Did you know it’s likely you’re already using R-32 refrigerant? For many years, R-32
has been a key component of many other blended refrigerants. Because of R-32’s
availability, low cost, and excellent performance, it is used as a key ingredient in
blends, including R-410A. In fact, R-32 is the pure, single component refrigerant that
helps make blends like R-410A so efficient.
Because of R-32’s excellent thermodynamic performance characteristics, an R-32
system could have up to 40% less charge than R-410A in certain applications,
meaning you could reduce refrigerant usage in the equipment and potentially also
reduce quantities leaking to the environment. R-32 can help us achieve the 3Rs:
Reduce, Reuse, Recycle, a new reality in the industry.
Being a pure, single-component refrigerant, R-32 can’t lose its composition like a
blended refrigerant and is well suited to retain its quality over time. It can be topped
off and recharged in the field in both liquid and gas phases; because the
composition doesn’t change, it’s easy to clean and reuse on site. R-32 can be
reclaimed and recycled with a simple cleaning process, as compared to blends with
less stable HFOs that must be distilled to their pure compounds and then remixed.
What’s not new, though, is the adoption of R-32 across the world. Back in 2012, HVAC
companies in Japan introduced R-32 in split systems, followed by VRF systems and
chillers. Companies in other countries across Europe, as well as India, Thailand and
Australia followed suit in 2014. In 2016, window air conditioners in the United States
began to take advantage of R-32’s many benefits. With more than 100 million R-32
units already in operation worldwide and more than 20 million coming on line every
year, R-32 has become the de facto global standard.
