WebChilled water systems circulate cold water of between 40º F to 45º F through the air to water air handlers. As the air is cooled and passed through the finned coil, it gives up heat to the water. Most chilled water systems are designed so that, at the maximum air-conditioning load, the water leaving the coil has been heated 10º F. Webreduce chiller efficiency by 10% to 35% and a dirty coil condenser of an air cooled chiller as much as 5% to 15% Chemical cleaning of the inside of the condenser and evaporator heat transfer surfaces can result in a 5% to 10% energy savings – kw/ton Air-cooled chillers are less efficient than water-cooled chillers but cost less as well.
