Working principle: (using a new type of electronic dehumidification controller)The dehumidification controller is equipped with up and down hinged doors, and each has a pair of moisture absorption and moisture removal inside and outside (for the cabinet), and special moisture absorption materials are enclosed. When moisture is absorbed, the flap door is opened to the inside, and the moisture-absorbing material absorbs the moisture in the cabinet from the moisture-absorbing window to reduce the humidity in the cabinet; when the moisture is exhausted, the moisture-absorbing material is heated to regenerate, and the valve rotates to open the moisture exhaust window outside the cabinet to drain moisture. Moisture absorption and discharging cycle work, realized by the program time controller, until the cabinet in the cabinet reaches the set value, the controller automatically cuts off power, because when absorbing moisture, there is no need to power on, and the moisture absorption time is long (about 4.5), and the moisture is discharged When the power-on time is short (about 40 minutes), it is extremely power-saving (about 1/4 power-saving than other types of controllers)
