How to Deal with Clogged Car Air Conditioning Pipes?
1 Answers
Methods for dealing with clogged car air conditioning pipes are as follows: Open the system pipes and repeatedly blow them with high-pressure gas, replacing some components if necessary. Blockages in the air conditioning system pipes mostly occur at the electronic expansion valve, capillary tube, throttle valve core, and other parts, which are generally equipped with dry filters. When it is confirmed that the system pipes are clogged with dirt, the system pipes should be opened, preferably at both the throttle component and possible flare connection points simultaneously. Use high-pressure gas or the same refrigerant to repeatedly blow through each section of the pipe in both forward and reverse directions, then replace the capillary tube and dry filter. If it is an electronic expansion valve, power it to activate. A dirty blockage in the air conditioning system may be accompanied by deteriorated refrigeration oil, and the process of releasing the refrigerant will naturally lose some refrigeration oil. Therefore, after cleaning the pipes, add an appropriate amount of refrigeration oil to the air conditioning system pipes. Excessive refrigerant can cause noise during operation, and bubbles can be observed in the sight glass, with high and low-pressure gauge readings being too high. Release the excess refrigerant until the gauge readings drop to standard values and the bubbles disappear.
