Abstract

An air-conditioning system for air-conditioning a passenger cell with a front region and a rear region may include a housing including an air inlet, a front outlet, a rear outlet, and a footwell outlet. The system may also include an evaporator for cooling an airflow and a heating device for heating the airflow arranged in the housing. A cold air space, a hot air space, a front mixing space, a layering mixing space, and a rear mixing space may be arranged within the housing. The system may also include a front flap configured to control a first connection opening connecting the hot air space to the front mixing space, a layering flap configured to control a second connection opening connecting the hot air space to the layering mixing space, and a rear flap configured to control a third connection opening connecting the hot air space to the rear mixing space.
