Core Course Performance Objectives (CCPOs)

  1. Evaluate different types of air distribution systems and associated components. (CCC 2, 5; PGC 7)
  2. Apply techniques used to predict and measure air-flow. (CCC 2, 3, 6; PGC 4, 5, 7)
  3. Analyze actual and theoretical scenarios to ascertain load estimations, component location, and proper duct placement. (CCC 1, 4, 6; PGC 4, 7)

See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.

Measurable Performance Objectives (MPOs)

Upon completion of this course, the student will:

  1. Evaluate different types of air distribution systems and associated components.
    1. Compare duct components normally found in residential applications.
    2. Examine types of air duct configurations and their applications.
  2. Apply techniques used to predict and measure air-flow.
    1. Identify the types of air balancing instruments, and discuss their applications.
    2. Determine air-flow using the temperature-rise method.
    3. Gauge velocity pressure using an inclined manometer.
    4. Gauge system velocity pressure using a vane anemometer.
    5. Determine system cubic feet per minute (CFM) using a vane anemometer.
    6. Determine system CFM using the temperature-rise method.
    7. Adjust system diffusers to proper CFM using a velometer.
  3. Analyze actual and theoretical scenarios to ascertain load estimations, component location, and proper duct placement.
    1. Calculate round and square duct size when given the friction rate and required CFM.
    2. Determine duct velocity when given friction rate and duct size.
    3. Identify equipment, duct, and diffuser locations for residential applications.
    4. Calculate heat gain and heat loss for a typical residential application in accordance with Air Conditioning Contractors of America (ACCA) Manual-J (including duct distribution plan and equipment list).

Evaluation Criteria/Policies

The grade will be determined using the Delaware Tech grading system:

90-100 = A
80-89 = B
70-79 = C
0-69 = F
