The International Institute for Applied Systems Analysis modeled emissions of different refrigerants in split ACs.
U.S. companies should proactively push to remove barriers for R290 in air conditioning and heat pumps says EIA’s Avipsa Mahapatra.
Thus, there is no need to alter plans for an aggressive phase down of HFCs, the study says.
ATMO America: EPA Collects Feedback From Conference Attendees On The AIM Act Technology Transitions Rule
Under the AIM Act, the EPA is allowed to shape a HFC phase down, manage the technology transition and support the proper management of refrigerants across the sectors using these chemicals.
The study notes the difficulty of removing TFA from drinking water and the potential for health effects.
Countries need to reduce HFCs production and consumption faster and at greater rates to allow for an emissions scenario compatible with the Paris Agreement.
As much as 988g of R290 can be used in split AC systems with certain enhancements, according to new IEC 60335-2-40 standard.
EU-based producers reported a 25% average increase in the price of high-GWP refrigerants like R404a, R410a and R134a.
Ban on certain stationary split air-conditioning and split heat pump equipment containing f-gases would help adoption of R290 equipment.
NGOs don’t think it goes far enough in rolling back HFCs, while trade groups fear it is too ambitious and will impair heat pump deployment
