Comparing R407C and R410A as Alternatives for R22 2016-10-14 11:20:55  Quote:制冷快报

R407C and R410A R407C is a non-ozone depleting blend of three HFC refrigerants (R32, R125, R134A) and was designed to match as closely as possible R22 pressure and performance to allow a smooth transition from R22 to R407C. It exhibits performance characteristics similar to R22. R410A is a non-ozone depleting blend of two HFC refrigerants (R32, R125) and was designed to provide benefits in efficiency and system size by increasing system pressure and taking advantage of thermodynamic and transport properties. It exhibits higher pressures and refrigeration capacity than R22. The properties and performance of R407C and R410A are compared in Table 1.
