Refrigerant and Refrigerant Oil Characteristics
Change of
The following chart shows the relationship between the composition balance (mixing ratio by weight) and
Composition and characteristics (pressure, combustibility, GWP, COP).
Characteristic in
Refrigerant
Note: R-407C [R32/R125/R134a (23/25/52wt%)]
When the composition of a refrigerant changes, characteristics such as COP and pressure also vary, as
shown above.
For example, if the percentage of R32 increases in the R-407C refrigerant (that is, when the mixing ratio
moves up toward R32 from point (1) position), the refrigerant's COP and pressure characteristic increase.
