The present invention relates to a ventilating apparatus which minimizes the flow resistance of air flowing into a blower fan, and which reduces the noise generated by the air being discharged from the ventilating apparatus, thereby minimizing the noise generated inside the ventilating apparatus.
Claims20
A ventilating apparatus comprising:
- a housing which forms an air supply flow passage for introducing outdoor air into a room, and an air discharge flow passage for discharging room air to outdoors;
- an air discharge fan provided to the air discharge flow passage for discharging the room air
- an air draw-in fan provided to the air supply flow passage for drawing-in outdoor air;
- and
- a guide duct having a duct frame provided in the housing for changing and air discharge direction of the air being discharged from the air discharge fan.

A ventilating apparatus comprising:
- a housing which forms an exterior;
- an air draw-in fan having a cross flow fan with a direction of a rotating shaft perpendicular to a length direction of the housing for drawing-in outdoor air;
- an air discharge fan having a cross flow fan with a direction of a rotating shaft parallel to a length direction of the housing for discharging room air;
- a heat exchanger for making the outdoor air being drawn by the air draw-in fan to heat exchange with the outdoor air being discharged by the air discharge fan;
