9th IIR Conference on Ammonia and CO2 Refrigeration Technologies

An online conference


2 days: 5 keynotes + 29 presentations


Bridging the gap between industry and academia, the 9th IIR Conference on Ammonia and CO2 Refrigeration Technologies will focus on the intensifying global trend towards using natural refrigerants, such as ammonia, carbon dioxide and hydrocarbons, in various refrigeration applications worldwide.


This conference will address the design of modern ammonia and new CO2 systems and technological innovations, improving energy efficiency as well as technical guidelines, environmentally friendly technologies and safety regulations.


Of those that exist today, ammonia and CO2 are two of the oldest refrigerants, with evidence of their use since the 19th century, and their unique technical properties has assured their continued exploitation centuries on.


Registered delegates will have access to the recorded sessions for up to 10 days after the conference!
