Air conditioning chillers are a type of cooling system used to cool large spaces or industrial processes. They are usually used in commercial and industrial buildings, such as factories, warehouses, and office buildings. Air conditioning chillers work by circulating chilled water or a refrigerant through a closed loop system. The chilled water or refrigerant is then used to cool the air in the space or process. The air conditioning chiller system is composed of several components, including a compressor, condenser, evaporator, and expansion valve. The compressor compresses the refrigerant, which is then passed through the condenser, where it is cooled. The cooled refrigerant is then passed through the evaporator, where it absorbs heat from the air. The heat is then released outside the building. The expansion valve then reduces the pressure of the refrigerant, allowing it to flow back to the compressor and start the cycle again. Air conditioning chillers are a cost-effective way to cool large spaces or industrial processes, and they are becoming increasingly popular in commercial and industrial settings.
