SHARE:
1. Air supply system: if the filter is dirty and blocked, the low wind gear is used in the humid environment, the air volume is small, the evaporation temperature of the inner machine is reduced, the evaporator frosts or even freezes, and the water leakage is caused for a long time
2, drainage system: mainly including the internal machine before and after the drainage tank, drainage pipe, pipe dressing, drainage pump failure, etc., when the air conditioner is used for a long time, the drainage tank, drainage pipe may be blocked by dirty water leakage, the drainage tank is cracked due to injection molding, the connection pipe joint is not good, the drainage pipe installation is squishing will cause water leakage.
3, the system lacks fluorine, evaporator half blocked: In the case of semi-blocked evaporator, the temperature of the long U tube fin with large refrigerant flow is low, and the temperature of the long U tube fin with small refrigerant flow is high, resulting in a large temperature difference between the two flow paths, and the long U tube fin with large refrigerant flow condenses a lot of condensate, and is blown out with the wind, and the cold and hot air converge in the air duct, water vapor condenses in the air duct, and finally leads to water leakage.
4, installation problems caused by water leakage: mainly concentrated in the new installation machine, or winter installation of air conditioning, because the installation is not horizontal or drainage pipes, connection pipe joints are not wrapped.
