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.
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.
While natural refrigerants start to slowly — and cautiously — gain a foothold in North America, their impact is more forceful almost everywhere else. What do other countries have to say about this?
Two recent refrigerant developments focus on CO2 and HFOs. One relates to CO2 in refrigeration; the other is an announcement of an HFO in air conditioning.
In response to the accelerated phaseout of HCFCs, Indianapolis-based refrigerant producer ICOR International has expanded its refrigerant reclamation operations.
Recently, there has been a lot of talk about natural refrigerants such as CO2 and hydrocarbons gaining a stronger foothold. Yet much of the talk is related to the possible phasedown of HFC production. And currently, while there may be some talk about a possible phasedown, no actual action seems to be taking place.
The expanding applications for ammonia in commercial refrigeration are being demonstrated in several recent projects involving heat pumps. What constitutes one possibility for efficient management of heat energy?
Two new reports that provide detailed studies of refrigerants have recently been released. The research is evaluating how newer refrigerants — ranging from HFC and HFO f-gases to natural refrigerants such as ammonia, CO2, and HCs — stack up against the current crop of popular refrigerants.
During the brewing process, certain temperatures have to be maintained. For the amber nectar to succeed, breweries need refrigeration solutions tailored to their processes and individual requirements.
