[0002] Car air conditioning systems, also known as car air conditioners, are used to optimize the temperature, humidity, air cleanliness, and air flow within the vehicle compartment, providing a comfortable ride for passengers and reducing travel fatigue. They also create favorable working conditions for the driver, playing a vital role in ensuring safe driving. These ventilation systems typically include cooling, heating, and ventilation units. These combined systems fully utilize the limited interior space of a vehicle, feature a simple structure, and are easy to operate. They are a popular modern automotive air conditioning system internationally. However, the various components of a car air conditioner are typically installed in various locations throughout the vehicle. These components are connected by air conditioning piping, forming a complete air conditioning system.
