Reason 1

Up to 12% more efficient.

Test data in Daikin's labs of inverter-driven compressors for rooftop units and water-cooled chillers found that full-load and partial-load efficiency rating metrics can be improved by up to 12% using R-32 instead of R-410A.

reason 2

Light weight units.

R-32 refrigerant's efficiency and capacity can allow for light weight units in certain applications.

Return to Home

Reason 2

Light weight units.

R-32’s excellent thermodynamic properties allow the HVAC system to use less refrigerant to accomplish the same heat transfer compared to blends for any efficiency level. Moving less refrigerant through the HVAC systems allows for design with smaller motors, smaller diameter piping and smaller heat exchangers to provide the same capacity and efficiency as blended refrigerants, resulting in lighter weight and more compact units.
Better for
the planet.

reason 3

Better for the planet.

R-32 refrigerant has a significantly lower total life cycle refrigerant impact on the environment compared to R-410A.
Learn More
Return to Home

Reason 3

Better for the planet.

Total life cycle refrigerant impact measures the direct emissions from refrigerant, as well as the indirect emissions from electricity consumption. Because R-32 has a GWP of 675 and requires less charge in certain systems, direct emissions from those systems can be up to 80% lower than similar R-410A systems. And because R-32 can obtain higher efficiencies than many blends, units can be designed to consume less electricity over the lifetime of the equipment. The result? Fewer carbon emissions that contribute to climate change.

Reason 4

Easy to work with.

As a pure, single-component refrigerant, R-32 can be topped off and recharged in the field, in both liquid and gas phases, without changes in composition. It is easy to clean and reuse on-site, and is easy to reclaim and recycle off-site  with a simple cleaning process, particularly as compared to blends with HFOs that are typically reclaimed by being distilled to their pure compounds and then remixed.

R-32 systems can have a positive impact on climate change. Total life cycle refrigerant impact measures the direct emissions from refrigerant, as well as the indirect emissions from electricity consumption. Because R-32 has a GWP of 675 and requires less charge in certain systems, direct emissions from those systems can be up to 80% lower than similar R-410A systems. And because R-32 can obtain higher efficiencies than many blends, systems that consume less electricity over those systems’ lifetimes can be introduced. The result? Fewer carbon emissions that contribute to climate change.

Reason 14

Efficient in harsh conditions.

R-32 systems can be more efficient in a broader range of operating conditions in certain applications. Testing in Daikin’s labs of inverter-driven compressors for rooftops units and water-cooled chillers found that full-load and partial-load efficiency rating metrics can be improved by up to 12% by using R-32 instead of R-410A. Daikin estimates over 100 million R-32 units are in operation around the globe in more than 90 countries and climates, including Japan, India, Australia, the Middle-East, Russia, Greenland, the European Union and the United States.

15
reason 15

10% more thermal capacity.

R-32 refrigerant has excellent thermodynamic performance, with about 10% more thermal capacity than R-410A.
Learn More
Return to Home

Reason 15

10% more thermal capacity.

R-32 has greater latent heat capacity than R-410A, which means that R-32 can achieve the same capacity at a lower refrigerant flow rate. And at a lower flow rate, less energy is required to produce refrigerant flow, resulting in higher efficiencies for R-32. 
No glide.
16
reason 16

No glide.

R-32 refrigerant has no negative performance impacts due to composition change, regardless of the type of heat exchanger.
Learn More
Return to Home

Reason 16

No glide.

R-32 is a single component refrigerant and has no glide. When blends separate, you can negatively impact heat exchanger and system performance. Because R-32 is a single component refrigerant, its composition doesn’t change, so there are no negative blend-related performance impacts in any type of heat exchanger.

Reason 17

Design for low total cost of ownership.

When you combine the low cost for R-32 per pound and the low charge quantity with low electricity consumption, R-32 can yield low total cost of ownership. Add in easier handling from recharging in the field as compared to non-azeotopic blends, R-32 can add up impressive savings.
Tops off.
18
reason 18

Tops off.

R-32 is a pure, single component refrigerant that doesn’t change composition over time.
Learn More
Return to Home

Reason 18

Tops off.

Because R-32 is a pure, single component refrigerant, service technicians can be assured that the composition has not changed over time, so it is easy to top off during a service call. With non-azeotropic blends, it is generally not recommended to top off; the system may need to be evacuated and then recharged with new refrigerant, which can be costly in terms of materials and labor.

Reason 23

Lower charge.

Because R-32 is a pure, single component refrigerant with excellent thermodynamic performance characteristics, an R-32 system could have up to 40% less charge than a similar R-410A system, meaning you could reduce the amount of refrigerant in the system and potentially also reduce the amount of refrigerant leaking to the environment.

While there is no single international standard for GWP limits, many countries have set a benchmark of less than 750. For example, by 2025, the European Union's F-gas Regulation will ban certain new split AC systems containing less than 3kg of HFCs that have a GWP greater than 750; Canada will limit GWP for refrigerants used in certain new comfort chillers to 750 by 2025; and Japan has targeted a GWP of 750 for various room air conditioning and commercial air conditioning.

Return to Home

Reason 27

Zero composition change.

Because R-32 is a single component refrigerant, its composition doesn’t change over time as it does with most blended refrigerants. This means there are no negative performance impacts due to composition change. And R-32 can be easily topped off or recharged in the field in either a liquid or gas phase.

Reason 28

Easy to reuse and recycle.

Pure, single component R-32 makes “Reduce, Reuse, Recycle" a new reality in the industry.
  • Reduce: Certain R-32 systems could have up to 40% less charge than similar R410A systems.
  • Reuse: R-32 can be topped up and recharged in the field, in both liquid and gas phases, without changes in composition. It is easy to clean and reuse on-site. Section 608 of the Clean Air Act allows appliance owners to reuse recovered refrigerant in other equipment under same ownership. A single component refrigerant can’t lose its composition like many blended refrigerants and will retain its quality over time.
  • Recycle: R-32 can be reclaimed and recycled off-site with a simple cleaning process, as compared to blends with HFOs that are typically reclaimed by being distilled to their base components and then remixed.
