Trade Math Three – Field Measuring and Fitting
Describes the techniques used for field measuring and layout of ductruns and fittings. Also provides practice in solving field measuring problems.

Air Systems
Reviews the operating principles, components, and applications of common air systems. Discusses constant volume systems, variable volume systems, variable temperature (VVT) systems, variable air volume (VAV) systems, and dual VAV systems.  

Principles of Airflow
Explains the basic principles of airflow and reviews how airflow is affected by duct size, shape, and fittings. Also reviews the components of an air distribution system.

Louvers, Dampers, and Access Doors
Discusses the different types of louvers, dampers, and access doors used in air distribution systems and reviews the standards that apply to them.

 

Comprehensive Plan and Specification Reading
Provides a case-study approach to learning how to use building plans and specifications to lay out, fabricate, and install HVAC systems. Allows trainees to proceed through the module as if they were working on an actual building project. Includes construction drawings.

Fabrication Three – Triangulation
Describes the principles of triangulation and how it can be used to measure ductrun fittings. Provides trainees with a variety of tasks to practice developing, laying out, and fabricating selected ductrun fittings.

Advanced Architectural Sheet Metal
Provides the opportunity to practice layout, fabrication, and installation of various architectural pieces. Makes use of items built in Fabrication Three–Radial Line Development.
