Servicing

RE: Servicing

React to this Post

Is any information available about total maintenance costs of CO₂ systems? It would seem some costs should be lower such as not needing to recycle the refrigerant, easier purging of the system before filling it, leaks not being critical to repair, and lower cost of refrigerant. My interest is for passenger rail air conditioning and heat pumps.
