Description

Technical Field

[0001] The present invention relates to the field of automotive air conditioners, and more particularly to an automotive air conditioning system and an automobile having the same. Background Art

[0002] Currently, buses, coaches, etc. are the mainstream urban public transportation means, bringing convenience to people's travel. In urban and rural transportation, buses, coaches, etc. have also become essential transportation means for people every day. However, since passengers may carry bacteria or viruses on their bodies, and some viruses or bacteria may be transmitted through the air, it may cause cross-infection among passengers in the vehicle.

[0003] For a relatively crowded transportation means such as a bus or a coach, to avoid cross-infection among people, in addition to wearing masks, it is extremely important to ensure that the circulated air in the vehicle is cleaned and sterilized in a timely manner after flowing through the passengers. Currently, buses, coaches, etc. do not have this function. Therefore, a new air conditioning system needs to be proposed to ensure safe travel for everyone in special situations such as the epidemic.

Detailed implementation manners

[0061] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, of the embodiments of the present invention. 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.

[0062] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "the" and "said" used in the embodiments of the present invention and the appended claims are also intended to include the plural forms unless the context clearly dictates otherwise. "Plural" generally includes at least two, but does not exclude the case of including at least one.

[0063] It should be understood that the term "and / or" used herein is only a description of the associated relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0064] It should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non - exclusive inclusion, so that a commodity or system including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such commodity or system. Without further limitation, the element defined by the statement "including one..." does not exclude the existence of another identical element in the commodity or system including the said element.

[0065] At present, the air in a bus may carry bacteria after flowing through passengers, which is likely to cause cross-infection problems; there are certain defects in the air duct structure after the air-conditioning system turns on the internal circulation, and it cannot well simplify the air flow direction, easily causing cross-mixing of multiple air flows; there is no disinfection module during air purification, etc. The present invention improves the existing air-conditioning system by adopting a double air duct structure arranged up and down, realizing air outlet from the lower air duct and air return from the upper air duct or air outlet from the upper air duct and air return from the lower air duct. By adding a three-way structure with dampers to freely switch the air ducts, a closed internal circulation is realized, which well adapts to the formation of a matching air flow path for internal circulation when the air conditioner is cooling / heating. In addition, the centrifugal fan of the in-vehicle air-conditioning system is used to generate negative pressure in the air return duct (upper air duct or lower air duct), and the air return in the vehicle is smooth; the air return in the vehicle can efficiently flow through the disinfection module and then circulate again to achieve sterile air.

[0066] To further elaborate on the technical solution of the present invention, in combination with Figure 1-8 , the following specific embodiments are provided.

[0067] Embodiment 1

[0068] As Figure 1-2 shown, in this embodiment, an automotive air-conditioning system is provided. There is a cabin in the vehicle. The cabin is provided with one or a row or a column or multiple rows or multiple columns of seats. An upper air duct 1, a lower air duct 2, and an air treatment chamber are arranged in the automotive cabin, where: the upper air duct is arranged above the seats in the cabin, and the upper air duct is provided with upper air duct sub-air outlets corresponding to one or a row or a column or multiple rows or multiple columns of seats. The lower air duct is arranged below the seats in the cabin, and the lower air duct is provided with lower air duct sub-air outlets corresponding to one or a row or a column or multiple rows or multiple columns of seats. Preferably, the cabin has a certain accommodation space. There is a ceiling at the upper part of the accommodation space, a floor at the lower part, and a personnel activity or seating area in the middle. The upper air duct is arranged between the ceiling of the vehicle and the top of the cabin, and the upper air duct sub-air outlets can lead into the interior of the cabin through the ceiling. The lower air duct is located between the bottom of the cabin and the floor, and the lower air duct sub-air outlets can lead into the interior of the cabin through the floor. It should be noted that: the above-mentioned one or a row or a column or multiple rows or multiple columns of seats refer to the seats arranged in sequence from the front of the vehicle to the rear, with rows being horizontal and columns being vertical.

[0069] One of the upper air duct and the lower air duct can be selectively used as the supply air duct, and the other as the return air duct. An air treatment chamber is provided between the upper air duct and the lower air duct. One side of the air treatment chamber communicates with the upper air duct, and the other side communicates with the lower air duct; an air treatment module 3 is arranged between the two sides of the air treatment chamber; the upper air duct sub-air outlet and the lower air duct sub-air outlet are controlled to form an air distribution mode of upper supply and lower return or upper return and lower supply. This air distribution mode enables each seat or each row or each column of seats to obtain an independent air flow from top to bottom or from bottom to top within its predetermined range. It should be noted that this independent air flow is a flow path with little mutual influence formed between the air outlets, which is relative to the mixed and staggered air between the existing air conditioner supply and return air outlets, and is not completely independent in the strict sense. An air flow surrounding each seat or each row or each column of seats is formed by the cooperation of the upper air duct sub-air outlet and the lower air duct sub-air outlet to prevent the diffusion of air in the cabin environment.

[0070] The vehicle air conditioning system further includes a fan assembly, a first three-way structure 4, a first air damper 71, a second three-way structure 5, and a second air damper 72. Specifically, the upper air duct 1 is provided with an upper air duct main air outlet 11 and an upper air duct sub-air outlet 12. The upper air duct sub-air outlet 12 is used to communicate with the interior of the vehicle body. The upper air duct main air outlet 11 communicates with the first port 41 of the first three-way structure and the first outlet of the fan assembly respectively; the lower air duct 2 is provided with a lower air duct main air outlet 21 and a lower air duct sub-air outlet 22. The lower air duct sub-air outlet 22 is used to communicate with the interior of the vehicle body. The lower air duct main air outlet 21 communicates with the first port 51 of the second three-way structure; the second port 42 of the first three-way structure communicates with the second port 52 of the second three-way structure; the third port 43 of the first three-way structure communicates with the inlet of the fan assembly, and the third port 53 of the second three-way structure communicates with the second outlet of the fan assembly; the first air damper 71 is used to switch and close between the first port 41 of the first three-way structure and the first outlet of the fan assembly; the second air damper 72 is used to switch and close between the second port 52 of the second three-way structure and the third port 53 of the second three-way structure; the air treatment module 3 is arranged in the air conditioning system and can perform sterilization and purification treatment on the air delivered by the air conditioning system.

[0071] For example, when the air conditioning system controls the upper air duct to supply air and the lower air duct to return air, as Figure 2 shown, the specific process includes that the second air damper 72 rotates to the second outlet of the fan assembly. At this time, the second outlet of the fan assembly is closed, and the second port 52 of the second three-way structure is opened; at the same time, the first air damper 71 rotates to the first port 41 of the first three-way structure. At this time, the first port 41 of the first three-way structure is closed, and the first outlet of the fan assembly is opened. An air flow path is formed in the air duct from the interior of the vehicle to the lower air duct 2 - the second three-way structure 5 - the first three-way structure 4 - the fan 6 - the upper air duct 1, and finally back to the interior of the vehicle. As Figure 2As shown, it is the air internal circulation flow path on one side of the air conditioning system. The arrow direction represents the air flow direction (it represents the air outlet of the upper air duct and the air return of the lower air duct). The return air (air) flow converges at the first three-way structure 4 and then flows out from the third port 43 of the first three-way structure, passes through the air treatment module 3 for disinfection, then flows into the fan 6, and finally passes through the evaporator 8 and flows into the upper air duct from the main air outlet 11 of the upper air duct on the right, completing one internal circulation. Preferably, the air treatment module 3 is arranged between the third port 43 of the first three-way structure and the inlet of the fan assembly. It should be noted that the air treatment module 3 can also be arranged in the air duct, such as in the upper air duct 1 and / or the lower air duct 2, etc., that is, it can be processed on the circulation path formed by the air conditioning system. In addition, the air treatment module 3 can be a sterilization module that only performs sterilization, or other modules that have functions such as purification and filtration alone or in combination.

[0072] In some alternative implementation manners, the fan assembly includes a wind cavity and a fan 6 arranged in the wind cavity. The inlet, the first outlet, and the second outlet of the fan assembly are formed on the wind cavity. The fan is used to provide power for the air flow in the automotive air conditioning system. Preferably, the fan 6 is a centrifugal fan. It should be noted that the fan 6 can also be other types of fans such as an axial flow fan.

[0073] Furthermore, a guide ring 9 is arranged between the fan inlet and the inlet of the fan assembly, which is used to guide the air flowing out from the third port of the first three-way structure only to the fan inlet.

[0074] In this embodiment, the air conditioning system further includes an evaporator 8, which is used to exchange heat with the air sent out by the fan assembly. Optionally, the evaporator 8 is arranged in the wind cavity. At this time, the evaporator 8 needs to satisfy being located between the outlet of the fan and the first outlet, and also needs to satisfy being located between the outlet of the fan and the second outlet. As Figure 4 shown, the evaporator 8 adopts a curved plate-like structure, which can ensure effective heat exchange with the air flowing through the first outlet or the second outlet.

[0075] In some manners, the upper air duct 1 and the lower air duct are arranged up and down, where: there are multiple upper air duct sub-air outlets 12, and they are arranged in sequence along the extending direction of the upper air duct 1; there are multiple lower air duct sub-air outlets 22, and they are arranged in sequence along the extending direction of the lower air duct 2. Preferably: the upper air duct sub-air outlets 12 and the lower air duct sub-air outlets 22 are in one-to-one correspondence. This manner can reduce or avoid cross-mixing when air flows between the upper air duct sub-air outlets 12 and the lower air duct sub-air outlets 22. Further preferably: exhaust fans are arranged in the upper air duct sub-air outlets 12 and / or the lower air duct sub-air outlets 22, and the exhaust fans cooperate with the fan 6 of the air conditioning system to ensure the mutual independence of the air supply flow paths between each group of upper air duct sub-air outlets 12 and lower air duct sub-air outlets 22, that is, there is no impact or very little impact.

[0076] In some alternative implementation manners, there are two upper air ducts 1, including a left upper air duct and a right upper air duct which are arranged left and right; there are two lower air ducts 2, including a left lower air duct and a right lower air duct which are arranged left and right. Further, the upper air duct sub-air outlet 12 of the left upper air duct corresponds to the lower air duct sub-air outlet 22 of the left lower air duct, and the upper air duct sub-air outlet 12 of the right upper air duct corresponds to the lower air duct sub-air outlet 22 of the right lower air duct. This arrangement further ensures that the air flow paths formed between each group of upper air duct sub-air outlets 12 and lower air duct sub-air outlets 22 are independent of each other, that is, the influence is small or negligible.

[0077] In some implementation manners, to meet the freshness of the air inside the vehicle, when the vehicle interior circulation is not required, the automotive air conditioning system can also introduce fresh air. Specifically, the automotive air conditioning system further includes a fresh air component and an exhaust component. The fresh air component is connected to the fan component and is used to send fresh air into the vehicle interior through the fan component; the exhaust component is connected to the upper air duct 1 and / or the lower air duct 2 and is used to discharge the air inside the vehicle to the outside of the vehicle through the upper air duct or the lower air duct.

[0078] Further, the fresh air component includes a fresh air duct and a fresh air damper. The inlet of the fresh air duct communicates with the outside of the vehicle, and the outlet of the fresh air duct communicates with the inlet of the fan component; the fresh air damper is used to close the fresh air duct when fresh air is not required and open the fresh air duct when fresh air needs to be introduced. In addition, to prevent dust, viruses, harmful gases, etc. from being mixed in the outside air, the fresh air component is also provided with a fresh air treatment module. The fresh air treatment module is arranged in the fresh air duct or between the outlet of the fresh air duct and the inlet of the fan component. The fresh air treatment module can filter, sterilize, etc. the fresh air sent into the fan component through the fresh air duct to ensure the health of the personnel inside the vehicle equipped with this air conditioning system.

[0079] The exhaust component includes an exhaust duct and an exhaust damper, where: the exhaust duct communicates with the upper air duct 1 and / or the lower air duct 2, and the exhaust damper is used to open or close the exhaust duct. Further, a sterilization module can also be arranged in the exhaust component to treat the air inside the vehicle before discharging it to the outside of the vehicle to prevent harm to the personnel outside the vehicle.

[0080] The automotive air conditioning system adopts an upper and lower double air duct layout structure, which realizes that after the air is collected and returned through the upper air duct or the lower air duct, it is discharged to the air treatment module 3 inside the air conditioner. After sterilization and disinfection, it enters the condensation evaporator through the centrifugal fan of the vehicle, and then circulates back to the lower air duct or the upper air duct for air outlet again, so that the air inside the vehicle remains sterile and non-toxic, avoiding infection. The reasonable air duct design realizes the free switching between the upper air duct for air outlet and the lower air duct for air return and the lower air duct for air outlet and the upper air duct for air return. Combined with the upper air duct for air outlet and the lower air duct for air return when the air conditioner is cooling, and the lower air duct for air outlet and the upper air duct for air return when heating.

[0081] Embodiment 2

[0082] In this embodiment, an automobile is provided, which adopts any one of the automobile air-conditioning systems in the above-mentioned Embodiment 1. Among them, the upper air duct is arranged at the top of the automobile, and the upper air duct sub-air outlet 12 is located above the seats in the automobile; correspondingly, the lower air duct is arranged at the bottom of the automobile, and the lower air duct sub-air outlet 22 is located below the seats in the automobile.

[0083] Preferably, the automobile air-conditioning system adopts a rear-mounted type, wherein: the fan assembly is located at the rear of the automobile, the upper air duct extends from the rear of the automobile to the front of the automobile, and the lower air duct extends from the rear of the automobile to the front of the automobile. Adopting the rear-mounted automobile air-conditioning layout scheme, both the upper air duct main air outlet 11 and the lower air duct main air outlet 21 are at the rear of the automobile. When one of them is used as the air inlet, its position is behind the rear row seats of the bus. The overall air flow enters and exits through the upper air duct or the lower air duct in the vehicle to complete the in-vehicle circulation.

[0084] To further illustrate the automobile adopting the automobile air-conditioning system in Embodiment 1, taking a bus as an example, combined with Figure 1-8 as shown.

[0085] The air conditioner in this bus can effectively reduce the cross-infection coefficient among passengers in public transportation, especially in the case where virus infection may occur. The bus adopts an upper and lower double air duct structure (upper air duct and lower air duct) and uses the differential pressure theory for air duct structure design to ensure that after the air is evaporated and condensed, it flows through the passengers at the seats through the air outlet of the air duct (upper air duct sub-air outlet or lower air duct sub-air outlet), and then immediately enters the sterilization module (air treatment module) through the other air duct. After sterilization, the air is evaporated and condensed again to achieve in-vehicle gas sterilization in-circulation.

[0086] When the working mode of the automobile air-conditioning system is heating, the lower air duct is used for air outlet and the upper air duct is used for air return; when refrigerating, the upper air duct is used for air outlet and the lower air duct is used for air return. At other times, it can also be switched back to double air ducts for simultaneous air outlet and single air duct for air outlet. Among them: when the double air ducts are for simultaneous air outlet, the first air door 71 rotates to the first port 41 of the first three-way structure, and at the same time, the second air door 72 rotates to the second port 52 of the second three-way structure.

[0087] When refrigerating, the air flow direction inside the air conditioner is as shown in Figure 2 and Figure 6-8As shown, the air flow flows out from the upper air duct outlet 12 after passing through the condensation evaporator, and then flows through the rear of the passengers (without spreading to the surrounding passengers) and directly flows into the lower air duct through the return air duct (lower air duct outlet), and then flows into the second three-way structure 5 through the lower air duct. In the air conditioning system, the first air damper 71 and the second air damper 72 have achieved the connection selection of the air ducts according to the preset switching method. The return air duct connecting to the upper air duct (the first port of the first three-way structure) is closed, and the return air duct of the lower air duct (the second port of the second three-way structure) is opened. The return air flow passes through the second three-way structure 5 and the first three-way structure 4 and then flows to the sterilization module (air treatment module) and then enters the centrifugal fan of the bus. Thus, one internal circulation is completed.

[0088] During heating, the air flow direction is to blow out through the lower air duct after condensation evaporation and return air through the upper air duct. At this time, the return air duct of the upper air duct (the first port of the first three-way structure) is opened, and the return air duct at the lower air duct (the second port of the second three-way structure) is closed to complete.

[0089] As Figure 5 shown, the sterilization and disinfection module (air treatment module) is located in the upper part of the bus air conditioner. Whether the air in the vehicle returns through the upper air duct or the lower air duct, it has to flow out from the same return air outlet and flow through the sterilization module. Then the sterile air enters the next vehicle internal circulation to achieve sterile and non-toxic air in the vehicle.

[0090] The centrifugal fan of the air conditioner generates a pressure difference in the corresponding air ducts. For example, when the return air duct of the upper air duct is closed, the upper air duct blows out air. At this time, a pressure difference is generated between the upper air duct outlet 12 and the lower air duct outlet 22, so that the air flow is as Figure 6 shown, and it directly blows out from the upper air duct and then quickly returns to the sterilization module through the lower air duct after flowing into the passengers' seats for sterilization.

[0091] The above specifically shows and describes the exemplary embodiments of the present disclosure. It should be understood that the present disclosure is not limited to the detailed structures, setting methods or implementation methods described here; on the contrary, the present disclosure is intended to cover various modifications and equivalent settings included within the spirit and scope of the appended claims.
