In order to mitigate the high impact of traditional refrigerants in global warming, low global warming potential (GWP) refrigerants attract more attention in the investigation and development of next generation refrigerants in accordance to the international agreements. Unfortunately, unlike the high-GWP refrigerants the low-GWP candidates are generally more flammable under atmosphere conditions. Along with the development of heat pump systems, those low-GWP refrigerants will be applied even under elevated pressures. To safely handle these novel refrigerants under the new application scenarios a detailed understanding of the oxidation and pyrolysis mechanisms of those hydrofluorocarbons and their underlying chemical kinetics is essential and therefore is an important focus of this proposal. To obtain fundamental understanding of the underlying chemistry, experimental investigations under well-defined conditions are indispensable. The experimental data can provide a basic knowledge of the conversion behavior and therewith sub-mechanisms for oxidation and pyrolysis processes can be well constructed. Complement to experiments, theoretical investigations can provide more insight to single conversion channel that will further refine the kinetic models. The kinetic investigation on the low-GWP refrigerants is still scarce although their significance has been well recognized.
