TS Diagram of a Carnot vapor compression refrigeration cycle.
In Lesson A, we presented the problems associated with using the Carnot Cycle as a practical model for a real vapor-compression refrigeration cycle.
  • Most compressors do not work well on two-phase mixtures
  • Turbines are not designed to handle vapor-liquid mixtures.
In this lesson, we present a practical cycle that approximates the

Carnot vapor-compression refrigeration cycle

. We will also discuss


and how to select one.
