Hvac Ductwork Basics Trunk Duct Fittings Elbows Namesођ 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. Hvac fittings play a crucial role in connecting various sections of ductwork. these components ensure an airtight seal between duct segments, preventing air leaks that can reduce system efficiency. they come in different shapes like elbows, couplings, and tees, each designed for specific layout needs. A reducer is usually placed in the supply trunk after 3 or 4 branches have been tied in. this helps to equalize the duct pressures and balance the airflow. as you can see, example 1 is quite sharp on the reducing side. this can be minimized by making the reducer longer. reducers are not the enemy. quite the contrary.

A vent cap fitting helps the performance by protecting the open end of a ductwork vent stack. includes ells, tees, and reducers, are responsible for equalizing the duct pressure and balancing the airflow. for example, a reducer is a fitting that’s used when a change from one size duct to another size is needed. see duct fittings. 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:.
