The IEC Working Group 21 has developed additional requirements for flammable (A2L, A2 and A3) refrigerants as part of the IEC 60335-2-40 standard for room air conditioners. The draft document (CDV) has been published and committee members will be voting and provide comments until 30 October 2020.

This vote and the subsequent finalization of the standard can be a milestone towards zero carbon cooling. The uptake of the proposed changes would allow much wider use of the natural refrigerant R290 (propane) in room air conditioners. In view of the dramatic rise in demand for such cooling appliances – an estimated 3.7 billion will be in use by 2050 – , the transition to R290 will significantly reduce their environmental impact.

Zero carbon cooling can only be realized if energy efficiency of cooling appliances is rapidly increased, electricity is 100% renewable, and near-zero-carbon refrigerants are used. There is no question that zero carbon cooling must become a reality by mid-century at the latest in order to meet the international climate targets of the Paris Agreement. For countries implementing their HCFC-phase out and preparing for their HFC phase-down, an updated standard enabling the safe use of climate-friendly refrigerants in air conditioners will enable early action on their commitments under the Montreal Protocol and its Kigali Amendment.

HEAT and Deutsche Umwelthilfe would like to invite you to a one-hour live webinar to exchange information on the current update of the standard, its technical implications and environmental consequences. We are looking forward to your active participation.
