      HF-CS type anti-condensation intelligent dehumidification device product manual

      The HF-CS type anti-condensation intelligent dehumidification system is composed of a power supply system, an air supply system, a semiconductor refrigerator, a temperature and humidity detection control circuit, an RS485 communication module, and a drain pipe. It is also equipped with a heating circuit and a wireless communication module. As the core component of the intelligent dehumidification system, the damp air flows through the specially designed air duct after the moist air is sucked in through the sub-system, and firstly passes through the peltier cooler to cool down and condense, and the condensation of the cooler drips into the air under the action of gravity. The sink is drained out of the cabinet by the water pipe. After fully circulating dehumidification within the set start value, the air humidity in the cabinet is reduced to below the dew point, and the entire moisture-proof condensation process is completed. At the same time, the signal acquisition sensor of the intelligent dehumidification system is external, which can be accurate in real time.
