Abstract
A CHP system includes a combustor (heat source), a Rankine cycle apparatus, and a second heat exchanger. The Rankine cycle apparatus includes, as an evaporator, a first heat exchanger that absorbs thermal energy produced in the combustor. The second heat exchanger is located closer to the combustor than is the evaporator, absorbs thermal energy produced in the combustor, and transfers the thermal energy to a heat medium.
Claims16
A combined heat and power system comprising:
- a heat source;
- a Rankine cycle apparatus comprising, as an evaporator for heating a working fluid, a first heat exchanger that absorbs thermal energy produced in the heat source;
- a second heat exchanger that is a heat exchanger for heating a heat medium different from the working fluid of the Rankine cycle apparatus, that is located closer to the heat source than is the first heat exchanger, and that absorbs thermal energy produced in the heat source and transfers the thermal energy to the heat medium;
- and
- a fluid circuit that includes the second heat exchanger, wherein
- the working fluid is an organic working fluid,
- the heat medium is in a single-phase state selected from a gas-phase state and a liquid-phase state in the second heat exchanger,
- no heat exchanger used to heat the working fluid is provided upstream of the second heat exchanger in a flow path of a medium that imparts the thermal energy to the working fluid and the heat medium, and
- the fluid circuit is not fluidly connected with the flow path of the medium that imparts the thermal energy to the working fluid and the heat medium.
