[0002] The air conditioning fresh air device is a ventilation device used when the air conditioner is in use. In a dust-free workshop, the air conditioning fresh air device will be used to cool the interior of the workshop while keeping the internal air fresh and dust-free. When the air conditioner is used for cooling, the air outside the workshop will enter the workshop through the fresh air device. After the air is purified, the air inside and outside the workshop can be circulated.
