The dehumidification effect of the dehumidifier is not ideal, which is often not necessarily caused by the quality of the dehumidifier itself, and to a large extent has a lot to do with the insufficient maintenance of the dehumidifier. Therefore, when the dehumidification effect of the dehumidifier is not satisfactory, the following items should be checked first, and then the cause of the deep-seated failure should be found.

The dehumidifier leaks fluorine. It may not be that the dehumidification effect is not good, but the dehumidification is not performed.

         1. Whether the humidity set by the humidity control switch is appropriate and whether the air filter is blocked is very important. Once the air inlet is affected, the dehumidification effect is very poor. Note: Whether there is dirt and corrosion on the evaporator (especially in bad places in the workplace).

         2. Check whether there are obstacles in front of the air inlet of the dehumidifier. Is the temperature in the room rising or falling? If the indoor temperature is low, even if it is not dehumidified, it will affect the dehumidification effect. If the indoor temperature is low, a heater can be used to improve the dehumidification effect of the dehumidifier.

         3. Whether the doors and windows of the room are closed, whether the air volume is set in the "low wind" position, and the common area of the dehumidifier is inconsistent with the actual use area. (The use area is too large, the dehumidification capacity of the dehumidifier is too small, whether there are many sources of moisture in the house, whether there are many hygroscopic products in the house, whether there are exhaust and fresh air systems).

         4. Check whether the heat exchanger of the dehumidifier is blocked.

         5. Whether there is fluorine leakage in the dehumidifier and insufficient refrigerant. Under normal circumstances, fluorine leakage will not occur for a long time, and the refrigerant will leak completely in a short period of time, so the dehumidification effect is rarely bad, but it does not dehumidify.
