Abstract:
1. A ventilating system comprising: a total heat exchanger at a region where an air supply duct, a passage for supplying outdoor air to a room, and an air discharge duct, a passage for discharging room air to an outside of the room, cross for making room air and outdoor air to heat exchange; an air supply fan connected to the air supply duct for drawing the outdoor air and discharging the outdoor air to the room; an air discharge fan connected to the air discharge duct for drawing the room air and discharging the room air to an outside of the room; and a plurality of flow distribution members partially partitioning space between a side surface of the total heat exchanger and a case forming an exterior of the ventilating system into several flow passages to make a substantially uniform distribution of the air drawn by the air supply and discharge fans and being supplied to the total heat exchanger, the plurality of flow distribution members includes a plurality of first flow distribution members for distributing the outdoor air being introduced into the total heat exchanger and a second flow distribution member for distributing the room air being introduced into the total heat exchanger, wherein, an air supply duct inlet of the air supply duct and an air discharge duct inlet of the air discharge duct are parallel with the side surface of the total heat exchanger along a length of the total heat exchanger, and the first flow distribution members have sizes which become larger as the distances of the first flow distribution members from the air supply duct inlet become greater.
