Abstract
An improved method of operation for a vehicle air conditioning system controls an inlet air blower motor and an air inlet mixing device to reduce compressor and blower motor power consumption and achieve performance improvements associated with cabin air recirculation while maintaining a predefined level of outside air flow and a predetermined humidity level in the inlet air mixture of the system. The overall air flow is determined by the speed of the blower motor and the speed of the vehicle, and the speed of the blower motor and the position of the inlet air mixing device are adjusted as a function of both the vehicle speed and the selected blower motor speed so that the predefined level of outside air flow is preserved regardless of the vehicle speed and the selected blower motor speed.
