HVAC Constant Air Volume

When you decide to pick a HVAC college program, the most important point that you must find out is that the choice of college you have chosen has the necessary accreditations. We cannot stress this point highly enough, as it means that the training program imparted will be at par with the standards specified by approved HVAC organizations.

The most prominent accrediting agencies for HVAC training programs are the NCCEA, the Partnership for Air-Conditioning, Heating, and Refrigeration, HVAC Excellence, North American Technician Excellence and Research, Environmental Protection Agency, and the Occupational Safety and Health Administration. You MUST select a college that has a minimum of at least one accreditation.

Smaller class sizes are also important, because then you will receive personalized help from the instructors. A good HVAC college will also have an onsite science lab with modern equipment. Visit the campus and get a feel of the place, the instruction rooms, the facilities and talk to the senior lecturers, if they are available. You should also find out if they provide any flexibility in time-managing classes for employed students, and how you should go about requesting financial aid, if you might need it.

HVAC design engineers face many choices throughout the planning process, perhaps few as crucial as that of fan equipment, a principal consumer of energy. This article will discuss options for improving energy efficiency when designing an HVAC system and selecting a fan.
