HVAC Systems

When choosing a HVAC college program, the first thing that you must ascertain is that the destination college you have chosen is an accredited one. This is ultra important, as it means that the training provided 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, which means you will get one on one help from the program teachers. The best colleges teaching HVAC courses will also have an on college science lab 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 if they provide any flexibility in time-managing classes for students with external jobs, and also how you could go about procuring financial aid, if you might need it.

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.
