Larger systems can use cooling towers which leverage evaporative cooling. Also, arid climates can use swamp coolers to cool a space. They work on the same principal. When water evaporates, it pulls energy from the surrounding medium, causing the temperature to drop.
- maxerickson 10y agoThis article has a nice diagram and some explanation: http://www.buildings.com/article-details/articleid/5757/title/what-a-water-cooled-hvac-system-can-do-for-your-building.aspx http://www.buildings.com/article-details/articleid/5757/titl... In the discussed example, the water cooled system uses ~1/2 the energy of the air cooled system.
- abakker 10y agoIn CA, swamp coolers can be really great - http://www.homedepot.com/b/Heating-Venting-Cooling-Air-Conditioners-Coolers-Evaporative-Coolers/N-5yc1vZc4lr http://www.homedepot.com/b/Heating-Venting-Cooling-Air-Condi... I used one when I worked with a friend in LA on a car restoration project. They can generate a LOT of cooling very quickly as long as it is dry outside.
