Now that the battle regarding ozone depleting potential (ODP) refrigerants has ended with the phaseout of CFCs and HCFCs, the fighting has shifted to issues related to the global warming potential (GWP) of the remaining and newly developing refrigerants.
The attention being paid to so-called natural refrigerants is showing a shift toward hydrocarbon refrigerants, even as CO2 gains a stronger foothold and ammonia maintains a high profile. But, whether or not there will be a dominant natural choice remains unclear even in Europe, much less North America.
As I’m writing this, the Diane Rehm Show on National Public Radio (NPR) has just aired a segment called “Who Benefits from College and Why.” One major component was who should go to college and who should go into a trade.
The importance of ongoing HVACR education involves both the getting and the giving. So there is a need for those who want to learn, and for those who understand that learning didn’t end when they left the high school, college, or vocational school classroom and lab.
When it comes to R-744 (CO2) as a refrigeration refrigerant, things seem to be more stable in stationary usage than in transportation applications. In the latter, the European automotive sector is looking beyond HFC for refrigerants in air conditioning.
“Now Hiring! Freezer Salesman in United States.” Well, there’s a new one for me. Usually at trade shows, somewhere in a booth might be a small sign saying, “Manufacturer representatives wanted.” The exhibitor in question also wanted to make it clear that there were openings for folks willing to bring attention to their line.
Inroads regarding natural refrigerants have been reported — and will continue to be reported — in The NEWS. I recently returned from the International Institute of Ammonia Refrigeration (IIAR) Conference in Colorado Springs where ‘natural’ was — naturally — the topic.
