Abstract
Description
Title of the invention: Hydraulic storage module comprising a perforated pipe. Technical field
[0001] The present invention relates to the field of thermal regulation of a building by means of a hydraulic circuit.
[0002] More particularly, the invention relates to a hydraulic storage module for a building's thermal regulation system and such an installation. Technological background
[0003] A thermal control installation, i.e. heating or cooling, generally comprises a thermal control device, one or more receiving elements and a hydraulic circuit connected to the thermal control device and the receiving elements to form a fluid circulation loop.
[0004] The thermal regulation device is, for example, a boiler or a heat pump. The receiving elements are, for example, one or more of a radiator, a towel warmer, a water heater and underfloor heating.
[0005] A hydraulic storage module, also called a buffer tank or storage module, can be integrated into the hydraulic circuit to store excess heating water produced by the thermal control device. Thus, the hydraulic storage module makes it possible to maintain a reserve of thermal energy ready to be used as needed by the building, limiting the demands placed on the thermal control device. This is particularly useful when the thermal control device is a heat pump or uses a renewable energy source, so as to store the thermal energy produced when it is available or when its production is most optimal.
[0006] To perform this function, the hydraulic module is connected simultaneously to the supply and return circuits of the hydraulic circuit, between the thermal regulation device and the receiving elements.
[0007] With reference to [Fig. 1], an example of a hydraulic storage module 10 is shown. This hydraulic storage module 10 is connected between a thermal control device 26 and a plurality of receiving elements 28 via a hydraulic circuit 30. The hydraulic circuit 30 comprises a heating water supply circuit 32 and a heating water return circuit 34.
[0008] The hydraulic storage module 10 comprises a reservoir 12 having four orifices: - a first 14 and a second 16 starting orifices, - a first 18 and a second 20 return ports.
[0009] The first 14 and second 16 outlet ports are hydraulically connected to the heating water outlet circuit 32.
[0010] The first 18 and second 20 return ports are hydraulically connected to the heating water return circuit 34.
[0011] Thus, the first outlet 14 and return 18 ports are hydraulically connected to the regulating device 26. The second outlet 16 and return 20 ports are hydraulically connected to the receiving elements 28.
[0012] It is known to form the first and second supply ports, as well as the first and second return ports, as open ports. An "open port" is defined as one in which the port opens directly into the internal cavity of the reservoir 12 with a completely unobstructed pipe section, originating from a side wall of the hydraulic module. Therefore, there is no reduction in cross-section at the inlet to the reservoir 12. Consequently, the fluid supplying the tank or being drawn from the reservoir 12 encounters no obstacle or deflector.
[0013] It has been observed that significant mixing occurs within a tank equipped with open orifices. However, it is important to ensure thermal stratification of the water present in the tank to guarantee good energy performance.
[0014] The circulation of water in the reservoir leads to a homogenization of the temperature of the fluid in the reservoir and therefore a significant temperature difference between the temperature of the water supplying the reservoir at the first outlet 14 and the temperature of the water at the second outlet 16. This mixing causes a dissipation of thermal energy in the reservoir and therefore reduced performance of the hydraulic storage module.
[0015] Figures 2 and 3 respectively show the distribution of the heating water circulation velocity (m / s) and the distribution of the heating water temperature (°C) within the hydraulic module during the operation of the thermal control system using a known hydraulic module with open orifices. Figure 2 shows the water circulation within the reservoir as well as the temperature difference between the first 14 and second 16 outlet orifices.
[0016] In [Fig. 2], the maximum velocities are visible at the first 14 and second 16 outlet orifices, as well as at the first 18 and second 18 return orifices. The minimum velocities are visible within the reservoir 12, in the lower, upper, and central portions.
[0017] Figure 4 shows the evolution of the heating water temperature at the first outlet 14 (first curve 40), the second outlet 16 (second curve 42), the first return outlet 18 (third curve 44), and the second return port 20 (fourth curve 46) and the overall temperature in reservoir 12 (fifth curve 48). The y-axis represents the water temperature in degrees Celsius and the x-axis represents the elapsed time in seconds.
[0018] It can be seen in [Fig. 4] that the difference in water temperature between the first 14 and second 16 starting orifices is approximately 4.5°C from 250 seconds.
[0019] Other solutions have been used to limit mixing, such as bent tubes or deflector plates placed inside the tank at the orifices. However, these solutions do not sufficiently limit water mixing inside the tank, so the energy performance of the hydraulic module remains inadequate.
[0020] There is therefore a need for a hydraulic storage module to improve thermal stratification within the tank in order to obtain better energy performance. Summary of the invention
[0021] To this end, the invention proposes a hydraulic storage module for a building's thermal regulation system, the hydraulic heat transfer fluid storage module being configured to be hydraulically connected to a heat transfer fluid supply circuit and a heat transfer fluid return circuit of the heating system to store thermal energy by means of the heating water present in the tank, the hydraulic storage module comprising: - a heat transfer fluid tank extending along a central longitudinal axis, - a first and a second supply orifice intended to be hydraulically connected to the heat transfer fluid supply circuit, - a first and a second return orifice intended to be hydraulically connected to the heat transfer fluid return circuit,characterized in that the hydraulic storage module further comprises: - a supply pipe passing through the heat transfer fluid reservoir and extending from the first supply port to the second supply port, at least one first circulation port being formed in the supply pipe to allow fluid communication between an internal space of the supply pipe and the reservoir.
[0022] The integration of a supply line joining the first and second supply ports makes it possible to significantly limit the mixing of the liquid present in the tank when the liquid from the thermal regulation device feeds the first supply port.
[0023] This limitation of mixing makes it possible to limit disturbances in the reservoir and therefore to guarantee good thermal stratification of the liquid present in the reservoir. The temperature difference of the water between the first and second outlets is significantly reduced. This limitation of the temperature difference is particularly visible in Figures 10 and 14, which show a temperature difference of less than 0.15°C.
[0024] The proposed solution consisting of a conduit joining two orifices is also simple to manufacture and therefore inexpensive.
[0025] The starting pipe extends along a starting axis. The starting axis is preferably perpendicular to the central longitudinal axis. The starting axis preferably intersects the central longitudinal axis.
[0026] The hydraulic storage module according to the invention conforms to that shown and described in relation to [Fig. 1] and differs from the latter in that a supply line has been integrated into the reservoir. The hydraulic storage module according to the invention is integrated into a building thermal control system conforming to that described in relation to [Fig. 1].
[0027] The heating fluid is preferably heating water from a heating circuit. The heat transfer fluid may comprise water and one or more additives.
[0028] In this description, the terms heating water, water or liquid will be used interchangeably, all of these terms referring to the heat transfer fluid.
[0029] The thermal control device can be configured to increase the temperature of the heat transfer fluid. The thermal control device can also be configured to have several operating modes, including a heating mode and a cooling mode.
[0030] The term "conduit" refers to a conduit having at least one wall extending continuously between two ends. Thus, a conduit situated between two orifices corresponds to a wall or a portion of a wall extending continuously between these two orifices. A curved wall, therefore, corresponds to an angular portion of a cylindrical conduit extending between two orifices. In other words, the starting conduit may consist, between two orifices, of only a continuous portion of wall extending perpendicularly to the central longitudinal axis between the two orifices. Consequently, the first and second circulation orifices may be cutouts made in the conduit wall, potentially removing at least half of the conduit wall situated within the reservoir.Alternatively, the first and second circulation ports can be cutouts in the pipe wall, potentially removing up to 80% of the pipe wall inside the tank. The remaining pipe wall then acts as an obstacle to the flow of the heat transfer fluid towards the center of the tank, thus limiting disturbances and mixing within the tank.
[0031] According to one embodiment of the hydraulic storage module, it further comprises a return line passing through the reservoir and extending from the first return port to the second return port, at least one second circulation port being formed in the return line to allow fluid communication between an interior space of the return line and the reservoir.
[0032] The integration of a return line joining the first and second return ports makes it possible to significantly limit the mixing of the liquid present in the reservoir when liquid from the receiving organs feeds the second return port.
[0033] The return line extends along a return axis. The return axis is preferably perpendicular to the central longitudinal axis. The return axis preferably intersects the central longitudinal axis.
[0034] According to one embodiment of the hydraulic storage module, the tank has an upper portion and a lower portion, with at least one first circulation orifice being oriented towards the upper portion of the tank. At least one second circulation orifice may be oriented towards the lower portion of the tank. Thus, the first and second circulation orifices are located in an area of the tank that limits the mixing of the water present in the supply and return lines towards the opposite area of the tank. In other words, this prevents the water in the upper part of the tank, which has a higher temperature, from mixing with the water in the lower part of the tank, which has a lower temperature.
[0035] According to one embodiment of the hydraulic storage module, the tank comprises a lower wall, an upper wall, and a shell extending between the lower and upper walls. At least one of these circulation ports is oriented towards the upper portion of the tank. At least one of these circulation ports may be oriented towards the lower portion of the tank. Thus, the first and second circulation ports are oriented so as to limit the mixing of water present in the supply and return lines towards the opposite area of the tank. When water flows through the first circulation ports, by injection or suction depending on the operating cycle, the water circulation has very little effect on the thermal stratification of the tank.
[0036] To achieve this orientation, the first and second circulation orifices are respectively formed at the level of an upper portion of the supply pipe and a lower portion of the return pipe.
[0037] The lower and upper portions correspond to an intellectual subdivision of the reservoir and therefore do not correspond to a physical delimitation of the reservoir. The lower and upper portions can each thus correspond to 50% of the tank's height along the central longitudinal axis. Conversely, the lower and upper walls correspond to physical elements of the tank.
[0038] According to one embodiment of the hydraulic storage module, the first and second outlet ports are formed in the upper portion of the tank, while the first and second return ports are formed in the lower portion of the tank. This allows the tank to have a volume of hot water in the upper portion and a volume of water at a lower temperature in the lower portion.
[0039] According to one embodiment of the hydraulic storage module, a plurality of first circulation ports and / or a plurality of second circulation ports. A plurality of ports allows the water supply or suction areas to be distributed over the external surface of the supply and / or return pipe. This also allows the water supply or suction flow rate to be increased.
[0040] According to one embodiment of the hydraulic storage module, said at least one first circulation orifice and / or said at least one second circulation orifice are formed along a direction perpendicular to the central longitudinal axis of the tank. This allows for the distribution of the water suction or injection along the length of the supply and / or return pipe while increasing the water flow cross-section.
[0041] According to one embodiment of the hydraulic storage module, at least one first circulation orifice and / or at least one second circulation orifice are formed near the central longitudinal axis. Thus, at least one first circulation orifice and / or at least one second circulation orifice are arranged around a central area of the supply line and / or the return line. This arrangement helps to limit the risk of the tank walls acting as deflectors and thus causing unwanted mixing of the water in the tank.
[0042] Said at least one first circulation orifice and / or said at least one second circulation orifice are formed at the level of an area centered around the central longitudinal axis and which may represent up to 100% of the length of the starting pipe and / or the return pipe, respectively, along a direction perpendicular to the central longitudinal axis.
[0043] According to an embodiment of the hydraulic storage module, said at least one first circulation orifice and / or said at least one second circulation orifice being one of: a local perforation formed in a wall of the supply or return pipe and a longitudinal recess in a wall of the supply or return pipe.
[0044] According to a first embodiment, said at least one first circulation orifice and / or said at least one second circulation orifice is a plurality of local perforations arranged on an upper portion of the supply pipe and / or a lower portion of the return pipe and extending along a direction perpendicular to the central longitudinal axis.
[0045] According to a second embodiment, said at least one first circulation orifice and / or said at least one second circulation orifice is a longitudinal recess formed on an upper portion of the supply pipe and / or a lower portion of the return pipe and extending along a direction perpendicular to the central longitudinal axis. The supply pipe and / or the return pipe may thus have only one half-wall corresponding to a pipe half in which the half-wall is oriented towards the center of the reservoir, i.e., opposite the upper wall for the supply pipe and opposite the lower wall for the return pipe.
[0046] The longitudinal recess can be a groove or a channel formed through a wall of the supply and / or return pipe.
[0047] The invention also proposes a thermal regulation system for a building, comprising: - a thermal regulation device, - at least one receptor organ, - a hydraulic thermal regulation circuit in fluid communication with the thermal regulation device and said at least one receiving element to form a thermal regulation loop, the hydraulic circuit comprising a supply circuit hydraulically connecting the thermal regulation device to said at least one receiving element and a return circuit hydraulically connecting said at least one receiving element to the thermal regulation device, - a hydraulic storage module as described above connected to the supply and return circuits between the thermal control device and said at least one receiver to store thermal energy by means of the heating water present in the tank.
[0048] Thus, when the thermal control device supplies the first outlet with water, this water flows through the outlet pipe and reaches the second outlet to supply the receiving components without causing any disturbance in the tank. The same applies to the water from the receiving components that feeds the second return outlet; this water flows through the return pipe and reaches the first return outlet without causing any disturbance in the tank.
[0049] When the water flow rate in the hydraulic circuit connected to the thermal control device is greater than the water flow rate in the hydraulic circuit connected At the receiving organs, the difference in flow rate between the first and second supply ports creates an excess flow in the supply line, resulting in the transfer of excess water to the reservoir through the first circulation openings. Similarly, a difference in flow rate between the first and second return ports creates an excess flow in the return line, resulting in water being drawn from the reservoir through at least one other circulation opening.

[0065] For the sake of clarity, the same references designating the same elements according to the state of the art and according to the invention are used for all figures.
[0066] The concept of the invention is described more fully below with reference to the accompanying drawings, in which embodiments of the concept of the invention are shown. In the drawings, the size and relative sizes of the elements may be exaggerated for clarity. Similar numbers refer to similar elements in all the drawings. However, this concept of the invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are offered so as to make this description complete and to communicate the scope of the concept of the invention to those skilled in the art.
[0067] A reference throughout the specification to "an embodiment" means that a particular feature, structure, or characteristic described in relation to an embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrase "in an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Moreover, the term "including" does not exclude other elements or steps.
[0068] The invention relates to a hydraulic storage module, a thermal regulation installation comprising such a hydraulic storage module and a method for thermally regulating such an installation.
[0069] With reference to figures 5 and 6, a hydraulic storage module 50 for heat transfer fluid, also called a module or buffer tank, is connected between a thermal control device 26 and one or more receiving organs 28 via a hydraulic circuit 30. The hydraulic circuit 30 includes a heating water supply circuit 32 and a heating water return circuit 34.
[0070] The reservoir 12 extends along a central longitudinal axis A. The reservoir comprises a lower wall 13, an upper wall 15 and a ferrule 17 extending between the lower wall 13 and upper wall 15. The central longitudinal axis A is the axis of revolution of the reservoir 12.
[0071] The hydraulic storage module 50 comprises a reservoir 12 having four orifices: - a first 14 and a second 16 starting ports, - a first 18 and a second 20 return ports.
[0072] The first 14 and second 16 outlet ports are hydraulically connected to the heating water outlet circuit 32.
[0073] The first 18 and second 20 return ports are hydraulically connected to the heating water return circuit 34.
[0074] Thus, the first outlet 14 and return 18 ports are hydraulically connected to the regulating device 26. The second outlet 16 and return 20 ports are hydraulically connected to the receiving elements 28.
[0075] The hydraulic storage module 50 further includes a supply line 52 passing through the reservoir 12 and extending from the first supply port 16 to the second supply port 18.
[0076] A plurality of first circulation ports 54 are formed in the starting pipe 52 to allow fluid communication between an internal space of the starting pipe 52 and the reservoir 12.
[0077] The hydraulic storage module 50 further includes a return line 58 passing through the reservoir 12 and extending from the first return port 18 to the second return port 20.
[0078] A plurality of second circulation ports 60 are formed in the return line 58 to permit fluid communication between an internal space of the return line 58 and the reservoir 12.
[0079] The plurality of first circulation orifices 54 is oriented towards the upper wall 15 of the reservoir, while the plurality of second circulation orifices 60 is oriented towards the lower wall 13 of the reservoir. Thus, the mixing of the liquid Heat transfer fluid is greatly reduced and thermal stratification within the tank can be guaranteed or greatly improved.
[0080] The supply pipes 52 and return pipes 58 extend respectively along a supply axis B and a return axis C. The supply axes B and return axes C are preferably perpendicular to the central longitudinal axis A. The supply axes B and return axes C preferably intersect the central longitudinal axis A.
[0081] The supply lines 52 and return lines 58 are identical in this example illustrated in figures 5 and 6.
[0082] An isolated view of the supply line 52 is shown in [Fig. 7]. The supply line 52 comprises a central portion 62 through which the flow ports 54 are formed. The supply line 52 also comprises two end portions 64, each fixed at one end of the central portion 62. The end portions 64 are preferably configured to serve as a hydraulic connection with a line of the hydraulic circuit 30. The end portions 64 are, for example, threaded sleeves.
[0083] The central portion 62 and the end portions 64 can be made in one and the same piece.
[0084] The return pipe 58 can be identical to the starting pipe 52 and therefore have the same configuration described above.
[0085] Figures 8 and 9 respectively represent the distribution of the heating water circulation velocity (m / s) and the distribution of the heating water temperature (°C) within the hydraulic module 50 comprising supply pipes 52 and return pipes 58 according to a configuration comprising a plurality of circulation ports as shown in Figures 5 to 7.
[0086] Figure 8 shows that the liquid velocity within the supply line 52 and return line 58 is homogeneous. It is also observed that the circulation of the liquid between the reservoir 12 and the supply line 52 and return line 58 results in small velocity variations and few disturbances within the reservoir 12.
[0087] In [Fig. 8], the maximum velocities are visible within the supply and return pipes. The minimum velocities are visible within the reservoir 12, in the lower, upper and central portions.
[0088] Similarly, it can be seen in [Fig.9] that the temperature within the reservoir 12, the supply line 52 and the return line 58 is homogeneous.
[0089] Figure 10 shows the evolution of the heating water temperature at the first outlet 14 (first curve 40), the second outlet 16 (second curve 42), the first return outlet 18 (third curve 44), the second return outlet 20 (fourth curve 46), and the temperature in the reservoir 12 (fifth curve 48). The ordinate axis represents the water temperature in degrees Celsius and the abscissa axis represents the elapsed time in seconds.
[0090] Figure 10 shows that the temperature difference of the water between the first 14 and second 16 outlet orifices is 0°C throughout the operation studied. The first 40 and second 42 curves are superimposed, indicating that the temperature at the first 14 and second 16 outlet orifices is essentially the same. The configuration of the hydraulic module 50, with outlet 52 and return 58 pipes perforated towards the upper 15 and lower 13 walls, makes it possible to maintain an essentially identical temperature between the first 14 and second 16 outlet orifices and thus improve the energy performance of the hydraulic module 50.
[0091] With reference to [Fig. 11], another embodiment of the outlet pipe 52 is shown. In this embodiment, the outlet pipe 52 has a single circulation orifice 54 extending in the form of a longitudinal recess.
[0092] In this embodiment, the outlet pipe 52 has only one half-wall 66 corresponding to one half of the pipe. The half-wall 66 is oriented towards the center of the reservoir 12, i.e. opposite the upper wall 15.
[0093] More particularly, the central portion 62 of the starting pipe 52 forms a half-wall 66 which extends between the end portions 64.
[0094] The return line 58 can be identical to the starting line 52 and therefore have the same configuration described above.
[0095] Figures 13 and 12 respectively represent the distribution of the heating water circulation velocity (m / s) and the distribution of the heating water temperature (°C) within the hydraulic module 50 comprising supply pipes 52 and return pipes 58 according to a half-wall configuration as shown in [Fig.11].
[0096] Figure 13 shows that the liquid velocity within the supply line 52 and return line 58 is homogeneous. It is also observed that the circulation of the liquid between the reservoir 12 and the supply line 52 and return line 58 results in small velocity variations and few disturbances within the reservoir 12.
[0097] In [Fig. 13], the maximum velocities are visible within the supply and return pipes. The minimum velocities are visible within the reservoir 12, in the lower, upper and central portions.
[0098] Similarly, it can be seen in [Fig. 12] that the temperature within the reservoir 12, the supply line 52 and the return line 58 is homogeneous.
[0099] Figure 14 shows the evolution of the heating water temperature at the first outlet 14 (first curve 40), and at the second outlet. The graph shows the starting point 16 (second curve 42), the first return port 18 (third curve 44), the second return port 20 (fourth curve 46), and the temperature in tank 12 (fifth curve 48). The y-axis represents the water temperature in degrees Celsius, and the x-axis represents the elapsed time in seconds.
[0100] Figure 14 shows that the temperature difference of the water between the first 14 and second 16 outlets is 0.15°C throughout the operation studied. The first 40 and second 42 curves are almost superimposed, indicating that the temperature at the first 14 and second 16 outlets is essentially the same. The configuration of the hydraulic module 50, with half-walled supply 52 and return 58 pipes and circulation orifices oriented towards the upper 15 and lower 13 walls, maintains a virtually identical temperature between the first 14 and second 16 outlets, thus improving the energy performance of the hydraulic module 50.
