Evaporating water consumes a lot of heat. First the energy to get it to 100 degrees, then the latent energy to do the actual evaporation. Then the steam floats away so that is disposal handled. I'd imagine the volumes of heat are too large to the sort of refrigeration cycle you're talking about. It'd just boil the local rivers and lakes, or lead to a very hot block of dirt then stop working. Note that we're talking double-digit percentages of a country's water consumption here.
