Design and Implementation of Dehumidifier for Control Panel by Using the Hot and Cold Functionality of the Thermoelectric Module

This paper, is to prevent failure due to moisture in the industrial control panels. Dehumidifier is operate when measuring the internal temperature of the panel, temperature is higher(during operation) thermal module cooling(cooling dehumidification) to dehumidify and low(shutdown) a thermoelectric module heat(dehumidifying heat) to remove moisture. Dehumidifier is implemented using thermoelectric module to controller a proportional of the temperature and humidity. Inside sensor is measuring temperature and humidity in order to protect the PCB circuit. Thermoelectric module according to the model size and the property is also a very important design element to the heat sink structure to maintain a proper heat resistance and vary according to the type of Module. By implementing the dehumidifier for control panel functions of the thermoelectric elements using a cold was confirmed that no noise, vibration-free, can be an effective dehumidifier by a low energy consumption of the local space.
