59 Cooling Tower A cooling tower is an outdoor piece of equipment that rejects heat from an indoor chiller to the environment. Incoming warm condenser water from the chiller passes through the cooling tower, in which fans and sprays lower the water temperature via evaporative cooling. The cooled condenser water is returned to the chiller to repeat the cycle. Note that a sizable amount of water is evaporated and lost during the process.
