Definitions

  • the present invention relates to an air treatment module intended for the production of an air treatment installation, intended for the ventilation and air conditioning of a plurality of rooms.
  • An installation of a first type comprises a single air handling unit housed in a technical room and serving in parallel, by a network of branched ducts, air outlets in the different rooms; the single air handling unit, partially supplied with fresh air, also carries out air recovery in each room, via another network of branched ducts leading to air suction outlets arranged in the different rooms.
  • An installation of the second type overcomes these drawbacks, in that it comprises in each room a clean fan coil, taking in air only in this room, apart from a supply of fresh air, and blowing no air only in this room, as described for example in US-A-3 384 155, however in the case of an installation apparently operating without fresh air; this solution is hygienic and lends itself to a great flexibility of adjustment according to the specific needs of the room considered in ventilation and air conditioning; it also makes it possible to dispense with any network of air transport ducts.
  • this second type of installation obliges the personnel responsible for maintenance to intervene room by room, in often uncomfortable conditions, whether the fan coil is placed in a light or in a false ceiling; sometimes, even, maintenance operations can make the room unusable for a while, as it can be the case for example for certain hospital rooms; the same applies to any leaks of heat transfer fluid or condensates, which can also cause damage to the equipment located in the rooms in which it occurs.
  • each air supply mouth comprises a thermostatic flap for orienting blown air as a function of the supply temperature, in a manner known in it -even.
  • a breakdown of an air treatment module or an intervention of maintenance of this module does not interrupt the ventilation and the air conditioning only in the room respectively associated, and this for a time which can be considerably shortened since it is possible to design the air treatment modules and arrange them in the technical room so that maintenance operations are facilitated, regardless of any aesthetic concerns and any requirement for setting up in an inhabited room; however, each module, intended to provide ventilation and air conditioning in a single room, can have a sufficiently small footprint to be changed easily and quickly in the event of damage.
  • the design of such an installation makes it possible to completely eliminate the branching or diameter modification connections of the sheaths, that is to say to simplify their production and their installation; all the sheaths can have the same constant diameter from one end to the other; this diameter, adapted to the air flow corresponding to a single room, can be relatively small so that despite the number of ducts, their crossing with pipes or electrical cables does not present of difficulty, even in passages such as false ceilings having a low height; the possibility of using sheaths of constant diameter, in any desired length, also provides significant savings.
  • the air treatment modules are identical, only their adjustment being individualized, which makes it easy and quickly interchangeable in the event of damage.
  • the air treatment modules can be grouped into a small volume battery inside the technical room, while offering optimal access possibilities for maintenance and repairs; the replacement, if necessary, of a damaged module by another module is particularly easy if, moreover, the means of support of the various modules are mutually independent and suitable for allowing a separation of each module from the other modules by a displacement in directions parallel to said planar lateral faces.
  • these flat lateral faces are vertical and the modules are mutually juxtaposed horizontally, which facilitates the connection of the ventilation and air conditioning means to energy supply means arranged horizontally, parallel to the battery of juxtaposed modules.
  • the support means for each module may advantageously include means for suspending this module, each module being suspended in a ceiling area of the technical room; thus, the battery of juxtaposed modules does not have any space on the ground and the modules can be arranged at breast height, that is to say in a position making them particularly accessible for maintenance operations;
  • the suspension means of each module are located in an upper peripheral zone of said module, directly above the center of gravity of the latter, and include vibration damping means, which makes it possible to limit maximum risk of transmission of vibrations to the ceiling of the technical room; in addition, the localized suspension facilitates, by an appropriate choice of the suspension means, the replacement of one module by another.
  • the fan motor is of a variable speed type and connected to the respective adjustable regulation means, to allow an adaptation of the air flow rate passing through each air treatment module then blown into the respective room as a function temperature regulation.
  • the installation comprising the modules according to the invention comprises means for supplying the air treatment modules with New air.
  • the fresh air supply means to include a fresh air duct common to all the air treatment modules.
  • the internal air circuit of each module can also be connected to the fresh air duct by respective connection means distinct from said air suction connection but located like it on a peripheral face of the module and comprising respective fresh air flow regulating means advantageously integrated into the module itself;
  • the means for regulating the flow of fresh air can be autonomous, or advantageously controlled by the adjustable regulation means specific to the corresponding air treatment module;
  • the fresh air duct advantageously runs in a ceiling area of the technical room, parallel to the battery of juxtaposed air treatment modules, which constitutes a rational and space-saving arrangement.
  • the ducts, inside the technical room, and the means of connection of the ventilation and air conditioning means to energy supply means are flexible at least locally, which facilitates the movement of a module of air treatment compared to the others without it being necessary to intervene beforehand to detach the ducts and said connection means, that is to say allows to dispense with direct access to the latter when the modules are juxtaposed and to arrange the modules as close as possible to the ceiling of the technical room when they are suspended according to the preferred embodiment of the invention described above; in addition, this helps to avoid the transmission of vibrations from a module to the ceiling of the technical room, and the installation comprising the modules according to the present invention thus remains particularly silent and discreet.
  • Figure 1 where we schematically illustrated three rooms 1, 2, 3 to ventilate and air condition, and a technical room 4 grouping the air treatment modules 5, 6, 7 respectively associated to these three rooms 1, 2, 3; naturally, this example is in no way limiting and the number of rooms capable of being air-conditioned from the same technical room, that is to say the number of air treatment modules grouped in this technical room, will generally be greater than 3, a single technical room being for example provided for grouping the air treatment modules corresponding to all the rooms on the same floor of a building.
  • Each of the rooms 1, 2, 3 is equipped, advantageously in a form integrated into a false ceiling, with at least one suction or return air intake 8, 9, 10 and with at least one blowing mouth air 11,12,13, the choice and optimal relative arrangement of which are within the scope of the normal skills of a person skilled in the art; preferably, when room 1, 2, 3 is equipped with a window 14, 15, 16, the air blowing mouth 11, 12, 13 is disposed between the air suction mouth 8, 9, 10 and this window 14, 15, 16, and chosen of a type comprising a thermostatic flap for orienting the blown air, controlled by the blowing temperature as illustrated for example with regard to the blowing mouth air 11, in Figure 5 to which reference will now be made.
  • FIG. 5 there is schematically illustrated at 17 a horizontal false ceiling, allowing to remain above it, that is to say between it and a ceiling tile not shown, an intermediate space 18 in which is disposed , above the air blowing mouth 11, an air inlet box 19 comprising a connector 20 for a duct 21 for transporting air (also visible in FIGS.
  • each of the other air blowing outlets 12, 13 is associated such a box serving for the connection of a respective air transport duct 22, 23 as well as with each outlet air intake 8, 9, 10 is associated with a similar box used to connect a respective air transport duct 24 (also visible in Figures 1 and 3), 25, 26; preferably, each of these sheath connection boxes is internally thermally and acoustically insulated.
  • the air blowing mouth 11, and like it the air blowing mouths 12, 13, is in the form of an extruded longitudinal section seen in cross section in Figure 5; if one continues to refer to the air blowing mouth 11, this profile 27 is arranged parallel to the window 14 and internally delimits, at its upper part, communicating directly with the box 19, a single longitudinal channel 28 which is subdivided downwards into three juxtaposed longitudinal channels 29, 30, 31; channel 29, closer to window 14, bends towards the latter from channel 28 while the other two channels 30 and 31, together offering a passage section greater than that of channel 29 and for example double that -ci, are bent in the direction of a distance from the window from their connection to channel 28; the channel 30 is immediately adjacent to the channel 29 and separated from the latter by a longitudinal partition 32 of the profile 27 and at the upper part of this partition 32 is articulated on the latter, around a longitudinal axis 33, a longitudinal flap 34 also in the form of a shaped extruded profile, as illustrated and easily conceivable by a person skilled in the art, so that
  • the different air transport ducts 21, 22, 23, 24, 25, 26 have a constant section, identical from one duct to the other, are flexible, and each of them can thus extend. continuously, without an intermediate connection, from the room in which the air intake or air supply mouth is respectively associated, to the technical room 4.
  • the air transport ducts 21 and 24 corresponding respectively to the air blowing mouth 11 and to the air suction mouth 8 of room 1 is connected respectively to an air supply fitting 35 and to an air suction fitting 36 of the air treatment module 5 associated with this room 1; similarly, the air transport ducts 22 and 25 respectively associated with the air blowing mouth 12 and the air suction mouth 9 of room 2 are connected inside the technical room 4 respectively to an air supply connection 37 and to an air suction connection 38 of the air treatment module 6 associated with room 2, and the air transport ducts 23 and 26 connected respectively to the mouth supply air 13 and to the air intake mouth 10 of room 3 are connected inside the technical room 4 respectively to a connection of supply air 39 and to an air suction connection 40 of the air treatment module 7 associated with room 3; there is no intercommunication, that is to say no mixture of air, between the different air transport ducts 21, 22, 23 connected to the air supply vents 11, 12, 13 corresponding to the different rooms, just as there is no communication, i.e. no air mixing
  • each of the modules 5, 6, 7 the air travels through an independent circuit from one module to the other, that is to say allowing no mixing of the air flowing the respective internal circuits of the various modules 5, 6, 7.
  • the internal circuit thus traversed by the air from the suction connection 36 to the blowing connection 35 has the general shape of a U, shown diagrammatically at 41, the air suction fittings 36, 38, 40 of the various modules 5, 6, 7 being turned upward as well as their air supply fittings 35, 37, 39; successively, during the course of the circuit 41, the air arriving through the connector 36 inside the module 5 passes through a filter 42 and a heat exchanger 43, heating or cooling this air, before being taken up by a motor fan 45 leading to the blowing connector 35 and ensuring both the suction of air through the mouth 8 in the room 1 and the blowing of this air back by the air blowing mouth 11; similarly, the air arriving in each of the modules 6 and 7 via the respective suction connection 38, 40 successively encounters, inside this module, a filter, a heat exchanger and a motor-fan before exiting by the respective blowing connector 37, 39, the modules 5, 6, 7 being identical in the case of the preferred embodiment of the invention
  • each of the modules 5, 6, 7 is in a form such that the various modules can be suspended, and juxtaposed in the same horizontal alignment 53 to which the pipe fresh air supply 46, then rectilinear, is advantageously parallel, while providing optimal access possibilities.
  • modules 5, 6, 7 will now be described with reference to FIGS. 2 and 3, which illustrate module 5, taking into account that modules 5 and 7 are identical to it, except for any differences in setting, as will appear below; the module 5 will be described in its suspension position, that is to say as illustrated in FIGS. 2 and 3.
  • the module 5 is in the form of a metal box, produced by assembling sheets which define on the one hand an external contour which will now be described, and on the other hand an internal contour which, defining the internal air circuit 41, is geometrically similar, at least approximately, to the external contour and will therefore not be described, being easily deducible from the external contour.
  • This external contour is characterized in particular by the presence of two flat lateral faces 54, 55, mutually parallel and perpendicular to the alignment 53 of the modules 5, 6, 7, which are juxtaposed two by two by these faces such as 54 and 55; to avoid direct contact of the sheet metal of the modules thus juxtaposed, the face 54 is provided with pads reported in projection 56, 57 and the face 55 is provided with pads reported in projection 58, 59, which buffers constitute shims maintaining a mutual spacing for example between the face 54 of the module 5 and a face of the module 7 corresponding to the face 55 and adjacent to the face 54 and between the face 55 and a face of module 6 corresponding to face 54 and adjacent to face 55; advantageously, the pads 56, 57, 58, 59 are made of a vibration-absorbing material, such as felt or rubber, and offering good sliding characteristics on the sheet, in order to facilitate the separation of a module from to the other modules by a movement which will be described later; for this purpose also, the respective positions of the buffers 56, 57 on the face 54
  • the module 5 is entirely located between the geometric planes (not shown) of its lateral faces 54 and 55.
  • the module 5 is further delimited by peripheral faces 60, 61, 62, 63, 64, 65 perpendicular to the faces 54 and 55 which they connect to each other and, in the example illustrated, planar although other shapes may also be suitable.
  • the peripheral faces 60 and 62 are horizontal and respectively constitute an upper peripheral face and a lower peripheral face 62 of the module 5; the peripheral face 61, which connects them, constitutes a front face having an obliquity of the order of a few degrees of angle relative to the vertical, the balance of its connection with the lower peripheral face 62 being set back relative to the vertical alignment of its connection with the upper face 60; the peripheral faces 63, 64, 65 also together define a front face of the module 5; the faces 63 and 65 are connected respectively to the lower face 62 and to the upper face 60 approximately according to the same plumb and have, with respect to the vertical, antagonistic obliquities, of the order of a few degrees of angle, such that '' they converge in the direction of a distance from the opposite front face 61; these two faces 63 and 65 are connected to each other by the face 64 which, taking into account a development of the face 65, in the direction of the height, greater than that of the face 63 and an obliquity of the faces 63 and
  • the sheet defining this upper face 60 is pierced with a cylindrical hole 67 of revolution around a vertical axis 66 and around which the air suction connection 36, tubular of revolution around the axis 66, is secured in a sealed manner with the sheet defining the upper peripheral face 60.
  • an upper cover 70 is provided, which advantageously is integral with the heat exchanger 43 and secured in a removable manner with the sheet metal constituting the upper peripheral face 60 of the module 5, above this face 60, to allow the heat exchanger 43 to be removed, if necessary, from the module 5 by simple vertical traction, upwards, on the cover 70 after separation of the latter relative to the sheet defining the upper peripheral face 60 of the module 5; for this purpose, the cover 70 advantageously carries, projecting upwards, that is to say towards
  • the upper cover 70 also serves as a passage for means for connecting the heat exchanger 43 to energy supply means; these energy supply means are illustrated in this example in the form of two pairs of pipes thus serving the heat exchangers of the different modules, and advantageously suspended in a ceiling area of the technical room 4, in a rectilinear, horizontal arrangement, parallel to the alignment 53, by reason of a cold water inlet pipe 72 and a cold water return pipe 73, connected to traditional refrigeration means and not shown, of a pipe d hot water inlet 74 and a hot water return pipe 75, connected to also traditional heating means and not shown, insofar as the heat exchanger 43 is of a type which also practices both the heating and the cooling of the air in the circuit 41 by exchange with a heat transfer fluid, namely water; it will be noted however that the heating of the air could be practiced by means of electric heating resistances, in which case the pipes 74 and 75 would be eliminated, as well as the heating means, and the electric heating resistances would be connected to a network of supply of electricity, not
  • the upper cover 70 is traversed vertically by four heat transfer fluid transport tubes, namely a water supply tube 76 hot, a tube 77 for hot water return, a tube 78 for cold water inlet and a tube 79 for cold water return; these four tubes, made of rigid material, bend horizontally immediately above the upper cover 70 and thus run along the upper face 60 of the module until the latter is connected with the front face 61, along the connector 36; at connection of the faces 60 and 61, the four tubes 76, 77, 78, 79 bend downward, vertically with regard to the two inlet tubes 78 and 76 and along the front face 61 with regard to the two return tubes 77 and 79, which then deflect vertically to present themselves parallel to the other two tubes 76 and 78, up to a level slightly higher than that of the lower face 62 of the module; the four tubes 76, 77, 78, 79 are rigidly connected, but easily removable
  • the two cold water transport tubes 78, 79 are provided a solenoid valve 80 as well as the two tubes 76, 77 for transporting hot water are provided with a solenoid valve 81; at a level lower than that of the solenoid valves 80 and 81, the tubes 76, 77, 78, 79 are connected, by quick couplings not shown, to a respective flexible tube 82, 83, 84, 85 itself connected in branch respectively on the hot water inlet pipe 74, the hot water return pipe 75, the cold water inlet pipe 72, the cold water return pipe 73.
  • the valves 80 and 81 consequently make it possible to regulate respectively the flow of cold water and the flow of hot water in the heat exchanger 43, in a regulated manner by adjustable means for regulating in temperature and preferably in flow of air of module 5, independent of the respective corresponding means of the other modules and incorporated in a housing 86 which, preferably, is carried integrally and not represented by one of the peripheral faces 60 to 65 of module 5, in a chosen location so that this box 86 is easily accessible in order to allow the regulation means to be adjusted while the module 5 is suspended and juxtaposed to other modules by its lateral faces 54 and 55; the valves 80 and 81 are connected to this box 86 by respective electrical conductors 87, 88 running along the peripheral faces of the module 5; alternatively, not shown, the housing 86 could be housed inside the module 5, one of the peripheral faces 60 to 65 of which would then have an access hatch to this housing 86, provided with a removable cover , easily conceivable by a A person skilled in the art, or else being structurally dissociated from module

  • the motor-fan 45 is advantageously a variable speed fan motor, connected by conductors 100 to the adjustable means for regulating the module 5 in temperature and air flow, incorporated in the housing 86; in a simplified version, the variable speed motor fan could be replaced by a fixed speed motor fan, preferably arranged in the same way.
