New technology: CO2 (R744) as an alternative refrigerant.

Author(s) : MAGER R.


This presentation concerns the use of CO2 as a refrigerant in the air-conditioning systems of motor vehicles. Following a rundown of the properties of this fluid, the author gives a progress report on the current uses in air conditioning and commercial and industrial applications. A comparison is made with R134a, showing improved performances (time of temperature decrease). Technological considerations are presented, in particular showing a reduction of the emissions due to leaks and a reduction in fuel consumption.
