Abstract
A method for controlling a vapour compression system () is disclosed, the vapour compression system () comprising at least one expansion device () and at least one evaporator (). For each expansion device (), an opening degree of the expansion device () is obtained, and a representative opening degree, OD, is identified based on the obtained opening degree(s) of the expansion device(s) (). The representative opening degree could be a maximum opening degree, OD, being the largest among the obtained opening degrees. The representative opening degree, OD, is compared to a predefined target opening degree, OD, and a minimum setpoint value, SP, for a pressure prevailing inside a receiver (), is calculated or adjusted, based on the comparison. The vapour compression system () is controlled to obtain a pressure inside the receiver () which is equal to or higher than the calculated or adjusted minimum setpoint value, SP.
