HVAC Systems

When you decide to pick a HVAC college program, the most important point that you must ascertain is that your preferred destination college you have chosen has the necessary accreditations. This is ultra important, as it means that the training program imparted will be at par with the standards 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 get one on one assistance from the instructors. The best colleges teaching HVAC courses will also have an onsite science lab with modern equipment. Before enrolling make sure you visit and explore the campus and get a feel for the place, the classroom, the facilities available and talk to the teachers, if they are available. You should also find out whether they allow any flexibility in time-managing classes for employed students, and also how you could go about requesting 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.
