Cooling towers rely on evaporative cooling. The ambient wet-bulb temperature dictates the absolute lowest temperature to which a cooling tower can cool process water. ✅ Summary of Psychometric Principles Are you designing for a (hot/humid vs

The psychometric chart acts as a visual calculator for moist air thermodynamics. By plotting two known air properties, you instantly unlock the complete state of the air-water vapor mixture, enabling precise HVAC engineering, load calculation, and process design.
