Phase-out of R22 will start in the world. And the existing alternatives to R22 are not good in some application. The present status, analyzes problems and requirements for new environment-friendly alternative. Also advances an idea using R32 to replace R22 in household/commercial air-conditioning, compares and analyzes the thermophysical properties, environmental characteristics, safety, theoretic cycle performance, market availability of R32, R410A, R290 and R1234yf. It shows that R32 is an electric choice considering carbon dioxide emissions, safety, energy-saving and market availability, and is an ideal refrigerant alternative to replace R22.
