[0028] The embodiments of this utility model 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 intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] The following is for reference. Figures 1-3 The present invention describes an air conditioning system 100 for a vehicle according to a first aspect of the present invention.

[0030] like Figures 1-3 As shown, the vehicle air conditioning system 100 according to the first aspect embodiment of the present invention includes: a temperature regulating component 10, a first air duct 20, a first fan, a second air duct 30, a second fan, and a control unit.

[0031] Specifically, the temperature regulating component 10 is used to adjust the temperature of the airflow passing through the temperature regulating component 10. The first air duct 20 is located in the ceiling and is adapted to communicate with the temperature regulating component 10. The first fan is located in the first air duct 20. The ceiling has a first air vent 21 connecting the first air duct 20 and the passenger compartment. The second air duct 30 is located in the floor and is adapted to communicate with the temperature regulating component 10. The second fan is located in the second air duct 30. The floor has a second air vent 31 connecting the second air duct 30 and the passenger compartment. The temperature regulating component 10, the first fan, and the second fan are all electrically connected to the control unit.

[0032] The temperature regulating component 10 can heat or cool the airflow. It may include a heat pump device, such as an evaporator, condenser, compressor, and expansion valve, which heats the airflow passing through it. The temperature regulating component 10 may also include an electric heating element that heats the airflow. Furthermore, it may be equipped with an air duct connected to the engine system, utilizing the heat from the engine system to heat the airflow.

[0033] During vehicle operation, the control unit controls the connection between the first air duct 20 and the second air duct 30. The first air duct 20, the temperature regulating component 10, and the second air duct 30 constitute an airflow path. The control unit controls the first fan and the second fan to generate negative pressure in the direction of the airflow path extension, causing the airflow to flow in the same direction. Thus, one of the first air inlet 21 and the second air inlet 31 becomes an air inlet, and the other becomes an air outlet. The air in the passenger compartment enters the airflow path from the air inlet, and after heat exchange by the temperature regulating component 10, the heat-exchanged airflow is blown out from the air outlet, thereby achieving the regulation of the temperature in the passenger compartment.

[0034] Understandably, during the operation of the vehicle's air conditioning system 100, the air in the passenger compartment is gradually drawn into the aforementioned air duct and exchanges heat with the temperature regulating component 10. In this embodiment, the air inlet and air outlet are located on the upper side of the passenger compartment and the lower side of the passenger compartment, respectively. This creates a vertical circulating airflow in the passenger compartment. In the vertical direction, the airflow on one side gradually enters the air inlet and exchanges heat with the temperature regulating component 10, while the airflow on the other side gradually flows out after heat exchange. This allows the air in the passenger compartment to exchange heat with the temperature regulating component 10 more quickly and comprehensively, and the distribution of the heat-exchanged airflow in the passenger compartment is more uniform, thereby improving the temperature regulation efficiency and the uniformity of temperature distribution in the passenger compartment.

[0035] Under the same initial and target temperatures, the temperature regulation data of the air conditioning system 100 of the vehicle in the prior art and the temperature regulation data of the air conditioning system 100 of the vehicle in this embodiment are compared. Specifically, as shown in the table below, the heating efficiency and temperature uniformity of this embodiment are significantly improved. At the same time, the air outlet speed of the vehicle's air conditioning system 100 is significantly reduced during operation. This reduces airflow noise in the passenger compartment and lowers the energy consumption of the vehicle's air conditioning system 100. It also reduces the wind sensation for the passengers. Furthermore, the vertically arranged first air vent 21 and second air vent 31 are more likely to avoid the passenger area, further reducing the wind sensation for the passengers.

[0036] Comparison items Existing technology This embodiment wind speed 3m / s-5m / s 0.5m / s-1.5m / s Temperature uniformity Maximum temperature difference > 4℃ Maximum temperature difference ≤1.5℃ Temperature rise time (-20℃→20℃) 15 minutes 8 minutes

[0037] Air density varies with temperature; air at lower temperatures has a higher density. Based on this principle, preferably, in cooling and heating modes, the first air vent 21 and the second air vent 31 can have opposite air intake directions.

[0038] For example, such as Figure 2 As shown, in cooling mode, the first air vent 21 is formed as an air outlet and the second air vent 31 is formed as an air inlet. The airflow enters the lower second air vent 31 and exchanges heat with the temperature regulating component 10 through the second air duct 30. The cooled airflow flows out from the upper first air vent 21 through the first air duct 20. The denser cold air can diffuse downwards more quickly, thereby improving the cooling efficiency in the passenger cabin.

[0039] In heating mode, such as Figure 3 As shown, the second air vent 31 is formed as an air outlet, and the first air vent 21 is formed as an air inlet. The airflow enters the upper first air vent 21 and exchanges heat with the temperature regulation component 10 through the first air duct 20. The heated airflow flows out from the lower second air vent 31 through the second air duct 30. The less dense hot air can diffuse upward more quickly, thereby improving the heating efficiency in the passenger cabin.

[0040] Preferably, the first air vent 21 and the second air vent 31 are covered with air guides and air guides, and the air guides have multiple air guide holes, which can improve the uniformity of airflow in and out of the first air vent 21 and the second air vent 31. The air guides are ceramic parts.

[0041] According to the first aspect of the present invention, the vehicle air conditioning system 100, by setting a first air vent 21 and a second air vent 31 on the ceiling and floor, during vehicle operation, the control unit can control the negative pressure direction of the first fan and the second fan, so that one of the first air vent 21 and the second air vent 31 is an air inlet and the other is an air outlet. In this way, a vertical circulating airflow can be generated in the passenger compartment, and the air in the passenger compartment can exchange heat with the temperature regulation component 10 more quickly and comprehensively. This can improve the efficiency of temperature regulation in the passenger compartment and improve the uniformity of temperature distribution in the passenger compartment. In addition, the first air vent 21 and the second air vent 31 are more likely to avoid the passenger seats, which can reduce the passenger's windy feeling.

[0042] In some embodiments of this utility model, such as Figures 1-3 As shown, the first air duct 20 extends along the front-rear direction of the vehicle, and there are multiple first air vents 21, which are arranged at intervals in the front-rear direction of the vehicle. For example, there can be two, three or four first air vents 21. In this way, during the operation of the vehicle, multiple first air vents 21 can draw in or blow air at different positions in the front-rear direction, thereby further improving the temperature regulation efficiency and temperature distribution uniformity in the passenger compartment.

[0043] In some embodiments of this utility model, such as Figures 1-3 As shown, there are multiple first air ducts 20. For example, there can be two, three or four first air ducts 20 connected in parallel, and the multiple first air ducts 20 are arranged at intervals in the left and right directions of the vehicle.

[0044] In this way, during the operation of the vehicle, multiple first air ducts 20 and the first air outlets 21 corresponding to the first air ducts 20 can draw in or blow air at different positions in the left and right directions, thereby further improving the temperature regulation efficiency and the uniformity of temperature distribution in the passenger compartment.

[0045] In some embodiments of this utility model, such as Figure 1 As shown, the first air duct 20 has a first branch 22, which extends into the side enclosure and is located in the upper part of the side enclosure. The upper part of the side enclosure is provided with a third air vent 23 connecting the first branch 22 and the crew compartment.

[0046] During vehicle operation, the third air vent 23 can draw in or blow air into the passenger compartment from the upper part of the side panel, which can further improve the temperature regulation efficiency and the uniformity of temperature distribution in the passenger compartment.

[0047] Preferably, the same first branch 22 can connect to multiple third air vents 23, one of which is oriented in the front-back direction, and another of which is oriented in the left-right direction.

[0048] The third air vent 23 is covered with an air guide, which has multiple air guide holes. This can improve the uniformity of airflow at the third air vent 23. The air guide is made of ceramic.

[0049] In some embodiments of this utility model, such as Figure 1 As shown, the vehicle's air conditioning system 100 further includes: an upper air duct 40, a first branch line 41, and a second branch line 42. The upper air duct 40 is connected between the temperature regulating assembly 10 and the first air duct 20. One end of the first branch line 41 is connected to the upper air duct 40, and the other end of the first branch line 41 extends to the side of the windshield. A first air duct 20 plate is provided inside the first branch line 41. The first air duct 20 plate is rotatably connected to the inner wall of the first branch line 41 and is adapted to block the first branch line 41. One end of the second branch line 42 is connected to the upper air duct 40, and the other end of the second branch line 42 extends to the side door glass. A second air duct 30 plate is provided inside the second branch line 42. The second air duct 30 plate is rotatably connected to the inner wall of the second branch line 42 and is adapted to block the second branch line 42.

[0050] The first air duct 20 and the second air duct 30 are each equipped with an opening and closing structure that is electrically connected to the control unit. The opening and closing structure can control the conduction state of the first air duct 20 and the second air duct 30.

[0051] When defogging of the windshield and side door windows is required, the control unit closes the second air duct 30, the first air duct 20 plate rotates to a set angle to open the first branch 41 with a set conduction area, and the second air duct 30 plate rotates to a set angle to open the second branch 42 with a set conduction area. The temperature regulating component 10 draws in air through the third air duct of the external circulation system. Part of the airflow regulated by the temperature regulating component 10 enters the first air duct 20 through the upper air duct 40 and is then blown out from the first air outlet 21. The other part is blown towards the windshield through the first branch 41 and towards the side door windows through the second branch 42. Preferably, the ratio of the airflow of the first branch 41 and the second branch 42 to the airflow before the upper air duct 40 is split is 30%.

[0052] In some embodiments of this utility model, such as Figures 1-3As shown, the second air duct 30 extends along the front-rear direction of the vehicle, and there are multiple second air vents 31, which are arranged at intervals in the front-rear direction of the vehicle. For example, there can be two, three, or four second air vents 31.

[0053] In this way, during vehicle operation, multiple secondary air vents 31 can draw in or blow air at different positions in the front and rear directions, thereby further improving the temperature regulation efficiency and temperature distribution uniformity in the passenger compartment.

[0054] In some embodiments of this utility model, such as Figures 1-3 As shown, there are multiple second air ducts 30. For example, there can be two, three or four second air ducts 30 connected in parallel, and the multiple second air ducts 30 are arranged at intervals in the left and right directions of the vehicle.

[0055] In this way, during vehicle operation, multiple second air ducts 30 and the second air outlets 31 corresponding to the second air ducts 30 can draw in or blow air at different positions in the left and right directions, thereby further improving the temperature regulation efficiency and temperature distribution uniformity in the passenger compartment.

[0056] In some embodiments of the present invention, the second air duct 30 has a second branch, which extends into the side enclosure and is located in the lower part of the side enclosure. The lower part of the side enclosure is provided with a fourth air vent connecting the second branch and the passenger compartment.

[0057] During vehicle operation, the fourth air vent can draw in or blow air into the passenger compartment from the upper part of the side panel, which can further improve the temperature regulation efficiency and the uniformity of temperature distribution in the passenger compartment.

[0058] Preferably, the fourth air vent is covered with an air guide, and the air guide has multiple air guide holes, which can improve the uniformity of airflow at the fourth air vent. The air guide is a ceramic component.

[0059] In some embodiments of this utility model, the vehicle's air conditioning system 100 further includes: a third air duct and a carbon dioxide concentration sensor. The third air duct is adapted to connect the temperature regulating component 10 and the external environment of the vehicle. The carbon dioxide concentration sensor is located in the passenger compartment and is electrically connected to the control unit.

[0060] When the vehicle is in external circulation mode, the airflow from the outside environment enters the temperature regulation component 10 through the third air duct. After the temperature regulation component 10 exchanges heat with the airflow, the heat-exchanged airflow enters the passenger compartment.

[0061] During vehicle operation, the carbon dioxide concentration sensor detects the carbon dioxide concentration inside the vehicle and transmits the data to the control unit. As the internal circulation time increases, the carbon dioxide concentration inside the vehicle will rise. When the carbon dioxide concentration reaches the threshold, the control unit controls the vehicle's air conditioning system to enter the external circulation mode. The airflow from outside the vehicle enters the passenger compartment through the third air duct, thereby achieving automatic adjustment of the air quality inside the vehicle.

[0062] A vehicle according to a second aspect of the present invention includes: the air conditioning system 100 of the vehicle according to the first aspect of the present invention.

[0063] According to the second aspect embodiment of the present invention, by providing the air conditioning system 100 of the vehicle according to the first aspect embodiment of the present invention, the temperature regulation efficiency and temperature distribution uniformity in the passenger compartment can be improved, thereby enhancing the user experience.
