A chiller AC is an air conditioning system that uses a compressor to cool air. It is typically used in commercial buildings, as it is more efficient than a standard air conditioner. The compressor works by compressing the refrigerant gas, which causes it to become colder. This cold gas is then circulated through the building, cooling the air inside. The compressor also removes humidity from the air, making it more comfortable. Chiller ACs are more efficient than traditional air conditioners because they are able to cool larger areas with less energy. They are also quieter and more reliable than traditional air conditioners. Chiller ACs are a great way to keep your building cool and comfortable during the hot summer months.
