Ventilation device

This creation relates to a ventilation device, in particular to a ventilation device having a power saving effect.

The machine inside the factory or machine room is often accompanied by the generation of heat energy. The heat generated by the machine will be concentrated in the factory or machine room, so that the indoor temperature in the factory or machine room will increase, and the excessive indoor temperature will be possible. The operation of the machine has a bad influence; therefore, a ventilation system is usually installed in the factory or the machine room to allow the air in the factory or the machine room to circulate with the outside air to avoid excessive indoor temperature in the factory or the machine room.

The current ventilation system is equipped with a plurality of fans on the walls of the factory or the machine room. The pumping of the fans allows the air in the room to circulate with the outside air; however, the fans operate with great noise.
