Air conditioning apparatus for conditioning the air supplied to a vehicle passenger space is provided which includes an air conditioning air cooling evaporator and an air heater unit arranged in series. An evaporator bypass duct extends in bypassing relationship to the evaporator and a heater bypass duct extends in bypassing relationship to the heater. To control the temperature of the air conditioned by the apparatus two temperature mixing air flaps are provided, one air flap controlling the proportion of air flow through the evaporator and its bypass duct and the other air flap controlling the proportion of air through the heater and its bypass duct.
