Abstract:
An air-conditioning system for an engine-driven motor vehicle comprising:an evaporator for providing cold air; a heater located downstream of the evaporator for generating warm air heated by coolant from the motor vehicle engine, said heater having at least one partition dividing the air-conditioning system downstream of the evaporator into at least two regions arranged next to one another; a cold-air bypass duct guided past the heater in each of said regions; a regulator system for regulating the temperature of the coolant in the heater for bringing the entire heater to a predetermined temperature, whereby air flowing through the heater is controlled to a maximum temperature that is dependent on the temperature of the heater and that corresponds to an air temperature desired in a first interior zone of the vehicle; and an air control element in at least one of said bypass ducts for selectively bypassing cold air in at least one of said regions to lower the temperature of the air that is to be introduced into a second interior zone of the vehicle.
