Term does not apply to upgrades to existing equipment where the refrigerant is not changed. *Abbreviated For complete listing, see EPA Final Rule; go to: See EPA Final Rule; go to: 5

6 Likely Refrigerant Alternatives Emerson s Perspective and Development Path A1 Non-Flammable A2L Mildly Flammable A3 Flammable B2L Toxic, Mildly Flam. Volumetric Capacity/ Pressure Naturals Mildly Flammable (A2L) HFO and Blends Lowest GWP Non-Flammable (A1) HFC/HFO Blends Today s Non-Flammable (A1) HFCs Elevated R-744 (CO 2 ) 1 Medium R-404A Like R-290 (Propane) 3 R-717 (Ammonia) 0 R-455A (HDR-110) 146 R-454C (DR3) 146 R-449A (XP40) 1,282 R-448A (N40) 1,273 R-407A 1,923 R-507A 3,985 R-407C 1,624 R-407F R-404A 1,674 3,943 Low R-134a Like HFO-1234yf <1 HFO-1234ze <1 R-513A (XP10) 573 R-450A (N13) 547 R-134a 1,300 GWP ,300 1,300 4,000 In Production Not SNAP Listed, Next in Development Approved or in Development In Production This List Is Subject to Change.

7 Refrigerant Limitations AHRI and NAFEM continue requesting EPA to approve R-448A and R-449A for MT self-contained equipment R-448A/449A for reciprocating hermetics LT envelope challenges due to high heat of compression Glide considerations Capacity increases from R-404A R-450A/513A for reciprocating hermetics R-450A capacity drops from 134a R-513A near drop-in replacement with no theoretical capacity changes Glide considerations MBP to LBP performance drops and capacity changes; requiring complete system redesign No Silver Bullet Alternative Refrigerant 7

8 Flammable Refrigerants Create Challenges Refrigerants approved by the EPA for some end use applications under Significant New Alternatives Policy (SNAP) Guideline for technicians with info on best practices R-290 (propane) R-600a (isobutane) R-441A (a blend) Limitations No retrofitting of equipment to R-290 allowed; only new equipment Stand-alone equipment only Charge limit of 150 grams (5.3 ounces) Currently no formalized certification of service technicians No channel developed for service replacements for compressors AHJ (authority having jurisdiction) Local authorities such as state, local, as well as fire marshals may have other restrictions Servicing Infrastructure Needs Development; Be Sure to Check AHJ Before Installing Equipment. 8

9 R-290 Commercial Applications IEC/UL/ASHRAE: R-290: U.S. 300 gram charge limit in proposal (CE-2021) A2L: U.S. 1 kg charge limit in proposal (CE-2021) Increasing Charge Limit/Code Standard Revision Proposal Won t Be Implemented Until 2021 at the Earliest. 9

10 Industry Efforts Are Increasing Around Flammable Refrigerants Underwriters Laboratory and ASHRAE Safety standards under revision to include mildly flammable refrigerant (A2L) accommodations. Targeting end of CY U.S.: UL 1995, ASHRAE 15 International: ISO 5149, IEC 60335, EN378 AHRI Flammable Refrigerants Research Subcommittee Identify gaps in flammable refrigerant research Develop road map to complete critical research for safe use Focus on A2L refrigerants Pushing for closure on items by end of 2017 Next building code cycle is , so Building Codes for Mildly Flammable (A2L s) Refrigerants Being Expedited for Adoption in 2021 Building Codes 10
