Refrigerants - Environmental Properties
Comprehensive datatable of refrigerant types with their environmental properties, ozone depletion potential (ODP), global warming potential (GWP), chemical formulas, and typical applications.
| Refrigerant | Chemical Formula | Boiling Point (°C) | GWP | ODP | Description | Applications |
|---|---|---|---|---|---|---|
| Ammonia | NH3 | -33 | N/A | N/A | Efficient refrigerant used in industrial applications. Highly toxic with penetrating odor. | Large industrial plants |
| R-11 | CCl3F | N/A | 4000 | 1 | Single chlorofluorocarbon (CFC). High ODP and GWP. Banned in EU. | Commercial plants with centrifugal compressors |
| R-12 | CCl2F2 | -29.8 | N/A | N/A | Non flammable, non corrosive, non toxic, stable. Single dichlorodifluoromethane. | Small plants, automotive, medium temperature refrigeration |
| R-22 | CHClF2 | -40.8 | 1700 | 0.05 | Hydrochlorofluorocarbon (HCFC). Low ODP, modest GWP. Phase out by 2010 in EU. | Air conditioning, low/medium temperature refrigeration |
| R-134a | CH2FCF3 | N/A | 1300 | 0 | Hydrofluorocarbon (HFC). No ODP, modest GWP. R-12 replacement. | Automotive, stationary A/C, medium temp refrigeration |
| R-290 | C3H8 | N/A | 3 | 0 | Pure propane hydrocarbon. Extremely low GWP. Highly flammable. | Environmentally safe applications (with safety considerations) |
| R-407C | HFC blend (R32/R125/R134a) | N/A | 1610 | 0 | Ternary blend: 23% R32, 25% R125, 52% R134a. No chlorine content. | Modern refrigeration systems |
| R-410A | HFC blend (R32/R125) | N/A | 1725 | 0 | Binary blend: 50% R32, 50% R125. No chlorine content, no ODP. | Modern refrigeration systems |
| R-417A | HFC blend | N/A | N/A | 0 | Zero ODP replacement for R22. Drop-in compatible. | Retrofit and new equipment |
| R-500 | CCl2F2/CH3CHF2 blend | -33 | N/A | N/A | Blend: 73.8% R-12, 26.2% R-152a. ~20% more capacity than R-12. | Systems requiring higher capacity |
| R-502 | CClF2/CClF2-CF3 blend | -45.6 | N/A | N/A | Blend: 48.8% R-22, 51.2% R-502. Non flammable, non toxic, capacity comparable to R-22. | High capacity refrigeration |
