HVAC Systems

When choosing a HVAC college program, the most important point that you must ascertain is that the choice of college you have chosen is an accredited one. We cannot stress this point highly enough, as it means that the training imparted will be at least as good as specified by professional HVAC organizations.

The premier accrediting agency for HVAC training programs is the NCCEA, which is 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 to one assistance from the program teachers. The best colleges teaching HVAC courses will also have an on-campus science lab with modern equipment. Visit the campus and get a feel of the place, the classroom, the overall facilities offered and talk to the faculty, if possible. Also find out whether they allow any flexibility in organizing classes for working students, and also how you could go about researching financial aid, if you are eligible.

For the HVAC units to function effectively, dampers are the most essential ones as it regulates the flow of air throughout the system. Whatever be your needs to make indoors warm or cool, HVAC dampers determines the air flow of the whole building and even separate sections also. Dampers can be set in order to close off the pipe or to control the quantity of air flow into rooms. It is easy to adjust the temperature and humidity of living rooms with the help of dampers. Large organizations and buildings benefit more by using HVAC dampers, as these are efficient in cutting off the energy costs, which is the important factor affecting the companys resources. The use of dampers reduces the monthly energy bills and so benefits house owners too.

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.

Facilities with air conditioning and refrigeration equipment are required under EPA regulations to have a refrigerant recovery plan in force in order to capture any of the harmful gas that might leak into the air. This plan is necessary because refrigerant gases contain hydrofluorocarbons, which cause severe damage to the ozone layer and promote global warming.
