ACCA technical manuals are taught by the leading industry schools and vocational programs. Many of our manuals are approved as ANSI standards , and many are referenced inside building codes nationwide.

When using system design software, make sure it is approved by ACCA as compliant with our standards. ACCA provides free training spreadsheets, known as Speed-Sheets, for use with some of our technical manuals. ACCA also provides a number of educational opportunities related to our manuals, including an online certificate program in residential design and an online certificate program in light commercial design.

It now features the use of SI units throughout, updated references and the editing of many illustrations. IBACOS used computational fluid dynamics software to explore and develop guidance to better control the airflow effects of factors that may impact pressure losses within junction boxes among various design configurations Beach, R.

These recommendations can help to ensure that a system aligns more closely with the design and the occupants' comfort expectations. Specifically, the recommendations described herein show how to configure a rectangular box with four outlets, a triangular box with three outlets, metal wyes with two outlets, and multiple configurations for more than four outlets. Designers of HVAC systems, contractors who are fabricating junction boxes on site, and anyone using the ACCA Manual D process for sizing duct runs will find this measure guideline invaluable for more accurately minimizing pressure losses when using junction boxes with flexible ducts.

Depending on the home, you might need a different style of register, diffuser, or grill. At last, we come to Manual D. This one is easy to remember since it has to do with Ductwork. After the technician has run load calculations, selected the right equipment, and determined how the air is to be distributed, the next step is to make sure the air ducts are installed properly.

Proper ductwork installation has to do with the location of your air handlers, the difference between your ducts and returns, and how much air must pass through the duct pipes. The type of air ducts are also important for how your air is distributed. For example, you can have cleaner ducts and a lower friction rate with sheet metal ducts as opposed to flex ducts or rigid fiberglass duct board.

In essence, Manual D is trying to balance the delivery of your air with the amount of friction and static pressure in the system. This is important since poor duct design leads to comfort and indoor air quality problems ACCA. Make sure you vet your prospective contractors with this information. Not only will they be impressed, but you will avoid the common HVAC pitfalls that many homeowners walk right into.

Our goal is to inform customers of all their options so they can make the best decision for their home and family.
