⭐ Core Definition: International Institute of Refrigeration

The International Institute of Refrigeration (IIR) (also known, in French, as the Institut International du Froid (IIF)), is an independent intergovernmental science and technology-based organization that promotes knowledge of refrigeration and associated technologies and applications on a global scale that improve quality of life in a cost-effective and environmentally sustainable manner, including:

  • Food quality and safety from farm to consumer
  • Comfort in homes and commercial buildings
  • Health products and services
  • Low temperature technology and liquefied gas technology
  • Energy efficiency
  • Use of non-ozone-depleting and low global warming refrigerants in a safe manner.

Its scientific and technical activities are coordinated by ten commissions which are divided into five distinct sections.

International Institute of Refrigeration in the context of Cryogenic

In physics, cryogenics is the production and behaviour of materials at very low temperatures.

The 13th International Institute of Refrigeration's (IIR) International Congress of Refrigeration (held in Washington, DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (−153 °C) to distinguish these terms from conventional refrigeration. This is a logical dividing line, since the normal boiling points of the so-called permanent gases (such as helium, hydrogen, neon, nitrogen, oxygen, and normal air) lie below 120 K, while the Freon refrigerants, hydrocarbons, and other common refrigerants have boiling points above 120 K.
