    Abstract: A method for controlling a vapour compression system (1) comprising two or more evaporators (5, 12), each evaporator (5, 12) being arranged in thermal contact with a refrigerated volume, and each evaporator (5, 12) receiving refrigerant via an expansion device (6, 13) is disclosed. In response to receipt of a load shedding command originating from a power grid (17), the vapour compression system (1) reduces a compressor capacity of the compressor unit. The refrigerated volumes are divided into at least two prioritized categories of refrigerated volumes, where a first category (18) includes refrigerated volumes with temperature critical storage, and a second category (19) includes refrigerated volumes with temperature non-critical storage. Refrigerant supply to the evaporator(s) (5, 12) being in thermal contact with the refrigerated volume(s) of the second category (19) is discontinued, and refrigerant supply to the evaporator(s) (5, 12) being in thermal contact with the refrigerated volume(s) of the first category (18) is continued. Thereby the vapour compression system (1) is capable of providing load shedding services for an extended period of time without compromising temperature critical storage.

    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.

    Abstract: An expansion valve (1) comprising an inlet opening and at least two outlet openings (5) is disclosed. The inlet opening is adapted to receive fluid medium in a liquid state, and the outlet openings (5) are adapted to deliver fluid medium in an at least partly gaseous state. The expansion valve (1) further comprises a diaphragm (6), and at least two valve seats (4), each valve seat (4) being fluidly connected to one of the outlet openings (5). Each of the valve seats (4) forms a valve in combination with the diaphragm (6), the position of the diaphragm (6) thereby simultaneously defining an opening degree of each of the valves. A well defined distribution of fluid flow towards each of the outlet openings (5) is easily defined by movements of the diaphragm (6). The distribution takes place before or during expansion of the fluid medium. The expansion valve (1) may be arranged in an refrigerant path of a refrigeration system.
