A report published at the Proceedings of the National Academy of Sciences (PNAS) has highlighted the emissions that could be avoided by switching to propane as a refrigerant in split-system air conditioners. The research team estimates that such a transition could avoid a 0.09°C increase in global temperature by the end of the century. Global […]
Industry is preparing for a new edition of AS/NZS 60079.10.1:2009, Classification of areas – Explosive gas atmospheres, due to appear later this year. AS/NZS 60079.10.1:2009 is a modified version of the IEC 60079-10-1 standard, published in 2008. Since then there have been two updates to the IEC standard, in 2015 and 2020. The Standards Australia […]
Industry stakeholders have applauded a revised International Electrotechnical Commission (IEC) safety standard that will allow larger charges of flammable refrigerants in household appliances such as air conditioners, heat pumps and dehumidifiers. In particular, it could open the way for greater use of hydrocarbons in residential air conditioning. Standard IEC 60335-2-40 deals with the safety of […]
The votes are set to be counted on an updated international safety standard that would allow increased charge sizes of flammable refrigerants in household air conditioners, heat pumps and dehumidifiers. The proposal has sparked discussion in the world of HVAC&R. Although it would apply to A2, A2L and A3 refrigerants, the proposal has been framed […]
“Cool & Safe: Climate-friendly cooling is just one step away” is a free one-hour webinar on September 30 about the proposed update to the international standard for the use of flammable refrigerants in room air conditioners. It is organised by Environmental Action Germany and independent consulting firm HEAT, in cooperation with German development agency GIZ […]
Charge sizes for flammable refrigerants in HVAC&R equipment are changing with a proposal to raise international limits for room air conditioners, and the adoption of a new standard in Australia for refrigeration appliances. An International Electrotechnical Commission (IEC) working group has released a proposal to update safety standard IEC 60335-2-40. This would allow larger amounts […]
The International Electrotechnical Commission (IEC) has taken the next step towards increasing the charge limit of A3 refrigerants in commercial refrigeration equipment. As reported earlier this year, the change would increase the limit on A3 (flammable) refrigerants such as propane in commercial refrigeration equipment from 150g to 500g. This would enable hydrocarbons to be used […]
