Abstract

The invention concerns a motor vehicle air conditioning unit equipped with an air conditioning system (10) and an electronic control device (401). The unit further comprises a device for estimating the mass flow rate of a refrigerant in the system, first estimating means (25) for supplying a value concerning air temperature at the evaporator input, second estimating means (26) for supplying a value concerning air temperature at the evaporator output (13). The electronic control device is adapted to detect atmospheric moisture at the evaporator input (13) based on the value supplied by the device estimating the refrigerant mass flow rate, and on the values supplied by the first and second estimating means.
