Good paper about CO2

http://www.r744.com/knowledge/faq/fi...bell_paper.pdf

I just had a look at that paper, good stuff, CO2 is definitely the way forward. Though I've been wondering what changes are there to the components besides the compressor, being the pipe sizes/thicknesses, receivers, oil separators, fin-tube condenser tube thickness? Surely there must be changes to the system in terms of pipes and heat exchangers?!

good share thank peter,not my field but iam sure it wont be long before we see C02 VRF's

I am not sure about the pipe but the fittings that I saw came from NDL. They have CO2 fittings.
