Symposium 2023

From 26 to 30 June 2023 the industry event provides important information on current developments and applications with natural refrigerants. The digital format of previous years has proven itself and was well received by participants. This is why this year’s eurammon symposium for natural refrigerants is held online again.

Here the online lecture event addresses solutions for heating and cooling applications, and presents case studies accordingly. "Interest in the use of natural refrigerants is growing across an ever increasing range of applications. This year’s eurammon Symposium addresses this interest from current regulatory and technological developments to applications and case studies," says Ákos Murin, chairman of the Steering Committee of eurammon e.V.

 A week full of insights

Three keynotes on the first day will set the scene for the further course of the symposium. One will present a project currently underway to investigate energy use and greenhouse gas emissions from the transport, industrial and commercial refrigeration sectors in the UK. A second lecture will deal with the evolution of CO2 refrigeration technology during the last two decades. A further keynote will be about an initiative for natural refrigeration engineering in the Middle East. The subject of the second day will be EU policy and several other regulations updates. During the remaining days of the symposium the focus will be on new technologies and applications that are supporting the industry in the transition to a sustainable future with natural refrigeration engineering applications.

 "With the online symposium, we are reaching out to a global audience interested in natural refrigerants," says Murin. "The symposium is a chance to learn, ask questions, and share knowledge. We look forward to many participants joining us from 26 to 30 June."
