Water isn't very expensive here but still if figures are correct i won't be able to cool down anything without insaine amount of water. And water isn't even nearly as cold.
What about my second question ? Since fans do a poor job at cooling my apartment at night due to a low amount of heat air can store, would creating a water cycle between apartment and outside help ? My window shelf is basicly 50 x 50cm of metal that seems to have good heat transfer properties. If i used some copper tube and sit it on this outside shelf at night, and make water circulate through it with water pump, and bring cold water inside, would that make a difference ? I am just thinking out loud here, wouldnt be wasting any water here since this would be a closed circle.
