Abstract
A Rankine cycle apparatus includes a pump, an evaporator, an expander, a condenser, and an internal heat exchanger. The internal heat exchanger allows heat exchange to take place between a working fluid discharged from the expander and a working fluid discharged from the pump. A temperature of the working fluid at an inlet of the expander is set so that a temperature of the working fluid at an outlet of the expander be higher than a saturation temperature on a high-pressure side of the cycle.

1-11. (canceled)
A Rankine cycle apparatus comprising:
- a pump;
- an evaporator;
- an expander;
- a condenser;
- and
- an internal heat exchanger that allows heat exchange to take place between a working fluid, being a single organic fluid, discharged from the expander and the working fluid discharged from the pump, wherein
- the Rankine cycle apparatus is configured such that:
- a temperature of the working fluid at an inlet of the expander is set so that a temperature of the working fluid at an outlet of the expander is higher than the saturation temperature on a high-pressure side of the cycle;
- and
- the working fluid at an inlet of the evaporator is in a liquid phase.
A method for operating a Rankine cycle apparatus, the Rankine cycle apparatus comprising:
- a pump;
- an evaporator;
- an expander;
- a condenser;
- and an internal heat exchanger that allows heat exchange to take place between a working fluid, being a single organic fluid, discharged from the expander and the working fluid discharged from the pump,
- the method comprising setting a temperature of the working fluid at an inlet of the expander so that a temperature of the working fluid at the outlet of the expander be higher than a saturation temperature on the high-pressure side of the cycle and the working fluid at an inlet of the evaporator is in a liquid phase.
