HVA 2351 HVAC Systems & Controls

Theory and techniques for the control, troubleshooting, commissioning and operational parameters of a variety of systems used in today's buildings. This course emphasizes control strategies for energy efficiency and indoor environmental quality as directed by current standards for commercial and industrial HVAC systems. The control portions of this course begin with basic control elements and theory and continue with instruction regarding the BACnet, Lonworks, and ModBus protocols. The course prepares the student for a major installation and commissioning project using state-of-the-art equipment. Three classroom, six lab hours per week.

Prereqs: HVA 1301 and HVA 1352 


  • Apply industry standards to the complex problems of room air distribution, and space ventilation for proper health, safety and comfort of building occupants.
  • Using a defined control sequence, develop and program the controller, calibrate all control system components, document system behavior, and tune the control loop for a model building.
  • Develop a written strategy defining the operation of an HVAC system 24 hours per day, 365 days per year. The control strategy will be sufficient from which to develop the control system programming.
  • Perform psychrometric analysis, select secondary system components, and identify problems with system layouts and installations.
  • Analyze pumping strategies, describe system pressurization strategies, select secondary equipment, and identify problems with system layouts and installations.
  • Define and, where appropriate, calculate a host of control system parameters such as gain, dead time, and sensitivity. Identify control system components and show them in a schematic and block diagram.
