I’m an ammonia refrigeration guy, learning a little about CO2. I’m not an expert on HVAC because it has not been my career discipline. I don’t know much about most of the new blends. I do know basic refrigeration systems and how they function.
Some of the questions don’t make sense with regard to basic refrigeration. Also, some of the questions have two answers, and some don’t make sense.
I have commented on questions I have questioned, but I’m not sure anyone actually reads the comments and considers making changes.
