Abstract
A process and apparatus by means of which the premier vapor cycle, known as the Carnot cycle, can be approximated in practice, involve the application of novel energy-efficient, mixed phase, high volume-ratio fluid-handling machinery to a single-component working fluid that exists during certain processes as a mixture of fine droplets of saturated liquid in saturated vapor. This combination of fluid-handling machinery and the saturated mixed-phase working fluid enables the approximation of isentropic saturated liquid/vapor expansion and compression. These process approximations, in addition to isothermal heat addition and rejection, enable Carnot heat engine, refrigeration and heat pump cycles to be approximated.
