Refrigerator industry latest use of refrigerants2026-10-12
Company News | 2025-03-26 20:56:00
The common refrigerant used in commercial refrigerators and its latest refrigerant standards are as follows:
1. Common refrigerant types
1. HFCs (hydrofluorocarbons)
R-134a: has been widely used in low - and medium-temperature equipment, but the GWP is high (about 1430), is being phased out.
R-404A: Commercial cryogenic refrigerators are common, but have a very high GWP (about 3922) and face strict restrictions.
R-407 series: such as R-407C (GWP≈1774), used to replace R-22, performance is close to but environmental protection is still insufficient.
2. HFOs (hydrofluoroolefin)
R-1234yf: GWP < 1, environmentally friendly but flammable, suitable for new commercial equipment.
R-1234ze: Low GWP for medium temperature systems, gradually replacing R-134a.
3. Natural refrigerant
-R-290 (propane) : GWP≈3, highly efficient but flammable, requiring strict safety measures.
R-600a (isobutane) : common for household and small commercial use, GWP≈3.
- CO₂ (R-744) : GWP=1, suitable for cross-critical systems, high pressure operation requires special design.
4. Ammonia (R-717)
- For large-scale industrial refrigeration, GWP=0, toxic and flammable, requiring professional management.

Second, the latest refrigerant standards and regulations
1. Kigali Amendment
- Calls for a gradual reduction of HFCs, 85% by 2036 in developed countries and a freeze in developing countries by 2024.
2. Eu F-Gas Regulation (updated 2024)
- From 2025 onwards, the use of refrigerants with GWP≥150 in new equipment is prohibited (commercial refrigerators are affected).
By 2030, HFCs supply will be reduced to 21% of 2015 levels.
3. The US SNAP program
- High GWP coolants such as R-404A and R-507A are banned, and transitional alternatives such as R-448A (GWP≈1273) and R-449A are promoted.
4. China's refrigerant policy
- Accelerate the phase-out of HFCs from 2024, encourage natural refrigerants and HFOs, and progressively implement the Kigali goals.

Third, industry trends
Environmental protection priority: Low GWP (such as HFOs, natural refrigerant) has become the mainstream, and the application of CO₂ and hydrocarbon refrigerant has increased.
- Safety adaptation: Flammable refrigerant (such as R-290) needs to be equipped with explosion-proof design and standard updates.
- Energy efficiency: The new refrigerant needs to balance environmental protection and system efficiency, such as R-513A (GWP≈573) instead of R-134a.
It is recommended to pay attention to local regulations and choose a compliant and sustainable refrigerant solution.
