Résumé

Refrigerant mixtures are regarded as potential alternatives in the field of air conditioning and heat pumps because rare pure refrigerants can totally meet all the requirements of environmental, thermodynamic and safety properties. Meanwhile, as an effective means, vapour injected system is widely applied to improve the system performance of heat pump under large compression ratio,
especially the intermediate heat exchanger system for refrigerant mixtures. However, with regard to this potential system, it is still lack of further analysis, especially the exergy analysis. In this study, the exergy destruction method is applied to analyse quantitatively temperature matching degree of heat exchangers and system performance. Meanwhile, multiple working conditions are covered in analysis.
