  19. 19. 20
  20. 20. R744 Heat pump investigations in 2001 21
  21. 21. World’s first R744 Car Air Conditioning system Courtesy, Denso and even with a heat pump option! 22
  22. 22. 23
  23. 23. 24
  24. 24. TIER I suppliers were ready for R744... Wolf (2007) 25
  25. 25. Test Results - R744 MAC 26
  26. 26. Development achievements ! System Performance Wieschollek and Heckt (2007) investigated the fuel consumption of a Toyota Yaris equipped with a 1.0 dm3 petrol engine, a conventional HFC MAC system and an R744 MAC system. Applying the R744 MAC system reduced the additional fuel consumption due to AC by: 25%, 0,56 dm3/100km in a NEDC at 35 °C ambient temperature (HFC134a 1.97 dm3/100km versus R744 1.41 dm3/100km). 27
  27. 27. Medium size car, Europe 28
  28. 28. Medium size car, Europe NEDC Fuel over-consumption HFC-134a versus R744 Fuel over-consumption [l/100km] Text Ambient Temperature [°C] 29
  29. 29. Small car, Europe 30
  30. 30. LCCP - Europe ! Results, case study: Europe ! HFC MAC system emits GHG: ! 2.4 - 3.5 metric tonnes (Athens, 50 depending on leakages) –6 ! Up to 1.2 metric tonnes 3% (Trondheim, Norway) based on ! 12.500 km/a ! 12 years of driving Ref: 2nd International Workshop on Mobile Air Conditioning and Auxiliary Systems. Orbassano 2007 ! 50 – 63 % reduction if R744 is applied 31
  31. 31. LCCP - Europe ! Results, case study: Europe ! HFC MAC requires fuel: ! 824 liters in Athens 50 ! 53 liters in Trondheim –6 25% 3 based on % ! 12.500 km/a ! 12 years of driving Ref: 2nd International Workshop on Mobile Air Conditioning and Auxiliary Systems. Orbassano 2007 ! 25 % fuel savings if R744 is applied 32
  32. 32. LCCP - China & India ! Results, case study: India & China ! HFC MAC system emits GHG: ! 10 to 14 metric tonnes (India) 50 ! 5 metric tonnes (China) –6 40%3 % based on ! 15.000 km/a ! 15 years of driving Ref: 2nd International Workshop on Mobile Air Conditioning and Auxiliary Systems. Orbassano 2007 ! 40 % reduction if R744 is applied 33
  33. 33. LCCP - China & India ! Results, case study: India & China ! HFC MAC requires fuel: ! 3039 - 3509 liters in (India) 50 ! 2170 - 2654 liters in (China) –6 32 40 3 % based on - 4% 0% ! 15.000 km/a ! 15 years of driving Ref: 2nd International Workshop on Mobile Air Conditioning and Auxiliary Systems. Orbassano 2007 ! 32 - 40 % fuel savings if R744 is applied 34
  34. 34. LCCP Summary - Asia The estimated fuel saving potential and reduction of GHG emissions per 1.000.000 cars by introducing R744 MAC systems instead of continuing with HFC 134a MAC units in Asia are: ! in the Shanghai area: ! 18.000 m3 of petrol ! 172.000 metric tonnes of GHG emissions ! in New Delhi: ! 57.000 m3 of petrol ! 300.000 metric tonnes of GHG emissions (CO2 eq.) !

  35. 35. CO2 MAC today & tomorrow ๏ conventional passenger cars: R744 has been sidelined by OEMs in Europe, USA ๏ electric vehicles: R744 has still high potential, due to its compatibility with electronic components and its heat pump functionality allowing for both cooling and heating ๏ development of compact and efficient thermal management system for li-ion system in electric vehicles1 ๏ buses: R744 systems are now introduced by Germany’s biggest public transport company in Berlin to cool its bus fleet ๏ trains: potential currently tested in real-life conditions2 1 http://www.r744.com/articles/2009-09-18-iaa-ixetic-displays-r744-lithium-ion-battery-cooling-for-evs.php 2 http://www.r744.com/articles/2010-04-12-exclusive-interview-with-petter-neksa-about-the-future-of-r744.php
  36. 36. CO2 beyond MAC ๏ heat pumps: used in more than 2 million residential, commercial, industrial Japanese Eco-Cute models; rising interest from Europe, North America ๏ supermarkets: cascade systems accepted as standard option in Europe; 100% market share for HFC-free systems in Denmark; strongly rising markets in Germany & UK; rising interest in USA/ Canada; more and more global food retailers committed to R744 ๏ beverage coolers: commitment of Coca-Cola and other consumer brands to invest only in CO2 (and hydrocarbons) as the most sustainable refrigerant available ๏ still higher future technology potential
  37. 37. take home message R744 is the global MAC refrigerant for the long-term future with the highest confidence regarding safety, fuel efficiency, flexibility regarding future developments (heat pumping units) and system improvement potential!
