Control method of an electric air conditioning compressor and air conditioning system implementing such a control method

摘要

Method for controlling an electric air conditioning compressor and air conditioning system implementing such a control method The present invention relates to a method (8) for controlling an electric air conditioning compressor (2) for a motor vehicle, comprising : a step (E3) for calculating the compression ratio TC, a step (E4) for calculating a setpoint value VC as a function of a suction pressure PA of said compressor, a step (E5) for comparing the rate compression TC with the setpoint VC, if the compression ratio TC is equal to the setpoint VC, the method (8) further comprises: a step (E6) of modulating the speed of rotation of said compressor (2 ) and / or the opening of an electronic expansion valve.
