The reason why dehumidifier is not dehumidified

In summer, there is a lot of rain in the south, and the air humidity is relatively high. People with rheumatism and arthritis are very sad, so many people buy dehumidifiers. How is dehumidifier sometimes not dehumidified to return a responsibility? Xiaobian summed up some reasons for not dehumidification. Let's have a look.

What is the reason why dehumidifier does not dehumidify

1. The inlet and outlet grilles are broken

If the dehumidifier cannot be dehumidified normally, check the ventilation system of the dehumidifier first. Because the air inlet and outlet grids will be damaged with the use time, the damage of the air inlet and outlet grids will also affect the dehumidifier operation, so it's OK to replace a new one at this time.

2. Clogged or damaged filter screen

There are many dusts in some areas. If the dehumidifier is used in these areas, the air filter screen of the dehumidifier will be blocked by a lot of dust, and the air flow will be greatly hindered, resulting in poor dehumidification effect. At this time, it is necessary to clean the air filter screen, clean it with clean water or blow it with air, and restart it after cleaning, so that the function of the dehumidifier will be restored. It is very common that the filter screen is blocked by dust. If it is damaged, it should be replaced. Another is to see whether the evaporator surface has icing phenomenon and dust. Sometimes, the leaves of the small dehumidifier are blocked by dust.

3. Caused by compressor and fan

Check the working condition of compressor and fan. Check the power supply and switch. If it's a refrigeration system fault or a compressor fault, the user usually can't fix it by himself. At this time, the user should ask a professional to repair it.

4. Unreasonable position of dehumidifier

Another possibility is that the location of the dehumidifier is unreasonable. Some users put the dehumidifier in the corner of the room, and the humidity in the room is not easy to flow to the dehumidifier to dehumidify. If there is an obstacle blocking the air inlet and outlet, the air volume through the dehumidifier will be reduced more, so the air temperature after the condenser is heated will rise higher, which will lead to poor condensation effect The dehumidification effect is also very poor. At this time, it is necessary to adjust the position so as to give full play to the dehumidifier's dehumidification effect.

5. Refrigeration system failure

If it is this problem, first check whether there is leakage of refrigerant and whether the refrigeration system is blocked. If so, dredge the refrigeration system. If there is leakage, first repair the leaking place and install refrigerant.

Sometimes after the dehumidifier is turned on, it is found that there is no dehumidification work. What's the matter? It is likely that there is a fault in some part of the machine. It is likely that the following problems occur.

Precautions for use of dehumidifier

1. The dehumidifier shall not be placed beside the heat source when it is used, and the air inlet and outlet shall be kept unblocked. Generally, the dehumidifier shall be placed in the center of the room in a proper position, and there shall be enough space around, and no articles shall be stacked. Keep the air smooth, the effect of dehumidification can be even.

2. When the refrigerated dehumidifier is used in low temperature (below 18 ℃), it will frost or freeze. The dehumidifier with defrosting function can automatically frost, but the dehumidifier without defrosting function can be defrosted manually (power off). In general, the temperature is low, the humidity is also low, the humidity is lower than 40%, the dehumidification effect may not be obvious, and the speed is slow, which is a normal phenomenon.

3. It is suggested to adjust the set humidity of dehumidifier to between 50% and 60%. If it is set too high, the dehumidifier will not achieve the dehumidification effect, and if it is set too low, it will cause the dehumidifier to work frequently, which is not conducive to human health, and it is easy to accelerate the life of the dehumidifier.

4. We can also use dehumidifier to dry quilts and mattresses. The specific operation is to close the door of the room and close the windows. When there is no one, set the humidity of dehumidifier as dry clothes, and when there is someone, set the humidity as comfortable.

5. Dehumidification capacity is measured under standard environmental conditions. If the dehumidification capacity is 50 L / day, it means the volume of effluent measured at 30 ℃ / RH80% for 24 hours. During the operation of dehumidifier, it is a normal phenomenon for the machine to exhaust hot air from the air outlet. In winter, the humidity is low, and the temperature of the air outlet also drops obviously, which is a normal phenomenon.
