Description

Technical Field

[0001] The utility model relates to the technical field of rotary wheel dehumidification, in particular to a device system for dehumidifying and stabilizing pressure by using return air of a rotary wheel dehumidification unit. Background Technique

[0002] By using the return air of the rotary wheel dehumidification unit, when the positive pressure in the workshop reaches the set value, the fresh air valve is closed and the primary return air valve is opened to ensure that sufficient air volume passes through the rotary wheel dehumidification and enters the workshop, so that the humidity of the workshop can be more effectively controlled by the rotary wheel dehumidification, and at the same time, the air pressure value in the workshop can be stabilized.

[0003] The existing rotary wheel dehumidification unit relies on manually controlling the air volume of the fresh air passing through the rotary wheel dehumidification and entering the workshop to meet the humidity requirements of the workshop. However, in actual production, the continuous entry of fresh air will cause the air pressure in the workshop to rise continuously, which will have a certain impact on some automatic sealing doors and windows in the workshop, and even damage them. Therefore, it is necessary to stabilize the air pressure value. By manually closing the fresh air valve slightly, the humidity of the workshop cannot be guaranteed.
