R427A refrigerant – lowest GWP of all R22 replacements

Refrigerant R427A (sold under the name Forane) is an HFC mixture which is suitable to serve as a replacement gas in various R22 applications in low, medium and high temperature cooling and air conditioning units. In operation, the cooling power drops by about 5% but the efficiency improves by 5–10%. Due to R427A being a mixture refrigerant, its temperature drift is high.

R427A boasts the lowest GWP

R427A boasts the lowest GWP of all refrigerants used as replacements for R22. Many other drop-in refrigerants are also available on the market. They can be used as replacement refrigerants in old R22 plants. All of these refrigerants are mixtures in which the most common main components are R134a and R125. Other drop-in refrigerants include R417A, R422A, R422D and R424A (Kianta 25 May 2008 and VTT bulletin 2548, 2010).

Applications and use

R427A is used for a diverse range of applications in industry, commerce and residential buildings as well as households. Retrofitting is fast and requires no expensive equipment replacements.

In terms of its cooling power, performance, mass flow, operating pressure and power consumption, it corresponds to R22. In addition to this, it boasts lower discharge temperatures, which extends the equipment’s life span.
