Abstract
An air-conditioning system for motor vehicles having an evaporator and a heat exchanger arranged successively in the air flow. A separate air duct having an air outlet opening for the central jet, is connected on the one hand via a cold-air opening to an air-chamber upstream of the heat exchanger and, on the other hand, via a hot-air opening to an air chamber downstream of the heat exchanger. The cross-section of the bypass openings can be controlled by bypass flaps which are coupled with actuators. A control unit with stored characteristics is provided which indicate the correlation between the air quantity and air temperature of the air issuing at the central jet and the position of the bypass flaps. The control unit applies actuation values to the actuators, which actuation values effect a setting of the bypass flaps redetermined by characteristics for a preselected air quantity and air temperature.
