- Embodiment 1 Prior to describing an embodiment of the present invention, a compressor and an inverter which is a driving device for driving the compressor will be described. Compressors mounted on air conditioners and other refrigeration and air conditioning systems that use permanent magnet motors have become widespread. Since the permanent magnet motor is a synchronous motor, it is necessary to control the conduction phase during the inversion according to the position of the rotor that constitutes the motor. Since a synchronous motor, which is a permanent magnet motor, is used, it has high energy savings such as no slip loss.
- the compressor places the motor inside the sealed container of high temperature and pressure. Therefore, in the case of a compressor, it is difficult to arrange a position detector for detecting the rotor position of the motor. Therefore, position sensorless drive is the mainstream of compressor drive.
- Fig. 1 is a diagram for explaining the driving method of the permanent magnet motor.
- Fig. 1 (a) shows the case of rectangular wave drive
- Fig. 1 (b) shows the case of sine wave drive.
- Fig. 1 (a) shows the case of rectangular wave drive
- Fig. 1 (b) shows the case of sine wave drive.
- Fig. 1 (a) shows the case of rectangular wave drive
- Fig. 1 (b) shows the case of sine wave drive.
- Fig. 1 (a) shows the case of rectangular wave drive
- Fig. 1 (b) shows the case of sine wave drive.
- a pause section in which energization is suspended, and during this pause section, the back electromotive voltage that can be detected from the motor terminal is detected, and the rotor position is detected.
- square wave drive it is possible to directly detect the back electromotive voltage of the motor during the power interruption period. Therefore, it is possible to drive even a permanent magnet motor having a different specification.
- the position sensorless drive using sine wave drive uses a motor constant that indicates the specifications of a permanent magnet motor connected to the inverter and calculates the rotor position or energizing phase from this motor constant to calculate the position sensorless. Is the way.
- V / f the gradient of the applied voltage with respect to the number of rotations of the motor
- An increase in the V / f of the motor means that the current flowing through the motor can be reduced, so a motor with a large V / f can generally be said to be a motor with better efficiency.
- invertors for sine-wave driven compressors have begun to be commercialized in recent years, but since sine-wave drive uses motor constants, motor constants can be reduced by integrating the inverter and motor. If the motor must be handled in a known state and a motor with a different motor constant is connected to the data stored inside, the motor cannot be driven.
- the compressor could be driven simply by replacing the compressor, but in the case of sine wave drive, the motor constant was required, so simply It is impossible to drive simply by replacing the compressor, and it is necessary to replace the drive, which is a drive unit. Therefore, regardless of the specification of the permanent magnet motor, the constants of the motors are identified by the driver itself, and an automatic tuning function is added to the driver so that the motor can be driven using the identified motor constants. By doing so, it becomes possible for any compressor equipped with a motor of any specification (for example, a compressor driven by a sine wave) to be driven after the compressor is replaced.
- the automatic tuning function refers to a function of identifying a motor constant of a motor to be driven.
- constant identification such as inertia (also called inertia) of the load connected to the motor and control coefficients such as the gain of the controller is included.
- the motor constants of the permanent magnet motor are the same as those of the commonly known four motor constants: phase resistance, d-axis inductance, q-axis inductance, and back electromotive force constant.
- the amount of voltage that can be started is automatically set all over the time, and the rotational speed limit for forcible rotation is also set.
- the method of identifying the phase resistance is the easiest way to identify the resistance component.To identify the resistance component, it is easiest to identify the resistance component from the constrained current that flows when a DC voltage is applied to the motor so that the motor is constrained. It is. This means that if the motor is bound, This can be considered as an LR load. When a DC voltage (for example, E) is applied to the LR load, the current converges to a constant value (E / R) and stabilizes after a certain period of time.
- E constant value
- the motor is a permanent magnet motor, and when the motor rotates, an induced pressure by a permanent magnet provided on the rotor is induced on the stator side of the motor. For this reason, the above-described resistance identification method has been described with respect to the method of identifying the resistance while restricting the motor from rotating. However, it is better to identify the inductance component without rotating the motor.
- a high-frequency pulse voltage is applied to the motor.
- a pulse current flows through the motor due to the applied pulse voltage, if the motor does not rotate due to the application of the pulse voltage, the motor can be considered as an LR load as described above.
- the applied pulse time is very small and much smaller than the time constant of LR, the effect of the resistance component R on the flowing pulse current does not appear.
- the resistance component R can be removed by applying the pulse, and the effect of the induced voltage can be neglected because the motor does not rotate. Therefore, the inductance component can be identified from the applied pulse voltage and the detected pulse current.
- the identification method of the back electromotive force constant is as follows. If the motor is rotating stably by forced rotation, the differential term that becomes the transient term in the motor's voltage-current equation during stable rotation is zero. Therefore, the back electromotive force constant may be calculated by back calculation from the voltage-current equation of the motor. However, in this case, since the phase resistance R of the motor and the inductance components Ld and Lq are used in the voltage-current equation, the identification can be performed by performing the above-described identification of the resistance and the inductance. It should be noted that there is no problem if the order of the identification of the resistance and the identification of the inductance is first.
- the automatic tuning function described here not only identifies constants so that it operates regardless of motor specifications, but also identifies constants so as not to impair the energy conservation of permanent magnet motors.
- the method for optimally driving the motor is performed.
- the phase current minimum control of the motor may be performed.
- the torque of the motor is expressed by an equation using the motor constant, and the minimum value of the phase current can be obtained by differentiating the current component of the equation representing the output torque.
- the motor efficiency does not reach the maximum due to the iron loss included in the motor, but it can be driven in a state very close to the maximum efficiency.
- the motor constant identification technology is a very important technology when driving a permanent magnet motor.
- the refrigeration / air-conditioning system has a refrigeration cycle in which the refrigerant discharged from the compressor is circulated through a condenser, an expansion valve, and an evaporator and returned to the compressor.
- an automatic tuning function is used for a service that provides users with low-cost energy-saving technologies, which are increasing year by year. In addition, this will prevent energy loss from homes and stores that increase without anyone noticing due to the deterioration of product performance, and it is an effective environmental measure and specification.
- the compressor In refrigeration and air conditioning equipment such as air conditioners, the compressor is the heart of It is no exaggeration to say that functional capacity determines the capacity of refrigeration and air conditioning equipment such as air conditioners.
- functional capacity determines the capacity of refrigeration and air conditioning equipment such as air conditioners.
- compressors In order to increase the efficiency of refrigeration and air conditioning equipment such as air conditioners, compressors are being improved year by year, and the shape of the applied permanent magnet motors and the materials used are being improved. Higher efficiency and quietness are realized.
- an air-conditioning air conditioner that is more inexpensive and energy-saving than replacing an air conditioner by using an automatic tuning function and replacing it with a compressor equipped with a more efficient motor Intended to be exchangeable

Then, in the service contract extension confirmation step S-6, Meiichi confirms with the user whether to extend the service contract.

- the air conditioner purchased by the user in step S-1 is an in-built air conditioner having an automatic tuning function. Since the air conditioner is installed, the air conditioner can be operated simply by replacing the compressor with any specifications.

Further, it is possible to prevent wasteful energy loss, which is a social loss.

This is paid, and if there is a new high-performance compressor developed during that period, the compressor will be replaced at any time.

- air conditioner manufacturers one that manufactures compressors in-house and one that purchases compressors from other companies without manufacturing them. Manufacturers that manufacture compressors in-house sell compressors to other manufacturers (hereinafter referred to as external manufacturers), and manufacturers that purchase (hereinafter referred to as purchase manufacturers) use the compressors provided by each external manufacturer. After evaluation, the compressor to be used is selected.
- External compressors equipped with a permanent magnet motor are usually provided as a sample with Inverahi.
- An embodiment of the present invention aims to provide a service that provides an automatic tuning invagator function to a manufacturer who purchases a compressor and manufactures a product. This makes it possible to perform absolute evaluation using the same circuit overnight circuit.
- FIG. 6 (a) the conventional comparative evaluation using the combination of the compressor provided in the set and Inver Night as shown above is shown.
- Fig. 6 (a) there is no problem if the invertor is purchased together with the compressor as a set, but there are manufacturers that sell only the compressor without selling the inverter and only the compressor later. Considering the case of purchasing, it is not possible to evaluate under the same conditions in the evaluation of Imbar overnight provided with another compressor and a set, which poses a problem. If only Invera is manufactured in-house, the in-house manufactured in-house must have the same performance as Invera provided with the compressor. Therefore, it may not be possible to output the desired performance from the compressor during the in-house production.
- the efficiency of a permanent magnet motor is calculated by two factors: copper loss (I 2 R) caused by current flowing through the motor and iron loss caused by the iron used in the motor. Can be separated into two. The balance between these two losses is important for motor efficiency, and the most efficient operating point of a motor is often not the point where the current is lowest (the minimum point of copper loss).
- the efficiency of the invertor is low even at the most efficient operating point of the motor, and the highest efficiency point of the power input, which is the total efficiency of the motor and the invertor, is the most efficient operating point of the motor. May not match. Therefore, it is meaningless to evaluate the efficiency only with the compressor, excluding the inverter, if the compressor does not operate without the inverter. However, this is a very important task in evaluating efficiency.
- the external compressor is operated in the same invar, and a state close to the form of the product starting from the power input point (the same ring)
- the comparison evaluation in (1) is realized by Invera with an automatic tuning function.
- the efficiency is evaluated at the inverter with the automatic tuning function, and the same efficiency evaluation results as those obtained when driving with the in-house inverter manufactured in-house are obtained.
- Invera is an auto-inverter that can evaluate its efficiency on the same playing field with a manufacturer that manufactures it in-house. The provision of evenings alone eliminates the need for the purchaser to prototype prototypes for evaluation, which can reduce development time and cost of prototype production.
- the manufacturer who purchases the compressor that requires the automatic tuning inverter is the service provider

- the automatic tuning inva overnight is provided (S-13), and the absolute evaluation (S-14) on the same ring by the same inva is performed.
- a compressor with the best efficiency and operating range can be purchased (S-15).
- the procedure described here may be any procedure, and the procedure is performed based on the evaluation criteria of the service user side. It goes without saying that FIG. 7 is an example.
- compressors have been manufactured in-house until now, but with the change of refrigerant, it is expected that some manufacturers will use compressors sold outside the company. Even for such manufacturers, by providing automatic tuning inverter service, it is possible to perform absolute evaluation of compressors that could not be driven due to differences in refrigerant on the same ring, And development costs can be reduced.
- the maximum capacity is the maximum output of the refrigeration cycle with the compressor installed. If this seems to decrease, the air conditioner may not be able to meet the product specifications such as a decrease in the heating capacity at low temperatures. descend. Also, if the minimum output increases, the air conditioner will be too cold in summer, etc., which will also lower the product specifications. Therefore, it is extremely important to evaluate the same condition before the final form. Even in this case, if the member with the automatic tuning function described in the present embodiment can be used, the ability and output can be evaluated on the same ring even before the final form.
- the present invention is not limited to the compressor, and is not limited to a compressor, and may be used for driving a permanent magnet motor without a position sensor, such as a pump motor. Needless to say, the service has the same effect
