CO2 at atmosperic pressure = frozen dry ice.
CO2 at 21°c = >58 Bar
CO2 generally contains more water than Nitrogen.

You can do it, but unless you have a good reason to flush the system with liquid CO2 nitrogen sounds like a better option.

Yes you can clean the pipe but it hard cause the co2 is solid state at atm pressure. And if you just clean it for same kins of gasses to use there is no problem. IF you doing it if the main ref. gasses is another one ex. R410 then you got a problem delivery faster than light. CO2 is sligtly acid and corrord the compressor and other places than contain cupper. That why compressor is made cupperfree cause its break down the cupper and also that layer round the wire in compressor to protect if from shortcut. Hopefully it got some idea eevn my bad eng :-)

It will be dry. But will it be clean?
