Why does the car air conditioning pipe leak?
1. The air conditioner dropper under the car is dripping, which is a normal phenomenon and there is no need to worry.
2. The drainpipe of the evaporator shell is blocked, causing the water level to overflow. At this time, you need to clean the evaporator shell drain pipe.
3. Evaporator shell rupture, easy to be mistaken for air conditioning pipe leakage. In this case, the evaporator housing needs to be replaced.
4. Poor insulation of evaporator shell or air conditioning pipe may also lead to water leakage of air conditioning pipe. It is recommended that the owner go to the 4S shop or repair shop for repair, because the personal solution to this problem may cause new problems and cause unnecessary losses.
5. When the air is too cold, the moisture at the exit will condense, and when the external air circulation function is used, the high-humidity air will continue to enter the car, resulting in the inability to discharge the moisture in the car. This is a normal phenomenon and does not need to be dealt with.
6. Drainage pipe problems, such as loose or bent into a wavy shape, may cause poor drainage. The drain pipe needs to be repaired or replaced.
7. Dew on the pipe may be caused by the poor quality or thin insulation material on the pipe, which causes condensation when the refrigerant passes through. You can choose not to deal with it or replace the piping.
Car air conditioning pipe leakage how to do
1, soapy water detection. You can apply soapy water on the car air conditioning pipe, the location of bubbles indicates that there is a leak, may leak more than one place, need to carefully check, and then replace the damaged pipe.
2. Dye detection. Put the dye with the color into the air conditioning pipe, then turn on the air conditioning and turn on the refrigeration system. Dye can flow out of leaks in air conditioning pipes or leave stains near the leak site. You can use a flashlight to check the various parts of the car air conditioning pipe, carefully check and then complete the corresponding replacement.
3, electronic leak detector detection. You can go to the professional repair shop to use the leak detector to detect the air conditioning pipe, when the leak is detected, the leak detector will issue a warning signal, and then replace the corresponding pipe.
If air leakage occurs in the air conditioning pipeline, it will not only produce air in the pipeline, but also cause refrigerant leakage, affecting the cooling effect, or even not cooling.
Usually also need to maintain the air conditioning pipe, when using air conditioning, before the car is turned off, it is necessary to turn off the air conditioning first, empty the air conditioning, to avoid the air conditioning pipe has gas residue, resulting in corrosion and deterioration of the air conditioning pipe.
If there is an air leakage problem in the air conditioner, in addition to the air conditioning pipe leakage, there may also be a leak in the air conditioning compressor or expansion valve.
Air conditioning compressor belongs to the internal component of air conditioning, and its stroke end may have the phenomenon of insufficient sealing tightness. At the end of the stroke, the high compression of the refrigerant may lead to excessive high pressure and the need to replace the compressor.
Expansion valve leakage may also make the car air conditioning leakage phenomenon, also need to be replaced in time.
