Practically speaking, no. The amount of heat in water and the speed at which you need cold water to flow thru a line would necessitate a compressor. Remember the line will even have heat in it that must be removed. Even with a loop to a cold water storage box it would take time for a compressor, of course depending on the amount of water and the temperature needed. Small chillers are available in different capacities and in small sizes like cold water drinking fountains.

For peltier cooling buy one of those ice chests that run on ac/dc or just use your refrigerator or ice.
