They could be your home air conditioner, your automobile, your refrigerator, or your local grocery store. They were everywhere. In the 1960’s there were a few more CFC/HCFC refrigerants invented, including R-502, that led to even more explosive growth.

As a result, working with R744 will require new service equipment meeting the relevant SAE standards, as well as technical training about the major differences. The decision by some automotive manufacturers to adopt R744 came from flammability concerns about R1234yf, particularly Mercedes-Benz parent company Daimler.

Carbon dioxide (R744) is over a thousand times less harmful on the atmosphere than the conventional R134a refrigerant. It has an excellent cooling capacity, it is not flammable and readily available worldwide at low cost. Leading bus manufacturers already launched the first models with R 744 air conditioners.

26 Oct 2015 Estimates vary, but CO2 refrigerant—known in HVAC parlance as R744—is yet another trick automakers can wield to increase efficiency and
