How Many Cfm per Ton of Cooling Does My HVAC System Need?
WebMar 28, 2024 · In a humid climate, that’s somewhere around 400 cfm/ton, plus or minus. That gives you better dehumidification from the air conditioner. In a dry climate, you might push that number up to 500 cfm/ton or even higher because it wastes energy to condense water vapor on the coil. WebMar 28, 2024 · The original question was about how we take heating and cooling loads in BTU/hr and determine how much air flow we need in cfm. We’ve got a term in the equation now for volume and cfm is just volume over time. One of the great things about algebra is that we can divide (or multiply) both sides of an equation by the same thing. outwood academy login
