Is there a relationship between car air conditioning and the water in the radiator?

There is no relationship between car air conditioning and the water in the radiator. Here are specific details about car air conditioning: 1. Introduction: The car air conditioning system (air-conditioning-device), commonly referred to as car AC, consists of components such as the AC compressor, electronically controlled clutch, condenser, and evaporator that form the refrigeration system. 2. Function: It is used to adjust and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to an optimal state, providing passengers with a comfortable riding environment and reducing travel fatigue; it also creates favorable working conditions for the driver and serves as an important ventilation device to ensure safe driving.
As a novice driver who just started driving, I once saw water dripping from the air conditioning on the roadside and suspected it might be a coolant leak. Later, I learned that there's actually no direct connection between them. The car's air conditioning system uses refrigerant circulation for cooling. At the evaporator, it condenses moisture from the car's interior into water droplets, which are then drained outside the chassis. So, it's perfectly normal to see water dripping under the car when using the AC in summer. As for the radiator, it contains antifreeze specifically designed to cool the engine. The liquid circulates in a closed loop between the radiator and the engine, completely separate from the air conditioning system. Sometimes, when people see water droplets in parking lots, they panic, thinking it's a radiator issue, but this is a misunderstanding. During maintenance, these systems should be checked separately. A radiator leak needs immediate repair, while AC water dripping is actually a good sign indicating it's working effectively. It's recommended to regularly check the coolant level and AC cooling performance, but rest assured, the two water systems don't interfere with each other. Don't mix them up.
