    Abstract: A vapour compression system (1) comprising at least two evaporator groups (5a, 5b, 5c), each evaporator group (5a, 5b, 5c) comprising an ejector unit (7a, 7b, 7c), at least one evaporator (9a, 9b, 9c) and a flow control device (8a, 8b, 8c) controlling a flow of refrigerant to the at least one evaporator (9a, 9b, 9c). For each evaporator group (5a, 5b, 5c) the outlet of the evaporator (9a, 9b, 9c) is connected to a secondary inlet (12a, 12b, 12c) of the corresponding ejector unit (7a, 7b, 7c). The vapour compression system (1) can be controlled in an energy efficient and stable manner. A method for controlling the vapour compression system (1) is also disclosed.

    Abstract: A vapour compression system (1) comprising a compressor unit (2), a heat rejecting heat exchanger (4), an ejector (5), a receiver (6), an expansion device (7) and an evaporator (8) is disclosed. The vapour compression system (1) further comprises a non-return valve (9) arranged in the refrigerant path between an outlet (17) of the evaporator (8) and an inlet (15) of the compressor unit (2). The outlet (17) of the evaporator (8) is connected to a secondary inlet (16) of the ejector (5) and to the inlet (15) of the compressor unit (2), via the non-return valve (9), and a gaseous outlet (12) of the receiver (6) is connected to a part of the refrigerant path which interconnects the non-return valve (9) and the inlet (15) of the compressor unit (2). The non-return valve (9) ensures automatic control of refrigerant flow from the evaporator (8) towards the compressor unit (2) and the secondary inlet (16) of the ejector (5), and from the receiver (6) towards the compressor unit (2).

    Abstract: A method for controlling a valve arrangement (12), e.g. in the form of a three way valve, in a vapour compression system (1) is disclosed, the vapour compression system (1) comprising an ejector (6). The valve arrangement (12) is arranged to supply refrigerant to a compressor unit (2) from the gaseous outlet (11) of a receiver (7) and/or from the outlet of an evaporator (9). The vapour compression system (1) may be operated in a first mode of operation (summer mode) or in a second mode of operation (winter mode). When operated in the second mode of operation, it is determined whether or not conditions for operating the vapour compression system (1) in the first mode of operation are prevailing. If this is the case, the valve arrangement (12) is actively switched to the first mode of operation by closing a first inlet (13) towards the evaporator (7) and fully opening a second inlet (14) towards the receiver (7).
