Held under the theme ‘Ammonia and CO2 Refrigeration Technologies’, papers from the 8thInternational Institute of Refrigeration (IIR) Conference are now open to the public. 

The conference, held from 11 to 13 April 2019 in Ohrid, North Macedonia, saw 51 quality papers presented. These papers included 21 on ammonia, with eight focusing on low-charge systems, 22 on CO2 and eight on ammonia or CO2 plus another refrigerant.

Papers included:

  • ‘Ammonia refrigeration: what can we expect in the future?’ by Alexander Pachai from Johnsons Control Denmark.
  • ‘Development of a high efficient NH3/CO2 refrigeration system’ by Kazuhiro Hattori, Ryohei Arimoto and Iwao Terashima.
  • ‘End user perspective on transitioning away from HFC towards natural refrigerants’ by David Schalenbourg from Delhaize Belgium (part of Ahold Delhaize Group).

The conference concentrated on the benefits as well as the need to move towards natural refrigerants and covered topics related to the design and applications of modern ammonia and CO2 systems including heat pump system designs, new innovations, technical and safety guidelines as well as training materials. 180 participants attended from 33 countries to hear five keynote speakers provide insight on the challenges, solutions and perspectives of the field.

Alexander Pachai, president of the IIR Working Group on Refrigeration Safety, led dynamic group discussions on the importance of safety, training and security when handling ammonia and CO2 refrigerants.
