Submit your abstracts to the 3rd IIR Conference on HFO Refrigerants and Low GWP Blends

To be organised by the Chinese Association of Refrigeration (CAR), the call for abstracts for the 2023 IIR Conference on HFOs has now been launched.

Submit your abstract by July 31, 2022!
[Edit September 6: the submission date has been extended until September 20.]

The call for abstracts is now open!


Scheduled to take place on April 4-6, 2023, in Shanghai (China), the 3rd IIR Conference on HFO Refrigerants and Low GWP Blends (HFO 2023) will provide the ideal platform for experts to exchange and discuss the most recent developments in the field.


With HFC phase-down now being implemented across Europe, and likely to be adopted in many other regions, HFO 2023 will offer an opportunity for those developing new working fluids to meet with the equipment design engineers who provide products, and the system installers who use them, as well as with representatives of the end-user community who have to live with the consequences of these scientific and technical decisions.


First held in September 2018 in Birmingham (UK), the IIR HFO conference was welcomed with significant interest and brought together an international audience of over 170 professionals.


Scope of the conference


Papers dealing with any aspect of the following topics from fundamental sciences to applied technologies are solicited. Papers are being sought on the following key topics:

  • Characteristics of HFOs and Low GWP Blends
  • Design issues for systems, components and controls
  • Safety issues
  • Legislation, codes of practice and standards
  • Responsible use and environmental considerations.
