A chiller is a device used to cool liquids, often water, for various applications. It works by removing heat from the liquid and transferring it to the environment, typically using a refrigeration cycle. Chill water is commonly used in air conditioning systems, industrial processes, and food preservation. Chillers come in different types, including air-cooled and water-cooled models. Air-cooled chillers use air to dissipate heat, while water-cooled chillers rely on water for cooling. These systems are essential in maintaining optimal temperatures in commercial buildings, manufacturing facilities, and even in large-scale refrigeration setups.
