Ventilating system

Abstract

Disclosed is a ventilating system which is easily mounted by simplifying a coupling structure of a supply duct and an exhaust duct, the ventilating system including a cabinet mounted in a ceiling or a wall, for drawing in room air and discharging air into the room, a supply duct coupled with a first side of the cabinet, for guiding outdoor air to the cabinet, and an exhaust duct coupled with the first side of the cabinet, to which the supply duct is coupled, for guiding the room air into the room.

1 . A ventilating system comprising: 
 a cabinet mounted in a ceiling or a wall, for drawing in room air and discharging air into a room;    a supply duct coupled with a first side of the cabinet, for guiding outdoor air to the cabinet; and    an exhaust duct coupled with the first side of the cabinet to which the supply duct is coupled, for guiding the room air into the room.    
   
   
       2 . The ventilating system of  claim 1 , wherein the cabinet is mounted in the ceiling or the wall.  
   
   
       3 . The ventilating system of  claim 1 , wherein the cabinet comprises: 
 a first inlet for drawing in room air;    a second inlet formed on the first side of the cabinet and coupled with the supply duct;    at least one first outlet for discharging air into the room; and    a second outlet formed on the first side of the cabinet having the second inlet formed thereat, and coupled with the supply duct.    
   
   
       4 . The ventilating system of  claim 3 , wherein the cabinet further comprises a filter for purifying at least one first outlet.  
   
   
       5 . The ventilating system of  claim 4 , wherein the cabinet further comprises: 
 a third inlet for drawing in room air and communicating with the exhaust duct; and    a fan for generating an air suction force so as to draw in air into the cabinet.    
   
   
       6 . The ventilating system of  claim 5 , wherein the filter purifies air flowed into the cabinet through the first inlet and the second inlet.  
   
   
       7 . The ventilating system of  claim 6 , wherein the filter is provided between the first inlet and the fan.  
   
   
       8 . The ventilating system of  claim 7 , wherein the supply duct guides outdoor air to between the first inlet and the filter.  
   
   
       9 . The ventilating system of  claim 6 , wherein the fan comprises a centrifugal fan.  
   
   
       10 . The ventilating system of  claim 6 , further comprises an air cutoff for selectively cutting off outdoor air flowed into the cabinet through the supply duct.  
   
   
       11 . The ventilating system of  claim 10 , wherein the air cutoff is provided at either side of the second inlet or the supply duct of the cabinet.  
   
   
       12 . The ventilating system of  claim 6 , wherein the cabinet further comprises a suction louver for opening/closing the first inlet.  
   
   
       13 . The ventilating system of  claim 3 , wherein the cabinet further comprises a wind-direction controlling louver for controlling a direction of air discharged from the at least one first outlet.  
   
   
       14 . The ventilating system of  claim 3 , wherein the first inlet is formed at a center of a surface facing an interior of the cabinet, and the at least one first outlet is formed at an edge of a surface facing the interior of the cabinet.  
   
   
       15 . The ventilating system of  claim 14 , wherein the at least one first outlet is formed at a second edge except an edge of a side coupling the supply duct with the exhaust duct.  
   
   
       16 . The ventilating system of  claim 1 , further comprises a regeneration heat exchanger for exchanging heat between outdoor air guided by the supply duct and room air guided by the exhaust duct.  
   
   
       17 . The ventilating system of  claim 1 , wherein the supply duct and the exhaust duct are mounted in a direction perpendicular to a thickness direction of a ceiling or a wall having the cabinet mounted thereon.  
   
   
       18 . The ventilating system of  claim 1 , wherein the cabinet is formed in a hexahedral shape.  
   
   
       19 . A ventilating system comprising: 
 a cabinet mounted in a ceiling or a wall of a room, formed in a hexahedral form, and having a first inlet for drawing in interior air and a first outlet for discharging purified air into the room, both the first inlet and the first outlet formed respectively on a surface facing the room;    a supply duct coupled with a first side of the cabinet and guiding outdoor air to the cabinet; and    an exhaust duct coupled with the first side of the cabinet, which the supply duct is coupled on, and guiding interior air to an outside thereof,    wherein, the supply duct and the exhaust duct are mounted in to be parallel to each other in a direction perpendicular to a thickness direction of a ceiling or a wall having the cabinet mounted thereon.    
   
   
       20 . The ventilating system of  claim 19 , wherein the cabinet further comprises: 
 a third inlet for drawing in interior air and communicating with the exhaust duct;    a damper for selectively cutting off air flowed into the cabinet through the supply duct; and    a regeneration heat exchanger for exchanging heat between outdoor air guided by the supply duct and interior air guided by the exhaust duct.
