What size supply duct for 3 ton unit.

Take this number and multiply by 1,000. Then divide the answer by 12,000. The answer you get is the tonnage or size of your system. Let's say there's a 24 in the model number. Then the tonnage is (24,000/12,000) or 2 tons. If you're putting in a central air conditioning unit you'll be incurring quite an extensive cost.30 Oct 2023 ... Are you considering upgrading to a variable speed heat pump, but you're unsure if your existing duct system can handle it?2,200 CFM. 6 Ton Unit. 2,400 CFM. This chart is quite simple to read. Example: A 5-ton unit requires 2,000 CFM airflow. A 3-ton unit requires 1,200 CFM airflow. Now, it is important to understand when the 400 CFM per ton rule of thumb should not be applied. We will look at when the CFMs per BTU of cooling should be higher and lower:So if you go 25% bigger, I'd expect to notice much improvement in capacity & efficiency you'd certainly need more duct and register capacity. I'd bet staying 2 ton and having the duct system checked and improved would be all you need. Reply. 08-02-2013, 08:27 PM #7. kangaroogod.Trunk/supply duct sizes 3 ton to 2 ton. When I moved it, I had a 3 ton system with only 5 supply ducts (6" flex). The static pressure caused a windstorm in each room. I had two more supply ducts added, and the rest of them increased to a larger size (probably 9" or 10" flex) to lower the static pressure.

Shorten the ducts by not putting supplies at the perimeter. This one goes with step 9. You don't need to put the ducts at the perimeter in new homes because we have much better windows. You can shorten the overall duct length and total effective length by not running the supply ducts out to the perimeter.

3. If necessary, modify the existing duct and/or install new duct that has been sized at a friction rate that will accommodate higher Cfm values at OEM specified static pressures and industry standard velocities. (Use ACCA Manual D to size your duct-work or use a duct calculator and select .07 friction rate value instead of the typical .10). 4.

However the main supply is only 18”x12” and runs 50 feet, it branches off to four 8x8 supplies on the 2nd floor, five 8x8 supplies on the first. By my calculations an 18”x12” main supply will only provide 430CFM or enough for a 1-ton system. So it looks like I would need 1400-1600CFM or something closer to 26”x26” or 28”x28”.

Cat #: 12X70 Model/Part #: ...By using this equation, we can determine the size of the return grille we need for 400 CFM airflow like this: Grille Area (400 CFM) = 400 CFM ÷ 500 FPM ÷ 0.7 × 144 = 164 Sq In. That means we will need a grill with at least 164 square inches of area to accommodate for a 400 CFM airflow. 10×10 grille, for example, has a 100 sq in area; it ...Recommended airflow is typically 400 cfm per ton of AC. A 3 ton AC would therefore need 1200 cfm airflow. With only 423 sq in of return your air velocity through the grille would be just over 400 ft/min, a good number as far as noise is concerned. Air velocity of more than 500 ft/min will be too noisy for a residential system.
