Kyoto Protocol and environmentally acceptable Synthetic halocarbon refrigerants
Annotation
The paper deals with the expected impact of the safety and environmental issues concerning the use hydrofluorocarbons (HFCs) and presents a status report on alternative compounds under development. A brief overview is provided of the key market segments and end uses of chlorofluorocarbons (CFCs) and hy-drochlorofluorocarbons (HCFCs). As a result of scientific studies an international agreements has been reached called the Montreal and Kyoto Protocols. The protocols call for the regulation of consumption of CFCs and HCFCs that depleted the ozone layer and HFCs refrigerants that are responsible for predicted global warming trend. To be acceptable as a modern refrigerant a fluid must satisfy a variety of criteria, in-dicated in this paper, as examples the requirements of a nonflammable refrigerant, the atmospheric lifetimes, ozon depletion and greenhouse effect potentials.
