IIR Sections & Commissions

The activities of the IIR's 10 commissions  are grouped in 5 sections which are coordinated by the Science and Technology Council.Commission members come from industry, university, and research-centre specialists or refrigeration practitioners.

 

The aim of a commission is to promote and enhance scientific and technological knowledge in its respective fields thanks to the following activities: organization or co-sponsoring of international conferences and publication of books and Informatory Notes.

 

Commission members are proposed by member countries then appointed by the Science and Technology Council following proposals from Presidents of Commissions.

 

Section A: Cryogenics and liquefied gases

President of Section A: Dr Ralf Herzog (Germany) See biography


Section A Cryogenics and Liquefied Gases focuses on refrigeration science and technology at low temperatures: the cryogenic domain spans the lower part of the temperature scale, from absolute zero to 120 K, thus encompassing the normal boiling points of air gases as well as of liquid natural gas (LNG).
Section A comprises two Commissions, A1 Cryophysics and Cryoengineering, and A2 Liquefaction and Separation of Gases. Commission A1 deals with research, development and industrial activities at the lowest temperatures, including low-temperature physics, applications of superconductivity and helium cryogenics. Commission A2 essentially covers the liquefied gas industry, including air separation and LNG technology, two mature domains with high economic stakes and ongoing developments addressing important societal issues such as energy efficiency and carbon sequestration.
Section A also maintains and develops relations with other Sections of the IIR, mainly Commission B1 Thermodynamics and Transfer Processes in the field of thermodynamics and transfer processes, essential tools of the cryogenic engineer, and Commission C1 Cryobiology, Cryomedicine and Health Products for the cooling of biological specimens and living tissues for preservation or treatment which require implementing cryogenic processes. Section A consists of a panel of multidisciplinary professionals and experts in sciences and technologies such as thermodynamics, condensed matter physics, materials science, heat transfer, fluid dynamics, vacuum and leak-tightness, instrumentation and process control, applied to the low-temperature domain.

 

 

Section B: Thermodynamics, equipment and systems

President of Section B: Prof. YongTae Kang (South Korea) See biography


Section B Thermodynamics, Equipment and Systems of the IIR focuses on the technological and scientific fundamentals of classical refrigeration, excluding cryogenic temperatures. The fundamentals are represented by its Commission B1 Thermodynamics and Transfer Processes whereas Commission B2 Refrigerating Equipment covers all kinds of refrigeration technology. Section B is a key player in most of the IIR international conferences; except for the International Conference of Refrigeration (ICR) organised every 4 years for all 10 IIR Commissions, where approximately 50% of all presentations are related to Section B topics.
Independently, and together with other Sections, Section B hosts a multitude of conferences such as the Gustav Lorentzen Conference on Natural Working Fluids, the Ohrid Conference on Ammonia and CO2 Refrigeration Technologies, the Jordanian Conference on Refrigeration and Air Conditioning; or conferences on Thermodynamic Properties and Transfer Processes of Refrigerants, on Magnetic Refrigeration at Room Temperature, on Compressors and Coolants, and on Phase Change Materials and Slurries for Refrigeration and Air Conditioning.
A number of Working Groups, where emerging topics in refrigeration are discussed by IIR experts with the aim of publishing results in handbooks or other forms publications, are organised within the scope of Section B. Main topics include mitigation of direct emissions of greenhouse gases in refrigeration, refrigerant charge reduction in refrigerating systems, magnetic cooling, life cycle climate performance evaluation, and refrigerant system safety.
Section B is comprised of more than 120 members from across the globe.

 

 

Section C: Biology and Food technology

President of Section C: Mr Jacques Guilpart (France) See biography

 

The activities of Section C deal with the application of refrigeration technologies on life sciences and food sciences.
Commission C1 Cryobiology, cryomedicine and health products is particularly focused on the application of refrigeration technologies on various branches of medicine: cryosurgery and oncology, cryotherapy, blood, organs and tissue preservation, health products (especially vaccines and thermosensitive preparations). On the one hand, the work focusses on the biological and biochemical aspects of the effects of refrigeration on organs, tissues and treated products, and on the other hand on the applied refrigeration techniques and technologies.
Commission C2 food science and engineering is focused more particularly on the application of refrigeration technologies in the area of food sciences: preservation (refrigeration, freezing); hygiene and safety in its microbiological aspect; process (lyophilisation, cryoconcentration, cryoprecipitation, partial or total crystallisation). The work focuses on establishing a model for the transfer of heat and matter during refrigeration treatments, on the effects of refrigeration on food products, and on the evolution kinetics of products kept in cold storage. The work deals with the impact of the integrity of the cold chain on the quality of food, including in warm climate countries.

 

 

Section D: Storage and transport

President of Section D: Mr Gérald Cavalier (France) See biography

 

Section D Storage and Transport of the IIR is involved in the controlled-temperature logistics and distribution of temperature-sensitive products, from foodstuffs to health products (medicines, vaccines, blood products, organs ...) from artwork to chemicals.
It addresses all issues of equipment and solutions for a durable cold chain from the production or manufacture, to the consumption or use of these products.
Section D thus covers the issues of storage, transportation by land, air or water, packaging, distribution and delivery of these products to the consumer, and the traceability of the cold chain.
The Section is involved in warehouse and platform equipment, devices for temperature-controlled transport, coolants or cool packs, small coolers and refrigerated containers, chillers, refrigerated furnishings, refrigerated cabinets, climate chambers, refrigerators and freezers, but also to thermometers and temperature recorders.
The cold chain involves many temperature ranges, both positive and negative, from -80°C to + 63°C.


 

Section E: Air conditioning, heat pumps, energy recovery

President of Section E: Prof. Renato Lazzarin (Italy) See biography

 

IIR Section E co-ordinates the work of the both Commissions E1 Air-Conditioning and E2 Heat Pumps and Heat Recovery.
The cores activities and interests of both Commissions are strongly connected resulting in tight collaborate and jointly organised conferences.
Air-conditioning is a subject that is now more frequently addressed due to both better comfort in an increasing number of countries and the effects of global warming. Now, even countries where demand for air-conditioning during summer months was limited, due to a cooler climate, require the operation of an air-conditioning plant for longer periods. The demand of heating is nevertheless significant and the most efficient system to provide heating is undoubtedly the heat pump. No other technology can provide net primary energy savings, economic benefits to users and reduced cli¬mate impact at the same time.
Also providing a cooling effect, the heat pump is expected to be the most common solution in the future for all year round operations. The combination of these technologies, with heat recovery capable buildings or industrial plants, cooling and heating requirements can be meet in the most efficient, reliable, cost effective and environmentally friendly way.
Section E with its Commissions is made up of 101 experts.
