Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, and in particular to an air-conditioning air inlet box, an air-conditioning system and a vehicle. Background Art

[0002] In winter when the temperature is low, the air conditioning system of new energy vehicles needs to heat the air in the cabin to provide a warm environment. However, new energy vehicles do not have engines and can only rely on the electricity stored in the battery to heat the air, which consumes a lot of electricity. Therefore, for new energy vehicles, the energy consumption of air conditioning in winter has an impact on their cruising range that cannot be ignored. Especially in extremely cold temperatures, more electricity will be used to heat the air in the air conditioning system instead of driving the vehicle, resulting in increased energy consumption and shorter cruising range for new energy vehicles. It is necessary to make a reasonable trade-off in the design and use of the air conditioning system.

[0003] According to the thermal comfort model, the air conditioning system includes two key heat transfer paths: internal circulation and external circulation. In the cold winter, the internal circulation airflow is usually the air with higher temperature and humidity in the cabin, with higher heat and humidity; the external circulation airflow is usually the air with lower temperature and humidity outside the cabin, which has a higher oxygen concentration, but the air conditioning system needs to consume electricity to heat it before it enters the cabin. Therefore, choosing the internal circulation path can save energy to a greater extent, but due to the high humidity of the air in the internal circulation airflow, long-term use of the internal circulation path is likely to cause fogging of the windows in the cabin. At the same time, the CO2 concentration of the air in the internal circulation airflow is high, which can easily cause the driver to feel sleepy. Therefore, due to these two factors, when the air is introduced into the air conditioning system, it is still necessary to ensure the entry of fresh air to a large extent, sacrificing some energy consumption to control the risk of fogging and health risks.

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0031] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0033] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] In the cold winter, the internal circulation airflow of the air conditioning system is usually the air with higher temperature and humidity in the cabin, with higher heat and humidity; the external circulation airflow is usually the air with lower temperature and humidity outside the cabin, with lower heat and humidity, and higher concentration of oxygen, which is beneficial to improve the freshness of the air in the cabin and is not easy to cause the windows to fog up. However, due to the lower temperature, the air conditioning system needs to consume more electricity to heat it before it enters the cabin. Therefore, choosing the internal circulation path can save energy to a greater extent, but due to the higher humidity of the air in the internal circulation airflow, long-term use of the internal circulation path is likely to cause the windows in the cabin to fog up. At the same time, the CO 2 The high concentration can easily cause fatigue to drivers and passengers. Due to these two factors, the air-conditioning system still needs to ensure the entry of fresh air to a large extent. However, the introduction of more fresh air will inevitably lead to an increase in the energy consumption of the air-conditioning system, and energy consumption needs to be sacrificed to control the risk of fogging and health risks. The problem is not solved from the root, which is not conducive to improving the vehicle's range.

[0035] The utility model proposes a scheme to improve the air inlet box of the air conditioner, which can appropriately increase the proportion of the internal circulation airflow in the total air intake, so as to effectively utilize the heat in the internal circulation airflow and reduce the energy consumption of the air conditioning system in winter when the temperature is low. At the same time, it can also ensure that the air entering the cabin is relatively dry and CO 2 The content is low, which can minimize the fogging of car windows and the drowsiness of passengers, and improve comfort and safety.

[0036] Embodiment 1

[0037] In this embodiment, a single-layer air conditioning air inlet box is used as an example for description. Figure 1 As shown, this embodiment provides an air-conditioning air inlet box, which includes a box body 100, an adsorption device 200, an air-conditioning filter element 300 and a blower 400. The box body 100 is hollow inside to form a ventilation channel, and the box body 100 is provided with an external circulation air inlet 110, an internal circulation air inlet 120 and an air outlet 130, and the air outlet 130 is connected to the air-conditioning distribution box of the air-conditioning system. The external circulation air inlet 110, the internal circulation air inlet 120 and the air outlet 130 are all connected to the ventilation channel, and the external circulation airflow 10 flows into the ventilation channel from the external circulation air inlet 110, and the internal circulation airflow 20 flows into the ventilation channel from the internal circulation air inlet 120. After the external circulation airflow 10 and the internal circulation airflow 20 converge in the ventilation channel, they are sent out from the air outlet 130, and then the air-conditioning distribution box diverts the external circulation airflow 10 and the internal circulation airflow 20 to various positions in the vehicle cabin. The adsorption device 200 is disposed in the housing 100 and is located at the internal circulation air inlet 120. When the internal circulation airflow 20 passes through the adsorption device 200, the adsorption device 200 can adsorb CO in the internal circulation airflow 20. 2 and water, thereby reducing the humidity of the internal circulating airflow 20 entering the ventilation channel, and the CO 2 content, and try to avoid fogging of the car windows and drowsiness of the passengers. The air conditioning filter 300 is arranged in the housing 100 and is located in the ventilation channel. The air conditioning filter 300 is located downstream of the adsorption device 200. The air conditioning filter 300 can adsorb particulate matter in the external circulation airflow 10 and the internal circulation airflow 20. The air conditioning filter 300 can remove dust for the external circulation airflow 10 and the internal circulation airflow 20. The blower 400 is arranged in the housing 100 and is located in the ventilation channel. The blower 400 is located downstream of the air conditioning filter 300. The blower 400 can drive the external circulation airflow 10 and the internal circulation airflow 20 to circulate in the ventilation channel, and send the external circulation airflow 10 and the internal circulation airflow 20 to the air conditioning distribution box.

[0038] That is to say, the air-conditioning air inlet box in this embodiment includes two air inlet paths. One is the external circulation air inlet path, in which the external circulation airflow 10 enters the ventilation channel from the external circulation air inlet 110, and then flows through the air-conditioning filter 300 and the blower 400 in sequence before being sent out from the air outlet 130. The second is the internal circulation air inlet path, in which the internal circulation airflow 20 enters the adsorption device 200 from the internal circulation air inlet 120, and then flows through the air-conditioning filter 300 and the blower 400 in sequence after passing through the adsorption device 200 before being sent out from the air outlet 130. It should be noted that the external circulation airflow 10 and the internal circulation airflow 20 converge in the ventilation channel to form a mixed airflow 30, and then the mixed airflow 30 is driven by the blower 400 to be sent out from the air outlet 130. By arranging the adsorption device 200 in the internal circulation air inlet path, the CO in the internal circulation airflow 20 is reduced. 2The content and water content are reduced, thereby ensuring that the internal circulation airflow 20 can run for a long time when it accounts for a high proportion of the total air intake, and the car windows will not fog up, and the passengers and drivers will not fall asleep and feel sleepy. In addition, since the internal circulation airflow 20 accounts for a high proportion of the total air intake, the heat in the internal circulation can be fully utilized, energy consumption can be reduced, and the problem is solved from the root.

[0039] As an optional solution, in this embodiment, an internal circulation air intake damper 121 and a moisture absorption channel damper 122 are provided at the internal circulation air inlet 120, and the adsorption device 200 is arranged downstream of the moisture absorption channel damper 122. That is, the internal circulation air intake path can be divided into two, one is the internal circulation moisture absorption air intake path, and the other is the internal circulation non-moisture absorption air intake path. In the internal circulation moisture absorption path, the internal circulation airflow 20 passes through the moisture absorption channel damper 122, the adsorption device 200, the air conditioning filter 300 and the blower 400 in sequence. In this path, the adsorption device 200 can absorb CO in the internal circulation airflow 20. 2 and water to reduce the CO in the internal circulating gas stream 20. 2 Content, water content. In the internal circulation non-hygroscopic path, the internal circulation airflow 20 passes through the internal circulation air intake damper 121, the air conditioning filter 300 and the blower 400 in sequence. In this path, the internal circulation airflow 20 is not adsorbed by the adsorption device 200, but directly enters the air conditioning filter 300. The openings of the internal circulation air intake damper 121 and the moisture absorption channel damper 122 can be adjusted, that is, the air volume of the internal circulation airflow 20 entering the ventilation channel from the internal circulation moisture absorption air intake path, and the air volume of the internal circulation airflow 20 entering the ventilation channel from the internal circulation non-hygroscopic air intake path can be adjusted. By comprehensively adjusting the openings of the internal circulation air intake damper 121 and the moisture absorption channel damper 122, it is possible to control whether the internal circulation airflow 20 passes through the adsorption device 200, and control the proportion of the internal circulation airflow 20 flowing through the adsorption device 200 in the total internal circulation airflow 20, with high controllability, flexible adjustment and changeability.

[0040] For example, the opening of the internal circulation air intake damper 121 and the moisture absorption channel damper 122 can be adjusted according to the season and the operating state of the air conditioning system (cooling or heating), so as to set the proportion of the internal circulation air flow 20 flowing through the adsorption device 200 in the total internal circulation air flow 20 in different seasons and usage scenarios by controlling the opening of the internal circulation air intake damper 121 and the moisture absorption channel damper 122. For example, when the external temperature of the cabin is higher than 10°C, the moisture absorption channel damper 122 is closed, the internal circulation air intake damper 121 is opened, and the internal circulation air flow 20 does not pass through the adsorption device 200. At this time, CO in the total internal circulation air flow 20 entering the ventilation channel is 1.3%. 2When the temperature outside the cabin is lower than 10°C, the moisture absorption channel damper 122 and the internal circulation air intake damper 121 are opened, and part of the internal circulation air flow 20 passes through the adsorption device 200. At this time, the total internal circulation air flow 20 entering the ventilation channel contains CO 2 and water content is reduced. Of course, in some cases where the temperature is lower (for example, the temperature is less than 0°C), the opening of the internal circulation air intake damper 121 can be further reduced, and the opening of the moisture absorption channel damper 122 can be further increased, so that the internal circulation airflow 20 flowing through the adsorption device 200 is circulated at a higher proportion in the total internal circulation airflow 20 to achieve energy saving. In addition, the actual vehicle driving condition or use condition can also be calibrated to evaluate the maximum proportion of the internal circulation airflow 20 flowing through the adsorption device 200 in the total internal circulation airflow 20 according to the actual road conditions, and the opening of the internal circulation air intake damper 121 and the moisture absorption channel damper 122 at this time is used as the setting value, so as to save energy as much as possible.

[0041] Furthermore, in this embodiment, an external circulation air intake damper 111 is provided at the external circulation air inlet 110, and the opening of the external circulation air intake damper 111 is adjustable. By adjusting the opening of the external circulation air intake damper 111, the air volume of the external circulation airflow 10 entering the ventilation channel from the external circulation air intake path can be controlled. Therefore, by comprehensively adjusting the openings of the external circulation air intake damper 111, the internal circulation air intake damper 121 and the moisture absorption channel damper 122, the proportion of the total internal circulation airflow 20 in the total intake air can be controlled, and the proportion of the internal circulation airflow 20 flowing through the adsorption device 200 in the total internal circulation airflow 20 can also be adjusted, so that the regulation of the air inlet box of the air conditioner is more accurate and flexible, and the openings of the external circulation air intake damper 111, the internal circulation air intake damper 121 and the moisture absorption channel damper 122 can be adjusted according to the operating state of the air conditioning system. For example, when the cabin temperature is lower than 10°C, the opening of the external circulation air intake damper 111 can be appropriately reduced, and the opening of the moisture absorption channel damper 122 or the internal circulation air intake damper 121 can be increased to increase the proportion of the total internal circulation air intake in the total air intake, so that more heat of the internal circulation airflow 20 can be used to achieve energy saving. It should be noted that the opening of the moisture absorption channel damper 122 and the internal circulation air intake damper 121 can be adjusted according to the humidity and CO in the cabin. 2 When the humidity and CO2 concentration in the cabin are high, the opening of the moisture absorption channel damper 122 can be appropriately increased, and the opening of the internal circulation air intake damper 121 can be reduced, so as to ensure that the air intake volume of the total internal circulation airflow 20 is constant and the proportion of the total internal circulation airflow 20 in the total air intake remains unchanged. Of course, in some usage conditions, the openings of the moisture absorption channel damper 122 and the internal circulation air intake damper 121 can also be increased at the same time. At this time, the air intake volume of the total internal circulation airflow 20 increases, and the proportion of the total internal circulation airflow 20 in the total air intake increases.

[0042] See also Figure 2 The adsorption device 200 in this embodiment includes a mounting frame 210 and an adsorption core 220. The adsorption core 220 can adsorb CO 2 and water, the adsorption core 220 is arranged on the mounting frame 210, and the mounting frame 210 is connected to the box body 100. For example, in this embodiment, the mounting frame 210 can be fixed to the box body 100 by means of clamping, bonding, etc. The adsorption core 220 includes a carrier 221 and an adsorbent 222. The carrier 221 is in a grid or grid shape to allow the internal circulation airflow 20 to pass through, and the carrier 221 can carry or fix the adsorbent 222. For example, the adsorbent 222 can use one or more of granular activated carbon, zeolite or molecular sieve as a matrix material to absorb CO 2 The adsorbent 222 is evenly distributed on the carrier 221, thereby adsorbing CO in the internal circulating airflow 20 entering the lower ventilation space. 2 Effectively adsorbs water to control CO in the cabin 2 The concentration and humidity are within the optimal range, which will not cause fogging of the windows and drowsiness of the passengers in the vehicle. Of course, in other embodiments, the adsorbent 222 can also be selected from a device with ventilation, CO adsorption, etc. 2 and a plate with the ability to absorb water, the carrier 221 can be omitted.

[0043] Furthermore, the adsorption device 200 also includes a heater 230, and the heater 230 is connected to the mounting frame 210. The heater 230 can be a PTC heater, and the PTC heater includes a plurality of heating wires, and the plurality of heating wires are staggered and distributed in a grid shape. As an optional scheme, the heater 230 can be set as one, and the heater 230 is set on one side of the adsorption core 220, and the adsorption core 220 and the heater 230 are fixed by the mounting frame 210. When the water adsorbed by the adsorbent 222 reaches a certain proportion, the adsorbent 222 can be heated by the heater 230 to evaporate the water in the adsorbent 222 and discharge it out of the ventilation space through the drain or the air outlet 130. Of course, the heat generated by the heater 230 can also be used to heat the internal circulation airflow 20 in the lower ventilation space 140, thereby further reducing energy consumption and effectively utilizing waste heat. In addition, it should be noted that the heater 230 is generally in a state where the vehicle is parked when in use. Of course, in other embodiments, the number of heaters 230 may also be two, and the two heaters 230 are respectively disposed on both sides of the adsorption core 220 , and the adsorption core 220 and the two heaters 230 are fixed by the mounting frame 210 .

[0044] See also Figure 3In some embodiments, two adsorption cores 220 may be provided, and one heater 230 may be provided. In this case, the heater 230 is sandwiched between the two adsorption cores 220. The two adsorption cores 220 are provided with one side of the adsorbent 222 close to the heater 230, so that the heater 230 can heat the adsorbent 222. The carriers 221 of the two adsorption cores 220 are located at the outermost side. That is, the carrier 221, the adsorbent 222, the heater 230, the adsorbent 222 and the carrier 221 are stacked in sequence, and the two adsorption cores 220 and the heater 230 are fixed by the mounting frame 210. Of course, in other embodiments, the number of adsorption cores 220, the number of heaters 230, and the arrangement thereof can be flexibly adjusted. However, it should be noted that the adsorption cores 220 will cause a pressure drop in the internal circulation airflow 20, so the number of adsorption cores 220 should not be set too much.

[0045] This embodiment provides an air conditioning system, including the above-mentioned air conditioning air inlet box, and the air outlet 130 of the air conditioning air inlet box is connected to the inlet of the air conditioning distribution box. By adopting the air conditioning air inlet box in this embodiment, the proportion of the external circulation airflow 10 introduced into the air conditioning air inlet box in the total air intake can be relatively reduced, and the proportion of the internal circulation airflow 20 introduced into the air conditioning air inlet box in the total air intake can be increased, thereby effectively utilizing the heat in the internal circulation airflow 20 and reducing energy consumption. At the same time, since the adsorption device 200 in the air conditioning air inlet box can absorb CO in the internal circulation airflow 20 2 and water, thereby reducing the CO in the mixed air flow 30 entering the air conditioning distribution box 2 The air flow from the air conditioning distribution box to each position in the cabin has low humidity, the windows are not easy to fog, and the CO 2 The concentration is low and is less likely to cause drowsiness for drivers or passengers, thus improving safety.

[0046] This embodiment also provides a vehicle, including a vehicle body and the above-mentioned air conditioning system, wherein the air conditioning system is arranged on the vehicle body. A relatively closed cabin is formed inside the vehicle body, and the outlet of the air conditioning system is arranged on the vehicle body, and can supply cold air or hot air into the cabin. When the air conditioning system in this embodiment is used, energy consumption can be reduced, so that more electric energy can be used to drive the vehicle, which helps to improve the vehicle's cruising range, while ensuring that the windows do not fog up, the driver and passengers do not feel sleepy, and avoid fogging risks and health risks.

[0047] Embodiment 2

[0048] The present embodiment also uses a single-layer air conditioning air inlet box as an example for explanation. The difference between the present embodiment and the present embodiment is that the adsorption device 200 and the internal circulation air intake damper 121 at the internal circulation air inlet 120 are arranged differently in the present embodiment.

[0049] like Figure 4As shown, this embodiment provides an air-conditioning air inlet box, which also includes a box body 100, an adsorption device 200, an air-conditioning filter element 300 and a blower 400. The air-conditioning air inlet box also includes two air inlet paths. One is an external circulation air inlet path, in which the external circulation airflow 10 enters the ventilation channel from the external circulation air inlet 110, and then flows through the air-conditioning filter element 300 and the blower 400 in sequence before being sent out from the air outlet 130. The second is an internal circulation air inlet path, in which the internal circulation airflow 20 enters the adsorption device 200 from the internal circulation air inlet 120, and after passing through the adsorption device 200, it flows through the air-conditioning filter element 300 and the blower 400 in sequence before being sent out from the air outlet 130.

[0050] In this embodiment, the size of the adsorption device 200 is relatively large, and only the internal circulation air intake damper 121 is provided at the internal circulation air inlet 120. The adsorption device 200 is arranged downstream of the internal circulation air intake damper 121, and can completely cover the flow surface of the internal circulation airflow 20. That is, there is only one internal circulation air intake path, which is the internal circulation moisture absorption air intake path. In this internal circulation moisture absorption path, the internal circulation airflow 20 passes through the internal circulation air intake damper 121, the adsorption device 200, the air conditioning filter element 300 and the blower 400 in sequence. In this path, the adsorption device 200 can absorb CO in the internal circulation airflow 20. 2 and water to reduce the CO in the internal circulating gas stream 20. 2 content, water content. However, it should be noted that in this internal circulation moisture absorption path, all internal circulation airflows 20 must pass through the internal circulation air intake damper 121, the adsorption device 200, the air conditioning filter 300 and the blower 400 in sequence, that is to say, the proportion of the internal circulation airflow 20 flowing through the adsorption device 200 in the total internal circulation airflow 20 is not adjustable, and the proportion of the internal circulation airflow 20 flowing through the adsorption device 200 in the total internal circulation airflow 20 is 1. Compared with the solution of arranging two dampers (internal circulation air intake damper 121 and moisture absorption channel damper 122) in Example 1, the air intake adjustment of the air conditioning air inlet box in this embodiment is not as flexible as the air conditioning air inlet box in Example 1, and the pressure drop is slightly higher, but the advantages of the air conditioning air inlet box in this embodiment are: cost reduction, dehumidification, CO removal 2 The effect is higher than that of the air-conditioning air inlet box in the first embodiment.

[0051] Furthermore, in this embodiment, an external circulation air intake damper 111 is provided at the external circulation air inlet 110, and the opening of the external circulation air intake damper 111 is adjustable. By adjusting the opening of the external circulation air intake damper 111, the air volume of the external circulation airflow 10 entering the ventilation channel from the external circulation air intake path can be controlled. The internal circulation airflow 20 entering the ventilation channel through the internal circulation moisture absorption path and the external circulation airflow 10 entering the ventilation channel through the external circulation air intake path are mixed into a mixed airflow 30 at the air conditioning filter element 300, and then driven by the blower 400 to enter the air conditioning distribution box. Therefore, by comprehensively adjusting the opening of the external circulation air intake damper 111 and the internal circulation air intake damper 121, the proportion of the internal circulation airflow 20 in the total air intake can be controlled, and the air intake control of the air conditioning air intake box is accurate and flexible, and the opening of the external circulation air intake damper 111 and the internal circulation air intake damper 121 can be adjusted according to the operating state of the air conditioning system. For example, when the temperature outside the cabin is lower than 10°C, the opening of the external circulation air intake damper 111 can be appropriately reduced, and the opening of the internal circulation air intake damper 121 can be increased to increase the proportion of the internal circulation air intake in the total air intake, thereby being able to utilize more heat from the internal circulation airflow 20, thereby achieving greater energy saving.

[0052] This embodiment provides an air conditioning system, including the above-mentioned air conditioning air inlet box, and the air outlet 130 of the air conditioning air inlet box is connected to the inlet of the air conditioning distribution box. By adopting the air conditioning air inlet box in this embodiment, the proportion of the external circulation airflow 10 introduced into the air conditioning air inlet box in the total air intake can be relatively reduced, and the proportion of the internal circulation airflow 20 introduced into the air conditioning air inlet box in the total air intake can be increased, thereby effectively utilizing the heat in the internal circulation airflow 20 and reducing energy consumption. At the same time, since the adsorption device 200 in the air conditioning air inlet box can absorb CO in the internal circulation airflow 20 2 and water, thereby reducing the CO in the mixed air flow 30 entering the air conditioning distribution box 2 The air flow from the air conditioning distribution box to each position in the cabin has low humidity, the windows are not easy to fog, and the CO 2 The concentration is low and is less likely to cause drowsiness for drivers or passengers, thus improving safety.

[0053] This embodiment also provides a vehicle, including a vehicle body and the above-mentioned air conditioning system, wherein the air conditioning system is arranged on the vehicle body. A relatively closed cabin is formed inside the vehicle body, and the outlet of the air conditioning system is arranged on the vehicle body, and can supply cold air or hot air into the cabin. When the air conditioning system in this embodiment is used, energy consumption can be reduced, so that more electric energy can be used to drive the vehicle, which helps to improve the vehicle's cruising range, while ensuring that the windows do not fog up, the driver and passengers do not feel sleepy, and avoid fogging risks and health risks.

[0054] The remaining structures in this embodiment are the same as those in the first embodiment and will not be described in detail here.

[0055] Embodiment 3

[0056] In this embodiment, a double-layer air-conditioning air inlet box is used as an example for explanation. The difference between the air-conditioning air inlet box in this embodiment and the air-conditioning air inlet box in the first embodiment is that a partition rib is provided inside the box body 100 of the air-conditioning air inlet box in this embodiment, and the ventilation channel is divided into a first channel and a second channel by the partition rib, wherein the first channel is connected to the external circulation air inlet 110, and the second channel is connected to the internal circulation air inlet 120, and an adsorption device 200 is provided at the internal circulation air inlet 120. For example, in this embodiment, the first channel and the second channel can share the same air-conditioning filter element 300 and the same blower 400, which reduces costs and has a more compact structure.

[0057] In this embodiment, the air inlet box of the air conditioner also includes two air inlet paths. One is the external circulation air inlet path, where the external circulation airflow 10 enters the first channel from the external circulation air inlet 110, then flows through the air conditioner filter 300 and the blower 400 in sequence, and is then sent out from the air outlet 130. The other is the internal circulation air inlet path, where the internal circulation airflow 20 enters the second channel through the internal circulation air inlet 120 and the adsorption device 200, and is dehumidified and deCO2-free by the adsorption device 200. 2 The air then flows through the air conditioning filter 300 and the blower 400 in sequence and is then sent out from the air outlet 130. By adopting the design of separating the first channel and the second channel and introducing the low-temperature and low-humidity external circulation airflow 10 outside the cabin into the first channel, the CO in the cabin can be reduced. 2 content, avoid CO 2 A high concentration may cause the driver to feel sleepy. An internal circulation airflow 20 with a high temperature and humidity is introduced into the second channel, and the CO in the internal circulation airflow 20 is reduced by the adsorption device 200. 2 content and water content to ensure that the windows do not fog and CO 2 When the concentration is low, the heating energy consumption of the air conditioning system is reduced.

[0058] Of course, in other embodiments, the first channel and the second channel may be separately configured with corresponding air conditioning filter element 300 and blower 400 respectively.

[0059] Furthermore, in this embodiment, the moisture absorption channel damper 122 and the internal circulation air intake damper 121 are provided at the internal circulation air inlet 120, and the adsorption device 200 is arranged downstream of the moisture absorption channel damper 122. The openings of the internal circulation air intake damper 121 and the moisture absorption channel damper 122 can be adjusted, that is, the air volume of the internal circulation airflow 20 entering the ventilation channel from the internal circulation moisture absorption air intake path, and the air volume of the internal circulation airflow 20 entering the ventilation channel from the internal circulation non-moisture absorption air intake path can be adjusted. By comprehensively adjusting the openings of the internal circulation air intake damper 121 and the moisture absorption channel damper 122, it is possible to control whether the internal circulation airflow 20 passes through the adsorption device 200, and to control the proportion of the internal circulation airflow 20 flowing through the adsorption device 200 in the total internal circulation airflow 20, with high controllability, flexible and changeable adjustment. An external circulation air intake damper 111 is provided at the external circulation air inlet 110, and the opening of the external circulation air intake damper 111 is adjustable. The air volume of the external circulation airflow 10 entering the ventilation channel from the external circulation air intake path can be controlled by adjusting the opening of the external circulation air intake damper 111. The total internal circulation airflow 20 entering the second channel through the internal circulation moisture absorption path is driven by the blower 400 to enter the first ventilation space of the air conditioning distribution box after being filtered by the air conditioning filter element 300. At the same time, the external circulation airflow 10 entering the first channel through the external circulation air intake path is driven by the blower 400 to enter the second ventilation space of the air conditioning distribution box after being filtered by the air conditioning filter element 300. After that, the air conditioning distribution box distributes the external circulation airflow 10 and the internal circulation airflow 20 to various positions in the vehicle cabin. Therefore, by comprehensively adjusting the openings of the external circulation air intake damper 111, the internal circulation air intake damper 121 and the moisture absorption channel damper 122, the proportion of the internal circulation airflow 20 flowing through the adsorption device 200 in the total internal circulation airflow 20 and the proportion of the total internal circulation airflow 20 in the total intake air can be adjusted, so that the control of the air intake box of the air conditioner is more accurate and flexible, so as to meet the temperature, humidity and CO in the vehicle cabin. 2 When the content is required, the heat in the internal circulating airflow 20 can be utilized as much as possible, thereby achieving a greater degree of energy saving.

[0060] Of course, in some embodiments, only one internal circulation air inlet path may be provided. An internal circulation air inlet damper 121 is provided at the internal circulation air inlet 120, and the adsorption device 200 is arranged downstream of the internal circulation air inlet damper 121 and can completely cover the flow surface of the internal circulation airflow 20. The advantages of the air inlet box of the air conditioner in this embodiment are: cost reduction, dehumidification, CO removal 2 The effect is high.

[0061] This embodiment provides an air conditioning system, including the above-mentioned air conditioning air inlet box, and the air outlet 130 of the air conditioning air inlet box is connected to the inlet of the air conditioning distribution box. Specifically, the air conditioning distribution box includes a first ventilation space and a second ventilation space, and the air outlet 130 of the first channel of the air conditioning air inlet box is connected to the inlet of the first ventilation space of the air conditioning distribution box. The air outlet 130 of the second channel of the air conditioning air inlet box is connected to the inlet of the second ventilation space of the air conditioning distribution box.

[0062] By adopting the air-conditioning air inlet box of this embodiment, the proportion of the external circulation airflow 10 introduced into the air-conditioning air inlet box in the total air intake can be relatively reduced, and the proportion of the internal circulation airflow 20 introduced into the air-conditioning air inlet box in the total air intake can be increased, thereby effectively utilizing the heat in the internal circulation airflow 20 and reducing energy consumption. At the same time, since the adsorption device 200 in the air-conditioning air inlet box can absorb CO in the internal circulation airflow 20, 2 and water, thereby reducing the CO in the mixed air flow 30 entering the air conditioning distribution box 2 The air flow from the air conditioning distribution box to each position in the cabin has low humidity, the windows are not easy to fog, and the CO 2 The concentration is low, which is not likely to cause drowsiness to the driver or passengers, and safety is improved. In addition, since the air-conditioning air inlet box adopts this partition design, the energy-saving effect of the air-conditioning system is more obvious, and more internal circulation airflow 20 can be introduced into the second channel of the air-conditioning air inlet box. When the internal circulation ratio is high, the windows in the cabin are guaranteed to be fogged, and the driver and passengers are not drowsy, which has a significant effect on reducing energy consumption.

[0063] This embodiment also provides a vehicle, including a vehicle body and the above-mentioned air conditioning system, wherein the air conditioning system is arranged on the vehicle body. A relatively closed cabin is formed inside the vehicle body, and the outlet of the air conditioning system is arranged on the vehicle body, and can supply cold air or hot air into the cabin. When the air conditioning system in this embodiment is used, energy consumption can be reduced, so that more electric energy can be used to drive the vehicle, which helps to improve the vehicle's cruising range, while ensuring that the windows do not fog up, the driver and passengers do not feel sleepy, and avoid fogging risks and health risks.

[0064] The remaining structures in this embodiment are the same as those in the first embodiment and will not be described in detail here.
