HVAC Brake Horsepower

When you decide to pick a HVAC college program, the first thing that you must find out is that the destination college you have selected is an accredited one. We cannot stress this point highly enough, since it means that the training program provided will be at least as good as specified by regulated HVAC organizations.

The most prominent accrediting agencies for HVAC training programs is the National Center for Construction Education and Research, 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.

It is also important to try and find small class numbers, because then you will receive one on one attention from the instructors. A good HVAC college will also have an on college science lab with professional-grade tools. Before enrolling make sure you visit and explore the campus and get a feel of the place, the instruction rooms, the overall facilities offered and talk to the teachers, if they are available. You should also find out if they provide any flexibility in scheduling classes for students with external jobs, and also how you should go about procuring financial aid, if required.

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.

Technical Development Programs (TDP) are modules of technical training on HVAC theory, system design, equipment selection and application topics. They are targeted at engineers and Brake horse-power is the application rating for the compressor. In cases where the compressor kW is known:
