While the world’s major manufacturers have been announcing equipment using R32, the Korean manufacturers LG and Samsung have so far remained silent on their plans for adopting the lower GWP refrigerant. However, it appears that LG is now offering its US customers a range of window units using R32 in sizes from 8,000-15,000Btu..
R32, a “mildly flammable” A2L refrigerant, is being promoted as a lower GWP replacement for R410A in smaller air conditioning units. It has already been widely adopted in the Far East and Australasia and is now making inroads into Europe.
R32 was SNAP-listed by the US EPA last year, being approved for use in residential and light commercial air conditioning and heat pumps. Last year, Daikin announced it was to manufacture PTAC units using R32 at its Goodmans plant in Fayetteville, Tennessee.
