Abstract
A vehicle cooling system may include a variable displacement compressor, and a controller configured to, in response to a determination that the compressor is operating within a gurgling zone that is defined by a predefined range of compressor speeds and currents, generate a current signal defining a displacement for the compressor based on a speed of the compressor and an ambient temperature to control the displacement to reduce refrigerant flow noise.
