Evaluation
(comparison with R22)
1. ODP (ozone destruction factor) : Indicated values are relative value with that of R11 as 1.
2. Temperature conditon : 50˚C
3. Temperature condition : 0/50˚C
4. Boiling point condition : Temperatures at which R-407C begin boiling under the atmospheric pressure

Non-azeotropic
Nonflammable
Pressure is approximately 10%
higher than that of R22.
Capacity is about the same. Since
it is non-azeotropic, it must be
handled with utmost caution.
(Mishandling causes the
composition to change.)
GWP (global warming factor) : indicated values are relative value with that of CO2 as 1.
(1 atm)
