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. The suction pressure is controlled on the basis of the calculated desired suction-pressure value. 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.
