2 Honeywell A History of Innovation CFCs HCFCs HFCs HFOs Very high ODP & GWP High ODP and GWP ODP=0, but high GWP ODP=0 GWP low or ultra low R12 R123 R22 R410A R407C R134a R407F Solstice HFO Family Next Generation refrigerants are based on 4 MAJOR Considerations Energy efficiency Environmental compliance Safety Cost - Affordable

3 EU Market Drivers 2015 F-Gas Regulation Force Industry to reduce reliance on High GWP refrigerants 100% - Restrictions on Use (Bans) - Phase Down of HFC s (Quota) - Leak Reduction Increasing focus on Energy Reduction ( ) Environmental Responsibility (Corporate) Sustainability ( + Corporate) 93% 63% CO2eq quota is expected to:- Reduce the placing on the market of high GWP products (e.g. R-404A / 507) Create a demand for reclaimed High GWP products Increase demand for lower GWP refrigerants (new and retro-fits) Restrictions of Use will force:- OEM s, consultants and endusers to design products to suit <150GWP refrigerants Industry to re-consider sustainability / lifetime of products 45% 31% 24% 21%

4 F-Gas Control of Use in Commercial Refrigeration New Installation Bans* (only main bans affecting Refrigeration shown here) Stationary Refrigeration Equipment requiring HFC >2500 GWP New Commercial Refrigerators / Freezers (hermetically sealed systems) >150 GWP Domestic refrigerators and freezers using HFC s >150 GWP New Commercial Refrigerators / Freezers (hermetically sealed systems) >2500 GWP Centralised multipack systems >40kW capacity using HFC >150 GWP / except primary circuit (not distributed) of cascade system where <1500 GWP is acceptable RAC & H/Pump equip. precharged with F-gases must be included in a registered Quota system beginning 2017 Virgin F-gases >2500 GWP for servicing ref equip. With charge size of >40 T CO₂-eq (~10kg ) Recycled and reclaimed F- gases with >2500 GWP for servicing ref equip with a charge size of >40 T CO₂-eq Exemptions include Military equipment and refrigeration applications below -50 Deg C Maintenance & Service Bans* (only those affecting Refrigeration shown here) NOTE: R-407F and R-448A can be used to service / retrofit High GWP (>2500) after without end date (beyond ) *Note This document is not a comprehensive collection of all the 2015 F-gas bans
