Definitions

  • the present invention relates to an air-wall device for separating two areas of space adjoining one another at a door opening which can be closed by a door, with an airflow compressed into an airwall according to the preamble of claim 1.
  • Airwall equipment is well known per se (see, for example, DE-20205864-U). They serve to separate the climate or atmosphere and to prevent or at least reduce heat losses at building openings, in particular at open door openings, where due to frequent passage of people and / or vehicles mechanical separation devices can not or only insufficiently used.
  • air-wall systems relatively small amounts of air flow at very high pressure in a laminar or at least approximately laminar, planar core-jet flow at the building opening to be shielded, which causes a wall-shaped partitioning of the building opening against transverse air masses over the entire opening area.
  • the building openings or door openings can be arranged both inside the building and on an outer wall of the building.
  • air curtain systems are known in which blown relatively large amounts of air to be shielded building opening and usually previously heated to hold incoming cold air as possible, but at least so far to warm that the climate or temperature inside the building or the respective Space are changed as little as possible.
  • the amount of air blown out does not flow laminarly in a core air level, but comparatively turbulently.
  • DE 100 56 596 A1 has proposed an air curtain system of the type mentioned above which provides a customized air curtain as a function of the opening height of the door and the distance still to be bridged.
  • the arrangement of the air curtain on the closing edge associated with the closing area of the door can be achieved in each closed position of the door optimum position of the air curtain relative to each free opening area of the door opening and the efficiency of the air curtain can be increased accordingly with a simultaneous reduction in operating costs.
  • a disadvantage of this proposed solution is that the entire air curtain device is arranged as a compact complete installation on the closing area of the door.
  • the very high weight of such a complete installation can burden average sized gates in their static design in unacceptably high levels, so that the airflow system either not or can be used only with elaborate reinforcement constructions of existing gates.
  • the very high weight of the complete installation, in particular, the motors for opening and closing the door in terms of their drive performance clearly overburden, which can lead to damage and failure of the door drive and thus to significant adverse effects on operations and associated additional costs. To avoid such damage reinforcements of the gates and stronger door drives are therefore required, which is associated with additional material and installation costs and in particular with additional costs.
  • Both devices assume that two or more parallel juxtaposed air streams difficult to mix with each other. From this they deduce a good separation of the two gas atmospheres to be separated on both sides of the building opening.
  • Object of the present invention is therefore to provide a structurally simple, inexpensive to manufacture and easy to handle airwall device of the type mentioned, which offers improved shielding with low energy consumption, especially against odors and / or particles loaded atmospheres, and a permanently safe Guaranteed use at gates and no additional reinforcing measures regarding the carrying capacity of a conventional door or to increase the performance of the door drive requires.

  • the solution according to the invention is characterized by two significant advantages.
  • the first significant advantage is that not the complete airwall device must be arranged as a complete installation on the gate and carried along with the gate.
  • a highly effective air wall device is created at low operating costs, in particular also subsequently can be retrofitted to existing gates.
  • the gates can be designed in particular as a sliding, lifting, rolling or sectional doors.
  • the second major advantage of the solution according to the invention is that the advantages of a double Beerwandabschottung can be used without the disadvantages of turbulent air mixing in the space and the leakage of turbulent mixed air through an air wall through to the extent of the previously known air wall devices with parallel air walls occur. Mixing the two air walls can even be completely avoided at sufficiently large angles.

  • the air flow device is inexpensive to manufacture and easy to handle with a simple construction. It ensures an improved shielding of the two space areas at a building opening, not only with respect to different temperatures, with a low energy consumption. but especially if in the room area on one side of the building wall there is an atmosphere contaminated by odor and / or by particles, for example by dust or bacteria.
