R290 refrigerant: ushers in its highlight moment

For Various Scenarios, Including Both Small Household And Large Commercial Applications.

R290, a natural hydrocarbon refrigerant also known as propane, gained significant traction in 2022, with key advancements driving its adoption. The International Electrotechnical Commission (IEC) expanded the allowable charge limit for R290 in equipment through IEC 60335-2-40 ED7, enabling higher filling amounts (up to 988g) via safety measures like enhanced airtightness. This, coupled with its zero Ozone Depletion Potential (ODP) and near-zero Global Warming Potential (GWP), positioned it as a strong low-carbon alternative amid growing global low-carbon demands.
Major companies advanced R290 applications: Midea launched the world’s first Energy Efficiency Class 1 R290 air conditioner, Emerson developed Copeland scroll compressors for diverse European heat pump needs, and Highly Electric introduced R290-specific compressors. Germany’s 2023 green building subsidies, requiring natural refrigerants in heat pumps, further boosted R290 adoption. Progress also extended to clothes dryers and ice makers, with R290 dominating these sectors, setting the stage for broader growth in 2023 under "dual carbon" goals.
