This year's "Review of Automotive Air-Conditioning" featured 33 presentations in 3 days. Under the title "Technology Friendly to People and the Environment" speakers focused on sustainable and cost-effective solutions to increase passengers' comfort and safety, cut down fuel consumption, and reduce greenhouse gas emissions from Mobile Air Conditioning (MAC).
Several experts supported the use of carbon dioxide as the leading refrigerant in MAC worldwide, presenting latest developments in automotive components for R744.

Obrist Engineering highlighted the change to the low Global Warming Potential (GWP) refrigerant R744 as a key strategy to reduce direct and indirect greenhouse gas (GHG) emissions from MAC. Obrist’s tests have lead to the following results:
|
|
|
- A global introduction of R744 at an early stage will reduce direct GHG emissions significantly
- A switch from R134a to R744 would lead to a 12% total GHG emission reduction
- The Coefficient of Performance (COP) of R744 systems at medium ambient temperature is considerably higher than that of R134a, and its cooling capacity at high ambient temperature is equal or better than R134a
- The increased performance density of R744 leads to smaller and lighter components also suitable for small car low cost air conditioning
Ixetic announced its range of R744 compressors for compact cars. Their fixed-displacement compressor will meet low cost targets, and has a better coefficient of performance than HFC-134a, meaning lower fuel consumption to run the MAC system.

"The response to R744.com was very positive," said Marc Chasserot, Marketing Manager Shecco Technology, after his presentation of the new web service. "There is a growing demand for an online service on CO2 Technology, which was reflected during the conference in the interest on the website and the features we will be launching soon," he added.
