Carrier built an entire line of R-22 centrifugal machinery in response to the 1990 Clean Air Act, the phaseout of R-11, and before R-134a had been totally accepted (oil miscibility problems, and they also had to tool up for ASME Stamp manufacturing capability). This lasted for a couple of years or more, then the total switch to R-134a was made. Carrier refused to change to R-123. Trane had not ratcheted up the political lobbying for R-123 initially, and was busy solving dissolving gaskets. They had decided that the hurdle of ASME Stamp production was too great, and decided to cast their lot with R-123 (still a low pressure refrigerant). There was just a small problem with it dissolving gaskets.
Unlike R-134a, however, R-123 first had serious Threshold Exposure Limits (why SCBA's are needed for leaks), and is still not free from Ozone Depleting Capability. However, once the lobbyists for ASHRAE and EPA tooled up, now we have ASHRAE Std 15 requirements that force refrigerant leak detectors and emergency ventilation in both cases, and the EPA "recognized" that stop-gap refrigerants were OK. Or, that the potential for high-pressure leaks of R-134a was just as dangerous as the health effects from R-123 (no one pointed out that R-22 had been around for decades). Eventually, even "Global Warming Potential" labeling was applied to R-134a cans in the Auto Parts Store - a perverted success of the lobbying effort.
It is interesting to note that global warming potential labeling has nothing to do with the R-134a gas itself. However, the refrigerant process with R-134a is slightly less efficient - inherently - so its use in refrigeration machines burns more energy which causes the release of more CO2 at the power plant(!), hence global warming. So, the can is labeled as such because of this seriously stretched logic (not really true anymore, anyway).
Meanwhile, releasing a can of R-134a into the atmosphere has zero effect on health, zero effect on Global Warming, and zero effect on the ozone.
It's a funny political world we live in. NOT.
Anyway, to answer your question - yes, there are some Carrier R-22 centrifugals around - maybe others I'm not aware of, too.
