Abstract
A method for controlling a vapour compression system () is disclosed, the vapour compression system () comprising at least one compressor (), a heat rejecting heat exchanger (), a high pressure expansion device (), a receiver (), an evaporator expansion device (), an evaporator () and a gas bypass valve (), arranged in a refrigerant path. It is registered that the gas bypass valve () is malfunctioning or saturated, and a pressure value for a pressure prevailing inside the receiver () is obtained. Finally, the vapour compression system () is controlled in order to control a gaseous refrigerant supply to the receiver () to adjust the pressure prevailing inside the receiver () to reach a target pressure level.
