Refrigerants
General Information
When choosing a refrigerant,
different
aspects must be taken into consideration:
• Legislation (now and in the future)
• Safety
• Application envelope in relation to expected running conditions
• Compressor capacity and
efficiency
• Compressor manufacturer recommendations & Guidelines
Additional points could
influence
the
final
choice:
• Environmental considerations
• Standardisation of refrigerants and lubricants
• Refrigerant cost
• Refrigerant availability
R410A
R410A is a HFC blend (R32: 50%; R125: 50%) with a zero Ozone Depletion Potential (ODP=0) and a Global Warming
Potential of 1924/AR5 (2088/AR4). It is a near-azeotropic mixture with a temperature glide less than 0.2 K.
With its high net refrigeration
effect
coupled to a high density, the R410A has appeared in last decade to be the
preferred refrigerant for use in commercial air conditioners and heat pumps.
