The June 8, 2015 ACH & R News featured an opinion article by Kyle Gargaro which asked the question, is your organization changing? If not the opine stated, it should be. The article quoted former NFL coach John Gruden who said, “When talking about teams and players: you never stay the same. You either get better or you get worse.” What about your organization? Are you prepared for the changes coming in this industry? Consider the following.
Another article in the same publication talked about the changes coming to condensing units. In an article by Ron Rajecki, he stated that if you are like most consumers, the condensing unit represents the “face” of your system – but big changes are coming to that face. While multistage condensing units have been around for some time now, variable speed compressors offer the ability to better match equipment performance with the needs of a changing load, according to Tom Archer, product manager for Carrier Corporation. Variable speed condensing units have enabled manufacturers to make drastic reductions in the overall size and weight of condensing units, sometimes by as much as 50% with the same efficiency rating is a traditional single speed unit. Archer also noted that communicating HVAC systems are becoming increasingly prevalent.
According to Farook Mohamad, director of product management for Rheem Manufacturing, US manufacturers have traditionally used the air side of the system to gain higher efficiencies. Therefore the size of heat exchanger surfaces have increased and more efficient fans and motors are being used. “We’ve kind of come to a crossroads in that the size of the equipment continues to increase, and the cost of materials goes up,” said Mohamad. “So, we are increasingly turning our focus to the refrigerant side of the system and going with variable speed compressors and drives to increase efficiency. On the air side, we are beginning to run into the law of diminishing returns.”
What does that mean for contractors? According to Mohamad, “Contractors are going to need to understand the technology and diagnostics the equipment is providing them. Training is going to be very important. ” Looking down the road, Mohamad said he expects consumer demand to drive more high-end products. Traditionally, the bulk of the industry has been built on minimum feature, minimum efficiency products but Mohamad thinks that’s going to change in the next five years because society is becoming more informed and tech savvy. “Everything is moving at breakneck speed,” he said. “Products are becoming more sophisticated and there is a general expectation that people want to be able to control and communicate with their appliances, and our industry is just catching up with it.”
