    • A method for controlling an opening degree of a valve arranged in a vapour compression system, such as a refrigeration system or a heat pump. The vapour compression system comprises a compressor, a condenser, a valve and an evaporator arranged in a refrigerant flow path. According to a first aspect, the method comprises the steps of obtaining a superheat value for the system and comparing it to a reference superheat value, determining a maximum opening degree of the valve, and controlling the opening degree of the valve in accordance with the comparing step, and in such a manner that the opening degree does not exceed the maximum opening degree. The maximum opening degree is determined dynamically as a function of a mean temperature difference across the evaporator. Thereby the it is ensured that it is possible to open the valve as much as possible, while keeping the operation of the system safe in the sense that the risk that liquid refrigerant is allowed to pass through the evaporator is minimised due to the maximum opening degree. According to a second aspect, an adjustment value is calculated on the basis of the superheat value, the reference superheat value and a generated control signal. Thereby a faster response to changes in the operating conditions for the vapour compression system is obtained.
    • 一种用于控制配置在诸如制冷系统或热泵的蒸气压缩系统中的阀的开度的方法。 蒸气压缩系统包括布置在制冷剂流动路径中的压缩机,冷凝器,阀和蒸发器。 根据第一方面,所述方法包括以下步骤:获得所述系统的过热值并将其与参考过热值进行比较,确定所述阀的最大开度,以及根据所述比较来控制所述阀的开度 并且以使开度不超过最大开度的方式。 最大开度作为蒸发器两端平均温度差的函数动态地确定。 从而确保尽可能地打开阀,同时保持系统的操作安全,因为允许液体制冷剂通过蒸发器的风险由于最大开度而被最小化 。 根据第二方面,基于过热值,参考过热值和产生的控制信号来计算调整值。 从而获得对于蒸汽压缩系统的操作条件的变化的更快响应。

    • A valve part (1), such as a movable part (9) or a stationary part (8) of an actuator for a magnetic valve (7). The valve part (1) has a shading ring (6) made from an electrically conductive material mounted in a groove (3) formed in a surface of the valve part (1). The groove (3) defines a first wall (4, 5) and a second wall (5, 4), the first wall (4, 5) and the second wall (5, 4) extending from the surface into the valve part (1) in such a manner that at least the first wall (4, 5) is inclined relatively to a direction being substantially perpendicular to a substantially plane part (2) of the surface. Furthermore, a method of mounting a shading ring (6) in a valve part (1) comprising the steps of forming a groove (3) as defined above, inserting the shading ring (6) in the groove (3) and deforming the shading ring (6). The inclination of at least one of the walls (4, 5) of the groove (3) ensures a better friction force between the shading ring (6) and the walls (4, 5) of the groove (3). Furthermore, the inclination of one of the walls (4, 5) may be such that the shading ring (6) is mechanically prevented from leaving the groove (3) after it has been inserted therein and deformed. Accordingly, the risk that the shading ring (6) leaves the groove (3) is decreased.
