摘要： An air conditioning control system for an automotive vehicle having an internal combustion engine. A variable capacity compressor has a pump having displacement thereof variable in response to a change in pressure within a controlled pressure chamber, a communication passage communicating between a low pressure chamber and the controlled pressure chamber, and a valve disposed to vary an opening area of the communication passage. An electromagnetic clutch connects and disconnects the compressor to and from the engine. An evaporator is connected to the compressor. A control unit controls the capacity of the compressor by supplying the valve with control current normally set within a predetermined range, to vary the opening area of the communication passage such that the temperature of outlet air from the evaporator becomes equal to a desired value. The control unit supplies the control current having a predetermined value larger than the above predetermined range over a predetermined time period to control the capacity of the compressor to the minimum value, when the electromagnetic clutch is brought into an engaged state from a disengaged state.

摘要： An automobile air-conditioner capable of controlling the displacement of a compressor in view of the traveling condition and air-conditioning condition of an automobile so as to maintain a pleasant feeling of the air-conditioning and an accelerating ability of the automobile in harmony with each other. The air-conditioner includes an air-conditioning preference judgment device by means of which a normal control of the air-conditioning operation is maintained when the judgment of this judgment means indicates the existence of an air-conditioning preference condition. The air-conditioning is performed in preference to acceleration of the automobile depending on the degree of acceleration of the automobile even when the automobile is accelerated.

摘要： Disclosed is an air conditioner for use in an automotive vehicle. The air conditioner includes a timer circuit for deciding whether or not a given period of time has elapsed after an engine of the automotive vehicle has been started, an air quantity controller for limiting the amount of air to be introduced into a passenger compartment for a given period of time after an air cooling operation has been started, a compressor controller for prohibiting the operation of a compressor of the air conditioner for the given period of time to be decided by the timer circuit, a temperature sensor for detecting the temperature of the passenger compartment, and a switch portion for starting the compressor. The timer circuit, the air quantity controller, the compressor controller, and the switch portion are all provided in an air conditioner control unit. The control unit increases the amount of air within the first period of time when the temperature detected by the temperature sensor is greater than a predetermined value and when the switch portion outputs no instruction within the given period of time decided by the timer circuit. Alternatively, the control unit increases the amount of air from within the second period of time longer than the first period of time when the temperature detected by the temperature sensor is greater than the predetermined value and when the switch portion outputs an instruction for starting the compressor within the given period of time decided by the timer circuit.
