If the zone where the air humidity exists is a low humidity zone (for example, the air humidity is 20% -60%), the number of the moisture-proof boards corresponding to the zone is 1. If the interval in which the air humidity is located is a medium-humidity interval (for example, the air humidity is 60% -90%), the number of the moisture-proof plates corresponding to the interval is an integer which is larger than 1 and smaller than N, and N is the total number of the moisture-proof plates in the fresh air machine. If the zone where the air humidity exists is a high humidity zone (for example, the air humidity is more than 90%), the number of the moisture-proof boards corresponding to the zone is N.
