HVAC Inlet Duct

When you decide to pick a HVAC college program, the first thing that you must find out is that your preferred choice of college you have chosen has the necessary accreditations. This is an extremely important factor, since it means that the training supplied will be at the required standard specified by approved HVAC organizations.

The premier accrediting agency 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 need to select that has at least one accreditation.

It is also important to try and find small class numbers, which means you will get one on one assistance from the program teachers. A good HVAC college will also have an on college science laboratory with modern equipment. Visit the campus and get a feel of the place, the classroom, the facilities and talk to the teachers, if they are available. Also find out whether they allow any flexibility in organizing classes for working students, and how you could go about researching financial aid, if you might need it.

Fan applications with airstreams of explosive or flammable particles or gases require spark-resistant system components for the safe handling of such airstreams. This includes components such as ductwork, dampers, filter devices, heating or cooling coils, and fans. This article presents practical considerations and methods of providing fans with varying types of Spark-Resistant Construction (SRC). The Air Movement and Control Association (AMCA) established a standard set of Classifications for Spark-Resistant Construction.

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.

Practically all air removed from a building is replaced by outside air at the same rate. Outside air will enter by any means available, when the inside air pressure is less than outside air pressure. This happens when exhaust exceeds supply systems capacity to replenish the building envelope with air. Possible consequences of this negative pressure differential are degraded exhaust system performance, loss of environmental control, adverse safety and performance effects on
