It may come as a surprise, but carbon dioxide, the infamous greenhouse gas driving climate change, is also a leading contender in the replacement of hydrofluorocarbons in the next-generation of “green” refrigeration systems. It offers many advantages over second and third generation refrigerants, including higher volumetric cooling capacity, lower operating temperatures, non-flammability, reduced operating costs, and lower global warming potential.
