Description

Title of the invention: System and method for mobile air conditioning of a dwelling comprising a plate with at least one Peltier effect device Technical field

[0001] The present invention relates to the air conditioning of buildings.

[0002] With global warming, periods of intense heat and heat waves tend to increase during the summer.

[0003] These high temperatures can be difficult for residents to bear and can generate or accentuate health problems (cardiac risks, more difficult blood circulation or risk of dehydration for example).

[0004] In addition, these high temperatures can remain high at night, particularly in urban areas. Indeed, the heat accumulated in urban structures (buildings, asphalt roads in particular) during the day heats the atmosphere at night, which prevents or limits the night-time cooling of the ambient air. As a result, it can be difficult to sleep at night in these environments and lack of sleep can exacerbate health problems.

[0005] It is therefore necessary to be able to cool at least certain living areas of a home during these periods of high heat. Prior art

[0006] Several air conditioning systems exist today.

[0007] Some of these air conditioning systems are fixed (i.e., not mobile, not portable). They then have a unit inside the home and an external unit. Consequently, these fixed air conditioning systems require work in the home to install them. Examples include heat pumps, which are fixed air conditioning systems.

[0008] Other air conditioning systems are mobile or portable. Generally, these systems include a movable unit, this movable unit being positioned in the room to be cooled. A pipe allows the heat captured in the room to be cooled to be rejected to the outside. The pipe then serves as a connection between the movable unit and a window or shutter which serves to isolate the internal air from the external air. However, these systems rely on a thermodynamic cycle using a compressor, which generates uncomfortable noise for people in the room to be cooled. In addition, these systems are bulky: the movable unit is large and the pipe also takes up space in the room.

[0009] Other air conditioning solutions consist of replacing the joinery (doors, windows, shutters) to make them suitable for air conditioning the accommodation.

[0010] Patent application WO 2015 / 132 308 A1 relates to a window with Peltier devices inserted into the window. As the Peltier devices are directly inserted into the window, in a non-removable manner, these systems are fixed and require the replacement of the entire window.

[0011] The aim of the invention is to: - design a mobile air conditioning system and process, i.e. one that can be moved: • at least within the accommodation itself, for example from one room to another, for example, in the living room during the day and in the bedroom at night • and preferably, which can also be moved from one accommodation to another (which can be easily taken to a holiday residence for example), - limit the noise of the air conditioning system. - limit system congestion. Summary of the invention

[0012] The invention relates to a mobile air conditioning system comprising a plate capable of being positioned under a roller shutter. In addition, said plate is electrically connected to an electrical outlet and said plate comprises at least one Peltier effect device.

[0013] Preferably, each Peltier effect device comprises two conductive sheets, each conductive sheet being on a separate side of the plate, at least two separate types of semiconductors connected together successively and alternately in series by a conductive element, the conductive sheets being in electrical contact with said conductive element.

[0014] Advantageously, the mobile air conditioning system comprises at least one fan, preferably opposite at least one Peltier effect device.

[0015] According to a variant of the invention, the plate comprises a support structure and several thermoelectric elements, each of the thermoelectric elements forming a Peltier effect device.

[0016] According to one configuration of the invention, the plate comprises at least one sliding part to adapt to a desired predetermined width, preferably the sliding part being arranged between two Peltier effect devices.

[0017] Advantageously, the height of the plate is between 10 mm and 500 mm, preferably between 10 mm and 300 mm.

[0018] The invention also relates to an air conditioning device comprising a window and a mobile air conditioning system according to one of the variants or combinations of variants described above. The window comprises a roller shutter and the mobile air conditioning system is positioned on the lower part of said window, under said roller shutter.

[0019] The invention also relates to a method for mobile air conditioning of a dwelling comprising a window equipped with a roller shutter. In this method, at least the following steps are implemented: - the plate of a mobile air conditioning system according to one of the variants or combinations of variants described above is placed on a ledge of said window equipped with said roller shutter, said plate being positioned under the roller shutter, so that the internal lateral surface of the plate is cooled by the at least one Peltier effect device; - the roller shutter is closed until it comes into contact with the said plate; - said electrical outlet is connected to supply it with electrical current, so that the internal lateral surface forms the cold surface of the at least one Peltier effect device.

[0020] Advantageously, the width of the plate can be adapted to the width of the roller shutter by at least one sliding part of the plate.

[0021] According to one configuration of the invention, the mobile air conditioning can be controlled by electronic means, preferably temperature measuring means and / or thermostats. List of figures

[0027] [Fig.5] represents a second embodiment of a plate of a mobile air conditioning system according to the invention. Description of the embodiments

[0028] For the purposes of the invention, the term "operating situation" or "operating position" means the situation in which the plate of the mobile air conditioning system is positioned under the roller shutter with one of the lateral surfaces of the plate on the internal side (facing the room to be cooled) which is cooled by the mobile air conditioning system, the other lateral surface of the plate, on the external side (facing the outside) is heated by the mobile air conditioning system.

[0029] The terms "vertical", "horizontal", "lateral", "internal" and "external" are understood to mean in the operating position. For example, the internal and external lateral surfaces of the plate are vertical or substantially vertical and the upper surface of the plate (on which the roller shutter rests) is substantially horizontal.

[0030] The term "transverse direction" refers to the direction from the outside to the inside of the part to be cooled. The terms "lateral" and "laterally", as well as "internal" and "external" or "internal" and "external" relate to the transverse direction.

[0031] The invention relates to a mobile air conditioning system capable of cooling a dwelling (or a building). For the purposes of the invention, a dwelling (or a building) may be of any type: house, residential building, office building, warehouses, commercial building, factory, leisure building, etc. More particularly, the mobile air conditioning system is intended to cool a room in the dwelling, the room comprising at least one window with a roller shutter.

[0032] In the present application, the term "interior" designates the space formed within the dwelling, while the term "exterior" designates what surrounds the dwelling.

[0033] The mobile air conditioning system comprises a plate to be positioned under a roller shutter. As a result, the plate is not fixed to the roller shutter or the window, which makes the system mobile and movable, from one room to another. For example, the mobile air conditioning system can be used at a roller shutter in the living room during the day and at a roller shutter in a bedroom at night. In addition, this system is space-saving: it is therefore possible to take the system for use in a holiday residence.

[0034] The term “mobile air conditioning system” means that the system can be moved easily and without having to carry out any work in the home.

[0035] For the purposes of the invention, the plate is understood to be a part which can be partially hollow so as to be able to integrate Peltier effect devices inside the plate. In other words, the plate may include cavities and the cavities may be partially or completely filled (filled) by Peltier devices.

[0036] Furthermore, the plate is electrically connected (electrically connected) to an electrical outlet and the plate comprises at least one Peltier device. As a result, the electrical outlet allows the plate and the Peltier devices to be supplied with electrical energy. The Peltier devices allow one of the two lateral surfaces of the plate to be cooled to be cooled, this lateral surface to be cooled being of course positioned on the inside (on the side of the room to be cooled). The other lateral surface of the plate is positioned on the outside (external atmosphere side) and the Peltier device tends to heat this external lateral surface. The internal lateral surfaces (the one to be cooled) and external lateral surfaces (the one heated by the Peltier device) are vertical or substantially vertical when the plate is in the operating position under the roller shutter.

[0037] The roller shutter serves to isolate, by a physical barrier, the air inside the room to be cooled (internal air) from the air outside (external air from the external atmosphere). This isolation of the two air flows allows the cooling of the internal air. In other words, the mobile air conditioning system is configured so that the plate and the roller shutter form a physical barrier to isolate the internal air from the external air.

[0038] The use of at least one Peltier effect device makes it possible to cool the room while limiting noise, in particular compared to air conditioning systems with a compressor, the compressor being a noisy element. In addition, the use of a Peltier effect device makes the air conditioning system compact and space-saving (for example a few centimeters in height over the width of the window, under the window): it can be moved from one room to another without difficulty and it can be easily moved in a vehicle to be used at a vacation spot or another place of residence. The vehicle in which the mobile air conditioning system according to the invention can be moved is a conventional automobile, which may be a city car. In other words, this vehicle is not necessarily large, nor capable of moving large masses (more than 3.5 tons for example) and does not require a special license to drive it.

[0039] In addition, the mobile air conditioning system according to the invention is not heavy. It can be handled by a single person, without requiring special handling means.

[0040] Preferably, the plate may comprise several Peltier effect devices, preferably regularly distributed over the plate. As a result, the temperature of the internal lateral surface to be cooled of the plate may be more homogeneous, which facilitates cooling.

[0041] Advantageously, each Peltier effect device may comprise two conductive sheets, each conductive sheet being on a separate lateral side of the plate. As a result, each conductive sheet may form a lateral surface of the plate, one serving to cool the room and the other being positioned on the external side, or alternatively, each conductive sheet of the Peltier effect device may be in mechanical contact (more particularly in thermal contact) with a lateral surface of the plate. The conductive sheets of each Peltier effect device are positioned vertically or substantially vertically, in the operating situation under the roller shutter, so as to form the internal or external lateral surfaces or so as to promote contact with these lateral surfaces.

[0042] Preferably, each Peltier effect device comprises at least two distinct types of semiconductors connected together successively and alternately in series by a conductive element, the conductive sheets being in electrical (and preferably mechanical) contact with the conductive element. Thus, the conductive element (a copper wire for example) successively connects in series alternately a first type of semiconductor then a second type of semiconductor. The semiconductors may comprise for example alloys of bismuth, antimony and / or tellurium. The successive connections of the conductive element with the two types of semiconductors generate a hot side and a cold side, cold and hot being understood relatively to each other and to the ambient air. Thus, the cold side is colder than the hot side on the one hand and than the internal ambient air on the other hand.The warm side is warmer than the cold side and the external ambient air on the other hand.

[0043] The use of conductive sheets on each side allows heat to be diffused on each side. The conductive sheets are thermal conductive sheets. They may preferably be electrically insulating or the Peltier device may comprise an electrically insulating substrate between the conductive sheet and the conductive element. For example, the conductive sheets may be made of ceramic or aluminum coated with an electrically insulating varnish.

[0044] Advantageously, the mobile air conditioning system may comprise at least one fan. The use of a fan makes it possible to increase the heat exchange by convection, either to increase the heat capture from the ambient air, on the internal side, or to increase the heat evacuation on the external side. The fan can therefore be positioned on the internal side or the external side.

[0045] Preferably, the mobile air conditioning system may comprise several fans, which may be: - either all on the internal side, - either all external side, - either internal or external side.

[0046] When positioned on the external side, the noise generated by these fans has less impact on people inside the room.

[0047] The use of a single fan on the internal side and / or external side (a single fan inside and / or a single fan outside) makes it possible to reduce noise, compared to a solution with several internal and / or external fans (at least two fans inside and / or at least two fans outside). Indeed, using a larger fan, rather than several fans of smaller sizes (relative to a single fan), makes it possible to limit noise.

[0048] Advantageously, at least one fan (preferably each fan) may be positioned opposite at least one Peltier device. By "positioned opposite", it is meant that the air flow generated by the fan is orthogonal or substantially orthogonal to the conductive sheets of the Peltier device and / or to the internal or external lateral surfaces of the plate, at the Peltier device. The air flow generated by the fan may suck in air from the Peltier device or conversely expel air towards the Peltier device. With an orthogonal air flow, the capture and removal of heat are optimized.

[0049] Alternatively or additionally, at least one fan (preferably each fan) may be positioned so that the air intake and / or discharge is substantially parallel to the lateral surface of the plate (which is to be cooled or which is being heated).

[0050] According to one configuration of the invention, the plate may comprise a support structure and several thermoelectric elements, each of the thermoelectric elements forming a Peltier effect device. Thus, the plate forms an assembly of Peltier effect devices on the support structure. This configuration is advantageous because it allows for simple assembly and an assembly that is easy for the user to transport. In addition, this assembly allows for easy replacement of the Peltier effect devices. In addition, by using a multitude of Peltier effect devices, the mobile air conditioning system can operate, in degraded mode, with one or more Peltier effect devices broken down, which would not be the case with a single Peltier effect device.

[0051] According to an advantageous variant of the invention, the plate may comprise at least one sliding part to adapt to a desired predetermined width. Indeed, thanks to the sliding part, the plate can adapt to the width of the roller shutter to form a sealed physical barrier to separate the internal air flow from the external air flow. Thus, the same system can be used in different locations with roller shutters of different widths. The sliding part can therefore comprise a predetermined adjustment width.

[0052] Preferably, the sliding part can be arranged between two effect devices Peltier, so as to facilitate sliding movement. For example, the sliding part can be positioned on the support structure of the plate. The sliding part can for example comprise a rail or a jack allowing the sliding movement of a part of the plate relative to another part of the plate to increase its width in particular. The width is understood to be the horizontal length of the plate (in operating position), the vertical length (in operating position) being the height of the plate and the thickness of the plate being the transverse distance between the two internal and external lateral surfaces (substantially vertical in operating position). In other words, the plate can comprise several parts (at least two parts) connected together by at least one sliding part (such as a rail).

[0053] Of course, the plate can comprise several sliding parts.

[0054] Advantageously, the height of the plate (in operating position) can be between 10 mm and 500 mm, preferably between 10 mm and 300 mm. These ranges are sufficient to obtain efficient cooling of the room in the home. In addition, these ranges make it possible to obtain a very compact, space-saving and lightweight air conditioning system, thus facilitating its transport.

[0055] Advantageously, the system may comprise electronic means, preferably temperature measuring means and / or thermostats, for controlling the system. For example, the system may comprise temperature measuring means and / or thermostats on at least one internal and / or external lateral surface of the plate or on at least one of the conductive sheets of at least one Peltier effect device. Thus, depending on the measured temperature, the activation of the air conditioning can be controlled or, on the contrary, its stopping, the activation of the air conditioning can then be reactivated when the measured temperature exceeds a certain threshold.

[0056] The invention also relates to an air conditioning device comprising a window and a mobile air conditioning system according to one of the variants or combinations of variants described above. The window comprises a roller shutter and the mobile air conditioning system is positioned on the lower part of said window, under said roller shutter. Thus, the device makes it possible to efficiently cool the room of the dwelling, in a simple and space-saving manner.

[0057] The invention also relates to a method for mobile air conditioning of a dwelling comprising a window equipped with a roller shutter. This method comprises at least the following steps: - the plate of a mobile air conditioning system according to one of the variants or combinations of variants described above is placed on the sill of the window equipped with the roller shutter. The plate is positioned under the roller shutter, so that the internal lateral (vertical) surface of the plate is cooled by the at least one Peltier effect device; - the roller shutter is closed until it comes into contact with the said plate, so as to isolate the internal air flow from the external air flow. This insulation allows the internal air flow to be cooled effectively; - the electrical outlet is connected to supply the mobile air conditioning system with electrical current, so that the internal (vertical) lateral surface forms the cold surface of the at least one Peltier device. Thanks to the electrical supply, the internal lateral surface can be cooled by the Peltier effect, while limiting noise. In addition, this method can be implemented on various windows equipped with a roller shutter.

[0058] By ledge is meant the lower part of the outer frame into which the window is inserted. The lower part is located under the window and it is on this part that the roller shutter rests when it is closed. This can be a ledge or an edge or any surface on which the roller shutter rests in the closed position.

[0059] Preferably, when the mobile air conditioning system comprises at least one sliding part for adapting the width of the system to the width of the roller shutter, the width of the plate can be adapted to the width of the roller shutter by at least one sliding part of the plate. By adapting the width of the system to that of the roller shutter, cooling can be more efficient and the method can be adapted to a large number of windows. If the roller shutter does not rest on any lower surface or the lower surface is not suitable for supporting the plate, it may be useful to provide for the addition or adaptation of a lower surface beforehand in order to be able to place the plate on this surface.

[0060] Advantageously, the mobile air conditioning can be controlled by electronic means, preferably temperature measuring means and / or thermostats.

[0061] For example, the system may comprise temperature measuring means and / or thermostats on at least one internal and / or external lateral surface of the plate or on at least one of the conductive sheets of at least one Peltier effect device. Thus, depending on the measured temperature, the activation of the air conditioning can be controlled or, on the contrary, its stopping, the activation of the air conditioning can then be reactivated when the measured temperature exceeds a certain threshold.

[0062] [Fig.l] illustrates, in a schematic and non-limiting manner, a view of the mobile air conditioning system according to the invention installed under a roller shutter, the view being that of a user inside the room to be cooled.

[0063] The mobile air conditioning system comprises a plate 2 positioned in the operating position under a roller shutter 1. Thus, the roller shutter 1 rests on the upper surface 3 (substantially horizontal) of the plate 2. Thus, the roller shutter 1 and the plate 2 form a physical barrier to separate the internal air flow (at inside the room to be cooled) from the external air flow (outside the room to be cooled).

[0064] The system also comprises an electrical outlet (not shown) for electrically connecting the plate 2 to an electrical network.

[0065] The plate 2 comprises one or more Peltier effect devices.

[0066] The plate 2 has a width L (of substantially horizontal direction in a situation of operation) substantially equal to the width of the roller shutter 1. In addition, the plate 2 has a vertical height H under the roller shutter.

[0067] As shown, the mobile air conditioning system may also include a fan 11, shown in dotted lines because it is optional. The fan 11 may be positioned on the inside of the room to be cooled or on the outside. As shown, the fan 11 is positioned such that the air discharge from the fan is substantially parallel to the width L of the plate. But of course, it could be positioned such that the air suction at the inlet of the fan 11 is substantially parallel to the width L of the plate.

[0068] [Fig. 2] illustrates, in a schematic and non-limiting manner, a cross-sectional view of a mobile air conditioning system according to the invention. By cross-sectional view, we mean a section in a transverse direction plane going from the external lateral surface (4) of the plate to the internal lateral surface (5) of the plate.

[0069] The mobile air conditioning system comprises a plate 2 connected to an electrical outlet (not shown). In the operating position, as shown, the plate 2 is positioned under the rolling shutter 1. In other words, the rolling shutter 1 rests on the upper surface 3 (substantially horizontal) of the plate 2. Thus, the rolling shutter 1 and the plate 2 form a physical barrier separating the internal air flow INT on the side of the room to be cooled from the external air flow EXT on the side of the outside atmosphere.

[0070] The plate 2 comprises an external lateral surface 4 and an internal lateral surface 5. These internal lateral surfaces 4 and external 5 are substantially vertical. The internal lateral surface 5 is the surface that is to be cooled using one or more Peltier effect devices that are placed (and not shown) in the plate 2.

[0071] The plate 2 has a vertical height H below the roller shutter 1 and a thickness e, in the transverse direction. As shown, the thickness e of the plate 2 is greater than the thickness, in the transverse direction, of the roller shutters, but the thickness e of the plate could be less than or equal to the thickness of the roller shutters.

[0072] The mobile air conditioning system may also include one or more fans 11 on the internal side and one or more fans 10 on the external side. These fans 10 and 11 are shown in dotted lines to emphasize the fact that they are optional and not mandatory.

[0073] As shown, the fans 10 and 11 are configured to suck air from a transverse direction (or in the opposite direction from the inside to the outside for the fan 11) and to discharge the air, substantially in the same direction, towards the plate. In other words, the fans 10 and 11 discharge the air towards the lateral surface, respectively external 4 and internal 5, of the plate 2. The bold arrows represent the suction and discharge of air. Of course, the fans 10 and 11 could be configured conversely to suck air, in the transverse direction (or in the direction opposite to the transverse direction for the fan 10), from the lateral surface, respectively external 4 and internal 5, of the plate 2 and discharge the air in the direction opposite this surface.In other words and in these two inverse configurations, the fans 10 and 11 are opposite the lateral surfaces, respectively external 4 and internal 5, of the plate 2.

[0074] [Fig. 3] illustrates, in a schematic and non-limiting manner, a plate of a mobile air conditioning system according to the invention.

[0075] Plate 2 comprises several Peltier effect devices 9, shown in black, regularly distributed over plate 2.

[0076] The plate 2 has a width L, a vertical height H and a thickness e, in the transverse direction.

[0077] The plate 2 comprises an internal lateral surface 5 which is the vertical surface facing the part to be cooled and an external lateral surface 4 which is the one which is heated by the Peltier effect devices 9, and which faces the external atmosphere.

[0078] The Peltier effect devices 9 each comprise an internal conductive sheet 7 which is in contact with the internal lateral surface 5 of the plate (and which can be confused with this surface).

[0079] The plate 2 may comprise, as shown, a support structure 12, capable of receiving the different Peltier effect devices 9, so as to facilitate the assembly and possible replacement of the Peltier effect devices 9.

[0080] [Fig.4] illustrates, in a schematic and non-limiting manner, a Peltier effect device of a plate of a mobile air conditioning system according to the invention.

[0081] The Peltier effect device 9 comprises two types of semiconductors SCI and SC2 which are connected in series, alternately, by a conductive element 6 such as a copper wire. The semiconductors SCI and SC2 are of different nature, which is schematically illustrated by different shapes in the figure.

[0082] Furthermore, on each side of the Peltier effect device 9, the conductive element 6 is in contact (preferably fixed) with a conductive sheet 7 on the inner side of the part to be cooled and with a conductive sheet 8 on the outer side of the part to be cooled. These conductive sheets 7 and 8 are thermally conductive and they can be insulating. electrical or be covered with an electrically insulating layer, such as an insulating varnish.

[0083] In the figure, the electric current I arrives from the right and moves successively through the conductive element 6, and through the semiconductors SCI and SC2. The bold arrows represent the movement of the electric current I in the conductive element 6 to obtain a cold conductive sheet 7 on the side of the part to be cooled and a hot conductive sheet 8 on the external side. Of course, by reversing the movement of the current, the cold and hot conductive sheets are reversed.

[0084] [Fig. 5] illustrates, in a schematic and non-limiting manner, a second embodiment of a plate of a mobile air conditioning system according to the invention.

[0085] Plate 2 comprises several Peltier effect devices 9, shown in black, regularly distributed over plate 2.

[0086] Plate 2 has a width L and a vertical height H.

[0087] The plate 2 comprises an internal lateral surface which is the vertical surface in vis- opposite the part to be cooled and an external lateral surface which is the one which is heated by the Peltier effect devices 9, and which is opposite the external atmosphere.

[0088] The plate 2 may comprise, as shown, a support structure, capable of receiving the different Peltier effect devices 9, so as to facilitate the assembly and possible replacement of the Peltier effect devices 9.

[0089] Furthermore, in this embodiment, the plate 2 comprises a sliding portion 14 so as to adjust the width L of the plate to an adjustment length Lreg. For example and as shown, the plate comprises at least a first portion 15 and a second portion 13 separated and connected to each other by the sliding portion 14. The first and second portions 13 and 15 of the plate comprise Peltier effect devices 9 while the sliding portion 14 is located between two Peltier effect devices 9. Examples

[0090] To cool a room of 12 m2, an air conditioning system power of 1500W is generally sufficient. Indeed, it is generally considered that the power of the necessary air conditioning generally varies between 65 W / m2 and 125 W / m2. Considering a roller shutter width of 1 m (and therefore a width of the mobile air conditioning system plate of 1m) and Peltier effect devices with a power of 9 W / cm2, a plate height of 2 cm is sufficient to reach 1500 W of system power. It is therefore possible to obtain a system according to the invention, which is very compact, light and therefore easily transportable. In addition, the system of the invention can be installed without prior installation work.
