How does a water-cooled air conditioner work?

There are several different ways that water is used in air conditioning. The most common use is in cooling towers . A cooling tower can be any size, from really gigantic down to the size of an automobile. In a cooling tower, air blows over water to create evaporative cooling , and this cooler water is used in the heat exchanger of, say, an air conditioner. A more direct form of evaporative cooling is often found in greenhouses , farmers' markets and chicken houses. In these kinds of systems, water flows over a mesh, and a fan blows air through the wet mesh into the building. Humid, cooler air is the result.
