On April 16-18, The International Institute of Refrigeration (IIR) will host its biannual International Conference on Ammonia and CO2 Refrigeration Technologies in Ohrid, Republic of Macedonia. The previous five offerings were great successes and it is hoped that this year will continue the trend of instilling confidence and dispersing information on these highly-efficient, natural refrigerants.

Ohrid and its famous lake will once more be host to three days of in-depth discussions on the place of ammonia and R744 in the HVAC&R sector and the barriers that still remain to mass-adoption. The perspective of the conference will be truly global with speakers from Europe, North America, Asia and Africa.

The 6th IIR conference will look at how to further improve the safety of both ammonia and carbon dioxide systems as well as offering a platform for the introduction of new innovative components for both systems including; high-pressure ammonia and R744 compressors and “shell & plate” heat exchangers.

Ammonia going from strength to strength; CO2 gaining ground

Andy Pearson, of Star Refrigeration Ltd, will deliver a keynote speech on why ammonia is such a good refrigerant, a change from the 5th IIR Conference where Andy Pearson spoke of the need for safety to be improved in the usage of ammonia. Alongside the focus on NH3, CO2 will also be a hot topic, with Dr Armin Hafner, Norway, SINTEF Energi AS presenting on "2020 Perspectives for CO2 refrigeration and heat pump systems" and Dr Predrag Hrnjak, University of Illinois spekaing on "In-tube evaporation of CO2: visualisation and effect of oil".

The preliminary programme features the following presentations:

  • Global trends, design and safety requirements for ammonia installation, Niels Vestergaard, Danfoss
  • Parallel operation of NH3 screw compressors - The optimum way, Bas Pijnenburg and John Ritmann, Bitzer
  • Piston versus screw compressors – a life cycle analysis of high pressure ammonia systems, Kenneth Hoffmann and Vaclav Ruzek, GEA Refrigeration
  • New proposals for ventilation rates in machine rooms and a case study of a large cold store in Belgrade, Serbia, Alexander Pachai, Johnson Controls
  • Ammonia and CO2 applications in industrial refrigerant plants, Jan Boone and Ivaylo Ivanov, Mayekawa

In addition to these presentations, there are several academics who will also be speaking on both ammonia, R744 and absorption refrigeration.

About the 6th IIR Conference

This is the 6th IIR conference, which occurs bi-annually in the south-western Macedonian city of Ohrid. The conference combines presentations from companies, academics and Professors to create a unique sphere for new and old technologies to be assessed and bettered. The conference also includes a sightseeing tour of the old town of Ohrid or an excursion to the “Sv. Naum” complex.
