Definitions
- the invention relates to a gas expansion element for an arrangement for converting from thermal to motor Energy, especially for a hot water engine from a closed one filled with a gas or a gas mixture Pressure vessel that has a sliding piston is effectively connected to the arrangement and an upper Injection opening for hot water and a lower water drain opening Has.
- From US-A-4 283 915 is an arrangement for converting thermal known in motor energy, each one Feed for hot water and one for cold water, where a certain temperature difference between the warm and the cold water prevails.
- the hot and cold water are alternately passed through pipes of a heat exchanger, to expand and contract a working fluid.
- the working cycle is above a boiling point of the working fluid.
- Using check valves becomes a relatively high pressure to operate the assembly ensured.
- the use turns out to be of the heat exchanger as a disadvantage, since such a tube heat exchanger with a large technical effort only has a very limited efficiency and is dependent of the nature of those flowing through and around it Media is relatively susceptible to interference.
- DE 197 19 190 C2 discloses an arrangement for converting thermal energy into electrical energy a working circuit with a working fluid to drive one Fluid machine and a variety of alternating heat exchangers flowed through by a cold and warm medium consists. There is one in each of the heat exchangers Depending on the temperature of the medium expanding and contracting expansion element arranged, the temperature-related Expansions and contractions over one Buffer memory can be fed to the working cycle. to Every heat exchanger stores a force as a spring trained buffer memory associated with each spring is connected to the piston of a pressure cylinder, the working space each via controllable valves via suction and Pressure lines is connected to a working oil circuit, that drives a turbine with a generator.
- This arrangement has a relatively complex structure, in particular the buffer storage designed as springs on and includes the disadvantages of a heat exchanger explained above.
- EP 0 043 879 A1 describes a cylinder Gas expansion element to convert from thermal to known motor energy.
- a piston slidably mounted.
- the cylinder points an upper injection opening for hot water and a controllable one lower water drain opening.
- the hot and cold water each have an injection opening with a spray dog pointing inside the pressure vessel Atomizer nozzle provided.
- the spray and atomizer nozzle causes a fine distribution of the sprayed warm or Cold water in the pressure vessel and thus a quick penetration of the gas.
- the separate Ensures injection openings with the assigned atomizing nozzles, that there are no residues when spraying cold water the hot water into the interior of the pressure vessel and Conversely, no residues of the cold water when injecting be introduced by hot water.
- At least the inner wall of the pressure vessel from a not Heat absorbing material or is with an insulation material coated.
- the liquid piston pump is expediently each with a Level sensor for an upper and a lower level the water inside the liquid piston pump. To when the upper level is reached, this is done under computer control Injecting the hot water into the pressure vessel, whereupon the gaseous medium in the pressure vessel expands and the level of the water inside the liquid piston pump sinks until the lower level is reached and the assigned level sensor spraying the cold water to contract the gaseous Medium signaled by computer.
- a check valve is used.
- the pressure vessel is advantageously funnel-shaped formed the swamp or in the direction of the water drain. This shape favors rapid drainage of the hot or cold water sprayed down.
- An essentially cylindrical to spherical pressure vessel 1 according to FIG. 1 has an injection opening on its upper side 2, one directed into the interior of the pressure vessel Has spray and atomizer nozzle 3. Via assigned valves 4 can alternately hot water or in the pressure vessel 1 Cold water can be sprayed.
- the pressure vessel filled with a gas or a gas mixture 1 is in its wall with a displaceable piston 5 connected, the connection to an arrangement 9 for converting thermal energy, especially a hot water engine, manufactures.
- the pressure vessel 1 is funnel-shaped at its lower section 6 formed in a pressure vessel 1 after below swamp 7 merges with its lower one End has a controllable lower water drain opening 8.
- the pressure vessel 1 In order to heat the air or other gases of the pressure container 1, becomes hot water directly via the assigned valve 4 and the injection opening 2 via the spray nozzle 3 into the pressure vessel sprayed where there is gas to expand immediately largely permeated.
- the pressure vessel 1 is at least inside, otherwise insulated so that there is no heat in the material.
- the inner wall is water-repellent, around the water introduced after cooling quickly to derive down.
- the air warms up with the spraying of warm water, expands and performs on the sliding piston 5 work, which is a working cycle not shown 20 of the arrangement 9 for converting the thermal energy is fed.
- the warm water is sprayed so that the heat or cold brought in the water can spread directly in the container. This ensures a high clock frequency (approx. one cycle in one up to three seconds).
- the amount of water required for heating is very small. It is enough to heat 100 liters of air from 0 ° C to 100 ° C 9.1 kJ in 22 g of water. This is a useful work from 3.6 kJ available (approx. 40% efficiency when using Air).
- Valves 4 assigned, the one valve 4 via a connecting line 10 with a cooling device 11 for generation of the cold water and the other valve 4 also via one Connection line 10 with a heating device 12 for generation of the hot water is coupled. Both the warm and the cold water enter a separate injection opening 2 each with associated spray and atomizing nozzle 3.
- the cooling device 11 and the heating device 12 are via a corresponding branching line 13 from one Pump 14 fed, the line 13 with an expansion tank 15 is connected.
- line 13 is immediate before the cooling device 11 and the heating device 12 a check valve 27, 26 is used, the check valves 27, 26 an outflow of the appropriately tempered Water from the cooling device 11 or the heating device 12 prevent.
- a check valve 25 between the pump 14 and an inlet 32 of the expansion tank 15 provided to the line 13.
- the expansion tank 15 protrudes an inlet valve 30 with a corresponding water supply in connection.
- the expansion tank 15 is a Pressure sensor 31 coupled to the pump 14.
- the pressure vessel 1 On the underside of the pressure vessel 1 according to FIG. 2 is one arranged with water 16 filled liquid piston pump 17, the on the input side with a water inlet 23 of the working circuit 20 coupled water outlet opening 8 of the pressure vessel 1 and on the output side with a water outlet 33 of the Working circuit 20 is connected.
- the water 16 in the Liquid piston pump 17 pressurized accordingly and the Level 18 reaches a lower end position by a level sensor 29 is monitored, the end of the spraying phase controls the hot water.
- the condensate or waste water accumulating in the pressure vessel reaches the working circuit via the liquid piston pump 17 20, which is coupled to the pump 14, which in turn by a corresponding control by the pressure sensor 31 of the Expansion tank 15, the waste water of the cooling device 11, the Heater 12 and the expansion tank 15 supplies.
- the valves 4, the level sensors, can be used to control the processes 28, 29 of the liquid piston pump 17, the pressure sensor 31 of the expansion tank 17 and / or the pump 14 with a computer, not shown, which is responsible for the injection processes, the level 18 and the pressure monitored and controls the previously listed components accordingly.
