What does 4zone mean in a car?
1 Answers
4zone in a car refers to the air conditioning temperature zoning control, which allows setting different temperatures in different areas of the vehicle to meet various needs. The air conditioning temperature zoning control function provides a more comfortable riding environment for drivers and passengers, as some children or elderly/weakened individuals may not tolerate strong cold air or low temperatures well. Designed for passengers with different temperature requirements, it enables setting different air conditioning temperatures and airflow volumes in various zones of the car. Below are the functions of a car air conditioning system: 1. Temperature regulation: This is the primary function of car air conditioning. In summer, the cooling system generates cold air to lower the cabin temperature; in winter, except for large commercial vehicles that use independent combustion heaters, most vehicles utilize waste heat for heating. 2. Humidity regulation: Humidity significantly affects passenger comfort. Cabin humidity should generally be maintained between 30%-70%. Standard car air conditioners don't have humidity control functions - only through ventilation systems or advanced luxury car integrated heating/cooling systems. 3. Airflow regulation: Airflow velocity and direction greatly impact comfort. When blowing directly, the velocity should be limited within a certain range at appropriate temperatures, and can be adjusted based on passengers' living environments, ages, health conditions, and temperature preferences. 4. Air purification: Cabin air quality is crucial for comfort.
