The Psychrometric Chart
notes
Effect of Sensible Heat and Moisture Changes
When either the sensible heat content or the moisture content of air changes,
the point on the psychrometric chart that represents the original air condition
moves to a position that represents the new condition of temperature and/or
humidity.
For example, if sensible heat is added to air, the air condition moves
horizontally to the right.
Conversely, if sensible heat is removed from air, the air condition moves
horizontally to the left. As long as the moisture content of the air remains
unchanged, the humidity ratio remains the same. Therefore, this movement
follows the horizontal humidity-ratio lines.
