  • 9. Key elements to take into account: - Reducing greenhouse gases emissions = various solutions:  Reducing leakage  Reducing the refrigerant charge  Choosing a low-GWP refrigerant  Reducing the energy consumption - The evolution of regulations:  The F-gas regulation and its review in Europe  Montreal Protocol obligations and the current discussions on HFCs  Safety regulations - Industrial strategies:  Refrigerant manufacturers  Refrigerant prices  InstallersInternational Institute of - Each case is different:Refrigeration  Age of the equipment  Size of the equipment and use of it  Location of the equipment  Staff experience
  • 10. Reducing greenhouse gases emissions = Various solutions 1/ Reducing leakage  Variability -> Margins for progress Example: in the EU (30% in the 80s -> 5% and less)  Key factor: the EU example The difficulty: training. 2/ Reducing the refrigerant charge  Issue of safety + GHG emissions: research and development for all refrigerants  Secondary refrigerantInternational  Microchannels Institute ofRefrigeration 3/ Choosing a low-GWP refrigerant  What is a low-GWP refrigerant?
  • 11. ../.. Reducing greenhouse gases emissions = Various solutions  The TEAP report: regulation challenge  All « very-low-GWP refrigerants » present safety risks andInternational drawbacks: flammability, toxicity, corrosion, pressure. Institute ofRefrigeration all need adaptation of the equipment but HFOs need the least: can be a good solution for drop-in. However, they are considered as HFCs, thus with the same kind of regulations as for other HFCs.
  • 12. ../.. Reducing greenhouse gases emissions = Various solutions 4/ Reducing energy consumption  The energy consumption of the equipment has the main impact on GHG emissions  Countries need to reduce the energy consumption for environmental reasons + electrical capacity reasons  The price of electricity will increase: new sources of energy have higher costs Changing the system because of the refrigerant issue must take intoInternational account a reduction in the energy consumption. Institute ofRefrigeration
  • 13. The evolution of regulations 1/ The F-gas regulation review for the European Union = first step for a phase-down of HFCs The new regulation will be stricter. Ideas:  banning pre-charging of equipment (impact on air-conditioning equipment)  reducing the charge limit for controls consequences at least in neighbouring countries 2/ Montreal Protocol obligations and the current discussions on HFCs  HCFC phase-outInternational  and HFC phase-down in the future (very probably) Institute ofRefrigeration  sooner, international financial incentives for « low-GWP » refrigerant solutions / « high-GWP » refrigerant solutions (very probably)
  • 14. ../.. The evolution of regulations 3/ Safety regulations  A barrier for ammonia, a barrier for hydrocarbons, but  Ammonia is still recognized as the most efficient refrigerant The example of France: regulations can change  Hydrocarbons are a good solution for low charges.International The US example: regulations can change; Institute ofRefrigeration barriers would be similar for HFOs and hydrocarbons
  • 15. Industrial strategies 1/ Refrigerant manufacturers  The will to have only one market = lobbying of Dupont + Honeywell for HFC phase-down according to the Montreal Protocol; lobbying for acceptance of HFOs.  Difficulties: manufacturers in developing countries; industrial capacity vs the huge market for car air conditioning.  HFOs will be the refrigerant choice of car manufacturers in Europe; then in the US, then all over the world.International Institute of  HFOs manufacturers are developing products for other uses:Refrigeration foams, commercial refrigeration, stationary air conditioning…
  • 16. ../.. Industrial strategies 2/ Refrigerant prices  There will be shortages: - shortage of HCFCs because of phase-out in developed countries (already in force) and because of manufacturers’ forecasts. - shortage of HFCs produced by HFO manufacturers: they need to convert their plants Their price will increase  The development of HFOs was expensive: their price will be higherInternational than those of HCFCs and HFCs Institute of Even if moving to natural refrigerants is a costly investment, runningRefrigeration costs will be lower.
  • 17. ../.. Industrial strategies 3/ Installers 2 kinds of positions:  Limiting the competition (cf AREA’s position):  Resistance to change, because of lack of expertise, lack of training (some European countries still have not implemented the F-gas regulation!) Working with the installers and funding training when implementingInternational Institute ofRefrigeration an HCFC phase-out plan is a necessity.
  • 18. Each case is different 1/ Age of the equipment  For relatively new equipment: Drop-in solutions with HFCs and maybe HFOs in the future.  For old equipment: replacement solutions, taking into account the energy consumption + solution with natural refrigerant if possible (safety constraints, quality of maintenance) and low charge, even if the investment cost is higher.International 2/ Size of the equipment and use of it Institute ofRefrigeration  No universal solution Refrigerant properties are different
  • 19. ../.. Each case is different 3/ Location of the equipment  Constraints related to the local environment (regulations on ammonia for instance)  Ambient temperature constraints (CO2 efficiency is better in « cold » countries than in « warm » countries for instance). 4/ Staff experience  The maintenance issue is a key elementInternational / leakage Institute ofRefrigeration / safety
  • 20. CONCLUSION  Presentation of the key elements of a strategic plan  However, numerous current technical developments on low-GWP refrigerants and on more efficient equipment  Need for updated information in administrations, in companies, in universities The IIR can help you Become a member.International Institute ofRefrigeration See our Web site: www.iifiir.org
