Introduction
The thermodynamic vapor cycles working with saturated vapor have broad technical applications. This is based on certain properties of the saturated vapor: isothermal course of the isobaric processes resulting in the shape of the Clausius–Rankine cycle that is close to that of the Carnot cycle, high intensity of heat transfer during the working fluid phase change and, also, low value of the liquid compression work. However, the above advantages have been in fact formulated for the traditional steam power plants with water as the working fluid.
