Substitutes for R404A and R507A

For futher information and alternatives see Refrigerant Report A-501.

"Low GWP" alternatives for HFC refrigerants (status as of 09.2020) - further data: Refrigerant data
①: The relatively low GWP of R134a allows its use also on longer term.
②: lower volumetric refrigerating capacity than reference refrigerant
③: AR4: according to IPCC IV // AR5: according to IPCC V – time horizon 100 years
④: rounded values
⑤: total glide from bubble to dew line at 1.013 bar (abs.)
⑥: development product
