1. Installation position is too low.
Condensed water is mainly discharged in the form of "water flowing downwards", so the air conditioning hole is usually lower than the height of air conditioning installation. If the slope is not enough, the condensed water can't flow out and can only flow back to the sump. This situation is because the air conditioner is not well planned and has to be reopened.
2. The drain pipe is blocked.
When installing the air conditioner, reserve a special drainage pipe. If the drain pipe is blocked, the condensed water in the air conditioner cannot be discharged normally, and then flows back to the lowest point of the indoor unit and flows out from the air outlet of the air conditioner. The solution is to pull out the outdoor drain pipe and blow a lot of air into it until the blockage is blown away, and the water can naturally be discharged smoothly.
3. The filter is too dirty
If the filter screen of air conditioner is not cleaned for a long time, dust accumulation will cause the hydrophilicity of hydrophilic aluminum foil of air conditioner to become worse. After air conditioning refrigeration, condensed water can not directly flow into the sink, but will drip into the room from the indoor machine. The solution is to clean the air conditioning filter regularly.
4. Internal machine deviation.
The indoor unit of air conditioner shall be installed horizontally. If it is inclined, the pipeline intersection position is high, which will cause blockage when dew is discharged, and also cause dripping. Faced with this situation, the body of indoor air conditioner should be adjusted to a horizontal position in time, and the drain pipe should be lowered if it is too high.
5. Insufficient refrigerant
Air-conditioning running in the absence of fluorine is easy to cause the evaporator to freeze. When the ice melts into water droplets, the water droplets directly drip into the room from the gap of the air conditioner, which leads to the phenomenon of water dripping in the air conditioner. The solution is to contact after-sales maintenance to replenish refrigerant for the air conditioner.
