    [0001] The technical sector of the present invention is that of controlled mechanical ventilation devices for buildings and especially in individual dwellings. Controlled mechanical ventilation, also referred to as VMC, generally includes a duct system providing for air circulation in a building. The renewal of the air is thus controlled to ensure a minimum air quality. The air extracted from certain parts is evacuated to the outside. Air blowing into the building can be done naturally through openings or forced through another conduit network. A technical problem is that the renewal of the air may involve the blowing of fresh air at low temperatures inside the building, which then requires increasing the heating of the building. The new standards for residential housing thus require controlled mechanical ventilation to meet the constraints of both air renewal and energy saving. These constraints come in particular in the specifications of the 20 so-called low energy buildings, also designated by the BBC. Humidity-controlled extraction vents allow, depending on the humidity level in the air, to favor or limit the extraction of air. Such regulation must, however, be put in place on each extraction mouth. In particular, the complex hygrothermal vents imply a relatively high cost for the controlled mechanical ventilation device. The present invention aims to overcome the disadvantages of the prior art by providing a controlled mechanical ventilation device whose structure is simplified while meeting the current constraints of air renewal and energy saving. This objective is achieved by means of a controlled mechanical ventilation device comprising an outward evacuation duct connected to a box and extraction ducts connected on the one hand to the box and opening each other in one of the chambers. parts to 3036465 2 ventilate, characterized in that it comprises a plurality of fans controlled by at least one control system according to the data provided by a plurality of sensors for analyzing the composition of the air, each fan being associated to one of the extraction ducts and controlled according to at least one of the sensors disposed in the extraction duct with which this fan is associated. According to one particularity of the invention, the sensors for analyzing the composition of the air are sensors for the level of CO2 in the air. According to another feature of the invention, the sensors for analyzing the composition of the air are sensors of the hygrometry of the air. According to another particularity of the invention, the control system 15 controls each fan at a first stored minimum flow specific to each room to which is added a second stored rate weighted by a first multiplier coefficient, as a function of the humidity measured in this room, a maximum stored hygrometry and a stored minimum hygrometry. According to another particularity of the invention, the first multiplying coefficient is calculated according to the formula: (Hm-H1) / (H2-H1) in which: 25 Hm is the measured hygrometry, H1 is the minimum hygrometry and H2 is the maximum hygrometry. According to another feature, the controlled mechanical ventilation device according to the invention comprises an outdoor temperature sensor, said second rate being calculated by the control system as a function of a third memorized flow rate, to which is added a fourth weighted memorized flow rate. by a second multiplying coefficient depending on the measured outdoor temperature, a stored maximum outside temperature and a stored minimum outside temperature. According to another particularity of the invention, the second multiplying coefficient is calculated according to the formula: ## EQU1 ## in which: Tm is the measured outside temperature, Tl is the minimum outside temperature and T2 is the maximum outside temperature. According to another particularity of the invention, the control system stores a table for determining said minimum external temperature and maximum outside temperature and said minimum hygrometry and maximum hygrometry, as a function of a geographical location with respect to stored geographical areas cut in half. depending on their temperature and hygrometry variations. Another object of the invention resides in the fact that the box for the VMC device comprises an evacuation channel constituting part of the exhaust duct and a plurality of extraction ducts each constituting in part one of the ducts. extraction, each of the fans being disposed in one of the extraction channels of the box. According to a feature of the invention, each extraction channel comprises a location for the implantation of one of the fans across said extraction channel, each location being associated with an access passage made in the box. According to another feature of the invention, each sensor is disposed in the exhaust channel of the fan with which this sensor is associated, each sensor being arranged projecting through an opening made in the channel and partially covered by an inner wall of deflection of the air.
    [0002] According to another feature of the invention, the extraction channels are bent to come tangentially facing the discharge channel. According to another particularity of the invention, the extraction channels terminate in extraction orifices arranged side by side and in front of the discharge channel, the section of the extraction channels being reduced towards the orifices of extraction. According to another feature of the invention, the extraction orifices each have at least one internal separation wall with at least one of the adjacent channels, said internal walls being inclined at a given angle towards a central axis in each channel. extraction.
    [0003] According to another feature of the invention, said angle is between 10 degrees and 15 degrees. According to another feature of the invention, said angle is greater than or equal to 12 degrees. A first advantage is that the VMC device is of less complex structure and thus has a reduced cost, all of which can meet the requirements of air renewal and energy saving. Another advantage of the present invention is that the VMC device is more reactive due to a reduced reaction time with respect to air quality and a more precisely controlled extract air flow rate. Another advantage of the present invention is also that the extraction of air can be controlled according to the hygrometry rate or as a function of the CO2 level in the air.
    [0004] Another advantage of the present invention is that it makes it possible to take into consideration the environmental climatic conditions. The outside temperature can in particular be measured and taken into account for the extraction control, instantaneously.
    [0005] An advantage of the present invention is also that it makes it possible to adjust the extraction control with respect to the calculated required flow rate to compensate for the pressure drops of the extraction duct network. Other characteristics, advantages and details of the invention will be better understood on reading the additional description which will follow of embodiments given by way of example in relation to drawings in which: FIG. schematically a controlled mechanical ventilation device installed in a building; - Figure 2 shows schematically a controlled mechanical ventilation device; FIG. 3 schematically represents a control system taking into account a geographical division stored in memory; FIG. 4 represents an example of control of the extraction rate in a duct by a fan; FIG. 5 represents a view from above of a box for a controlled mechanical ventilation device; - Figure 6 shows a sectional view of a portion of the box where is installed a sensor for controlling the associated fan; Figure 7 shows a perspective view showing the evacuation channel of the box; - Figure 8 shows a sectional view of the evacuation channel of the box. The invention will now be described in more detail. Figure 1 schematically shows a mechanical ventilation device controlled the installed in a building. The controlled mechanical ventilation device comprises an exhaust duct 2 to the outside connected to a box 3. Exhaust ducts 4a, 4b and 4c are connected on the one hand to the box 3 and open on the other hand each in one of the rooms to be ventilated 5a, 5b and 5c. The number of extraction ducts is not limiting. The air is blown into one or more rooms 10. The air 25 circulates for example between the various parts 10, 11, 12, 5a, 5b and 5c. The rooms in which the air is extracted are for example the kitchen, the bathroom or the toilets. Extraction can also be provided in other rooms. The air can also be blown through a second insufflation network, not shown. The extraction ducts open through extraction openings 23a, 23b and 23c, for example in the form of a simple opening grille or in the form of an element for directing the flow of extracted air. . Sealing devices 22a, 22b, 22c connect the extraction ducts 4a, 4b and 4c to the extraction openings 23a, 23b and 23c. Sealing devices 20a, 20b, 20c connect the extraction ducts 4a, 4b and 4c to the box 3. The box here has a closure plate 21 that can be removed to adapt to a different configuration for a other building.
    [0006] The mechanical ventilation device is controlled by a control system 7 which controls the rotational speeds of the various fans. The control system 7 includes, for example, a power supply for supplying power to a driver card and a power stage. The control system 7 will be described in more detail with reference to FIG. 3. An external sensor 9 is connected to the control system 7. This sensor is for example an atmospheric pressure sensor, a humidity sensor, a sensor temperature or other type of sensor providing signals representative of the external climatic conditions. Several external sensors connected to the control system can also be provided.
    [0007] Figure 2 schematically shows a controlled mechanical ventilation device 1 alone. The controlled mechanical ventilation device 1 comprises four extraction ducts 4a, 4b, 4c and 4d each terminating in an extraction opening 23a, 23b, 23c and 23d. The number of extraction ducts is not limiting. Each extraction duct is associated with a fan and a sensor. Each fan 6a, 6b, 6c and 6d, respectively, is disposed across its own extraction duct 4a, 4b, 4c and 4d and thus controls the flow of air in this extraction duct. Each fan is arranged in the extraction duct with which it is associated. An air composition analysis sensor 8a, 8b, 8c or 8d is disposed in each extraction duct. The signals supplied by each air composition analysis sensor 35 are processed by the control system 7 to generate the fan control control in the same exhaust duct. The control of each fan can also be determined according to several signals provided by several sensors arranged in the same extraction duct. It can also provide two or a plurality of fans arranged in the same channel. Each channel can thus accommodate a fan or a plurality of fans controlled according to the data provided by one or more sensors arranged in this channel. It is also possible to remove the fan or fans from an unused channel, this channel for example being plugged by a blanking plate. The sensors for analyzing the composition of the air are, for example, carbon dioxide (CO2) sensors in the air or sensors for the hygrometry of the air.
    [0008] The sensors inside the extraction ducts are, for example, hygrometry sensors. The control system 7 can then drive each fan 6a, 6b, 6c and 6d at a first stored minimum flow D301 specific to each room, which is added a second stored rate D302 weighted by a first memorized multiplier coefficient D303. This first stored multiplier coefficient D303 is, for example, a function of the hygrometry rate measured in the room and stored in a memory space D304. The first multiplier coefficient corresponds for example to a measurement relative to a maximum hygrometry and a minimum hygrometry. The first multiplier coefficient is for example calculated according to the formula: (Hm-H1) / (H2-H1) in which: Hm is the measured hygrometry, H1 is the minimum hygrometry and H2 is the maximum hygrometry. Each room can be ventilated independently of the other 35 rooms. A minimum flow is left in each room. So if the kitchen is used but not the bathroom, the air extraction in the kitchen can be favored while the air extraction in the bathroom can be left to the minimum. The average humidity of each geographical region can be taken into account in particular by setting the hygrometry threshold high H2 and the hygrometry threshold low Hl.
    [0009] Furthermore, the hygrometry sensor in the extraction duct immediately provides the data representative of the hygrometry, these data being processed in real time to adapt in real time the extraction rate D305.
    [0010] The control of each fan is for example carried out by a control voltage, while information representative of the speed of rotation of the fan is supplied back to the control system. Thus the flow can be adjusted precisely and in real time.
    [0011] Advantageously, the pressure drops in each extraction duct are compensated because of the precise adjustment of the extracted air flow rate in each extraction duct. The settings are both accurate and responsive, saving energy is significant.
    [0012] The climatic conditions can also be taken into account to control each fan. The data generated by the external sensor 9 are for example processed for calculating the second rate D302 intended to be weighted by the first coefficient D303.
    [0013] The control system 7 determines for example the second rate D302 as a function of a third stored rate D306 to which is added a fourth stored rate D307 weighted by a second coefficient D308. This second coefficient D308 is, for example, calculated as a function of the signals supplied by the external sensor or sensors. The outdoor sensor 9 is for example a temperature sensor providing signals representative of the outside temperature. The second multiplier coefficient D308 is then a function of the measured outdoor temperature. This second coefficient can in particular be calculated in real time according to an instantaneous measurement of the temperature. The measured temperature is for example considered as a function of a maximum temperature and a minimum temperature according to the geographical region. The second multiplier coefficient is for example calculated according to the formula: (Tm-Tl) / (T2-T1) in which: Tm is the measured outside temperature, Tl is the minimum outside temperature and T2 is the maximum outside temperature.
    [0014] Thus climatic conditions can be considered relative to the geographical area considered. The average temperature of each geographical region can notably be taken into account by adjusting the low temperature threshold T1 and the high temperature threshold T2.
    [0015] Furthermore, depending on the activity inside the building, the external climatic conditions may or may not have an influence on the adjustment of the airflows. The sensors inside the extraction ducts can also be sensors of the CO2 level. The control system 7 can then drive each fan 6a, 6b, 6c and 6d at a first stored minimum flow specific to each room, to which is added a second stored rate weighted by a first multiplier coefficient determined according to the measured CO2 level. in the room. This first multiplier coefficient is, for example, equal to 1 if a normal CO2 level is stored and reset after a given time delay or after the CO2 level has returned to a level lower than or equal to a low level. stored.
    [0016] FIG. 3 represents an example of a control system taking into account a geographical division stored in memory for controlling the controlled mechanical ventilation device. The control system 7 includes a power supply 401 supplying power to a power stage 402 generating the control voltages of the fans and to a low power circuit performing the data processing. The low power circuit comprises, for example, a computing and processing component 403 such as a processor connected to a control and communication bus 407. The bus 407 is for example connected to a memory component 406 and to a signal receiving interface component 404 provided by the different sensors. The bus is also connected to a component 405 comprising setting devices such as jumpers. The control system 7 stores, for example, a table 400 for determining the settings for processing the measurements made by certain sensors as a function of the geographical area. The geographical division takes into account, for example, the minimum outside temperature and the maximum outside temperature as well as the minimum hygrometry and the maximum hygrometry. These extremums are for example dependent on the season considered during the year. Extremes are for example obtained by averaging over the last twenty years. For example, it is possible to provide ten different positions for jumpers 405 on the electronic card of the control system to adjust the command according to one of the geographical locations R1 to R10 stored. A maximum hygrometry H2 or H2 'and a minimum hygrometry H1 or H1' are for example associated with each stored geographical area R1 to R10. A maximum temperature T2 or T2 'and a minimum temperature Tl or Ti' are for example associated with each stored geographical area R1 to R10. For the sake of clarity, the table is not represented with all its values. The signals representative of the hygrometry provided by the sensors inside the extraction ducts are for example read and processed, the hygrometry data then being stored in memory spaces D304, D314, D324 and D334 in real time. . Each program can perform read and write accesses in memory. The signals representative of the external temperature 3036465 11 provided by the external sensor are for example read and processed, the outside temperature data then being stored in a memory space Tm in real time. The fan speed settings D305, D315, D325 and D335 are set by one or more programs stored in memory and executed when the control system is activated. These setpoints D305, D315, D325 and D335 are then transformed into control signals by the power stage 402. Each setpoint can be developed sequentially or in parallel by one or more programs. A first program P350 reads, for example, the data in the table 400 as a function of the positioning of the jumpers 405 and the data D304 representative of the measured hygrometry to calculate and memorize the first coefficient D303. The first program P350 then calculates the setpoint D305 as a function of the memorized minimum flow rate D301 to which is added a second stored rate D302 weighted by the first memorized coefficient D303.
    [0017] A stored second program P351 for example performs a read access in the table 400 according to the positioning of the jumpers 405 and also reads the data Tm representative of the measured outside temperature to calculate and memorize the second coefficient D308. The second program P351 then calculates the second rate D302 corresponding to a third stored rate D306 to which is added a fourth stored rate D307 weighted by the second coefficient D308. By setting the second flow D302, the second program allows a modification of the set point D305 as a function of the outside temperature. Various parameters can thus be taken into consideration in developing the fan instructions. The different parameters taken into account can also have different weights. An extraction rate may for example increase while the outside temperature drops due to variations of other parameters taken into consideration. The increase in temperature can, for example, favor the extraction of air to optimize the quality of the air by minimizing the energy expenditure for heating the building. It is also possible to provide a control loop 5 for controlling the fans according to their set point. FIG. 4 schematically represents an example of control of the extraction rate Qv of a fan according to the present invention. The flow Qv can vary between a minimum flow rate Qvl and a maximum flow rate Qv2a, Qv2b or Qv2c. The air quality is represented here according to a measurement performed inside the building, relative to a high threshold HR2 and a low threshold HR1. The interior sensors may for example be of the hygrometry sensor type or the sensor of the CO2 level. In the example of Figure 4, a hygrometry sensor is used to adjust the flow control of a fan. When the hygrometry is lower than or equal to the low threshold HR1, the flow is controlled at least at Qvl.
    [0018] When the hygrometry is greater than or equal to the high threshold HR2, the flow rate is controlled to the maximum. This maximum rate Qv2a, Qv2b or Qv2c can be adjustable, as detailed later. Between the low threshold HR1 and the high threshold HR2 the flow control is adjusted for example according to a linear function.
    [0019] An external sensor makes it possible to refine the flow control, for each fan, taking into account the external conditions. Several external sensors can also be used. The maximum flow rate can in particular be set at Qv2a, Qv2c or at a rate Qv2b between Qv2a and Qv2c. As shown in the graph, we have: Qvl <Qv2c <Qv2b <Qv2a The setting of the maximum flow rate is here a function of the temperature T, the external sensor being a temperature sensor. Sensors of different types can also be used to set the maximum flow Qv2. External sensors, of the atmospheric pressure sensor type, humidity rate sensor, sunshine rate sensor or other sensors providing data on the external climatic conditions, may for example be used. The maximum flow rate is, for example, set to Qv2c for a measurement less than or equal to the low threshold T1. The maximum flow rate is for example set to Qv2a for a measurement greater than or equal to the high threshold T2. Between these thresholds T2 and T1, a maximum flow rate Qv2b intermediate is set according to a linear function.
    [0020] Thus, the need for extraction to maintain good air quality in each room can be refined depending on the outdoor climate conditions. This additional adjustment makes it possible to adjust the flow control to further achieve energy savings. A further adjustment of the flow control is thus provided to the main setting, the main setting being a function of the indoor sensors providing information representative of the air quality in each room. Advantageously, the occupation of each room is taken into account at the same time as the evolution of the external climatic conditions. The extraction rates in all the extraction ducts are added to provide an overall extraction rate.
    [0021] The quality of the air is advantageously always taken into account. For example, if a dwelling is occupied by one person during the day and by several people in the evening while the evening temperature is falling in relation to the temperature during the day, the measurement of the air quality can still lead to an increase in the overall extraction rate. Figure 5 shows a top view of a box for a controlled mechanical ventilation device. The casing 3 comprises a discharge channel 50 forming in part the discharge duct 2 as described above. The box 3 comprises a plurality of extraction channels 51a, 51b, 51c, 51d and 51e each constituting in part one of the extraction ducts, as described above. The box 14 has four sides in plan view. Two extraction channels 51a and 51b are disposed on one side opposite two extraction channels 51d and 51e disposed on another side. The exhaust channel is disposed alone on one side opposite the extraction channel 51c disposed alone on the opposite side. The extraction channels are made in different diameters. The extraction channel disposed alone on its side has the largest diameter corresponding to the largest air extraction capacity. The casing 10 is thus substantially symmetrical with respect to a plane intersecting the widest extraction channel 51c and the evacuation channel 50 according to their height, passing through their central axis. The other extraction channels 51a, 51b, 51d and 51e have the same diameter. The number of channels is of course not limiting. The extraction channels 51a, 51b, 51c, 51d and 51e are bent to tangentially face the discharge channel 50. The extraction channels 51a, 51b, 51c, 51d and 51e terminate in extraction orifices. 56a, 56b, 56c, 56d and 56e disposed side by side and facing the discharge channel 50. The section of the extraction channels is reduced towards the extraction ports 56a, 56b, 56c, 56d and 56e. The box comprises access passages 53a, 53b, 53c, 53d and 53e each closed by a sealed door. These access passages 53a, 53b, 53c, 53d and 53e are each disposed opposite one of the extraction channels. The access passages are here arranged on the same face. These access passages allow the insertion of a fan in each extraction channel. It is also possible to provide a blanking plate across one or more unused extraction channels. Each extraction channel includes a location 52a, 52b, 52c, 52d and 52e for the implantation of a fan across the extraction channel. Each of these locations 52a, 52b, 52c, 52d and 52e is thus accessed through the access passage 53a, 53b, 53c, 53d and 53e associated and sealed by a hatch.
    [0022] The box also includes apertures 54a, 54b, 54c, 54d and 54e for the insertion of air analysis sensors into each extraction channel. Figure 6 is a sectional view of a portion of a channel where an air analysis sensor is installed. The sensor 8 is disposed projecting inside the extraction channel. The sensor passes through the opening 54 made in the channel. An inner wall 55 for deflecting the air partially covers the opening and comes into contact with the sensor 8. Each channel is for example equipped with such an opening for a sensor. Several openings of this type can also be installed in the same channel to install several sensors. Figure 7 is a perspective view showing the discharge channel 50. The extraction ports 56a, 56b, 56c, 56d and 56e are inscribed within the discharge channel and are arranged adjacent to each other. others. The inner walls extending the full height of the discharge channel 50 provide separation between the extraction ports 56a, 56b, 56c, 56d and 56e. As shown in section in FIG. 8, each per internal wall 57, 58a, 58b, 59a, 59b, 60a, 60b and 61 of separation with one or two adjacent channels is inclined towards the inside of the extraction channel delimited by this wall.
    [0023] A determined angle of inclination is made with respect to the central axis 62, 63, 64, 65 and 66 of each extraction channel. This inclination angle is for example between 10 degrees and 15 degrees. This angle is for example chosen greater than or equal to 12 degrees. Advantageously, the angle can be adjusted to produce a laminar air flow in the exhaust duct. Thus, in the right portion at the outlet of the exhaust duct, the air velocities are substantially conserved with respect to the air velocities at the outlet of the extraction ducts. Advantageously, the box is functional for all air extraction speeds. For example, a large extraction in the widest extraction channel 51c does not interfere with the extraction in the other extraction channels. Deviations between the air extraction speeds are thus tolerated. It should be obvious to those skilled in the art that the present invention allows other embodiments. Therefore, the present embodiments should be considered as illustrating the invention.
