Definitions
- the present invention generally relates to a method for controlling a variable recycling ventilation system and a ventilation device controlled by this control method mounted in a motor vehicle.
- motor vehicles carry ventilation systems capable of guiding outside air into the interior of a motor vehicle interior for the comfort of the passengers and recycling air from the passenger compartment by returning it. from the cockpit to the cockpit.
- these systems generally include a particulate filter through which the outside air passes before entering the cabin and a valve-like member or the like that can choose whether the air admitted in the cockpit comes exclusively from the outside (EXT mode), exclusively recycled air (Recycling Early mode) or both sources (Recycl Part mode) that optimizes the air in the cabin.
- the total recycling position is not a position of comfort for the established regime because it does not renew the air of the passenger compartment which is inconvenient for the occupants after only a few minutes (about 10 minutes).
- return to an outside air position is a source of acoustic nuisance for passengers, it does not allow air circulation to the rear passengers, it can cause additional cabin pollution compared to carbon dioxide, for example, and it generates fogging of the vehicle especially in cold climate when the air conditioning is not running OFF (air conditioning compressor OFF).
- the efficiency of the filter is of the order of 50% (plus or minus 15%).
- the document FR 2958219 describes a partial recirculation ventilation system comprising a pollution sensor in which the recirculation is controlled according to the level of pollution.
- this system does not solve the problem related to fogging or the need for fresh air total recirculation mode to use when pollution is very important
- An object of the present invention is to address the disadvantages of the documents of the prior art mentioned above and in particular, all First, to propose a method and a ventilation system ensuring a good air quality in a vehicle interior while preventing the appearance of fogging and allowing a renewal of the air.
- a first aspect of the invention relates to a method for controlling a ventilation system, the ventilation system comprising a means for distributing air to a vehicle interior and arranged to modify a recycled airflow ratio. on a total air flow rate distributed in the passenger compartment, the method being arranged to control the distribution means according to a first partial recycling mode having a first ratio of air flow recycled to the total air flow, and a second partial recycling mode having a second ratio of air flow rate recycled to the total air flow rate different from the first gear, characterized in that the first and second partial recycling modes are automatically implemented alternately.
- a first partial recycling mode having a first ratio of air flow recycled to the total air flow
- a second partial recycling mode having a second ratio of air flow rate recycled to the total air flow rate different from the first gear
- the first partial recycling ratio is greater than the second partial recycling ratio and in that the first partial recycling mode is implemented longer than the second partial recycling mode.
- the first partial recycling mode is implemented longer than the second partial recycling mode.
- the first ratio is between 70% and 90% In this way, it effectively limits the entry of pollution into the passenger compartment.
- the second ratio is between 40% and 60%.
- the first mode is implemented at least 83% of the time.
- the sequence of partial recycling modes makes it possible to have renewed and pollution-free air in the passenger compartment.
- the control method is implemented when a predetermined threshold of pollution is detected. Thus, one can breathe well and drive even in extreme pollution conditions.
- a particularly interesting embodiment is that when the first partial recycling mode is controlled, an air conditioner compressor is turned on. In this way, fogging is prevented.
- a second aspect of the invention is a ventilation system of a motor vehicle comprising a filter arranged to filter an air intended for a passenger compartment of the vehicle, a pollution sensor arranged to detect a concentration of pollutant particles in an outside air, a first supply duct arranged to supply outside air to the passenger compartment, a second supply duct arranged to supply recycled air from the passenger compartment to the passenger compartment, a distribution means arranged to receive the air admitted by the first and second supply ducts and regulate air flow rates admitted by the first and second supply ducts according to the pollution sensor data, characterized in that the filter is located downstream of the means of distribution
- a particularly interesting embodiment consists in that the ventilation system comprises a control unit arranged to control the distribution means according to the control method of the first aspect of the invention. In this way, the system allows good air quality in the passenger compartment without fogging.
- a third aspect of the invention is a motor vehicle comprising at least one ventilation system according to the second aspect of the invention.
- FIG. 1 shows a general structural diagram of a ventilation system according to a preferred embodiment of the invention
- FIG. 2 shows a graph illustrating the operating modes of the system and their sequence implemented according to the method of the present invention.
- FIG. 2 represents a control method of a ventilation system implemented preferably when a predetermined threshold of pollution is detected.
- This piloting method controls a ventilation system that includes a means for distributing air to a vehicle interior and is arranged to modify a ratio of air flow recycled to the total air flow distributed in the passenger compartment,
- the method is arranged to control a ventilation system 1 according to a first partial recycling mode in which the intake air has a first recycled air flow rate ratio on the total air flow, by example the first ratio is between 70% and 90%, it is preferably 80%. However, depending on the climatic conditions or the start of the air conditioner compressor, the first ratio may be greater than 95%. Therefore, when the first partial recycling mode is controlled, an air conditioner compressor is preferably turned on to avoid fogging.
- the ventilation system 1 can drive the ventilation system 1 according to a second partial recycling mode in which the intake air has a second ratio of recycled air flow rate to the total air flow rate different from the first ratio, from preferably lower than this, for example between 40 and 60, preferably 50%.
- the method activates the first and second partial recycling modes alternately one after the other so as to alternate the air renewal phases by activating the second mode for 2 minutes for example and the recycling phase by activating the first fashion during 10 minutes, for example, so that the first mode is activated most of the time, preferably at least 83% of the time.
- the invention also relates to the ventilation system 1 of a motor vehicle as illustrated in FIG.
- This system comprises a filter 5 arranged to filter an air intended for a passenger compartment of the vehicle, a pollution sensor (not shown) arranged to detect a concentration of pollutant particles in an outside air, a first supply duct 2 arranged to supply power to the vehicle. outside air to the passenger compartment, a second supply duct 3 arranged to supply recycled air from the passenger compartment to the passenger compartment, a distribution means 4 arranged to receive the air admitted by the first and second supply ducts and regulate air flow rates admitted by the first and second supply ducts according to the pollution sensor data, characterized in that the filter 5 is located downstream of the distribution means 4.
- the ventilation system 1 comprises a control unit arranged to control the dispensing means 4 according to the method described above.
- the invention also relates to a vehicle comprising a ventilation system described above.
