Car air conditioning systems operate based on the following principle: They output control signals according to the temperature inside the vehicle, evaporator temperature, engine coolant temperature, and other relevant switch signals detected by various sensors. These signals control the operational states of components such as the radiator fan, condenser fan, compressor clutch, blower motor, and air control motor to achieve automatic regulation of the cabin temperature. Composition and functions of a car air conditioning system: The system consists of a refrigeration system, heating system, air purification device, and control system. Its purpose is to adjust and maintain the temperature, humidity, air cleanliness, and airflow within the passenger compartment at optimal levels, providing occupants with a comfortable environment, reducing travel fatigue, creating favorable working conditions for the driver, and ensuring driving safety.

How many days does it take for water accumulated in the chassis to dry under sun exposure?

It takes about three days of sun exposure for the soundproofing cotton in the chassis to dry completely after being soaked. Check the following factors: whether the sealing strips are aged, cracked, or incomplete, leading to poor sealing and water ingress; whether the waterproof membrane is damaged—inspect the waterproof membrane inside the rear door trim panel and recall if any repairs or modifications were previously done that might have affected the membrane; whether the drainage holes on both sides of the sunroof are clogged—if blocked, rainwater cannot drain through the pipes, causing the water level to rise continuously until it overflows along the headliner and sealing strips, eventually soaking the soundproofing cotton on the floor panel.
