23rd IIR International Congress of Refrigeration with R744.com booth

Bringing together expertise from nearly all refrigeration fields, the 23^rd International Institute of Refrigeration (IIR) International Congress of Refrigeration (ICR) will take place in Prague, Czech Republic 21-26 August 2011. Held every 4 years, the Congress will showcase the latest developments and progress in refrigeration equipment, including carbon dioxide applications. R744.com will reporting from the event and will have a booth at the ICR exhibition.

A seminal event, the 23^rd International Congress of Refrigeration will include thematic paper sessions, workshops, and short courses and will include a 5-day exhibition in the Prague Congress Centre hall foyer and technical visits. R744.com will be attending the event, with a booth on the first floor of the Congress Centre.

Aimed at both industrial and academic stakeholders, the 23^rd IIR Congress will feature:

5 plenary sessions with distinguished speakers
Around 120 keynote presentations
600 Regular and short oral presentations with optional posters
10 IIR Commission meetings
Exhibition of state-of-the-art technologies and laboratory equipment
Side events – workshops
Welcome party, concert of Baroque music, gala dinner with awards ceremony

About the IIR

The International Institute of Refrigeration, which celebrated its centenary in 2008, is an independent intergovernmental organisation with 60 member countries, nearly 500 experts and 600 corporate and private members. The organisation promotes knowledge of refrigeration and associated technologies.

Previous IIR International Congresses of Refrigeration have been held in Beijing, Washington DC and Sydney.
