Description

TECHNICAL FIELD

[0001] The present invention is an innovative system for the heating of liquids, in particular for the production of domestic hot water and / or for heating, for domestic and / or industrial use.

[0002] More precisely, the object of the present invention is an innovative system for the heating of liquids based on the so-called "cavitation principle" with high efficiency and energy performance.

[0003] The present invention therefore belongs to the field of devices and systems for heating fluids, and in particular for heating liquids.

[0004] More precisely, the present invention applies in the field of devices that use rotating elements to generate heat in the liquids that pass through them, such as the so-called "hydrosonic pump" shown schematically in the example in Figure 1 , also known as "hydrothermal turbine system". BACKGROUND

[0005] As is known, the "hydrosonic pump" 2 for the heating of liquids was conceived and industrially developed in the late 1980s and early 1990s.

[0006] To this end, the aforementioned pump 2, which can be crossed by the liquid to be heated (and substantially water), comprises a perforated cylindrical "rotor" 23 (i.e. equipped with a plurality of cavities 231) assembled with a rotating shaft 24, and a "stator" 22 inside the rotor 23 mentioned, which is able to rotate at high speed driven by an electric motor 21 (for example three-phase and powered indifferently by electricity, solar, wind, pneumatic energy, etc.), which is connected with the shaft 24 and works together with known procedures.

[0007] The stator 22 is also a cylinder, which comprises a curled inner surface and a pair of metal discs / coverings 25 and 26 (from now on called "end plates" or "closure flanges" 25, 26) for hermetically closing its ends.

[0008] The rotor 23 and the stator 22, which constitute the so-called "turbine" 20 of the hydrosonic pump 2, are mounted coaxially. They have specific dimensions and diameters, so that the gap or interspace between them can be filled and crossed by the liquid to be heated (more precisely, the gap between the inner curled surface of the stator and the outer surface of the rotor).

[0009] A specific piping system connects the aforementioned hydrosonic pump 2 to the primary circuit 3, and in particular to at least one of its liquid reservoirs 30 for the production of domestic hot water, and / or to the secondary circuit 4, which comprises, for example, a heat exchange unit to heat rooms (see Figure 2 ).

[0010] This is also useful because the mentioned liquid reservoir 30 can be implemented to the level of the heat exchange unit, for example a plate unit or a coil unit.

[0011] Since the characteristics and the operating process of said hydro-acoustic wave pump 2 are known to the person skilled in the art, we will not describe them in detail, we will instead refer to the document US5188090A for further details.

[0012] KR20110032112A is a prior art document which discloses a system for heating water based on a cavitation turbine for domestic purposes.

[0013] However, it is necessary to point out in this context that these machines heat the liquid mainly through the cavitation effect. As is known, this effect is based on the generation of areas or bubbles in the liquid which expand due to the pressure variations; during this process, they release energy and, precisely, heat, which is absorbed by the liquid itself.

[0014] In other words, the heating of said hydro-acoustic wave pump is enabled due to the very high turbulence of the liquid caused by the specific geometric and structural configuration of the rotor 23 and its cooperation with the stator 22.

[0015] Experimental findings have shown that, thanks to this turbulence, these hydro-acoustic wave pumps 2 are able to achieve a much higher efficiency than traditional heat generators, usually used for the production of domestic hot water and / or for space heating (for example, ordinary domestic boilers).

[0016] However, the performances obtained so far have not proved to be completely satisfactory, also due to the very complex architecture of the hydro-acoustic wave pump 2 and to the problems related thereto; this defect has had a negative impact on its industrialization and commercialization.

[0017] For example, it has been emphasized that such hydro-acoustic wave pumps 2 for the production of domestic hot water and / or for space heating reach their maximum efficiency only if the temperature of the input liquid within the mentioned pump 2 does not differ "too much" from the temperature of the same liquid output from said pump 2 (with respect to the amount / flow rate of the circulating liquid); in fact, in this condition, the maximization of the cavitation effect is ensured.

[0018] To this end, as widely described by using the previous Italian patent application n. 10201800006358 (further details can be referred to that patent application), a specific activation and management mode of the hydro-acoustic wave pump 2 is considered and implemented, with the main purpose of optimizing and maximizing the efficiency and performance. This mode has a series of liquid heating phases, each combined with the other, during the initial process of activation of the hydro-acoustic wave pump 2, i.e. before reaching full operation; in particular, during the first phase, the hydro-acoustic wave pump 2 is activated to first quickly heat the liquid loaded therein, in addition, during this phase, the circulation towards the primary circuit 3 is locked, and the subsequent phases are the passage through the hydro-acoustic wave pump 2 and the reservoir 30 of the primary circuit 3, once the liquid has reached the desired temperature (see Figure 2

[0019] These phases are repeated until the gradient between the inlet and outlet temperatures of the liquid of the hydro-acoustic wave pump 2 described above matches or deviates from the optimal value that ensures the best and maximum energy performance. (As an alternative to this procedure of activating and managing the hydro-acoustic wave pump with repeated interruptions of the liquid flow, it would be possible to heat the liquid circulating in the hydro-acoustic wave pump 2 and in the reservoir 30 of the primary circuit 3, but only as a whole and much more slowly, without any benefit and with lower efficiency).

[0020] From what has just been said, it is clear the complexity of managing the hydro-acoustic wave pump 2 of the prior art, especially during the initial and temporary phases of the procedure, and the difficulties related to the connection and cooperation with the primary and secondary circuits.

[0021] The achievement and maintenance of the optimal operating conditions require long times to be implemented, which also cause considerable delays in achieving the full availability and operability of the liquid heating system for sanitary use and / or for indoor heating.

[0022] The results can also reflect an increase in the operating costs of the system itself. SUMMARY

[0023] The aim of the present invention is to eliminate the drawbacks of the known art listed above by means of an innovative system for the heating of liquids and preferably for the production of domestic hot water and / or for space heating, which is able to achieve and ensure maximum efficiency and energy performance quickly and in a simple and reliable manner.

[0024] These and other aims are achieved according to the present invention, whose characteristics are listed in the attached independent claim 1. BRIEF DESCRIPTION OF DRAWINGS

[0031] To describe the elements of the device according to the application, it is useful to refer to the attached drawings. It should be noted that any dimensional and spatial terms (such as "lower", "upper", "right", "left", etc.) refer to the correct setting of the application as indicated in the drawings and do not necessarily correspond to the setting of the application during the working period, unless otherwise stated.

[0032] The drawings shown on the attached drawings are not necessarily drawn to scale in order to emphasize certain features rather than others.

[0033] Furthermore, the elements shown on the attached drawings can not be considered all essential to the application; the essential elements will be explicitly indicated.

[0034] Furthermore, similar reference numerals will correspond to components of the system of the application that have already been described with reference to the prior art.

[0035] As Figure 3 clearly shown in the attached drawings, 1 represents a system for the heating of a liquid and preferably for the production of domestic hot water and / or for space heating.

[0036] According to the application, Figure 1 a system is specifically shown:

[0037] - the hydraulic acoustic wave pump 2 (for further details, refer again to the prior application No. 10201800006358 already cited) identical to the one described above of the prior art, with the ability to exploit the cavitation phenomenon and to carry out the heating of a liquid, the mentioned hydraulic acoustic wave pump 2 having (see also Figure 1) at least one "cavitation" turbine 20 and an electric motor 21 able to power and operate said turbine 20;

[0038] - an "optimizer" 5, coupled to the hydrosonic pump 2 and downstream of the hydrosonic pump 2, which will be described in detail immediately below with regard to the technical functional characteristics and related advantages; the optimizer 5 can cooperate at least with the primary circuit 3 in order to move the thermal energy generated by the hydrosonic pump 2;

[0039] - the above-mentioned "primary" circuit 3, which has at least one tank 30 for storing the liquid heated by the hydrosonic pump 2 and circulated through the optimizer 5;

[0040] - the above-mentioned "primary" circuit 3, which has a heat exchanger unit 45, as an alternative to or not as an alternative to the tank 30, which exchanges the heat of the hot liquid coming from the hydrosonic pump 2 and circulated through the optimizer 5.

[0041] The system 1 of the present application can further comprise a secondary circuit 4 (see Figure 3 ) to dissipate the heat generated in the hydrosonic pump 2 and transferred to the liquid flowing therethrough, and transferred to the secondary circuit 4, which works together with and / or is connected to the primary circuit 3.

[0042] Hereinafter, both the hydrosonic pump 2 and the optimizer 5 can also be referred to as "high-efficiency cavitation boiler".

[0043] The above-mentioned cavitation boiler can further comprise an expansion bottle (not shown in the drawings), which is well known to have the function of containing the volume increase and the resulting pressure variation of the liquid heating, which also avoids pressure fluctuations and water hammers, which would otherwise be absorbed by the system and cause potential damage.

[0044] The reciprocal connection between the pump 2 and the optimizer 5, which constitutes the high-efficiency cavitation boiler, is ensured by respective flow pipes 51 and return pipes 50, as shown in Figure 3 , which are both named "internal circuit" 501, for more details see the attached Figure 4 .

[0045] It is also necessary to specify that, for reasons that will be further clarified in the following, there is also a flow pipe 31 and a return pipe 32 between the optimizer 5 and the tank 30 of the primary circuit 3; in particular, the flow pipe 31 from the optimizer 5 to the tank 30 and the return pipe 32, which carries the liquid from the tank 30 back to the optimizer 5, in the opposite direction; or the flow pipe 31 from the optimizer 5 to the heat exchanger 45 and the return pipe 32, which carries the liquid from the heat exchanger 45 back to the optimizer 5, in the opposite direction.

[0046] The circulation of the liquid between the optimiser 5 and the primary circuit 3 can be ensured by at least one first pump 33, and its flow rate is regulated by at least one suitable electromagnetic valve 34.

[0047] More precisely, the electromagnetic valve 34 described above is able to interrupt and / or re-establish the circulation of the liquid from the optimiser 5 towards the primary circuit 3 described above, as a function of the temperature detected, and is able to set its circulation temperature.

[0048] To this end, the electromagnetic valve 34 is coupled to a sensor and / or temperature probe 35, which corresponds to the hydraulic acoustic wave pump 2 within the internal circuit 501 and is placed along the outflow pipe 51 from the optimiser 5.

[0049] As Figure 4 clearly shown in the accompanying drawings, at least one electromagnetic valve 34 is placed along the flow line 31 of the primary circuit 3.

[0050] Optionally, a second circulation pump can also be provided within the cavitation boiler, which can facilitate the flow of the liquid to be heated between its cavitation turbine 20 and the optimiser 5.

[0051] As described below, the circulation within the cavitation boiler can be carried out directly by natural flow, without the aid of mechanical propulsion means.

[0052] In both cases, the flow interrupter 8 (see Figure 3 and Figure 4 ), also known as a cut-off valve, similar to the cut-off valve in the prior art indicated by reference numeral 36 in Figure 2 allows the regulation of the flow and in particular of the flow rate.

[0053] The secondary circuit 4 has the function of dissipating the heat generated by the high-efficiency cavitation boiler, which is constituted by:

[0054] - at least one heat exchanger 40 for dissipation; the heat exchanger 40 has at least one radiator 40 for space heating; and / or

[0055] - one or more heat exchangers, for example coil heat exchangers, inserted within the reservoir 30 of the primary circuit 3; and / or

[0056] - any means for direct supply of the liquid.

[0057] At least one circulation pump, which ensures the flow of the liquid described above within the secondary circuit 4.

[0058] It has been partially explained that the cavitation boiler of the present application achieves its maximum energetic performance and efficiency when the temperature of the liquid entering the turbine 20 of the hydro-acoustic wave pump 2 has a value "not far" from the temperature of the same liquid when it is subjected to heating and exits the hydro-acoustic wave pump 2 (with reference to the circulation flow rate). In this case, the hydro-acoustic wave pump 2 does not suffer any thermal "shock" and therefore any possible slowdown or adverse condition of the liquid heating is avoided.

[0059] In other words, it has been observed that the cavitation boiler of the present application reaches the maximum operating efficiency when the difference (or gradient) between the inlet temperature and the outlet temperature of the liquid in / from the turbine 20 of the hydro-acoustic wave pump 2 remains constant and equal to a value from now on defined as AT 理想 .

[0060] To this end (i.e. in order to manage the flow of the circulating liquid and keep the above-mentioned AT 理想 ), as an alternative to the reservoir 30 of the primary circuit 3 of the prior art, it is envisaged to use a specific and dedicated inertial accumulation of the liquid treated in the hydro-acoustic wave pump 2, which has a reduced volume and is able to avoid the leakage of the heat already stored therein and is able to withstand a rather high pressure (in fact, during the working condition, the liquid can be at high temperature and therefore in a vapour state if it is not circulated at a suitable pressure).

[0061] According to the present application, the above-mentioned inertial reservoir is therefore a "small" reservoir, which corresponds to the above-mentioned optimiser 5.

[0062] In fact, the optimiser 5 is arranged to allow the cavitation boiler (and in particular its cavitation turbine 20) to exchange heat with the primary circuit 3 and / or with the secondary circuit 4, without significantly varying the above-mentioned gradient AT 理想 , which remains constant.

[0063] As highlighted in the foregoing, AT 理想 is the gradient that ensures the maximum efficiency of the hydro-acoustic wave pump 2, which can advantageously be chosen as a fixed and optimal threshold, which can be set by a probe or thermostat.

[0064] Experiments have shown that the above-mentioned AT 理想 varies as a function of at least the delivery temperature of the hydro-acoustic wave pump 2 (or, equivalently, of the outlet temperature of its turbine 20), that is, it can increase as a function of an increase of said temperature.

[0065] On the other hand, by AT 优化器 is indicated the temperature difference between the inlet liquid and the outlet liquid of the optimiser 5, it is desirable that this gradient never falls below the aforesaid threshold AT 理想The performance of the boiler can thus be maximized.

[0066] To this end, the solenoid valve 34 (or technically equivalent device) "manages" the flow of liquid between the optimizer 5 and the primary circuit 3 as follows:

[0067] - interrupts it when ΔΤ 优化器 drops below said ΔΤ 理想 , and subsequently

[0068] - allows further rapid heating of the liquid circulating between the water pump 2 and the optimizer 5, at least until the optimal ΔΤ 优化器 is restored.

[0069] In other words, the optimizer 5 described above works so as to maintain ΔΤ 优化器 equal to ΔΤ 理想 under operating conditions.

[0070] This operating mode of the system 1 of the application will be discussed immediately in a more specific and detailed manner.

[0071] Here, it is sufficient to repeat that the optimizer 5 described above behaves substantially as a certain "thermal flywheel", in that it allows the liquid heated by the hydro-acoustic pump 2 to transfer part of its heat to the primary circuit 3 and / or to the secondary circuit 4, without any substantial variation or change in ΔΤ 优化器 .

[0072] In other words, the optimizer 5 described above is a device capable of working between a first operating temperature and a second operating temperature, in which:

[0073] - the first temperature is the temperature at which the solenoid valve 34 interrupts the circulation of the liquid towards the primary circuit 3 and / or the secondary circuit 4, so as to allow the flow to circulate only between the optimizer 5 and the hydro-acoustic pump 2 so as to restore the maximum efficiency of the boiler, and

[0074] - the second temperature is the temperature at which the optimizer 5 is allowed to reopen and connect towards said primary circuit 3 and / or secondary circuit 4 once said maximum efficiency is guaranteed.

[0075] In general, the first operating temperature is lower than the second operating temperature, in fact their difference defines the ΔΤ 优化器 described above.

[0076] According to the application, the optimizer 5 described above has a tank 52 with reduced volume, but resistant to high pressure so as to allow rapid or sudden heating.

[0077] More precisely, the aforementioned optimizer 5 has a capacity that is intermediate between a traditional reservoir for liquids (generally, tanks with different volumes, and they vary from 20 to 30 liters, and they do not operate at high operating pressures) and a hydraulic compensator (known to those skilled in the art, and in which the maximum volume is between 2-3 liters, but which withstands high operating pressures).

[0078] The optimizer 5 is thermally insulated in order to reduce the inevitable heat losses of the liquid treated and contained therein; in other words, the thermal insulation is able to reduce the heat losses even when the hydromechanical acoustic wave pump 2 is stopped, which maintains the high temperature inside the tank 52 even for many consecutive hours.

[0079] In this regard, by way of example only and without any limitation, the tank 52 of the aforementioned optimizer 5 has a volume of between 7 and 15 liters, and it is able to withstand pressures even exceeding 20 bar.

[0080] As Figure 4 As is clear from the diagram in the drawing, ideally the tank 52 has two inlets in the aforementioned pipes 50, 32 for the supply and return, and in particular said pipes 50, 32 come from the hydromechanical acoustic wave pump 2 and from the primary circuit 3; and the tank 52 has two outlets in the pipes 31, 51 for the supply and return, and in particular said pipes 31, 51 come from the primary circuit 3 and from the same hydromechanical acoustic wave pump 2.

[0081] Furthermore, Figure 3 The reference number 53 in the drawing identifies a typical and automatic venting valve (also known as wild card valve) from the supply 52 of the optimizer 5.

[0082] The hydromechanical acoustic wave pump 2, its electric motor 21 and the optimizer 5 can be arranged placed side by side, or vertically stacked in several layers on a frame (also known as chassis or shell of the tank boiler).

[0083] The aforementioned chassis can also be equipped with a control panel and screen for setting, as well as managing and displaying other operating and functional parameters of the system 1 of the application and of the related boiler.

[0084] Once the description of the liquid heating system 1 has been completed in all its technical and constructive aspects, we can now proceed and describe in detail the optimization procedure of the relatively high-efficiency cavitation boiler, which is possible thanks to the presence of at least the aforementioned optimizer 5.

[0085] Without any purpose of limitation, it has been observed experimentally that the optimization of the performance of the cavitation boiler can be achieved when the following operating and / or temporary conditions are met:

[0086] - the cavitation turbine 20 of the hydromagnetic acoustic wave pump 2 processes a liquid flow / circulation flow rate of between 200 and 300 litres / hour, which can be set and kept constant by means of the aforementioned bleed valve and which is susceptible to "passing through" and flowing without interruption by the optimiser 5 until the backflow temperature, preferably between 100 / 110°C, is reached inside the turbine,

[0087] - once the backflow temperature has been reached, the solenoid valve 34, connected to at least one thermostat probe 35, starts the liquid circulation between the optimiser 5 and the primary circuit 3 and, in particular, towards the relative tank 30, in which the heated liquid starts to gradually replace the colder liquid already inside it and, in fact, it returns to the optimiser 5 through the aforementioned backflow pipe 31.

[0088] This circulation between the tank 30 of the primary circuit 3 and the optimiser 5 inevitably causes a lower temperature inside the optimiser 5 itself, up to far below the aforementioned turbine backflow temperature of 100°C.

[0089] Through experimental observations, it has been observed that this circulation causes the backflow temperature to drop to a maximum of 90-97°C; therefore, under these conditions, the thermostat sensor closes the solenoid valve 34 previously opened.

[0090] Once the aforementioned ideal backflow temperature of 100° has been reached again and due to the continuous flow of heated liquid between the optimiser 5 and the hydromagnetic acoustic wave pump 2, the solenoid valve 34 starts the circulation and circulation towards the primary circuit 3 again, whereby the heat exchange process is repeated.

[0091] The secondary circuit 4 for the dissipation of heat (as mentioned previously, the aforementioned radiator and / or exchanger inside the tank 30, etc.) can exchange heat with the tank 30, which, once the correct temperature of the room "provided" by it has been reached, will control the closure or standby of the high-efficiency cavitation boiler by means of a dedicated and specific thermostat, until the gradient ΔT 优化器 and ΔT 理想 have substantially the same value.

[0092] Since ΔT 优化器保持 is stable and equal to ΔT 理想 , the solution 1 of the present application is able to immediately supply heat in the event that the secondary circuit requires more heat.

[0093] Therefore, the circulation between the optimiser 5 and the hydromagnetic acoustic wave pump 2 is never interrupted and the hydromagnetic acoustic wave pump is not subjected to any thermal shock; therefore, the heating of the liquid that can be used for sanitary purposes and / or for the heating of the room has a gradient ΔT 理想 and a substantially stable temperature at the inlet and outlet from / to the aforementioned hydromagnetic acoustic wave pump 2, therefore the ideal temperature is:

[0094] - equal to about 30°C; as already checked, this temperature refers to an outlet / delivery temperature of about 130°C and a backflow temperature in the turbine 20 of about 100°C;

[0095] - equal to about 35°C, this temperature refers to an outlet / delivery temperature of about 145°C and a backflow temperature in the turbine 20 of about 110°C.

[0096] In the practical implementation of the present application, various modifications and further variations are contemplated, as they all belong to the same inventive concept; in fact, all the several components and details described above can also be replaced by technically equivalent elements.

[0097] In summary, the system for the heating of liquids, in particular for the production of domestic hot water and / or for heating, as well as the related method for optimizing its energy performance and efficiency, has achieved the objectives; in particular, it has been possible to ensure high efficiency and performance by using mechanical components with the following characteristics: they are simple, economical and highly reliable in construction; all this in a quick, easy and reliable way.

[0098] Moreover, the system 1 of the present application is suitable for many other purposes; in fact, in addition to its application for the production of domestic hot water for civil or industrial use and for space heating, it can also be used (as a non-exhaustive example) for climate conditioning, for hot water supply in household appliances (for example washing machines and dishwashers), for the supply and heat pump of industrial machines (for example thermal printers and the like), etc.
