Description

La présente invention concerne un dispositif de climatisation d'une salle, notamment une salle pour passagers d'un véhicule de transport public, et plus particulièrement d'un véhicule ferroviaire.The present invention relates to an air conditioning device of a room, including a room for passengers of a public transport vehicle, and more particularly of a railway vehicle.

On connait déjà, dans l'état de la technique, un dispositif de climatisation comprenant des moyens centraux de conditionnement de la température d'air, et un circuit de circulation de l'air conditionné entre les moyens centraux et la salle à climatiser.Already known in the state of the art, an air conditioning device comprising central means for conditioning the air temperature, and a circuit for circulating air conditioning between the central means and the room to be air-conditioned.

Un tel dispositif de climatisation est particulièrement encombrant. En effet, des moyens centraux de conditionnement d'air sont encombrants, et un circuit de circulation d'air comporte nécessairement des conduites présentant de grandes sections transversales pour permettre la circulation d'un flux d'air suffisant pour la climatisation de la salle. Le circuit de circulation comporte également des moyens de ventilation pour la mise en circulation de l'air, ces moyens de ventilation étant également encombrants.Such an air conditioning device is particularly bulky. Indeed, central air conditioning means are bulky, and an air circulation circuit necessarily comprises pipes having large cross sections to allow the circulation of a sufficient air flow for the air conditioning of the room. The circulation circuit also comprises ventilation means for circulating the air, these ventilation means being equally bulky.

Par ailleurs, la projection d'air climatisé dans la salle est généralement inconfortable pour les personnes qui y sont présentes.In addition, the projection of air conditioning in the room is generally uncomfortable for the people who are there.

Le document EP 2 868 502 A1 décrit un dispositif de climatisation conforme au préambule de la revendication 1.The document EP 2 868 502 A1 describes an air conditioning device according to the preamble of claim 1.

Les moyens centraux selon l'invention sont destinés au conditionnement de liquide, et sont donc moins encombrants que des moyens de conditionnement d'air. De même, des conduites de circulation de liquide pour le circuit selon l'invention sont moins encombrantes que des conduites de circulation d'air.The central means according to the invention are intended for liquid conditioning, and are therefore less bulky than air conditioning means. Likewise, liquid circulation lines for the circuit according to the invention are less bulky than air circulation lines.

Il en résulte que le dispositif de climatisation selon l'invention est moins encombrant qu'un dispositif de climatisation de l'état de la technique.As a result, the air conditioning device according to the invention is less bulky than an air conditioning device of the state of the art.

Par ailleurs, les sorties d'air sont agencées au niveau du sol, si bien que l'air climatisé ne monte dans la salle que par convection naturelle liée aux personnes présentes dans cette salle. La vitesse de circulation d'air climatisé dans la salle est donc relativement faible, si bien que cette circulation d'air est plus confortable que dans l'état de la technique.In addition, the air outlets are arranged at ground level, so that air conditioning climbs into the room only by natural convection related to people in this room. The air circulation rate in the room is therefore relatively low, so that this circulation of air is more comfortable than in the state of the art.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux figures annexées, parmi lesquelles :

  • La figure 1 représente schématiquement un dispositif de climatisation selon un exemple de mode de réalisation de l'invention ;
  • La figure 2 est une vue en perspective représentant partiellement le dispositif de climatisation de la figure 1.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures, among which:
  • The figure 1 schematically represents an air conditioning device according to an exemplary embodiment of the invention;
  • The figure 2 is a perspective view partially representing the air conditioning device of the figure 1 .

On a représenté sur les figures un dispositif 10 de climatisation d'au moins une salle 12 destinée à accueillir des passagers d'un véhicule de transport public, notamment d'un véhicule ferroviaire. On notera que le dispositif de climatisation 10 pourrait être agencé dans toute salle destinée à accueillir des personnes, par exemple des salles de locaux.There is shown in the figures a device 10 for air conditioning of at least one room 12 intended to accommodate passengers of a public transport vehicle, including a railway vehicle. It will be noted that the air conditioning device 10 could be arranged in any room intended to accommodate people, for example rooms of premises.

Le dispositif de climatisation 10 comporte des moyens centraux 14 de conditionnement de la température d'un liquide caloporteur. De tels moyens centraux de conditionnement 14 sont classiques et comportent par exemple une pompe à chaleur. Il est à noter que de tels moyens centraux de conditionnement 14 sont peu encombrants, notamment en comparaison avec des moyens de conditionnement d'air de l'état de la technique.The air conditioning device 10 comprises central means 14 for conditioning the temperature of a heat transfer liquid. Such central conditioning means 14 are conventional and comprise for example a heat pump. It should be noted that such central conditioning means 14 are compact, particularly in comparison with air conditioning means of the state of the art.

Avantageusement, le liquide caloporteur est de l'eau, notamment de l'eau glycolée.Advantageously, the coolant is water, especially glycol water.

Le dispositif de climatisation 10 comporte par ailleurs un circuit 16 de circulation du fluide caloporteur, passant par les moyens centraux de conditionnement 14, et comprenant au moins une pompe de circulation du liquide caloporteur. Le circuit de circulation 16 comporte des conduites 18 de circulation du liquide caloporteur. De telles conduites 18 sont peu encombrantes, notamment en comparaison avec des conduites de circulation d'air climatisé de l'état de la technique.The air conditioning device 10 furthermore comprises a circuit 16 for circulating the heat transfer fluid, passing through the central conditioning means 14, and comprising at least one coolant circulation pump. The circulation circuit 16 comprises conduits 18 for circulating the coolant liquid. Such ducts 18 are not very cumbersome, especially in comparison with conditioned air circulation lines of the state of the art.

Le dispositif de climatisation 10 comporte par ailleurs au moins une unité de climatisation 20, logée dans l'une des salles 12.The air conditioning device 10 also comprises at least one air conditioning unit 20, housed in one of the rooms 12.

Chaque salle 12 loge de préférence une pluralité d'unités de climatisation 20.Each room 12 preferably houses a plurality of air conditioning units 20.

Par ailleurs, le dispositif de climatisation 10 peut comporter des unités de climatisation 20 logées dans des salles différentes.Furthermore, the air conditioning device 10 may comprise air conditioning units 20 housed in different rooms.

Comme cela est représenté sur la figure 2, chaque unité de climatisation 20 comprend une enceinte 22, présentant une ouverture 24 d'entrée d'air depuis la salle 12 et une ouverture 26 de sortie d'air climatisé vers la salle 12, les ouvertures d'entrée 24 et de sortie 26 d'air étant toutes deux agencées au niveau du sol de la salle 12.As shown on the figure 2 each air conditioning unit 20 comprises an enclosure 22 having an air inlet opening 24 from the room 12 and an air conditioning outlet opening 26 to the room 12, the inlet 24 and outlet openings 26 both of which are arranged at the floor level of the room 12.

Par exemple, chaque ouverture d'entrée d'air 24 débouche en sous-châssis ou en bas d'une paroi latérale de la salle. Avantageusement, les ouvertures de sortie 26 sont ménagées dans un panneau de sol 28, délimitant en partie chaque enceinte 22.For example, each air inlet opening 24 opens into a sub-frame or down a side wall of the room. Advantageously, the outlet openings 26 are formed in a floor panel 28, partially delimiting each chamber 22.

En variante, les ouvertures d'entrée 24 et de sortie 26 sont toutes ménagées dans le panneau de sol 28 délimitant en partie chaque enceinte 22.In a variant, the inlet and outlet openings 24 are all formed in the floor panel 28 partially delimiting each chamber 22.

Chaque unité de climatisation 20 comporte par ailleurs un organe de ventilation 30, logé dans l'enceinte 22, propre à faire circuler de l'air dans l'enceinte 22 depuis l'ouverture d'entrée 24 vers l'ouverture de sortie 26. L'organe de ventilation 30 est donc logé au niveau du sol, notamment sous le panneau de sol 28.Each air conditioning unit 20 further includes a ventilation member 30, housed in the chamber 22, able to circulate air in the chamber 22 from the inlet opening 24 to the outlet opening 26.

Avantageusement, l'organe de ventilation 30 est un ventilateur tangentiel. De préférence, l'organe de ventilation 30 présente des dimensions réduites, ce qui est possible du fait que le dispositif 10 selon l'invention ne requiert qu'une faible vitesse de sortie d'air.Advantageously, the ventilation member 30 is a tangential fan. Preferably, the ventilation member 30 has reduced dimensions, which is possible because the device 10 according to the invention requires only a low air outlet speed.

On notera que l'enceinte 22 est par exemple commune à plusieurs unités de climatisation 20, les flux d'air dans cette enceinte 22 étant orientés par les ventilateurs tangentiels.It will be noted that the enclosure 22 is for example common to several air conditioning units 20, the air flows in this chamber 22 being oriented by the tangential fans.

Chaque unité de climatisation 20 comporte également un échangeur de chaleur 32, relié au circuit de circulation 16, propre à échanger des calories entre le liquide caloporteur et l'air circulant dans l'enceinte 22. Ainsi, les conduites 18 communiquent avec cet échangeur de chaleur 32. Un tel échangeur de chaleur 32 est classique et ne sera donc pas décrit davantage. Avantageusement, chaque échangeur de chaleur 32 présente des dimensions réduites.Each air conditioning unit 20 also comprises a heat exchanger 32, connected to the circulation circuit 16, suitable for exchanging calories between the coolant and the air circulating in the chamber 22. Thus, the lines 18 communicate with this heat exchanger. 32. Such a heat exchanger 32 is conventional and will not be described further. Advantageously, each heat exchanger 32 has reduced dimensions.

Similarly, the ducts 18 passing through the heat exchanger 32 are housed at the level of the floor. floor, especially under the floor panel 28.

Le dispositif de climatisation 10 comporte par ailleurs une unité de contrôle 34, notamment propre à commander les moyens centraux 14 de conditionnement pour contrôler la température du liquide caloporteur.The air conditioning device 10 furthermore comprises a control unit 34, in particular capable of controlling the central conditioning means 14 for controlling the temperature of the coolant.

En variante, ou de manière complémentaire, l'unité de contrôle 34 est propre à commander chaque organe de ventilation 30 pour contrôler le flux d'air circulant dans l'enceinte 22 de l'unité de climatisation 20 correspondante. Par exemple, les organes de ventilation 30 sont commandées individuellement, ou en variante par groupes.Alternatively, or in a complementary manner, the control unit 34 is able to control each ventilation member 30 to control the flow of air flowing in the chamber 22 of the corresponding air conditioning unit 20. For example, the ventilation members 30 are controlled individually, or alternatively in groups.

Ainsi, l'unité de contrôle 34 permet de contrôler la température à proximité de chacune des unités de climatisation 20, par exemple de manière localement différentiée, lorsque les flux d'air circulant dans les unités de climatisation 20 sont différents.Thus, the control unit 34 makes it possible to control the temperature close to each of the air conditioning units 20, for example in a locally differentiated manner, when the airflows circulating in the air conditioning units 20 are different.

Avantageusement, le dispositif de climatisation 10 comporte au moins un capteur de mesure de température 36 agencé à proximité de chaque unité de climatisation 20. L'unité de contrôle 34 est alors propre à commander l'organe de ventilation 30 de chaque unité de climatisation 20 pour contrôler le flux d'air circulant dans l'enceinte 22 de cette unité de climatisation 20, en fonction de la température mesurée par le capteur de mesure 36 correspondant à proximité de cette unité de climatisation 20. De tels capteurs de température permettent notamment de traiter différemment la climatisation de l'air d'un côté ensoleillé de la salle 12 par rapport à un côté situé à l'ombre.Advantageously, the air conditioning device 10 comprises at least one temperature measurement sensor 36 arranged close to each air conditioning unit 20. The control unit 34 is then able to control the ventilation member 30 of each air conditioning unit 20 to control the flow of air flowing in the chamber 22 of this air conditioning unit 20, as a function of the temperature measured by the corresponding measurement sensor 36 near this air conditioning unit 20. Such sensors of In particular, the temperature can be used to treat air conditioning on a sunny side of the room 12 differently than on a shadow side.

En variante, ou de manière complémentaire, le dispositif de climatisation 10 comporte des moyens 38 de détection d'une densité de passagers à proximité de chaque unité de climatisation 20. L'unité de contrôle 34 est alors propre à commander l'organe de ventilation 30 de chaque unité de climatisation 20 pour contrôler le flux d'air circulant dans l'enceinte 22 de cette unité de climatisation 20, en fonction de la densité de passagers détectée à proximité de cette unité de climatisation 20.Alternatively, or in a complementary manner, the air conditioning device 10 comprises means 38 for detecting a density of passengers near each air conditioning unit 20. The control unit 34 is then able to control the ventilation member 30 of each air conditioning unit 20 to control the flow of air flowing in the chamber 22 of this air conditioning unit 20, depending on the density of passengers detected near this air conditioning unit 20.

Les moyens de détection de densité 38 comportent par exemple au moins une caméra, et une unité informatique reliée à la caméra, propre à effectuer une analyse d'image permettant de déterminer la densité de passagers. Une telle analyse d'image est connue dans l'état de la technique, et ne sera donc pas décrite en détail. La caméra est par exemple une caméra grand-angle, agencée au plafond de la salle 12.The density detection means 38 comprise for example at least one camera, and a computer unit connected to the camera, capable of performing an image analysis to determine the density of passengers. Such an image analysis is known in the state of the art, and therefore will not be described in detail. The camera is for example a wide-angle camera, arranged on the ceiling of the room 12.

En variante, ou de manière complémentaire, le dispositif de climatisation 10 comprend au moins une interface de commande de l'unité de contrôle 34, permettant à au moins un passager de commander l'unité de contrôle 34, afin de contrôler la température du liquide caloporteur, et/ou de commander au moins l'un des organes de ventilation 30 pour contrôler le flux d'air circulant dans l'enceinte 22 de l'unité de climatisation 20 correspondante, à proximité de ce passager. Une telle interface de commande permet aux utilisateurs de modifier la température de l'air dans le cas où celle-ci leur semble inconfortable. Ainsi, de préférence, l'interface de commande est prioritaire sur les autres informations (densité de passagers, température détectée, etc.) utilisées par l'unité de contrôle 34 pour décider de la température.Alternatively, or in a complementary manner, the air conditioning device 10 comprises at least one control interface of the control unit 34, allowing at least one passenger to control the control unit 34, in order to control the temperature of the liquid coolant, and / or control at least one of the ventilation members 30 to control the flow of air flowing in the chamber 22 of the corresponding air conditioning unit 20, near this passenger. Such a control interface allows users to change the air temperature in case it seems uncomfortable. Thus, preferably, the control interface has priority over the other information (passenger density, detected temperature, etc.) used by the control unit 34 to decide the temperature.

Avantageusement l'interface de commande est un smartphone, par exemple le smartphone d'un passager, sur lequel a été installée une application permettant de communiquer avec l'unité de contrôle 34.Advantageously, the control interface is a smartphone, for example a passenger's smartphone, on which an application has been installed for communicating with the control unit 34.

Conformément à l'invention, les moyens centraux de conditionnement 12 conditionnent la température d'eau, qui circule dans le circuit 16 sous l'effet de la pompe, jusqu'aux unités de climatisation 20. Localement, dans chaque unité de climatisation 20, l'air est conditionné sous l'effet du ventilateur tangentiel 30 et de l'échangeur de chaleur 32 correspondants, au niveau du sol 28. En effet, l'air est aspiré depuis l'ouverture d'entrée 24 par le ventilateur tangentiel 30, vers l'échangeur de chaleur 32 où cet air échange de la chaleur avec le liquide circulant dans l'échangeur de chaleur, avant de ressortir par l'ouverture de sortie 26.According to the invention, the central conditioning means 12 condition the water temperature, which circulates in the circuit 16 under the effect of the pump, to the air conditioning units 20. Locally, in each air conditioning unit 20, the air is conditioned under the effect of the tangential fan 30 and the heat exchanger 32 corresponding to the ground 28. Indeed, the air is sucked from the inlet opening 24 by the tangential fan 30 to the heat exchanger 32 where this air exchanges heat with the liquid flowing in the heat exchanger, before exiting through the outlet opening 26.

Dans la salle 12, l'air est aspiré vers le haut sous l'effet de la présence de passagers, qui induisent une convection naturelle.In Room 12, the air is sucked upwards by the presence of passengers, which induce natural convection.

On notera que l'invention n'est pas limitée au mode de réalisation précédemment décrit, mais pourrait présenter diverses variantes complémentaires.Note that the invention is not limited to the embodiment described above, but could have various complementary variants.
