There are many reasons for the leakage of air conditioning, careful observation of the process, the key to find water, and then targeted treatment. In general, Water Leakage can be analyzed from the following aspects: (a)

, air
1, air conditioning system: after a long time, the filter dust dirty block, reducing internal air flow inside the machine, the evaporation temperature decreased, the work time of evaporator frosting or even freeze for a long time, resulting in Water Leakage.
2, air conditioning is used for a long time, the surface of the evaporator is dirty, decreased hydrophilicity of condensed water evaporator aluminum foil, can not be drained to the sink, and because of dirty air flow within the evaporator will reduce the work for a long time after Water Leakage.
3, the use of low wind speed in a humid environment, the motor speed is slow, volume is small, the machine evaporation temperature decreased, the work time of evaporator surface frost or ice for a long time to Water Leakage, and plastic parts inside the machine and sheet metal may also be due to temperature difference between inside and outside is too big and formed on the surface of dew condensation.
4, insulation paste is not too large, the temperature difference between inside and outside the plastic surface Water Leakage.
5, in the machine air duct sealing leakage, hot air without cooling evaporator directly into the air duct, and through mixing the evaporator cooling air dew, long time will produce Water Leakage.
(two), mainly including: the drainage system before and after the machine guide tank and the drainage tube, drainage pipes, pump failure:
1, when the air conditioner is used for a long time, a guiding groove, drainage pipe may be blocked by dirt, water can not be discharged smoothly to Water Leakage.
2, guide groove and so on because of bad injection of cracks, water from the cracks in the internal leakage.
3, guide for injection outlet not bad tank open, water can not flow to the outlet pipe to Water Leakage.
4, drainage pipe and the junction of the water tank off, sealed bad lead to leakage.
5, drainage tube is not well wrapped, thermal insulation performance is not good, the surface of the formation of dew.
6, drainage tube rupture, resulting in flattening Water Leakage.
7, drainage pipeline is too long, uneven, twisted, bending causes leakage.
8, the drainage pipe connection is not caused by water leakage. The connection between the
9 and the connection of the connecting pipe is not good, and the dew point is generated.
10, after the evaporator water plate is not installed lead to leakage.
11, drainage pump failure caused by leakage.
(three): system of refrigeration system, evaporator, lack of fluoride liquid plug lead in machine Water Leakage:
1 system, lack of fluoride under the condition of low pressure system, reduce the evaporation temperature of refrigerant in the evaporator, enter quickly near the input tube of 2-3 root length in the U tube evaporator gasification, so close to the input 2-3 the root length of U tube fin temperature is low, while the other U long tube fin temperature close to room temperature, so close to the input 2-3 root length U tube fin condensation on a large number of condensation water, a long time will produce ice ice frost, finally Water Leakage.
2, in the case that the evaporator is partly blocked or completely blocked, the flow rate of the refrigerant is not large, and the fin temperature is low. The welding part of less or no blocking refrigerant refrigerant flowing through the fin, low or high temperature, resulting in a flow path between the air after two large temperature difference between the condensation amount of condensation water refrigerant through the fins, and the intersection of cold and hot air in the air duct, air duct wall into dew condensation in the condensate, and finally lead to Water Leakage blowing out.
(four), the installation problem caused by water leakage, the main reasons are:
1, internal hanging board installation is not the level of water leakage.
2, the internal hanging plate installation is not close to the wall leading to leakage.
3, out of the hole in the wall of the high and low water can not discharge water leakage.
4, the drainage tube, low distortion, uneven, winding, and as a result of Water Leakage flattened tight bandage.
5, the connection pipe is not well wrapped lead to leakage.
6 not installed side guard plate, cabinet, pipe of sheet metal cutting burr Water Leakage.
7, the drainage pipe wrapped tightly compressed to Water Leakage.
8, drainage pipe connecting pipe in a wall hole bending crushed Water Leakage.
