How does a chiller work? -

The air-cooled chiller uses a shell-and-tube evaporator to exchange heat between water and refrigerant. The refrigerant system absorbs the heat load of the water to cool the water to produce cold water, and the heat is brought to the finned condenser through the compressor, and then dissipated to the outside by the cooling fan.
