What is the typical range for leaving water in an efficiently operating induced draft cooling tower?

The typical range for leaving water in an efficiently operating induced draft cooling tower is between dry-bulb and wet-bulb temperatures. This range is significant because it reflects the cooling tower's ability to transfer heat from the water to the surrounding air effectively.

In an induced draft cooling tower, water is cooled by evaporation, where a small amount of water evaporates into the air. The wet-bulb temperature represents the lowest temperature that can be achieved through evaporation, while the dry-bulb temperature denotes the actual ambient temperature. When the leaving water temperature is situated between these two temperatures, it indicates that the cooling tower is functioning properly and efficiently utilizing the heat exchange process and evaporation to lower the temperature of the water adequately.

This relationship is fundamental for HVAC and cooling system design, as it helps ensure that the cooling tower operates within optimal conditions, thus maximizing energy efficiency and performance.
