Ventilation system

Abstract

A ventilation system is disclosed. The ventilation system of the present invention includes a heat-exchanger having at least two unit heat-exchange elements arranged in parallel for heat exchange between supplied outside air and exhausted room air, an air-supply duct having one side for making an outdoors be in communication with an inside of the heat-exchanger and the other side for making an indoor space be in communication with the inside of the heat-exchanger to supply outside air into the indoor space, and an air-exhaust duct having one side for making the indoor space be in communication with the inside of the heat-exchanger and the other side for making the outdoors be in communication with the inside of the heat-exchanger to exhaust room air outdoors, wherein an air-supply channel is formed for making one side of the air-supply duct be in communication with the other side of the air-supply duct and an air-exhaust channel is formed in a diagonal direction of the air-supply channel for making one side of the air-exhaust duct be in communication with the other side of the air-exhaust duct within the heat-exchanger.

1 . A ventilation system comprising: 
 a heat-exchanger having at least two unit heat-exchange elements arranged in parallel for heat exchange between supplied outside air and exhausted room air;    an air-supply duct having one side for making an outdoors be in communication with an inside of the heat-exchanger and the other side for making an indoor space be room in communication with the inside of the heat-exchanger to supply outside air into the indoor space; and    an air-exhaust duct having one side for making the indoor space be in communication with the inside of the heat-exchanger and the other side for making the outdoors be in communication with the inside of the heat-exchanger to exhaust room air outdoors;    wherein an air-supply channel is formed for making one side of the air-supply duct be in communication with the other side of the air-supply duct and an air-exhaust channel is formed in a diagonal direction of the air-supply channel for making one side of the air-exhaust duct be in communication with the other side of the air-exhaust duct within the heat-exchanger.    
   
   
       2 . The ventilation system of  claim 1 , further comprising, 
 an air-supply fan scroll having an air-supply fan for supplying outside air into the indoor space in the air-supply channel and a motor for operating the air-supply fan, and    an air-exhaust fan scroll having an air-exhaust fan for exhausting room air outdoors in the air-exhaust channel and a motor for operating the air-exhaust fan.    
   
   
       3 . The ventilation system of  claim 2 , wherein the air-supply fan scroll and the air-exhaust fan scroll are provided in the same portion of the heat-exchanger with respect to the heat-exchange element.  
   
   
       4 . The ventilation system of  claim 3 , wherein the air-supply channel and the air-exhaust channel are in right/left and upward/downward symmetry.  
   
   
       5 . The ventilation system of  claim 4 , further comprising a guide for partitioning off the air supply channel from the air-exhaust channel.  
   
   
       6 . The ventilation system of  claim 5 , wherein the heat-exchanger further comprises, 
 a bypass channel for supplying outside air into the indoor space without outside air passing the unit heat-exchange element, and    a bypass damper for selectively shutting off the bypass channel.    
   
   
       7 . The ventilation system of  claim 2 , wherein the air-supply fan and the air-exhaust fan are double suction fans, respectively.  
   
   
       8 . The ventilation system of  claim 1 , wherein the unit heat-exchange element is a total-heat-exchange element.  
   
   
       9 . The ventilation system of  claim 8 , wherein the unit heat-exchange element is a hexagonal parallel type heat-exchange element.  
   
   
       10 . The ventilation system of  claim 8 , wherein the air passing through the unit heat-exchange element is drawn from an air drawing surface of the unit heat-exchange element in a diagonal direction with respect to a center of the unit heat-exchange element and discharged from an air discharging surface of the unit heat-exchanging surface in a diagonal direction with respect to a center of the unit heat-exchange element.  
   
   
       11 . The ventilation system of  claim 10 , further comprising a channel guide casing formed on an air drawing surface and an air discharging surface of the unit heat-exchange element to drawn/discharge air in a diagonal direction with respect to the center of the unit heat-exchange element.  
   
   
       12 . The ventilation system of  claim 10 , wherein the air-supply channel and the air-exhaust channel are partitioned by a guide within the heat-exchanger, the air-supply channel and the air-exhaust channel are in a right/left and upward/downward symmetry within the heat-exchanger.
