Genetron AZ-20 is the original brand of R-410A refrigerant, invented by
Honeywell as the primary global solution to replace ozone-depleting
refrigerants in residential and commercial unitary air conditioners. R-410A is
an azeotropic mixture of HFC-32 and HFC-125, with near-zero glide allowing for
both predictable performance and easy handling and recycling. Millions of
R-410A air conditioners have been sold around the world, and over 25 equipment
manufacturers now offer an R-410A option in their product line.
R-410A has a significantly higher capacity and moderately higher operating
pressure than R-22, making it a cost-effective replacement for R-22 in
higher-efficiency air conditioning and heat pump systems. In new unitary
systems optimized for R-410A use with either scroll or reciprocating
compressors, R-410A has been shown in tests to have a 5-to-6 percent higher
Energy Efficiency Rating (EER) than R-22. The higher capacity also enables the
design of smaller, more compact air-conditioning equipment.
Because it behaves like an azeotrope, R-410A is easy to service in the
field. It won't meaningfully change composition if an air conditioner suffers a
refrigerant leak, and R-410A can be easily recovered and reclaimed, giving it a
substantial advantage over other R-22 replacements such as R-407C or R-417A.
R-410A has been given an A1 safety classification by ASHRAE.
R-410A is not designed for use as a retrofit refrigerant for R-22. Working
with R-410A requires that you use tools, pumps, and recovery equipment and
tanks rated for the higher pressure.
Genetron AZ-20 refrigerant is available in a variety of package sizes.
Equipment manufacturers who require help in converting their products from R-22
to R-410A should contact us to take advantage of our global experience in
helping OEMs to optimize systems for this high-performance refrigerant.
