In this issue of The ACHR NEWS, the DOE considers a proposal to bump up efficiency standards and contractors use VR technology in training and sales. We also discuss proper compressor function, the DPA's affect on the geothermal industry, difficulties obtaining company vehicles, and electrification through commercial HVAC retrofits. Also in this issue: Calculations for temperature glide, supermarket refrigeration installs, troubleshooting a refrigeration system with multiple issues, and how to fight off "efficiency vampires."
Check back throughout the week for additional content.
Two major HVAC industry organizations have weighed in on a DOE proposal that would phase out noncondensing gas furnaces for consumer use beginning in about six years.
Since President Joe Biden invoked the DPA back in June 2022, HVAC-related energy efficiency incentives and renewable energy technology, have made their way into the spotlight. Many of those who work in the geothermal industry have been “waiting for this day” for decades.
Since the COVID-19 pandemic struck nearly three years ago, automobile manufacturers have had trouble getting many of the parts — computer chips especially — required to assemble the vans and trucks that field-service businesses use daily.
There is a lot that goes into being a successful HVAC contractor. However, like anything else, sometimes it is best to boil it down to the core of it: whoever has the best people wins.
Electrification presents a prime opportunity for contractors to deepen their relationships with customers who are looking for gas-fired heating alternatives. But they must first understand how different factors could influence the type of new system needed for an application.
The HVACR industry will soon be using low-GWP refrigerant blends, some of which have a temperature glide when evaporating and condensing. As these refrigerant blends change phase, there’s a change in their composition, which technicians must be able to calculate while in the field.
In an informative session at the NASRC’s Sustainable Refrigeration Summit, Publix and Coborn’s shared the pros and cons of incorporating CO2 refrigeration systems into their stores.
Repairing refrigeration systems can be challenging, especially when a system has multiple problems. Technicians should have patience during the troubleshooting process, as it is easy to rush to an early conclusion.
