Abstract
A dual evaporative pre-cooling system is installed packaged air conditioning units. The dual evaporative pre-cooling system includes an evaporative media disposed in a housing through which incoming condenser air flows. A water distribution device is disposed above the evaporative media. A sump and a pump are located below the evaporative media to recirculate water through the water distribution device and a ventilation air pre-cooling coil. A plurality of pipes connect, and allow circulation of, a water source discharged from the pump through the ventilation air pre-cooling coil, and to the water distribution device.
