Psychrometrics (Preview Only)
According to the laws of physics, there is a direct physical relationship between the temperature of an air mass and the amount of water vapor that air can hold. As air cools, it can hold less moisture and as it warms, it can hold more. In this lesson, you will take a look at the "psychrometric chart" - a graphic diagram that allows us to understand the precise mathematical relationships among moisture in the air, room temperature, surface temperature, condensation and evaporation.
At the conclusion of this lesson, you will be able to:
- Recognize and read the psychrometric chart
- Understand how air temperature and relative humidity are related
- Describe the relationship between surface temperature and evaporation
- Understand the significance of relative humidity and surface temperature for mold and mildew growth
