A process for supervising an air conditioning system of a railway vehicle. The process comprising the following steps: a) after starting the air conditioning system, measuring physical properties relative to the refrigerant; b) from the physical properties measured during step a), calculating thermodynamic properties; c) from the thermodynamic properties calculated during step b), calculating the density, optionally averaged, of the refrigerant inside each component of the air conditioning system; d) using manufacturer data, which includes the dimensions of each component of the air conditioning system, calculating the passage volume of the refrigerant inside each component of the air conditioning system; e) using the values calculated in steps c) and d) to calculate the total mass of refrigerant contained inside the air conditioning system; and f) comparing the total mass of refrigerant calculated in step e) with the total mass of refrigerant originally contained inside the air conditioning system.
