Abstract
A method for controlling a vapour compression system () including a compressor unit () including at least two compressors (), a heat rejecting heat exchanger (), a receiver (), an expansion device () and an evaporator () arranged in a refrigerant path is disclosed. At least one of the compressors is a main compressor () being fluidly connected to an outlet of the evaporator () and at least one of the compressors is a receiver compressor () being fluidly connected to a gaseous outlet () of the receiver (). A flow of vapour entering the receiver (), such as a mass flow of vapour entering the receiver () 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 () is controlled by operating the receiver compressor ().
