Résumé

This paper shows the state of the art review of alternatives refrigerant in automotive air-conditioning system. An extensive review was conducted and showed an evolution of the thermal performance of the alternative refrigerants (HFC-152a, HFO-1234yf and carbon dioxide) flowing as a refrigerant in automotive air-conditioning system. Experimental results in vehicles are presented, comparing the performance in terms of cooling and fuel consumption. The refrigerant HFO-1234yf has some positives characteristics, the GWP is only 4 and the life time in atmosphere is around 11 days, however, the negative characteristic is associate to the flammability, higher than ammonia and HFC-32 and lower than HFC-152a and propane. The most interesting results showed the cooling time of the interior cabin was, significantly, reduced in all tests performed when the refrigerant used in the system was the carbon dioxide, including results for small power vehicles in comparison with the R134a baseline.
