摘要： A method for operating a vapour compression system (1) is disclosed. The vapour compression system (1) comprises a compressor (2), a condenser (3), at least one expansion device (4), an evaporator (5), said evaporator (5) comprising at least two evaporator paths (5a, 5b) arranged fluidly in parallel, and a distribution device arranged to distribute refrigerant among the evaporator paths (5a, 5b). The method comprises the steps of obtaining at least two predefined distribution keys, each distribution key defining a distribution of available refrigerant among the evaporator paths (5a, 5b), detecting one or more operational settings of the vapour compression system (1), selecting one of the at least two predefined distribution keys, based on said detected operational setting(s), and distributing refrigerant among the evaporator paths (5a, 5b) in accordance with the selected predefined distribution key. The predefined distribution keys constitute pre-settings which can be selected on the basis of operational settings, such as compressor capacity, fan speed, refrigeration load or mode of operation. The vapour compression system (1) may be operated in accordance with the selected predefined distribution key, or the selected predefined distribution key may be used as a suitable starting point for an adaptive adjustment of the distribution key. An optimal distribution of the available refrigerant among the evaporator paths (5a, 5b) is quickly reached due to the pre-settings. Thereby the vapour compression system (1) can be operated in an optimal manner for most of the operating time.
