Abstract

An air conditioner for a vehicle has a heater core for heating air blown from upstream thereof and discharging the heated air downstream thereof. An air passage is arranged in parallel with the heater core, and the air flow through the heater core and the air passage is controlled by a rotatable damper. A first chamber is provided downstream of the heater core and air passage for mixing the heated air from the heater core with non-heated air from the air passage. A second chamber is provided downstream of the first chamber for distributing the mixed air to a ventilation diffuser and/or to a third chamber. The third chamber can distribute the air alternatively to a defroster or a heater diffuser. Closable bypass passages are provided directly connecting the discharge end of the heater core with the third chamber, so that extra heated air may be moved directly to the third chamber when desired, thereby allowing the passenger to have cool air around his head and heated air around his legs.
