1. R407c has replaced R-22 as the preferred refrigerant for use in houshold air conditioner, bus air conditioning and train air condition
And so on.
2. R407c is a zeotropic hydrofluorocarbon blend of r32, r125 and r134a. The r-32 serves to provide the heat capacity. R-125 decreases
Flammability, r-134a reduces pressure.
