At idle a variable displacement compressor is hardly pumping any refrigerant (AKA Freon) so there is less load on the engine. When the engine is revved up or at high rpm the the variable displacement compressor knows this so it increase the displacement in the compressor by varying the angle of the rotor that is used to move the pistons. This increase in displacement allows more refrigerant to be pumped through the system which in turns create a greater cooling effect (AKA Air Conditioning).
