Air curtain with a main air stream and an auxiliary air stream, and a device and method for producing the same

Abstract

Air curtain with an auxiliary stream, which is used to protect rooms against the impact of external factors (weather conditions, volatile substances, particulate solids, insects etc.), as well as to protect rooms against the outflow of internal air outside. The air exhausts form at least two separate air streams, the main stream is directed towards the construction hole at the limit of the room, while the auxiliary stream is directed into the room at an acute angle in relation to the plane of the construction hole. The main stream and the auxiliary stream do not cross each other.

1 . An air curtain comprising at least two separate air streams: a main air stream and an auxiliary air stream, wherein said main air stream is directed toward a construction hole at a limit of a room; said auxiliary air stream is directed at an acute angle in relation to the plane of the construction hole; and said main air stream and said auxiliary air stream do not cross each other. 
   
   
       2 . The air curtain of  claim 1 , wherein said main air stream and said auxiliary air stream are generated separately from each other. 
   
   
       3 . The air curtain of  claim 1 , wherein at least said main air stream or at least said auxiliary air stream have separate thermal parameters. 
   
   
       4 . The air curtain of  claim 1 , wherein said main air stream and said auxiliary air stream are filtered. 
   
   
       5 . The air curtain of  claim 1 , wherein said main air stream and said auxiliary air stream impinge on at least one directional element. 
   
   
       6 . The air curtain of  claim 1 , wherein said main air stream and said auxiliary air stream impinge on at least one moving directional element. 
   
   
       7 . A device for producing an air curtain, the air curtain comprising at least two separate air streams: a main air stream and an auxiliary air stream, the device comprising an air intake, at least a fan, and at least two air exhausts, wherein air entering said air intake and exiting said exhausts forms at least two separate air streams: a main air stream and an auxiliary air stream, wherein said main air stream is directed toward a construction hole at a limit of a room; said auxiliary air stream is directed at an acute angle in relation to the plane of the construction hole; and said main air stream and said auxiliary air stream do not cross each other. 
   
   
       8 . The device of  claim 7 , wherein said fan generates said main air stream and said auxiliary air stream separately from one another. 
   
   
       9 . The device of  claim 7  further comprising a heat exchanger, said heat exchanger setting thermal parameters of at least said main air stream or at least said auxiliary air stream. 
   
   
       10 . The device of  claim 7  further comprising an air filter that filters said air entering said air intake. 
   
   
       11 . The device of  claim 7  further comprising at least one directional element, wherein said directional element is directly connected to at least one said air exhaust and directs said main air stream and/or said auxiliary air stream. 
   
   
       12 . The device of  claim 7 , further comprising at least one moving directional element, wherein said moving directional element is directly connected to at least one said air exhaust, is mobile, and directs said main air stream and/or said auxiliary air stream. 
   
   
       13 . A method for producing the air curtain of  claim 1  using the device of  claim 7 , comprising passing electric current through said air fan whereby intaking air though said air intake and outputting air through said air exhausts and generating said main air stream and said auxiliary air stream. 
   
   
       14 . The method of  claim 13 , wherein said fan generates said main air stream and said auxiliary air stream separately from one another. 
   
   
       15 . The method of  claim 13  further comprising setting thermal parameters of at least said main air stream or at least said auxiliary air stream using a heat exchanger. 
   
   
       16 . The method of  claim 13  further comprising filtering said air entering said air intake and outputting filtered air as said main air stream and said auxiliary air stream. 
   
   
       17 . The method of  claim 13  further comprising directing said main air stream and/or said auxiliary air stream towards at least one directional element. 
   
   
       18 . The method of  claim 13 , further comprising directing said main air stream and/or said auxiliary air stream towards at least one moving directional element.
