When choosing a refrigerant, different aspects
must be taken into consideration:
• Legislation (now and in the future)
• Safety
• Operating envelope in relation to expected
running conditions
• Compressor capacity and efficiency
• Compressor manufacturer recommendations &
Guidelines
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
The purpose of this guideline is to help
customers qualify compressors in the unit.
You are strongly advise to follow these
instructions. For any deviation from the
guidelines, please contact Danfoss Technical
Support. In any case, Danfoss accepts no
liability as a result of the improper integration
of the compressor into the unit by the system
manufacturer.
Additional points could influence the final
choice:
• Environmental considerations
• Standardisation of refrigerants and lubricants
• Refrigerant cost
• Refrigerant availability
The DSF compressors can be used with
refrigerant R32
and directives about the use of refrigerant of the
A2L safety group (EN378, EN60335). Outside
Europe refer to the local regulation
