Can we use CO₂ in our fridges & AC's?

Could we use carbon dioxide as a replacement for the refrigerants we use in fridges, freezers, as well as the air-conditioning units in our homes and cars?

Process with Pat is the place to come for perspective and to ask stupid questions. I want you to leave more knowledgeable, confident, motivated, and most importantly, curious. I also want to invigorate a field that seems tired and uninspiring, at least if you get your perspective from internet forums. These are not lectures. This is a place for you to leave thinking “Oh! That’s why...”

This channel is not only for chemical engineers - anyone who works with processes should be able to find something of value here.
