Refrigerant & Energy Regulations Update Focus on Refrigeration Applications Rajan Rajendran Emerson Climate Technologies
Agenda A Quick History on Refrigerant Progression Environmental Protection Agency (EPA) – First rule to approve new refrigerants in applications – Second rule to delist some existing refrigerants by application – Emerson view and what’s next Department of Energy (DOE) – Commercial refrigeration equipment, ice machines, and walk-in coolers and freezers Summary
Ozone Hole: Reason for R12 and R22 Phase-out (Exposure to UV Radiation Leads to Skin Cancer) Montreal Protocol, Signed on Sept. 16, 1987, Bans CFCs & HCFCs

Environmental Protection Agency (EPA): What Is SNAP? What Are NOPRs? SNAP stands for Significant New Alternatives Policy – Environmental Protection Agency’s program to approve alternative refrigerants to ozone-depleting potential CFCs, HCFCs – Approval specific to refrigerant and application – Website: http://www.epa.gov/ozone/snap/index.html When EPA approves a refrigerant, a Notice of Public Rulemaking (NOPR) is issued in Federal Register – Public has 60 days to review and comment – All details on how to submit comments are provided in the NOPR
EPA’s First NOPR This Summer Published on July 9; comments were due Sept. 8 Listed new flammable A2 and A3 refrigerants and revised venting prohibitions – Stand-alone commercial refrigerators and freezers: R600a, R441A (150 g) – Household refrigerators and freezers: R290 (57 g) – Vending machines: R600a, R290 (150 g) – Self-contained room AC, PTACs, PTHPs, window AC and single-room portable AC: R290, R32, R441A (subject to UL 484 limits) https://www.federalregister.gov/articles/2014/07/09/2014- 15889/protection-of-stratospheric-ozone-listing-of-substitutes-for- refrigeration-and-air-conditioning-and
Second NOPR for Delisting Certain HFCs by Application In 2013 and early 2014, EPA held stakeholder meetings to get input on which HFCs, if any, could be delisted The NOPR to delist was published on August 6 – Comments were due on October 20; comment period closed and all comments have been posted on public website Links to documents: Fact sheet: http://www.epa.gov/ozone/downloads/SAN_5750_SNAP_Status_Change_Rule- Fact_Sheet_070714.pdf NOPR: http://www.gpo.gov/fdsys/pkg/FR-2014-08-06/pdf/2014-18494.pdf Comments: http://www.regulations.gov/#!docketBrowser;rpp=25;po=0;dct=PS;D=EPA-HQ-OAR- 2014-0198
Second NOPR Refrigeration and Air Conditioning End Uses Impacted Currently Included – Retail food refrigeration includes all cold storage cases designed to chill food for commercial sale. In addition to grocery cases, the end use includes convenience store reach-in cases and restaurant walk-in refrigerators. – Vending machines are self-contained units which dispense goods that must be kept cold or frozen. – Motor vehicle air conditioning systems, or MVACS, provide comfort cooling for passengers in cars, buses, planes, trains, and other forms of transportation. Not Included, but Seeking Comment – Industrial process refrigeration systems cool process streams in industrial applications. – Cold storage warehouses are used to store meat, produce, dairy products, and other perishable goods. – Commercial ice machines are used in commercial establishments to produce ice for consumer use, e.g., in hotels, restaurants and convenience stores. – Refrigerated transport moves products from one place to another while maintaining necessary temperatures, and include refrigerated ship holds, truck trailers, railway freight cars, and other shipping containers Foam and Aerosol Also Impacted http://www.epa.gov/ozone/snap/refrigerants/index.html

What Is Next for Delisting Proposal? 120 comment letters were submitted to the EPA – Majority of the comments requested delays and exemptions from delisting – A few supported the EPA’s actions and asked for more stringent delisting Next steps for the EPA – Review all comment letters – Publish final rule, and include responses to all the comments from stakeholders and public – Expect final rule before middle of 2015 In the meantime, EPA can be expected to continue approving new lower GWP refrigerants in specific applications

Summary Over the next five years, expect – R404A to be delisted and no longer used in new equipment – New R22 retrofit (non-flammable) refrigerants available – R404A retrofits to new lower GWP (non-flammable) refrigerants – New mildly flammable and flammable refrigerants in self-contained and walk-in systems CO2 systems will grow — cascade, transcritical and secondary Energy regulations will impact equipment manufacturers and installers Training and keeping up with technology and changes very important Emerson and E360 aim to help you with that!
