Stephen Yurek - AHRI - SUPERARE GLI ATTUALI REFRIGERANTI

  1. 1. A Global Approach to Transitioning to LowerGWP RefrigerantsStephen YurekPresident and CEOAir-Conditioning, Heating, and Refrigeration Institute
  2. 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. 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. 7. Avoiding Unintended ConsequencesUsed with permission from Rajan Rajendran, Emerson Climate Technologies
  8. 8. Refrigerant Research
  9. 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. 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. 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. 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. 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
