[0026] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of protection of the present application.

[0027] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0028] To address the problem of poor vibration damping in existing technologies that rely on adding rubber rings or vibration dampers to compressors, this application provides a control method for an air conditioning compressor. The air conditioner in this embodiment includes a symmetrically arranged first compressor and second compressor. Based on this, as follows... Figure 1 As shown, the method steps in the embodiments of this application include:

[0029] Step 101: Position the rotors of the first compressor and the second compressor so that the rotors of the first compressor and the second compressor are symmetrically arranged.

[0030] In specific examples, such as Figure 2 As shown, 1 is the first compressor and 2 is the second compressor, and the first compressor and the second compressor are axially symmetrical along the line L. Therefore, the symmetrical arrangement of the rotors of the first compressor and the second compressor can mean that they are axially symmetrical about the line L, such as the first compressor position 3 and the second compressor position 9 being axially symmetrical, or the first compressor position 6 and the second compressor position 10 being axially symmetrical.

[0031] Step 102: Control the first compressor and the second compressor to run in opposite directions;

[0032] In this specific example, controlling the first compressor and the second compressor to operate in opposite directions can mean that the first compressor operates clockwise and the second compressor operates counterclockwise, or vice versa. Furthermore, the operating speeds of the first compressor and the second compressor are the same.

[0033] Step 103: Adjust the current of the first compressor or the second compressor, and control the operation of the first compressor and the second compressor based on the adjusted current, wherein the current difference between the first compressor and the second compressor after adjustment is less than a preset threshold.

[0034] In a specific example, the currents in the current running processes of the first compressor and the second compressor are different, and therefore, in the embodiments of the present application, the currents of the two compressors can be adjusted to be as consistent as possible, so that the running frequencies of the first compressor and the second compressor are close to each other.

[0035] Through the above steps 101 to 103, in the embodiments of the present application, the rotors of the first compressor and the second compressor are positioned to be symmetrically arranged, and the first compressor and the second compressor are controlled to run in opposite directions, that is, the rotors of the two compressors are in opposite phases and run in different rotation directions, so that the vibrations of the two compressors can be offset to a certain extent. At this time, the current difference between the first compressor and the second compressor is further adjusted to be less than a preset threshold, that is, the running frequencies of the two compressors are close to each other. On the basis of the rotors of the two compressors being in opposite phases and running in different rotation directions, the vibrations of the compressors can be further offset, so that the noise generated by the air conditioning unit during operation can be greatly reduced. In addition, in the embodiments of the present application, no additional device is added to offset the vibration of the compressor, so that the additional power consumption caused by adding a rubber ring at the foot pad or adding a vibration generator to offset the vibration of the compressor in the prior art can be avoided.

[0036] In the embodiments of the present application, the rotors can be positioned by the sensors arranged on the compressors, and then it is determined whether the rotors of the two compressors are symmetrically arranged. Therefore, the manner of positioning the rotors of the first compressor and the second compressor to be symmetrically arranged in step 101 can further include:

[0037] Step 11, selecting any first sensor from the plurality of sensors of the first compressor; wherein the plurality of sensors in the first compressor and the plurality of sensors of the second compressor form a plurality of symmetrically arranged groups of sensors;

[0038] Step 12, determining a second sensor of the same group as the first sensor from the plurality of groups of sensors, wherein the second sensor is a sensor in the second compressor;

[0039] Step 13, positioning the rotor of the first compressor at the first sensor, and positioning the rotor of the second compressor at the second sensor.

[0040] In this regard, in a specific example, the first sensor and the second sensor are selected from the plurality of sensors of the first compressor and the second compressor, respectively, and the rotors of the first compressor and the second compressor are positioned at the first sensor and the second sensor, respectively. Figure 3and the number of sensors on each compressor is 4, for example, the first compressor includes vibration sensor 3, vibration sensor 4, vibration sensor 5, and vibration sensor 6, and the second compressor includes vibration sensor 7, vibration sensor 8, vibration sensor 9, and vibration sensor 10, and the current Figure 3 According to the positional relationship in the current Figure 3 application, vibration sensor 3 and vibration sensor 9 are a set of symmetrically arranged sensors, vibration sensor 4 and vibration sensor 8 are a set of symmetrically arranged sensors, vibration sensor 5 and vibration sensor 7 are a set of symmetrically arranged sensors, and vibration sensor 6 and vibration sensor 10 are a set of symmetrically arranged sensors. For example, in the embodiment of the present application, the first sensor can be vibration sensor 3, and the corresponding second sensor is vibration sensor 9. The rotor is positioned by the sensors, which can make the positioning of the rotor convenient and fast, because only one of the sensors needs to be determined, and the other symmetric sensor can be determined. Of course, the above is only an example in which the number of sensors on one compressor is 4. In other application scenarios, the number of sensors can be set according to actual needs, for example, the number of sensors is 2 or 8, and so on.

[0041] In the embodiment of the present application, in addition to positioning the rotor by the sensors, the rotor can also be positioned by the rotation of the compressor so that the two can be symmetrically arranged. Therefore, the method of positioning the rotor of the first compressor and the rotor of the second compressor in step 101 so that the rotor of the first compressor and the rotor of the second compressor are symmetrically arranged can further include:

[0042] Step 21, positioning the rotor of the first compressor at a first target position and positioning the rotor of the second compressor at a second target position.

[0043] Step 22, controlling the rotation of the first compressor and the second compressor so that the first target position and the second target position are symmetric to each other.

[0044] It can be known from the steps 21 and 22 that the rotor of the first compressor is positioned at the first target position, and the rotor of the second compressor is positioned at the second target position in the embodiment. The first target position can be any position of the first compressor, and the second target position can also be any position of the second compressor. Although the first target position and the second target position are any positions, after positioning, it can be known that the first target position and the second target position are at specific positions of the compressor, so that the symmetry of the first target position and the second target position can be ensured when the compressor rotates. Therefore, after the rotors of the two compressors are positioned, the rotation of the first compressor and the second compressor can be controlled to make the first target position and the second target position symmetrical to each other, so that the rotors of the first compressor and the second compressor can also be symmetrically arranged. It can be seen that, compared with the positioning mode of the sensor, the above-mentioned mode can reduce the burden of the sensor on the compressor, and the symmetry of the rotors of the two compressors can also be realized.

[0045] In the embodiment, if the current difference between the first compressor and the second compressor is less than the first preset threshold, the current of the first compressor or the second compressor does not need to be adjusted. Only when the current difference between the first compressor and the second compressor exceeds the first preset threshold, the current of the first compressor or the second compressor needs to be adjusted. Therefore, the mode of adjusting the current of the first compressor or the second compressor in the step 103 can further include:

[0046] In the step 31, the current difference between the current of the first compressor and the current of the second compressor is obtained.

[0047] In the step 32, when the current difference exceeds the first preset threshold, the smaller value of the current of the first compressor and the current of the second compressor is compensated until the current difference between the current of the first compressor and the current of the second compressor is less than the first preset threshold.

[0048] When the currents of the first compressor and the second compressor are close, the operating frequencies of the first compressor and the second compressor are also close. In the case that the phases of the rotors of the first compressor and the second compressor are opposite and the rotation directions of the compressors are opposite, adjusting the currents of the two compressors to be close can further offset the vibration generated by the two compressors. Generally, the operating frequency of the compressor needs to be increased as the external temperature rises, so if the current difference between the two compressors exceeds the first preset threshold during the process of increasing the operating frequency, the current of the compressor with smaller current needs to be increased to ensure that the operating frequency of the compressor will not be reduced, and if the current of the compressor with larger current is reduced, the operating frequency of the compressor will be reduced, so the demand of the current environment cannot be met.

[0049] In the embodiments of the present application, when the current of the first compressor or the second compressor is adjusted, the product of the current difference of the two compressors multiplied by the target coefficient is compared with the second preset threshold, and the current of the first compressor or the second compressor is adjusted, and the product is close to 0 during the adjustment. Based on this, the way of adjusting the current of the first compressor or the second compressor involved in the above step 103 can further include:

[0050] Step 41, obtaining the current difference between the current of the first compressor and the current of the second compressor;

[0051] Step 42, in the case that the product of the current difference and the target coefficient exceeds the second preset threshold, compensating the smaller one of the current of the first compressor and the current of the second compressor until the product is less than the second preset threshold.

[0052] In some cases of the specific example, the built-in chip of the air conditioner may not be able to directly identify the current difference between the first compressor and the second compressor because the current difference is large. Therefore, by setting a target coefficient, the current difference can be reduced in proportion, thereby meeting the current identification range of the chip. However, the target coefficient cannot be too small, because the error of current adjustment will be large, thereby making the effect of current adjustment worse. Similarly, during the process of increasing the operating frequency, if the current difference between the two compressors exceeds the second preset threshold, the current of the compressor with smaller current needs to be increased to ensure that the operating frequency of the compressor will not be reduced, and if the current of the compressor with larger current is reduced, the operating frequency of the compressor will be reduced, and the current environmental demand cannot be met.

[0053] The present application will be explained and described in combination with the specific implementation manner of the embodiments of the present application, and the specific implementation manner provides a double-compressor system damping control method for an air conditioner, Figure 4 is a system structure schematic diagram of the specific implementation manner, and based on this, as Figure 5 shown, the method steps of the specific implementation manner include:

[0054] Step 501, the controller positions the two compressor rotors;

[0055] As Figure 3 shown, the damping device of the air conditioner in the specific implementation manner includes a rotor position detection device, the rotor position detection device includes vibration sensors 3, 4, 5, and 6 located around the compressor 1, and vibration sensors 7, 8, 9, and 10 located around the compressor 2; a current detection and feedback device, which further includes a current detector and a current comparator; and a controller for driving the compressor.

[0056] Two compressors are installed in the two corners of the unit symmetrically. Firstly, when the unit is ready to start the compressor, the controller first positions the rotors of the compressor 1 and the compressor 2, and detects the position of the compressor rotor in real time through the vibration sensors located around the compressor, positions the rotor of the compressor 1 at the vibration sensor 3, and positions the rotor of the compressor 2 at the vibration sensor 9. Or positions the rotor of the compressor 1 at the vibration sensor 4, and positions the rotor of the compressor 2 at the vibration sensor 8, etc.

[0057] Step 502, the controller controls the compressor;

[0058] Step 503, the current detector detects the currents I1 and I2 of the two compressors;

[0059] Step 504, the current comparator compares the currents of the two compressors and outputs Err = a (I1-I2);

[0060] Step 505, the controller compensates for the compressor with smaller current;

[0061] Step 506, whether Err tends to 0; if yes, execute step 507; if no, execute step 505;

[0062] It can be seen that after the rotor is positioned, the controller increases the frequency of the two compressors according to the current external temperature demand of the unit, detects the current of each phase of the two compressors through the current detector of the current detection and feedback device, and inputs the detected current value I1 of the compressor 1 and the current value I2 of the compressor 2 into the current comparator, compares the currents of the two compressors by the current comparator, and outputs the error Err = a (I1-I2). Wherein, a is a constant, which is used to improve the accuracy of the error Err, which is obtained by actual test. The error Err value is fed back to the controller, and the controller compensates for the compressor with smaller current to make the error Err tend to 0. At this time, the running frequencies of the two compressors are the same, the currents are the same, the directions are opposite, and the vibrations of the compressors are offset to reduce the noise generated during the operation of the unit.

[0063] Step 507, control the compressor to run normally.

[0064] From the above steps 501 to 507, it can be seen that the vibration sensors are arranged on the two compressors to detect the position of the rotor, and the rotors of the two compressors are positioned at opposite positions. The two compressors are controlled to run in different rotating directions, and the vibrations of the two compressors can be offset by controlling the same current of the compressor, that is, without increasing additional vibration devices to offset the vibration of the compressor as in the prior art.

[0069] By the device of the embodiment of the present application, the rotor of the first compressor and the rotor of the second compressor are positioned, so that the rotor of the first compressor and the rotor of the second compressor are symmetrically arranged, and then the first compressor and the second compressor are controlled to run in opposite directions, that is, the rotors of the two compressors are opposite in phase and run in different rotating directions, so that the vibrations of the two compressors can be offset to a certain extent. At this time, the difference between the currents of the first compressor and the second compressor is further adjusted to be less than the preset threshold, that is, the running frequencies of the two compressors are also close. On the basis of the rotors of the two compressors being opposite in phase and running in different rotating directions, the vibrations of the compressors can be further offset, so that the noise generated when the air conditioner unit runs can be greatly reduced.
