Volkswagen cars will be using CO2 as future refrigerant for air-conditioning

by Gavril Mankoo

One of the world’s biggest automobile manufacturers, Volkswagen, has decided to bring forth its own carbon-dioxide-based air conditioning systems for its cars in the near future. The Germans abandoned the use of the European Union-recommended HFO-1234yf refrigerant soon after the guys at Daimler found this to be flammable. The HFO-1234yf was developed by Honeywell and DuPont to replace the current coolant, HFC-134a, in an attempt to reduce CO2 emissions.

Daimler earlier conducted its own flammability tests on the coolant and found it to be a volcano waiting to erupt. So, along with BMW and now Volkswagen, the big three manufacturers have decided to step away from the recommendations of the European Union, appealing for a temporary suspension of the new EU law.
