6. Cycles with zeotropic refrigerant mixtures
To avoid the disadvantages of conventional cascade systems, in particular the need for multiple compressors, cycles with zeotropic (or non-azeotropic) refrigerant mixtures can be used, with a single compressor. These types of mixtures can be used for :
mixing cycles without phase separator and with recovery heat exchanger;
mixing cycles with phase separators, or "integrated cascade" cycles.
6.1 Zeotropic mixing cycles without phase separator and with recuperator
Figure 23 a shows a diagram of such a system using a binary zeotropic mixture...
