Abstract
An air conditioning and heating unit for automotive vehicles includes a blower, an evaporator and a heat exchanger disposed in a synthetic resin housing providing with integral air discharge outlets for the headroom, footroom and center plane of a passenger compartment and for windshield defrosting. The evaporator and the heat exchanger are arranged relative to one another so that the paths of the hot air and of the cold air from the blower to inlet openings of the various air discharge outlets are the same and so that the path of the hot air from the evaporator to the inlet openings is 1.3 to 1.8 times longer than the path of the cold air from the evaporator to the air outlet ducts. The inlet openings of the air outlet ducts emanate from a common chamber in the housing.
