Claim 0:
1. A method for controlling a vapour compression system comprising a compressor unit comprising at least two compressors, a heat rejecting heat exchanger, a receiver, an expansion device and an evaporator arranged in a refrigerant path, the expansion device being arranged to control a supply of refrigerant to the evaporator, at least one of the compressors being a main compressor being fluidly connected to an outlet of the evaporator and at least one of the compressors being a receiver compressor being fluidly connected to a gaseous outlet of the receiver, the method comprising the steps of:
estimating a flow of vapour entering the receiver,
comparing the estimated flow to a first threshold value, and
in the case that the estimated flow is above the first threshold value, controlling a pressure prevailing inside the receiver by operating the receiver compressor.
