VOA 801 - Commercial HVAC Systems

5.6 Continuing Education Units (CEU). This course is not for Credit(s).

This course is designed to enable the student to explore the technology used in commercial, institutional, and industrial cooling systems. Topics to be covered include an analysis of system performance and diagnosis of problems; examining equipment such as reciprocating and centrifugal chillers, absorption systems, cooling towers, and fans and air handlers; and psychometrics, pressure-enthalpy diagrams, and commercial load calculations. Prerequisites: VOC 952 or AIRC 205, VOC 953 or AIRC 210, VOA 654 or ELEI 101, and VOA 656 or ELEI 201 or approval of program coordinator.

Course Objectives:

Upon completion of this course, the students should be able to:
1. identify the components of a large commercial cooling system;
2. describe the operation of a chiller/cooling tower/pump system;
3. relate psychometrics, pressure-enthalpy diagrams, and commercial load calculations to commercial air conditioning processes;
4. explain the composition of acceptable air quality;
5. explain the relationship between pressure and temperature;
6. demonstrate the ability to correlate the gas laws as they relate to HVAC; and
7. explain the difference between conduction, convection, and radiation.
