowl in a warm room will begin to sweat because the water inside of it is much colder than the temperature around it.

The reason your AC system condensates is because the water inside of it is colder than the surrounding environment.
