Abstract
An improved thermal energy transfer apparatus and associated working fluid employs a supersonic compressor in place of a conventional turbine-compressor unit within a Rankine heat engine powering a vapor compression heat pump. The compressor comprises a supersonic nozzle having an inlet section which converges to a throat region from which is diverging outlet section extends. The inlet section is coupled in the fluid flow path of the heat engine at the boiler outlet, while its outlet section is coupled to a downstream condenser. The working fluid from the evaporator of the heat pump is entrained at a point downstream of the throat region where the pressure in the nozzle is lower than the pressure at the exit of the evaporator. The pressure of the second working fluid from the heat pump is lower than that of the exiting fluid (and the input fluid from the heat engine). The two fluids are mixed together and decelerated by the nozzle, causing the working fluid exiting the nozzle to be compressed to a pressure intermediate that of the heat engine fluid and the heat pump fluid. The working fluid is preferably comprised of at least one fluid compound selected from the group consisting of…
