Definitions

  • the present invention relates to a method for operating a linear compressor, in particular for a refrigeration device.
  • a linear compressor is eg off US 6506032B2 Next state of the art and US 6641377B2 known. It comprises a reversing linear drive with a winding and an armature displaceable by a magnetic field generated by the winding against a spring force and a compression chamber in which a piston is coupled to the armature movable.
  • the winding is subjected to an alternating current in order to drive a swinging motion of the armature.
  • the amplitude of movement of the piston is strictly predetermined, this is not the case with a linear compressor.
  • the armature can oscillate with different amplitudes depending on the winding supplied electrical drive power, and accordingly, the piston stroke is variable.
  • the amplitude of the armature can become so great that the piston strikes a boundary of the compression chamber. This leads to a strong noise and possibly also to a damage of the compressor. In addition, the vibration of the armature and the driving alternating current get out of phase, so that for this reason the drive loses effectiveness.
  • Tolerances in the manufacture of the linear compressors can cause the path that the armature can travel from its equilibrium position until the piston encounters a limit can vary from one linear compressor to another. If, taking into account the manufacturing tolerances of the armature stroke for all linear compressor is uniformly determined so that the piston can not hit the limit, resulting from one compressor to another significantly different dead volumes and thus different efficiencies.
  • the equilibrium position in which the armature is with the compressor off, depending on the pressure prevailing in the compression chamber, acting on the piston pressure may be different. Different pressures can easily occur when using the linear compressor for compressing refrigerant in a refrigerator, depending on how the average temperature or the ratio of gaseous to liquid refrigerant in the refrigerant circuit of the device. If a refrigeration unit is put into operation new or after a long standstill and the refrigerant circuit has to be cooled down from room temperature, the pressure in the refrigerant circuit is initially higher than in an operating unit in which the cold room and consequently also at least part of the refrigerant clearly colder than room temperature.
  • a vibration amplitude, which results in a usable device, a useful, small dead volume may be insufficient in the case of restart, since here the rest position, by which the armature oscillates, is shifted. If this results in a large dead volume, the efficiency of the compressor can be so far affected in extreme cases that a proper cooling down of the device is not possible.
  • the object of the present invention is to provide a method for operating a linear compressor which avoids the problems described above.
  • a linear compressor comprising a linear drive with a winding and a displaceable by the magnetic field of the coil against a spring force armature and a compressor chamber in which a piston is coupled to the armature movable, wherein in operation, the winding is applied with an alternating current to drive a swinging motion of the armature, this winding is acted upon before operation with a direct current with a first sign to move the armature from a rest position by a first end position, the armature under the action of the Direct current is measured, measured, and during operation, the magnitude of the alternating current, with which the winding is energized, is controlled so that the armature does not reach the first end position or with vanishing speed.
  • the first sign of the DC current is set so that is moved by the resulting from the action of the DC current displacement of the piston, the piston on a valve plate of the compression chamber, since in this direction, the freedom of movement of the piston is necessarily limited and accurate control of the piston stroke is required to ensure a small dead volume and thus a good efficiency.
  • the winding is further supplied with a direct current opposite to the sign of the first sign before commencement of operation, that a second end position which the armature reaches under the effect of this direct current is measured, and that during operation
  • the strength of the alternating current that energizes the winding is controlled so that the armature does not reach the second end position either at or with vanishing speed.
  • the strength of the DC current is expediently increased gradually to avoid that the piston abuts a boundary at high speed.
  • the position of the armature is repeatedly measured, and as the end position, a position of the armature is determined over which the armature does not move with a further increase of the current strength.
  • the deflection counteracts namely only the spring force and possibly the pressure in the compression chamber, it can be assumed that an increase in the current of the direct current also leads to an increase in the deflection, unless the piston has reached the limit.
  • a position of the armature can be determined as the end position in which it triggers a proximity sensor.
  • a proximity sensor may for example be a light barrier,
  • Fig. 1 schematically shows a linear compressor with a linear drive 1 and a compressor unit 2, which are held in a U-shaped frame 3 shown here.
  • An armature 6 is suspended in an air gap between the iron cores 4 by means of diaphragm springs 7, which keep the armature 6 slightly movable in the longitudinal direction of the air gap and rigid in the transverse direction.
  • the armature 6 includes two antiparallel poled permanent magnets 8, 9, which endeavor to align themselves in a magnetic field generated by the windings 5 and the armature 6 thus depending on the direction of current flow through the windings 5 the armature in the perspective of the left or right float.
  • the compressor unit 2 comprises a compression chamber 10, which is bounded on one side by a movable piston 11.
  • the piston 11 is rigidly connected to the armature 6 via a piston rod 12.
  • a support plate 13 On the armature 6, a support plate 13 is mounted, which is alternately provided with reflective or light-absorbing strip.
  • a first light barrier with a light source 14 which emits a focused light beam onto the carrier plate 13 and a light sensor 15 aligned with the carrier plate 13 is mounted on one of the iron cores 4. Depending on whether the light beam of the light source 14 strikes a reflective or an absorbing strip of the carrier plate 13, the light sensor 15 receives more or less light.
  • a comb-like structure may also be mounted on the armature 6, and light source 14 and light sensor 15 of the light barrier are mounted on the iron cores 4 on both sides of the comb structure, so that depending on the position of the armature 6, a tine of the comb structure the light sensor 15th shaded or the light beam from the light source 14 through a gap between two prongs reaches the light sensor 15.
  • a comb structure may also be provided a transparent support which is provided with spaced light-impermeable strips.
  • a second light barrier is arranged offset by a quarter period of the regular strip arrangement.
  • a control circuit 16 is connected, which supplies the windings 5 with electricity.
  • the control circuit 16 receives from the outside, for example from a thermostat control of a refrigerator, in which the linear compressor of Fig. 1 is installed, a commissioning command.
  • the control circuit 16 then acts on the windings 5 with a direct current whose current intensity I, as indicated by a dashed line in the diagram of Fig. 2 shown, increases linearly with time t. Proportional to the current I increases the force acting on the armature 6 magnetic force, the armature 6 in the perspective of the Fig. 1 drives to the right.
  • the principle of the invention is also applicable if this is not exactly the case:
  • the control circuit 16 With increasing displacement of the armature 6 a strip of the carrier plate 13 after the other passes the photocells.
  • the control circuit 16 detects the direction in which the armature 6 moves and increments (decrements, depending on the detected direction of movement) each time a stripe passes the first photoelectric switch 14,15 ) the control circuit 16 has a counter whose count n is thus representative of the distance traveled by the armature 6 from its rest position.
  • the count value n thus forms a likewise in the diagram of Fig. 2 illustrated step function of the time t.
  • the freedom of movement of the armature 6, measured in steps of the said counter, a fixed predetermined and stored in the control circuit 16 integer N.
  • the control circuit corresponding to the contact of the piston 11 with the valve plate 17 count value with the number N
  • a calibration of the position measurement is achieved: the limits of the permissible range of motion of the armature 6 correspond to a count of 0 and N.
  • the control circuit reduces the current I in the windings 5 from the time t 1 , to a reversal of their sign, while counted in the opposite direction, the strips which pass through the light barrier, from zero upwards. This happens until again increasing the amount of current no longer leads to a further increase in the meter reading.
  • the counter reading N thus obtained thus represents a measured value of the actual freedom of movement of the armature 6; he will be in the used the same way, as stated above for the fixed preset count N and explained in more detail below.
  • the diagrams of Fig. 3 illustrate the recording of the oscillating operation of the linear compressor.
  • the middle diagram schematically shows the time evolution of the position of the armature 6 and its target reversal points, the upper and the lower diagram respectively corresponding to the time evolution of the charge quantities Q + , Q - of positive and negative half-waves of one of the control circuit 16 to the windings 5 output excitation current.
  • the control circuit In order now to bring the oscillating movement of the armature 6 in motion, the control circuit first sets the armature position, which corresponds to the count N / 2, as the center of the oscillatory motion. The initial resting position of the armature then corresponds to a count denoted n 0 , which will generally be different from N / 2. At time t 2 in Fig. 3 The control circuit starts to excite the swinging motion.
  • the control circuit 16 initially acts on the windings only with positive half waves to raise the armature.
  • the time evolution of the charge amount Q + of the upper half-waves is shown in the upper diagram of FIG Fig. 3 shown; it starts with an initial value Q + (t 2 ) at time t 2 , which is proportional to the deviation between the armature rest position n 0 and the desired midpoint N / 2 of its swinging motion, and takes as the setpoint position u + of the upper reversal point with time t too.
  • the target position of the lower reversal point u - crosses the rest position n 0 .
  • the control circuit 16 starts to output negative half-waves.
  • the time evolution of their charge quantity Q - is in the lower diagram of Fig. 3 shown.
  • the control circuit 16 reduces the charge amount of the positive half-waves, if it detects a movement of the armature beyond the upper target turning point N- ⁇ and accordingly increases the amount of charge of the lower half-waves, such a displacement of the movement is avoided, so that the compressor unit. 2 works at any time with minimal dead volume, without it comes to striking the piston 11 in the compression chamber 10.
