Abstract: A demist controller for an automobile air-conditioner includes a demist judgement unit for judging the need for a demist operation based on the relative humidity in the vicinity of the inside surface of a window glass of the automobile, and a correction unit for automatically correcting criteria for a judgement by the judgement unit in accordance with starting and stopping instructions manually given by the driver as occasion arises.

Abstract: An air conditioning control system for an automotive vehicle equipped with windowpanes has a humidity sensor for sensing humidity on the inner surface of a windowpane, and a temperature sensor for sensing temperature of the inner surface of the windowpane. When the sensed humidity on the inner surface is higher than a first predetermined value corresponding to the sensed temperature of the inner surface, the inner surface is determined to be in a state immediately before a mist occurs, and demisting control is executed. A second predetermined value lower than the first predetermined value by a predetermined amount is determined after the start of the demisting control. When the sensed latest value of the humidity on the inner surface becomes lower than the second predetermined value, it is determined that the mist has been cleared away, and the demisting conrol is stopped.

Abstract: In an air conditioning system for vehicles which includes a compressor of a variable capacity type, a comparison is made between a compressor capacity required for an air conditioning control and a compressor capacity required for a demist control. The compressor capacity is controlled so as to be brought to greater one of the compressor capacities compared with each other. Alternatively, when it is judged that a windowpane is misted, the compressor capacity is increased and, simultaneously, the temperature of air blown into the compartment is raised. Alternatively, the compressor capacity is controlled so as to be increased within a range of a set maximum allowable capacity until the mist on the windowpane is cleared off when it is judged that the mist occurs on the windowpane.

Abstract: An air-conditioning equipment for a vehicle includes first and second local shutter control units each having a motor for moving a shutter, a drive circuit for driving the motor, a controlling device responsive to a heat load signal to control the drive circuit to thereby control the shutter in accordance with the heat load signal, and a blower control unit responsive to changes in opening of the shutter to control the rate of an air flow. Since separate shutter control units are provided, each shutter can be controlled independently, thus preventing all the air-conditioning functions from halting simutaneously otherwise occurred in conventional air-conditioning equipment having a central control unit or microcomputer.

Abstract: In an air conditioning system for automotive vehicles, a thermal load on the system is detected, and a desired value of suction pressure of refrigerant gas to a variable capacity type compressor is calculated on the basis of the detected thermal load, in accordance with a predetermined suction-pressure vs. thermal-load characteristic.

A value of torque required for driving the compressor is calculated on the basis of the calculated suction pressure, on the basis of the detected thermal load in accordance with a predetermined required-driving-torque vs. suction-pressure characteristic. Engine rotational speed at idling is set on the basis of the calculated torque value.
