When the outdoor air is cool enough, it can provide 100% of the chilling which is almost “free cooling”. Since we still need a pump to circulate the fluid in the loop and a fan in the air cooled condenser, it is not completely free, but it is at least an 85% reduction in energy consumption during this period.

The condenser water is then falling from the infill onto the basin and goes back to the chiller via gravity flow. Since the condenser water loop breaks at the cooling tower, it is an open loop piping system. Because the cooling tower uses evaporative cooling, it relies on the wet bulb temperature rather than the dry bulb temperature.
