2nd European Workshop on Mobile Air Conditioning and Auxiliaries

DuPont Refrigerants and Honeywell presented data on a new refrigerant candidate for Mobile Air Conditioning (MAC) at the 2nd European Workshop on Mobile Air Conditioning and Auxiliaries, November 29th, 2007 in Torino, Italy. The new candidate, HFO-1234yf, is currently being evaluated by automotive manufacturers. Preliminary data suggests that HFO-1234yf has the potential to deliver the best balance of properties and performance, versus existing candidates, such as CO2 (R744) and HFC-152a, in MAC systems globally.
