Study Notes
Psychrometric Chart
- A Psychrometric chart graphs the relationship between the temperature, humidity, and energy content of air.
Temperature Components
- Dry bulb temperature (DBT) represents the temperature as registered by an ordinary thermometer.
- Wet bulb temperature (WBT) represents the lowest temperature that can be reached by a thermometer wrapped in a wet cloth and placed in an air stream.
- Dew point temperature (DP) represents the temperature at which the air becomes saturated with water vapor and dew or frost begins to form.
Humidity and Energy Components
- Humidity ratio, also known as the moisture content, represents the amount of moisture in the air.
