Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, and in particular to an air conditioning distribution 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 requires the air conditioning system to consume electricity to heat it before entering 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, it is still necessary to ensure the entry of fresh air to a large extent when the air conditioning system is intake, and reduce the risk of fogging and health risks by sacrificing energy consumption.

[0040] 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.

[0041] Embodiment 1

[0042] This embodiment provides an air conditioning distribution box, see Figure 1 and Figure 2 In this embodiment, a double-layer air conditioning system is used as an example. The air conditioning distribution box includes a box body 100, an evaporator 200, an adsorption device 300 and a heating device 400. The box body 100 is provided with an air inlet 110 and an air outlet. The interior of the box body 100 is hollow to form a ventilation space. The ventilation space is connected to the air inlet 110 and the air outlet. The external circulation airflow 10 and the internal circulation airflow 20 flow through the air inlet 110, the ventilation space and the air outlet in sequence. A partition plate 190 is provided in the box body 100. The partition plate 190 divides the air inlet 110 into an external circulation air inlet 111 and an internal circulation air inlet 112, and divides the ventilation space into an external circulation ventilation space 130 and an internal circulation ventilation space 140. The outer circulation air inlet 111 is connected to the outer circulation ventilation space 130, and the outer circulation airflow 10 flows through the outer circulation air inlet 111, the outer circulation ventilation space 130 and the air outlet in sequence; the inner circulation air inlet 112 is connected to the inner circulation ventilation space 140, and the inner circulation airflow 20 flows through the inner circulation air inlet 112, the inner circulation ventilation space 140 and the air outlet in sequence. The adsorption device 300 is arranged in the inner circulation ventilation space 140.

[0043] The evaporator 200 and the heating device 400 are both installed on the housing 100 and penetrate the external circulation ventilation space 130 and the internal circulation ventilation space 140. The evaporator 200 is arranged at the air inlet 110 and covers the internal circulation air inlet 112 and the external circulation air inlet 111. The evaporator 200 exchanges heat with the external circulation airflow 10 and the internal circulation airflow 20, and cools down the external circulation airflow 10 and the internal circulation airflow 20 at the same time; the adsorption device 300 is arranged upstream and / or downstream of the evaporator 200, and the adsorption device 300 is arranged close to the internal circulation air inlet 112. When the external circulation airflow 10 and the internal circulation airflow 20 enter the internal circulation ventilation space 140 from the internal circulation air inlet 112, the adsorption device 300 can adsorb CO in the internal circulation airflow 20 before entering the evaporator 200 and / or after flowing through the evaporator 200. 2 and water, thereby reducing the CO in the internal circulating airflow 20 2 The heating device 400 is arranged downstream of the evaporator 200, and half of the heating device 400 is located in the outer circulation ventilation space 130, and the other half is located in the inner circulation ventilation space 140. The heating device 400 can also exchange heat with the outer circulation airflow 10 and the inner circulation airflow 20, and the outer circulation airflow 10 and the inner circulation airflow 20 are heated by the heating device 400.

[0044] When the air conditioning system is in heating mode, CO 2 The internal circulation airflow 20 after being mixed with water passes through the heating device 400 in the internal circulation ventilation space 140 and then flows out of the internal circulation ventilation space 140 from the air outlet, thereby reducing the humidity and CO of the internal circulation airflow 20 from the root. 2 Concentration. Since CO in the internal circulating airflow 20 2 The content of water in the air is reduced. At this time, the proportion of the internal circulation airflow 20 in the total air intake is appropriately increased, which is not easy to cause the windows in the cabin to fog up, and the passengers are not easy to feel sleepy. In addition, since the proportion of the internal circulation airflow 20 in the total air intake is increased and the temperature of the internal circulation airflow 20 is relatively high, the energy consumption of the heating device 400 for heating the external circulation airflow 10 and the internal circulation airflow 20 can be relatively reduced. When the air conditioning system is in cooling mode, the removal of CO 2 The internal circulation airflow 20 after being mixed with water flows directly out of the internal circulation ventilation space 140 from the air outlet. 2 The content is reduced, and the passengers in the cabin are not easily sleepy. In addition, because it is in cooling mode, the temperature in the cabin is low, so the windows in the cabin will not fog up. It should be noted that the adsorption device 300 in this embodiment mainly plays its role in the heating mode, which can well reduce the energy consumption of the air conditioning system in the heating mode in winter, so as to use more electric energy for vehicle endurance, which helps to increase the vehicle's mileage.

[0045] Continue to see Figure 1 and Figure 2 In this embodiment, two adsorption devices 300 are provided, and the two adsorption devices 300 are arranged upstream and downstream of the evaporator 200, respectively, and the two adsorption devices 300 are both located in the internal circulation ventilation space 140. By arranging the adsorption devices 300 upstream and downstream of the evaporator 200, CO in the internal circulation airflow 20 can be 2 Adsorbed twice with water to achieve better removal of CO 2 The ability to absorb water can better resist passenger fatigue and drowsiness, resist window fogging and save energy.

[0046] Of course, in other embodiments, only one adsorption device 300 may be provided, and the adsorption device 300 may be arranged upstream of the evaporator 200, and the adsorption device 300 adsorbs CO in the internal circulation airflow 20 in the internal circulation ventilation space 140. 2 After the internal circulation airflow 20 flows through the evaporator 200, the internal circulation airflow 20 flows through the evaporator 200. Alternatively, in some embodiments, only one adsorption device 300 may be provided, and the adsorption device 300 may be arranged downstream of the evaporator 200. The adsorption device 300 may adsorb CO in the internal circulation airflow 20 in the internal circulation ventilation space 140 after the internal circulation airflow 20 flows through the evaporator 200. 2 and water, and then the internal circulation airflow 20 flows out from the air outlet or enters the heating device 400 for heating. When one adsorption device 300 is used, the cost of the air conditioning distribution box is reduced. In addition, when the internal circulation airflow 20 flows through the adsorption device 300, it will cause a pressure drop of the internal circulation airflow 20. The pressure drop will be more obvious when two adsorption devices 300 are used. Using one adsorption device 300 can alleviate the effect of the adsorption device 300 on the pressure drop of the internal circulation airflow 20.

[0047] Continue to see Figure 1The housing 100 in this embodiment includes a bottom wall, and a drain port 150 communicating with the outside is provided on the bottom wall. The drain port 150 is located at the lowest point of the bottom wall. The water adsorbed by the adsorption device 300 can flow along the bottom wall to the drain port 150 after being collected and flow out from the drain port 150, so as to prevent the water from being evaporated again in the inner circulation ventilation space 140 for a long time, resulting in an increase in the humidity of the inner circulation airflow 20. In addition, the evaporator 200 in this embodiment can share the same drain port 150 with the adsorption device 300, and the water generated at the evaporator 200 can also be collected and flow along the bottom wall to the drain port 150 and flow out from the drain port 150. By utilizing the drainage structure of the evaporator 200, the adsorption device 300 and the evaporator 200 can both achieve the drainage function, thereby reducing the cost. For example, the bottom wall in this embodiment includes a first inclined wall 160 and a second inclined wall 170, and the drain port 150 is arranged at the connection of the first inclined wall 160 and the second inclined wall 170, and the connection of the first inclined wall 160 and the second inclined wall 170 is at the lowest position. The arrangement of the first inclined wall 160 and the second inclined wall 170 provides a certain guiding effect on the circulation of water. The shape and the inclination angle of the first inclined wall 160 and the second inclined wall 170 are not specifically limited in this embodiment, as long as the drain port 150 is at the lowest point. Further, a water passage 1601 is arranged between the evaporator 200 and the first inclined wall 160, and the water passage 1601 allows water to flow through, so that the water flowing out of the adsorption device 300 located upstream of the evaporator 200 can flow to the drain port 150 through the water passage 1601.

[0048] Optionally, in some embodiments, the adsorption device 300 located downstream of the evaporator 200 may also be tilted toward the side close to the drain outlet 150 so that an angle is formed between the adsorption device 300 and the axial direction of the drain outlet 150 , and water adsorbed by the adsorption device 300 flows more easily toward the drain outlet 150 .

[0049] Furthermore, one of the adsorption devices 300 in this embodiment is arranged downstream of the evaporator 200, the drain port 180 is located between the adsorption device 300 and the evaporator 200, and a water baffle 180 is provided between the adsorption device 300 and the heating device 400. The water baffle 180 is provided on the housing 100 and located in the internal circulation ventilation space 140, and the water baffle 180 is located downstream of the evaporator 200, the drain port 180 and the adsorption device 300. By providing the water baffle 180, it is possible to prevent water flowing out of the adsorption device 300 or the evaporator 200 from being carried to the air outlet or the heating device 400 by the internal circulation airflow 20, thereby further reducing the humidity of the internal circulation airflow 20 at the air outlet, and avoiding fogging of the vehicle windows as much as possible.

[0050] See also Figure 3 The adsorption device 300 in this embodiment includes a mounting frame 310 and an adsorption core 320. The adsorption core 320 can adsorb CO2 The adsorption core 320 is arranged on the mounting frame 310, and the mounting frame 310 is connected to the box body 100. For example, in this embodiment, the mounting frame 310 can be fixed to the box body 100 by means of clamping, bonding, etc. The adsorption core 320 includes a carrier 321 and an adsorbent 322. The carrier 321 is in a grid or grid shape to allow the internal circulation airflow 20 to pass through. The carrier 321 is used to carry or fix the adsorbent 322. The adsorbent 322 uses one or more of granular activated carbon, zeolite or molecular sieve as a matrix material to absorb CO 2 and water, thereby removing CO from the internal circulation airflow 20 entering the internal circulation ventilation space 140. 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 passengers in the vehicle. Of course, in other embodiments, the adsorbent 322 can also be selected from a material having ventilation, adsorption of CO 2 and a plate with the ability to absorb water, the carrier 321 can be omitted.

[0051] Furthermore, the adsorption device 300 also includes a heater 330, and the heater 330 is connected to the carrier 320. Exemplarily, the heater 330 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 330 can be set as one, and the heater 330 is set on one side of the adsorption core 320, and the adsorption core 320 and the heater 330 are fixed by the mounting frame 310. When the water adsorbed by the adsorbent 322 reaches a certain proportion, the adsorbent 322 can be heated by the heater 330 to evaporate the water in the adsorbent 322 and discharge it out of the ventilation space through the drain 150 or the air outlet. Of course, the heat generated by the heater 330 can also be used to heat the inner circulation airflow 20 in the inner circulation ventilation space 140, thereby further reducing energy consumption and effectively utilizing waste heat. In addition, it should be noted that the heater 330 is generally used when the vehicle is parked. Of course, in other embodiments, two heaters 330 may also be provided, and the two heaters 330 are respectively provided on both sides of the adsorption core 320 , and the adsorption core 320 and the two heaters 330 are fixed by the mounting frame 310 .

[0052] See also Figure 4In some embodiments, two adsorption cores 320 may be provided, and one heater 330 may be provided. In this case, the heater 330 is sandwiched between the two adsorption cores 320. The two adsorption cores 320 are provided with one side of the adsorbent 322 close to the heater 330, which is conducive to the heater 320 heating the adsorbent 322. The carriers 321 of the two adsorption cores 320 are located at the outermost side. That is, the carrier 321, the adsorbent 322, the heater 330, the adsorbent 322 and the carrier 321 are stacked in sequence, and the two adsorption cores 320 and the heater 330 are fixed by the mounting frame 310. Of course, in other embodiments, the number of adsorption cores 320, the number of heaters 330, and the arrangement thereof can be flexibly adjusted. However, it should be noted that the adsorption cores 320 will cause a pressure drop in the internal circulation airflow 20, so the number of adsorption cores 320 should not be set too much.

[0053] Continue to see Figure 1 In this embodiment, the outer circulation ventilation space 130 is provided with an outer circulation cold end temperature damper 131 and an outer circulation hot end temperature damper 132, both of which are mounted on the box body 100, and the outer circulation hot end temperature damper 132 is located upstream of the heating device 400. The inner circulation ventilation space 140 is provided with an inner circulation cold end temperature damper 141 and an inner circulation hot end temperature damper 142, both of which are mounted on the box body 100, and the inner circulation hot end temperature damper 142 is located upstream of the heating device 400. The outer circulation ventilation space 130 is connected to the inner circulation ventilation space 140, and when the outer circulation cold end temperature damper 131 and the outer circulation hot end temperature damper 132 are in different positions, the direction of the outer circulation airflow 10 in the outer circulation ventilation space 130 will change. Furthermore, when the internal circulation cold end temperature damper 141 and the internal circulation hot end temperature damper 142 are in different working positions, the direction of the internal circulation airflow 20 in the internal circulation ventilation space 140 will also change, and part of the external circulation airflow 10 may enter the internal circulation ventilation space 140, and part of the internal circulation airflow 20 may also enter the external circulation ventilation space 130. That is to say, the airflow flowing out of the air outlet includes the internal circulation airflow 20 and the external circulation airflow 10. For the convenience of explanation, the airflow flowing out of the air outlet is collectively referred to as the airflow.

[0054] When the air conditioning system is in heating mode, the external circulation cold end temperature damper 131 and the internal circulation cold end temperature damper 141 are closed, and the external circulation hot end temperature damper 132 and the internal circulation hot end temperature damper 142 are opened. The external circulation airflow 10 passes through the external circulation air inlet 111, the evaporator 200, the external circulation hot end temperature damper 132 and the heating device 400 in sequence, and then flows out of the external circulation ventilation space 130 from the air outlet. Among them, the opening degree of the external circulation hot end temperature damper 132 can be adjusted to adjust the air volume of the external circulation airflow 10 entering the heating device 400. The internal circulation hot end temperature damper 142 and the internal circulation cold end temperature damper 141 have the same principle as the external circulation hot end temperature damper 132 and the external circulation cold end temperature damper 131 for controlling hot and cold air. The internal circulation airflow 20 passes through the internal circulation air inlet 112, the adsorption device 300, the evaporator 200, the adsorption device 300, the internal circulation hot end temperature damper 142 and the heating device 400 in sequence, and then flows out of the internal circulation ventilation space 140 from the air outlet. Among them, the opening of the internal circulation hot end temperature damper 142 can be adjusted to adjust the air volume of the internal circulation airflow 20 entering the heating device 400. The heating device 400 can exchange heat with the external circulation airflow 10 and the internal circulation airflow 20 to achieve the purpose of heating. By comprehensively adjusting the opening of the external circulation hot end temperature damper 132 and the internal circulation hot end temperature damper 142, the proportion of the internal circulation airflow 20 in the total air volume can be controlled as a whole, thereby regulating the air outlet temperature. Of course, the air outlet temperature is also related to the heating power of the heating device 400. When the heating power of the heater 400 increases, the outlet air temperature of the air outlet also increases; when the heating power of the heater 400 decreases, the outlet air temperature of the air outlet also decreases; when the heating power of the heater 400 remains unchanged, the opening of the internal circulation hot end temperature damper 142 is increased, so that the proportion of the internal circulation airflow 20 in the total air output is increased, and the outlet air temperature will be higher than when the internal circulation airflow 20 is smaller in the total air output, thereby helping to reduce the energy consumption of the heater 400.

[0055] See also Figure 2When the air conditioning system is in cooling mode, the external circulation cold end temperature damper 131 and the internal circulation cold end temperature damper 141 are opened, and the external circulation hot end temperature damper 132 and the internal circulation hot end temperature damper 142 are closed. After the external circulation airflow 10 passes through the external circulation air inlet 111, the evaporator 200 and the external circulation cold end temperature damper 131 in sequence, it flows out of the external circulation ventilation space 130 from the air outlet. Among them, the opening degree of the external circulation cold end temperature damper 131 can be adjusted to adjust the air volume of the external circulation airflow 10 entering the air outlet. After the internal circulation airflow 20 passes through the internal circulation air inlet 112, the evaporator 200 and the internal circulation cold end temperature damper 141 in sequence, it flows out of the internal circulation ventilation space 140 from the air outlet. Among them, the opening degree of the internal circulation cold end temperature damper 141 can be adjusted to adjust the air volume of the internal circulation airflow 20 entering the air outlet. By adjusting the refrigeration power of the evaporator 200, the air outlet temperature of the air outlet can be adjusted. The evaporator 200 can exchange heat with the external circulation airflow 10 and the internal circulation airflow 20 to achieve the purpose of refrigeration. When the refrigeration power of the evaporator 200 increases, the outlet air temperature of the air outlet decreases; when the refrigeration power of the evaporator 200 decreases, the outlet air temperature of the air outlet increases; when the refrigeration power of the evaporator 200 remains unchanged, the opening of the internal circulation cold end temperature damper 141 is increased, so that the proportion of the internal circulation airflow 20 in the total air output increases, and the air output temperature will be lower than when the internal circulation airflow 20 is smaller in the total air output, because the temperature of the outside space is higher than the temperature in the cabin in summer, that is, the temperature of the external circulation airflow 10 is higher than the temperature of the internal circulation airflow 20. Therefore, when the proportion of the internal circulation airflow 20 in the total air output is high, the temperature in the cabin is relatively low, which helps to reduce the energy consumption of the evaporator 200.

[0056] Continue to see Figure 1 and Figure 2 The air outlets in this embodiment include a defrost air outlet 121, a front face air outlet 122, a front foot air outlet 123, a rear face air outlet 124 and a rear foot air outlet 125. The defrost air outlet 121, the front face air outlet 122, the front foot air outlet 123, the rear face air outlet 124 and the rear foot air outlet 125 are respectively arranged at various locations of the vehicle body, and hot air or cold air is delivered to various locations in the vehicle cabin through the above-mentioned air outlets. For example, the defrost air outlet 121 is arranged in the front row of the vehicle body and close to the window. The air flow blown out by the defrost air outlet 121 can flow to the window to avoid fogging; the front face air outlet 122 and the front foot air outlet 123 are arranged in the front row of the vehicle body, the front face air outlet 122 is aimed at the face of the driver or the passenger, and the front foot air outlet 123 is aimed at the feet of the driver or the passenger; the rear face air outlet 124 and the rear foot air outlet 125 are arranged in the rear row of the vehicle body, the rear face air outlet 124 is aimed at the face of the passenger, and the rear foot air outlet 125 is aimed at the feet of the passenger.

[0057] Furthermore, a defrost damper 1211 is provided at the defrost air outlet 121, a front face damper 1221 is provided at the front face air outlet 122, a front foot damper 1231 is provided at the front foot air outlet 123, a rear face damper 1241 is provided at the rear face air outlet 124, and a rear foot damper 1251 is provided at the rear foot air outlet 125. The openings of the defrost damper 1211, the front face damper 1221, the front foot damper 1231, the rear face damper 1241 and the rear foot damper 1251 are all adjustable. By adjusting the openings of the defrost damper 1211, the front face damper 1221, the front foot damper 1231, the rear face damper 1241 and the rear foot damper 1251, the air volumes of the defrost air outlet 121, the front face air outlet 122, the front foot air outlet 123, the rear face air outlet 124 and the rear foot air outlet 125 can be adjusted respectively to meet different cooling and heating needs. It should be noted that when the air conditioning system is in heating mode, the air flow out of the defrost air outlet 121, the front air outlet 122, the front foot air outlet 123, the rear air outlet 124 and the rear foot air outlet 125 is the external circulation air flow 10 passing through the external circulation hot end temperature damper 132 and the heating device 400, or the internal circulation air flow 20 passing through the internal circulation hot end temperature damper 142 and the heating device 400. The air flow is heated by the heating device 400 and the air is discharged. They are all hot air; when the air-conditioning system is in cooling mode, the air flow out of the defrost air outlet 121, the front blowing face air outlet 122, the front blowing foot air outlet 123, the rear blowing face air outlet 124 and the rear blowing foot air outlet 125 is the external circulation air flow 10 passing through the evaporator 200 and the external circulation cold end temperature damper 131, or the internal circulation air flow 20 passing through the evaporator 200 and the internal circulation cold end temperature damper 141. The air flow passes through the evaporator 200 for cooling, and the air out is all cold air.

[0058] The present embodiment provides an air conditioning system, including an air conditioning air inlet box and the above-mentioned air conditioning distribution box. The air conditioning air inlet box is a double-layer air conditioning air inlet box, and the air conditioning air inlet box includes an external circulation ventilation channel and an internal circulation ventilation channel. The external circulation ventilation channel includes a first inlet and a first outlet, and the internal circulation ventilation channel includes a second inlet and a second outlet. The first outlet is connected to the external circulation air inlet 111 of the air conditioning distribution box, and the second outlet is connected to the internal circulation air inlet 112 of the air conditioning distribution box. The external circulation airflow 10 flows into the external circulation ventilation channel through the first inlet of the air conditioning air inlet box, then enters the external circulation ventilation space 130 of the air conditioning distribution box through the first outlet, and finally is discharged from the air outlet; the internal circulation airflow 20 flows into the internal circulation ventilation channel through the second inlet of the air conditioning air inlet box, then enters the internal circulation ventilation space 140 of the air conditioning distribution box through the second outlet, and finally is discharged from the air outlet.

[0059] By arranging the adsorption device 300 in the inner circulation ventilation space 140 of the double laminar flow air conditioning system, the adsorption device 300 can specifically adsorb the CO in the inner circulation airflow 20 in the inner circulation path. 2 The water is effectively adsorbed, which greatly reduces the CO 2 and water content, thereby avoiding fogging of the car windows and causing drowsiness in the driver and passengers. At the same time, because the proportion of the internal circulation airflow 20 in the total air intake can be appropriately increased, the heat in the internal circulation airflow 20 can be fully utilized, which plays a good energy-saving role.

[0060] In addition, the double-layer flow air-conditioning system itself also has a certain energy-saving effect. Coupled with the setting of the above-mentioned adsorption device 300, when heating is needed in winter, more internal circulation airflow 20 is introduced into the internal circulation ventilation space 140 of the air-conditioning distribution box, thereby reducing energy consumption to a minimum, and the energy-saving effect is obvious.

[0061] 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 air 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.

[0062] Embodiment 2

[0063] This embodiment provides an air conditioning distribution box, which is different from the air conditioning distribution box in the first embodiment in that the air conditioning distribution box in this embodiment is an air conditioning distribution box in a common single-layer air conditioning system.

[0064] Specifically, the air conditioning distribution box in this embodiment includes a box body 100, an evaporator 200, an adsorption device 300 and a heating device 400. The box body 100 is provided with only one air inlet 110 and multiple air outlets. The air inlet 110 can simultaneously allow the external circulation airflow 10 and the internal circulation airflow 20 to pass through. The multiple air outlets are arranged at various positions on the vehicle body. The box body 100 is hollow inside to form a ventilation space, which is connected to the air inlet 110 and the multiple air outlets. The external circulation airflow 10 and the internal circulation airflow 20 flow through the air inlet 110, the ventilation space and the air outlets in sequence.

[0065] The evaporator 200, the adsorption device 300 and the heating device 400 are all installed on the housing 100 and are located in the ventilation space. The evaporator 200 is arranged at the air inlet 110 and covers the air inlet 110. The evaporator 200 exchanges heat with the external circulation airflow 10 and the internal circulation airflow 20, and cools the external circulation airflow 10 and the internal circulation airflow 20 at the same time; the adsorption device 300 is arranged adjacent to the evaporator 200, and the adsorption device 300 can be arranged upstream and / or downstream of the evaporator 200, so that when the external circulation airflow 10 and the internal circulation airflow 20 enter the ventilation space from the air inlet 110, the adsorption device 300 can adsorb CO2 and water in the internal circulation airflow 20 before entering the evaporator 200 and / or after flowing through the evaporator 200, thereby reducing the CO2 content and humidity in the internal circulation airflow 20. The heating device 400 is arranged downstream of the evaporator 200 and the adsorption device 300 , and can also exchange heat with the external circulation airflow 10 and the internal circulation airflow 20 , and heat the external circulation airflow 10 and the internal circulation airflow 20 through the heating device 400 .

[0066] For example, this embodiment is described by taking the adsorption device 300 disposed both upstream and downstream of the evaporator 200 as an example, and the adsorption device 300 disposed downstream of the evaporator 200 is located upstream of the warm air device 400. The adsorption effect of CO2 and water in the internal circulation airflow 20 is improved by disposing two adsorption devices 300. Of course, in other embodiments, the adsorption device 300 may be disposed only upstream or downstream of the evaporator 200.

[0067] When the air conditioning system is in the heating mode, the inner circulation airflow 20 after removing CO2 and water and the outer circulation airflow 10 flow out of the ventilation space from the air outlet after passing through the heating device 400, which fundamentally reduces the humidity and CO2 concentration of the inner circulation airflow 20. Since the content of CO2 and water in the inner circulation airflow 20 is reduced, the proportion of the inner circulation airflow 20 in the total air intake is appropriately increased at this time, which is not easy to cause the windows in the cabin to fog up, and the passengers are not easy to get sleepy. In addition, since the proportion of the inner circulation airflow 20 in the total air intake is increased, and the temperature of the inner circulation airflow 20 is relatively high, the energy consumption of the heating device 400 when heating the outer circulation airflow 10 and the inner circulation airflow 20 can be relatively reduced. When the air conditioning system is in the cooling mode, the inner circulation airflow 20 after removing CO2 and water and the outer circulation airflow 10 flow directly out of the ventilation space from the air outlet. Since the content of CO2 in the inner circulation airflow 20 is reduced, the passengers in the cabin are not easy to get sleepy, and because it is in the cooling mode, the temperature in the cabin is low, so the windows in the cabin will not fog up at this time. It should be noted that, in this embodiment, the adsorption device 300 mainly plays its role in the heating mode, which can effectively reduce the energy consumption of the air-conditioning system in the heating mode in winter, so as to use more electric energy for vehicle endurance, which helps to improve the vehicle's mileage.

[0068] In addition, since the partition plate 190 is not required in the box 100 in this embodiment, a cold end temperature damper and a hot end temperature damper are provided in the ventilation space in this embodiment, and both the cold end temperature damper and the hot end temperature damper are installed on the box 100, and the hot end temperature damper is located upstream of the warm air device 400. When the cold end temperature damper and the hot end temperature damper are in different positions, the directions of the external circulation airflow 10 and the internal circulation airflow 20 in the ventilation space will change.

[0069] When the air conditioning system is in heating mode, the cold end temperature damper is closed and the hot end temperature damper is opened. The external circulation airflow 10 and the internal circulation airflow 20 pass through the air inlet 110, the adsorption device 300, the evaporator 200, the adsorption device 300, the hot end temperature damper and the heating device 400 in sequence, and then flow out of the ventilation space from the air outlet. Among them, the opening of the hot end temperature damper can be adjusted to adjust the air volume of the external circulation airflow 10 and the internal circulation airflow 20 entering the heating device 400. The heating device 400 can exchange heat with the external circulation airflow 10 and the internal circulation airflow 20 to achieve the purpose of heating. The outlet air temperature is related to the heating power of the heating device 400. When the heating power of the heating device 400 increases, the outlet air temperature of the air outlet also increases; when the heating power of the heating device 400 decreases, the outlet air temperature of the air outlet also decreases.

[0070] When the air conditioning system is in cooling mode, the cold end temperature damper is opened and the hot end temperature damper is closed. The external circulation airflow 10 and the internal circulation airflow 20 flow out of the ventilation space from the air outlet after passing through the air inlet 110, the adsorption device 300, the evaporator 200, the adsorption device 300 and the cold end temperature damper in sequence. The opening of the cold end temperature damper can be adjusted to adjust the air volume of the external circulation airflow 10 and the internal circulation airflow 20 entering the air outlet. By adjusting the refrigeration power of the evaporator 200, the outlet air temperature of the air outlet can be adjusted. The evaporator 200 can exchange heat with the external circulation airflow 10 and the internal circulation airflow 20 to achieve the purpose of refrigeration. When the refrigeration power of the evaporator 200 increases, the outlet air temperature of the air outlet decreases; when the refrigeration power of the evaporator 200 decreases, the outlet air temperature of the air outlet increases.

[0071] Furthermore, the multiple air outlets in the present embodiment are respectively the defrost air outlet 121, the front face air outlet 122, the front foot air outlet 123, the rear face air outlet 124 and the rear foot air outlet 125. The defrost air outlet 121, the front face air outlet 122, the front foot air outlet 123, the rear face air outlet 124 and the rear foot air outlet 125 are respectively arranged at various places of the vehicle body, and hot air or cold air is delivered to various positions in the vehicle cabin through the above-mentioned air outlets. For example, the defrost air outlet 121 is arranged in the front row of the vehicle body and close to the window. The air flow blown out by the defrost air outlet 121 can flow to the window to avoid fogging; the front face air outlet 122 and the front foot air outlet 123 are arranged in the front row of the vehicle body, and the front face air outlet 122 is aimed at the face of the driver or the passenger, and the front foot air outlet 123 is aimed at the feet of the driver or the passenger; the rear face air outlet 124 and the rear foot air outlet 125 are arranged in the rear row of the vehicle body, and the rear face air outlet 124 is aimed at the face of the passenger, and the rear foot air outlet 125 is aimed at the feet of the passenger.

[0072] The defrost air outlet 121 is provided with a defrost damper 1211, the front face air outlet 122 is provided with a front face damper 1221, the front foot air outlet 123 is provided with a front foot damper 1231, the rear face air outlet 124 is provided with a rear face damper 1241, and the rear foot air outlet 125 is provided with a rear foot damper 1251. The openings of the defrost damper 1211, the front face damper 1221, the front foot damper 1231, the rear face damper 1241 and the rear foot damper 1251 are all adjustable. By adjusting the openings of the defrost damper 1211, the front face damper 1221, the front foot damper 1231, the rear face damper 1241 and the rear foot damper 1251, the air volumes of the defrost air outlet 121, the front face air outlet 122, the front foot air outlet 123, the rear face air outlet 124 and the rear foot air outlet 125 can be adjusted respectively to meet different cooling and heating needs. It should be noted that when the air-conditioning system is in the heating mode, the air flows out of the defrost air outlet 121, the front face air outlet 122, the front foot air outlet 123, the rear face air outlet 124 and the rear foot air outlet 125 are the external circulation air flow 10 and the internal circulation air flow 20 that pass through the hot end temperature damper and the heating device 400, and are heated by the heating device 400, and the output air is all hot air; when the air-conditioning system is in the cooling mode, the air flows out of the defrost air outlet 121, the front face air outlet 122, the front foot air outlet 123, the rear face air outlet 124 and the rear foot air outlet 125 are the external circulation air flow 10 and the internal circulation air flow 20 that pass through the evaporator 200 and the cold end temperature damper, and are cooled by the evaporator 200, and the output air is all cold air.

[0073] This embodiment provides an air conditioning system, including an air conditioning air inlet box and the above-mentioned air conditioning distribution box. The air conditioning air inlet box is a single-layer air conditioning air inlet box, and the air conditioning air inlet box includes a ventilation channel, the ventilation channel includes an inlet and an outlet, and the outlet of the ventilation channel is connected to the air inlet 110 of the air conditioning distribution box. The external circulation airflow 10 and the internal circulation airflow 20 flow into the ventilation channel through the inlet of the air conditioning air inlet box, then enter the ventilation space of the air conditioning distribution box through the outlet, and finally are discharged from the outlet.

[0074] By arranging the adsorption device 300 in the ventilation space of the air conditioning distribution box, the adsorption device 300 can effectively adsorb CO2 and water in the internal circulation airflow 20, greatly reducing the content of CO2 and water in the internal circulation airflow 20, thereby avoiding fogging of the car windows as much as possible and avoiding causing drowsiness in the driver and passengers. At the same time, because the proportion of the internal circulation airflow 20 in the total air intake can be appropriately increased, the heat in the internal circulation airflow 20 can be fully utilized, which plays a good energy-saving role.

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.
