ABSTRACT:
An air conditioning apparatus for cars comprises an air intake fan having internal and external air inlet ports; a heat exchanger for cooling and a heat exchanger for warming, both being arranged in series at the downstream of the intake fan and in the direction substantially perpendicular to the direction of the air flow; an air mixing chamber formed at the downstream of the heat exchanger for warming, the air intake fan having the internal and external air inlet ports, the heat exchanger for cooling, the heat exchanger for warming and air mixing chamber being all installed in one and the same casing in the order. The area of ventilation of the heat exchanger for warming is smaller than that of the heat exchanger for cooling; a by-pass route is formed in the casing and an air mixing damper is positioned in the by-pass route to regulate the flow rate of cooling air, the air mixing damper being operated in association with a warm water valve for regulating the flow rate of warm water supplied to the heat exchanger for warming.
