I don't want to blow directly onto the water surface, so that the water won't evaporate much and causing the house too humid.
This is also my concern..................however, if 1. the room temp. is even higher than that of water and 2. no evaporation, then, the cooling system won't work.
So, I have another idea...........to have a evaporation system in an enclosed space (just above the tank), then.......
1. water evaporate due to fan
2. water cool down
3. evaporated water recondensed in the enclosed space and re- enter the tank water.
............to do this, the fan should be low voltage one due to safety reason.
is that work?
