One key difference between R22 and 407C is their chemical composition. R22 contains chlorine, while 407C does not. This makes 407C a more environmentally friendly option, as it does not contribute to ozone depletion. Another difference is their boiling points. R22 has a boiling point of -41.5 °C, while 407C has a boiling point of -51.7 °C. R466A. This refrigerant, developed by Honeywell, is listed separately because its classification is A1. Also introduced in 2018, this refrigerant is composed of R32 (49%), R125 (11.5%), and R1311 (39.5%). It has a similar performance factor to R410a and was developed as a more direct replacement of R410a in new equipment. Replacement is also an opportunity to improve your organisation’s environmental credentials. Modern refrigerants, such as R32 and R410a, have a much lower impact on global warming than R22, while modern systems consume less energy and can considerably reduce your carbon footprint. In the United States, ozone-depleting substances (ODS) are regulated as class I or class II controlled substances. Class I substances, such as chlorofluorocarbons (CFCs) and halons, have a higher ozone depletion potential and have been phased out in the U.S.; with a few exceptions, this means no one can produce or import class I substances.
