Ventilating system

Abstract

The present invention relates to a high efficiency total heat exchange ventilating system which can prevent temperature rise of supply air caused by heat generated at a motor for minimizing reduction of total heat exchange efficiency. The ventilating system includes a case which is an exterior of the ventilating system, a total heat exchanger in the case for making heat exchange between air discharged to an outside of room and air supplied to the room, an air supply fan and an air discharge fan mounted in the same direction with reference to the total heat exchanger, and an air supply motor and an air discharge motor for supplying power to the air supply fan and the air discharge fan, respectively, wherein the air supply fan is mounted in an air flow line of the air being supplied, and the air supply motor is isolated from the air supply fan and exposed to an air flow line of the air being discharged.

1 . A ventilating system comprising: 
 a case which is an exterior of the ventilating system;    a total heat exchanger in the case for making heat exchange between air discharged to an outside of room and air supplied to the room;    an air supply fan and an air discharge fan mounted in the same direction with reference to the total heat exchanger; and    an air supply motor and an air discharge motor for supplying power to the air supply fan and the air discharge fan, respectively, wherein the air supply fan is mounted in an air flow line of the air being supplied, and the air supply motor is isolated from the air supply fan and exposed to an air flow line of the air being discharged.    
   
   
       2 . The ventilating system as claimed in  claim 1 , wherein the air discharge motor is mounted in an air flow line of the air being discharged.  
   
   
       3 . The ventilating system as claimed in  claim 1 , wherein on one side, the case includes an outdoor air inlet in communication with an outside of room, and a room air inlet in communication with the room, and on the other side, a room air outlet in communication with the outside of the room for discharging the room air to an outside of the room and an outdoor air outlet for supplying the outdoor air to the room.  
   
   
       4 . The ventilating system as claimed in  claim 3 , wherein the case includes; 
 a passage connected between the outdoor air inlet and the outdoor air outlet through the total heat exchanger, and    a passage connected between the room air inlet and the room air outlet through the total heat exchanger.    
   
   
       5 . The ventilating system as claimed in  claim 4 , wherein the outdoor air inlet and the outdoor air outlet, and the room air inlet and the room air outlet are arranged diagonally, respectively.  
   
   
       6 . The ventilating system as claimed in  claim 1 , further comprising a bypass flow line in the case so that the air flows without passing through the total heat exchanger.  
   
   
       7 . The ventilating system as claimed in  claim 6 , further comprising a damper for opening/closing the bypass flow line.  
   
   
       8 . The ventilating system as claimed in  claim 1 , wherein the air supply motor and the air discharge motor are arranged in a line along a discharge air flow direction.  
   
   
       9 . The ventilating system as claimed in  claim 1 , wherein the case includes spaces partitioned therein for housing the air Supply fan and the air discharge fan respectively, and the air discharge motor and the air supply motor are housed in an air discharge fan housing having the air discharge fan housed therein.  
   
   
       10 . The ventilating system as claimed in  claim 9 , wherein the air discharge fan housing further includes a motor housing for accommodating the air discharge motor and the air supply motor.  
   
   
       11 . The ventilating system as claimed in  claim 10 , wherein the motor housing includes an opening on a side of the air discharge fan for passing of the air being discharged.  
   
   
       12 . The ventilating system as claimed in  claim 9 , wherein the air supply fan and the air discharge fan are centrifugal fans.  
   
   
       13 . The ventilating system as claimed in  claim 9 , wherein the air supply fan and the air discharge fan are sirocco fans.
