    Abstract: A method for controlling a flow of refrigerant to an evaporator (1) arranged in a refrigeration system is disclosed. The refrigeration system further comprises an expansion valve (12) and a compressor, the expansion valve (12), the evaporator (1) and the compressor being arranged in a refrigerant flow path having refrigerant flowing therein. The method comprises the steps of increasing an opening degree of the expansion valve (12), thereby increasing a flow of refrigerant to the evaporator (1) sufficiently to substantially eliminate a dry zone (3) of the evaporator (1), decreasing the opening degree of the expansion valve (12) after a period of time has lapsed, and repeating the steps of increasing and decreasing the opening degree of the expansion valve (12). Thus, the opening degree of the expansion valve (12) is 'pulsated'. This causes the superheat value of refrigerant leaving the evaporator (1) to 'toggle' between a zero level and a low, but positive, level. Thereby the average superheat value of the refrigerant leaving the evaporator (1) is decreased, and the refrigeration capacity of the evaporator (1) is utilised more efficiently. Simultaneously, it is ensured that the amount of liquid refrigerant being allowed to pass through the evaporator (1) is kept sufficiently low to prevent damage to the compressor.

    Abstract: The invention provides a method of controlling a release of thermal energy in a building. The method comprises steps of defining a control criterion for the building, defining a set of climate variables which influence the release of thermal energy in the building, and defining for each climate variable, a climate signification index which defines the importance of that climate variable for the release of thermal energy in the building. Furthermore, the method comprises a step of receiving a set of predicted future climate variables, and subsequently a step of combining the climate signification indices and the predicted future climate variables to provide control instructions for release of an amount of thermal energy in the building to satisfy the control criterion. The invention further provides a comfort control system.

    Abstract: A magnetic actuator (1 ) comprising a stationary part (3), a movable part (4) and a coil (10) arranged circumferentially relatively to the movable part (4) in such a manner that the movable part (4) is moved relatively to the stationary part (3) in response to a magnetic field induced when an electrical current runs in the coil (10). The stationary part (3) and the movable part (4) are shaped in such a manner that one is provided with a protruding part (5) and the other is provided with a recess (6) adapted to receive the protruding part (5). Thereby the minimum distance between the stationary part (3) and the movable part (4) are kept relatively low, and it is thereby possible to obtain a large pulling force without increasing manufacturing costs. The actuator (1 ) further comprises a shading ring (7) providing a magnetic field having a phase which is different from the phase of the field induced by the coil (10). This prevents the movable part (4) from repeatedly hitting the stationary part (3) and makes the actuator (1 ) suitable for use in AC as well as DC applications. The actuator (1 ) is suitable for use in a magnetic valve (9).
