Layout Hvac Duct Design Example

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.

Layout hvac duct design example. Guide for how to design a ductwork system. 15 5 determining air flow in ducts. 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. Duct sizing for the two examples would certainly be very different.

14 2 acoustical analysis of a ductwork system. 15 3 air flow measurement instruments. System design there is very little information specifically about duct system design condensed into a single document. What does exist is difficult to understand.

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. 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. The most common design trunk line layout is provided in the illustration below. As an equation this is written.

15 1 balancing the system. Duct sizing duct calculation duct design energy efficient ductwork design. System is designed to move 3. Adaptable to your existing ductwork.

15 2 testing methods and equipment. Ductwork testing system performance. Local dealer support. The ideal ductwork system achieves both goals by providing enough.

15 4 determining air flow at grilles. Leak tight laser welded seams instead of lock form or spiral duct which badly leaks and allows debris harbors and snag opportunities. Above and below are examples of simple hvac duct systems. Duct system design page 1 5 energy is due to elevation above a reference datum and is often negligible in hvac duct design systems.

There is a wealth of information available concerning air volume determination heating and cooling loads fan selection and specification. 15 6 provisions during design for testing adjusting and balancing. How to design a dust. 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.
