Device and method for carrying out decontamination measures, method for preparing decontamination measures and method for monitoring decontamination measures
View Patent ↗A method for preparing decontamination measures within a room located in a building and used by people includes a planning acquisition step. Therein, a plurality of regions of use within the room are identified, and for each region an expected use intensity is determined based on previously determined parameters. In a subsequent planning implementation step, for each region of use, proceeding from the expected use intensity, a suction means assigned to said region of use and having an associated supply air volume flow is specified. In a method by carrying out the decontamination measures, while the decontamination measures are being carried out, operation of individual suction means is adjusted to an actual use of the assigned region of use by people, and a suction volume flow suctioned by the suction means in question is specified, between a minimum value specified for the suction means in question, and a maximum value.
1 . A device for carrying out decontamination measures within a room ( 1 ) located in a building and used by people ( 19 ), comprising:
a suction means ( 20 , 21 , 32 ) that is assigned to a region of use ( 7 , 9 ), the region of use ( 7 , 9 ) having at least two use cells ( 42 ) within the region of use ( 7 , 9 ); and
an air supply means ( 28 ),
wherein the suction means ( 20 , 21 , 32 ) comprises a suction opening ( 34 ) which is arranged in a flow guidance plate ( 33 ) which surrounds the suction opening ( 34 ) and is arranged above a specifiable breathable air altitude ( 31 ),
wherein the air supply means ( 28 ) comprises a strip-shaped air supply nozzle ( 38 ) which is arranged between the at least two use cells ( 42 ) and under the suction opening ( 34 ),
wherein the nozzle generates a strip-shaped supply airstream ( 41 ) such that, when the device is operated as intended, an initially strip-shaped supply airstream ( 41 ) is converted into a suction flow ( 30 ) which conveys air out of the breathable air altitude ( 31 ) to the suction means ( 20 ) and suctions it through the suction opening ( 34 ),
wherein the flow guidance plate ( 33 ) comprises, at least in portions, a suction gap ( 46 ) along a peripheral edge ( 45 ) thereof, on a side thereof directed towards the air supply means ( 28 ),
wherein an exhaust air flow flows along a flow guidance surface ( 44 ) of the flow guidance plate ( 33 ) in the direction of the suction opening ( 34 ), and
wherein the suction gap generates a Coanda effect, thereby guiding the exhaust air flow along on the flow guidance surface ( 44 ).
2 . The device according to claim 1 ,
wherein the flow guidance plate ( 33 ) comprises a convex or planar flow guidance surface ( 44 ) facing away from the air supply means ( 28 ).
3 . The device according to claim 1 , further comprising a room air suction means ( 49 ) which comprises room air suction openings ( 51 ) above the flow guidance plate ( 33 ).
4 . The device according to claim 3 ,
wherein the room air suction means ( 49 ) comprises at least one room air suction opening ( 51 ) in a suction channel ( 35 ) that leads into the suction opening ( 34 ).
5 . A device for carrying out decontamination measures within a room ( 1 ) located in a building and used by people ( 19 ), comprising:
a suction means ( 20 , 21 , 32 ) that is assigned to a region of use ( 7 , 9 ), the region of use ( 7 , 9 ) having at least two use cells ( 42 ) within the region of use ( 7 , 9 ); and
an air supply means ( 28 ),
wherein the suction means ( 20 , 21 , 32 ) comprises a suction opening ( 34 ) which is arranged in a flow guidance plate ( 33 ) which surrounds the suction opening ( 34 ) and is arranged above a specifiable breathable air altitude ( 31 ),
wherein the air supply means ( 28 ) comprises a strip-shaped air supply nozzle ( 38 ) which is arranged between the at least two use cells ( 42 ) and under the suction opening ( 34 ),
wherein the nozzle generates a strip-shaped supply airstream ( 41 ) such that, when the device is operated as intended, an initially strip-shaped supply airstream ( 41 ) is converted into a suction flow ( 30 ) which conveys air out of the breathable air altitude ( 31 ) to the suction means ( 20 ) and suctions it through the suction opening ( 34 ), and
wherein the device comprises at least one diffuser tube ( 43 ) which comprises a plurality of diffuser openings that are spaced apart in an axial direction and are oriented differently in peripheral directions, through which openings fresh air can be supplied to the region of use.
6 . The device according to claim 5 ,
wherein the flow guidance plate ( 33 ) comprises, at least in portions, a suction gap ( 46 ) along a peripheral edge ( 45 ) thereof, on a side thereof directed towards the air supply means ( 28 ),
wherein an exhaust air flow flows along a flow guidance surface ( 44 ) of the flow guidance plate ( 33 ) in the direction of the suction opening ( 34 ), and
wherein the suction gap generates a Coandă effect, thereby guiding the exhaust air flow along on the flow guidance surface ( 44 ).
7 . The device according to claim 5 ,
wherein the diffuser tube ( 43 ) is arranged at a distance from the air supply means ( 28 ) and the suction means ( 32 ), along a room edge ( 54 ) of the room ( 1 ).
8 . The device according to claim 5 ,
wherein the at least one diffuser tube ( 43 ) is arranged laterally beside the flow guidance plate ( 33 ) or above the flow guidance plate ( 33 ).
9 . A device for carrying out decontamination measures within a room ( 1 ) located in a building and used by people ( 19 ), comprising:
a suction means ( 20 , 21 , 32 ) that is assigned to a region of use ( 7 , 9 ), the region of use ( 7 , 9 ) having at least two use cells ( 42 ) within the region of use ( 7 , 9 ); and
an air supply means ( 28 ),
wherein the suction means ( 20 , 21 , 32 ) comprises a suction opening ( 34 ) which is arranged in a flow guidance plate ( 33 ) which surrounds the suction opening ( 34 ) and is arranged above a specifiable breathable air altitude ( 31 ),
wherein the air supply means ( 28 ) comprises a strip-shaped air supply nozzle ( 38 ) which is arranged between the at least two use cells ( 42 ) and under the suction opening ( 34 ),
