    I wouldn't mix them if thats what you ment.If you want more specific readings and details,refer to the P-T Chart on the refrigerants.I take it its an Air Conditioner you're working on?

    G'day, R22 is HCFC azetrope, R-407C is HFC non-azetrope meaning it has a temperature glide as its a blend of gases and must be liquid charged. It also requires polyester oil. R-407C is one of the replacements for R22 in most new A/C equipment and chillers from 10kw to 200kw.

    hassan,

    If you are inquiring about converting from R-22 to R407C follow this link to Copelands AE bulletin. The first paragraph will help with your decision.
