Embodiment Construction

[0028] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0029] figure 1 is an overall flowchart of the dehumidification method according to the embodiment of the present invention.

[0030] Step S100: The sensor senses the humidity value at the air inlet of the air duct. The humidity value is the relative humidity value, which is the ratio of the absolute humidity of the humid air to the maximum absolute humidity that may be reached at the same temperature, or the ratio of the partial pressure of water vapor in the humid air to the saturation pressure of water at the same temperature. The sensor is a relative humidity sensor, which is arranged at the air inlet of the air duct, and senses the relative humidity value of t...

Abstract

The invention provides a dehumidifying method. The dehumidifying method comprises the following steps: a sensor is used for sensing the humidity value of an air inlet of an air flue; when the humidity value is greater than or equal to a first humidity threshold, a dehumidifying control device starts a dehydrating unit for dehumidifying the air flue; and when the humidity value is greater than or equal to a second humidity threshold, and a dehumidifying control device closes the dehydrating unit so as to stop the dehumidifying operation. In the method, through setting the first humidity threshold and the second humidity threshold, the humidity in a machine room air environment is controlled in the range required by a user, the automatic control of effective dehumidification is realized, the service life of a dehumidifying system is prolonged, and the energy consumption is reduced. The invention also discloses the dehumidifying system.

Description

technical field [0001] This invention relates generally to air handling equipment and, more particularly, to methods and apparatus for dehumidification. Background technique [0002] If the air humidity is too high, the contact resistance of the plug-in at the joint of the component will increase, causing it to operate incorrectly, and the components that are not well sealed may be broken down. Rapid changes in relative humidity will shorten the life of components such as transistors. If the humidity control is not good, it will cause condensation on the wall of the computer room and the inside of the program-controlled machine, which will easily cause corrosion and mildew, and cause the circuit components of the program-controlled machine to short-circuit, causing failures and accidents. For computer rooms that require relatively high air relative humidity, it is necessary to be equipped with a dehumidification device. [0003] A dehumidifier with adjustable dehumidificat...
