Definitions
- the invention relates to an arrangement for converting thermal into electrical energy, consisting of a working circuit with a working fluid for driving a flow machine and a plurality of alternating flow of a cold and warm medium heat exchangers, each of which a n depending on the Temperature of the medium expanding and contracting expansion element is arranged, the temperature-related expansions and contractions are fed to the working circuit via a buffer memory.
- a generic hot water motor for converting thermal energy according to the preamble of claim 1 is known from US Pat. No. 4,283,915.
- the disadvantage of this arrangement is that the working circuit is fed directly to the heat exchangers via the buffer stores. This means that the numerous and long pressure and suction lines required for this must be heat-insulated so that the system remains functional and that only a liquid expansion medium can be used.
- each heat exchanger be assigned a buffer memory designed as a spring for storing a force, each spring being connected to the piston of a pressure cylinder, the working space of which is controlled by controllable valves via suction and pressure lines is connected to the working circuit that drives a turbine with a generator.
- the problems mentioned are avoided by increasing the number and size of the heat exchangers and the driving pistons to such an extent that the expansion medium in each case has sufficient time to convert all the energy supplied.
- the process is slower, but the single pressure cylinder can build a lot more force, and the uniformity of the oil circulation remains due to the larger number of these expansion and
- the expanding and contracting expansion element is advantageously a clamped steel sheet, the temperature-related up and back bulging of which acts on the spring.
- the expansion element has an expanding and contracting liquid or gaseous medium, the volume change of which is fed to the spring via a pressure cylinder.
- Fig. 6 shows the arrangement according to the invention for converting thermal into electrical energy in a schematic representation
- Fig. 7 shows a heat exchanger with a liquid or gaseous medium as an expansion element.
- a heat exchanger 10 has a chamber in which a steel sheet 9 is arranged as an expansion element, which is clamped at its ends.
- Cold water can be supplied to the chamber via a cold water inlet 5 and leaves the chamber again via a cold water outlet 7.
- Warm water can be supplied to the chamber via a hot water inlet 6, which water leaves the chamber via a hot water outlet 8.
- the control of the cold water inlet 5, the cold water outlet 7, the hot water inlet 6 and the hot water outlet 8 is controlled via valves 29 (FIG. 6), a control device with a computer advantageously being used.
- the circuits of hot and cold water remain separate. (However, mixing would also be unproblematic in the event that the cold water from a heating return and the warm water from the heating flow were diverted (combined heat and power plants). Then the outgoing mixed water could be used again without energy loss to the primary energy source, in the case of Heating, be directed so that only the inlets would have to be controlled by the computer in the water circuit).
- a spring 4 is connected to the steel sheet 9 at one end and is connected at its other end to a piston 12 of a pressure cylinder 11.
- FIGS. 1 to 6 also show, the working space 13 of the pressure cylinder 11 is connected via valves 14 to suction lines 25 and pressure lines 15, which are connected to a working oil circuit 2 (FIG. 6) in which a turbine 1 with a generator is arranged is. Furthermore, a pressure expansion tank 3 is connected to the oil circuit 2.
- the controller can release the corresponding valve 14 of the pressure cylinder 11 at any time, so that the 01 present in the work space 13 can be supplied to the oil circuit 2 by the force of the tensioned spring 4 via the associated pressure line 15.
- the arrangement arrives in the position shown in FIG. 3.
- the controller can now open the corresponding valve 14 of the pressure cylinder 11, so that suction is drawn from the oil circuit 2 01 into the working space 13 of the pressure cylinder 11 via the suction line 25, the piston 12 being driven in FIG. 5 by the force of the extended spring m position shown is withdrawn.
- the valves 14 of the individual pressure cylinders 11 are controlled one after the other and at the same time in such a way that the most uniform possible oil circulation is ensured.
- a chamber 18, closed on one side is arranged in the chamber as the expansion element, and there is a liquid or gaseous medium in the chamber.
- the other end of the pipeline is connected to a pressure cylinder 19, the piston 20 of which is connected to the spring 4 designed as a buffer store.
- a transmission could be used on the transmission path to the old cylinder.
- the number of heat exchanger elements with pressure cylinders depends on the temperature difference of the water and the size of the individual heat exchangers, i.e. on the total work performed on the one hand and / or on the desired output on the other.
- the various heat exchanger elements can be set up and arranged in any position because they only have cable connections and hose or pipe connections, which means that a possible larger space requirement would hardly be weighted.
- the materials required for the production were neither expensive nor maintenance-intensive. No component of the system would pose a fire, explosion or environmental hazard.
- the gas could be normal air.
- the hot water engine can also be used to generate renewable energy, as well as waste heat from other processes, which was previously only possible at extremely high steam temperatures and pressures and low efficiency.
- the hot water motor can be connected to any heating system.
