A chiller AC unit is a type of air conditioning system that uses a compressor to cool down air. It works by compressing a refrigerant gas, which is then used to absorb heat from the air. The heat is then released outside, cooling the air inside the building. The compressor is powered by electricity, and the chiller AC unit can be used to cool down large areas, such as commercial buildings, warehouses, and industrial plants. The chiller AC unit is a great way to keep a building cool and comfortable during hot summer months. It is also energy efficient, making it a great choice for businesses that want to save money on their energy bills.
