More than 150 HVACR professionals explored the topic of building performance, the transition to home performance contracting, and more at Air Conditioning Contractors of America’s (ACCA) inaugural Building Performance Forum, Oct. 9-10, in Austin, Texas.
According to a recent AHR Expo survey sent to more than 1,000 HVACR manufacturers worldwide, 70 percent of the respondents expect the economy to be better in 2013 than in 2012. In fact, 15 percent of the manufacturers expect a “much better year.”
Now, more than ever, the industry has been looking for alternatives to R-22 to keep the huge existing base of R-22 equipment up and running. More reclamation has been one option. But at the same time, attention is being paid to a large number of HFC refrigerants that can be retrofitted into R-22 equipment.
Because no one HFC refrigerant can be retrofitted efficiently into the entire range of R-22 equipment, a wide and sometimes changing variety of HFCs have entered the market. The NEWS contacted a number of refrigerant manufacturers asking them to discuss some of their most popular HFCs for R-22 retrofits.
There will always be a time when the evaporator sees a light load and the TXV may lose control of its evaporator superheat due to limitations of the valve and to system instability. What do you do then?
Two recent projects demonstrated successful retrofitting of HFC refrigerants into existing HCFC-22 systems. These projects, which were highlighted by Arkema, detail the processes with regard to HFC-427A in refrigeration and air conditioning applications.
“We aren’t green, we’re gold.” That was the message being sent from speakers and trainers at the 2012 International Ground Source Heat Pump Association’s (IGSHPA’s) technical conference and expo. What else happened at the conference?
It was 1987 and while the Copeland Scroll technology was entering the HVAC marketplace. The technology ushered in a new phase of energy efficiency for the residential HVAC industry and also became a standard in the commercial and refrigeration sectors.
An esteemed panel of energy-efficiency aficionados recently met inside Philadelphia’s Navy Yard for Danfoss’s 18th EnVisioneering Symposium, “Building Blueprint for a Clean Energy Future.” What happened during the symposium?
