What Causes the Low-Pressure Pipe of a Car's Air Conditioning to Overheat?

[LunaRose]

There are several reasons why the low-pressure pipe of a car's air conditioning may overheat: 1. The evaporator is clogged, refrigerant flow is insufficient, or the pipeline pressure is too high. 2. Excessive dirt buildup on the condenser's copper pipes/fins reduces heat exchange efficiency. 3. Malfunctions in the compressor or expansion valve can also cause this issue. Here are some solutions for an overheating low-pressure pipe in a car's air conditioning: 1. Check if the air conditioning evaporator is clogged and clean any debris. 2. If the low-pressure pipe overheats due to a refrigerant leak, locate and repair the leak before refilling the refrigerant to restore normal operation. 3. Poor heat dissipation from the air conditioning condenser can also lead to inadequate cooling performance, so cleaning the condenser is necessary.
