Abstract
An air conditioning system including main and auxiliary cooling units for air conditioning the inside of an automotive vehicle has a compressor, variable in discharge volume, for discharging a compressed refrigerant to the main and auxiliary cooling units. The compressor is controlled to vary its discharge volume, according to a thermal loading on the vehicle, so as to provide conditioning air cooled by the main cooling unit to a desired temperature according to the thermal load. When a demand for cooling from the auxiliary cooling unit is greater than a demand for cooling from the main cooling unit, the compressor is controlled to vary its discharge volume according to the demand for cooling from the auxiliary cooling unit, and vice versa.
