TRANSCRIPT

As we move into the new decade, do you know that the EU’s policy on Global Warming is to reduce greenhouse gas emissions by 20% in 2020, by 40% in 2030 and by 80% in 2050 based on the low carbon roadmap?

Are you aware that the revised 2014 F-gas regulation aims to cut emissions of F-gases by two-thirds in 2030?

R-32The Future of Refrigerants

Are you aware that in 2025 the EU will ban single split air conditioners with a charge below 3kg running on refrigerants with GWP > 750?

How do we face the future?

The future of refrigerants is here with the R-32 refrigerant, the component in the blend R-410A that accounts for its efficiency and thermodynamic qualities.

What exactly is R-32?

Already used as a component of the blend R-410A

R-410A = 50% R-32 + 50% R-125

Is R-32 really flammable?

R-32 is classified as class 2L refrigerant with low flammability due to a burning velocity of 6cm/s.

Class Alower toxicity

In reality, �ammability of R-32 and other 2L refrigerants is very low.The burning velocity (≤ 10 cm/s) is too slow to cause horizontal flame propagation or explosion.Classification according to ASHRAE34 & ISO817.

Burning velocity of R-32 is very low: 6,7 cm/s (=4m/min or 0.24km/h)

When a flammable concentration of R-32 comes into contact with a flame, it will simply burn away in a

relatively confined fire. It will not explode like propane.

Test with refrigerant leak

How does R-32 compare to other refrigerants in air to air residential heat pumps?

What is the environmental benefit of R-32?

R-32 is the most eco-friendly refrigerant, with up to 75% reduction in environmental impact as compared to

R410A.

R-32 is the future of refrigerants, thanks to its global warming potential (GWP) of 675, one-third lower than R-410A and its zero ozone depletion potential (ODP).
