IIR   Coulomb - the refrigerants future IIR Coulomb - the refrigerants future Presentation Transcript

  • www.iifiir.org The IIR
  • www.iifiir.org • 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 The International Institute of Refrigeration (IIR), an independent intergovernmental science and technology based organization, promotes refrigeration knowledge and associated technologies that improve quality of life in a cost effective and environmentally sustainable manner including:
  • www.iifiir.org 60 member countries worldwide 500 experts 600 corporate and private members www.iifiir.org
  • www.iifiir.org Services: FRIDOC, a refrigeration portal with over 100,000 references Journals: the International Journal of Refrigeration (IJR – the best scientific journal in its field!), IIR Newsletter, books, Informatory Notes, and Statements. Activities: Conferences Working Parties Research Projects Preparation of Standards
  • www.iifiir.org INCREASING NEEDS OF REFRIGERATION INCREASING ENERGY AND ENVIRONMENTAL CHALLENGES www.iifiir.org
  • www.iifiir.org The refrigerants issue

  • www.iifiir.org Consequences: • Thanks to the Montreal Protocol, CFCs and HCFCs will disappear and the ozone layer will recover. • Now CFCs, HCFCs and HFCs represent about 2% of greenhouse gas emissions. They will represent 7% in 2050. •HFCs are mainly used as refrigerants (80% of use). • Easy to manage • Interests of refrigerant manufacturers • Short lifetime within the atmosphere. • Even if energy issues have a more important impact than refrigerant issues: energy efficiency of the equipment remains a major issue.
  • www.iifiir.org 1st question EU regulation Discussions in UN Conferences 2 Parallel Processes: • Montreal / Vienna ― Kyoto / Rio • North America / Micronesia ― Amendments to the Montreal Protocol since 2009 Pros: the European Union, African and Island countries Cons: India, China, Brazil, Gulf countries • Hot political subject since 2012 • Difficult « negotiations » in Bangkok, October 2013: The state of the art of the discussions
  • www.iifiir.org The time schedule Obtaining an agreement on climate change by key date : 2015 Possible actions before 2020? In any case more delays are needed: 2040 vs 2033 for developed countries? 2050 vs 2043 for developing countries? with a European « advance » of about 10 years? Without any agreement: voluntary commitments • Role of refrigerant manufacturers including China • Price of HFCs, HFOs … • Sector by sector approach • Region by region approach
  • www.iifiir.org Future technical solutions and safety consequences (1) Technologies without refrigerants: • Absorption / adsorption → conf. in the USA • Magnetic refrigeration → WP; conf. in Canada; Elicit project. • Cryogenics → conf. In the Czech Republic • Others Reducing leakage (cf The EU F-gas regulation) → IN (Secondary fluids) Refrigeration charge reduction → IN • Savings and safety 2nd question
  • www.iifiir.org Future technical solutions and safety consequences (2) Choosing a low-GWP refrigerant: other HFCs, mixtures, natural refrigerants • Energy efficiency • Safety issues → GL conferences (China) … Strategic issues: • Standards on flammability • Regulations at international and national levels
  • www.iifiir.org • Phase down very soon of HFCs in Europe followed by everywhere else with or without an international agreement • Different strategies old / new equipment • Training for engineers and technicians is necessary as well as research and technological developments • Belonging to an international scientific and technical network The role of the IIR www.iifiir.org
