UPDATED: Updates on ammonia technology from the 2011 IIR Congress

Prague is hosting the 23rd IIR International Congress of Refrigeration (ICR) on 21-26 August 2011 to present updates on research and commercial viability of refrigeration systems. ammonia21.com reports live from the event. UPDATE: Papers now available to download from IIR website

Researchers, engineers, government officials and end-users are meeting this week at the IIR ICR in Prague to share latest progress in research and commercialisation of refrigeration equipment using ammonia, hydrocarbons, CO₂ and synthetic working fluids in refrigeration and beyond. Thematic paper sessions, workshops and plenary lectures pair with the exhibition organised in the Prague Congress Centre's foyer.
