Device for Ventilating a Space and Corresponding Method

Abstract

A device and corresponding method for ventilating a space is provided. The device includes an air conditioning system that is adapted for conditioning recirculated and/or fresh air to be used for the ventilation of the space. The device also includes at least one air treatment means adapted for exposing the recirculated and/or fresh air to one or more of UVC, ozone and/or atomized detergents. Relative to an air stream, the air treatment means is positioned prior to the air conditioning system receiving the recirculated and/or fresh air, and/or prior to the air conditioning system releasing the air into the space.

Claims

1. A device for ventilating a space, comprising: an air conditioning system adapted and configured for conditioning recirculated and/or fresh air to be used for the ventilation of the space, and at least one air treatment means adapted and configured for exposing the recirculated and/or fresh air to one or more of UVC, ozone and/or atomized detergents, relative to an air stream flowing to the air treatment means, the air treatment means being positioned prior to the air conditioning system receiving the recirculated and/or fresh air and/or prior to the air conditioning system releasing the air into the space.

2. A method for ventilating a space with an air conditioning system, the method comprising the steps of: extracting soiled air in the space by a first negative pressure acting on the soiled air; feeding the extracted soiled air to at least one filter to be cleaned with the at least one filter; exposing the filter to sterilization means to be sterilized by the sterilization means; and treating the air cleaned by the filter with at least one air treatment means, wherein the air treatment means treats the air prior to the air conditioning system receiving the air and/or after the air conditioning system releases the air into the space.

3. The method of claim 2 wherein the step of exposing the filter to sterilization means includes exposing the filter to one or more of UVC, ozone and/or atomized detergents.

4. The method of claim 2 further comprising pulling recirculated and/or fresh air into the space by generating a second negative pressure.

5. The method of claim 4 further comprising forming within the space a first layer of soiled air and a second layer of recirculated and/or fresh air.

Description

DESCRIPTION OF DRAWINGS

[0067] The invention will be explained in more detail below with reference to the exemplary embodiments illustrated in the drawings, in which:

[0068] FIG. 1 shows a side view of a room, preferably a room of building, ventilated according to the method of the invention.

DETAILED DESCRIPTION

[0069] FIG. 1 shows a room 1, comprising walls 2.

[0070] These walls 2 are arranged between the ceiling 3 and a floor 4 of the building 7.

[0071] In the side view, the building 7 comprises an entrance 5 to the room 1 within the building 7.

[0072] In the rear of room 1 the building 7 includes a service room 8.

[0073] In the FIG. 1 the room 1 comprises a recessed ceiling 9 having numerous openings 10 to supply recirculated and/or fresh air 11 into the room 1.

[0074] In the service room 8 one can see an air conditioning system 12 comprising an air pump 13.

[0075] The openings 10 arranged in the recessed ceiling 9 of the room 1 are connected with the air conditioning system 12 via supply ducts 14.

[0076] The supply ducts 14 supply recirculated and/or fresh air 11 to the openings 10 in the recessed ceiling 9 to be supplied into the room 1.

[0077] The fresh air 11 supplied into the room 1 through the opening 10 of the recessed ceiling 9 form a layer 15 of recirculated and/or fresh air 11.

[0078] The layer 15 of recirculated and/or fresh air 11 floats on top of a layer of soiled air 16.

[0079] A negative pressure 17 acting on ports 18 in the floor 4 leads to an extraction 19 of soiled air 16 through the ports 18 arranged in the floor 4 of the room 1.

[0080] The extraction 19 of the layer of soiled air 16 through the ports 18 generates a second negative pressure 20 pulling recirculated and/or fresh air 11 from the openings 10 into the room 1 to form the layer 15 of the recirculated and/or fresh air 11.

[0081] Within the room 1 of the building 7 there is a laminar flow system with a first negative pressure 17 acting on the layer of soiled air 16 and extracting the soiled air 16 through the ports 18 arranged in the floor 4.

[0082] On top of the layer 16 of soiled air of the laminar flow system there is the layer 15 of recirculated and/or fresh air 11.

[0083] The extraction of layer 16 of soiled air through the ports 18 generates a second negative pressure 20 arranged between the layer 15 of recirculated and/or fresh air 11 and the recessed ceiling 9.

[0084] The first negative pressure 17 acts on the layer 16 of soiled air and the second negative pressure 20 acts on the openings 10, providing recirculated and/or fresh air 11 into the room 1, forming a layer 15 of recirculated and/or fresh air 11.

[0085] The more soiled air 16 is extracted from the room 1 through the ports 18 of the floor 4, the more recirculated and/or fresh air 11 is resupplied into the room 1 through openings 10.

[0086] Extraction ducts 22 are arranged to feed soiled air of the layer of soiled air 16, extracted through the ports 18 to a filter 21 which comprise filtering means. A filter 21a may be provided in the wall separating the room 1 from the service room 8.

[0087] The filtering means of the filter 21 are exposed to sterilization (not shown) means, after the filter has cleaned the soiled air.

[0088] A treatment means 23 is also arranged in the service room 8 for treating the air cleaned in or by the filter 21.

[0089] A sterilization means 24 is also arranged in the service room 8 for sterilizing the filter 21.
