Abstract: An expansion valve (4) for a vapour compression system (1), and a vapour compression system comprising such an expansion valve (4) are disclosed. The expansion valve (4) comprises a first valve member (7) and a second valve member (8). The first valve member (7) and the second valve member (8) are arranged movably relative to each other, and the relative position of the first valve member (7) and the second valve member (8) determines an opening degree of the expansion valve (4). The first valve member (7) and/or the second valve member (8) is/are automatically movable in response to changes in a differential pressure across the expansion valve (4), the opening degree of the expansion valve (4) thereby being automatically altered in response to changes in the differential pressure across the expansion valve (4). It is ensured that the opening degree of the expansion valve (4) is automatically adjusted to the actual operating conditions, thereby optimising the efficiency of the vapour compression system (1). Furthermore, this is obtained in a simple manner, without requiring complicated control of the valve (4).

Abstract: 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.
