What does 3-zone mean for car air conditioning?

[IsabelleLynn]

3-zone refers to the three-zone control mode of the air conditioning system. When the switch light is on, it indicates that the rear air conditioning is controlled by the rear control panel. When the switch light is off, it means all air conditioning is uniformly controlled. Below is an introduction to 3-zone: 1. Working principle: The 3-zone climate control system works by adding additional air flaps to divide the air ducts more finely. After passing through the mixing flaps, air is directed to different ducts, with the mixing flaps controlled by multiple independent controllers. 2. Notes: A car may have rear air vents but not necessarily rear temperature zone control. Temperature zone control is based on automatic air conditioning systems. Some models may be equipped with automatic air conditioning but cannot achieve independent rear air conditioning control.
