1. Summary of the rapporteurs Key conclusions of the Workshop on HFC Management: Technical issues K. Shepardson / S. Sicars OEWG Bangkok 22 April 2015

2. Technology HFCs – Used in a number of sectors, sub-sectors – Factsheets Alternatives used – Different regions, sub-sectors – Sometimes not widespread Not commercialized – Condensing units/commercial refrigeration – Large MAC – Medium size air-to-air A/C Economies of scale important April 22, 2015 OEWG Bangkok K. Shepardson / S. Sicars

3. Technology (cont.) Main barriers: – Investment costs – Lack of regulations – Components – Technician training – Safety standards Subsectors need to be assessed individually April 22, 2015 OEWG Bangkok K. Shepardson / S. Sicars

4. Cross-cutting issues Energy efficiency Costs and intellectual property rights Safety and flammability High ambient temperature Policy and regulatory framework Service sector and training needs Special challenges for A5 Countries April 22, 2015 OEWG Bangkok K. Shepardson / S. Sicars

5. Take-away messages Alternative solutions in almost all sectors Accounting for energy efficiency Need for being adaptive and flexible New technologies to new markets Tailored solutions April 22, 2015 OEWG Bangkok K. Shepardson / S. Sicars

6. Next steps Ongoing transition from HCFCs in Article 5 countries: Challenges and opportunities for the introduction of lower GWP alternatives in the near term Non-Article 5 countries can accelerate adoption of these technologies even further Immediate and substantial impact: Subsector of commercial refrigeration where R-404A is being used, even with transition to a lower GWP HFC Improve responsible use of refrigerants for the installed base: improvement of manufacturing process and servicing Raising awareness and communication efforts, also outside the Montreal Protocol April 22, 2015 OEWG Bangkok K. Shepardson / S. Sicars
