Definitions
- the present invention relates to a ventilation system of the passenger compartment of a public transport vehicle. It also relates to a ground public transport vehicle, bus or tram-bus type, equipped with such a ventilation system.
- the field of the invention is the field of land vehicles, in particular electric vehicles, public transport, bus, coach or tram-bus.
- the interior of a public transport vehicle, bus or tram-bus, is intended to accommodate a large number of people. Therefore, the interior of a vehicle must be large.
- the transit vehicle must be equipped with systems to meet various needs within the cabin, such as heating, lighting, ventilation, etc. These systems must be dimensioned sufficiently large to meet the needs associated with a large passenger compartment.
- the ventilation system associated with the passenger compartment of a public transport vehicle must be sized sufficiently large to meet the need for ventilation of said passenger compartment.
- the aeration systems generally comprise a large ventilation block, deposited on the roof of the vehicle, which feeds a ventilation circuit passing through the passenger compartment.
- a ventilation system is bulky.
- a bulky aeration block placed on the roof of a vehicle degrades its balance, increase its consumption, because of the resistance to air that can constitute such a block, and limits the possibility of circulation of such a vehicle on certain roads, because of the additional height it presents.
- these current aeration systems are energy hungry.
- the air vents are located vertically from the vent block to the outside. Thus, the air is taken outside by the air vents is blown into the cabin at the same place, which does not allow effective ventilation.
- An object of the present invention is to overcome these disadvantages.
- Another object of the invention is to provide a ventilation system for public transport vehicle less bulky and providing less damage to the performance of the vehicle in terms of handling, consumption and height.
- Yet another object of the invention is to provide an aeration system for a better distribution of air in the passenger compartment of the vehicle.
- a ventilation system of the passenger compartment of a public transport vehicle comprising:
- At least one air distribution circuit connecting said openings to one another.
- the system according to the invention proposes to provide several air intake openings and several air introduction openings in the passenger compartment. Therefore, it is not necessary to provide one or more bulky aeration block (s), as in current vehicles. As a result, the performance of the transit vehicle, in terms of handling, fuel consumption and maximum height, is less, if at all, degraded with the aeration system according to the invention.
- the system comprises a plurality of air intake openings provided on the upper wall of the vehicle for capturing the outside air which is then distributed in the passenger compartment with at least one distribution circuit. Therefore, the distribution circuit connecting a pick-up opening to an introductory opening, has a shorter length, compared to current aeration systems.
- the ventilation system according to the invention is less energy-intensive, and has less pressure losses, while achieving a better distribution of air in the passenger compartment of the vehicle.
- At least one air intake opening may be provided with at least one device for driving the outside air to a distribution circuit, such as a fan.
- the rotational speed of the fan may be adjustable so that the aeration rate, and in particular the air flow, can be adjusted.
- At least one air intake opening may be provided with two external air entrainment devices, positioned head-to-tail, so as to return the outside air captured. in two substantially opposite directions to two corresponding distribution circuits.
- This also makes it possible to increase the possibility of adjusting the ventilation achieved by the system according to the invention, in terms of flow rate and zones. For example, it is possible to adjust the aeration performed in one zone independently of the other zones.
- at least one, in particular each, air entrainment device can be associated with a distribution circuit, independent of other distribution circuits.
- each of said drive devices can be associated with a distribution circuit independent of the distribution circuit associated with the other of said drive devices.
- at least one air intake opening may be provided with an air treatment device.
- An air treatment device may comprise an air conditioner or a heat pump, and more generally any device modifying the temperature of the outside air captured.
- an air handler may include means for filtering air.
- At least one pick-up opening may be connected to at least one, in particular several, distribution circuit (s) extending in the longitudinal direction of the vehicle.
- each of said drive devices can be associated with a distribution circuit extending in the longitudinal direction of the vehicle.
- At least one capture opening may be connected to two distribution circuits extending in the longitudinal direction of the vehicle, substantially parallel to each other.
- each of the two circuits parallel can be associated, independently, with one of said driving devices.
- two capture openings can be connected to two different distribution circuits, succeeding in the longitudinal direction of the vehicle, in opposite directions.
- Such a characteristic allows a greater freedom in the design of the ventilation system according to the invention, in particular in the positioning of the capture openings, while limiting the length of the distribution circuits.
- the system according to the invention may comprise three air intake openings:
- a first air intake opening located in the front part
- central opening located in the central part
- the central capture opening may be closer to the rear capture opening compared to the front capture opening.
- central capture opening and the front capture opening can be connected to longitudinal circuits of opposite directions.
- the front capture opening can be connected to at least one longitudinal circuit extending from the front to the rear and the central capture opening can be connected to at least one longitudinal circuit extending from the rear forward.
- At least one circuit can be connected to at least two insertion openings in series, so that the air captured at the same capture opening is distributed serials openings.
- At least one circuit is connected to at least two insertion openings in parallel, so that the air captured at the same capture opening is distributed to said openings in parallel.
- a public transport vehicle comprising an aeration system according to the invention.
- the system according to the invention may preferably be arranged at an upper wall of said vehicle.
- the vehicle according to the invention is an electric vehicle.
- Such an electric vehicle can include:
- the public transport vehicle may be a bus, or a coach, or a tram-bus, particularly electric.
- trim-bus is meant a terrestrial electric public transport vehicle mounted on wheels and which is recharged at each station, so as not to require heavy rail-type infrastructures, catenaries, on the road. Such an electric vehicle is recharged at each station by means of load elements of the station and a connector connecting said vehicle to said station.
