Environmental Impact of R32
Understanding the environmental impact of R32 refrigerant is essential for homeowners who want to make informed decisions about their HVAC systems.
Global Warming Potential of R32
R32 (difluoromethane) is notable for its low global warming potential (GWP). With a GWP of 675, it falls below the EPA’s forthcoming maximum of 700 for most residential and light commercial HVAC applications. This makes it a viable and compliant option for the foreseeable future.
Here is a comparison of the GWP of different refrigerants:
Refrigerant | Global Warming Potential (GWP) |
---|---|
R32 | 675 |
R410A | 2088 |
R22 | 1810 |
The lower GWP of R32 compared to other refrigerants like R410A and R22 means it has a significantly reduced impact on global warming. For more details on how R32 compares to R410A, see our article on r32 vs r410a.
Ozone Depletion Potential of R32
One of the most compelling environmental benefits of R32 is its ozone depletion potential (ODP). R32 has an ODP of 0, making it significantly more environmentally friendly compared to chlorofluorocarbon (CFC) predecessors. Zero ODP means that R32 does not contribute to the thinning of the ozone layer, a vital protection against harmful ultraviolet rays from the sun.
The table below shows the ODP of different refrigerants:
Refrigerant | Ozone Depletion Potential (ODP) |
---|---|
R32 | 0 |
R410A | 0 |
R22 | 0.05 |
R32’s zero ODP makes it an excellent choice for eco-conscious homeowners looking for efficient and sustainable refrigerant options. Additionally, R32 is more efficient than R410A, requiring about 40% less refrigerant in some applications (Super Radiator Coils).
