R32 Refrigerant

7th September 2022

What you need to know about the move to R32 refrigerant…

Why are we moving from R410a and R407c to R32?

This is driven by the latest F-Gas regulations which introduced a phase down programme for high global warming potential (GWP) refrigerants.

What’s the difference between these refrigerants?

R410a has a GWP of 2088 and R407c has a GWP of 1,774. This means if R410a is released to atmosphere it creates 2088 times the global warming effects as CO2. This is in comparison to R32 which has a GWP of 650, allowing it to have less of an impact on the environment.

What is the effect of the phase down to me?

Manufacturers have moved to R32, creating a drop off in production of R410a and R407c. This has then caused the cost of R410a and R407c to rise and its availability to fall. Ultimately this means rising costs and difficulties for the maintenance and repair of your equipment.

Can I “drop in” R32 into a R410a/ R407c system?

No, R32 is not compatible with these systems. You will need to replace the whole system.

Are there any issues I should be aware of with R32?

It is classified as A2L mildly flammable, which is an issue more for our engineers in installation and servicing than for you – we need to guard against the (very low) risk of ignition using slightly different methods and tools. When employing a contractor you need to ensure that their engineers have been properly trained in techniques required for R32, just as all EMS engineers have been.

What are the benefits of R32?

Compared with R410a and R407c, systems with this refrigerant are more efficient as they use less refrigerant per kilowatt of capacity delivered. R32 systems also have a better heating performance at low temperatures and contain less refrigerant. Plus due to the lower GWP, the equivalent CO2 emissions are considerably lower.

High efficiency

The potential refrigerating effect of R32 is 1.5 times that of R410a. The cooling seasonal performance factor (CSPF) of R32 is higher than conventional refrigerants. Its peak power consumption is also lower, helping to alleviate power shortages in large cities during periods of high demand.
