摘要： The present invention refers to an air conditioning unit (1), in particularly for buildings. The inventive air conditioning unit preferably comprises at least an air conditioning means for heating and/or cooling of air, wherein the air conditioning means comprises a functional fluid and functional means (8, 10), in particular a condenser means (8) for condensing said functional fluid or an evaporator (10) for evaporating said functional fluid or a heat-exchanger for transferring thermal energy from the functional liquid to the surrounding or vice versa, a frost detection means (2) for detecting ice or snow inside or at the outside of the functional means, wherein the frost detection means (2) comprises at least one conductor element (41) for conducting electric energy from a source (70) to an electric energy conducting part (71) of the functional means (8, 10), wherein the conductor element (41) is arranged spaced apart and in close vicinity, in particularly less distance than 10mm, to the electric energy conducting part (71) of the functional means (8, 10), wherein the conductor element (41) and the electric energy conducting part (71) become short-circuited due to growth of ice or snow, and a current measurement and/or detection unit (60) for measuring and/or detecting current flow via the conductor element (41), wherein the measurement and/or detecting unit (60) triggers defrosting in dependency of the measured and/or detected current flow.

摘要： There is provided an inductor (5) having a coil (10) enclosing at least a part of a core (15, 20, 70, 90). A sensor (40) senses a current when flowing in the coil (10). The core comprises a first part (15), and a second part (20, 70, 90) comprising a movable metal part mounted relative to the first part (15) of the core such that the second movable metal part (20, 70, 90) is separated from the first part (15) of the core by an air gap (25, 30). A least a portion of the second part (20, 70, 90) is arranged to move relative to the first part (15), thereby to vary the magnetic permeability of the core (15, 20, 70, 90), according to an output of the sensor (40). In this way, if the output of the sensor (40) indicates an onset of saturation of the core (15, 20, 70, 90), the magnetic permeability of the core (15, 20, 70, 90) may be reduced by such movement. A method for varying the magnetic permeability of an inductor core (15, 20, 70, 90) is also provided.

摘要： The present invention provides a method of controlling a permanent magnet motor (101). The permanent magnet motor may be a brushless direct-current (BLDC) motor or a permanent magnet synchronous motor (PMSM). The method comprises applying closed-loop control (301) to the speed of the motor to match it to a reference speed (ω ref ) by comparing a measured q-axis stator current of the motor with a reference q-axis stator current of the motor and deriving a difference therebetween. This difference represents the current error. The current error is compared (302) to a threshold value at which a phase current amplitude of the motor starts to exhibit distortions. If the current error is not greater than this threshold value, the reference speed (ω ref ) of the motor is set (303) equal to an application reference speed of the motor for its particular application and the closed-loop control is continued. If, on the other hand, the current error is greater than the threshold value, the reference speed (ω ref ) is set (304) equal to a temporary reference speed, which is then compared (305) to the application reference speed. If the temporary reference speed is not less than the application reference speed, the reference speed (ω ref ) is set (306) equal to the application reference speed and the closed-loop control is continued. If, on the other hand, the temporary reference speed is less than the application reference speed, a phase offset angle (theta) between stator and rotor magnetic fields of the motor is changed (307), in order to adjust the actual speed of the motor by flux weakening, before the closed-loop control continues. In this way, the actual speed of the motor may be made to approach the reference speed (ω ref ) without inducing periodical variations in the amplitude of the motor phase current waveform. The invention also provides a system for performing such a method and computer program product or a program code for executing such a method.
