Why Does the Cfm Per Ton of Air Conditioning Vary?

The cubic foot per minute, or cfm, per ton of air conditioning varies depending on application. Approximately 400 cfm is required for normal use, while 500 cfm is needed for high sensible heat situations. High latent heat loads use 350 cfm. Sensible heat directly affects the temperature of the room, while latent heat does not affect temperature because it causes a change in state.
