Why is 400 cfm a ton

Answered By: Cyrus Clark Date: created: Sep 25 2021

400 CFM per ton of air conditioning: The higher CFM is required to remove the sensible heat from the environment. However, if you have an environment that has high humidity then 350 CFM per ton is better. At the lower CFM the coil is colder and the air spends more time on the coil and increases dehumidification.
