The fluid responsible for this heat exchange is the air at ambient temperature at the base of the tower. Once condensed, the steam is pumped back towards the receiver so that it can be re-used as a heat-transfer fluid. The cooling air travels up through the tower and exits through the highest part thereof.The plant can be used to reduce not only its own electricity consumption, but also water consumption.
