- Said room 2 or said confined space furthermore advantageously comprises a floor 5.
- Said side walls 4, said floor 5 and said ceiling 3 preferentially delimit said room 2 or said confined space and more precisely the interior space of the latter or of the latter.
- room 2 or said confined space further comprises corners 6 separating said side walls 4.
- Said room 2 or said confined space may consist of any enclosed or closed volume within a building or an immobile or mobile structure, such as a vehicle (train or plane for example).
- Said room 2 can be intended to accommodate individuals (staff, customers, etc.) and/or animals, as well as computer installations, for example (servers in particular), or even can be intended for the storage of products (foodstuffs, raw materials, processed products, etc.).
- Said confined space can be constituted by any closed or closed volume, within a mobile or immobile structure, which volume is generally not intended to accommodate personnel for a prolonged period, such as a tank, a storage place, a tank, a warehouse (the definition of a confined space may in some cases overlap with that of a room), a vault, a ship's hold, a silo, a tunnel, etc.
- Said room 2 or said confined space may moreover have a variable ceiling height as in the case of a theater or cinema in an amphitheater (FIGS. 11 and 12).
- Said ventilation system 1 is therefore preferably intended to equip said room 2 or said confined space to ventilate the latter or the latter.
- said room 2 or said confined space can be formed by any closed volume to be ventilated, said closed volume possibly being partially or completely closed.
- the invention further relates, according to a second aspect, to a ventilated room or confined space 2 comprising at least one ceiling 3, said room 2 or said confined space being equipped with a ventilation system 1 as described above and below.
- the invention also relates, according to a third aspect, to a building or a mobile structure (for example a vehicle, such as a road or rail vehicle, a ship or an aircraft) comprising at least one ventilated room or confined space ) 2 as described above and below.

- the ventilation system 1 advantageously forms a gas extraction and distribution system.
- the gas is in particular air, i.e. a mixture comprising mainly nitrogen and oxygen (as well as carbon dioxide, argon etc. in smaller quantities), but it can also comprise, or be formed by, steam, for example steam.
- the gas can however be made up of other components, and for example the gas mainly comprises oxygen, or else mainly one or more carbon oxides, or any gaseous compound in particular at room temperature (between 10 and 30°C for example) .
- the gas is advantageously mainly present in a free space of said room 2 or of said confined space, that is to say the space delimited by said side walls 4, floor 5 and ceiling 3 and not by other walls or partitions. Arrows that do not refer to any number in the figures generally represent localized airflow.
- the ventilation system 1 is advantageously designed to renew the gas, and in particular the air, within a room 2 or a confined space, that is to say on the one hand to extract the gas already present within said room 2 or said confined space outside the latter or the latter (or at least outside the free space of the latter or the latter), by means of the suction device 8, and on the other hand introducing ("new") gas passed through the ventilation system 1, by means of the blowing device 7.
- said "new" gas has been treated by said ventilation system 1 (for example by a treatment device included in said system 1) and/or comes from outside the room 2 or the confined space, so that it is formed of gas exterior and/or treated gas, it being understood that in all cases said new gas passes through said ventilation system 1.
- Said blowing and suction devices 7, 8 are preferably designed to operate continuously, the gas successively passing through the blowing device 7, the room 2 or the confined space, the suction device 8, and then possibly the outside the room 2 (or the confined space) and/or again the blowing device 7, as will be seen below.
- Said blowing device 7 is therefore preferably designed to blow gas into room 2 or the confined space, while said suction device 8 is advantageously designed to draw gas from said room 2 or said confined space.
- the suction device 8 comprises a plurality of suction mouths 9, 10, 11.
- the blowing device 7 comprises a plurality of blowing mouths 12, 13, 14.
- mouth must be taken here in its broadest sense, so that it can designate all kinds of openings, orifices, pores or others, regardless of their dimensions and configuration.
- Each of said openings 9, 10, 11, 12, 13, 14 can thus be formed, for example, by one or more orifice(s) or opening(s), in the form, for example, of perforations made through a sheet, or by the through pores of a wall made of rigid, flexible or flaccid porous material, or even by the interstices existing between the threads or fibers of a woven or non-woven, textile or metallic material, for example a textile fabric, a metallic fabric or a combination of textile and metallic fabrics.
- Said suction mouths 9, 10, 11 are distributed, for example in layers, one below the other, in a substantially vertical direction (shown by the Z axis in FIGS. 1 to 3 and 11).

- the intermediate suction mouths 12 are, according to a particular embodiment, distributed in a substantially regular manner, in particular in the vertical direction and/or in the horizontal plane. It is of course possible that certain suction mouths 9, 10, 11 are at the same height (that is to say in the same horizontal plane), but there are preferably necessarily suction mouths 9, 10, 11 distributed vertically one above the other, with a gap relative to each other in the horizontal plane preferably less than 10 cm, more preferably less than 5 cm, more preferably still less than 3 cm, more preferably still substantially zero. Examples of horizontal planes are shown in Figures 1, 2 and 12 by the X and Y axes (which are therefore advantageously substantially perpendicular to the Z axis).
- the distance between said high 9 and low 10 suction vents is greater than at least half the height under the ceiling 3 of said room 2 or of said confined space.
- Said ceiling height is measured locally, that is to say at the location where said suction device 8 is located.
- the distance between said high 9 and low 10 suction vents is greater than 80%, preferably is greater than 90% of the height under ceiling 3 of said room 2 or of said confined space, and more preferably is almost equal to or equal to the height under ceiling 3 of said room 2 or of said confined space.

- a means of depollution, decontamination and/or deodorization of the gas for example a particle filter, an antivirus filter and/or an antibacterial filter, such as a UV filter, or even a carbon filter,
- a means for regulating the physical parameters of the gas for example a means for regulating the hygrometry and/or a means for regulating the temperature of the gas, such as a means for heating and/or cooling the gas, or another dehumidifier, and/or
- a means of homogenizing the gas for example a mixer.
- the blowing device 7 and the suction device 8 are designed for respectively collecting and ejecting gas outside said room 2 or said confined space (and preferably outside the ventilation system 1), for example air coming from outside (a building or a particular vehicle).
- the exterior is preferably located outside the room 2 or the confined space and outside the ventilation system 1.
- the ventilation system 1 then advantageously comprises one or more gas inlets 26 making it possible to collect gas from the outside. to the blower device 11, and one or more gas outlets 27 for ejecting gas from the suction device 8 to the outside.
- Said gas treatment means 20 can be designed to treat gas coming from outside said room 2 or said confined space.
- Said intermediate pipe 19 can thus optionally be connected to said or at least one of said gas inlet(s) 26 (as illustrated in FIG. 12, bottom right) and/or to said or at least one of said evacuation(s) of gas 27.
- the gas coming from the blower device 7 can come entirely from the gas sucked in by the suction device 8, or else it can come entirely from outside said room 2 or said confined space and not from the suction device 8 which then rejects all the gas outside the room 2 or the confined space, or else it can come partly from the suction device 8 and partly from outside of said room 2 or said confined space without first passing through said suction device 8.
- the suction device 8 is designed to be arranged away from the walls 4 of the room 2 or of the confined space, by example more than one meter from each wall 4. It can then advantageously extend from the floor 5 to the ceiling 3 without contact with one of the walls 4.
- the suction device 8 is placed in the center of room 2 or confined space.
- the invention also relates, according to a fourth aspect, to a method for ventilating a room 2 or a confined space provided with a ceiling 3, this method preferably being designed to be implemented by means of the ventilation system 1 mentioned above.
- the above description concerning the ventilation system 1 therefore also applies to the ventilation method, and vice versa.
- the method comprises at least
- suction stage being carried out via a plurality of suction mouths 9, 10, 11 of a suction device 8 (preferably mentioned above), the suction mouths 9, 10, 11 being distributed one below the other in a substantially vertical direction, said suction mouths 9, 10, 11 comprising at least one suction mouth high 9 and a low suction mouth 10, as well as intermediate suction mouths 11 located between said high suction mouths 9 and low 10, the distance between said high suction mouths 9 and low 10 being greater than at least half the height under ceiling 3 of said room 2 or of said confined space.
- blowing step is preferably carried out using said blowing device 7, and said suction step is advantageously carried out using said suction device 8.
- the ventilation method advantageously comprises, before (and upstream of) said blowing step, a gas treatment step, preferably using the gas treatment means 20, the gas treatment step having preferably takes place after (and downstream of) the suction step.
- the blowing step is carried out via a plurality of blowing mouths 12, 13, 14 of a blowing device 7 (preferably the one mentioned above).
- the blowing mouths 12, 13, 14 preferably comprise at least one high blowing mouth 12 and one low blowing mouth 13, as well as intermediate blowing mouths 14 located between said high blowing mouths 12 and low blowing 13, the distance between said high 12 and low 13 air vents being greater than at least half the height under the ceiling 3 of said room 2 or of said confined space.
- the suction device 8 comprises at least one suction pipe extending substantially along a direction of longitudinal extension intended to be placed substantially vertically, said suction pipe being provided with said suction mouths 9, 10, 11.
- the blowing device 7 comprises at least one blowing pipe extending substantially along a direction of longitudinal extension intended to be placed substantially vertical, said blowing pipe being provided with said blowing mouths 12, 13, 14.
- Said suction pipe 8 and/or said blowing pipe 7 has a (respective) cross-section which is substantially curved or at least partly curved .
- suction mouths 9, 10, 11 are distributed over said suction pipe so as to allow radial suction of the gas from room 2 or from the confined space and/or said blowing mouths 12, 13, 14 are distributed over said supply pipe so as to give a radial distribution to the gas emitted from the latter (within room 2 or the confined space).
- the ventilation system 1 of the invention makes it possible to carry out a faster and more complete renewal of the gas contained in a room 2 or a confined space, which can be particularly useful in the context of a surgical operation for example, in order to reduce the risk of contamination, or in a more general setting, in particular a classroom, a living room, an office, an open space, a meeting room, a room in a commercial premises (store), a cinema or performance hall (theater), a cistern, a silo, a hold, a tank, a train car, or even an airplane cabin (or any other suitable closed volume).
- the ventilation system 1 of the invention is therefore particularly intended for the problem of room 2 or confined space ventilation, which encompasses health safety issues related to the contamination of microorganisms (pandemic, contamination in hospitals, etc. .), pollution (fine particles, etc.), the physical safety of goods and living beings, the general well-being of people (air conditioning, heating, etc.), and energy optimization.
- the invention finds its industrial application in the design, manufacture and implementation of ventilation systems.
