Abstract

The invention relates to a control system of humidifier and relative control method, wherein said system comprises a programmable controller, a touch display, a switch valve input / output module, an analogue valve input / output module, a frequency changer, a separated transformer, a power filter, and a DC24V power source. The control system via the analogue value input / output module obtains the on-site signal of humidifier; and the control system via the switch valve input / output module controls the water inlet, outlet and discharge of humidifier; said control method comprises: selective washing process and needed humidifying process; in the washing process, user can set the washing time; in the humidifying process, user can select pressure-constant mode, current-constant mode or variable mode; and the control system, via selected limits, humidity real valve, remote signal control, or network control, controls the humidification. The invention has stable pressure.

Description

Technical field: [0001] The invention relates to a humidifier control system and a control method thereof, which are mainly used for controlling the operation of the humidifier. Background technique: [0002] The existing high-pressure micro-mist humidifiers in China are mainly composed of electric motors, high-pressure pumps, frequency converters, humidity controllers, solenoid valves, and water tanks. The humidity control accuracy is usually + / -5%RH of the set value, the pressure control ability is not high, the control method is not flexible enough, it is easy to cause a large pressure shock, the solenoid valve is easily damaged, and the frequency converter is also easy to cause failure. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies in the prior art, and to provide a humidifier control system and a control method thereof with stable pressure control and flexible and diverse control...
