What is the significance of the dew point temperature on a psychrometric chart?

The dew point temperature is the temperature at which the air becomes saturated with water vapor and dew or frost begins to form. On a psychrometric chart, the dew point temperature is an important parameter, as it indicates the maximum amount of moisture that can be removed from the air. Engineers can use the dew point temperature to determine the required cooling coil temperature and airflow rate to achieve the desired dehumidification effect.
