There?s a lot of interest in CO2 systems, particularly in cars to replace HFCs.
Having spent my working life with the more traditional systems, it?s not a subject I?m knowledgeable about, so can anyone help me with a brief explanation of the process?
I?m making the assumption that the process is trans-critical. Is this so? If not how is the liquid stage managed?
What sort of pressures are we looking at?
Any help is much appreciated.
