What is the phenomenon of a broken car drying tank Maintenance of the drying tank
When you are repairing the car air conditioner, you don’t know what happens when the car drying tank is broken. The following okmarts.com editor will take you to understand the common faults of the drying tank and teach you how to repair the car air conditioning drying tank.
What is the phenomenon of broken car drying tank
The car air-conditioning drying tank is used for filtering. If it is broken, it will block and cause the air-conditioning system to not be cooled.
If the substance in the filter drier is damaged, it will cause the pipeline to be dirty and blocked.
If the filter drier absorbs too much water, the refrigeration system pipes will be blocked by ice.
The probability of failure of the filter drier is very low and generally will not be damaged.
Common failures of drying tanks
The common failure of the drying tank is that the filter element is dirty and clogged, which makes the refrigerant flow poorly, resulting in insufficient or no cooling.
How to judge the quality of the car drying bottle?
Look at the optical window on the top of the drying bottle to see if there is water mist. If it is broken, the wind from the air conditioner is not very cool.
1. The temperature of the upper part and the lower part of the bottle is different when the drying bottle is blocked, and the temperature of the two ends of the reservoir is touched by hand. The temperature difference is large and must be replaced;
2. Dirty blockage and ice blockage are generated in the system, which must be replaced;
3. The air conditioner has to be replaced due to failure or the system has been disassembled for a long time;
4. The reservoir body has leakage failure and must be replaced
5. The pressure control switch of the accumulator fails and must be replaced (the pressure switch can also be replaced separately).
1) Discharge the refrigerant.
(2) Remove the pipeline on the drying tank.
(3) After removing the fixing screws of the drying tank, remove the drying tank.
Installation of drying tank
Install the drying tank according to the steps opposite to the disassembly. After installation, confirm that there is no leakage, vacuumize, add refrigerant, and disassemble the drying tank to test the performance of the air conditioning system.
