A method for controlling a vapour compression system (1) including a compressor unit (2) including at least two compressors (3, 12), a heat rejecting heat exchanger (4), a receiver (6), an expansion device (7) and an evaporator (8) arranged in a refrigerant path is disclosed. At least one of the compressors is a main compressor (3) being fluidly connected to an outlet of the evaporator (8) and at least one of the compressors is a receiver compressor (12) being fluidly connected to a gaseous outlet (10) of the receiver (6). A flow of vapour entering the receiver (6), such as a mass flow of vapour entering the receiver (6) is estimated and compared to a first threshold value. In the case that the estimated flow is above the first threshold value, a pressure prevailing inside the receiver (6) is controlled by operating the receiver compressor (12).
A method for controlling a vapour compression system comprising a compressor unit comprising at least two pressors, 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:
