In an apparatus for controlling blowing mode of a car air-conditioner, a position of a shutter for changing the blowing mode is continuously changed in accordance with a control signal which depends upon at least the air temperature outside car. The control signal is applied to the actuator to position the shutter at an appropriate position in response to the ambient conditions.

Apparatus for controlling blowing mode of a car air-conditioner

An automotive air conditioning apparatus is provided which, in raising the temperature inside a vehicle cabin from a low level to a preset higher level in a maximum cooling mode or in lowering the cabin temperature from a high level to a preset lower level in a maximum heating mode, suitably controls in an initial stage of the procedure the revolution speed of a blower but does not drive an air mix door at all to keep it at an existing opening degree. When the revolution speed of the blower reaches a predetermined lowest speed, the air mix door begins to be driven to vary its opening degree progressively and suitably while, at the same time, a first reference temperature level for deactivating a compressor associated with a cooler is shifted to a second reference temperature level.

Vehicle temperature control apparatus

In an apparatus for controlling the speed of the blower motor in response to the difference between the temperature setting and the temperature inside the vehicle, the maximum speed of the blower motor is limited in accordance with the temperature of engine coolant. Consequently, the quantity of air issuing from the blower is always such that it does not make the passengers feel uncomfortable.
