Humidity control method

Abstract

The invention discloses a humidity control method. The humidity control method has the following process: a humidity detecting circuit performs A / D conversion for a present environment humidity signal to send into a processor AT89C51; then, the processor displays the present humidity signal through an LED through operation of software; a relative humidity value is displayed; the processor judges if the present humidity value is located in a preset range through program operation; if not, a system can automatically adjust the humidity; when the humidity detecting circuit detects that the present environment humidity is higher than the upper limit of a set value, a microprocessor enables P2.6 to output low level; a humidity reducing control circuit is started to enable an air blower to start to work for exhausting, heat dissipation and cooling; and when the humidity detecting circuit detects that the present environment humidity is lower than the humidity set lower limit, P2.7 output outputs low level, so that a steam engine control circuit works for heating to increase the humidity.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a humidity control method. Background technique [0002] With the rapid development of science and technology, the ambient temperature and humidity are becoming more and more important. The heat dissipation of the power components in the electric control parts of the existing DC frequency conversion multi-connected outdoor units mainly uses fans for heat dissipation, but the heat dissipation effect is not good, especially in The cooling effect is worse in high temperature environment. [0003] Therefore, it is necessary to provide a new humidity control method to avoid the above defects. Contents of the invention [0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a humidity control method that can automatically adjust the relative humidity of the current environment. [0005] A humidity control method, t...
