With the introduction of computer controlled heating, ventilation, air conditioning, and refrigeration systems, increasingly advanced technology is required to control indoor climate conditions, production processes, and food preservation. The Associate of Applied Science in HVACR ET provides the in-depth knowledge and skills needed for a variety of challenging careers in this growing industry. The focus is on the basic operating principles of commercial HVAC.
What specialized courses are offered in HVACR ET?
Once students have completed the foundation courses, courses cover the topics of heating and ventilation, air conditioning, refrigeration, industrial ventilation, controls, system analysis and design using computers, project planning, and estimation.
Principles are presented in a step-by-step fashion by addressing the topics of refrigeration, heating and ventilation, distribution, filtration, and control as individual subsystems. Upper level courses tie the subsystems together to discuss how they interact, providing proper system operation. Lectures and problem solving activities are supported by laboratory exercises to give students first-hand experience in reading instruments, analyzing data, drawing graphs, and preparing written and oral reports.
