First of all, we need to see whether the installation of the machine body is standardized. For example, the connection of the four walls of the vent is uneven and not sealed, which is easy to cause dripping, or on the surface, the air outlet is lower than the sink of the indoor unit, but due to the air pressure in the drain pipe, the sleep in the sink cannot be discharged and flows indoors, resulting in water leakage at the air outlet of the indoor unit.
Solution: To deal with water leakage caused by improper installation, it is best to reprocess the passage from indoor water pipes to outdoor.
Second, improper use of air conditioning.
Improper use will also lead to the problem of water leakage in the indoor unit of central air conditioning. How can it be regarded as improper use by users? For example, the user puts the water receiving container under the indoor or outdoor drainage pipe, and the water in the water receiving container often floods the water pipe mouth. At this time, due to the action of atmospheric pressure, the water that is not easy to be discharged from the drainage pipe gradually overflows to the mouth of the indoor water receiving cylinder, resulting in water leakage.
Solution: just hang the drain pipe above the water receiving container, but don't bend the drain pipe excessively.
Third, the air humidity is too high.
The temperature around the air outlet of the central air conditioner is low, and if the ambient air humidity is high, water leakage will also occur.
Solution: When this phenomenon occurs, the air supply temperature can be appropriately increased, the cold air supply volume of central air conditioning can be increased, and the wind speed can be adjusted as high as possible.
Fourthly, the refrigerant problem.
The central air conditioner needs refrigerant, and the lack of refrigerant will cause water leakage in the indoor unit of the air conditioner. The reason is that the refrigerant evaporates at the inlet of the evaporator, causing frost on the tube wall. After a period of time, the thickness of the frost layer increases continuously until it exceeds the edge of the sink and even contacts the panel of the indoor unit. Due to the influence of external hot air, the external melting of the frost layer increases continuously until it exceeds the edge of the sink and even contacts the panel of the indoor unit. Due to the influence of outside hot air, the external melting of frost layer leads to dripping.
Solution: If the indoor unit leaks due to the refrigerant problem, you can replenish the refrigerant and the leakage will disappear.
Five, copper tube insulation cotton is not included.
The indoor pipes of central air conditioning are all copper pipes, and the refrigerant temperature in the copper pipes is very low. If the insulation cotton is not tightly wrapped, or the poor quality insulation cotton can not play a good role in insulation, there will be a lot of condensed water in the pipeline, which will drip down and soak smallpox.
Solution: It is suggested to choose some thermal insulation cotton with better quality, and use thermal insulation cotton with corresponding aperture for copper pipes with different diameters. When wrapping the thermal insulation cotton, pay attention to not leaving any gap between the thermal insulation cotton and the copper tube, and ensure that the copper tube will not be exposed.
Six, the drain pipe and indoor machine connection is not good.
The drain pipe is mainly used to drain the condensed water from the indoor unit. When connecting with the indoor unit, use soft connection and clamp it with a clip. If the connection is not tight, condensed water will flow out of the gap.
Solution: After the indoor unit is connected to the drain pipe, conduct a drainage experiment to ensure that the connection is tight and there will be no water leakage.
Seven, condensed water drainage.
The condensate outlet of indoor unit is blocked or the slope of drainage pipe is not enough, which will lead to poor drainage and accumulation on the water tray of indoor unit. When the water dish is full, it will overflow and soak the ceiling.

Method: During construction, ensure that the drainage slope of condensate water is not less than1100. Before connecting the drain pipe to the indoor unit, please check whether the outlet of the indoor unit is dirty or blocked. After the drainage pipe is completed, ensure that the condensed water can be discharged smoothly.
Eight, the filter screen is dirty and blocked.
The low wind barrier is used to filter the dirty and humid environment. The air volume is too small, the internal evaporation temperature decreases, and the evaporator frosts or even freezes for a long time, resulting in water leakage. The filter is dirty and blocked, which leads to a lot of water leakage, so users should pay attention to cleaning the filter regularly when using air conditioning.
