Why does the car air conditioning pipe freeze but the air blown out is not cool?

If the car air conditioning pipe freezes but the air blown out is not cool, it may be due to issues with the quality and purity of the refrigerant, faults in the condenser and radiator, problems with refrigerant usage, or quality issues with the expansion valve. Below are some troubleshooting methods: Comprehensive component inspection: Check if the air conditioning is blocked or damaged; check if the condenser surface is contaminated with oil or leaking; check if the radiator is leaking. Internal fluid inspection: Verify if the coolant level is normal and if it is turbid; if the antifreeze's pH is below 7.5, it is too acidic and can easily damage the metal in the radiator; if the pH is above 9, it is too alkaline, which can cause the corrosion inhibitor to precipitate and lose its anti-corrosion effect.
