Description

Technical Field

[0001] This invention belongs to the field of vehicle technology, and specifically relates to a vehicle. Background Technology

[0002] Traditionally, most bus air conditioners are located on the roof, increasing the overall height of the bus, causing difficulty in passing in certain situations, and are also unsightly. Currently, some buses on the market have rear-mounted air conditioners, placing the unit at the rear of the bus, integrating it with the overall design. However, airflow from the rear of the bus has a longer delivery distance, resulting in higher temperatures for the air reaching the front. Furthermore, the presence of the windshield and side windows increases the load on the front of the bus, further raising the air temperature there. To improve driver comfort, the driver will lower the air conditioning setting, but the load on the middle and rear of the bus is less than that at the front, resulting in lower temperatures for passengers. Additionally, the driver's lowering of the air conditioning setting increases the overall energy consumption of the bus's air conditioning system. Summary of the Invention

[0003] Therefore, the present invention provides a vehicle that overcomes the shortcomings of rear-mounted bus air conditioners, which have a long air delivery distance and high air temperature at the front of the bus. In order to improve their own comfort, the driver will lower the air conditioner setting temperature as much as possible, which will result in lower temperatures in the middle and rear of the bus, making passengers feel uncomfortable.

[0004] To address the aforementioned problems, the present invention provides a vehicle including an air conditioning system disposed at the rear of the vehicle. The air conditioning system includes a low-temperature evaporator and a high-temperature evaporator. A first air supply duct and a second air supply duct extending along the length of the vehicle are disposed within the vehicle. The low-temperature evaporator corresponds to the first air supply duct, and the high-temperature evaporator corresponds to the second air supply duct. The vehicle includes a first region at the front of the vehicle and a second region at the rear of the vehicle. Air supply in the first air supply duct is directed to the first region, and air supply in the second air supply duct is directed at least to the second region.

[0005] In some embodiments, the air conditioning system further includes a first throttling element and a second throttling element, wherein the first throttling element and a low-temperature evaporator are disposed on a first branch, the high-temperature evaporator is disposed on a second branch, the second throttling element is disposed on a main branch, the first branch and the second branch are connected in parallel, and the main branch is simultaneously connected to both the first branch and the second branch.

[0006] In some embodiments, the first air supply channel has a plurality of first air outlets located in the first area, and each of the first air outlets is arranged sequentially at intervals along the extension direction of the first air supply channel.

[0007] In some embodiments, the second air supply channel has a plurality of second air outlets located in the first region and the second region respectively, and each of the second air outlets is arranged sequentially at intervals along the extension direction of the second air supply channel.

[0008] In some embodiments, the second air supply duct has a plurality of second air outlets located in the second region, and each of the second air outlets is arranged sequentially at intervals along the extension direction of the second air supply duct.

[0009] In some embodiments, the first air supply channel and the second air supply channel are arranged side by side and are adjacent to each other.

[0010] In some embodiments, a first receiving cavity is also included, in which the low-temperature evaporator is located, and the first receiving cavity is connected to the first air supply channel.

[0011] In some embodiments, there are two first air supply channels, which are respectively located on the left and right sides of the vehicle. There are also two first receiving cavities, which are respectively connected to the two first air supply channels. The low-temperature evaporator extends from one of the first receiving cavities to the other first receiving cavity.

[0012] In some embodiments, a second receiving cavity is also included, in which the high-temperature evaporator is located, and the second receiving cavity is connected to the second air supply channel.

[0013] In some embodiments, there are two second air supply channels, which are respectively located on the left and right sides of the vehicle. There are also two second receiving cavities, which are respectively connected to the two second air supply channels. The high-temperature evaporator extends from one of the second receiving cavities to the other.

[0014] This invention provides a vehicle in which a low-temperature evaporator corresponds to a first air supply duct and a high-temperature evaporator corresponds to a second air supply duct. Therefore, when air is supplied to the front of the vehicle through the first air supply duct and to the middle and rear of the vehicle through the second air supply duct, or when air is supplied to the front of the vehicle through the first air supply duct and to the front, middle and rear of the vehicle through the second air supply duct, it is equivalent to using different air ducts to deliver cold air of different temperatures. The cold air with a low supply temperature is delivered to the front of the vehicle where the load is high, and the cold air with a high supply temperature is delivered to the middle and rear of the vehicle where the load is low. This ensures that the temperature at the front, middle and rear of the vehicle is basically the same, overcoming the shortcomings of drivers lowering the supply temperature to improve comfort, resulting in lower temperatures in the middle and rear of the vehicle and discomfort for passengers. This improves the energy efficiency of the air conditioning system and the overall energy efficiency of the vehicle. Attached Figure Description

[0024] See also Figures 1 to 7As shown, according to an embodiment of the present invention, a vehicle is provided, including an air conditioning system disposed at the rear of the vehicle. The air conditioning system includes a low-temperature evaporator 3 and a high-temperature evaporator 4. A first air supply duct 5 and a second air supply duct 6 extending along the length of the vehicle are provided inside the vehicle. The low-temperature evaporator 3 corresponds to the first air supply duct 5, and the high-temperature evaporator 4 corresponds to the second air supply duct 6. The vehicle also includes a first region at the front of the vehicle and a second region at the rear of the vehicle. The air supplied in the first air supply duct 5 is directed to the first region, and the air supplied in the second air supply duct 6 is directed to at least the second region. In this technical solution, the first region of the vehicle is the front of the vehicle, especially the area where the driver is located, and the second region of the vehicle is the middle and rear of the vehicle, which is basically the area where the passengers are located. When the air conditioning system is cooling, the evaporation temperature of the refrigerant in the low-temperature evaporator 3 is lower, and the evaporation temperature of the refrigerant in the high-temperature evaporator 4 is higher. Therefore, the air temperature blown out from the low-temperature evaporator 3 is lower than the air temperature blown out from the high-temperature evaporator 4. Since the low-temperature evaporator 3 corresponds to the first air supply duct 5 on the vehicle, and the high-temperature evaporator 4 corresponds to the second air supply duct 6 on the vehicle, when air is supplied to the front of the vehicle through the first air supply duct 5 and to the middle and rear of the vehicle through the second air supply duct 6, or when air is supplied to the front of the vehicle through the first air supply duct 5 and to the front, middle and rear of the vehicle through the second air supply duct 6, it is equivalent to using different air ducts to deliver cold air of different temperatures. The cold air with a low supply temperature is delivered to the front of the vehicle with a heavy load, and the cold air with a high supply temperature is delivered to the middle and rear of the vehicle with a light load. This ensures that the temperature at the front, middle and rear of the vehicle is basically the same, overcoming the shortcoming that the driver lowers the supply temperature to improve comfort, resulting in a lower temperature in the middle and rear of the vehicle and making passengers feel uncomfortable. This improves the energy efficiency of the air conditioning system and the overall energy efficiency of the vehicle.

[0025] Specifically, the air conditioning system also includes a first throttling element 1 and a second throttling element 2. The first throttling element 1 and the low-temperature evaporator 3 are located on the first branch, the high-temperature evaporator 4 is located on the second branch, and the second throttling element 2 is located on the main flow path. The first and second branches are connected in parallel, and the main flow path is connected to both the first and second branches. When the air conditioning system is cooling, the high-temperature and high-pressure refrigerant gas discharged from the compressor 14 first enters the condenser 13 for heat exchange, and then flows from the condenser 13 into the second throttling element 2 for the first throttling. After the first throttling, the refrigerant is divided into two parallel paths: one flows into the high-temperature evaporator 4, and the other flows into the first throttling element 1 for the second throttling. After the second throttling, the refrigerant then flows into the low-temperature evaporator 3, thereby achieving a lower air temperature at the low-temperature evaporator 3 than at the high-temperature evaporator 4. Preferably, both the first throttling element 1 and the second throttling element 2 are electronic expansion valves.

[0026] See also Figure 4 and Figure 6As shown, the first air supply duct 5 has multiple first air outlets 7 located in the first area, and each first air outlet 7 is arranged sequentially at intervals along the extension direction of the first air supply duct 5. Each first air outlet 7 is only arranged at the front of the bus, and its air volume is relatively small. The arrangement of each first air outlet 7 ensures that the first air supply duct 5 only supplies air to the front of the bus.

[0027] See also Figure 4 and Figure 6 As shown, the second air supply duct 6 has multiple second air outlets 8 located in the first and second regions, respectively. These second air outlets 8 are arranged sequentially at intervals along the extension direction of the second air supply duct 6. The second air outlets 8 are evenly distributed throughout the entire second air supply duct 6, meaning they are evenly arranged at the front, middle, and rear of the bus. The second air outlets 8 have a large air volume, and their arrangement ensures that the air supplied by the second air supply duct 6 is evenly distributed throughout the entire passenger compartment. Simultaneously, both the first air supply duct 5 and the second air supply duct 6 supply air to the front of the bus, increasing the air volume at the front of the bus.

[0028] In another embodiment, the second air supply duct 6 has multiple second air outlets 8 located in the second area, and each second air outlet 8 is arranged sequentially at intervals along the extension direction of the second air supply duct 6. When the second air supply duct 6 only has multiple second air outlets 8 located in the middle and rear of the bus, the second air supply duct 6 can also supply air to the middle and rear of the bus. In this case, only the first air supply duct 5 supplies air to the front of the bus.

[0029] See also Figure 5 As shown, the first air supply channel 5 and the second air supply channel 6 are arranged side by side and are close to each other, making the air supply channel group consisting of the first air supply channel 5 and the second air supply channel 6 have a compact structure.

[0030] See also Figure 2 As shown, it also includes a first receiving cavity 9, in which the low-temperature evaporator 3 is located, and the first receiving cavity 9 is connected to the first air supply channel 5. By setting the first receiving cavity 9, it is convenient to blow the cold energy generated by the low-temperature evaporator 3 into the first air supply channel 5.

[0031] In one specific implementation, there are two first air supply channels 5, which are respectively located on the left and right sides of the vehicle. There are also two first receiving cavities 9, which are respectively connected to the two first air supply channels 5. The low-temperature evaporator 3 extends from one of the first receiving cavities 9 to the other first receiving cavity 9. Figure 2The diagram shows a top view of the air conditioning system. The first receiving cavity 9 on the left connects to the first air supply duct 5 on the left side of the vehicle, and the first receiving cavity 9 on the right connects to the first air supply duct 5 on the right side of the vehicle. In the diagram, the low-temperature evaporator 3 extends from the first receiving cavity 9 on the left to the first receiving cavity 9 on the right. A fan can simultaneously blow the cooling energy generated by the low-temperature evaporator 3 into both the left and right first air supply ducts 5. By providing two first air supply ducts 5 on the left and right sides inside the vehicle, the front of the bus can receive airflow from both sides, accelerating the cooling speed of the front of the bus.

[0032] See also Figure 2 As shown, it also includes a second receiving cavity 10, in which the high-temperature evaporator 4 is located, and the second receiving cavity 10 is connected to the second air supply channel 6. By providing the second receiving cavity 10, it is convenient to blow the cooling energy generated by the high-temperature evaporator 4 into the second air supply channel 6.

[0033] In one specific implementation, there are two second air supply channels 6, which are respectively located on the left and right sides of the vehicle. There are also two second receiving cavities 10, which are respectively connected to the two second air supply channels 6. The high-temperature evaporator 4 extends from one of the second receiving cavities 10 to the other second receiving cavity 10. Figure 2 The diagram shows a top view of the air conditioning system. The second receiving cavity 10 on the left connects to the second air supply duct 6 on the left side of the vehicle, and the second receiving cavity 10 on the right connects to the second air supply duct 6 on the right side of the vehicle. The high-temperature evaporator 4 extends from the left second receiving cavity 10 to the right second receiving cavity 10. A fan can simultaneously blow the cooling energy generated by the high-temperature evaporator 4 into both the left and right second air supply ducts 6. By providing two second air supply ducts 6 on the left and right sides within the vehicle, the entire bus compartment can receive airflow from both sides, accelerating the cooling process within the bus compartment.

[0034] See also Figures 4 to 7 As shown, the first air supply duct 5 and the second air supply duct 6 on the left side of the carriage are arranged side by side to form the left air supply duct group 11, and the first air supply duct 5 and the second air supply duct 6 on the right side of the carriage are arranged side by side to form the right air supply duct group 12.

[0035] The two heat exchangers in this application correspond to two different air supply channels, allowing for different air supply temperatures at the front of the vehicle compared to the middle and rear, which can also be applied when the air conditioner is heating. Furthermore, circuit modifications for both cooling and heating purposes are within the scope of this application, such as adding recooling, reheating, gas replenishment, or multi-stage compression to the air conditioning system.
