How about changes to 410A home air conditioner refrigerant and R-134 for autos? By way of example, 410A is a terrible refrigerant already. It requires higher operating pressures and is much harder to contain than R-22. It also is less efficient owing to much lower pressure drops between the suction and discharge of the compressor. It also is prone to excess liquid phase requiring a liquid trap that is often overwhelmed under certain conditions allowing liquid into the compressor and leading to either compressor damage or reduced life.
People who have no idea what they are doing need to stay the hell out of regulating people who do.
This is a massive racket of changing these coolants and equipment. It is actually more FRAUD.
There is so much wrong here at home to correct we have absolutely no reason to meddle in the Middle East. We are getting absolutely nowhere in the ME, just wasting time and money. It is more of Trump’s Folly to even think that blocking Iran from nukes for more than a short time without an outright take-over of Iran.
For my most recent mini-split AC purchase last year, I had to look everywhere and pay a little more to get a 410A unit. I don’t want to deal with any of the newer stuff & 410A is readily available & will probably be around for awhile.
