Abstract
The application relates to a binary cycle power system for generating electrical power. The system comprises a heat exchanger for evaporating a first fluid, a turbine converter, an electrical generator, and a first condenser for condensing the evaporated first fluid. The turbine converter converts energy of the evaporated first fluid to mechanical energy and the electrical generator generates the electrical power from the mechanical energy. The heat exchanger is a second conderser, which is a part of a heat pump that transfers heat from a second fluid circulating in the heat pump to the first fluid so that the first fluid evaporates.
Claims6
A binary cycle power system for generating electrical power, comprising
- a heat exchanger for evaporating a first fluid,
- a turbine converter,
- an electrical generator, and
- a first condenser for condensing the evaporated first fluid,
- wherein the turbine converter converts energy of the evaporated first fluid to mechanical energy and the electrical generator generates the electrical power from the mechanical energy,
- wherein the heat exchanger is a second condenser, which is a part of a heat pump and configured to transfer heat from a second fluid circulating in a closed channel system of the heat pump into the first fluid so that the first fluid evaporates, and
- wherein a part of the closed channel system of the heat pump is configured to be immersed into a waterbody to allow the heat to be extracted from the waterbody and transferred to the second fluid, which circulates in the partly immersed closed channel system.
A generation method for generating electrical power in a binary cycle power system, comprising at least steps of
- circulating a second fluid in a closed channel system,
- extracting a heat from freshwater or seawater to the second fluid, which circulates in the closed channel system,
- transferring, by a heat exchanger operating as a second condenser, the heat from the second fluid circulating in the second condenser to a first fluid to evaporate the first fluid,
- converting, by a turbine converter, energy of the evaporated first fluid to a mechanical energy,
- generating, by an electrical generator, the electrical power from the mechanical energy, and
- condensing, by a first condenser, the evaporated first fluid,
- wherein the closed channel system is partly immersed into a waterbody to allow the heat to extract from the waterbody to the second fluid, which circulates in the partly immersed closed channel system.
