Is It Normal for Water to Leak Under the Chassis After Turning on the Car Air Conditioner?
2 Answers
It is normal for water to leak under the chassis when the car's air conditioner is turned on. This is related to the working principle of the air conditioner. Below is the relevant introduction: Car Air Conditioner: The car air conditioning device (air-conditioning-device), referred to as car air conditioner, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state, providing a comfortable riding environment for passengers and reducing travel fatigue. Air Conditioner Layout: Different types of air conditioning systems have different layout methods. Currently, integrated heating and cooling air conditioning systems are widely used in passenger cars. The layout involves assembling components such as the evaporator, heater radiator, centrifugal blower, and control mechanism together, known as the air conditioner assembly.
It is usually normal for water to leak from under the car after driving with the air conditioning on and then parking. As someone who frequently drives long distances, I notice that every summer after using the air conditioning, water drips from the center of the car's undercarriage. This water is condensation produced by the air conditioning system during dehumidification, where moisture from the air condenses into water droplets and drains out through designed drainage holes. The water is clean, clear, and odorless, just like the water that drips from a home air conditioner. However, there are a few things to note: The water should drip from the front or middle of the chassis. If it's leaking near the engine or has color or odor, it might indicate coolant leakage or oil line issues. The flow rate should normally be a slow drip; if it's gushing or spraying, check for a blocked drainage hole. In short, this is normal during summer or humid weather, and there's no need to panic.
