Abstract

Apparatus for heating and ventilating vehicle compartments. For temperature control, two parallel ducts are provided. A heat exchanger is located in only one of the ducts. A separate blower is associated with each of the ducts, whereby the speed of both blowers is adjustable simultaneously, and inversely proportional, via an actuating element. A mixture of cold and warm air is possible in this manner within the mixing chamber, whereby a sensitive temperature control can be obtained.
