R22 air conditioning refrigerant, alias R-22, difluoro-monochloromethane, Freon 22, F-22,HCFC-22
R22 refrigerant is used in reciprocating compressors and is used in household air conditioners, central air conditioners, mobile air conditioners, heat pump water heaters, dehumidifiers, freezing dryers, cold storage, food refrigeration equipment, marine refrigeration equipment, industrial refrigeration, commercial refrigeration, freezing condensation units, supermarket display cabinets and other refrigeration equipment;R22 is also widely used as a raw material for polytetrafluoroethylene resin and an intermediate for the gas fire extinguishing agent R1211, as well as a physical foaming agent for polymers (plastics). It can also be used as aerosol propellants for pesticides and spray paint. It is a basic raw material for the production of various fluorine-containing polymer compounds.
R22 air-conditioning refrigerant is the most widely used medium and low temperature refrigerant today. It is mainly used in household air conditioners, commercial air conditioners, central air conditioners, mobile air conditioners, heat pump water heaters, dehumidifiers, freeze dryers, cold warehouses, food freezing equipment, marine refrigeration equipment, industrial refrigeration, commercial refrigeration, freezing condensation units, supermarket display cabinets and other refrigeration equipment. Difluorochloromethane can also be used as a raw material for the production of polytetrafluoroethylene resin and an intermediate for fire extinguishing agent 1121, as well as a physical blowing agent for polymers (plastics). Juhua R22 is one of the most widely used R22 refrigerant brands in China.

Alternatives & Matched Lubricant
Under the Kigali Amendment HFC phase-down, the following alternatives can be evaluated (R22 itself remains legal to use); the final selection must match the application, system pressure and lubricant compatibility.
- Alternative refrigerants
- R32, R410A, R407C, R454B or hydrocarbon R290
- Matched lubricant
- mineral oil (not interchangeable with POE used by R407C/R410A)
Alternatives are a selection reference only; the equipment manufacturer's requirements and local regulations prevail.
GWP comparison: R22 vs. alternatives
Side-by-side comparison of R22 and its alternative refrigerants on the IPCC AR4 (GWP100) basis.
| Refrigerant | GWP100 | ODP | Safety class | Chemical family | GWP change |
|---|---|---|---|---|---|
| R22 | 1810 | 0.055 | A1 | HCFC | Baseline |
| R32 | 675 | 0 | A2L | HFC | ≈ -63% |
| R410A | 2088 | 0 | A1 | HFC blend | ≈ +15% |
| R407C | 1600 | 0 | A1 | HFC blend | ≈ -12% |
| R454B | 466 | 0 | A2L | HFO/HFC blend | ≈ -74% |
| R290 | 3 | 0 | A3 | HC | ≈ -100% |

Regulatory and compliance status (R22 / Chlorodifluoromethane (HCFC-22)) — phase-out in progress
R22 (Chlorodifluoromethane (HCFC-22)) belongs to the hydrochlorofluorocarbons (HCFC), with an ODP of 0.055, and is a Class II controlled substance under the Montreal Protocol, currently subject to the global phase-out schedule. Developed countries halted production and import in 2020; developing countries (including China) are advancing according to the schedule, with servicing stock tightening year by year. The following are the regional status as of 2026.
EU
- RegulationOzone-Depleting Substances Regulation (EC) 1005/2009
- StatusVirgin HCFC no longer placed on the market
- ServicingUse of reclaimed product permitted until 2030 (for some equipment types)
- For R22No supply of virgin product; servicing must use reclaimed product and must be performed by certified personnel
US
- RegulationClean Air Act Title VI + SNAP program
- StatusProduction and import of virgin HCFC halted from 2020-01-01
- Existing stockReclaimed product can be used for the maintenance of existing equipment
- For R22Only reclaimed product available; supply and prices continue to tighten
China
- RegulationRegulations on the Administration of Ozone-Depleting Substances (2024 revision) + National Phase-out Plan
- Schedule67.5% baseline reduction by 2025, 97.5% by 2030, with only a minimal amount retained for servicing use after 2040
- QuotaAnnual quota licensing for production and use, decreasing year by year
- For R22Supplied within quota; procurement must be filed; servicing use given priority
- Domestic procurement qualificationMust be filed in the “Ozone-Depleting Substances Information Management System”; suppliers must verify the filing
Japan
- RegulationOzone Layer Protection Act + Act on Rational Use and Proper Management of Fluorocarbons
- StatusHCFC is essentially abolished, with only reclaimed product in circulation
- For R22No supply of virgin product; must be retrofitted or replaced
Other countries and regions (grouped by the Kigali Amendment)
Apart from the four columns of EU / US / China / Japan, the global 170+ Kigali parties all comply under the A5 (developing countries) / non-A5 (developed countries) groupings of the Montreal Protocol, and none impose equipment-level bans. The grouping determines the HFC reduction pace and is unrelated to geography — for example, the Middle East Gulf and India belong to A5 Group 2, while Brazil, Mexico and Chile belong to A5 Group 1 (same group as China). The table below is a quick reference for the groupings of major markets:
| Grouping | HFC reduction pace | Major countries / regions (representative) |
|---|---|---|
| A5 Group 1 (developing countries, including China) | 2024 freeze → 10% reduction by 2029 → 30% by 2035 → 50% by 2040 → 80% by 2045 | Brazil, Argentina, Chile, Colombia, Peru, Mexico, South Africa, South Korea, Thailand, Indonesia, Malaysia, Vietnam, Egypt, Nigeria, etc. (about 140 countries in total) |
| A5 Group 2 (high-ambient-temperature group, HAT) | 2028 freeze → 10% reduction by 2032 → 20% by 2037 → 30% by 2042 → 85% by 2047 | India, Bahrain, Iran, Iraq, Kuwait, Oman, Pakistan, Qatar, Saudi Arabia, United Arab Emirates |
| Other non-A5 (developed countries, except EU/US/Japan) | 85% reduction by 2036 / reduced to 15% by 2050 | Canada, Australia, New Zealand, Switzerland, Norway, United Kingdom, Russia* (first two steps delayed: 5% by 2020, 35% by 2025), etc. |
For R22: a controlled substance in the phase-out process, with supply tightening year by year and prices rising. For the complete list of Parties and groupings, refer to the UNEP Ozone Secretariat (data version 2026.09).
