Abstract
The vapour compression system includes a compressor unit having at least one main compressor and at least one receiver compressor, a heat rejecting heat exchanger, a receiver, an expansion device and an evaporator being arranged in a refrigerant path. The vapour compression system further includes a bypass valve fluidly interconnecting the gaseous outlet of the receiver and the main compressor(s). An opening degree of the bypass valve is controlled to regulate the pressure prevailing in the receiver in accordance with a first pressure setpoint when a load demand of the vapour compression system exceeds a maximum capacity of the receiver compressor(s). The opening degree of the bypass valve is controlled to regulate the pressure prevailing in the receiver in accordance with a second pressure setpoint when the receiver compressor(s) is/are operating and the load demand of the vapour compression system is below the maximum capacity of the receiver compressor(s).
