A "Chiller" is a machine used to cool liquids, often in industrial settings. It works by removing heat from a liquid, which is then circulated through a system to maintain a desired temperature. This process is essential in various applications, such as air conditioning, refrigeration, and even in manufacturing processes where temperature control is crucial. In many cases, chillers are used in conjunction with other equipment, like cooling towers or heat exchangers, to enhance efficiency. They can be found in places like hospitals, data centers, and food processing plants, ensuring that environments remain safe and operational by keeping temperatures in check.
