Air conditioner control arrangement for automotive vehicle or the like

摘要

The blower of an air conditioner is either (a) rotated at an ultra low speed until a first predetermined air temperature is sensed in the duct in which the blower is disposed, or (b) is temporarily disabled until a minimal engine coolant temperature is sensed, whereafter in both cases the rotational speed of the blower is stepped up a little to a still "low" level and held at this level until the temperature of the air discharged from the duct has risen to a second predetermined temperature. Subsequently the rotational speed of the blower is increased at a suitable rate until a maximum rotational level is reached.
