[0003] In existing technologies, vehicle air conditioning systems typically install activated carbon or adsorbent filters at the air intake of the air conditioning assembly. These filters mainly capture or temporarily store some gaseous pollutants and odors in the air through physical adsorption, thereby performing preliminary purification of the air flowing through the air intake of the air conditioning assembly.

[0004] However, the above solutions cannot effectively purify the odors and pollutants generated by the internal structure of the air conditioning system itself. Summary of the Invention

[0027] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] It should be noted that odors inside passenger vehicles mainly come from two sources: one is the odor of new cars, which is mainly caused by volatile organic compounds released from interior materials; the other is the odor of old cars, especially the odor accumulated in the air conditioning housing, evaporator, and air ducts.

[0030] The air processed by the evaporator may carry musty, earthy, or sour odors. The evaporator surface, due to its long-term high humidity and grease buildup, is highly susceptible to microbial growth, carrying odor molecules and gaseous pollutants produced by microbial metabolism. These are then blown into the passenger compartment, posing a potential threat to passenger health. Furthermore, the air conditioning casing and duct interior may accumulate strong, persistent odors, such as body odor, the fishy smell after fishing, or the scent of cheap perfumes or air fresheners, all of which can negatively impact passenger comfort.

[0031] In the existing technology, in order to solve the above problems, activated carbon / adsorbent filter elements are usually installed at the air inlet of the air conditioning assembly. However, they can only capture or temporarily store pollutants. Moreover, because they are located at the front end of the air conditioning system, they cannot effectively capture VOCs (Volatile Organic Compounds) and mold odors generated in the evaporator, air conditioning casing and downstream air duct, thus affecting the purification function of the air conditioning system.

[0032] Meanwhile, due to its non-uniform pore structure, activated carbon adsorbs both nano-sized and micron-sized particles, resulting in limited adsorption capacity for odor molecules and easy saturation, requiring frequent replacement. Therefore, relying solely on adsorption materials is insufficient to achieve long-term and stable purification effects. Some vehicle models also use photocatalytic technology to decompose gaseous pollutants. As a catalyst, photocatalysts can decompose harmful gases such as formaldehyde into water and carbon dioxide, theoretically offering advantages such as no adsorption saturation and long lifespan. However, existing photocatalytic purification devices are mostly independent air purifiers, requiring a forced air supply from an air pump to increase gas-solid contact efficiency, which not only increases energy consumption but also occupies space.

[0033] In summary, existing technologies suffer from at least the following key drawbacks: activated carbon filters have limited adsorption capacity and are prone to saturation; photocatalytic devices consume a lot of energy and occupy a large space; and some solutions present a conflict between purification efficiency and airflow. These problems urgently need to be addressed through optimizing the purification structure design, improving catalytic efficiency, and reducing energy consumption to achieve the goal of efficient, low-resistance, and long-life in-vehicle air purification.

[0034] Based on this, combined Figures 1-9 As shown, this application proposes an improved air conditioning system 1000, which improves purification efficiency and reduces energy consumption through innovative structural design and process optimization, thus establishing the last air quality management barrier of the air conditioning system 1000.

[0035] The air conditioning system 1000 of the present invention is described below with reference to the accompanying drawings.

[0036] like Figure 1 and Figure 2 As shown, an air conditioning system 1000 according to an embodiment of the present invention includes: an air conditioning assembly 100 and a purification module 200.

[0037] Among them, such as Figure 1 and Figure 2 As shown, the air conditioning assembly 100 includes an evaporator 110. The evaporator 110 is used to achieve cooling and dehumidification functions to ensure the operating performance of the air conditioning system 1000.

[0038] In a specific example, the high-temperature, low-pressure liquid refrigerant expands and evaporates in the pipes of the evaporator 110, absorbing a large amount of heat, which cools the air flowing through the fins of the evaporator 110, and the condensed water vapor condenses on the surface of the fins to achieve dehumidification.

[0039] It should be noted that, in order to prevent water droplets from adhering to the evaporator 110 and increasing the resistance and noise of the evaporator 110, and in order to improve the heat exchange efficiency of the evaporator 110, the surface of the evaporator 110 is usually treated with hydrophilic treatment and coated with a hydrophilic coating. However, the hydrophilic coating may produce a slight acidic smell, and when the cooling is insufficient, the surface of the evaporator 110 is prone to adsorbing environmental odors, forming unpleasant odors such as "foot odor". Such odors and mold cannot be completely removed by traditional filter elements and need to be decomposed by subsequent catalytic devices.

[0040] Based on this, such as Figure 1 and Figure 2As shown, the purification module 200 is located downstream of the evaporator 110. The purification module 200 is used to remove gaseous pollutants from the air. It should be noted that downstream refers to the rear of the airflow direction. Therefore, the arrangement of the purification module 200 downstream of the evaporator 110 can be understood as follows: the air in the air conditioning system 1000 first passes through the evaporator 110 and then flows through the purification module 200. In this way, the purification module 200 can directly catalytically decompose the acidic smell, musty smell, bacteria, and VOCs generated by the evaporator 110 and the air conditioning assembly 100 during operation, completely eliminating the technical problem that the pre-activated carbon or antibacterial filter cannot capture the source of odors at the downstream end.

[0041] In other words, compared with the traditional activated carbon / adsorbent filter element that is only installed at the air inlet of the air conditioning assembly 100, this application arranges the purification module 200 downstream of the evaporator 110 to realize the post-purification module 200, thereby eliminating the capture blind zone and significantly improving the deodorization efficiency of the air conditioning system 1000.

[0042] Understandably, compared to existing technologies, the air conditioning system 1000 of this application places the purification module 200 downstream of the evaporator 110 to directly catalytically decompose the acidic smell, musty smell, bacteria and VOCs generated by the evaporator 110 and the air conditioning assembly 100 during operation, thus completely eliminating the technical problem that the pre-activated carbon or antibacterial filter cannot capture the odor at the back end of the air conditioning system 1000.

[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, the air conditioning assembly 100 includes a housing 130, and a main air duct 131 is formed inside the housing 130. The main air duct 131 has a first air outlet 1311. The purification module 200 is arranged close to the first air outlet 1311, which not only allows the purification module 200 to be arranged downstream of the evaporator 110, but also allows the purification module 200 to be arranged close to the outlet of the air conditioning assembly 100. This allows the purification module 200 to effectively catalytically decompose the acidic smell, musty smell, bacteria and VOCs generated by the evaporator 110 and the air conditioning assembly 100 during operation.

[0044] In some embodiments, such as Figure 1 and Figure 2As shown, the air conditioning assembly 100 includes at least one damper 120 and a heater 140. The damper 120 is arranged downstream of the evaporator 110, and the heater 140 is arranged downstream of the damper 120. The damper 120 is used to regulate the temperature and / or direction of the airflow, and the heater 140 is used to heat the air flowing through it. The purification module 200 is arranged downstream of either the damper 120 or the heater 140. It should be noted that when the purification module 200 is arranged downstream of the damper 120, the purification module 200 can be arranged between the damper 120 and the heater 140, or it can be arranged downstream of the heater 140.

[0045] The heater 140 mainly provides the necessary electric heating source for heating. When the heater 140 is working, the air temperature around the heater 140 increases, and the moisture is evaporated quickly. By arranging the purification module 200 downstream of the heater 140, the heater 140 can be used to quickly evaporate the moisture around the purification module 200, which not only protects the purification module 200 from water corrosion, but also uses the residual heat of the heater 140 to increase the catalytic reaction rate, thereby extending the service life of the purification module 200 and improving its working performance.

[0046] Meanwhile, by arranging the purification module 200 downstream of the damper 120, that is, by placing the damper 120 between the evaporator 110 and the purification module 200, the damper 120 can be used to block condensate from directly entering the purification module 200, ensuring safety and reliability.

[0047] In some embodiments, the heater 140 is a PTC heater, which is used to heat the air flowing through the air conditioning system 1000 when the air conditioning system 1000 is operating in heating mode, so as to ensure the heating effect of the air conditioning system 1000.

[0048] In some embodiments, combined with Figure 1 and Figure 2 As shown, the air conditioning assembly 100 includes two dampers 120, one of which is a ventilation damper and the other is a heating damper. In terms of airflow direction, the heating damper is positioned directly opposite the heater 140. When the air conditioning system 1000 is in cooling mode, the ventilation damper can be opened directly. When the air conditioning system 1000 is in heating mode, both the ventilation damper and the heating damper can be opened simultaneously to ensure the cooling and heating effects of the air conditioning system 1000.

[0049] In some embodiments, combined with Figure 1 and Figure 2As shown, the air conditioning assembly 100 includes a first motor 172, which drives the ventilation damper and the heating damper to rotate, so as to control the opening angle of the ventilation damper and the heating damper by means of the first motor 172, thereby realizing the ratio adjustment of the cold air from the evaporator 110 and the hot air from the heater 140, and thus obtaining the required air outlet temperature.

[0050] The first motor 172 mentioned here can be a rotary motor or a linear motor, etc.

[0051] In some embodiments, such as Figure 1 As shown, the air conditioning assembly 100 includes a housing 130, inside which a main air duct 131 is formed. The evaporator 110 and the purification module 200 are both located within the main air duct 131. This allows the purification module 200 to directly catalyze and decompose odors within the main air duct 131, thereby decomposing odors downstream of the evaporator 110. This overcomes the blind spots of the pre-filter. Furthermore, by placing the purification module 200 within the main air duct 131, air flowing through the duct can effectively pass through the purification module 200 without requiring additional energy for airflow, reducing operating costs. Simultaneously, it increases the contact area between the purification module 200 and the air, improving catalytic efficiency.

[0052] Meanwhile, by placing both the evaporator 110 and the purification module 200 within the main air duct 131, and by placing both the evaporator 110 and the purification module 200 within the housing 130, the housing 130 can be used to support and protect the evaporator 110 and the purification module 200, thereby extending their service life and improving their positional stability to ensure their performance.

[0053] Optionally, such as Figure 2 As shown, the air conditioning system 1000 also includes an air supply duct 300. A main air duct 131 is formed inside the housing 130. The evaporator 110 is located within the main air duct 131. The air inlet of the air supply duct 300 is connected to the first air outlet 1311 of the main air duct 131. The second air outlet 320 of the air supply duct 300 is used to direct the air exhausted by the air conditioning system 1000 to the target area inside the vehicle. The purification module 200 is located within the air supply duct 300. That is to say, the purification module 200 is not limited to being located within the main air duct 131, but can also be located within the air supply duct 300 downstream of the main air duct 131. In this way, the purification module 200 can also be used to decompose odors downstream of the evaporator 110, overcoming the blind spot of the pre-filter.

[0054] Meanwhile, the purification module 200 is located inside the air supply duct 300, so that the air flowing through the air supply duct 300 can effectively flow through the purification module 200 without consuming additional energy as the power to draw air through the purification module 200, reducing operating costs. At the same time, it is easy to increase the contact area between the purification module 200 and the air, thereby improving catalytic efficiency.

[0055] In addition, by setting up the air supply duct 300, the air exhausted by the air conditioning assembly 100 can be directed to the target area inside the vehicle, which is convenient for directional air supply or zoned air supply. This allows the air conditioning system 1000 to distribute air more accurately, more comfortably, and more energy-efficiently, thereby improving the functionality and user experience of the air conditioning system 1000.

[0056] It should be noted that in some hybrid vehicles, the heater 140, the indoor condenser, and the warm air core may be installed simultaneously, which limits the internal space of the air conditioning assembly 100 and makes it impossible to install more purification components. Therefore, by placing the purification module 200 in the air supply duct 300, the purification module 200 can be arranged in the air supply duct 300 without occupying extra space inside the air conditioning assembly 100, and without the need to add aerodynamic components and photothermal energy components. The air catalytic purification function is achieved with zero energy consumption, providing the last purification barrier before the air enters the passenger compartment.

[0057] In some embodiments, combined with Figure 1 and Figure 2 As shown, the second air outlet 320 includes a main air outlet 321 and a secondary air outlet 322. The main air outlet 321 is positioned directly opposite the first air outlet 1311 of the air conditioning assembly 100. There are two secondary air outlets 322, which are spaced apart on opposite sides of the first air outlet 1311. The main air outlet 321 and the two secondary air outlets 322 work together to direct the air exhausted by the air conditioning system 1000 to the target area inside the vehicle, so as to achieve uniform air supply or local air supply throughout the vehicle to meet the comfort needs of different occupants.

[0058] In some embodiments, combined with Figure 1 and Figure 2 As shown, the air conditioning system 1000 also includes two second motors 700, which correspond one-to-one with two auxiliary air outlets 322. Each auxiliary air outlet 322 is driven by a second motor 700 to change the air outlet direction and air volume of the auxiliary air outlet 322, so as to direct the air exhausted by the air conditioning system 1000 to the target area inside the vehicle.

[0059] The second motor 700 mentioned here can be a rotary motor or a linear motor, etc.

[0060] In some embodiments, users can select "AUTO" mode via the central control panel or select an area where no airflow is directed via an image to adjust the airflow to be uniform throughout the vehicle or to provide localized airflow, in order to meet the comfort needs of different occupants.

[0061] In some embodiments, combined with Figure 1 and Figure 2 As shown, the purification module 200 is a room temperature catalyst filter 210 and / or a first room temperature catalyst element 220. This means that the purification module 200 is a room temperature catalyst filter 210; or, the purification module 200 is a first room temperature catalyst element 220; or, the purification module 200 is both a room temperature catalyst filter 210 and a first room temperature catalyst element 220.

[0062] in, Figure 1 The purification module 200 is shown to be a room temperature catalyst filter 210. Figure 2 The purification module 200 is shown as a first ambient temperature catalyst element 220. In some other embodiments, the purification module 200 can be both an ambient temperature catalyst filter 210 and a first ambient temperature catalyst element 220 (not shown in the figure). The combination of the ambient temperature catalyst filter 210 and the first ambient temperature catalyst element 220 can significantly improve the deodorization efficiency.

[0063] It is worth noting that both the ambient temperature catalyst filter 210 and the first ambient temperature catalyst element 220 of this application use ambient temperature catalysts. Ambient temperature catalysts refer to catalysts that can efficiently promote chemical reactions under ambient temperature (usually between 0°C and 50°C). They break the dependence of traditional catalysts (which require hundreds of degrees Celsius to work) on high temperature and high pressure conditions. This allows the purification module 200 to realize or accelerate specific reactions under mild conditions without relying on any heating element. This not only allows the purification module 200 to be used in the air conditioning system 1000 and ensures the working performance of the purification module 200, but also significantly reduces the energy consumption of the air conditioning system 1000.

[0064] In some embodiments, the ambient temperature catalyst filter 210 includes a frame and a second ambient temperature catalyst element. The frame has a porous structure and is fixedly connected to the inner wall of the main air duct 131 and / or the inner wall of the air supply duct 300. The second ambient temperature catalyst element is disposed on the frame. This means that when the ambient temperature catalyst filter 210 is disposed within the main air duct 131, the frame of the ambient temperature catalyst filter 210 is disposed on the inner wall of the main air duct 131; when the ambient temperature catalyst filter 210 is disposed within the air supply duct 300, the frame of the ambient temperature catalyst filter 210 is disposed on the inner wall of the air supply duct 300. This reduces the difficulty of fixing the frame, facilitates improved positional stability of the frame, thereby enhancing the positional stability of the ambient temperature catalyst filter 210 and ensuring its working performance.

[0065] Meanwhile, by placing the second ambient temperature catalyst on the frame, the frame can be used to support the second ambient temperature catalyst, thereby improving the positional stability of the second ambient temperature catalyst and ensuring its working performance.

[0066] In some embodiments, a room-temperature photocatalyst can be sprayed onto the skeleton to form a second room-temperature catalyst element. Spraying the second room-temperature catalyst element onto the skeleton also facilitates the formation of a uniform catalyst layer.

[0067] In addition, by making the frame a porous structure, the airflow of the air conditioning system 1000 is improved, thus avoiding obstruction of airflow.

[0068] In some embodiments, the frame is made of aluminum. Firstly, aluminum has excellent thermal conductivity, which can quickly and evenly dissipate heat on the frame, achieving uniform heat distribution, so as to uniformly activate the catalyst and improve the purification effect of the purification module 200; secondly, aluminum has low density, which can reduce the weight of the catalyst filter 210 at room temperature.

[0069] Of course, in other embodiments, the skeleton may also be made of other materials, and no specific restrictions are made here.

[0070] In some embodiments, the second room-temperature catalyst is made of at least one of titanium dioxide (TiO2), zinc oxide (ZnO), copper oxide (CuO), and N-doped carbon materials. The catalysts described above have at least the following advantages: first, they do not participate in chemical reactions, are effective for a long time, and do not cause secondary pollution; second, they maintain high activity even in high-humidity environments with relative humidity above 80%; and third, they are low-cost and have good stability, thus ensuring the working performance of the second room-temperature catalyst.

[0071] In some embodiments, the second ambient temperature catalyst element may be made of at least two of titanium dioxide (TiO2), zinc oxide (ZnO), copper oxide (CuO), and N-doped carbon materials. That is, the second ambient temperature catalyst element is formed as a composite catalyst. The composite catalyst can broadly degrade volatile organic compounds that make up the odor in the vehicle, covering formaldehyde, benzene, xylene, acetic acid, ammonia, hydrocarbons, and nitrogen-containing / halogenated organic compounds, etc., to further improve the working performance of the second ambient temperature catalyst element.

[0072] In a specific example, the second ambient temperature catalyst generates highly active electrons (e) on its surface under light excitation. - )-hole (h + Yes, hole (h) +It can directly oxidize water molecules (H2O) adsorbed on the surface of the catalyst to generate hydroxyl radicals (-OH) with extremely strong oxidizing power. The hydroxyl radicals can non-selectively attack the chemical bonds such as C and CH in organic pollutant molecules, gradually oxidizing and decomposing them, and finally mineralizing them into carbon dioxide (CO2) and water (H2O) to achieve the purpose of direct catalytic decomposition of odors.

[0073] Optionally, the first ambient temperature catalyst element 220 is disposed on the inner wall surface of the main air duct 131 and / or the inner wall surface of the air supply duct 300. This means that when the first ambient temperature catalyst element 220 is disposed within the main air duct 131, it is disposed on the inner wall surface of the main air duct 131; when the first ambient temperature catalyst element 220 is disposed within the air supply duct 300, it is disposed on the inner wall surface of the air supply duct 300. This not only avoids the first ambient temperature catalyst element 220 affecting airflow and wind resistance, but also allows the first ambient temperature catalyst element 220 to have a larger contact area with air, thereby improving catalytic efficiency.

[0074] In specific examples, such as Figure 2 As shown, when both the main air duct 131 and the air supply duct 300 are equipped with a first ambient temperature catalyst 220, the first ambient temperature catalyst 220 in the main air duct 131 is located on the inner wall of the main air duct 131, and the first ambient temperature catalyst 220 in the air supply duct 300 is located on the inner wall of the air supply duct 300. The first ambient temperature catalyst 220 in the main air duct 131 is located near the first air outlet 1311 of the air conditioning assembly 100.

[0075] In some embodiments, the main material of the inner wall of the main air duct 131 and the inner wall of the air supply duct 300 is PP (polypropylene). Therefore, a room temperature catalyst coating can be uniformly applied to the inner wall surface of the main air duct 131 and / or the inner wall surface of the air supply duct 300 to realize the setting of the first room temperature catalyst component 220 on the inner wall surface of the main air duct 131 and / or the inner wall surface of the air supply duct 300, and reduce the difficulty of fixing the first room temperature catalyst component 220.

[0076] The first ambient temperature catalyst element 220 can also be prepared by spraying, impregnation and melting or integral carrier processes to ensure a firm bond between the first ambient temperature catalyst element 220 and the inner wall surface of the main air duct 131 and / or the inner wall surface of the air supply duct 300.

[0077] Optionally, the first room-temperature catalyst element 220 is made of at least one of manganese-based metal oxides, manganese-cerium composite oxides (Mn-Ce-O composite oxides), and platinum-based nanocatalysts (Pt-based nanocatalysts) to ensure the working performance of the first room-temperature catalyst element 220.

[0078] Taking manganese-based metal oxides as an example, manganese-based metal oxides utilize variable valence active sites (such as Mn³) on their surface. + / Mn 4+ The catalytic degradation of formaldehyde by hydroxyl (-OH) is as follows: formaldehyde molecules are first adsorbed and activated at the active site and react with surface hydroxyl groups to generate formate intermediates; subsequently, with the participation of gaseous oxygen (O2), the intermediates are further deeply oxidized and finally completely mineralized into carbon dioxide (CO2) and water (H2O) to achieve the purpose of direct catalytic decomposition of odors.

[0079] In some embodiments, combined with Figure 2 , Figure 3 and Figure 4 As shown, grooves 310 are provided on the inner wall surfaces of the main air duct 131 and / or the air supply duct 300, and at least a portion of the first ambient temperature catalyst element 220 is embedded in the grooves 310. This increases the contact area between the first ambient temperature catalyst element 220 and the inner wall surfaces of the main air duct 131 and / or the air supply duct 300, achieving a tight bond between the first ambient temperature catalyst element 220 and the inner wall surfaces of the main air duct 131 and / or the air supply duct 300, preventing the first ambient temperature catalyst element 220 from falling off or being secondary contaminated during long-term operation, thereby ensuring the working performance of the first ambient temperature catalyst element 220.

[0080] In a specific example, the inner wall surfaces of the main air duct 131 and / or the air supply duct 300 can be pre-treated to increase the roughness of the inner wall surfaces of the main air duct 131 and / or the air supply duct 300, thereby achieving the provision of grooves 310 on the inner wall surfaces of the main air duct 131 and / or the air supply duct 300, which also facilitates the realization of "mechanical interlock" between the first ambient temperature catalyst component 220 and the inner wall surfaces of the main air duct 131 and / or the air supply duct 300.

[0081] In some embodiments, such as Figure 1 As shown, the air conditioning system 1000 also includes an ultraviolet lamp assembly 400. The purification module 200 consists of a room-temperature catalyst filter 210 and / or a first room-temperature catalyst element 220. The ultraviolet lamp assembly 400 is positioned close to the purification module 200 and is configured to emit ultraviolet light to irradiate the purification module 200. In other words, the ultraviolet lamp assembly 400 emits ultraviolet light to irradiate the room-temperature catalyst filter 210 and / or the first room-temperature catalyst element 220, thereby activating the catalyst, enhancing the purification effect of the purification module 200, and achieving highly efficient oxidation and deodorization within the air conditioning system 1000 without the need for an external aerodynamic device.

[0082] Meanwhile, the UV lamp assembly 400 can directly sterilize and disinfect itself, thereby improving the purification effect of the air conditioning system 1000.

[0083] In a specific example, when the ultraviolet light emitted by the ultraviolet lamp assembly 400 irradiates the room temperature catalyst filter 210 and / or the first room temperature catalyst element 220, it will stimulate the generation of hydroxyl radicals and superoxide anions with strong oxidizing properties, thereby activating the catalyst and enabling the purification module 200 to achieve efficient catalytic purification.

[0084] When the ambient temperature catalyst filter 210 and / or the first ambient temperature catalyst element 220 are activated by ultraviolet light, the strong oxidizing free radicals generated can non-selectively oxidize and decompose the organic pollutants and some inorganic substances attached to their surface into harmless carbon dioxide and water, so as to achieve the purpose of direct catalytic decomposition of odors.

[0085] In summary, this application achieves a compact, low-power, and easy-to-maintain cabin air purification technology by directly arranging a room-temperature catalyst (room-temperature catalyst filter 210 and / or first room-temperature catalyst component 220) and an ultraviolet lamp assembly 400 within the air conditioning system 1000. This ensures the continuous and efficient photocatalytic reaction while significantly reducing the overall energy consumption of the air conditioning system 1000.

[0086] It should be noted that when the air conditioning system 1000 is not equipped with the ultraviolet lamp component 400 and the purification module 200 is needed to remove gaseous pollutants from the air, the air outlet speed of the air conditioning system 1000 can be automatically reduced to prolong the residence time of the air in the main air duct 131 and the supply air duct 300, thereby prolonging the residence time of the air on the surface of the ambient temperature catalyst filter 210 and / or the first ambient temperature catalyst component 220, enhancing the contact between the gas and the catalyst, and achieving efficient photocatalytic degradation.

[0087] In a specific example, the fan speed of the air conditioning system 1000 can be automatically adjusted, such as reducing the fan speed of the air conditioning system 1000 from level 5 to level 3, so as to reduce the air output speed of the air conditioning system 1000.

[0088] In some embodiments, combined with Figure 1 , Figure 5 and Figure 6As shown, the ultraviolet lamp assembly 400 includes a base 410 and a light-emitting element 420. The base 410 is fixedly connected to the inner wall of the main air duct 131 and / or the inner wall of the air supply duct 300. The light-emitting element 420 is disposed on the base 410 and is configured to emit ultraviolet light. The fixed connection between the base 410 and the inner wall of the main air duct 131 and / or the inner wall of the air supply duct 300 means that when the ultraviolet lamp assembly 400 is disposed within the main air duct 131, the base 410 of the ultraviolet lamp assembly 400 is fixedly connected to the inner wall of the main air duct 131; when the ultraviolet lamp assembly 400 is disposed within the air supply duct 300, the base 410 of the ultraviolet lamp assembly 400 is fixedly connected to the inner wall of the air supply duct 300; when the main air duct 131 and the air supply duct 300 are both located within the main air duct 131, the base 410 of the ultraviolet lamp assembly 400 is fixedly connected to the inner wall of the air supply duct 300; and when the main air duct 131 and the air supply duct 300 are both located within the main air duct 131, the base 410 of the ultraviolet lamp assembly 400 is fixedly connected to the inner wall of the air supply duct 300. When UV lamp assemblies 400 are installed in all 300, the base 410 of the UV lamp assembly 400 in the main air duct 131 is fixedly connected to the inner wall of the main air duct 131, and the base 410 of the UV lamp assembly 400 in the air supply duct 300 is fixedly connected to the inner wall of the air supply duct 300. This reduces the difficulty of fixing the UV lamp assembly 400, facilitates the improvement of the positional stability of the UV lamp assembly 400, and thus ensures the working performance of the UV lamp assembly 400.

[0089] It should be noted that the fixed connection here can be a snap-fit, bolt connection, adhesive bonding, or welding, etc.

[0090] Meanwhile, by placing the light-emitting element 420 on the base 410, the base 410 can support the light-emitting element 420, thereby improving the positional stability of the light-emitting element 420. By configuring the light-emitting element 420 to emit ultraviolet light, ultraviolet light can be used to irradiate the room temperature catalyst filter 210 and / or the first room temperature catalyst element 220, thereby activating the catalyst and improving the purification effect of the purification module 200.

[0091] Optionally, such as Figure 5 As shown, the base 410 has a porous structure. This prevents the base 410 from obstructing airflow and improves the air supply effect of the air conditioning system 1000.

[0092] Optionally, the base 410 is made of aluminum. Firstly, aluminum has excellent thermal conductivity, which can quickly and evenly dissipate heat on the base 410, avoiding local overheating and extending the life of the base 410. Secondly, aluminum has a high reflectivity to ultraviolet light, which can reflect ultraviolet light that is not directly absorbed by the catalyst back to the purification module 200 or adjacent areas, forming secondary irradiation and improving the utilization rate of light energy. Thirdly, aluminum has a low density, which can reduce the weight of the ultraviolet lamp assembly 400.

[0093] Of course, in other embodiments, the base 410 may also be made of other materials, and no specific restrictions are made here.

[0094] In some embodiments, the base 410 has length and width dimensions of 200mm × 200mm.

[0095] Of course, in some other embodiments, the specific dimensions of the base 410 can be adapted to different vehicle models.

[0096] Optionally, the light-emitting element 420 includes at least one UVC band light-emitting chip and at least one UVA band light-emitting chip. The emission wavelength of the UVC band light-emitting chip is 200nm~280nm, and the emission wavelength of the UVA band light-emitting chip is 315nm~400nm. This allows the light-emitting element 420 to be formed as a dual-band ultraviolet lamp strip, wherein the UVC band light-emitting chip is mainly used for efficient sterilization, and the UVA band light-emitting chip is mainly used to activate the room-temperature catalyst and generate a photocatalytic effect, thereby broadening the spectral response, exciting multiple catalysts, and improving the working performance of the ultraviolet lamp assembly 400.

[0097] In some embodiments, a eutectic process can be used to integrate UVC band light-emitting chips and UVA band light-emitting chips onto the base 410. Eutectic technology can improve the stability and lifespan of the light-emitting element 420.

[0098] In some embodiments, combined with Figure 1 and Figure 6 As shown, the purification module 200 is a room-temperature catalyst filter 210. In the airflow direction, the ultraviolet lamp assembly 400 is positioned opposite to the room-temperature catalyst filter 210. The ultraviolet lamp assembly 400 includes a light-emitting element 420, and the minimum distance between the light-emitting element 420 and the room-temperature catalyst filter 210 is 3mm~7mm. Here, the minimum distance between the light-emitting element 420 and the room-temperature catalyst filter 210 can be understood as... Figure 6 The H shown is to ensure that the ultraviolet light emitted by the light-emitting element 420 can radiate uniformly, thereby accelerating the photocatalytic reaction.

[0099] In specific examples, the minimum distance between the light-emitting element 420 and the room-temperature catalyst filter 210 is 3mm, 4mm, 5mm, 6mm or 7mm, etc.

[0100] Optionally, such as Figure 1 As shown, the room-temperature catalyst filter 210 is located upstream of the ultraviolet lamp assembly 400. It should be noted that dust, lint, and other particulate matter in the air can adhere to the quartz glass surface of the ultraviolet lamp assembly 400, forming a layer of dirt film. This film will severely block and scatter ultraviolet rays, causing a sharp decrease in the intensity of ultraviolet rays irradiating the surface of the room-temperature catalyst filter 210, thereby significantly reducing the photocatalytic efficiency.

[0101] Based on this, this application places the ambient temperature catalyst filter 210 upstream of the ultraviolet lamp assembly 400, so that the ultraviolet lamp assembly 400 is placed after the ambient temperature catalyst filter 210. This ensures that the air flowing towards the ultraviolet lamp assembly 400 can first flow to the ambient temperature catalyst filter 210, which purifies the air to prevent dust, lint, and other particulate matter in the air from adhering to the quartz glass surface of the ultraviolet lamp assembly 400, thereby avoiding a reduction in the ultraviolet intensity of the ultraviolet lamp assembly 400. This ensures that the ultraviolet rays irradiated onto the ambient temperature catalyst filter 210 always maintain a high intensity.

[0102] In some embodiments, the overall thickness of the combined ambient temperature catalyst filter 210 and UV lamp assembly 400 is approximately 35 mm.

[0103] Of course, in some other embodiments, the specific dimensions of the combination of the ambient temperature catalyst filter 210 and the ultraviolet lamp assembly 400 can be adapted to different vehicle models.

[0104] Optionally, combined Figure 1 and Figure 6 As shown, light blocking elements 500 are provided between the base 410 and the inner wall of the main air duct 131 and / or the inner wall of the air supply duct 300, as well as between the ambient temperature catalyst filter 210 and the inner wall of the main air duct 131 and / or the inner wall of the air supply duct 300. The light blocking elements 500 are configured to prevent ultraviolet light emitted by the light-emitting element 420 from leaking into non-target areas. This means that when the ambient temperature catalyst filter 210 and the ultraviolet lamp assembly 400 are located in the main air duct 131, light blocking components 500 are provided between the base 410 and the inner wall of the main air duct 131, as well as between the ambient temperature catalyst filter 210 and the inner wall of the main air duct 131; when the ambient temperature catalyst filter 210 and the ultraviolet lamp assembly 400 are located in the air supply duct 300, light blocking components 500 are provided between the base 410 and the inner wall of the air supply duct 300, as well as between the ambient temperature catalyst filter 210 and the inner wall of the air supply duct 300, to ensure that ultraviolet light can effectively and abundantly irradiate the ambient temperature catalyst filter 210, avoid ultraviolet light leakage, and improve the purification effect of the purification module 200.

[0105] In some embodiments, the light blocking component 500 is a UV-blocking acrylic sheet, and the surface of the UV-blocking acrylic sheet is coated with a black matte layer so that the transmittance of the light blocking component 500 is less than 1%, thereby enabling the light blocking component 500 to effectively prevent the ultraviolet light emitted by the light-emitting component 420 from leaking into non-target areas.

[0106] In specific examples, such as Figure 1As shown, the air conditioning system 1000 includes an ultraviolet lamp assembly 400 and a purification module 200, which is a room temperature catalyst filter 210. The ultraviolet lamp assembly 400 and the room temperature catalyst filter 210 are arranged opposite to each other and are both located in the main air duct 131. With the above arrangement, when air purification is required, the ultraviolet lamp assembly 400 can be activated to emit ultraviolet light to irradiate the purification module 200, thereby activating the room temperature catalyst filter 210 to purify the air and achieve efficient catalytic purification.

[0107] In other embodiments, such as Figure 2 As shown, the air conditioning system 1000 does not have an ultraviolet lamp assembly 400. The purification module 200 is a first ambient temperature catalyst 220. When both the main air duct 131 and the air supply duct 300 are equipped with the first ambient temperature catalyst 220, the first ambient temperature catalyst 220 in the main air duct 131 is located on the inner wall of the main air duct 131, and the first ambient temperature catalyst 220 in the air supply duct 300 is located on the inner wall of the air supply duct 300. The first ambient temperature catalyst 220 in the main air duct 131 is located close to the first air outlet 1311 of the air conditioning assembly 100. With the above arrangement, when air purification is required, the air outlet velocity of the air conditioning system 1000 can be automatically reduced to prolong the residence time of the air on the surface of the first ambient temperature catalyst 220, enhance the contact between the gas and the catalyst, and achieve efficient photocatalytic degradation.

[0108] It should be noted that the solution without the UV lamp assembly 400 has a simple structure. It only requires one-time treatment of the inner walls of the main air duct 131 and the air supply duct 300, which can significantly increase the contact area between the catalyst and the airflow and improve the overall purification efficiency. At the same time, because it does not occupy extra space, it can flexibly adapt to the installation requirements of different vehicle models.

[0109] In some embodiments, such as Figure 1 and Figure 2 As shown, the air conditioning system 1000 also includes an air quality sensor 600 and a control unit. Both the air quality sensor 600 and the ultraviolet lamp assembly 400 are connected to the control unit. The air quality sensor 600 is configured to monitor air odor and gaseous pollutants. This allows for closed-loop control of "odor perception (air quality sensor 600) - photocatalysis (ultraviolet lamp assembly 400)" using the air quality sensor 600 and the ultraviolet lamp assembly 400, thereby achieving intelligent, on-demand, and precise odor removal.

[0110] In some embodiments, the control unit is configured to: Activate the monitoring function of the air quality sensor 600; Based on the monitoring data from the air quality sensor 600, determine whether to control the start / stop of the ultraviolet lamp assembly 400 and / or adjust the fan speed of the air conditioning system 1000.

[0111] In other words, this application controls the start / stop of the ultraviolet lamp assembly 400 and / or adjusts the fan speed of the air conditioning system 1000 based on the monitoring data of the air quality sensor 600, so as to realize intelligent on-demand response to odor perception and photocatalysis closed-loop management, avoid the ultraviolet lamp assembly 400 being constantly on and increasing power consumption, and at the same time avoid the air conditioning system 1000 being in a low-speed state and unable to meet the cooling and heating requirements, so as to improve the performance of the air conditioning system 1000.

[0112] It should be noted that the principle of the air quality sensor 600 generating electrical signals is as follows: when the target reducing gas (VOCs) molecules diffuse to the material surface of the air quality sensor 600, they undergo a catalytic oxidation-reduction reaction with oxygen negative ions. The electrons released by the reaction are fed back to the semiconductor conduction band, thereby reducing the material resistance. The gas concentration is positively correlated with the reaction rate. Therefore, the decrease in semiconductor resistance is a function of the target gas concentration, thereby realizing the detection of gas concentration.

[0113] In some embodiments, the air quality sensor 600 includes at least one of an electrochemical sensor, a metal oxide semiconductor sensor, a photoionization detector, and a catalytic combustion sensor. This enables the air quality sensor 600 to produce specific responses to gases such as aldehydes, benzenes, amines, and sulfur, thereby improving the performance of the air quality sensor 600.

[0114] In a specific example, the air quality sensor 600 includes an electrochemical sensor, a metal oxide semiconductor sensor, a photoionization detector, and a catalytic combustion sensor, forming an array sensor. The electrochemical sensor, metal oxide semiconductor sensor, photoionization detector, and catalytic combustion sensor are interconnected with the PCB, supporting odor learning and tagging. When a predefined odor is detected, a signal is sent to the control unit to trigger the operation of the ultraviolet lamp assembly 400 or automatically change the airflow level, etc.

[0115] Optionally, such as Figure 1 and Figure 2 As shown, the air quality sensor 600 is positioned near the first air outlet 1311 of the air conditioning assembly 100. This allows the air flowing through the first air outlet 1311 to be effectively detected by the air quality sensor 600, facilitating effective monitoring of odors within the air conditioning assembly 100 and enabling subsequent odor purification treatment.

[0116] Of course, in other embodiments, the air quality sensor 600 may be installed in other locations inside the vehicle depending on space and requirements, and no specific restrictions are imposed here.

[0117] In summary, this application integrates a room-temperature catalytic filter 210, an ultraviolet lamp assembly 400, and an air quality sensor 600 within the housing 130 of the air conditioning assembly 100, or integrates a first room-temperature catalytic element 220 within the air supply duct 300, forming an integrated, multi-layered, all-round, and low-energy-consumption cabin air purification unit. This unit can achieve photocatalytic reaction with low power consumption without relying on additional heating elements or aerodynamic components, thereby significantly reducing the energy consumption of the air conditioning system 1000. Simultaneously, the synergistic effect of photocatalysis and ultraviolet light greatly enhances the decomposition rate of odors and gaseous pollutants, enabling the complete decomposition of gaseous pollutants and odor molecules in the cabin into harmless gases. This overcomes the technical difficulties of existing air conditioning assemblies 100, such as the air conditioning filter 180's inability to effectively remove odors from the evaporator 110, and the high energy consumption caused by the catalytic purification device's reliance on heating elements or additional power units. Furthermore, this technology is compact, easy to maintain, and highly adaptable, meeting the urgent needs of modern automobiles for a healthy and comfortable in-vehicle environment.

[0118] In some embodiments, the control unit is configured to: Before activating the monitoring function of the air quality sensor 600, identify the type of trigger command received; If the trigger command is identified as a first type of command, the first control logic is executed: the air conditioning system 1000 is switched to the internal circulation mode, the air quality sensor 600 is activated to monitor, and the control of the ultraviolet lamp assembly 400 and / or the fan speed of the air conditioning system 1000 is determined based on the monitoring data. If the trigger command is identified as a second type of command, the second control logic is executed: first, the ultraviolet lamp assembly 400 is activated and / or the fan speed of the air conditioning system 1000 is adjusted, and then the air quality sensor 600 is activated for monitoring.

[0119] The first type of instruction includes vehicle start signal or air conditioning system 1000 start signal, and the second type of instruction is the instruction for the user to actively turn on the purification function.

[0120] In other words, when the trigger command is a vehicle start signal or an air conditioning system 1000 start signal, the air conditioning system 1000 is first controlled to switch to internal circulation mode to ensure the cooling and heating effect of the air conditioning system 1000. Since it is impossible to determine whether air purification is needed at this time, the air quality sensor 600 is first activated to monitor. Then, based on the monitoring data, it is determined whether to activate and control the ultraviolet lamp component 400 and / or adjust the fan speed of the air conditioning system 1000, so as to realize intelligent on-demand response to closed-loop management of odor perception and photocatalysis.

[0121] Meanwhile, when the trigger command is a user-initiated command to activate the purification function, indicating that air purification is required, the UV lamp component 400 will be activated first and / or the fan speed of the air conditioning system 1000 will be adjusted, followed by the activation of the air quality sensor 600 for monitoring.

[0122] In some embodiments, the control unit is configured to: Based on the monitoring data from the air quality sensor 600, determine whether a preset scenario occurs inside the vehicle; If so, activate the UV lamp assembly 400 to emit UV light to irradiate the purification module 200 and / or reduce the fan speed of the air conditioning system 1000.

[0123] In other words, after the air quality sensor 600 is activated, it is also necessary to determine whether a preset scenario occurs in the vehicle based on the monitoring data of the air quality sensor 600. This enables precise control of the start / stop of the ultraviolet lamp assembly 400 and / or adjustment of the air conditioning system 1000's fan speed, achieving on-demand and precise odor removal. At the same time, it avoids the ultraviolet lamp assembly 400 being constantly on, which would increase power consumption, and the air conditioning system 1000's fan speed being reduced, which would fail to meet the cooling and heating requirements.

[0124] In some embodiments, the ultraviolet lamp assembly 400 can automatically adjust the light intensity and irradiation duration based on the odor intensity detected by the air quality sensor 600, thereby achieving a closed-loop control of "odor perception-photocatalysis".

[0125] Optionally, the control unit is configured to: in the step of determining whether a preset scenario occurs inside the vehicle, invoke the signal processing and data classification analysis module to process, classify, and perform pattern recognition on the monitoring data of the air quality sensor 600, in order to identify a specific scenario including at least one of the following: a musty odor scenario generated by the evaporator 110, a strong odor scenario caused by residues inside the vehicle, or a pollution scenario caused by excessive levels of specific gaseous pollutants. This facilitates the purification treatment of the musty odor generated by the evaporator 110, the strong odor caused by residues inside the vehicle, and the specific gaseous pollutants.

[0126] In some embodiments, the control unit is configured to: After activating the UV lamp assembly 400 and / or reducing the fan speed of the air conditioning system 1000, the system continues to determine whether a preset scenario occurs inside the vehicle based on the continuous monitoring data from the air quality sensor 600. If not, then control the UV lamp assembly 400 to turn off and / or increase the fan speed of the air conditioning system 1000, and control the air quality sensor 600 to turn off.

[0127] The above steps can avoid increasing power consumption due to the UV lamp component 400 being constantly on, and prevent the air conditioning system 1000 from reducing its fan speed and failing to meet cooling and heating requirements.

[0128] Optionally, the control unit is configured to: if the trigger command is identified as a first type of command, control the ultraviolet lamp assembly 400 to turn off and / or increase the fan speed of the air conditioning system 1000 and control the air quality sensor 600 to turn off, and then reduce the air intake volume at the external circulation air intake 152 of the air conditioning system 1000.

[0129] In other words, when the triggering command is a vehicle start signal or an air conditioning system 1000 start signal and the air inside the vehicle does not need to be purified, the air intake at the external circulation air intake 152 of the air conditioning system 1000 is reduced in order to accelerate the cooling and heating of the air conditioning system 1000 and to allow fresh air to be delivered to every corner of the passenger compartment.

[0130] In some embodiments, when the air conditioning system 1000 is used in a vehicle, the external air intake 152 is located at the lower right corner of the junction of the vehicle's engine compartment and windshield (below the wiper bracket on the passenger side), and uses a mesh plastic cover to prevent rainwater from entering directly and to facilitate the removal of leaves and debris.

[0131] It should be noted that the function of the external air intake 152 is to draw in fresh air from outside the vehicle, reduce the concentration of carbon dioxide in the cabin to prevent oxygen deficiency, and introduce dry air to quickly defog.

[0132] In some embodiments, combined with Figure 1 and Figure 2 As shown, the air conditioning assembly 100 also includes an internal circulation air intake 151. When the air conditioning system 1000 is used in a vehicle, the internal circulation air intake 151 is embedded behind or below the glove box on the passenger side. It is responsible for drawing in the existing air in the cabin and entering the air conditioning system 1000 to achieve air circulation and prevent external exhaust gas, dust and other pollutants from entering.

[0133] In some embodiments, combined with Figure 1 and Figure 2 As shown, the air conditioning assembly 100 also includes a controllable door 160 and a third motor 171. The controllable door 160 is an arc-shaped baffle driven by the third motor 171. The controllable door 160 is located at the intersection of the internal circulation air inlet 151 and the external circulation air inlet 152, forming an actuator for switching between internal and external circulation.

[0134] The third motor 171 mentioned here can be a rotary motor or a linear motor, etc.

[0135] In the description of this invention, features defined as "first," "second," and "third" may explicitly or implicitly include one or more of these features, used to distinguish and describe features, without any order or emphasis.

[0136] In some embodiments, when the air conditioning system 1000 is used in a vehicle, the user can select “AUTO”, “RECIRC” or “VENT” mode on the center console to switch between external and internal air circulation. At this time, the air conditioning system 1000 can automatically switch according to parameters such as ambient temperature and set temperature to maintain optimal comfort and air quality.

[0137] In summary, this application purifies in-vehicle odors and gaseous pollutants, and provides a closed-loop management and control strategy of "odor perception-photocatalysis" to achieve intelligent, on-demand and precise odor removal, thereby achieving long-lasting and comprehensive air purification in the vehicle cabin. It can simultaneously remove odors, gaseous pollutants and microorganisms, etc., and improve the user experience.

[0138] In a specific example, this application utilizes an air quality sensor 600 to collect odor data from the first air outlet 1311 in real time, thereby monitoring odors generated within the air conditioning system 1000. The application also uses a pre-trained machine learning model to identify and determine features. When a preset odor scenario is detected, the closed-loop control unit instantly drives the ultraviolet lamp assembly 400 to work or adjusts the air conditioning system 1000's fan speed, achieving intelligent, on-demand response to odor perception and photocatalysis in a closed-loop management system, thus achieving intelligent, on-demand, and precise odor removal.

[0139] Meanwhile, compared to existing deodorization systems that keep the monitoring function on all the time or turn it off after a certain period of time, the intelligent control of this application can significantly reduce power consumption, avoid energy waste and non-targeted deodorization caused by false alarms / missed alarms, thereby reducing the overall deodorization power consumption of this application by about 80% to 95% compared to traditional full-time operation.

[0140] In some embodiments, combined with Figure 1 and Figure 2 As shown, the air conditioning assembly 100 also includes a blower 190, which is the core driving component of the air conditioning assembly 100. It is mainly used to drive air through the external or internal circulation path, and pushes the air through the evaporator 110 when cooling and pushes the air through the heater 140 when heating.

[0141] Optionally, the speed of the blower 190 can be adjusted via the central control panel. When the air conditioning system 1000 is used in the vehicle, the blower 190 is hidden behind the passenger glove box or under the dashboard.

[0142] In some embodiments, combined with Figure 1 and Figure 2As shown, the air conditioning assembly 100 also includes an air conditioning filter 180, which is an air purification device. The interior of the air conditioning filter 180 is filled with materials such as activated carbon, molecular sieves, metal-organic frameworks (MOFs) or covalent organic frameworks (COFs) to capture particulate matter such as dust, PM2.5, pollen, and smoke, as well as VOCs, odor molecules, bacteria and mold.

[0143] The activated carbon in the adsorption pack of the air conditioning filter 180 has non-uniform pores, which adsorb both nano-sized VOCs and micron-sized particles. This results in the filter adsorbing more particulate matter in the air during external circulation, which in turn limits the adsorption capacity of the air conditioning filter 180 for odor molecules during internal circulation and makes it easy to become saturated. As a result, the air blown out has an odor and musty smell, and the filter needs to be replaced regularly.

[0144] Therefore, when the air conditioning system 1000 is used in a vehicle, the air conditioning filter 180 is located in front of the blower 190 and installed behind the passenger glove box for easy removal and replacement.

[0145] In summary, in a specific example, the user can set the vehicle to automatically activate the "intelligent purification" function, or actively activate the "intelligent purification" function when a noticeable odor is detected. When the vehicle automatically activates the "intelligent purification" function, the air quality sensor 600 can monitor the gas. The detected odor signal is converted into an electrical signal and transmitted to the signal processing and data classification analysis module. The processing chip and machine learning algorithm determine whether the electrical signal belongs to a preset odor scenario (such as a musty smell, sour smell, residual food smell, fishy smell, or other strong odors). If it is determined to be a preset odor, the ultraviolet lamp component 400 is activated to emit ultraviolet light to irradiate the purification module 200 to excite the room temperature catalyst for photocatalytic purification and / or reduce the fan speed of the air conditioning system 1000. Then, the above monitoring, judgment, and response process is repeated until the preset odor scenario is no longer detected. At that time, the air quality sensor 600 stops monitoring and returns to the initial standby state, and restarts when the "intelligent purification" function is activated again.

[0146] When a user actively activates the "Smart Purification" function upon sensing a noticeable odor, the UV lamp component 400 is directly activated to emit UV light, which irradiates the purification module 200 to excite the room-temperature catalyst for photocatalytic purification and / or reduces the fan speed of the air conditioning system 1000. Subsequently, the air quality sensor 600 is activated to monitor the gas. The detected odor signal is converted into an electrical signal and transmitted to the signal processing and data classification analysis module. The processing chip and machine learning algorithm determine whether the electrical signal belongs to a preset odor scenario (such as a musty smell, sour smell, residual food smell, fishy smell, or other strong odors). If it is determined to be a preset odor, the UV lamp component 400 continues to emit UV light to irradiate the purification module 200 to excite the room-temperature catalyst for photocatalytic purification and / or reduce the fan speed of the air conditioning system 1000. The above monitoring, judgment, and response process is then repeated until the preset odor scenario location can no longer be detected. At this point, the air quality sensor 600 stops monitoring and returns to the initial standby state, restarting when the "Smart Purification" function is activated again.

[0147] It should be noted that the above control strategy can effectively reduce the operating frequency of the ultraviolet lamp assembly 400 in the early stages of new vehicle use. The ultraviolet lamp assembly 400 mainly starts when long-term accumulated odors from the evaporator 110, air conditioning housing 130, and air duct appear in the vehicle (approximately 3 to 6 months after the new vehicle is used), achieving the dual goals of energy saving and efficient purification.

[0148] The control method of the air conditioning system 1000 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0149] Among them, such as Figure 7 As shown, this control method is for a user to start the vehicle, or for a user to remotely turn on the air conditioning ventilation and cooling mode during hot summer days. It includes the following steps: S10. Start the vehicle or remotely turn on the air conditioning ventilation and cooling. S11. The air conditioning internal circulation mode is turned on by default, with the external circulation ventilation volume at 30% (or, according to the "memory" function, it remains in the last state after the engine was turned off); the ventilation damper is opened. In the above steps, by setting the external air circulation volume to 30%, it is possible to ensure rapid cooling of the vehicle interior while introducing fresh air and quickly expelling stale air.

[0150] S12. Activate the monitoring function of the air quality sensor 600; During the above steps, the vehicle automatically activates the "intelligent purification" function.

[0151] In a specific example, air flows from the internal circulation air inlet 151 and the external circulation air inlet 152 through the main air duct 131 to the main air outlet 321, and the air quality sensor 600 monitors the air odor and gaseous pollutants.

[0152] S13. Call the signal processing and data classification analysis module to process, classify and pattern recognize the monitoring data of the air quality sensor 600; In the above steps, the main process is that the air quality sensor 600 chip preprocesses the electrical signals and the machine learning algorithm in the module classifies and analyzes the data.

[0153] S14. Determine if a preset scene appears inside the vehicle; The above steps mainly determine whether the electrical signal belongs to a preset odor scenario. The preset odor scenarios include a musty odor scenario generated by the evaporator 110, a strong odor scenario caused by residues in the vehicle, or a pollution scenario caused by excessive levels of specific gaseous pollutants.

[0154] Among them, the preset odor scenario can also be a sour smell scenario generated by the evaporator 110; the strong odor scenario caused by residues in the vehicle can be a strong odor such as residual food smell or fishy smell; specific gaseous pollutants include formaldehyde, toluene or TVOC (Total Volatile Organic Compounds).

[0155] S15. If it is determined that a preset scene occurs in the vehicle, that is, there is a preset odor or gaseous pollutant in the vehicle, the ultraviolet lamp assembly 400 is activated to emit ultraviolet light to irradiate the purification module 200 and / or the air conditioning system 1000 is reduced. Specifically, activating the ultraviolet lamp assembly 400 to emit ultraviolet light to irradiate the purification module 200 can stimulate the ambient temperature catalyst filter 210 and / or the first ambient temperature catalyst element 220 to purify the air; reducing the airflow speed of the air conditioning system 1000 can increase the contact time between the catalyst and the airflow, thereby improving the overall purification efficiency.

[0156] In a specific example, after the external circulating air enters the main air duct 131, it passes through the evaporator 110. The ventilation damper is used to prevent condensate from directly entering the catalytic zone. The ambient temperature catalyst filter 210 and / or the first ambient temperature catalyst element 220 catalyze and purify the air under the excitation of ultraviolet light.

[0157] Meanwhile, after activating the UV lamp assembly 400 and / or reducing the fan speed of the air conditioning system 1000, the air quality sensor 600 continuously monitors air odor and gaseous pollutants. If there is an odor, the "intelligent purification" function will continue to be activated.

[0158] S16. If it is determined that the preset scenario does not occur inside the vehicle, control the air quality sensor 600 to turn off; In other words, the air quality sensor 600 will be turned off once it detects no odor.

[0159] It should be noted that when the UV lamp assembly 400 is activated and the air conditioning system 1000's fan speed is reduced, when the air quality sensor 600 is turned off, the UV lamp assembly 400 also needs to be turned off and the air conditioning system 1000's fan speed increased to stop the "intelligent purification" function.

[0160] S17. Reduce the air intake volume at the external circulation air inlet 152 of the air conditioning system 1000.

[0161] This step facilitates faster cooling of the air conditioning system 1000 and allows fresh air to be delivered to every corner of the passenger compartment.

[0162] In a specific example, the air intake volume at the external circulation air intake 152 of the air conditioning system 1000 can be set to 10%.

[0163] S18, Purification mode ends.

[0164] like Figure 8 As shown, this control method is a method for controlling a user to start the vehicle or remotely turn on the air conditioning heating mode during cold winter months, and includes the following steps: S20. Start the vehicle or remotely turn on the air conditioning ventilation and cooling. S21. The air conditioning internal circulation mode is turned on by default, with the external circulation ventilation volume at 30% (or, according to the "memory" function, it remains in the last state after the engine was turned off); the ventilation damper and heating damper are turned on. In the above steps, by setting the external circulation ventilation volume to 30%, the interior of the vehicle can be cooled down quickly, fresh air can be introduced, and polluted air can be expelled quickly. The ventilation damper and heating damper can be opened to obtain the required air outlet temperature.

[0165] S22. Activate the monitoring function of the air quality sensor 600; During the above steps, the vehicle automatically activates the "intelligent purification" function.

[0166] In a specific example, air flows from the internal circulation air inlet 151 and the external circulation air inlet 152 through the main air duct 131 to the main air outlet 321, and the air quality sensor 600 monitors the air odor and gaseous pollutants.

[0167] S23. Call the signal processing and data classification analysis module to process, classify and pattern recognize the monitoring data of the air quality sensor 600; In the above steps, the main process is that the air quality sensor 600 chip preprocesses the electrical signals and the machine learning algorithm in the module classifies and analyzes the data.

[0168] S24. Determine if a preset scene appears inside the vehicle; The above steps mainly determine whether the electrical signal belongs to a preset odor scenario. The preset odor scenarios include a musty odor scenario generated by the evaporator 110, a strong odor scenario caused by residues in the vehicle, or a pollution scenario caused by excessive levels of specific gaseous pollutants.

[0169] Among them, the preset odor scenario can also be a sour smell scenario generated by the evaporator 110; the strong odor scenario caused by residues in the vehicle can be a strong odor such as residual food smell or fishy smell; specific gaseous pollutants include formaldehyde, toluene or TVOC (Total Volatile Organic Compounds).

[0170] S25. If it is determined that a preset scene occurs in the vehicle, that is, there is a preset odor or gaseous pollutant in the vehicle, the ultraviolet lamp assembly 400 is activated to emit ultraviolet light to irradiate the purification module 200 and / or the air conditioning system 1000 is reduced. Specifically, activating the ultraviolet lamp assembly 400 to emit ultraviolet light to irradiate the purification module 200 can stimulate the ambient temperature catalyst filter 210 and / or the first ambient temperature catalyst element 220 to purify the air; reducing the airflow speed of the air conditioning system 1000 can increase the contact time between the catalyst and the airflow, thereby improving the overall purification efficiency.

[0171] In a specific example, after the external circulating air enters the main air duct 131, it passes through the evaporator 110 and the heater 140. The condensate is rapidly evaporated under the action of the heater 140, protecting the catalyst layer from water corrosion. The ambient temperature catalyst filter 210 and / or the first ambient temperature catalyst element 220 catalyze and purify the air under the excitation of ultraviolet light. The residual heat of the air generated by the heater 140 increases the catalytic reaction rate.

[0172] Meanwhile, after activating the UV lamp assembly 400 and / or reducing the fan speed of the air conditioning system 1000, the air quality sensor 600 continuously monitors air odor and gaseous pollutants. If there is an odor, the "intelligent purification" function will continue to be activated.

[0173] S26. If it is determined that the preset scenario does not occur inside the vehicle, control the air quality sensor 600 to turn off; In other words, the air quality sensor 600 will be turned off once it detects no odor.

[0174] It should be noted that when the UV lamp assembly 400 is activated and the air conditioning system 1000's fan speed is reduced, when the air quality sensor 600 is turned off, the UV lamp assembly 400 also needs to be turned off and the air conditioning system 1000's fan speed increased to stop the "intelligent purification" function.

[0175] S27. Reduce the air intake at the external circulation air inlet 152 of the air conditioning system 1000.

[0176] This step facilitates faster heating of the air conditioning system 1000 and allows fresh air to be delivered to every corner of the passenger compartment.

[0177] In a specific example, the air intake volume at the external circulation air intake 152 of the air conditioning system 1000 can be set to 10%.

[0178] S28, Purification mode ends.

[0179] like Figure 9 As shown, this control method automatically activates the "intelligent purification" function when the user perceives an odor inside the vehicle, including the following steps: S30, User-initiated command to activate the purification function; S31. Activate the ultraviolet lamp assembly 400 to emit ultraviolet light to irradiate the purification module 200 and / or reduce the fan speed of the air conditioning system 1000; Specifically, activating the ultraviolet lamp assembly 400 to emit ultraviolet light to irradiate the purification module 200 can stimulate the ambient temperature catalyst filter 210 and / or the first ambient temperature catalyst element 220 to purify the air; reducing the airflow speed of the air conditioning system 1000 can increase the contact time between the catalyst and the airflow, thereby improving the overall purification efficiency.

[0180] In a specific example, after the circulating air enters the main air duct 131, the ventilation damper and heating damper effectively block the condensate, protecting the catalyst layer from water erosion. The ambient temperature catalyst filter 210 and / or the first ambient temperature catalyst element 220 catalyze and purify the air under the excitation of ultraviolet light.

[0181] S32. Activate the monitoring function of the air quality sensor 600; In a specific example, air flows from the internal circulation air inlet 151 and the external circulation air inlet 152 through the main air duct 131 to the main air outlet 321, and the air quality sensor 600 monitors the air odor and gaseous pollutants.

[0182] S33. Call the signal processing and data classification analysis module to process, classify and pattern recognize the monitoring data of the air quality sensor 600; In the above steps, the main process is that the air quality sensor 600 chip preprocesses the electrical signals and the machine learning algorithm in the module classifies and analyzes the data.

[0183] S34. Determine if a preset scene appears inside the vehicle; The above steps mainly determine whether the electrical signal belongs to a preset odor scenario. The preset odor scenarios include a musty odor scenario generated by the evaporator 110, a strong odor scenario caused by residues in the vehicle, or a pollution scenario caused by excessive levels of specific gaseous pollutants.

[0184] Among them, the preset odor scenario can also be a sour smell scenario generated by the evaporator 110; the strong odor scenario caused by residues in the vehicle can be a strong odor such as residual food smell or fishy smell; specific gaseous pollutants include formaldehyde, toluene or TVOC (Total Volatile Organic Compounds).

[0185] S35. If a preset scenario is determined to occur inside the vehicle, that is, a preset odor or gaseous pollutant is present in the vehicle, the ultraviolet lamp assembly 400 continuously emits ultraviolet light to irradiate the purification module 200 and / or maintains a reduced air conditioning system 1000 fan speed. S36. If it is determined that the preset scenario does not occur inside the vehicle, control the air quality sensor 600 to turn off; In other words, the air quality sensor 600 will be turned off once it detects no odor.

[0186] S37. Turn off the UV lamp assembly 400 and / or increase the fan speed of the air conditioning system 1000 to stop the "intelligent purification" function.

[0187] The above steps are to deliver fresh air to every corner of the passenger cabin.

[0188] S38, Purification mode ended.
