Abstract: An energy converter comprises an electrical turbo-machine (101) for converting energy contained by vaporized working fluid into electrical energy, a feed pump (105) for pumping the working fluid in a condensed form to a vaporizer (115), a pre-feed pump (106) for pumping the condensed working fluid to the suction side of the feed pump, and an ejector-pump (108) for pumping the condensed working fluid to the suction side of the pre-feed pump. The energy converter can be based on for example the Organic Rankine Cycle. The feed pump is operated by the electrical turbo-machine, the pre-feed pump is operated by a separate motor (107), and the ejector-pump is operated by a part of the output flow of the pre-feed pump. The ejector-pump facilitates generating sufficient pre-supply pressure for the pre-feed pump during also a starting phase and other situations where the electrical turbo-machine and feed pump are not fully operating.

Abstract: A heat exchanger according to the invention comprises a heat exchanging ele- ment (101) comprising heat transferring walls for preventing first fluid and second fluid from mixing with each other and for transferring heat from the first fluid to the second fluid. The heat exchanger comprises one or more rooms containing phase change material capable of storing heat energy by changing from the solid state to the liquid state and releasing the heat energy by changing from the liquid state back to the solid state. The heat exchanger further comprises a cooling channel system (104) for third fluid for cooling the phase change material so as to protect the phase change material against overheating. A heat exchanger of the kind de- scribed above can be used for example as a vaporizer of an energy converter based on for example the Organic Rankine Cycle.

Abstract: An energy converter based on a thermodynamic energy conversion process comprises an electrical turbo-machine (101) for converting energy contained by vaporized working fluid into electrical energy, a condenser (104) for condensing the vaporized working fluid outputted by the electrical turbo-machine, a vaporizer (105) for receiving a main heat flow from an external heat source and for vaporizing the condensed working fluid, and a feed pump (106) for pumping the condensed working fluid to the vaporizer. The energy converter can be based on for example the Organic Rankine Cycle. The energy converter further comprises a controllable heating device (107) for generating a controllable auxiliary heat flow to the vaporizer so as to at least partly compensate for temporal variations in the main heat flow. Therefore, the energy converter is suitable for being used also with a varying main heat flow which is sometimes unable to maintain the thermodynamic energy conversion process.

Abstract: An energy converter comprises an electrical turbo-machine (201) for converting energy contained by vaporized working fluid into electrical energy, a condenser (204) for condensing the vaporized working fluid outputted by the electrical turbo-machine, a condenser tank (205) for storing the condensed working fluid, and a feed pump (206) for pumping the condensed working fluid from the condenser tank to a vaporizer (216).

Abstract: A high-speed electrical turbo-machine for an Organic Rankine Cycle energy converter is presented. The electrical turbo-machine comprises a stator (101), a rotor (102) for interacting with the stator, and an impeller (103) at an end of the rotor, the impeller being suitable for operating as a turbine for rotating the rotor. The stator comprises a stator core (104) having stator teeth (111, 112) and a stator winding having stator coils (105, 108). The width of each stator coil is one stator slot pitch and each stator coil is arranged to surround only one of the stator teeth so as to minimize the length of the stator end-windings in the axial direction of the rotor. The short end-windings enable the rotor to be shorter, and thus the natural frequencies of the rotor are higher. As a corollary, the critical speeds that excite the natural frequencies of the rotor are higher too.
