[0001] The present invention describes an air renewal system in a public transport vehicle and a system assembly process. Specifically, the present invention comprises an air renewal system comprising an air renewal device on the lower floor and an air renewal device on the upper floor of the vehicle, which allow for the renewal of the quality of the air circulating both in the lounge on the floor both in the lower and in the vehicle's upper floor lounge by capturing external air through ducts positioned in specific regions of the vehicle's bodywork and insufflating renewed external air into said lounges. The present invention is located in the fields of mechanical engineering and electrical engineering, focused on the area of thermal solutions and air renewal applied in public transport vehicles.
Antecedentes da Invenção Background of the Invention
[0002] Os veículos de transporte coletivo de dois andares atuais, conhecidos comercialmente como ônibus Double Decker ou ônibus DD, possuem sistemas de renovação de ar direcionados para apenas no piso superior do veículo, de modo que a renovação do ar que circula internamente é apenas realizada no piso superior, sendo inexistente a renovação de ar no piso inferior. [0002] Current double-decker public transport vehicles, known commercially as Double Decker buses or DD buses, have air renewal systems directed to only the upper floor of the vehicle, so that the renewal of the air that circulates internally is only carried out on the upper floor, with non-existent air renewal on the lower floor.
[0003] Nesse sentido, os sistemas de renovação de ar do piso superior de ônibus Double Decker atuais são acoplados e dispostos em frente ao evaporador do sistema de ar-condicionado, de modo que o sistema de renovação de ar ocupa espaço no porta-pacotes do veículo, reduzindo a capacidade de armazenamento de bagagem no porta-pacotes do piso superior. [0003] In this sense, the air renewal systems on the upper deck of current Double Decker buses are coupled and arranged in front of the air conditioning system evaporator, so that the air renewal system takes up space in the luggage carrier of the vehicle, reducing the ability to Luggage storage on top floor luggage rack.
[0004] Ainda, a renovação de ar no piso superior dos ônibus Double Decker atuais é feita coletando-se o ar externo através da lateral da carroceria do veículo e insuflando o ar externo lateralmente no sistema de ar-condicionado do veículo. [0004] Also, the renewal of air on the upper floor of the current Double Decker buses is done by collecting the outside air through the side of the vehicle bodywork and blowing the outside air laterally into the vehicle's air conditioning system.
[0005] Desta forma, os sistemas de renovação de ar aplicados em ônibus de dois andares atuais possuem diversas limitações estruturais e de posicionamento/acoplamento na carroceria do veículo que resultam em deficiências na aplicação do sistema nos dois andares do veículo, bem como na aplicação do sistema especificamente no piso superior, que ocupa espaço no porta-pacotes, reduzindo a capacidade de armazenamento de bagagens dos passageiros. [0005] In this way, the air renewal systems applied in current double-decker buses have several structural limitations and positioning/coupling in the vehicle bodywork that result in deficiencies in the application of the system in the two-deckers of the vehicle, as well as in the application of the system specifically on the upper floor, which takes up space in the luggage rack, reducing the capacity for storing passengers' luggage.
[0006] Ademais, em vista dos problemas supracitados, a renovação da qualidade do ar que circula no salão do piso superior e inferior é limitada, o que pode acarretar uma desinfecção inadequada do ar que circula no interior dos dois pisos do veículo. [0006] Furthermore, in view of the aforementioned problems, the renewal of the quality of the air circulating in the lounge on the upper and lower floors is limited, which may lead to inadequate disinfection of the air circulating inside the two floors of the vehicle.

Exemplo 1 - Sistema de renovação de ar para piso superior e inferior de ônibus Double-Decker Example 1 - Air renewal system for upper and lower floors of a Double-Decker bus
[0082] Os exemplos aqui mostrados têm o intuito somente de exemplificar uma das inúmeras maneiras de se realizar a invenção, contudo sem limitar, o escopo da mesma. [0082] The examples shown here are intended only to exemplify one of the many ways to carry out the invention, but without limiting its scope.
[0083] Neste exemplo, foi desenvolvido um sistema de renovação de ar para ônibus de dois andares (Double-Decker) que permite a renovação da qualidade do ar que circula tanto no salão do piso inferior quanto no salão do piso superior do veículo a partir da captação do ar externo e insuflamento para dentro dos referidos salões. [0083] In this example, an air renewal system for double-decker buses (Double-Decker) was developed, which allows the renewal of the quality of the air that circulates both in the lounge on the lower floor and in the lounge on the upper floor of the vehicle from capturing external air and supplying it into the aforementioned halls.
[0084] O sistema compreende um dispositivo de renovação de ar do piso inferior e um dispositivo de renovação de ar do piso superior que são acionados simultaneamente através do acionamento de um motor que aspira o ar externo, e operam de maneira independente um ao outro, de forma que o volume de ar externo captado pelo dispositivo de renovação de ar do piso inferior é direcionado somente ao piso inferior do ônibus e o volume de ar externo captado pelo dispositivo de renovação de ar do piso superior é direcionado somente ao piso superior do ônibus. [0084] The system comprises a lower floor air renewal device and an upper floor air renewal device that are activated simultaneously by activating a motor that sucks the outside air, and operate independently of each other, so that the volume of external air captured by the air renewal device on the lower floor is directed only to the lower floor of the bus and the volume of external air captured by the air renewal device on the upper floor is directed only to the upper floor of the bus .
[0085] Cada dispositivo de renovação de ar - inferior e superior - possui um conjunto renovador (3, 7) de ar , ilustrados nas figuras 14 e 15, sendo dotados de quatro entradas de ar externo (20), duas posicionadas do lado direito e duas posicionadas do lado esquerdo do conjunto renovador (3, 7). Ainda, cada duas entradas de ar externo (20) possui um defletor (21) (chicana interna) associado a uma manta filtrante (22), de modo que o defletor (21 ) direciona a circulação de ar externo e a manta filtrante (22) filtra o ar e possíveis líquidos que possam entrar pelos dutos de captação de ar (5, 8). [0085] Each air renewal device - lower and upper - has an air renewer assembly (3, 7), shown in figures 14 and 15, with four external air inlets (20), two positioned on the right side and two positioned on the left side of the renovator set (3, 7). Also, each two external air inlets (20) has a deflector (21) (internal baffle) associated to a filtering blanket (22), so that the deflector (21) directs the circulation of external air and the filtering blanket (22) filters the air and possible liquids that may enter through the air intake ducts (5, 8).
[0086] Ainda, o conjunto renovador (3, 7) possui um motor insuflador (24) que insufla o ar externo filtrado e renovado pela manta filtrante (22) para duas saídas de ar filtrado (23) que direcionam o ar para os sistemas de ar condicionado do veículo do piso superior e inferior (10, 11) através dos dutos (1 ) do piso inferior e mangueiras no piso superior. [0086] Also, the renewer set (3, 7) has a blower motor (24) that blows the external air filtered and renewed by the filtering blanket (22) to two filtered air outlets (23) that direct the air to the systems air conditioning of the vehicle on the upper and lower floors (10, 11) through the ducts (1) on the lower floor and hoses on the upper floor.
[0087] Os líquidos que possam adentrar pelos dutos de captação de ar (5, 8) em um dia de chuva, por exemplo, são direcionados para o interior e fundo dos conjuntos renovadores (3, 7) e canalizados para um dreno de líquidos (25), o qual é conectado com uma região de drenagem de líquidos (26) da carroceria do ônibus por meio de um canal (27). Desta forma, os líquidos que entram no conjunto renovador (3, 7) ficam retidos no interior do conjunto (3, 7) e são direcionados e eliminados para fora do sistema por gravidade através do dreno de líquidos (25) e do canal (27). A figura 14 mostra uma vista explodida que detalha e ilustra todos os componentes do conjunto renovador (3, 7) supracitados. [0087] Liquids that may enter the air collection ducts (5, 8) on a rainy day, for example, are directed to the interior and bottom of the renovating sets (3, 7) and channeled to a liquid drain (25), which is connected with a liquid drainage region (26) of the bus body through a channel (27). In this way, the liquids that enter the renewing set (3, 7) are retained inside the set (3, 7) and are directed and eliminated out of the system by gravity through the liquid drain (25) and the channel (27 ). Figure 14 shows an exploded view detailing and illustrating all the components of the aforementioned renovator set (3, 7).
[0088] Desta forma, o conjunto renovador (3, 7) desenvolvido é capaz de separar líquidos que possam ser aspirados de forma indesejada, evitando que seja direcionado aos salões de passageiros. A principal vantagem do conjunto renovador (3, 7) desenvolvido é que, desta forma, permite a utilização do sistema de renovação de ar mesmo em dias de chuva. [0088] In this way, the renovated set (3, 7) developed is capable of separating liquids that can be sucked in an unwanted way, preventing it from being directed to the passenger lounges. The main advantage of the renovated set (3, 7) developed is that, in this way, it allows the use of the air renewal system even on rainy days.
[0089] O dispositivo de renovação de ar do piso inferior é conforme ilustrado na figura 1 , e possui pelo menos um duto de captação de ar inferior (5) posicionado na região lateral traseira da carroceria do piso inferior do veículo, junto à janela (13) do piso inferior. Esse duto de captação de ar inferior (5) é conectado com um conjunto renovador inferior (3) por meio de mangueiras de ligação externa (4). [0089] The lower floor air renewal device is as shown in figure 1, and has at least one lower air intake duct (5) positioned in the rear lateral region of the bodywork of the lower floor of the vehicle, next to the window ( 13) on the lower floor. This lower air intake duct (5) is connected to a lower renewer set (3) by means of external connection hoses (4).
[0090] Ainda, o duto (5) possui uma tela metálica (6) associada na entrada do duto (5) que impede a entrada de partículas indesejadas, realizando a filtragem de partículas que podem afetar o funcionamento do dispositivo, como partículas de poeira, pedregulhos, etc. As figuras 2 e 3 mostram o posicionamento dos dutos (5) no lado direito e esquerdo, respectivamente, do veículo. [0090] Also, the duct (5) has a metallic screen (6) associated with the entrance of the duct (5) that prevents the entry of unwanted particles, filtering particles that can affect the operation of the device, such as dust particles, pebbles, etc. Figures 2 and 3 show the positioning of the ducts (5) on the right and left side, respectively, of the vehicle.
[0091] O conjunto renovador inferior (3) é encaixado dentro de uma caixa de proteção (2) que protege o conjunto renovador inferior (3) e as mangueiras de ligação externa (4). A figura 5 mostra a mangueira de ligação externa (4), que direciona o ar externo captado ao conjunto renovador inferior (3). A figura 9 mostra uma vista aproximada das mangueiras de ligação externa (4). [0091] The lower renewer set (3) is fitted inside a protection box (2) that protects the lower renewer set (3) and the external connection hoses (4). Figure 5 shows the external connection hose (4), which directs the external air captured to the lower renewer assembly (3). Figure 9 shows a close-up view of the external connection hoses (4).
[0092] Para conectar o conjunto renovador inferior (3) ao sistema de ar- condicionado (11) do piso inferior, tem-se um duto de ligação renovador-AC (1) com geometria que se encaixa entre o conjunto renovador inferior (3) e o sistema do ar-condicionado (11). Assim, o ar recebido no sistema de ar-condicionado (11) é distribuído ao longo do salão do piso inferior do veículo através de dutos de distribuição (14), renovando o ar que circula no piso inferior. As figuras 6 e 7 mostram os dutos de ligação renovador-AC (1). [0092] To connect the lower renovator set (3) to the air conditioning system (11) on the lower floor, there is an AC-renovator connection duct (1) with a geometry that fits between the lower renovator set (3 ) and the air conditioning system (11). Thus, the air received in the air-conditioning system (11) is distributed throughout the vehicle's lower floor lounge through distribution ducts (14), renewing the air that circulates on the lower floor. Figures 6 and 7 show the renovator-AC connection ducts (1).
[0093] A figura 1 mostra uma vista explodida do dispositivo de renovação de ar do piso inferior, ilustrando o conjunto renovador inferior (3) que se associa a caixa de proteção (2) e à mangueira de ligação externa (4), os dutos de ligação renovador-AC (1) que conectam o conjunto renovador inferior (3) ao evaporador do ar-condicionado (11) do piso inferior, e dutos de distribuição de ar renovado (14) que direcionam o ar renovado para o piso inferior do veículo. [0093] Figure 1 shows an exploded view of the lower floor air renewal device, illustrating the lower renewer set (3) that is associated with the protection box (2) and the external connection hose (4), the ducts renovator-AC connections (1) that connect the lower renovator set (3) to the air conditioning evaporator (11) on the lower floor, and renewed air distribution ducts (14) that direct the renewed air to the lower floor of the vehicle.
[0094] A figura 4 mostra o conjunto renovador inferior (3) associado ao evaporador do ar-condicionado (11) do piso inferior por meio do duto de ligação renovador-AC (1). [0094] Figure 4 shows the lower renovator set (3) associated with the air conditioning evaporator (11) on the lower floor through the renovator-AC connection duct (1).
[0095] A figura 8 mostra o conjunto renovador inferior (3) associado à caixa de proteção (2), que por sua vez está conectada ao evaporador do ar- condicionado (11) do piso inferior. [0095] Figure 8 shows the lower renovation set (3) associated with the protection box (2), which in turn is connected to the air conditioning evaporator (11) on the lower floor.
[0096] O dispositivo de renovação de ar do piso superior é conforme ilustrado na figura 10, e possui um duto de captação de ar superior (8) associado na região do teto da carroceria, junto à curvatura de acabamento da parte superior do veículo. O duto (8) o duto é conectado com um conjunto renovador superior (7) por meio de mangueiras (12). Assim, o ar externo entra nos dutos (8) e é direcionado ao conjunto renovador superior (7). As figuras 11 , 12 e 13 mostram o posicionamento dos dutos de captação de ar superior (8) na região superior da carroceria do veículo. [0096] The upper floor air renewal device complies with shown in Figure 10, and has an upper air collection duct (8) associated with the roof of the bodywork, next to the finishing curvature of the upper part of the vehicle. The duct (8) the duct is connected with an upper renovator assembly (7) by means of hoses (12). Thus, the external air enters the ducts (8) and is directed to the upper renewer assembly (7). Figures 11, 12 and 13 show the positioning of the upper air intake ducts (8) in the upper region of the vehicle bodywork.
[0097] Ainda, o conjunto renovador superior (7) é associado a uma estrutura de suporte (7.1) fixada na parte superior do veículo, e através de uma placa (7.2) que se associa a uma viga superior do veículo, de modo que o conjunto renovador (7) fica disposto lateralmente ao sistema do ar-condicionado (10) do piso superior, conforme ilustrado nas figuras 16 e 17. [0097] Also, the upper renovator assembly (7) is associated with a support structure (7.1) fixed to the upper part of the vehicle, and through a plate (7.2) that is associated with an upper beam of the vehicle, so that the renovator assembly (7) is arranged laterally to the air conditioning system (10) on the upper floor, as shown in figures 16 and 17.
[0098] A figura 10 mostra os dutos de captação de ar superior (8) posicionados na região superior do veículo, que captam o ar externo e direcionam para o conjunto renovador superior (7), ilustrando também o posicionamento do conjunto ventilador (7) ao lado do evaporador do ar- condicionado (10). [0098] Figure 10 shows the upper air intake ducts (8) positioned in the upper region of the vehicle, which capture external air and direct it to the upper renewer assembly (7), also illustrating the positioning of the fan assembly (7) next to the air conditioning evaporator (10).
[0099] Desta forma, o conjunto renovador (7) é posicionado lateralmente ao sistema do ar-condicionado em relação ao comprimento da parte superior do veículo. Essa disposição do renovador (7) ao lado do ar condicionado (10) proporciona melhor distribuição de peso e dos elementos que fazem parte do dispositivo de renovação de ar do piso superior, de modo a não ocupar espaço do porta-pacotes (15), liberando assim mais espaço para armazenamento de bagagens dos passageiros. A figura 13 mostra a localização dos dutos de captação de ar superior (8) na região superior externa do ônibus, de modo a não ocupar espaço do porta-pacotes (15) do veículo. [0099] In this way, the renovator assembly (7) is positioned laterally to the air conditioning system in relation to the length of the upper part of the vehicle. This arrangement of the renewer (7) next to the air conditioner (10) provides a better distribution of weight and of the elements that are part of the air renewal device on the upper floor, so as not to occupy space in the luggage rack (15), thus freeing up more space for passenger luggage storage. Figure 13 shows the location of the upper air intake ducts (8) in the upper outer region of the bus, so as not to occupy space in the vehicle's luggage rack (15).
[0100] Ainda, o conjunto renovador superior (7) é conectado ao sistema do ar-condicionado (10) do piso superior por meio de mangueiras. Desta forma, o ar externo renovado é insuflado pelo conjunto renovador superior (7) ao sistema do ar-condicionado (10) do piso superior, e distribuído ao longo do salão do piso superior do veículo. [0100] Also, the upper renovation set (7) is connected to the air conditioning system (10) on the upper floor through hoses. In this way, the renewed external air is blown by the upper renovator set (7) to the air conditioning system (10) on the upper floor, and distributed throughout the hall from the top floor of the vehicle.
[0101] Desta forma, o sistema de renovação de ar desenvolvido neste exemplo permite a renovação da qualidade do ar que circula tanto no salão do piso inferior quanto no salão do piso superior do veículo a partir da captação do ar externo por dutos (5, 8) posicionados na parte superior e na parte lateral do ônibus, e insuflamento do ar externo para dentro dos referidos salões, onde a disposição dos elementos de cada dispositivo de renovação de ar - piso inferior e piso superior - é otimizada para não ocupar espaço do bagageiro e do porta- pacotes (15) do piso superior, liberando assim mais espaço para armazenamento de bagagens dos passageiros. [0101] In this way, the air renewal system developed in this example allows the renewal of the quality of the air that circulates both in the lounge on the lower floor and in the lounge on the upper floor of the vehicle from the capture of external air by ducts (5, 8) positioned at the top and side of the bus, and external air supply into said lounges, where the arrangement of the elements of each air renewal device - lower floor and upper floor - is optimized so as not to occupy space in the luggage compartment and the luggage rack (15) on the upper floor, thus freeing up more space for storing passengers' luggage.
