[6] R-410A was successfully commercialized in the air conditioning segment by a combined effort of Carrier Corporation, Emerson Climate Technologies, Inc., Copeland Scroll Compressors (a division of Emerson Electric Company), and ...
The energy efficiency and system capacity of systems designed for R-22 is slightly greater using R-22 than the available substitutes. [11] R-407A is for use in low- and medium-temp refrigeration. Uses a polyolester (POE) oil. R-407C is for use in air conditioning. Uses a minimum of 20 percent POE oil. R-407F and R-407H are for use in medium ...
Replacements such as R-32 and R-410A are being promoted as environmentally friendly but still have a high GWP. [88] A heat pump typically uses 3 kg of refrigerant. With R-32 this amount still has a 20-year impact equivalent to 7 tons of CO 2, which corresponds to two years of natural gas heating in an average household. Refrigerants with a high ...

Because of its reduced global warming potential (GWP), R-454B is intended to be an alternative to refrigerant R-410A in new equipment. [2] [3] [4] R-454B has a GWP of 466, which is 78 percent lower than R-410A's GWP of 2088. [2] R-454B is non-toxic and mildly flammable, with an ASHRAE safety classification of A2L. In the United States, it is ...
