Definitions

  • the present invention relates to a method for handling air when distributing air inside an elongated vehicle, the method comprising supply of air to a roof air duct inside the vehicle.
  • the invention also relates to a device for handling air when distributing air inside an elongated vehicle.
  • the known air-handling devices for elongated vehicles, e.g. buses, several radial blowers are included in the device.
  • the air leaves the blowers at relatively high speed and is either directly blown into the vehicle's roof air ducts or alternatively into a transfer duct between the rooftop unit and the roof air duct.
  • the known air-handling devices require 90° directional change of the air stream immediately adjacent to the blowers. In this area where the air stream changes direction the air speed drops locally and the static pressure is increased. In areas where supply air outlets to the passenger compartment are installed the static pressure is higher than in other locations. This results in a higher air speed supplied to the passenger compartment.
  • restriction means normally mounted by the vehicle manufacturers. This increases the overall cost of the system and decreases the performance of the device.
  • an air-handling device for buses is previously known.
  • the device comprises of inclined blowers that direct the air stream either to the front portion of the bus or to the rear portion of the bus.
  • the device according to DE 94 22 406 does not comprise of any means to locally adjust the direction of the air stream.
  • Blowers are connected to ducts that extend in the longitudinal direction of the bus. However, there are no means to direct the air when entering the longitudinal ducts. This means that a high pressure is created in the duct portions where the air from the fans enters the ducts. It is only the differential pressure in the ducts that will distribute air in the ducts.
  • a primary object of the present invention is to present a device of the type defined above, said device reducing local static pressure in the air-distributing means/the roof air duct.
  • a further object of the invention is to have a uniform climate in the entire vehicle.
  • Still a further object of the invention is to decrease the operation costs when running the device.
  • FIG. 1 shows a section through a portion of the roof of a vehicle that is equipped with an air-handling device according to the present invention
  • FIG. 2 shows a view of a number of units that are included in the device according to the present invention, the units being arranged in a row in the longitudinal direction of the vehicle;
  • FIG. 3 shows a perspective view of an air turn vane that constitutes an important component of the present invention.
  • FIGS. 1 and 2 an embodiment of the device according to the present invention is schematically disclosed.
  • the arrangement disclosed in FIGS. 1 and 2 is located along one side of the vehicle. Normally, a corresponding arrangement is also provided along the other side of the vehicle.
  • each unit 1 comprises an evaporator coil 3 and a heater coil 5 that is provided adjacent to the evaporator coil 3 .
  • the evaporator coil 3 is used for cooling the air that is handled by the device according to the present invention and the heater coil 5 is used for heating the air that is handled by the device according to the present invention.
  • Each unit 1 of the device according to the present invention also comprises a blower 7 having its outlet openings 10 directed towards means for active direction of the air, said means in the disclosed embodiment being turn vane units 9 adherent the blower 7 .
  • the blower is of radial type.
  • each blower 7 is equipped with two outlet openings 10 and consequently two turn vane units 9 are included in each unit 1 , said turn vane units 9 being located directly in front of an adherent outlet opening 10 .
  • a diffuser 8 is provided between the outlet openings 10 and an adherent turn vane unit 9 , said diffuser 8 having a widening cross-section towards the turn vane unit 9 .
  • FIG. 3 shows a perspective view of a turn vane unit 9 included in the device according to the present invention.
  • the turn vane unit 9 comprises a frame 11 and a number of parallel turn vanes 12 that are hingedly connected to the frame 11 , i.e. the turn vanes 12 being turnable relative to the frame 11 .
  • the turn vane unit 9 is preferably of conventional structural design, i.e. the turn vanes 12 are linked together in such a way that when one vane 12 is turned in a certain direction the rest of the vanes 12 are simultaneously turned in the same direction.
  • the turn vane unit 9 is equipped with operating means 13 in the shape of a small disk that is attached to one vane 12 .
  • the small disk 13 has an extension transverse to the extension of the vane 12 .
  • the adjustment of the vanes 12 is carried out manually by an operator that grips the small disk 13 and displaces the vanes 12 to a desired position. The adjustment could be continuous or in steps.
  • a roof air duct 15 extends in the longitudinal direction of the vehicle.
  • the turn vane units 9 are arranged on top of the roof air duct 15 , i.e. the turn vane units 9 are mounted in openings in the upper wall of the roof air duct 15 .
  • the roof air duct 15 has polygonal cross section.
  • the cross section of the roof air duct may vary in numerous ways.
  • the roof air duct 15 is equipped with numerous outlet apertures 16 that in the disclosed embodiment are in the shape of slots. The outlet air through the apertures 16 is indicated by the arrows P 1 and P 2 in FIG. 1 .
  • the device according to the present invention functions in the following way.
  • air is supplied to the device according to the present invention by an inlet opening 17 in the roof of the vehicle, i.e. the supplied air is coming from the passenger compartment.
  • the supplied air is indicated by the arrow P 3 in FIG. 1 .
  • the disclosed supplied air is only an example.
  • the supplied air could also be exterior air or a mixture of air from the passenger compartment and exterior air.
  • the supplied air P 3 bypasses the evaporator coil 3 and the heater coil 5 . If the evaporator coil 3 is active the bypassing air is cooled and if the heater coil 5 is active the bypassing air is heated.
  • the blowers 7 sucks the air from the adherent evaporator coil 3 /heater coil 5 and then the blowers 7 blow the air through the turn vane units 9 and into the roof air duct 15 .
  • the air In connection with the entry of the air into the roof air duct 15 the air is directed in the longitudinal direction of the roof air duct 15 , i.e. in the longitudinal direction of the vehicle.
  • the present invention relates to an active direction of the air that entries the roof air duct 15 .
  • FIG. 2 This is achieved by a certain tilting/turning of the vanes 12 of the turn vane unit 9 .
  • a certain amount of air is directed in one direction, i.e. in the direction of the arrows P 4
  • a certain amount of air is directed in the opposite direction, i.e. in the direction of the arrows P 5 .
  • the vanes 12 of the turn vane units 9 are turned in opposite directions in order to achieve air streams in opposite directions.
  • the orientation of the turn vanes 12 are carried out in connection with the mounting of the air-handling device in a vehicle. Normally, no further adjustment is needed but in case such an adjustment is deemed necessary, e.g. if conditions are changed, it could easily be carried out.
  • the orientation of the vanes 12 of the turn vane units 9 are operated manually.
  • the vanes 12 of the turn vane units 9 are adjustable as regards to their turning/tilting.
  • the vane units may comprise fixed vanes that have a certain set turning/tilting.
  • the air-handling device comprises an evaporator coil 3 and a heater coil 5 .
  • the evaporator coil 3 and/or the heater coil 5 could be omitted in case there is no need to cool or heat the handled air.
  • the air is moved by means of a blower 7 .
  • air moving means it is possible to use other types of fans or the like to move the air. Therefore, in certain of the appending claims the expression “air moving means” is used.
