15th IIR-Gustav Lorentzen Conference on Natural Refrigerants

Registration open!


With the increasing need for global warming countermeasures, natural working fluids have become a clear vector to reducing the CO2 footprint of the refrigeration, and heating and cooling sectors and migrating towards long-term sustainable solutions.


Scheduled to take place in Trondheim (Norway) on June 13-15, 2022, the 15th IIR-Gustav Lorentzen Conference on Natural Refrigerants (GL 2022) will provide the ideal platform for discussion on the latest research results and advances related to the use of natural working fluids in different types of systems and application areas.


The call for abstracts closed September 15, 2021.


Register today!
