Why does water drip from the chassis when the car's air conditioning is on?
2 Answers
It is normal for water to drip from the chassis when the car's air conditioning is on, as the air conditioning drain outlet is usually located beneath the chassis. Below is an introduction to the car's air conditioning system: 1. Overview of car air conditioning: The car air conditioning system (air-conditioning-device), commonly referred to as car AC, is designed to regulate and control the temperature, humidity, air cleanliness, and airflow within the car cabin to optimal conditions. It provides a comfortable environment for passengers, reducing travel fatigue, and creates favorable working conditions for the driver, playing a crucial role in ensuring safe driving as a ventilation device. 2. Components of car air conditioning: Generally, it includes a refrigeration unit, heating unit, and ventilation unit. This integrated system makes full use of the limited space inside the car, featuring a simple structure and ease of operation, making it a popular modern car air conditioning system internationally.
It's actually quite normal for the chassis to drip water when using the air conditioning in summer. I believe this is an inevitable phenomenon of the AC system working. When the cold air is on, the hot air inside the car passes through the evaporator and gets cooled, causing the moisture in the air to condense into water droplets. These droplets are then drained out from under the chassis through a component called the drain pipe, preventing water accumulation inside the AC system which could lead to mold or odors. I've encountered some people mistakenly thinking their car was broken, but as long as the dripping occurs on the ground near the front tires and not inside the car, there's no issue. If you notice too little or no dripping, the drain pipe might be clogged and need cleaning; otherwise, water could back up, causing internal flooding and foul odors. Regularly checking the dripping situation after parking can help avoid unnecessary repair costs.
