    Abstract: 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.

    Abstract: An air handling system (1) for a land transport vehicle, in particular a railway vehicle (M) is disclosed. The system includes: one or more air handling units (2) distributed within the vehicle (M); a cooling machine (4) that supplies frigories to the air handling units; and a frigories storage unit (8) that is capable of being loaded by the cooling machine and of supplying frigories to the air handling units when the vehicle is travelling in an enclosed or partially enclosed space. When the vehicle (M) is travelling in the open air, the cooling machine (4) supplies frigories to the air handling units (2) and loads the frigories storage unit (8) if a surplus of frigories is produced, by discharging into the exterior of the vehicle (M) the heat extracted from an interior volume of the vehicle.
