When the air conditioner is operating in summer, the air humidity is high. When the heat exchanger of indoor unit exchanges heat through the fan, condensate will be generated due to the low temperature. If there is drip or water leakage under the indoor unit.

1. Poor drainage pipe: due to the relaxation or bending of drainage pipe into wave shape, resulting in poor drainage.

2. Improper installation of the body: the indoor unit is inclined, and the direction of pipe intersection is too high.

3. Heat exchanger drip:

a. The lack of refrigerant in the air conditioning system causes the indoor unit to freeze, and the water droplets formed by ice melting do not directly drip into the water pan. This situation is generally not easy to deal with, to be solved by professional maintenance personnel.

b. When the air conditioner is operating in summer, the air humidity is high, and the heat exchanger is covered with dust, which causes uneven temperature of heat exchange. Water drops are produced in the middle of the heat exchanger, and the water drops falling outside the water tray will drop into the room.

4. Condensation water on Piping: due to the poor or thin insulation material on the pipeline, condensation occurs when refrigerant passes through the pipe.
