Commissions and sub-commissions of the IIR
IIR Sections and Commissions
The 10 IIR Commissions specialise in the main refrigeration domains. They take part in the dissemination and the enhancement of scientific and technical knowledge in their domains by various means:
- organise or sponsor international conferences
- create and conduct working groups
- publish books or Informatory Notes.
These activities are coordinated by the Science and Technology Council (STC). In addition, the STC is responsible for appointing the members that make up each Commission as proposed by the Commission presidents.
The Commissions are divided into 5 sections:
Section A - Cryogenics and liquefied gases
Section A focuses on refrigeration science and technology at low temperatures: the cryogenic domain covers 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 liquefied natural gas (LNG).
Commission A1 - Cryophysics & cryoengineering
Subjects: research, development and industrial activities at the lowest temperatures
Commission A2 - Liquefaction & separation of gases
Subjects: liquefied gas industry, including air separation and LNG technology
Section B - Thermodynamics, equipment and systems
Section B focuses on the technological and scientific fundamentals of traditional refrigeration, excluding cryogenic temperatures. Section B is a key player in most of the IIR conferences. A number of Working Groups are organised within the scope of Section B.
Section C - Biology and food technology
The activities of Section C deal with the application of refrigeration technologies in life and food sciences.
Commission C1 - Cryobiology, cryomedicine & health products
Subjects: application of refrigeration technologies in various branches of medicine
Commission C2 - Food science & engineering
Subjects: application of refrigeration technologies in the area of food science, and modelling the transfer of heat and matter during refrigeration processes.
Section D - Storage and transport
Section D is involved in the temperature-controlled logistics and distribution of temperature-sensitive products, from foodstuffs to health products, from artwork to chemicals. It thus covers the issues of storage, transportation by land, air or water, packaging, distribution and delivery to the consumer, and the traceability of the cold chain.
Section E - Air conditioning, heat pumps and energy recovery
Section E focuses both on air conditioning and heat pumps. Air conditioning is a subject that is now more frequently addressed due to the need for both better indoor comfort in an increasing number of countries and the effects of global warming. Also providing a cooling effect, heat pumps are expected to be the most common solution in the future for all year round operations due to their high energy efficiency.
Commission E1 - Air conditioning
Subjects: various aspects of air conditioning from equipment to systems.
Commission E2 - Heat pumps & energy recovery
Subjects: promotion of the scientific and technological knowledge of heat pump and energy recovery fields.
Presidents of Commissions may establish temporary Sub-Commissions in order to study certain aspects within the domain of the Commission.
