R22 vs R410A | Why It Matters

refrigerant-bottlesR-22 is an alkyl halide refrigerant. Alkyl halide refrigerants contain bromine or chlorine. This makes R-22 an ozone depleting refrigerant. However, R-410A only contains fluorine, which makes it a non-ozone depleting refrigerant.

R-410A refrigerants operate at a higher efficiency than R-22. Power plant greenhouse gas emission is much less due to the use of R-410A, therefore, the overall global warming impact of R-410A is substantially lower compared to R-22.

In 2010, manufacturing of R-22 equipment was discontinued for use in air conditioning and refrigeration systems. R-22 is a hydro-chloroflourocarbon (HCFC), which results in its ozone depletion.

R-410A has the following important characteristics, which put it at the top of the list for new refrigerant system installations:

  • R-410A is a hydrofluorocarbon (HFC) refrigerant.
  • R-410A is azeotropic mixture of HFC-32 and HFC-125.
  • R-410A is around 1.7 times the pressure of R-22
  • R-410A carries a higher caloric heat load than R-22, and is denser
  • R-410A uses POE (polyester oil), which absorbs moisture rapidly. It is imperative to keep moisture from reaching the oil.

We need to do all that we can to make sure we are using environmentally friendly chemicals. The studies have been conducted and there is proof that R-410a is the future of cooling.  R-22 allocation is going down.  In March 2014, the EPA announced their 2012-2014 findings. R-22 allocations is scheduled to be aggressively reduced by 2016. Let us help you make the transition.
