R32 refrigerant is also known as difluoromethane and belongs to the
Difluoromethane, also called difluoromethylene, HFC-32 Methylene Fluoride or R-32, is an organic compound of the dihalogenoalkane variety.

Aiming for widespread use throughout the world, Daikin not only manufactures and sells R-32, but it also provides technical assistance in emerging countries in cooperation with governments and international organizations.
In fact, R-32 is a single component refrigerant, while R-454B is a blend that consists of nearly 70% R-32. R-32 has been safely used in over 160 million units in the US and around the world by more than 40 OEMs.
R32 refrigerant is also known as difluoromethane and belongs to the HFC family of refrigerant. This gas is poised to replace the other gaseous such as R-410A and R-407C as the preferred gas due to its lower Global Warming Potential. Its chemical formula is CH2F2.
Changes to the Dangerous Goods Legislation, effective in 2021, has new categories for A2L refrigerants. R32 is a synthetic greenhouse gas. If released to the atmosphere it can contribute to climate change. R32 is a flammable refrigerant.
R32 is a popular choice, due to its availability, performance and efficiency, but R454B and R452B also offer convenience and, potentially, low system qualification costs. Further alternatives are also entering the market.
Compatibility: R32 is compatible with existing air conditioning systems that use R22 and R410A, making it a suitable alternative for retrofitting existing systems.
No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
However, the mixture R32/R134a in the NRC will result in a better performance. The maximal COP can be improved in a range of 8–9% over that of the CRC, and the volumetric refrigerating capacity can be approximately increased by 9.5%.
R32 is a HFC refrigerant, used as a replacement for R410A in low temperature refrigeration and air-conditioning applications. This refrigerant is a preferred replacement for R410A in new equipment.
Potential Drawbacks of R32
Despite the growing popularity of R32 refrigerants, there are some potential drawbacks associated with its use. These include flammability and safety concerns and retrofitting and compatibility issues.
Only Section 608 certified technicians can purchase refrigerants intended for use with stationary refrigeration and air-conditioning equipment.
The Key Differences Between R22 & R32
R22 loses on both fronts. This gas has a medium ozone depletion potential, which is too high to be approved for any use. Meanwhile, its global warming potential is 1810. R32 has a zero ozone depletion potential and a GWP of 675.
Refrigerant Leaks
AC units manufactured since 2010 use R410A, and more recently, R32 refrigerants, both are virtually odourless. This means that a smell of rotten eggs is unlikely to be the smell of leaking refrigerant coming from your air conditioner itself.
First issue is miscibility with R32, because incumbent refrigeration oil for R410A is rather immiscible to R32.
For R32 model, use pipes, flare nut and tools which is specified for R32 refrigerant. Using of existing (R22) piping, flare nut and tools may cause abnormally high pressure in the refrigerant cycle (piping), and possibly result in explosion and injury. Thickness of copper pipes used R32 must be more than 0.8mm.
The GREE Sapphire R32 Single-Zone Mini-Split System is the pinnacle of GREE's innovation, offering unmatched efficiency and a sleek, modern design. Utilizing advanced R32 refrigerant, this premier mini-split system ensures superior energy efficiency and a reduced environmental impact.
Existing R410A pipework can be re-used when replacing older R410A units with new R32 units provided the interconnecting pipe size is not smaller than that recommended for the new system. Oil traps must be fitted to vertical suction risers where outdoor unit is above indoor unit.
You will, of course, need to ensure that any equipment you use includes an R32 compliant recovery unit, an R32 specific vacuum pump, a torque wrench set to the manufacturer's recommendations on your flare joints and for pipework, stick to material that is R410A rated, as this also suitable for R32.
LG leads the way with R32 refrigerant
Now builders can take advantage of the many benefits of R32 refrigerant for their homeowners with LG solutions and technologies as a refrigerant that reliably keeps homes warm and cool.
In the first half of 2024 we'll phase out our R-410A dedicated models and introduce -01 refrigerant versatile models, compatible with both R-410A and R-454B refrigerants.
R32 is a singlecomponent refrigerant, meaning it is not a blend. This simplifies system maintenance, allowing technicians to “top off” the system without having to fully recover and recharge the refrigerant. R454B, on the other hand, is a blended refrigerant.
