The principle of semiconductor refrigeration and refrigeration dehumidifier The water and gas molecules in the air reduce the temperature of the air cooler below the air dew point temperature under the cooling effect of the semiconductor cooler. The fan draws the humid air into the machine and heats it with the semiconductor refrigerator.Exchange, the water vapor in the humid air is condensed into water droplets to discharge the body or into the water tank of the machine body, and the dry air is discharged into the room. This circulation reduces the humidity in the room and gradually achieves the dry effect.Semiconductor dehumidifier humidity adjustment The target humidity can be set locally or remotely through the 485 communication interface to achieve the purpose of free humidity adjustment and LCD humidity display.
