Not such a big COP.
Why then use CO2 and why not R507c for instance?

Hi,
I think carbon dioxide is an example of the natural refrigerants (beside ammonia; that's why they both are used in the cascade refrigeration systems) :) Its GWP is 1. R507 has GWP at the level of 3900. I think the difference lies here.
Best regards,
