[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0049] The core of the present invention is to provide an air conditioning system for rail vehicles, which can effectively eliminate the peculiar smell inside the rail vehicles. Another core of the present invention is to provide a control method for the air conditioning system for rail vehicles applied to the above-mentioned air conditioning system for rail vehicles, which can effectively eliminate the peculiar smell inside the rail vehicles. Another core of the present invention is to provide a rail vehicle including the above-mentioned air conditioning system for rail vehicles, which can eliminate the peculiar smell inside the vehicle.

[0050] Please refer to Figure 1 , an embodiment of the present invention provides an air conditioning system for rail vehicles, including an air conditioning unit 1, a first fragrance-making device 2 and a second fragrance-making device 3. The air conditioning unit 1 is used to be installed in the carriage of the rail vehicle to supply air to the passenger compartment 8 and the toilet 9 of the rail vehicle. The air conditioning unit 1 includes a passenger compartment air supply duct and a toilet air supply duct; both the first fragrance-making device 2 and the second fragrance-making device 3 are used to generate aromatherapy. The first fragrance-making device 2 is arranged in the passenger compartment air supply duct; the second fragrance-making device 3 is arranged in the toilet air supply duct.

[0051] During operation, the first fragrance-making device 2 generates aromatherapy. The air conditioning unit 1 supplies fresh air to the passenger compartment 8 through the passenger compartment air supply duct. Since the first fragrance-making device 2 is arranged in the passenger compartment air supply duct, the aromatherapy generated by the first fragrance-making device 2 will be transported into the passenger compartment 8 along with the fresh air transported by the passenger compartment air supply duct. Thus, the air in the passenger compartment 8 can be purified by the aromatherapy to eliminate the peculiar smell in the passenger compartment 8, create a comfortable and clean riding environment, and improve the riding experience of passengers. In addition, the second fragrance-making device 3 generates aromatherapy. The air conditioning unit 1 supplies fresh air to the toilet 9 through the toilet air supply duct. Since the second fragrance-making device 3 is arranged in the toilet air supply duct, the aromatherapy generated by the second fragrance-making device 3 will be transported into the toilet 9 along with the fresh air transported by the toilet air supply duct. Thus, the air in the toilet 9 can be purified by the aromatherapy to eliminate the peculiar smell in the toilet 9 and keep the air in the toilet 9 fresh.

[0052] That is to say, in this embodiment, the first fragrance-making device 2 and the second fragrance-making device 3 are respectively arranged in the passenger compartment air supply duct and the toilet air supply duct. While supplying fresh air to the passenger compartment 8 through the passenger compartment air supply duct, the fragrance generated by the first fragrance-making device 2 is sent into the passenger compartment 8, and while supplying fresh air to the toilet 9 through the toilet air supply duct, the fragrance generated by the second fragrance-making device 3 is sent into the toilet 9, so as to eliminate the peculiar smell in the passenger compartment 8 and the toilet 9 by using the fragrance and keep the air fresh. Compared with simply using the fresh air supplied by the air-conditioning unit 1 to relieve the peculiar smell in the passenger compartment 8, the air-conditioning system for rail vehicles provided by the embodiment of the present invention has a better effect of eliminating the peculiar smell and is beneficial to keeping the air fresh; moreover, by separately controlling the first fragrance-making device 2 and the second fragrance-making device 3, the environment of the passenger compartment 8 and the toilet 9 can be controlled independently in zones, so as to achieve the purpose of controlling the air quality of the passenger compartment 8 and the toilet 9 in zones, which is beneficial to controlling according to the respective characteristics of the passenger compartment 8 and the toilet 9.

[0053] It should be noted that the specific structures and working principles of the first fragrance-making device 2 and the second fragrance-making device 3 in this embodiment are not limited, as long as the first fragrance-making device 2 and the second fragrance-making device 3 can generate fragrance. For example, the first fragrance-making device 2 and the second fragrance-making device 3 can be fragrance lamps, fragrance candles or essential oil volatilizers respectively. Exemplarily, the first fragrance-making device 2 and the second fragrance-making device 3 can be diffusers respectively. The specific structure and working principle of the diffuser can refer to the related technology. For example, the diffuser can utilize the principle of high-speed flow of compressed air to convert the fragrance liquid into fine particles, and then use the ion high-speed rotary accelerator to impact the fragrance essential oil particles into tiny particles for diffusion. This kind of diffuser has a high fragrance concentration, a wide diffusion range and a better effect of eliminating peculiar smell.

[0054] In addition, the first fragrance-making device 2 and the second fragrance-making device 3 can respectively have multiple gears, and the atomization amount of the fragrance can be controlled by respectively adjusting the gears of the first fragrance-making device 2 and the second fragrance-making device 3. For example, the diffuser can have ten gears, and by adjusting different gears, the diffuser has different fragrance atomization amounts. In addition, the essential oil capacity of the first fragrance-making device 2 and the second fragrance-making device 3 in the embodiment of the present invention is not limited. For example, the essential oil capacity of the diffuser is 150 ml. If the working gear of the diffuser is between the third gear and the fifth gear, then the essential oil of this capacity can be used for 60 to 90 days.

[0055] In addition, the first fragrance-making device 2 and the second fragrance-making device 3 can be automatically controlled by the control device, or can be manually controlled by the crew.

[0056] In addition, the specific installation position of the first fragrance-making device 2 in the above embodiments is not limited, as long as the fragrance produced by the first fragrance-making device 2 can be sent into the passenger compartment 8 along with the fresh air conveyed by the passenger compartment air supply duct.

[0057] As Figure 1 shown, in some embodiments, the passenger compartment air supply duct includes a passenger compartment main duct 41 and at least one passenger compartment branch duct 42 communicating with the passenger compartment main duct 41, and the first fragrance-making device 2 is arranged in the passenger compartment main duct 41.

[0058] That is to say, in this embodiment, by arranging the first fragrance-making device 2 in the passenger compartment main duct 41, the fragrance produced by the first fragrance-making device 2 is sent along with the air supply of the passenger compartment main duct 41 into each passenger compartment branch duct 42, and then is sent into each area of the passenger compartment 8 through each passenger compartment branch duct 42. That is, each passenger compartment branch duct 42 shares the same first fragrance-making device 2, which is beneficial to saving the number of the first fragrance-making devices 2 and ensuring the uniformity of the fragrance in each area of the passenger compartment 8.

[0059] In addition, it should be noted that the fragrance liquid selected for the first fragrance-making device 2 can be a fragrance with a relatively low concentration and a soothing effect, for example, lavender fragrance or chamomile fragrance, etc.

[0060] In addition, the specific installation position of the second fragrance-making device 3 in the above embodiments is not limited, as long as the fragrance produced by the second fragrance-making device 3 can be sent into the toilet 9 along with the fresh air conveyed by the toilet air supply duct.

[0061] As Figure 1 shown, in some embodiments, the toilet air supply duct includes a toilet main duct 51 and at least one toilet branch duct 52 communicating with the toilet main duct 51, and the second fragrance-making device 3 is arranged in the toilet branch duct 52.

[0062] That is to say, in this embodiment, by arranging the second fragrance-making device 3 in each toilet branch duct 52, the fragrance of each second fragrance-making device 3 is respectively sent into the corresponding toilet 9 through the air supply of each toilet branch duct 52, so that each toilet 9 independently corresponds to an independent second fragrance-making device 3, which is beneficial to separately and independently controlling the second fragrance-making device 3 corresponding to each toilet 9, ensuring the required amount of fragrance for each toilet 9, and achieving a better effect of removing odors in each toilet 9.

[0063] It should be noted that the fragrance liquid selected for the second fragrance-making device 3 can be a fragrance with a relatively high concentration and a deodorizing effect, for example, tea tree fragrance or eucalyptus fragrance, etc.

[0064] In addition, as Figure 1As shown, in some embodiments, the air conditioning system for rail vehicles further includes a toilet waste exhaust duct 61. The toilet waste exhaust duct 61 is provided in the toilet 9 of the rail vehicle, and the waste exhaust air volume of the toilet waste exhaust duct 61 is greater than the fresh air volume of the toilet air supply duct.

[0065] That is to say, in this embodiment, local control is performed on the air flow in the toilet 9, so that the waste exhaust air volume of the toilet waste exhaust duct 61 is greater than the fresh air volume of the toilet air supply duct, thereby creating a negative pressure in the toilet 9, which is beneficial to removing the peculiar smell in the toilet 9 and achieving a better purpose of purifying the air in the toilet 9. At the same time, it can prevent the fragrance smell in the toilet 9 from flowing into the passenger compartment 8.

[0066] In addition, as Figure 1 shown, considering the specific layout of the air conditioning unit 1, the passenger compartment air supply duct, the waste exhaust device 7, and the passenger compartment waste exhaust duct 62, in some embodiments, the air conditioning unit 1 is an embedded unit type air conditioning unit, and the air conditioning unit 1 is provided on the roof at the end of each carriage of the rail vehicle; the passenger compartment air supply duct is provided at the top of the side of the carriage; the air conditioning system for rail vehicles further includes a waste exhaust device 7 and a passenger compartment waste exhaust duct 62. The waste exhaust device 7 is provided in the undercarriage equipment compartment of the rail vehicle; the passenger compartment waste exhaust duct 62 is connected to the waste exhaust device 7, and the passenger compartment waste exhaust duct 62 is provided at the bottom of the side wall of the rail vehicle carriage.

[0067] It can be understood that the embedded unit type air conditioning unit is beneficial to saving space; the air conditioning unit 1 is provided on the roof at the end of each carriage of the rail vehicle and the passenger compartment waste exhaust duct 62 is provided at the bottom of the side wall of the rail vehicle carriage, which is beneficial to optimizing the air supply path, facilitating the improvement of the smoothness of air supply and waste exhaust, and is beneficial to ensuring the uniformity of air supply in the passenger compartment 8; the setting of the waste exhaust device 7 is beneficial to discharging waste exhaust gas.

[0068] Please refer to Figure 2 , in addition to the above air conditioning system for rail vehicles, the embodiment of the present invention also provides a control method for an air conditioning system for rail vehicles. The control method for the air conditioning system for rail vehicles is applied to the air conditioning system for rail vehicles disclosed in any of the above embodiments. The control method for the air conditioning system for rail vehicles includes:

[0069] S11: When the external temperature range of the rail vehicle is , control the fresh air volume of the air conditioning unit 1 to be , and control the first fragrance making device 2 to operate in the fourth gear; wherein, the first fragrance making device 2 includes at least four gears, and the higher the gear of the first fragrance making device 2, the greater the fragrance concentration produced by the first fragrance making device 2; wherein, Te represents the external temperature of the rail vehicle.

[0070] S12: When the external temperature range of the rail vehicle is or When the time is , control the fresh air volume of the air conditioner unit 1 to be

[0071] S13: When the external temperature range of the rail vehicle is or When the time is , control the fresh air volume of the air conditioner unit 1 to be

[0072] That is to say, in this embodiment, the gear of the first incense making device 2 and the fresh air volume of the air conditioner unit 1 are controlled according to the external temperature of the rail vehicle, and the gear of the first incense making device 2 is matched with the fresh air volume of the air conditioner unit 1, so as to make the aromatherapy concentration in the passenger compartment 8 adapt to the external temperature of the rail vehicle by the combined action of the fresh air volume of the air conditioner unit 1 and the first incense making device 2, so as to create a better riding environment.

[0073] Further, in some embodiments, the control method of the air conditioning system for rail vehicles further includes: when the rail vehicle triggers the pressure wave protection function, if the pressure wave duration exceeds the first preset time, control the first incense making device 2 to operate in the first gear; when the pressure wave protection function is released, control the first incense making device 2 to maintain in the first gear for the second preset time; when the pressure wave protection function is triggered again within the second preset time, control the first incense making device 2 to maintain in the first gear; when the pressure wave protection function is not triggered again within the second preset time, control the working gear of the first incense making device 2 according to the external temperature of the rail vehicle.

[0074] It can be understood that when the rail vehicle triggers the pressure wave protection function, the air conditioner unit 1 will close the fresh air and exhaust valves. At this time, time accumulation can be carried out. When the pressure wave duration exceeds the first preset time, the first incense making device 2 is forced to operate in the first gear; when the pressure wave protection function is released, control the first incense making device 2 to keep operating in the first gear for the second preset time. If the pressure wave protection function is triggered again within the second preset time, control the first incense making device 2 to remain in the first gear unchanged. If the pressure wave protection function is not triggered again within the second preset time, the control strategy of controlling the working gear of the first incense making device 2 according to the external temperature of the rail vehicle as described above can be adopted for control.

[0075] It should be noted that the specific durations of the first preset time and the second preset time in this embodiment are not limited. For example, the first preset time can be 3 min, and the second preset time can also be 3 min. That is, when the pressure wave duration exceeds 3 min, the first incense making device 2 is forced to operate in the first gear; when the pressure wave protection function is released, control the first incense making device 2 to keep operating in the first gear for 3 min. Of course, the first preset time and the second preset time can also be other durations.

[0076] It should be noted that the first gear, second gear, third gear, and fourth gear of the first incense-making device 2 in the embodiments of the present invention are relative concepts, which only represent the different working gears corresponding to the first incense-making device 2 and the relative relationships between different working gears under different conditions. For example, when the first incense-making device 2 only includes four gears, the four gears are the first gear, second gear, third gear, and fourth gear respectively. When the external temperature range of the rail vehicle is at this time, control the first incense-making device 2 to work in the fourth gear; when the external temperature range of the rail vehicle is or at this time, control the first incense-making device 2 to work in the third gear; when the external temperature range of the rail vehicle is or at this time, control the first incense-making device 2 to work in the second gear; when the rail vehicle triggers the pressure wave protection function and the duration of the pressure wave exceeds the first preset time, control the first incense-making device 2 to work in the first gear.

[0077] When the first incense-making device 2 includes at least five gears, the first gear, second gear, third gear, and fourth gear are relative concepts. For example, the first incense-making device 2 includes ten gears, which are the first gear to the tenth gear respectively. The higher the gear, the greater the concentration of the aromatherapy; at this time, the first gear can be the second gear, the second gear can be the third gear, the third gear can be the fourth gear, and the fourth gear can be the fifth gear. Of course, the first gear, second gear, third gear, and fourth gear can also be other corresponding gears, as long as it can ensure that the concentration of the aromatherapy in the first gear is less than that in the second gear, the concentration of the aromatherapy in the second gear is less than that in the third gear, and the concentration of the aromatherapy in the third gear is less than that in the fourth gear.

[0078] In addition, please refer to Figure 3 , in some embodiments, the control method of the air-conditioning system for rail vehicles further includes:

[0079] S21: After the rail vehicle is powered on, control the second incense-making device 3 to work for a third preset time.

[0080] That is to say, after the rail vehicle is started, forcibly control the second incense-making device 3 to work for a third preset time to pre-eliminate the odor in the toilet 9. It should be noted that the specific duration of the third preset time in this embodiment is not limited. For example, the third preset time can be 10 minutes, that is, after the rail vehicle is powered on, control the second incense-making device 3 to start working and forcibly control the second incense-making device 3 to work for 10 minutes.

[0081] Further, in some embodiments, the air conditioning system for rail vehicles further includes a sensing device for sensing whether there is anyone in the toilet 9; the control method of the air conditioning system for rail vehicles further includes:

[0082] S22: When the sensing device senses that there is someone in the toilet 9, control the second fragrance-making device 3 to start working.

[0083] S23: When the sensing device senses that the person has left, control the second fragrance-making device 3 to continue working for a fourth preset time.

[0084] That is to say, in this embodiment, by monitoring the entry and exit of people in the toilet 9, the second fragrance-making device 3 is controlled to achieve the removal of the peculiar smell in the toilet 9. That is, when the sensing device senses that there is someone, the second fragrance-making device 3 starts working. When the sensing device senses that the person has left, control the second fragrance-making device 3 to continue working for a fourth preset time. If someone is sensed at the fourth preset time, control the second fragrance-making device 3 to continue working. When no one is sensed after the fourth preset time, control the second fragrance-making device 3 to stop working. Wait until someone is detected again next time, and then control the second fragrance-making device 3 to start working.

[0085] That is, the second fragrance-making device 3 works intermittently and is turned on according to the entry and exit of people.

[0086] It should be noted that the specific duration of the fourth preset time in this embodiment is not limited. For example, the fourth preset time can be 5 minutes. That is, when the sensing device senses that the person has left, control the second fragrance-making device 3 to continue working for 5 minutes.

[0087] In addition to the above air conditioning system for rail vehicles and its control method, the present invention also provides a rail vehicle including the air conditioning system for rail vehicles disclosed in the above embodiments.
