Big Changes In The HVACR Industry

As technology continues to grow in every sector, so it continues to do so in the HVACR industry. HVACR, which stands for heating, ventilation, air conditioning, and refrigeration, is an industry that relies on trained technicians to effectively function, which is why educators and other professionals must always be looking for better ways to train the incoming generation’s technicians.

Staying ahead of the curve is tough, especially considering the advent of computer technology. While the fundamentals and the basics of HVAC systems have not changed, the introduction of new technologies has made the learning curve for technicians and providers much steeper than it used to be. Formerly speaking the manufacturer controlled almost all of the equipment the same way. These days, however, high-end equipment continues to throw curve balls at HVAC instructors: thermostat wires are out, data highways are in, educators say, and the difference between pieces of equipment made by different manufacturers continues to grow.

Making sure that trained technicians – or technicians-to-be – know their stuff is becoming more difficult, professionals and educators have identified a few ways to maintain their edge. While it may sound trite, keeping it simple is one way to eliminate problems before they begin. As the systems and controls for HVACR systems become more complex, educators are realizing how crucial it is to rely on the fundamentals during the training process. Newcomers may be eager to move past the intro stuff and work on higher-tech projects, but without a foundation in the basics, many students will not have that information to fall back on.

The ways that new technicians learn have been changing, too. Although the majority of classes are still in person, the growth of online classes has changed the way that many instructors design and implement their curriculum. Still, one thing is certain: fundamentals are essential. This is because while our methods of heating will continue changing, the physics of thermodynamics and electrical theory will always be the same. The complexities of our changing HVAC products notwithstanding, heat will continue to flow to cold, superheat and subcooling remain foundational concepts, and technicians should have an understanding of psychrometrics. Other fundamentals, like electronics and a basic understanding of math, have been touted by experts as being the keys to understanding complex issues. While having an eye toward innovation and the hottest new developments is important, they say, new technicians would be best served to remind themselves that having a solid grounding in the basics is the surest way to success in the field of heating, ventilation, air conditioning, and refrigeration.

The Importance Of Learning The Fundamentals Of HVAC Systems

As the advancement of technology continues within the HVACR industry, a number of educators are scuffling to come up with innovative methods of making sure the new generation of service technicians is fully equipped with the necessary skills, knowledge and attitude to stay on par with the existing crop of trained technicians.
Systems, controls and just about everything that is associated with an HVAC system continue to become more and more complex as technology advances. As a result, a number of HVAC instructors are taking steps to ensure that they impart knowledge on the fundamentals as it relates to the training of current technicians and students.
A number of students seem to have the desire to learn only about the section of the training program that addresses the higher technological aspects of things and seem to have little or no interest in learning the fundamentals and the basics of HVAC systems. However, eliminating this aspect would water down the importance of the fundamentals and basics, which are very effective when used as a base on which more complex knowledge is built. Taking this approach to training future HVAC technicians will assist in solidifying the basis on which they can fall back.
It is extremely important that students are taught the fundamentals and that they learn them well. Technological advances have not resulted in any major change where electrical theory and the physics of applied thermodynamics are concerned. Irrespective of the intricate and sophisticated changes that are made to the HVAC and controls systems, they are all rooted in fundamentals that remain unchanged. Psychrometrics is important, the flow of heat goes from hot to cold and subcooling and superheat are essential concepts. The student who later encounters a complex and innovative system that has a problem, will find that his or her capacity to apply the well-learned set of basics and fundamentals remains the basis of success within the HVACR industry.

Trained technicians who are working within the industry have found that having sound knowledge of fundamentals in areas such as basic math, basic applied thermodynamics and electronics have been the key factor as it relates to the ability to understand the most complex issues. Being able to apply fundamental knowledge to new systems and products will open doors to staying on top in the industry, regardless of how complex the task. In essence, the better trained HVAC contractors are, the more efficient and reliable they will be.
