Is that true though? Better coolants, inverters / variable speed / scroll /swing compressors, insulation and mfg, etc. maybe for residential it’s less impactful

Is that true though? Better coolants, inverters / variable speed / scroll /swing compressors, insulation and mfg, etc. maybe for residential it’s less impactful, but refrigeration in general has better efficiency than 30 years ago.
- cortic 1y ago> Better coolants The Montreal protocol (1987) put us back into the dark ages with coolants for a while (both with CFC ban and later phase outs of HFCs). I suspect if you tested a refrigerator from 40 years ago they would give modern ones a run for their money... It was obviously a worthwhile sacrifice for the ozone layer though.
