Air-cooled chillers are refrigeration systems that use air to dissipate heat from the coolant or refrigerant. Unlike water-cooled chiller, which rely on a water source and cooling towers, air-cooled chiller use fans to blow air over condenser coils, transferring heat from the refrigerant to the ambient air. They are typically used in smaller to medium-sized applications, such as commercial buildings and industrial processes, where water availability or cost is a concern. These chillers are valued for their relatively simple installation, lower maintenance requirements, and suitability for environments where water conservation is important.
