What is the reason for dripping water from the air outlet of air conditioner?

The main reasons for dew condensation and dripping at the air supply outlet are: 1. The air supply speed is low. 2. The doors and windows are not closed, and the indoor humidity is high. 3. The air supply temperature is too low. 4. The return air filter is blocked and water accumulates in the water tray. The tuyere of air conditioner is mainly aluminum alloy louver custom tuyere. If the aluminum alloy is too thin, it is difficult to have a high enough water retention line on its blades. However, when the tuyere temperature is about 3 degrees, water droplets are easy to appear on the blades. The more these water droplets accumulate, the more they fall vertically. Low ambient humidity or sultry summer after rain is also one of the main reasons for tuyere dripping. Because the hot air contains a lot of moisture, when the cold air outlet meets the hot air with high humidity around the tuyere, the moisture will be separated from the louver tuyere and will gather together to form a water droplet state. In addition, it is sunny after the rain, and it is easy to drip when the air conditioner is turned on at home, which is also the same reason, because there is too much water vapor in the air.
