Scientists back hydrocarbon heat pumps
As the debate over the revisions to the F-gas regulation rumbles on, a group of more than 40 scientists from 24 different universities and research institutes in Europe have signed a position paper supporting the use of hydrocarbons as refrigerants in heat pumps. The researchers argue that hydrocarbons such as propane and isobutane are just […]

Propane AC could help avoid global temperature rises
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 […]

Vote imminent on flammable standard
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 […]

EIA calls for ban of HFCs in split systems
The Environmental Investigation Agency (EIA) has renewed its call for hydrofluorocarbons (HFCs) to be banned in domestic air conditioners, with the claim that a switch to hydrocarbons could prevent harmful emissions equal to 1,400 coal-fired power stations running for a year. New research commissioned by the EIA found that making the change could avoid 5.6 […]

Thailand runs R290 safety test for AC units
The Thailand Refrigeration and Air Conditioning Nationally Appropriate Mitigation Action (RAC NAMA) has conducted Thailand’s first live safety testing of R290 (propane) for AC units. The results, which support the safety of the flammable refrigerant, have been submitted to the Thai government to assist in its review of the country’s building code, says the organisation. […]

Flammable future for split systems?
German development agency GIZ has published a resource guide promoting the use of R290 (propane) in split system air conditioners. The guide highlights the efficiency benefits and potential emissions reductions that propane offers, and addresses concerns about flammable refrigerants. Ultimately, it aims to encourage policy-makers to facilitate the market uptake of energy-efficient split systems using […]

IEC rejects rise in flammable charge limit
The International Electrotechnical Commission (IEC) committee responsible for IEC Standard 60335-2-89 has narrowly voted down a draft international standard that would have raised the allowable charge of flammable refrigerants in certain appliances. The vote comes after a five-year effort to raise the charge limit of flammable refrigerants such as propane and isobutane in some commercial […]

Charge limit increase imminent
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 […]
