ARLINGTON, Va. - The Air Conditioning Contractors of America (ACCA) has released another in its series of computer-based training packages known as “HVAC Essentials.” The latest package is entitled “Understanding Manual Q: Low Pressure, Low Velocity Duct Design in the Real World.” Manual Q is ACCA’s industry standard for designing duct systems that are used in the majority of low-rise commercial applications.

Combined with the recently-released “Understanding Manual N,” these two packages provide a complete training system in light commercial sizing and duct system design.

Understanding Manual Q is a set of five CDs; each CD contains appropriate handouts and the training session itself, which lasts about an hour. Taught by presenter Jack Rise, the CDs are self-directed, allowing technicians, contractors, and students to proceed at their own pace, without requiring long periods of time away from work. According to ACCA, the material is presented in plain English, with lots of real-world examples that make the principles easy to learn and apply.

The five CDs in Understanding Manual Q are:

• Part 1 - Airflow Basics

• Part 2 - Fan Performance

• Part 3 - Fan & Duct System Interface

• Part 4 - Creating Comfort Using Manual T

• Part 5 - Duct Sizing Methods

Understanding Manual Q, as well as the other training packages in the HVAC Essentials series, can be purchased at (look under the HVAC Essentials logo or in Training CDs & DVDs) or by calling 888-290-2220.
