A small dehumidifier simply uses the moisture in the air to condense and frost when it enters the evaporator of the dehumidifier, and then accumulates and drips out and discharges into the drain, so as to achieve the purpose of reducing the humidity of the space. The principle of dehumidification is similar. The air is condensed into water and discharged to balance the air temperature in the room.
Because the fresh air dehumidifier dehumidifies the outdoor air at one time, while the ordinary dehumidifier is placed indoors, it belongs to the circulation and progressive dehumidification. Therefore, if the target humidity of the two is the same, the difference in the moisture content of the former is much larger than that of the latter in a unit time. Therefore, when calculating the humidity load, it is necessary to fully consider the "one-time" dehumidification ability of the fresh air dehumidifier.
After the dehumidifier is used for a period of time, its air inlet filter will accumulate dust, and the dust accumulation is too dense and thick, which will affect the dehumidification effect. Therefore, it is necessary to clean the filter screen frequently to make the front and rear ventilation smooth.
