Compared with the prior art, this fresh air system that sterilizing power is strong with dehumidification function passes through the moisture that dehumidification mechanism lasts in the absorption air, avoids the hydrone in the air to absorb the ultraviolet ray, influences ultraviolet bactericidal effect, moreover, through heating mechanism to air heating, reduces the bacterium resistance to ultraviolet sterilizing power has been strengthened, the practicality of equipment has been improved.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
