Frequently Asked Questions
What is the difference between sensible and latent load?
Sensible load refers to the heat gain or loss that affects the air temperature, while latent load refers to the moisture gain or loss that affects humidity.
For more information, see the HVAC Design Guidelines from the U.S. Department of Energy.
