How to Tell if a Car's Air Conditioning is Leaking?

[EvanLynn]

Methods to determine if a car's air conditioning is leaking: 1. Inspect the air conditioning pipes and connections for any signs of oil stains; 2. Spray soapy water and check for bubbles, as bubbling indicates a leak. Functions of air conditioning: 1. Achieves cooling effect through the continuous phase change cycle of refrigerant; 2. Removes dust, odors, smoke, and toxic gases from the car's interior, freshening the air, and humidifies the interior air to increase relative humidity; 3. Uses engine coolant, waste heat, or heat generated by a burner as a heat source, which is then heated by a heater and blown into the car's interior or exterior air by a blower to raise the temperature at the air vents for heating purposes; 4. Draws in fresh outside air for ventilation and air exchange, also effectively preventing windshield fogging.
