So far it has been a problem for scale. There are very few consumer appliances that use CO2 as a refrigerant. I can think of 1 right now - and it's 3x the price of it's alternative that uses traditional refrigerant.

They’re also more efficient, but more expensive. So I wonder how much of the price differential is the refrigeration loop, and how much is using more expensive processes to offset the lower tonnage for the system.
- danans 4y agoMost new technology heating and cooling systems are expensive because they serve the rich eco-nerd and commercial markets, both of which are willing to pay a premium for the real benefits of the technology. Hopefully the recent pro heat-pump moves across Europe and the US Administration's invocation of the DPA to support domestic heat pump manufacture will push this stuff out to the mass market instead of just in the houses of the wealthy. EVs are just now breaking out of that pattern, only after competitive pressure from companies like Hyundai, Kia, VW, and GM who have made nearly affordable EVs.
