Résumé

All refrigerants have advantages and disadvantages and so has carbon dioxide, but in a properly designed system, neither the high triple point nor the low critical temperature has any larger importance. As an extra benefit to the excellent thermal properties of CO2, comes the lack of negative environmental effects, the cheap price and the availability. The article gives a comparison of carbon dioxide and some refrigerants, which all could feasibly be used in the low temperature stage of a cascade system at temperature levels typically found in supermarkets, cold stores and food processing plants.
