    [0001] FIELD OF THE INVENTION The invention relates to air analysis devices which are intended to equip heating / air-conditioning installations equipped with air-conditioning systems. filter (s) and intended to supply treated air to an enclosure. Furthermore, this invention relates to any system comprising at least one enclosure to be supplied with air treated by a heating / air conditioning system with filter (s) and supply flap to control its air supply from the outside and / or air from the inside of the enclosure (or recirculated air). Therefore, it concerns at least vehicles, possibly of automobile type, and buildings.
    [0002] The term "filter" is used herein to mean equipment charged with filtering into the air which supplies it with at least one chemical species in solid form (for example fine particles or dust) or in gaseous form (for example CO 3 , SO2, NO2, 02 or CO2), and / or dehumidify the air that feeds it.
    [0003] Some heating / air conditioning systems, and in particular those that equip vehicles, possibly cars, include an air analysis device responsible for controlling the quality of the air to feed at least one enclosure (such as a passenger compartment). This device generally comprises a single sensor responsible for carrying out measurements representative of the concentration of at least one chemical species (generally a gaseous or solid pollutant (particles)) in the air supplying the installation that it equips. . When the sensor detects that the concentration of a chemical species is greater than a threshold, it warns its device so that it triggers the implementation of a suitable strategy of supplying the installation and / or decontamination of the plant. 'pregnant. This strategy depends on the location of the sensor and therefore the air it can analyze.
    [0004] 3031574 2 For example, when the sensor is located upstream of the supply flap and responsible for analyzing the outside air, the crossing of a detection threshold triggers a ban on supplying the enclosure with outside air ( and therefore only recirculated air (that is to say from the enclosure) 5 feeds the installation), except for very short periods of time to regenerate the oxygen indoor air. When the sensor is installed downstream of the supply flap, it can analyze the outside air and the recirculated air, and thus makes it possible to know both the level of pollution outside the enclosure and the level of pollution. in the enclosure in some modes of operation of the installation. We can then implement strategies a little more complex than the one presented in the previous paragraph. However, these strategies are still too limited, particularly since it is not possible to know the level of pollution of the outside air when the installation is supplied with recirculated air, nor the level of pollution of the recirculated air when the installation is supplied with outside air. Moreover, the aforementioned two locations of the sensor do not make it possible to precisely determine the efficiency of the filtering, for example to inform the persons who are present in the enclosure and / or to request a replacement of the filter when this efficiency becomes lower than a threshold. The invention is therefore particularly intended to improve the situation. It proposes for this purpose an air analysis device, on the one hand, intended to equip a heating / air conditioning system comprising at least one filter, capable of filtering at least one chemical species contained in an air of supply from the outside and / or inside of an enclosure and / or dehumidify this supply air, and adapted to supply treated air to the enclosure, and, secondly, comprising at least one sensor able to make measurements representative of the concentration of this chemical species and / or hygrometry in the air that feeds it. This device is characterized by the fact that it also comprises: a part comprising at least three inputs intended to be placed upstream of the sensor and to be supplied respectively with air coming from outside, with air coming from the inside the chamber and filtered air from an area of the installation which is located downstream of the filter, and - control means adapted to selectively control the passage of air 5 through one of the inputs according to a received instruction so that the sensor analyzes this air. Thus, it may now be possible to know the level of pollution of the outside air, the level of pollution of the recirculated air and the efficiency of the filtering of the outside air and / or the recirculated air, that the installation is the supply of outside air or recirculated air. The air-analysis device according to the invention may comprise other characteristics that can be taken separately or in combination, and in particular: its control means may comprise, on the one hand, a rotating disk placed against the and having an opening adapted to allow the passage of air through one of these inputs when it is placed opposite it, and, secondly, a clean electric motor to drive in rotation the rotating disk for placing its opening next to an input corresponding to the received instruction; It may also comprise a duct secured to its part and having an internal part in which is housed at least a portion of the sensor and an output adapted to be coupled to the installation upstream of the filter; it may also include an electric air pump to suck the air to pass through the selected inlet. The invention also proposes a heating / air-conditioning system capable of supplying treated air to an enclosure and comprising at least one filter capable of filtering at least one chemical species contained in an air supply coming from outside and / or from the interior of the enclosure and / or dehumidify this supply air, and an air analysis device of the type shown above. The heating / air-conditioning system according to the invention can comprise other characteristics that can be taken separately or in combination, and in particular: the room and means of control of its air-analysis device can be installed in upstream of the filter and downstream of a supply flap which is arranged to control its supply of air from outside and / or air from inside the enclosure; it may comprise, firstly, a supply duct supplied with air by the supply flap and comprising an outlet secured to the room for supplying at least one of its outside air outlets and / or in air from the enclosure, a second part, an opening communicating with an area located downstream of the filter, and, thirdly, a connecting conduit providing a connection between this opening and another of the inputs of the room ; alternatively, it may comprise, firstly, an opening 15 communicating with a first zone located upstream of the filter, a second portion, another opening communicating with an area located downstream of the filter, a third part, a connecting conduit providing a connection between this opening and one of the inputs of the part, and, fourthly, another connecting conduit providing a connection between this other opening and another of the inputs of the room ; it may also comprise, on the one hand, yet another opening communicating with a second zone situated upstream of the filter, and, on the other hand, yet another connecting conduit providing a connection between this latter opening and yet another entries from the room. The invention also proposes a vehicle, possibly of automobile type, and comprising at least one enclosure and a heating / air-conditioning installation of the type presented above. Other features and advantages of the invention will be apparent from the following detailed description and the accompanying drawings, in which: FIG. 1 schematically and functionally illustrates an example of an installed heating / air-conditioning system in a vehicle and equipped with an exemplary embodiment of an air analysis device according to the invention, - Figure 2 schematically illustrates, in a perspective view, the air analysis device of FIG. 1, and FIG. 3 schematically illustrates, in a sectional view in a transverse plane, a part of the air analysis device of FIG. 2. The object of the invention is in particular to propose a device for DA air analysis intended to equip a heating / air-conditioning system IC filter (s) FA, itself intended to equip a system S comprising at least one enclosure H. In what follows, it is considered, as of non-limiting example, that the Heating / air-conditioning system IC is part of a system S arranged in the form of a motor vehicle, such as a car. The enclosure H of the vehicle S is therefore its cabin. But the invention is not limited to this type of system. It concerns in fact any type of land vehicle, maritime (or fluvial), or air, and any type of building, since it comprises at least one enclosure intended to be supplied with air treated by a heating / air-conditioning system. filter (s). FIG. 1 shows schematically and functionally an example of an IC heating / air-conditioning installation installed in a vehicle (or system) S and coupled to an exemplary embodiment of a DA air analysis device according to FIG. 'invention. Here, the heating / air conditioning system IC is located in the CO engine compartment of the vehicle (or system) S and intended to supply the passenger compartment H with treated air.
    [0005] As illustrated, this installation (heating / air conditioning) IC comprises in particular a blower (or motor-fan unit (or GMV)) PU, at least one FA filter, a cold loop (or air conditioning loop) BF, a hot loop (or heating loop) BC, a VA power shutter, a VM mixing flap and Vj distribution flaps.
    [0006] The blower PU is supplied with air coming from outside the passenger compartment H and / or with air coming from the interior of the passenger compartment H (or recirculated (or recycled) air) by the supply flap (or air inlet) VA. The outside air is derived from a first duct C1, and the recirculated air comes from the passenger compartment H via a second duct C2. The air flow rate supplied by the PU blower depends on the power level which has been automatically calculated by a computer CS which manages the installation IC, or else chosen (and possibly programmed) by a passenger of the vehicle S by means of a control member which is installed in the cockpit H, generally in the dashboard. The position of the VA supply flap, and therefore the proportions of outside air and recirculated air that feed the installation IC (and here its PU blower), is / are controlled (s) by the computer CS. The FA filter is responsible for filtering into the air which feeds at least one chemical species in solid form (such as for example fine particles or dust) or in gaseous form (such as for example CO, O 3, SO 2, NO 2 , 02 or CO2), and / or dehumidify the air that feeds it. In the example shown non-limitatively in FIG. 1, the filter FA is installed downstream of the PU pulser and upstream of the cold loop BF. But it could be implanted in other places after the CA sensor of the DA analysis device. In addition, it should be noted that the installation IC could comprise several filters FA (at least two). The cold loop BF is supplied with air by the PU blower. It comprises in particular an evaporator EV (traversed by the air which is derived from the PU blower), as well as a compressor, a condenser and a circuit in which a refrigerant circulates and which is coupled to the evaporator EV, to the compressor and the condenser. The output of the evaporator EV is coupled to a conduit which supplies here, on the one hand, a mixing chamber CM having a first input 25 whose access is controlled by the mixing flap VM, and on the other hand , the hot loop BC whose access is controlled by the VM mixing flap and the output feeds a second input of the mixing chamber CM. The hot loop BC is intended to heat the air which is derived (here) from the evaporator EV and which is intended for the passenger compartment H of the vehicle S, possibly after mixing with the less hot air present in the vehicle. mixing chamber CM. It comprises heating means MC comprising, for example, a heater, such as for example a heat exchanger (in which circulates a liquid which is optionally heated by electric heating resistors (for example of high voltage CTP type), or by a heat-combustion heater), and / or an electric radiator, for example consisting of electric heating resistors (for example of high voltage CTP type).
    [0007] These heating means MC are charged, when they operate, to heat the air passing through them and which is (here) coming from the evaporator EV, in order to deliver heated air to their outlet which feeds the second entrance to the CM mixing room. The mixing chamber CM is connected to ducts which are here intended to supply dispensing openings placed in the passenger compartment H of the vehicle S and dedicated to the deicing S1, to the central ventilation S2, to the front legs S3 and at the rear feet S4. Access to these conduits is controlled by the distribution flaps Vj (here two in number (j = 1 or 2), but there could be more, for example three or four). Note that the distribution flap V2 here controls access to a duct that feeds the front foot valves S3 and rear feet S4. But we could provide two distribution flaps to control access respectively to the front foot vents S3 and S4 rear foot vents. It will also be noted that these different distribution flaps Vj are generally coupled together by a kinematics which is for example moved by one or two micromotors. The respective positions of the distribution flaps Vj depend on the distribution outlets at which a passenger of the vehicle S wishes that the treated air from the IC installation is delivered. These dispensing outlets may be chosen by the passenger by means of at least one control member installed in the cockpit H, generally in the dashboard. The mixing flap VM is intended to control the distribution of air, which is provided by the VA supply flap (and which has here passed through the evaporator EV), between the mixing chamber CM and the heating means MC . It thus makes it possible to mix (or mix) in a controlled manner a part of the air which has passed through the cold loop BF (possibly in operation) and the air which has passed through the hot loop BC. Its position depends on the operating mode of the IC installation.
    [0008] The mode of operation of the installation IC is chosen by a user of the vehicle S or by the computer CS, possibly as a function of choice made by a user of the vehicle S. In all cases, the implementation of the selected operating mode is controlled by the computer CS 5 and involves an operation of at least one of the elements that are the PU blower, the cold loop BF, the hot loop BC, the supply flap VA, the flap of VM mixing and distribution flaps Vj. As illustrated in FIGS. 1 and 2, the air analysis device DA comprises at least one AC sensor, one piece PA and control means MC. The part PA comprises, as illustrated in FIG. 2, at least three inputs Ej intended to be placed upstream of the sensor CA and to be supplied respectively with air coming from the outside, with air coming from the interior of the passenger compartment. H (or recirculated air), and filtered air from an area of the IC installation which is located downstream of the FA filter. For example, a first input El (j = 1) may be supplied with outside air, a second input E2 (j = 2) may be supplied with recirculated air, and a third input E3 (j = 3) may be supplied with air. filtered. It will be noted that in the embodiment illustrated in FIG. 2, the piece PA is installed downstream of the supply flap VA and secured to the outlet of a duct of the installation IC which is supplied with outside air and / or in recirculated air by this VA supply flap. Consequently, the first E1 and second E2 inputs receive both the outside air and the recirculated air directly. Therefore, in an alternative embodiment the first and second E2 inputs could be merged to form a single common input. In this variant, the supply of the room PA with outside air or recirculated air depends on the placement of the supply flap VA in a position which only allows the passage of the outside air or in a position which allows only the passage of recirculated air.
    [0009] Furthermore, in the embodiment illustrated in FIGS. 1 and 2, the third input E3 is coupled to the output of a connecting duct CL whose input is coupled to an opening defined in a duct of the installation IC. which couples the filter FA to the cold loop BF. This allows the analysis of the filtered air.
    [0010] The embodiment illustrated in FIG. 2 is in fact intended to allow both a complete integration of the device DA in the installation IC and an offset of the device DA in the immediate vicinity of the installation IC and a coupling between this device. DA device and IC installation via at least three link conduits. Indeed, in the latter case, at least each input Ej of the device DA must be coupled to the installation IC via a connecting pipe to be supplied with air to be sampled, and the output of the device DA may be coupled to the IC installation via another connecting conduit, or communicate with the engine compartment CO to evacuate outside the air analyzed. Specifically, the IC installation must include at least three openings for the collection of a portion of the outside air that feeds it, recirculated air that feeds it and air that it has filtered through. by means of its FA filter. For example, a first opening may be defined in the first conduit C1 and be coupled to the input of a first connecting conduit 15 whose output is coupled to the first input E1 of the component PA, a second opening may be defined in the second conduit C2 and being coupled to the input of a second connecting conduit whose output is coupled to the second input E2 of the workpiece PA, and a third opening can be defined in a conduit coupling the filter FA to the BF cold loop and be coupled to the input of a third connecting conduit whose output is coupled to the third input E3 of the piece PA. It will also be noted that in the embodiment illustrated in FIG. 1 and in which the device DA of FIG. 2 is integrated in the installation IC, the air analyzed by the sensor CA continues its course in the installation IC but can not be evacuated to the outside of the latter (IC). It will also be noted that in the embodiment illustrated in FIG. 2, the part PA comprises a fourth input E4 which can be powered (via a connection duct) by air taken from a selected zone 30 of the vehicle S or another selected area of the IC facility. The sensor CA is arranged to perform measurements which are representative of the concentration in the air which feeds it (and more precisely that which sweeps it and which comes from an input Ej) of the chemical species 3031574 (or of each chemical species) which is filtered by the FA filter and / or hygrometry in the air that feeds it (and more precisely who sweeps it and which comes from an input Ej). For example, this AC sensor may comprise at least one resistive element in MOX technology ("metal oxide semiconductor") and having a resistance varying as a function of the concentration of a single odorless gas, such as, for example, carbon dioxide. nitrogen (or NO2) or carbon monoxide (or CO), or odorous, such as a carbon gas type CxHy. Alternatively, or in addition, this AC sensor may be arranged to determine the concentration of particles having diameters greater than a threshold or within a predefined range. In general, the AC sensor may, for example, be suitable for measuring the concentration of at least one chemical species chosen from at least CO, O 3, SO 2, NO 2, O 2, CO 2, PM 10 and PM 2.5 ( even PM1), and / or hygrometry in the air that sweeps it.
    [0011] It will be noted that in the example shown in non-limiting manner in FIGS. 1 and 2, the device (of air analysis) DA comprises only one AC sensor. But it could include several (at least two). It will also be noted that in the embodiment illustrated in FIGS. 1 and 2, the device DA comprises a conduit CD having an inlet 20 secured to the part PA (downstream of its inputs Ej) and having an internal part in which the air to be analyzed and is housed at least a portion of the AC sensor. This CD conduit also includes an output that is adapted to be coupled to the IC installation upstream of the FA filter. This coupling can be done either directly by securing to an inlet of a conduit of the installation IC or equipment of the latter (IC), such as for example its PU pulser, or indirectly via a connecting conduit. In an alternative embodiment already mentioned, the output of the conduit CD could communicate with the engine compartment CO to evacuate outside air analyzed. In the remote variant, it is conceivable to add to the device DA, downstream of the sensor CA, a filter intended to absorb the different species analyzed in order to allow a "reset" of the atmosphere prevailing in the conduit CD where the analysis is carried out so as not to distort the following analyzes.
    [0012] In a variant embodiment not illustrated, the sensor CA could be attached to a conduit of the installation IC having an inlet secured to the part PA (downstream of its inputs Ej) and having an internal part in which the air circulates. power supply (outside and / or recirculated).
    [0013] The control means MC are adapted to selectively control the passage of air through one of the inputs Ej according to a received instruction so that the sensor AC analyzes this air. The instruction may, for example, be issued from the computer CS. But it can come from another calculator of the vehicle S, for example the one which is responsible for providing information at least to the driver of the vehicle S via the on-board man / machine interface. It will be understood that, thanks to the invention, it is now possible to determine, when desired, and during short analysis phases (programmed or required), the level of pollution of the outside air, the pollution level of the recirculated air and the efficiency of the filtering of the outside air and / or the recirculated air, whether the installation is supplied with outside air or recirculated air. According to the embodiment envisaged for the device DA (all integrated or remote), the phases of analysis of the air may possibly require the placement of the supply flap VA in positions 20 appropriate to each of them. It should be noted that the efficiency of the filtering of the outside air and / or the recirculated air can be determined by making a comparison between the result of an analysis of the supply air (outside and / or recirculated) before the filtering by the filter FA and the result of an analysis of the air filtered by the filter FA.
    [0014] The results of the measurements carried out by the sensor CA are transmitted to a computer of the vehicle S which is responsible for providing passengers of the latter (S) with information relating to its operation, to the aerothermal energy in its passenger compartment H and to its environment. outside. This calculator is then responsible for informing the passengers of the vehicle S at least the pollution level outside the passenger compartment H, the level of pollution in the passenger compartment H, and the efficiency of the filtering of the vehicle. outside air and / or recirculated air. It can also deduce from the results received the level of saturation or clogging of at least a portion of the filter FA, and request a replacement of at least a portion of the filter FA when this level becomes greater than a threshold. Note that the computer could trigger the transmission of pollution information (at least outside the vehicle S), by wave (possibly via the Internet) to neighboring or distant vehicles. The control means MC can be made in different ways. One of these ways is illustrated without limitation in FIGS. 1 to 3. In the example illustrated, the control means MC comprise a rotary disk DR and an electric motor ME. The rotary disc DR is placed against the inputs Ej of the part PA and has an opening OV which is adapted to allow the passage of air through one of the inputs Ej when it is placed opposite it. The electric motor ME is adapted to rotate the rotary disk DR to place its opening OV 15 opposite an input Ej which corresponds to the received instruction. This electric motor ME may, as shown without limitation, be secured to the wall of the conduit CD which is secured to the AC sensor and which is coupled to the rotary disk DR and the workpiece PA. For example, if the received instruction is associated with the outside air analysis, the electric motor ME rotates the rotating disk DR to place its opening OV opposite the first input E1, which obstructs all other inputs E2 to E4. The outside air from the first duct C1 can then pass through the first entry El and the opening OV (arrow F1), then enter the duct CD to scan the sensor CA 25 (arrow F2) to be analyzed by the latter. (IT). Likewise, if the instruction received is associated with the analysis of the indoor air, the electric motor ME rotates the rotary disc DR to place its opening OV opposite the second input E2, which obstructs all the others. inputs E1, E3 and E4. The interior air from the second conduit C2 can then pass through the only second inlet E2 and the opening OV, and then enter the conduit CD to scan the sensor CA to be analyzed by the latter (CA). Also likewise, if the instruction received is associated with the analysis of the filtered air, the electric motor ME rotates the rotary disk DR to place its opening OV opposite the third input E3, which obstructs all other inputs E1, E2 and E4. The filtered air can then pass through only the third inlet E3 and the OV opening, and then enter the conduit CD to scan the AC sensor for analysis by the latter (CA).
    [0015] The rotational drive of the rotary disc DR can be done via a wheel or a coupling gear RC rotated by the electric motor ME. If a coupling wheel is used, its peripheral edge and the peripheral edge of the rotary disc DR are preferably coated with a material facilitating the drive without slipping. If a coupling pinion is used, the peripheral edge of the rotary disk DR must include teeth intended to mesh with its own teeth. It will be noted that when the device DA is integrated in the installation IC, the depression existing upstream of the blower enables automatic sampling of the air to be analyzed and therefore the crossing of the inlet E j selected by this air to be analyzed. On the other hand, when the device DA is deported (and therefore when all its inputs Ej are coupled to the installation IC via connecting conduits), it must also include an electric air pump intended to suck in the air to pass through. Ej input selected. This electric air pump may, for example, be a small turbine installed downstream of the AC sensor and whose power supply is controlled by the control means MC, possibly according to instructions from the computer supervising the installation IC or another embedded calculator. Other embodiments of the control means MC may be envisaged. Thus, the control means MC could comprise solenoid valves (hydraulic or pneumatic or mechanical) or flaps associated respectively with the different inputs Ej, replacing the rotary disk DR. Moreover, each entry Ej could be associated with his / her own sensor (s). The invention offers several advantages, among which: an improvement of the control strategy of the heating / air-conditioning installation and any means of decontamination of the enclosure, a monitoring of the pollution levels in the enclosure and outside the 3031574 14 the enclosure and the effectiveness of filtering, - making available to those present in the enclosure of many information relating to pollution in the enclosure, pollution outside of the enclosure, and the effectiveness of filtering. 5
