R32 will be used in Daikin VRV

Daikin says the “mildly flammable” refrigerant R32 will be used in its VRV air conditioning systems in the future.

Speaking at yesterday’s Daikin UK D1 installer conference, new UK md Martin Krutz said that, under the phase-down demands of the F-gas regulations, manufacturers would need to make a choice between either reducing the GWP of refrigerants or limiting the number of units it could produce.

“No manufacturer has an interest to reduce the production amount,” he told the audience of 500 contractors. “Technically there is no reason not to use R32. In short, yes, we expect R32 to be developed for use in larger systems in the future.”

Under the phase-down requirements of the European F-gas regulations, industry will need to find replacements for the higher GWP refrigerants. While R404A, with its GWP of nearly 4,000 is an obvious early target, common refrigerants like R410A and R134a are also under scrutiny …
