period three
Sensible Heat Ratio
This period is devoted to understanding the term sensible heat ratio and how
it is represented on the psychrometric chart. The ratio of sensible heat gain to
total heat gain is one of the most important factors affecting air conditioning
system requirements.
If only sensible heat is removed from the air, the line representing this change
moves from the original condition horizontally to the left. This results in a lower
dry-bulb temperature, while the moisture content (the humidity ratio) remains
constant.
