Definitions

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.
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.
Such an air conditioning device is particularly bulky.
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.
the invention is intended to overcome these disadvantages, by providing a space-saving air conditioning device for comfortable air conditioning diffusion.
the central means according to the invention are intended for liquid conditioning, and are therefore less bulky than air conditioning means.
liquid circulation lines for the circuit according to the invention are less bulky than air circulation lines.
the air conditioning device according to the invention is less bulky than an air conditioning device of the state of the art.
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.
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.
the coolant is water, especially glycol water.
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.
the air conditioning device 10 also comprises at least one air conditioning unit 20, housed in one of the rooms 12.
Each room 12 preferably houses a plurality of air conditioning units 20.
the air conditioning device 10 may comprise air conditioning units 20 housed in different rooms.
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.
each air inlet opening 24 opens into a sub-frame or down a side wall of the room.
the outlet openings 26 are formed in a floor panel 28, partially delimiting each chamber 22.
the inlet and outlet openings 24 are all formed in the floor panel 28 partially delimiting each chamber 22.
Each air conditioning unit 20 further comprises a ventilation member 30, housed in the chamber 22, adapted to circulate air in the chamber 22 from the inlet opening 24 to the outlet opening 26.
the ventilation member 30 is therefore housed at ground level, in particular under the floor panel 28.
the ventilation member 30 is a tangential fan.
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.
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.
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.
the lines 18 communicate with this heat exchanger. 32.
a heat exchanger 32 is conventional and will not be described further.
each heat exchanger 32 has reduced dimensions.
the heat exchanger 32 is housed at ground level, close to the ventilation member 30, in particular under the floor panel 28. 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.
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.
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.
the ventilation members 30 are controlled individually, or alternatively in groups.
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.
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 temperature sensors make it possible in particular to treat air conditioning differently on a sunny side of room 12 relative to a dark side.
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.
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.
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.
a control interface allows users to modify the air temperature in the case where it seems to them uncomfortable.
the control interface has priority over the other information (passenger density, detected temperature, etc.) used by the control unit 34 to decide the temperature.
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.
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.
