Description

Technical Field

[0001] The utility model relates to the technical field of fresh air systems, and more specifically to an air humidifying device. Background Art

[0002] The fresh air system is based on the use of special equipment to send fresh air to the room on one side of the closed room, and then exhaust it to the outside from the other side by special equipment, forming a "fresh air flow field" in the room, thereby meeting the needs of indoor fresh air ventilation. The implementation plan is: use high wind pressure, large flow fans, rely on mechanical force to send air to the room from one side, and use a specially designed exhaust fan to exhaust it to the outside from the other side to force the formation of a fresh air flow field in the system. While sending air, the air entering the room is filtered, disinfected, sterilized, oxygenated, and preheated.

[0003] In winter, the air is relatively dry. After fresh air is filtered, sterilized and dehumidified, it will accelerate the drying of the indoor air. Dry air will not only cause discomfort to people indoors, but also affect the mood of indoor staff. Some small humidifiers indoors have limited humidification effects and cannot change the overall indoor air environment. Therefore, it is necessary to design an air humidification device used in the fresh air system. Utility Model Content
