Abstract

A method for controlling a vapour compres sion system (1) during start-up is disclosed. The rate of True change, ∆Ti , of the temperature of refrigerant entering the True evaporator (4), and the rate of change, ∆T2, of the temperat ure of refrigerant leaving the evaporator (4) are compared. Based on the comparing step, a refrigerant filling state of the evaporator (4) is determined. The opening degree ( 11) of the expansion device (3) is then controlled according to a first control strategy in the case that it is determined that the evaporator (4) is full or almost full, and according to a second control strategy in the case that it is determined that the evaporator (4) is not full. Thereby it is ensured that a maximum filling degree of the evaporator (4) is quickly reached, without risking that liquid refrigerant passes through the evaporator (4).
