Abstract

Disclosed is a motor vehicle air-conditioning system in which individual air-conditioning zones can be air-conditioned independently. The air-conditioning system is divided into four partial regions by partitions. In order to provide as small a construction space as possible as well as simple regulation, the coolant stream through the heater (22) is regulatable, in order to bring the entire heater (22) to a specific temperature. Thus, air flowing through the heater (22) can be controlled to a maximum temperature dependent on the temperature of the heater (22), corresponding to the (warmest) air temperature desired in one of the interior zones (HL, VL, VR, HR). In the other region(s) (B1, B2, B3, B4) of the air-conditioning system (10), the temperature of the air to be introduced into the other interior zone(s) (HL, VL, VR, HR) can be lowered by means of cold air guided via a bypass (32R, 62R).
