A METHOD FOR CONTROLLING A REFRIGERATION SYSTEM OF A VEHICLE

The invention relates to a method for controlling a refrigeration system (1) of a vehicle. The refrigeration system comprises a circuit (2) containing a refrigerant, a compressor (3), and a first evaporator (4) and a second evaporator (5) which are connected in parallel to the compressor, and a first expansion valve (9) arranged upstream the first evaporator, which first expansion valve regulates a pressure drop of the refrigerant before the first evaporator, and a second expansion valve (10) arranged upstream the second evaporator, which second expansion valve regulates a pressure drop of the refrigerant before the second evaporator, and a condenser (11) arranged downstream the compressor (3) between the compressor and the first and second expansion valves. The method comprises controlling a total opening of the first expansion valve (9) and the second expansion valve (10), based on a temperature (Tm) and a pressure (pm) of the refrigerant which refrigerant temperature and refrigerant pressure are measured downstream the first and second evaporators at a position between the first and second evaporators and the compressor.
