Transcript

  • 1. A Global Approach to Transitioning to LowerGWP RefrigerantsStephen YurekPresident and CEOAir-Conditioning, Heating, and Refrigeration Institute
  • 2. Refrigerants Are VitalUsed in Air-conditioning,− Vital for personal health, comfort, andwell-beingUsed in Refrigeration− Prolong life of perishable food− Keep life-saving medicines safeImprove− Health, productivity, and safetySave− LivesMassachusetts Institute of TechnologyDepartment of Economics WorkingPaper SeriesAdapting to Climate Change: TheRemarkable Decline in theU.S. Temperature-Mortality RelationshipOver the 20th CenturyAlan BarrecaKaren Clay OlivierDeschenes MichaelGreenstone JosephS.

  • 6. Choosing a RefrigerantRefrigerants have unique operating characteristics:Choice cannot be based on one factor, but instead should be based on an analysis ofall factors:− Safe− Energy efficient− Widely available− Economical− GWPOperating factors can be different:− Pressures− Incompatible lubricants− Incompatible metals and alloys− Flammability levelsNeeds will be different for each application
  • 7. Avoiding Unintended ConsequencesUsed with permission from Rajan Rajendran, Emerson Climate Technologies
  • 8. Refrigerant Research
  • 9. Low GWP Alternative Refrigerant Evaluation ProgramCooperative research program to identify suitable alternatives to high GWP refrigerants.Purpose is NOT to prioritize refrigerants, but rather test and present results in aconsistent manner.Participants− Sixteen (16) U.S. companies/organizations− Five (5) international companies/organizations− Six (6) refrigerant producers supplied thirty-eight (38) refrigerant candidatesTests cover the following applications− Air-conditioners and heat pumps (air-source, water-source, VRF, unitary, mini-split)− Chillers (screw, centrifugal)− Heat pump water heater− Refrigeration (commercial refrigerator, ice machine)− Transport refrigeration− Bus air-conditioning
  • 10. Current Status of Low GWP AREPCompletion of the first round of testing – 3rd quarter of2013− Results posted at:http://www.ahrinet.org/ahri+low_gwp+alternative+refrigerants+evaluation+program.aspxLow-GWP AREP Conference− January 16, 2014 in New York CityPossible second round of refrigerant testing
  • 11. Other ResearchRisk Assessment of Residential Heat Pumps using 2L Refrigerants− Showed very low risk of ignition from the use of R-32, HFO-1234yf, orHFO-1234ze in ducted residential split heat pump systems− October 2012 Report: www.ahrinet.org/technical+results.aspxConfiguration of AC/HP Systems Using Low GWP Refrigerants− Summarized configurations of residential air-conditioning and heatpump systems using hydrocarbons, ammonia, carbon dioxide, andHFO-1234yf while meeting previously defined safety requirements.− January 2013 Report:http://www.ahrinet.org/App_Content/ahri/files/RESEARCH/Technical%20Results/AHRI-8006%20Final%20Report.pdf

  • 13. Education and TrainingWe must come together – globally – to develop aneducation and training planAHRI will lead collaborative U.S. effortWe can ensure a seamless transition to multiplerefrigerants
  • 14. SummaryWe understand policy interest in addressing highGWP refrigerantsAdequate time needed− To properly research alternatives− Engineer products that can use alternativessafely− Develop capacity to manufacture, distribute,and sellWe have a good record as an industry− We must continue to work with policy makersWe must seize the opportunity to approach globalissue in a global not regional fashion
