Abstract

A method for controlling a refrigeration system of a vehicle includes a circuit containing a refrigerant, a compressor, and first and second evaporators which are connected in parallel to the compressor, and a first expansion valve arranged upstream the first evaporator that regulates a pressure drop of the refrigerant before the first evaporator, and a second expansion valve arranged upstream the second evaporator that regulates a pressure drop of the refrigerant before the second evaporator, and a condenser arranged downstream the compressor between the compressor and the first and second expansion valves. The method includes controlling a total opening of the first expansion valve and the second expansion valve, based on a temperature and a pressure 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.
