Document Type and Number:
WIPO Patent Application WO/2022/222824
Kind Code:
A1
Abstract:
A method for controlling a refrigeration system (1) of a vehicle is provided. The refrigeration system (1) 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 (3), and a first expansion valve (9) arranged upstream the first evaporator (4), which first expansion valve (9) regulates a pressure drop of the refrigerant before the first evaporator (4), and a second expansion valve (10) arranged upstream the second evaporator (5), which second expansion valve (10) regulates a pressure drop of the refrigerant before the second evaporator (5), and a condenser (11) arranged downstream the compressor (3) between the compressor (3) and the first and second expansion valves (9,10), controlling a total opening of the first expansion valve (9) and the second expansion valve (10), based on a temperature and a pressure of the refrigerant which refrigerant temperature and refrigerant pressure are measured downstream the first and second evaporators (4,5) at a position between the first and second evaporators (4,5) and the compressor (3).
