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
R32
R32 is a pure HFC refrigerant with a zero Ozone Depletion Potential (ODP=0) and a low Global Warming Potential
(GWP: 677/AR5; 675/AR4).
R32 leads to higher discharge temperatures than R410A but it offers higher cooling capacities and better efficiencies
compared to R410A.
R32 is classified A2L with low flammability properties. Please refer to European regulations and directives about the
use of refrigerant of the A2L safety group (EN378, EN60335). Outside Europe refer to the local regulation
