Advantages:
• cheap, widely available
• non-toxic
• high heat capacity: excellent medium for heat transport
• chemical stable: less material requirements
• low viscosity: low friction losses
Disadvantages:
• very low pressure, high specific volume, big installations needed (turbine, condensor, etc)
• high pressure drop to become a high enthalpy drop: expensive multi-stage turbines needed
• expansion has to start in the superheated area to avoid too much moisture content after expansion
• efficiency loss and limited suitability to waste heat recovery
