MAC workshop to examine alternative refrigerants |
 |
The 2nd International Workshop on Mobile Air Conditioning will explore CO2 (R744) and alternative refrigerants to reduce greenhouse gas emissions and fuel use. The meeting comes at a key time for carmakers to decide whether to follow the VDA lead and opt for CO2.

The event on 29-30 November will provide a forum for experts to exchange views on latest technical developments and legal requirements in the field of Mobile Air Conditioning. Given the EU-wide phase-out of the current refrigerant HFC-134a from 2011, scientists, suppliers and OEMs will this year discuss new refrigerants complying with the GWP (Global Warming Potential) limit of 150. Presentations will mainly focus on the natural refrigerant CO2 (R744), with some interventions also providing latest updates on chemical alternatives.
|
The event, organized by ATA (Associazone Tecnica dell' Automobile) and Centro Ricerche Fiat, will evaluate new components and systems from an academic point of view but will also address the issues of cost-effectiveness, fuel efficiency, and environmental benefits from an industry perspective. In the afternoon, the workshop will present four vehicles equipped with R744, R152a, a low-GWP alternative, and an enhanced R134a system to compare performance levels.
