HVACR Industry Instructors Try to Keep Pace With Technological Advancements
Currently, the HVACR industry is undergoing many technological advancements. As a result, HVAC instructors are struggling to devise new methods to ensure that the new era of service technicians has the relevant expertise. In the past, even when new furnaces were introduced, there were only a few different kinds of control boards that were used by all manufacturers. Thus, while there was lots of different equipment to repair, it was all basically controlled in the same way. Hence, in the old days, maintenance and repairs were reasonably straightforward. Nowadays though, manufacturers have adopted the use of high end equipment. This is based around data highways, rather than thermostat wires. Such proprietary technology is much harder to service, if you are not the dealer for the equipment. With the design, controls and virtually everything related to HVAC systems becoming more complicated, many teachers are going back to basics to train the current crop of tech students. The physics of electrical theory and applied thermodynamics never changes. Warm air flows to become cold, subcooling and superheat are vital principals, and psychrometrics is essential. Students faced with the task of repairing a new, complicated system will find their ability to implement the fundamentals
