Definitions

  • the present invention relates to a sanitary storage water heater. It finds its application in the field of installations, in particular domestic, for the production of hot water.
  • the water heater in question is connectable to a cold water supply network.
  • the storage water heaters allow the storage of a determined quantity of water at a temperature higher than a cold water inlet temperature for immediate delivery.
  • water heaters generally consist of a single tank, most often of cylindrical shape and in which a resistive electrical device for heating water is immersed.
  • a storage water heater comprising two identical tanks placed so as to form a series circuit and each having an individual heating device making it possible, according to this prior art, to heat the water in the most downstream tank following the circuit adopted by water at a temperature lower than the tank preceding it.
  • These two tanks are placed in a rectangular parallelepiped envelope so as to give this system a flattened external shape.
  • a drawback of such a configuration is that the multiplication of cylindrical tanks in parallel increases the heat exchange surface outside the walls of the tanks so that, even if such devices have an advantage in terms of aesthetics and '' external dimensions, they are significantly penalized by their lack of thermal efficiency in comparison with traditional cylindrical single-tank water heaters.
  • a potential objective of the invention is to improve the thermal efficiency of water heaters with several cylindrical tanks.
  • this water heater is such that the longitudinal axes of the tanks are included in a median plane with a thickness dimension of the envelope, and in that the downstream tank has a diameter less than that of the upstream tank .
  • the flattened shape of the water heater is preserved but the insulation of the downstream tank is increased because the amount of insulation surrounding it is higher than for the other tanks.
  • the internal design is therefore heterogeneous in shape in this water heater but, however, the external form remains flat.
  • the downstream tank is configured so that the temperature within it is higher or possibly equal to that of the other tanks; despite this, the heat loss from the tank downstream are not increased relative to the other tanks because the insulation is better. This allows, at the outlet of the water heater, to have a more efficient final heating.
  • the arrangement of the invention ensures a significant improvement in efficiency for a flat water heater, close or even identical to that of a cylindrical external shape water heater.
  • This arrangement allows the temperatures of the tanks to be advantageously differentiated; a higher final heating can be assigned in the downstream tank, the previous tanks providing preheating; in this context, if the heating power in the downstream tank authorizes it, there may occur at this location, before the outlet, a strong gradient heating, possibly almost instantaneous.
  • the water heater then offers great flexibility of use. For example, these functional arrangements can be used to adapt the operation of the water heater to situations of use that can vary widely.
  • Another aspect of the invention relates to a method for regulating the temperature of a multi-tank water heater.
  • the present invention comprises a plurality of tanks, with a downstream tank 1 and at least one upstream tank 2.
  • the example of the figure 1 illustrated a water heater provided with three tanks, with two upstream tanks 2. This example is not limiting and only two tanks may be present, or more than three tanks.
  • the cross section of the tanks 1, 2 relative to a longitudinal direction marked Z is circular so as to give the tanks 1, 2 a cylindrical geometric shape elongated along a longitudinal axis parallel to the longitudinal direction Z of the figure 1 . It is understood that this cylindrical geometry delimits, inside, a volume for receiving water in each tank.
  • Each tank is also equipped with a bottom 4 at one end of the cylindrical shape and with an upper wall so as to close the water storage volume.
  • the thickness of insulation around the downstream tank 1 is at least as great between its outer wall and the side wall 18 of the casing 15 and between its outer wall and the bottom and / or top wall of the envelope 15, that between its wall and the main walls 16 of the envelope 15.
  • the downstream tank 1 has a diameter less than that of at least one upstream tank 2.
  • the upstream tanks have the same diameter and the downstream tank 1 has a diameter less than the latter.
  • the upstream tanks can have decreasing diameters and greater than that of the downstream tank, in the downstream direction along the circuit taken by the water.
  • the diameter of the downstream tank can be between 100 and 180 mm and is for example between 120 and 160 mm and more preferably be 140 mm.
  • the diameter of at least one of the upstream tanks can be greater than that of the downstream tank by at least 20% and preferably at least 30% and preferably less than 50%.
  • the upstream tanks can have a diameter of 180 mm.
  • the representation of the figure 1 also provides an illustration of the path that water can follow between an inlet to an outlet of the water heater. More precisely, through the tanks, the water can circulate from an inlet 5 opening at the bottom 4 of a first upstream tank 2, traversing the upstream tank 2 in the longitudinal direction Z to reach, via a fluid connection 8 by example of tubular shape opening into the above-mentioned upstream tank 2 and into an upstream tank 2 which follows it, into the second upstream tank 2 so as to receive additional heating.
  • the fluidic connection is for example a conduit, such as a tube, connecting two zones, one of a first tank, the other of a next tank.
  • the connector extends along the longitudinal axis of the tanks so as to reinject the water leaving a upper end of a tank at the opposite end of the next tank so as to capture water at the hottest point of a tank and to reintroduce it at the coldest point of the next tank.
  • This principle can be renewed along the circuit, between all the tanks, and at the outlet, for the collection of water in the zone of higher temperature.
  • a fluid connection for example similar to the fluid connection, is arranged near the top of the intermediate upstream tank 2, to connect from said tank to the downstream tank 1.
  • the water thus enters the downstream tank 1 so as to be heated therein in a final manner until reaching an outlet 6 opening at the upper level of the downstream tank 1 and the lower end of which is visible in figure 2 , at the outlet of the water heater.
  • Any series / parallel configuration in the connection of the tanks is possible.
  • Certain connections or conduits can also be internal to the tanks, for example for outlet 6 which can extend into the tank to draw water at a height greater than that of its external mouth.
  • the casing 15 is configured to surround at least the tanks, but not necessarily all of the fluid communication connections between tanks or at the inlet / outlet of the plurality of tanks.
  • the water heater is advantageously positioned so that the longitudinal direction Z corresponding to the direction of the longitudinal axes of the tanks 2 and 1, is positioned along the vertical.
  • This provision is however not limiting and in particular the water heater can be oriented horizontally.
  • the water flowing through the tanks is brought to be heated preferably by electrical means. More specifically, it is advantageous to equip each tank with an electric heating device. In this way, the power supplied to each of the tanks can be individually regulated so as to control the level of heating of the water individually in the tanks.
  • the electric heating device fitted to each tank or at least one of them is of a resistive nature and for example comprises a resistance plunging directly or into a sheath into the interior volume of the tank considered.
  • the inductive heating device is, in the tanks considered, immersed in the cylindrical interior volume. It obeys an inductive operation, namely that an electrical energy is supplied to an inductor itself designed to generate a magnetic field such that an induced current is produced in a charge, in a magnetic material preferably metallic, the charge being configured to transmit energy in the form of heat to the water stored in the tank.
  • This energy transmission can be direct or indirect, for example with a thermally conductive element intermediate between the load and the water to be heated.
  • each tank is fitted with an inductor immersed in its internal volume, an example of which is more precisely visible in Figures 4 and 5 .
  • the inductor 20 comprises an elongated electrically conductive element, of oblong shape, and here in the shape of a closed contour.
  • the inductor 20 has electrical connections 23 allowing the access of an electric current to the inductor 20.
  • the inductor 20 is advantageously electrically isolated from its external environment, for example by an insulating lining. or any other coating or by a waterproof sheath surrounding it.
  • the inductor 20 travels a length between 30 and 80% of the length of the cylindrical portion of the tank which it equips.
  • the load 21 can be in two parts, in particular essentially symmetrical around a plane, and assembled together around the inductor 20, for example by studs 22.
  • the interior surface of the load 21 is thus kept at a distance from the inductor 20 but relatively close so as to generate in the load an induced current suitable for its heating to in turn heat the water.
  • the power supply of the inductor can be between 1000 and 3700 W, more preferably between 1500 and 2500 W.
  • the load 21 may have a plurality of holes.
  • the water can circulate between the load 21 and the inductor 20. This circulation obviously promotes the efficiency of the heating, allows a more dynamic circulation of the water and, advantageously, limits or even eliminates the formation of limestone due to proximity phenomena, in particular magnetic and vibratory, at the level of the charge.
  • the longitudinal axes of the tanks are parallel and placed in a plane itself corresponding to a plane parallel to one of the faces of the casing 15 of the water heater described in detail later.
  • This plane is preferably in the middle of the thickness dimension marked “X” of the envelope 19.
  • the electrical heating devices present in the tanks are preferably also oriented along a longitudinal axis, the longitudinal axes of the heating devices themselves being also aligned.
  • the three electric heating devices are linked, their axis being oriented in a median plane of the envelope like the longitudinal axes of the tanks.
  • Inductive technology preferably requires the use of a generator represented in a supply device 10 aux figures 1 and 2 .
  • the power supply device 10 may be contained in a box 11, and may include an electrical input connectable to an electricity network, for example to a domestic network.
  • the power supply device 10 provides the electrical conversion making it possible to generate an electrical signal adapted to the operation of the inductive electrical devices preferentially equipping the water heater.
  • the power supply device 10 can comprise an inverter system for reducing the frequency of the signal to be supplied. This type of device generally produces a significant amount of heat which generally requires a forced flow heatsink to cool it down.
  • an exchanger 12 is located in electrical conduction with the supply device 10 to recover at least a portion of the calories dissipated and comprises an exchange surface with a water circuit going from a connection of inlet 14 connectable for example to a domestic water network towards the inlet 5 of the upstream tank 2 of cold water inlet. It is understood that the water passing inside the exchanger 12 benefits from a first heating.
  • the tri-tank or generally multi-tank configuration of the invention present in an application of inductive heating the advantage of offering selective cooling of the supply device 10 at a tank in which the water is the coldest.
  • each of the tanks of the water heater of the invention is equipped with an inductive electric heating device.
  • a single supply device can be provided for all of these tank heating devices.
  • the supply device 10 alternately supplies each tank heating device, via switching means.
  • This switching can be controlled according to a temperature regulation of each tank (each tank can have at least one temperature sensor).
  • a switching instruction can be given so as to produce the generation of an inductive heating in one tank after the other.
  • the multi-tank configuration including the example of the figure 1 gives a tri-tank arrangement, there is covered with an envelope 15 for example corresponding to that of the figure 2 having a rectangular parallelepiped shape.
  • a rectangular parallelepiped shape is meant the fact that the outer surface of this part of the water heater has substantially two parallel and flat main faces 16 spaced apart by side walls 18, a bottom wall 17 and an upper wall. All of these faces and advantageously planar, which includes provisions comprising surface patterns, in particular for aesthetic purposes, or even rounded angles at the junction of the different walls.
  • the expression rectangular parallelepiped covers similar provisions capable of being substantially delimited in a rectangular parallelepiped shape.
  • the supply device included in the box 11 is outside the envelope 15.
  • the casing 15 constitutes the external appearance of the water heater of the invention at least for its hot water storage part. It also ensures the definition of an interior volume that can be filled with an insulating material 19 for example in the form of foam polymers advantageously taking all or part of the interstitial volume between the exterior surface of the tanks and the interior wall of the envelope 15 Preferably, the entire interstitial interior volume is filled with the insulator 19.
  • the heat losses at the level of the downstream tank are therefore more limited. It is advantageous to benefit from this increase in insulation for temperature regulation. More specifically, in a preferred embodiment, the temperature setpoint given to the downstream tank 1 is advantageously higher, at least in certain cycles of use, than the temperature of at least one of the upstream tanks 2. Thus, it is possible to obtain a water storage temperature in the downstream tank at a higher level while reducing the normally higher heat losses in this context. While the skilled person would have sought to optimize the volume of water stored, the present invention takes the opposite by choosing in this example a smaller diameter for the downstream tank which certainly limits the amount of water stored but allows with a high thermal efficiency, much higher terminal heating.
  • the setpoint temperature of the downstream tank can be 5 to 30 ° higher than the setpoint in the tank which precedes it with in particular a maximum temperature to be reached of 90 ° C last tank, with a safety margin so as not to boil, knowing that the other tanks are typically at 65 ° C, or 25 ° C more.
  • the electric heating devices equipping the tanks are identical so as to simplify the design of the water heater but also to ensure that the maximum heating power available at the level of the heating device equipping the downstream tank 1 is equivalent to that of other devices.
  • the interior volume of the downstream tank being smaller, it follows a more brutal heating of the water which can make it possible, in certain cases, to obtain an almost instantaneous additional heating during the delivery of hot water.
  • the supply device 10 is configured to supply the electrical device for heating the downstream tank when a delivery of water at the outlet 6 is carried out.
  • a flow detector can be used at the level of the water heater, and in particular at the level of outlet 6 for this purpose.
  • the supply device can be configured to switch periodically between the different tanks.
  • the supply device is configured to switch to another tank as soon as the set temperature assigned to the tank for which the electric heating device is active is reached.
  • the supply device then switches to the heating device fitted to the tank in which the current temperature is furthest from the set temperature which is assigned to it.
  • having 3 or more tanks gives modular heating. If we need little hot water, we will concentrate the heating on the last tank, and if more water is required we will heat more, the last and the penultimate, or even more, the 3 tanks .
  • the invention can also implement, in particular at the level of the supply device 10, a learning device so as to adapt the operation of the supply control according to the habits of the place in which the water heater is located.
  • the learning device can comprise a computer program product stored in a memory accessible by a processor and capable of taking into account as an operating parameter the average hours of hot water withdrawal at the level of the water heater.
  • This device can also take into account regulation of tariffs, in particular off-peak and peak hours.
  • the figure 6 presents an alternative for the construction of inductive devices. Indeed, the previous figures illustrated electrical heating devices inserted in the tanks. On the contrary, the figure 6 shows an inductive heating device operating from the outside of the tanks.
  • an inductor 20 equips a tank and is in the form of a winding covering all or part of the length of the cylindrical part of the equipped tank. This winding is, as previously, connected to the supply device 10.
  • At least part of the wall of the equipped tank is in this frame made of a magnetic material, preferably metallic, to form a charge in which an induced current will develop and provide by joule effect as previously a heating of the water. Conduction through the thickness of the wall of the tank will be used to transmit this heating to the water stored internally.
  • means are formed to keep the inductor 20 wound apart relative to the wall of the equipped tank.
  • an insulator 22 or any other holding element spaced between the load part and the inductor part can be formed.
  • the wall of the equipped tank is entirely metallic depending on its thickness and is then covered with an insulator in the form of a sheet traversing the entire surface intended to be covered with the inductor winding. This arrangement makes it possible to equip tank diameters which can be relatively small without penalizing the storage volume of the tanks.
  • one or more of the tanks can be equipped with an immersive inductive device while another part of the tanks can be equipped with an inductive device from the outside.
  • the invention can combine at least one inductive device with at least one resistive tank heating device.
  • one or more of the tanks can be equipped with a plurality of inductors.
  • a tank can for example comprise two inductors each traversing a part of the length of the tank in a plunging manner.
  • a tank may have a plurality of windings on its outer wall.
  • a tank can be equipped with one or more exterior winding systems and one or more interior plunging systems.
  • water is introduced via the inlet connector 14 to the inlet 5 of the first upstream tank 2. Before even reaching it or at this level it has already benefited from a first heating allowing the at least partial dissipation of the thermal energy developed by the supply device 10.
  • the water undergoes a first heating by an electric heating device equipping the first upstream tank and arrives via the fluid connection in the second upstream tank 2 where it undergoes another heating, by the electric device equipping this tank.
  • the water reaches the downstream tank 1 (in the lower part) via the intermediate fluid connection.
  • the water undergoes a final heating to a temperature higher than that of storage of the upstream tanks 2 so as to be available at an outlet temperature setpoint at the outlet 6. If a large quantity of water at the set temperature must be supplied, all the tanks can obviously be heated to the desired temperature.
