Abstrakt
The conventional refrigeration ejector cycle utilizes constant temperature process during motive heat consumption needed for vapor generation. This may be thought as the main restriction since it results in required significant mass flow rate with small temperature drop of a heating fluid. In contrary, the large change of temperature and small flow rate of the water in order to provide required heat flux is more economically advantageous. In some cases, however, either requirements can not be fulfilled. One of the possible approaches to reduce this restriction is application of a zeotropic mixture as the working fluid for the conventional ejector cycle. The paper deals with thermodynamic analysis of low GWP refrigerant mixtures applied for ejection cycle. The results show that depending on the type and proportion of mixed refrigerants the temperature of the heating medium change from 5 to 25 K and more.
