How to design your duct system. designing your duct system involves several steps such as sizing your hvac unit, choosing your duct material and size, calculating your airflow requirements, laying out your duct system, and building a material list. here are the steps to follow:.
Hvac Duct Sizing Guide Image To U So, if you like to learn the basic design skills including this duct design, consider enrolling in the course. it’ll give you a head start. 1. calculate the cfm for each room. most hvac units are designed to have a 400 cfm of airflow for every 12000 btu or 1 ton of cooling capacity and 12000 btu divided by 400 cfm is 30. Ubstitute in the equations above. let’s use 16 inches for the minor axis, then the equivalent rectangular duct dimension will be 16”x 51”, and flat oval ducts with a 16 in. nor axis will be 16” x 53”. what this means is that all three ducts, 30” round, 16” x 51” rectangular, and 16” x 53” flat oval will have the s. A good hvac duct sizing rule of thumb is to measure rooms in your home, the necessary airflow rates, and friction loss rate. using these numbers you can calculate the appropriate hvac duct size. for example, a one to ac system typically uses 10 inch ducts, while a 4 ton ac system requires 18 inch ducts. there are several variables to consider. We have included charts for most of the popular standard air duct sizes. these include: round flex duct: 5 inch – 20 inch. metal round pipe: 5 inch – 20 inch. 4 inch rectangular duct: 6 inch – 24 inch diameter. 6 inch rectangular duct: 4 inch – 30 inch diameter. 8 inch rectangular duct: 4 inch – 36 inch diameter.
