SHM 108 - Advanced Mechanical Drawing

 
Description
This is a course in advanced mechanical drawing and Heating, Ventilation and Air Conditioning (HVAC) applications. Students receive instruction on oblique, isometric and perspective drawings. Students practice these techniques extensively by creating drawings used in design and fabrication of HVAC systems.

1. Plan a drawing project with specific object or system constraints and limited space.
2. Project section views of truncated spherical objects.
3. Draw a product or series in oblique, isometric or section view with precision.
4. Create an accurately dimensioned isometric or oblique drawing of a given sheet metal object.
5. Explain the difference between pressure-dependent and independent variable air volume (VAV) control boxes.
6. Choose the right type of VAV box based on a floor layout blueprint and human occupancy.
7. Predict potential problems in a VAV control box system using an engineer’s drawing.
8. Select a suitable model of control box based on cubic feet per minute (CFM) requirements and manufacturer submittals.
9. Define friction loss and aspect ratio in airflow systems.
10. Explain the differences in duct sizing methods, focusing on CFM, velocity and equal friction principles.
