Description

The invention relates to an ionic boiler, also called ionization or ion boiler.

The ionic boiler uses electricity as primary energy, like an electric boiler, with the difference that it has a particular heating body, using an ionic fluid allowing it to be heated: it works by implementing the principle of thermal agitation by friction. Heat is produced when the ions present in the fluid are set in motion by the alternation of the electric field. Their movements are the cause of a rise in temperature. This phenomenon is called the Joule effect.

• Un circuit primaire qui comporte un fluide caloporteur pouvant être une solution ionique comme de l'eau déminéralisée avec adjonction de sel, un corps de chauffe et un échangeur à plaques. Le fluide est monté en température dans le corps de chauffe grâce à la présence d'électrodes alimentée en électricité ;
• Deux circuits secondaires dans lesquels circule l'eau du système de chauffage (radiateurs par exemple), le second alimentant l'eau chaude sanitaire. En passant dans l'échangeur à plaques du circuit primaire, l'eau du circuit secondaire récupère la chaleur produite par effet Joule. Elle la transmet ensuite soit au système de chauffage avant de revenir dans la chaudière pour de nouveau être chauffée, soit au puisage sanitaire.

The ionic boiler works by implementing two hydraulic circuits:

• A primary circuit which comprises a heat transfer fluid which can be an ionic solution such as demineralized water with the addition of salt, a heating body and a plate heat exchanger. The fluid is brought up to temperature in the heating body thanks to the presence of electrodes supplied with electricity;
• Two secondary circuits in which the water of the heating system (radiators for example) circulates, the second supplying domestic hot water. By passing through the plate heat exchanger of the primary circuit, the water in the secondary circuit recovers the heat produced by the Joule effect. It then transmits it either to the heating system before returning to the boiler to be heated again, or to domestic hot water draw-off.

There are thus known ionic boilers which include a heating body comprising a fluid of ionic solution type and in which are positioned two electrodes, a plate heat exchanger, a primary circuit and a regulator.

The disadvantage of current ionic boilers is that they consume a lot of electricity to raise the temperature of the heating body. They are also bulky.

Moreover, they do not currently allow an implementation for a domestic hot water network and a heating network without an overheating mechanism.

The object of the invention is therefore to provide a more efficient ionized boiler and for this purpose relates, firstly, to a heating body for ionic boiler, said body comprising an inlet opening to allow the entry of a fluid of ionic solution type and an outlet opening to allow the exit of said fluid, a cylinder head at least partially receiving at least two first ends of at least two conductive electrodes connected to one phase, said yoke being connected to neutral.

The heating body is remarkable in that it comprises at least one third conductive electrode, said at least three conductive electrodes defining a geometric shape in said heating body and in that it comprises at least one secondary type electrode connected to the neutral and positioned at the center of said geometric shape.

Thanks to the positioning of at least one neutral electrode substantially in the center of the geometric shape formed by the phase electrodes, the extent of the electric field lines generated by the electrodes in the ionic solution at l is increased by at least 10%. inside the heating body.

The figure 1 illustrates an ionic boiler according to a first embodiment of the invention: it comprises a primary circuit 1 in which a fluid circulates. In the context of an ionic boiler, the fluid is an ionic solution, that is to say a solution which contains ions.

In the example described here, the ionic solution contains Na + and Cl- ions. This solution was obtained by adding salt to demineralized water, which allows control of the conductivity of the fluid and therefore the power of the boiler.

For example, for 6 liters of demineralized water, 3 g of salt (NaCl) were added.

The primary circuit passes through various elements that the boiler comprises, including a CC heating body, in which the ionic solution (or fluid) is heated, a regulation controller A, an EP plate exchanger and a primary circulator 2.

The function of the regulator A is to recover various data transmitted by temperature probes and, thanks to the implementation of a computer program and other information relating to the safety of use of the device, used to define the starting and stopping of the boiler.

The temperature probes include a primary circuit outlet temperature probe 4, placed near the outlet of the heating body CC, and a primary circuit return temperature probe 5 placed at the outlet of the EP plate exchanger.

The EP plate heat exchanger is used to exchange the calories from the primary circuit to a secondary sanitary circuit.

The primary circulator 2 has the function of circulating the fluid in the primary circuit.

The ionic boiler according to the invention also comprises a reservoir 3 for filling the primary circuit with fluid, as well as a purge valve 6 of the primary circuit.

Fittings (not shown) are used to connect the boiler to a secondary circuit to ensure the temperature rise of a network of radiators R or to ensure the rise in temperature of the water contained in a water tank or to ensure the rise in temperature of a sanitary network S using in particular the tank (see figures 7 to 9 ).

Finally, an overheating thermostat 7 is connected to the primary circuit near the tank 3 and communicates with the controller A.

The automaton A will not be further described in the present document because it is not the subject of the present application and the person skilled in the art has at his disposal many models of automatons and of literature which he will be able to choose according to the functions he wishes to implement in the boiler and the type of boiler to be implemented.

Reference will now be made to the DC heater shown in more detail in figure 2 : it comprises a tank 8 of cylindrical shape, comprising a lateral heating body inlet 9, located laterally and in the lower part of the heating body CC when the latter is fixed in the boiler.

The heating body also comprises a heating body outlet 10: the outlet is coaxial with the tank 8 and it is located at the top of the heating body CC when the latter is fixed in the boiler.

The ionic solution enters the heating body through the inlet 9 and leaves the outlet 10 to circulate in the primary circuit 1.

To set in vibration and raise the temperature of the fluid, the heating body comprises three conductive electrodes 11 connected to a phase.

To do this, the tank 8 of the heating body CC is open in the lower part and comprises a closing yoke 12, receiving a first support 13 and connected to neutral.

The support 13 has three through openings each receiving three bakelite rings 14, each of the rings 14 being fixed by a bolt system 15 in a through opening and receiving a first end 111 of an electrode 11.

The electrodes 11 have second ends 112 which are received in a support 80 placed inside the reservoir 8, at its upper end in the vicinity of the outlet 10.

Two screws 16 fix the first support 13 to the lower end of the tank 8 and the cylinder head covers the lower end and the support 13.

According to the invention, the heating body comprises a fourth secondary electrode 17, connected to neutral. The figure 3 shows the arrangement of the four conductive electrodes 11 and secondary 17 (connected to neutral) in the heating body: three conductive electrodes 11 form an equilateral triangle and the fourth secondary electrode 17 is placed at the center of the equilateral triangle. In other words, the fourth secondary electrode is positioned at the center of the geometric shape formed by the conductive electrodes 11.

Thanks to this arrangement, the electric field emitted by the conductive electrodes 11 extends further into the tank 8 of the heating body CC, because the secondary electrode placed in the center attracts the field emitted by the conductive electrodes 11. However, the The extended electric field 20 is at the origin of the heating of the ionic solution. The more the electric field is extended, the more the heating body is efficient.

Thanks to this arrangement of the electrodes according to the invention, the performance of the heating body is increased by at least 10%.

• Une électrode secondaire 17 est positionnée au centre de la figure géométrique formée par les électrodes conductrices 11, et
• Trois autres électrodes secondaires 17 sont positionnées entre les électrodes conductrices et forment également un triangle équilatéral.

Another configuration of conductive electrodes 11 and secondary electrodes 17 connected to neutral is shown in figure 4 and is even more efficient: In the context of this embodiment, the heating body always comprises three conductive electrodes positioned so as to form an equilateral triangle and four secondary electrodes 17, among which:

• A secondary electrode 17 is positioned at the center of the geometric figure formed by the conductive electrodes 11, and
• Three other secondary electrodes 17 are positioned between the conductive electrodes and also form an equilateral triangle.

This embodiment shown in figure 4 Further expands the electric field generated by the conductive electrodes in the DC heater body and the performance of the DC heater increases substantially by about 50%.

The operating principle of the heating body is as follows: a single-phase or three-phase electric current is brought by the conductive electrodes 11 into the ionic solution. The ionic solution being itself conductive allows the passage of the current which induces the Joule effect: the charge carriers (the ions Na + and Cl- in our example) in movement interact with the molecules of the medium which then constitute a brake on their movement. shift. To transfer a predetermined quantity of electric current, it is therefore necessary to provide an additional power which will be dissipated during the interactions between the charge carriers and the molecules of the medium in the form of thermal energy. This energy is at the origin of the increase in temperature of the medium.

Such a situation can also be at the origin of another chemical reaction of the medium which must be avoided: the oxidation-reduction of the electrodes due to the application of a high voltage at the level of the electrodes.

To avoid this phenomenon, and in accordance with the invention, provision may be made to cover the electrodes with a conductive material, such as, for example, poly (3,4-ethylenedioxythiophene), known under the trade name PEDOT®.

PEDOT® - sometimes abbreviated with the acronym PEDT - is a p-type conductive polymer (electron accelerator) made up of 3, 4 - ethylenedioxythiophene or EDOT monomers.

It is an organic compound that is both conductive and transparent, rather stable (it can therefore be exposed to light without degrading too quickly), with a moderate forbidden bandwidth (which makes it possible to capture a wider range of lengths of light). 'wave), and a low redox potential, which makes it possible to integrate it into composite structures without triggering corrosion phenomena of other organic materials.

This coating forms a protective layer which allows electrical conduction while protecting the surface of the electrodes from the redox phenomenon.

To further increase the performance of the heating body, the invention provides for placing an element therein in the upper part, in the vicinity of the outlet 10 of the heating body.

This element is shown in figure 5 and 6 : it is a deflector element 18 whose outer shape 19 is cylindrical and complementary to that of the tank 8 of the heating body CC, to fit into and rest in the tank 8 of the heating body at its upper end .

Furthermore, the deflector element 18 has a cavity 21 in the form of a truncated cone in the center of which a central opening 22 is made. The central opening 22 comes in line with the outlet opening 10 of the tank 8 of the heating body CC when the deflector element 18 is placed in the tank.

This deflector element 18 makes it possible to create a funnel around the outlet 10 of the tank of the heating body. Also, the right angle usually formed by the upper wall 23 and the side wall 24 of the heating body is then erased, and the heated ionic solution no longer rushes into this angle: it is oriented directly towards the outlet of the tank 8 .

The ionic solution heated by the heating body is then better guided towards the outlet of the heating body and the performance of the heating body is then further optimized.

Note that the truncated cone cavity 21 comprises housings 25 for receiving second ends 112 of said conductive electrodes 11 and possibly secondary 17 and maintaining them in a direction parallel to a central axis Z of said heating body CC.

The cavity has a surface which forms an angle α of approximately 120 ° with a direction parallel to the axis of the heating body CC.

The deflector element 18 replaces the support 80 in the example shown in figure 2 .

Finally, we note that the deflector element 18 comprises, in its opening 22 a centering piece 26 which is perforated and which has at its center a ring 27 capable of receiving the second end 112 of the neutral electrode 17 positioned at the center of the geometric shape formed by the conductive electrodes 11.

Thus, the centering piece 26 maintains the neutral secondary electrode 17 in the central axis of the heating body CC.

Thus produced, the heating body according to the invention allows a better distribution of the electric field produced by the conductive electrodes in the solution. ionic, and ensures a good distribution of the heated ionic solution towards the outlet opening 10 of the heating body: it is thus more efficient than the heating bodies of ionic boilers currently on the market.

Reference will now be made to an improved boiler according to the invention which has been shown schematically on the drawings. figures 7 to 9 by being implemented in installations also in accordance with the invention.

• à chauffer de l'eau sanitaire sensiblement de 10°C à sensiblement 60°C en utilisant un système de chauffe hybride. Un premier palier de température va atteindre sensiblement 45°C en mélangeant de l'eau froide (10°C) à l'eau d'un ballon (sensiblement 80°C). Puis, le second palier (60°C) est atteint par l'échange de chaleur du circuit primaire à l'eau sanitaire par l'échangeur EP, et
• à alimenter en fluide caloporteur un réseau de radiateurs R (chauffage) via le circuit secondaire.

In the context of these examples, the boiler according to the invention serves both:

• heating domestic water from substantially 10 ° C to substantially 60 ° C using a hybrid heating system. A first temperature level will reach approximately 45 ° C by mixing cold water (10 ° C) with water from a balloon (approximately 80 ° C). Then, the second level (60 ° C) is reached by the exchange of heat from the primary circuit to the domestic water by the EP exchanger, and
• supplying heat transfer fluid to a network of radiators R (heating) via the secondary circuit.

In this example, the boiler according to the invention comprises a second tank B, the capacity of which is approximately 50 L.

The boiler also includes a second exchanger ER (simply called a radiator exchanger) making it possible to adjust the temperature of the heat transfer fluid circulating in the heating system (radiators for example).

We note, on the figure 7 , that the primary circuit comprises, at the output T1 of the heating body, an atmospheric pressure control device CP.

The small capacity tank B is positioned at the outlet of the plate heat exchanger EP and an all-or-nothing valve VTOR is positioned at the outlet of the plate heat exchanger, upstream of the tank B.

In this way, all the power can pass either through the EP plate heat exchanger, or be shared between the plate heat exchanger and the radiator heat exchanger.

Tank B is very important in this circuit because it will ensure the rise in domestic hot water temperature from 10 ° C to 60 ° C: the domestic hot water tank is located in branch T5 and supplies in hot water the heat exchanger EP and thus the sanitary circuit S.

The water contained in tank B is heated to 80 ° C. either by an external plate exchanger (not illustrated) or by its own exchanger which is internal to the tank (outlet T7).

On section T8 of the sanitary network, cold water circulates at around 10 ° C. A DB flowmeter illustrates this cold water inlet.

A mixer M1 is used to mix the hot water at 80 ° C leaving tank B with cold sanitary water to obtain water at 45 ° C in section T5 which brings the water back to the EP plate exchanger. It is thus possible to raise domestic hot water from 45 ° C to 60 ° C by means of the boiler because this allows the boiler to be used only for drawing, which reduces electricity consumption.

On the other part of the network which ensures the rise in temperature of the heating network R, when the tank B has been recharged and we are out of sanitary draw, the majority of the calories then pass into the radiator exchanger ER. The temperature is then controlled by a set of flow rates between the accelerators (or pump) P1 and P2. The hot water circuit passes through section T3 to supply the various equipment.

The cooled water returns to the radiator exchanger ER via section T4 thanks to the presence of a pump P2. An VE expansion vessel is also provided on section T4 for reasons of safety and proper operation of the R heating network.

Finally, section T2 equipped with a pump P1 completes the network at the inlet of the heating body CC to ensure good circulation of fluids.

Reference will now be made to the installation shown in figure 8 . In this installation, the all-or-nothing valve VTOR is placed at the outlet of the radiator heat exchanger ER and at the inlet of tank B.

According to this installation, the tank B is separated from the EP plate exchangers and ER radiator exchangers so that each can work at its nominal value.

Balloon B is instructed to work at 80 ° C while the rest works at 65 ° C.

In T6, the domestic hot water outlet is always 60 ° C.

In T8, the domestic cold water always arrives at the mixing valve at 10 ° C.

In T5, the hot water always arrives at 45 ° C at the plate heat exchanger.

The VTOR valve is used either to recharge tank B at 80 ° C or to supply the EP sanitary exchangers and ER radiators.

The installation shown in figure 9 is still different: instead of providing an all-or-nothing VTOR valve, two sections T9 and T10 of the circuit are provided at the outlet of the atmospheric pressure control device CP, one (T9) in the direction of the plate heat exchanger EP and the other (T10) in the direction of tank B.

A pump P3 is provided on section T10 and controls tank B.

Another pump P4 is provided on the section T9 and controls the plate heat exchangers EP and radiator ER which operate at substantially the same temperature.

T1 connects the output of the CC heater to the atmospheric pressure control device.

In this installation, there is no longer a pump in section T2 which connects the inlet of the heating body CC to the radiator exchanger ER.

• T3 et T4 relient l'échangeur à radiateurs ER au réseau de chauffage R, T3 pour le fluide chaud et T4 pour le fluide refroidi.
• T5 relie le mitigeur M1 à l'échangeur à plaques EP en amenant le fluide à 45 °C.
• T6 relie l'échangeur à plaques EP au réseau sanitaire S (eau chaude à 60°C)
• T7 relie le ballon B au mitigeur M1 en apportant une eau à 80°C.
• T8 relie le réseau sanitaire au mitigeur M1 (eau froide à 10°C)

Sections T3 to T8 are also the same as those of the two previous installations, namely:

• T3 and T4 connect the radiator exchanger ER to the heating network R, T3 for the hot fluid and T4 for the cooled fluid.
• T5 connects the mixing valve M1 to the EP plate heat exchanger, bringing the fluid to 45 ° C.
• T6 connects the EP plate exchanger to the S sanitary network (hot water at 60 ° C)
• T7 connects tank B to mixer M1, supplying water at 80 ° C.
• T8 connects the sanitary network to mixer M1 (cold water at 10 ° C)

This installation makes it possible to carry out a priming and a setpoint temperature according to the many cases necessary for the operation of the boiler in domestic hot water mode. It also makes it possible to replace the VTOR all-or-nothing valve, which is less reliable than a pump (in addition, the pumps can be controlled in flow).

It will be understood from the foregoing how the invention enables energy savings to be achieved, on the one hand thanks to the optimized design of the heating body and on the other hand to the implementation of a hybrid system with a balloon. of hot water B and the heating body to limit energy losses when setting up the boiler.

It should be understood that the invention is not limited to the embodiment which has been specifically described or shown in the figures, and that it extends to the implementation of any equivalent means.
