Layout Hvac Duct Design Example

Duct system design page 1 5 energy is due to elevation above a reference datum and is often negligible in hvac duct design systems.

Layout hvac duct design example. How to design a dust. There is a wealth of information available concerning air volume determination heating and cooling loads fan selection and specification. The ideal ductwork system achieves both goals by providing enough. System design there is very little information specifically about duct system design condensed into a single document.

This type of system incorporates the use of a trunk line or series of rectangular ducts that act as a main supply channel throughout the house. 15 4 determining air flow at grilles. Easy fast to install just clamp together no rivets screws or welding needed. Adaptable to your existing ductwork.

Guide for how to design a ductwork system. 15 5 determining air flow in ducts. 15 1 balancing the 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.

14 2 acoustical analysis of a ductwork system. Consequently the total pressure or total energy of air flowing in a duct system is generally equal to the sum of the static pressure and the velocity pressure. Clamp together ducting. Leak tight laser welded seams instead of lock form or spiral duct which badly leaks and allows debris harbors and snag opportunities.

15 3 air flow measurement instruments. Duct sizing duct calculation duct design energy efficient ductwork design. Local dealer support. Above and below are examples of simple hvac duct systems.

The diagram above illustrates the fact that the air handler may be centrally located preferred or located elsewhere dependent upon the configuration of your home. 15 2 testing methods and equipment. System is designed to move 3. What does exist is difficult to understand.

As an equation this is written. 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. Ductwork testing system performance. Duct sizing for the two examples would certainly be very different.
