Trainer Ben Bartle-Ross takes a moment to review the key things you need to understand about R32
The industry is abuzz with news about R32 at the moment, with several major manufacturers launching RAC and PAC models – and the price of R410A focusing real attention on the value of switching to models using the new refrigerant.
I therefore thought it worthwhile taking a moment to look at the key things air conditioning engineers need to understand about R32.
Forgive me if you know all about this already but it is such an important issue that I think it is worth looking at the key issues behind this change. This is all about reducing the impact of air conditioning on the environment, and particularly the global warming potential (GWP) of the refrigerants involved.
Why the change and why now?
These changes have come about as part of the F-Gas Regulations which are a key element of a legislative drive seeking to reduce the harm that hydrofluorocarbons (HFC) refrigerants have on global warming.
As part of F-Gas, CO2 is used as the base mark with a global warming potential (GWP) of 1.
R410A has a GWP of 2,088 compared with R32 which has a GWP of 675. R32 is already a familiar refrigerant to the industry as it makes up 50% of R410A.
R32 systems also uses up to 20% less refrigerant than R410A ones, making it more efficient which also means lower carbon emissions and lower energy costs. Made up of a single component, it is easy to recycle and has zero-ozone depleting potential.
