How to Check for Leaks in a Car's Air Conditioning System?

[ORiver]

To check for leaks in a car's air conditioning system, you can pressurize it with nitrogen and then apply soapy water for detection. Here is an introduction to air conditioning leak knowledge: 1. Qualitative inspection: Utilize the pressure difference inside and outside the system, amplify the pressure difference through a sensor, and express the leak detection results in the form of numbers, sounds, or electronic signals. This method can only "qualitatively" determine whether the system is leaking but cannot accurately locate the leak point. 2. Hazards: Leaking refrigerant in a car's air conditioning system can be harmful to drivers and passengers. Although refrigerants like Freon are generally low-toxicity or non-toxic, since Freon is fully mixed with refrigeration oil and undergoes frequent temperature changes within the system, refrigerant leakage can still pose certain hazards to human health.
