German car manufacturer Volkswagen will opt for CO 2 mobile air-conditioning (MAC) systems in another series of cars by the end of 2019 – its electric car ‘ID’ series, according to reports from German environmental journalist Joachim Wille in Frankfurter Rundschau and Klimareporter on 11 August 2018. This is the second time Volkswagen has stated it is opting for CO 2 MAC in a series of cars.

2015-07-02 · R744 Hazards. R744 is not flammable, but its high pressures, toxicity at high concentration, and potential for dry ice formation must be taken into account when applying and handling. This post explains some of the hazards and provides very general guidance on reducing them. 1. Asphyxiation. R744 is odorless, heavier than air, and is an asphyxiant.
