Definitions
- the present invention relates to a method for mainly temporary ventilation of a room using a fan being arrang ⁇ ed to transfer air from the room through an existing opening in a wall limiting the room.
- the invention also relates to an apparatus for the execution of said method.
- a temporary, i.e. not permanent ventilation of a room here means e.g. ventilation of harmful solvents out from a room where paintwork is temporarily being undertaken.
- the object of the invention is to provide a method and an apparatus setting aside said problems as well as providing a controlled ventilation of a room through an open window or another opening in the room without appreciably influenc- ing adjacent rooms.
- a fan is used for transport of "the ventilating air.
- the ventilat ⁇ ing air On its way from the room the ventilat ⁇ ing air is brought to pass through a balloon placed in the opening, said balloon being arranged so that it is inflated and seals against the limiting edges of the opening and hereby separates the room from the space outside the same.
- From the fan is leading a flexible hose being connected to the side of the balloon facing the room.
- the balloon On the opposite side the balloon is preferably provided with exhaust holes
- OMPI being dimensioned in number and area so that the balloon is kept inflated to an extent sufficient to seal against the edges of the opening.
- FIG. 1 refers to a room, which is to be ventilat ⁇ ed, 2 to the ceiling of the room, 3 to its floor and 4 to a wall, preferably an outer wall being provided with a window 5 with a window frame 6.
- a fan stand 7 On the floor 3 is standing a fan stand 7 in which is mount ⁇ ed a cylindrical fan housing 8. In the lower part of the fan housing an axial fan 9 with a driving motor' 10 is pro ⁇ vided.
- the fan housing is ended at the bootom with a net 11. Also above the fan is a net 12, on top of which is an empty space 13.
- hose 14 is connected to the upper part of the fan housing, which hose leads to an inflatable balloon 15.
- the hose and the balloon could preferably be made from the same material — and also in one piece - e.g. from an essen ⁇ tially air tight textile, as so called spinnaker cloth.
- the hose and the balloon are stored in the space 13 when the apparatus is not in use.
- the balloon 15 is placed in the window opening 5 and by means of the fan 9 inflated so that it abuts the window * "-frame 6. From the balloon the ventilating air is led out through holes 16 in the outer wall of the balloon. Replace- ment air to the room 1 can be brought from adjacent rooms, stairways or the like.
- the apparatus has the same func ⁇ tion, as if a fan were mounted into a board sealing the window opening, i.e. exhaust of air can be effected through the window opening without letting ambient atmosphere into the room.
- the advantages offered by the apparat ⁇ us according to the invention in comparison with such an arrangement, as a simple manner of handling, flexibility and adaptability, the low location of the fan 9 and the placement of the fan stand 7 on the floor, results in that the relatively heavy, gaseous.solvents, which stay near • •- the floor, are directly caught by the fan and blown out through the hose 14 and the balloon 15.
