R32 Freon 20 lb. Jug for AC Mini Split Systems & Central HVAC

R32 FREON SDS SHEET

R32 FREON (difluoromethane) is a popular, single-component, low-GWP refrigerant increasingly used in new residential and commercial air conditioning systems, replacing R410A due to better energy efficiency and environmental performance. It is classified as an A2L refrigerant (mildly flammable), requiring specialized handling, with a Global Warming Potential (GWP) roughly one-third lower than R410A. 

Key Information on R32 Refrigerant

• Environmental Impact: R32 has a GWP of 675 (significantly lower than R410A's 2088) and zero Ozone Depletion Potential (ODP), offering a more sustainable choice.
• Performance: It is a single-component refrigerant, allowing for easier charging in both liquid and gas phases, with no risk of composition changes (fractionation). It is highly efficient, often increasing system efficiency by up to 10%.
• Safety Classification (A2L): Classified as mildly flammable, R32 is not easily ignited by static or sparks, but requires safety measures against ignition sources.
• System Requirements: R32 systems operate at similar pressures to R410A but may require different tools and training for installation and servicing.

Refrigerant Replacement: It is rapidly replacing R410A in split systems,, and some heat pumps. 

• Key Takeaways for Technicians/Users:
  Requires a specialized refrigerant handling license for service.
  It is a single-component, making it easier to recycle and reuse,
  It is not suitable for retrofitting older R410A systems. 
• Common Uses
  Small air conditioning systems.
  Residential split-system heat pumps.
  Light commercial HVAC systems. 

Core Properties & Comparison
R32 stands out for its balance of efficiency and environmental safety compared to older refrigerants like R-410A and R-22. 

• Global Warming Potential (GWP): R32 has a GWP of 675, which is roughly one-third of R-410A's (2,088).
• Ozone Depletion Potential (ODP): It has an ODP of 0, meaning it does not damage the ozone layer.
• Single-Component: Unlike R-410A (a blend), R32 is a pure refrigerant. This makes it easier to recycle, reuse, and top up without shifting the chemical composition.
• Efficiency: Systems using R32 can be up to 12% more efficient than those using R-410A due to better heat transfer properties. 
• Safety & Handling
  R32 is classified by ASHRAE as A2L, meaning it is low-toxicity but mildly flammable. 
  Flammability: While it is harder to ignite than common fuels like propane, it requires specialized tools (e.g., spark-proof vacuum pumps) and handling by certified technicians.

Operating Pressure: It operates at similar pressures to R-410A but requires specific equipment rated for A2L refrigerants.

Not for Retrofit: R32 cannot be used as a "drop-in" replacement for existing R-410A systems; it must only be used in units specifically designed for it. 

• Market Transition
  Due to international regulations like the Kigali Amendment, manufacturers are rapidly shifting to R32. 
  Widespread Use: Over 370 million units have been installed globally as of 2025.
  Leading Brands: Companies like Daikin, Mitsubishi Electric, LG, and GREE are major adopters.
