primary lower GWP replacement
for R410A in ducted residential and light commercial air conditioners sold in North America.
Which is better R134a or R-410A?
Non-dimensional analysis shows that the inertia of
R410A
is higher than that of R134a, with the following results: (1) at low qualities (churn flow), more liquid R410A reaches the top tubes, so R410A distribution is a little better than R134a; (2) at high qualities (semi-annular flow), more bottom tubes are bypassed by …
What will replace Freon in 2020?
New Freon Regulations in Effect for 2020
For decades, Freon, also known as R-22 and HCFC-22, was the main refrigerant used in residential AC units. However, new AC systems made since 2010 no longer rely on Freon, instead using a refrigerant called
R410A, or Puron
, that has been shown not to harm the ozone.
