13 2 ductwork air leakage 13 3 duct leakage tests. Most heating cooling systems now are dual units with different elements for heating or cooling but sharing a blower and ductwork to distribute. This manual provides the hvac system designer detailed information on duct design and u s. The purpose of residential ductwork design is to properly distribute the airflow produced by your heating cooling system to your house.

This involves return air unconditioned coming into the heating cooling system. I ll follow that up with articles on the process we use in designing duct systems including available static pressure equivalent length and choosing fittings. The model applies to system up to 60 feet from unit to register. Today i ll start with what you do in the hvac design process before you get to the duct design phase manual d as well as the physics of air flow when it s constrained by ducts.

In addition to the basic engineering guidelines for the sizing of hvac ductwork systems the. We ll include a full worked example as well as using cfd simulations to optimise the performance and efficiency using simscale. Refer to the links on the left for more information. Below is a simple model for determining duct sizes.

If you would like a little more detail upgrade to our premium manual d service and get a 3d render image of your duct design in addition to the official basic manual d. To maintain balanced air pressure and air movement your duct system needs return vents for air in the room to be pulled back into the hvac system. How to design a duct for an hvac application. 6 tips for good ductwork design.

Our hvac duct sizing and duct design service is now offered in 3 different versions our basic manual d is the conventional hvac manual d with a basic 2d drawing. Because of the complexity of designing duct systems we highly recommend using the acca manual d for sizing ductwork or consulting a professional hvac contractor. In this article we ll be learning how to size and design a ductwork system for efficiency.
