The invention relates to a system and method for regulating an air-conditioning unit. More specficially, the invention relates to a frequency control regulation system for a compressor, which is used to optimise power consumption in a motor vehicle air-conditioning unit comprising a cooling circuit (1) which is equipped with an electric compressor (2), the rotation frequency thereof being controlled according to a set value. The inventive system comprises a means (8, 9, 10, 17) for measuring one or more physical parameters in the cooling circuit and a processing means (20) for calculating at least one value from the measured parameters. The calculated value represents a change in the capacity to cool the temperature of the air flow in relation to the power absorbed by the compressor. The aforementioned processing means (20) compares the calculated value with one or more threshold values and a frequency control means (13) for the compressor, which is connected to the processing means (20), adjusts the rotation frequency of the electric compressor according to the result obtained from said comparison. |
