Method for checking the refrigerant-fluid level of a closed loop vehicle air-conditioning system
A signal value is derived that is representative of the cooling power produced by an air-conditioning evaporator, the signal value being derived from at least one temperature sensor placed in thermal contact with the evaporator, or downstream from it in the cooled airflow, and the signal value is compared with a reference value corresponding to a normal refrigerant-fluid level. A signal value below the reference value indicates a low level of refrigerant-fluid.
