Engineers map outdoor weather data onto the chart to determine the required heating, cooling, or humidification loads to bring indoor spaces into the ASHRAE comfort zone (typically between 20∘C20 raised to the composed with power C 25∘C25 raised to the composed with power C RHcap R cap H Preventing Mold and Condensation

The psychrometric chart is a graphical representation of the thermodynamic properties of moist air. It is an essential tool for HVAC engineers, meteorologists, and building scientists to visualize and calculate air conditioning, drying, and humidification processes. psychometric chart

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
