SHM 204 - CAD and HVAC Design

Credits: 4
2 Lecture Hours 4 Lab Hours

Prerequisites: MAT 191  

This course is synthesis course on design of HVAC systems and creating shop drawings using CAD software. Students will apply skills learned in mechanical drawing and mathematics to create HVAC design drawings which meet design criteria as spelled out in the SMACNA and ASHRAE design manuals.

Learning Outcomes
Upon successful completion of the course, the student will:

  1. Identify an HVAC system type given an engineering drawing of the system showing key components.
  2. Compare and contrast types of HVAC systems as to efficiency for space and cost.
  3. Predict changes in airflow within an HVAC system.
  4. Describe characteristics of airflow within a given HVAC system.
  5. Calculate BTU needed to make changes required.
  6. Explain principles of heat transfer.
  7. Define static, velocity and total pressure within a duct system.
  8. Predict changes in pressure within any given duct fitting.
  9. Calculate changes in rpm, static pressure and brake horsepower on a fan, given current conditions and the desired change in one condition.
  10. Create shop drawings for an HVAC system which include all necessary information and dimensions to fabricate and install the system as planned, meeting design criteria as spelled out by the design engineer and shop standards.
