Duct Sizing Jlc Online Hvac The size of supply and return registers (grilles), airflow capacity per room, and the size and layout of ductwork should all be determined by using acca manual d (preferably, by using current computer software approved by the acca). approximate sizing can be determined using the table below. for more on hvac ductwork, visit the jlc field guide. The upshot of all this is that when you're sizing ducts, you have to consider the space those ducts are in. that's where mike macfarland's way cool duct sizing tool (a chart) comes in, and allison provides a link to download the tool. the chart allows you to find the duct diameter that gives you the right velocity and air flow rate (cfm.
Right Sizing Hvac Ducts Jlc Online Ductwork. jlc field guide: ductwork. leaky ducts waste energy and can create room to room pressure imbalances that cause comfort problems, higher energy costs and even moisture problems within the building assembly. Re: hvac ducting that's right adequate duct capacity is very important. a 6x6 round duct has about 28 inches of cross sectional area (if it isn't compressed), a 6x8 rectangular duct has 48 inches, and a 6x10 rectangular duct has 60 inches (but would still leave room for 2 inches of rigid insulation on 3 sides, probably). Now, multiply 3 x 400 cfm to get 1200. you would need a blower that can move 1200 cfm. pro tip: round up – if you’re more than halfway to the next larger size, round up to it. in our example, if you needed 33,500 btu, or 2.75 tons, round up to 3 tons and multiply by 400 cfm per ton for the same result – 1,200 cfm. To calculate the required equipment size, divide the hvac load for the entire building by 12,000. one ton equals 12,000 btus, so if a house or office needs 24,000 btus, it will take a 2 ton hvac unit. if you get an uneven number, such as 2.33 for a 28,000 btu load capacity, round up to a 2.5 ton unit. to use the duct cfm calculator, you must.

The table on the right (or below if you’re viewing on a phone) shows the return duct size for hvac unit from 1.5 tons to 5 tons. based on 400 cfm per ton, the corresponding airflow is also provided. the next column is the diameter (in inch) for round rigid duct. the last column is the number of round rigid duct you need. To choose the right duct size for your home, you need to consider the capacity of your hvac unit, the number and location of your vents, and the friction loss caused by bends, fittings, and obstructions in your ducts. you can use this online calculator to help you determine the optimal duct size for your system: engineeringtoolbox.
