Spotlight on Commission B2: at the forefront of refrigerating equipment



“All the activities described … are the result of collaboration by all commission members and the IIR staff …” Prof. Dr.-Ing. Michael Kauffeld



Coordinated by the IIR Science and Technology Council, Commission B2 focuses on promoting knowledge of refrigerating equipment technologies and their applications worldwide. A key Commission for most IIR activities, B2 regularly coordinates and pools skills with other IIR commissions to promote and share research findings. Comprised of 70 experts from 25 IIR member countries worldwide, B2 is a truly global endeavour.

Phase Change Materials (PCM) and Slurries for Refrigeration and Air Conditioning IIR Conference



Hosted by Karlsruhe University of Applied Sciences, the next PCM and Slurry Conference is set to take place on 18 to 20 May 2016 in Karlsruhe, Germany.



Building on the success of the previous events in the series held in Karlsruhe, Germany (2009), Sofia, Bulgaria (2010) and Kobe, Japan (2012), the 11th IIR Conference on PCM and Slurries for Refrigeration and Air Conditioning, with the collaboration of Commissions B1, B2 and D1 is designed to provide an open international forum where academics and stakeholders from across Europe and worldwide will showcase and exchange the latest research findings, developments and trends in the field.



PCMs and slurries enhance not only the performance of air-conditioning and energy saving systems but also mechanical and chemical processes in industrial applications, and have become key technologies that attract many researchers.



The event will give scientists and practitioners an opportunity to meet their peers and share ideas that will shape PCM research and engineering for years to come.



The thematic scope of this conference encompasses key topics such as:


  • Thermophysical and rheological properties of phase-change materials and slurries
  • Transport phenomena and time-dependent behaviour of PCM and slurries heat, mass and momentum transfer
  • Novel and optimised PCM and slurries for refrigeration and air conditioning applications
  • Innovative and improved equipment and logistics for generation, handling, distribution and employment of PCM and slurries
  • Renewable heating and cooling by using PCM and slurries
  • Thermal energy storage and energy savings via PCM and slurries
  • Industrial and building applications of PCM and slurries
  • Sustainability impact of refrigeration and air conditioning technologies involving PCM and slurries.



As always, the conference aims to highlight novel PCM and slurries technologies and applications.



Ever-active Commission B2


Since the last IIR International Congress of Refrigeration (ICR) in August 2011 Commission B2 has participated in 9 IIR conferences and 12 IIR co-sponsored conferences.



The successful 11th IIR-Gustav Lorentzen Conference on Natural Refrigerants which took place in Hangzhou, China, in 2014 attracted 135 papers (available in FRIDOC), attesting to the sturdiness of research in natural refrigerants, especially CO2 and hydrocarbons, which were presented during 24 sessions.



The conference covered hot topics such as CO2 systems and heat pumps, heat transfer and heat exchangers, hydrocarbons such as R290, commercial and supermarket refrigeration, air and water, refrigerant charge reduction, ejectors, emissions reduction and energy savings and safety issues.



During a joint meeting with Commissions B1-B2-E1-E2 held at the event, commission members were able to review ongoing projects.



The Commission was also involved in the 6th Ammonia and CO2 Refrigeration Technologies Conference which took place in Ohrid, Macedonia in April 2015.



Commission B2 will naturally be present at the 24th IIR International Congress of Refrigeration (ICR) on August 16 to 22, 2015 in Yokohama, Japan.

Technical texts



Determined to lead advances in refrigerating equipment, Commission B2 is currently involved in the preparation of two IIR technical guides on CO2 (English version) and on ammonia (French version).



Commission B2 members also participated in several special issues of the International Journal of Refrigeration, including recent ones on solar cooling and magnetic refrigeration.



With the collaboration and expertise of Commission B2 on two IIR Informatory Notes, one on the EU F-Gas Regulation and other regulations restricting HFC use.



These publications are valuable tools that assist various refrigeration industry stakeholders in strategic actions to take in anticipation of and following regulatory changes concerning refrigerants.



Commission B2: Working Groups



An important commission in many other commission activities, Commission B2 is also actively involved in 6 IIR Working Groups:


  • Magnetic Cooling
  • Mitigation of Direct Emissions of Greenhouse Gases in Refrigeration
  • Phase-Change Materials and Slurries for Refrigeration and Air Conditioning
  • Refrigerant-Charge Reduction in Refrigerating Systems
  • Refrigerant-System Safety
  • LCCP Evaluation.


In addition to organizing numerous conferences and workshops, these Working Groups remain very active and have participated in the publication of three Informatory Notes:


  1. Magnetic Refrigeration at Room Temperature
  2. Containment of Refrigerants within Refrigeration, Air-Conditioning and Heat-Pump Systems
  3. Refrigerant-Charge Reduction in Refrigerating Systems

About IIR Working Groups


IIR Working Groups operate on a temporary basis to bring together specialists in order to work on projects arising from current issues. Their aim is to promote development, provide knowledge and give recommendations in these spheres



In order to achieve these objectives, they hold conferences and workshops, write publications and provide recommendations. Members of working groups are IIR members from industry, academia and research-centre settings or are refrigeration practitioners.
