Description

Technical Field

[0001] This application belongs to the field of storage equipment, and particularly relates to a compressor control method, device and storage equipment for storage equipment. Background Technology

[0002] As people's living standards improve, their demands for home appliances are also increasing, and inverter refrigerators have become the first choice for ordinary people. In related technologies, the compressor control of inverter refrigerators is achieved through an inverter board. In actual use with mains power, the mains voltage changes in real time. When the voltage is low, the compressor still maintains high speed and high load, which is like a small engine pulling a heavy load. This can easily lead to a large current in the switching transistor, increasing the load on the control board, and even causing the drive components to overheat and damage the control board, affecting the lifespan of the refrigerator and thus impacting the user experience. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a compressor control method, apparatus, and storage device for storage equipment, which can effectively ensure the normal and stable operation of the storage equipment, significantly extend its service life, and thus improve the user experience.

[0004] In a first aspect, this application provides a compressor control method for a storage device, the method comprising:

[0005] Correct the input AC voltage to obtain the first bus voltage;

[0006] When the voltage of the first bus is less than the target threshold, the limited rotational speed is calculated based on the voltage of the first bus.

[0007] The actual speed of the compressor is controlled based on the defined speed and the set speed.

[0008] According to the compressor control method of the storage device of this application, when the first bus voltage is less than the target threshold, the actual speed of the compressor is controlled based on the limited speed calculated from the first bus voltage and the original set speed of the compressor, so as to control the compressor speed within a reasonable range, avoid excessive speed when the bus voltage is low, and thus control the switching tube current to keep it within a suitable range. This can effectively ensure the normal and stable operation of the storage device, significantly extend the service life of the storage device, and improve the user experience.

[0009] According to one embodiment of this application, the step of calculating the limited rotational speed based on the first bus voltage includes:

[0010] The limited speed is calculated based on the first bus voltage, the maximum speed of the compressor, and the target threshold.

[0011] According to one embodiment of this application, calculating the limited speed based on the first bus voltage, the maximum speed corresponding to the compressor, and the target threshold includes:

[0012] The specified rotational speed is calculated using the following formula:

[0013] n1=U1×n max / U0

[0014] Wherein, n1 is the limited rotational speed; U1 is the first bus voltage; n max U0 is the maximum rotational speed; U0 is the target threshold.

[0015] According to the compressor control method of the storage device of this application, by constructing the relationship between the first bus voltage, the maximum speed, the target threshold and the limited speed, the limited speed can be made to change proportionally to the change of the first bus voltage. It can also effectively combine the power output and other factors to avoid excessive speed when the bus voltage is low, while keeping the compressor running at a relatively high speed within a reasonable speed range, without affecting the normal performance of the storage device, and effectively ensuring the normal and stable operation of the storage device. Moreover, it is simple and convenient to operate, with fast control efficiency and high control accuracy.

[0016] According to one embodiment of this application, controlling the actual speed of the compressor based on the defined speed and the set speed includes:

[0017] When the set speed is less than the limited speed, the actual speed of the compressor is controlled based on the set speed;

[0018] When the set speed is not less than the limited speed, the actual speed of the compressor is controlled based on the limited speed.

[0019] According to one embodiment of this application, the step of correcting the input AC voltage to obtain the first bus voltage includes:

[0020] The sum of the DC voltage corresponding to the AC voltage and the correction value is determined as the first bus voltage.

[0021] According to one embodiment of this application, before correcting the input AC voltage, the method further includes:

[0022] With the compressor running, the AC voltage is collected based on a target duration.

[0023] Secondly, this application provides a compressor control device for a storage device, the device comprising:

[0024] The first processing module is used to correct the input AC voltage to obtain the first bus voltage;

[0025] The second processing module is used to calculate the limited rotational speed based on the first bus voltage when the first bus voltage is less than the target threshold.

[0026] The third processing module is used to control the actual speed of the compressor based on the limited speed and the set speed.

[0027] According to the compressor control device of the storage equipment of this application, when the first bus voltage is less than the target threshold, the actual speed of the compressor is controlled based on the limited speed calculated from the first bus voltage and the original set speed of the compressor, so as to control the compressor speed within a reasonable range, avoid excessive speed when the bus voltage is low, and thus control the switching tube current to keep it within a suitable range. This can effectively ensure the normal and stable operation of the storage equipment, significantly extend the service life of the storage equipment, and improve the user experience.

[0028] Thirdly, this application provides a storage device, comprising:

[0029] Cabinet;

[0030] The compressor is located within the cabinet.

[0031] The compressor control device for the storage equipment as described in the second aspect is electrically connected to the compressor.

[0032] According to the storage device of this application, when the first bus voltage is less than the target threshold, the actual speed of the compressor is controlled based on the limited speed calculated from the first bus voltage and the original set speed of the compressor, so as to control the compressor speed within a reasonable range and avoid excessive speed when the bus voltage is low. This controls the switching tube current to remain within a suitable range, effectively ensuring the normal and stable operation of the storage device, significantly extending the service life of the storage device, and thus improving the user experience.

[0033] Fourthly, this application provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the compressor control method for the storage device as described in the first aspect above.

[0034] Fifthly, this application provides a computer program product, including a computer program that, when executed by a processor, implements the compressor control method for the storage device as described in the first aspect above.

[0035] The above-described one or more technical solutions in the embodiments of this application have at least one of the following technical effects:

[0036] By controlling the actual speed of the compressor based on the limited speed calculated from the first bus voltage and the original set speed of the compressor when the first bus voltage is less than the target threshold, the compressor speed is kept within a reasonable range. This avoids excessive speed when the bus voltage is low, thereby controlling the switching current to remain within a suitable range. This effectively ensures the normal and stable operation of the storage equipment, significantly extends the service life of the storage equipment, and improves the user experience.

[0037] Furthermore, by correcting the rectified DC voltage, the error caused by heavy loads can be reduced, thereby improving the accuracy and precision of subsequent detection and control results, enhancing compressor speed control, and improving the user experience. This makes it suitable for various application scenarios.

[0038] Furthermore, by constructing a relationship between the first bus voltage, maximum speed, target threshold, and limited speed, the limited speed can be made to change proportionally to the change in the first bus voltage. It can also effectively combine factors such as power output to avoid excessive speed when the bus voltage is low, while keeping the compressor running at a relatively high speed within a reasonable speed range. This does not affect the normal performance of the storage equipment and effectively ensures the normal and stable operation of the storage equipment. Moreover, it is simple and convenient to operate, with fast control efficiency and high control accuracy.

[0039] Furthermore, by sampling the AC voltage at regular intervals to adjust the compressor speed, the energy consumption of the storage equipment can be reduced while ensuring its normal and stable operation, thereby further improving the user experience.

[0040] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0048] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0049] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0050] The following description, in conjunction with the accompanying drawings, details the compressor control method for storage devices, the compressor control device for storage devices, the storage devices, and the readable storage medium provided in this application, through specific embodiments and application scenarios.

[0051] The compressor control method for storage equipment can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0052] The compressor control method for storage devices provided in this application embodiment can be executed by the storage device itself or by a functional module or entity within the storage device that can implement the compressor control method. The storage device mentioned in this application embodiment can be understood as a broad category of refrigeration and storage devices, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. Storage devices have diverse structural forms and wide applications. The compressor control method for storage devices provided in this application embodiment will be described below using a storage device as the executing entity.

[0053] It should be noted that, when the storage device is a refrigerator, the compressor control method of the storage device can also be applied to inverter refrigerators, where the compressor control of the inverter refrigerator is achieved through an inverter board.

[0054] like Figure 1 As shown, the compressor control method of the storage device includes steps 110, 120 and 130.

[0055] Step 110: Correct the input AC voltage to obtain the first bus voltage;

[0056] In this step, the AC voltage can be the voltage of the mains power supply to which the storage device is connected.

[0057] It is understandable that the voltage of mains electricity is a variable voltage.

[0058] In some cases, the voltage of the mains power may be lower, such as dropping from 220 volts to around 100 volts.

[0059] The first bus voltage is the theoretical bus voltage obtained after further correcting the DC voltage after converting AC to DC through rectification.

[0060] like Figure 2 As shown, in some embodiments, step 110 may include:

[0061] The sum of the DC voltage corresponding to the AC voltage and the correction value is determined as the first bus voltage.

[0062] In this embodiment, the DC voltage corresponding to the AC voltage is the voltage obtained by rectifying the collected AC voltage.

[0063] The correction value can be determined based on historical data or it can be based on user-defined values; this application does not impose any restrictions on this.

[0064] In some embodiments, the correction value can be set to 20V or 21V, etc., and this application does not limit it.

[0065] It should be noted that in actual operation, when the input AC value is 187V, the theoretical bus DC voltage is 1.414 * 187 = 264V. However, in reality, when the load is relatively heavy, the bus voltage often does not reach the theoretical bus DC voltage of 264V when the input is 187V, but is only about 244V. In this case, by correcting the DC voltage converted from the actual AC voltage to obtain the corresponding theoretical bus voltage, the error can be reduced and the accuracy and precision of subsequent control can be improved.

[0066] For example, with an AC voltage of 150V, a DC voltage of approximately 192V can be obtained by rectifying it. Then, by correcting the DC voltage, taking a correction value of 20V as an example, the first bus voltage of 212V can be obtained.

[0067] In some embodiments, it can be based on Figure 3 The rectifier circuit shown performs rectification.

[0068] Continue to refer Figure 3 CN1 includes a first pin and a second pin connected to the L line and N line respectively, and a third pin grounded.

[0069] BD1 is used for rectification. The current obtained after rectification by BD1 is filtered by capacitors and inductors connected in series and parallel to obtain DC voltage.

[0070] In this embodiment, filtering can further reduce errors and improve the precision and accuracy of control.

[0071] According to the compressor control method for storage devices provided in the embodiments of this application, by correcting the rectified DC voltage, the error caused by heavy load can be reduced, further improving the accuracy and precision of subsequent detection and control results, improving the compressor speed control effect, thereby improving the user experience, and is applicable to a variety of application scenarios.

[0072] Step 120: When the first bus voltage is less than the target threshold, calculate the limited rotational speed based on the first bus voltage;

[0073] In this step, the target threshold is the minimum critical value of the bus voltage used for speed limiting. That is, if it is lower than the target threshold, it can be considered that the voltage is too low and may conflict with the high-speed rotating compressor, affecting the normal operation of the storage equipment. In this case, the speed limiting mode needs to be triggered.

[0074] The target threshold can be determined based on experiments or can be user-defined.

[0075] After multiple tests by the inventor, it was confirmed that when the input AC voltage is above 187 volts and the compressor load is normal, the maximum speed of 4500 rpm can be achieved. However, when the input AC voltage is below 187 volts, even if the voltage is saturated, the maximum speed cannot be met. Based on this, the target threshold can be determined based on the AC voltage of 187V, such as setting it to 264V.

[0076] Of course, the target threshold is not a uniquely determined value; it can be flexibly set based on different application scenarios and environments, and this application does not impose any restrictions.

[0077] The speed limit is the maximum threshold of the compressor speed when the speed limit mode is enabled.

[0078] The speed limit is proportional to the voltage of the first bus.

[0079] For example, the speed limit can be set to vary linearly with the voltage of the first bus; the smaller the voltage of the first bus, the smaller the corresponding speed limit.

[0080] In actual execution, the speed limit can be determined in any feasible way.

[0081] For example, a correlation table between the first bus voltage and the specified speed can be pre-established, and the specified speed corresponding to each first bus voltage can be obtained by looking up the table.

[0082] For example, the first bus voltage can be input into a pre-trained neural network model to obtain the limited rotational speed corresponding to the first bus voltage output by the neural network model.

[0083] In some embodiments, calculating the limited rotational speed based on the first bus voltage in step 120 may include:

[0084] The limited speed is calculated based on the first bus voltage, the maximum speed of the compressor, and the target threshold.

[0085] In this embodiment, the maximum speed corresponding to the compressor is the maximum speed that the compressor can reach under normal compressor load conditions.

[0086] The maximum speed can be determined based on factors such as the type of compressor and the amount of mains power.

[0087] For example, in some embodiments, for storage devices developed based on 220V AC mains power, the DC voltage of the bus after rectification and filtering can reach 310V; on this basis, the compressor frequency conversion speed regulation can be adjusted between 1000 rpm and 4500 rpm, that is, under normal compressor load, the maximum speed can be 4500 rpm.

[0088] Of course, for specific regions and other countries, the target threshold and maximum speed can be flexibly set based on the actual situation, and this application does not impose any restrictions.

[0089] In actual execution, a quantitative relationship can be established between the first bus voltage, maximum speed, target threshold, and limited speed. Based on the first bus voltage, the maximum speed of the compressor, and the target threshold, the limited speed can be calculated.

[0090] This relationship can be constructed based on a large amount of experimental data, so that when the relationship is satisfied, the compressor can rotate at a speed not exceeding the limit speed, and the switching tube current can be controlled to remain within a suitable range without being too large without affecting the normal performance.

[0091] In some embodiments, calculating the limited speed based on the first bus voltage, the maximum speed of the compressor, and the target threshold may include:

[0092] The specified rotational speed is calculated using the following formula:

[0093] n1=U1×n max / U0

[0094] Where n1 is the limited rotational speed; U1 is the first bus voltage; n max U is the maximum rotational speed; U0 is the target threshold.

[0095] In this embodiment, taking an AC voltage of 150V as an example, by rectifying and correcting the 150V AC voltage, the first bus voltage of 212V can be obtained. Then, by substituting into the above formula: 212×4500 / 264=3613, the limited speed of 3613 revolutions can be obtained.

[0096] Understandably, by setting the formula, the accurate speed limit can be calculated for any first bus voltage, which has high precision, accuracy and calculation efficiency.

[0097] Of course, in other embodiments, the above relationship can be updated or modified based on the actual situation to achieve the best control effect for the calculated limited rotational speed.

[0098] According to the compressor control method for storage equipment provided in the embodiments of this application, by constructing a relationship between the first bus voltage, the maximum speed, the target threshold, and the limited speed, the limited speed can be made to change proportionally to the change of the first bus voltage. It can also effectively combine factors such as power output to avoid excessive speed when the bus voltage is low, while keeping the compressor running at a relatively high speed within a reasonable speed range, without affecting the normal performance of the storage equipment, and effectively ensuring the normal and stable operation of the storage equipment. Moreover, it is simple and convenient to operate, with fast control efficiency and high control accuracy.

[0099] Step 130: Based on the limited speed and the set speed, control the actual speed of the compressor.

[0100] In this step, the speed is set to the preset speed of the compressor under the current operating conditions.

[0101] It is understandable that the set speed may be higher than the limit speed, lower than the limit speed, or equal to the limit speed.

[0102] The compressor can be set to run at a set speed without the speed limit being enabled.

[0103] When the speed limit is enabled, the compressor can be controlled to run at the set speed or the limited speed, depending on the relationship between the limited speed and the set speed.

[0104] The implementation method of step 130 will be explained in detail below.

[0105] Continue to refer Figure 2 In some embodiments, step 130 may include:

[0106] When the set speed is lower than the limit speed, the actual speed of the compressor is controlled based on the set speed.

[0107] When the set speed is not less than the limit speed, the actual speed of the compressor is controlled based on the limit speed.

[0108] In this embodiment, if the set speed is less than the limit speed, it can be approximately assumed that the current actual speed of the compressor is less than the limit speed, that is, the current speed is a reasonable speed, and then the compressor is controlled to keep rotating at the set speed.

[0109] If the set speed is not less than the limit speed, it can be approximately assumed that the current actual speed of the compressor is not less than the limit speed. That is, if the current speed is too high, it is easy to cause the switching tube current to be large if the compressor continues to run at a high speed, which will increase the load on the control board. In this case, the current speed of the compressor should be reduced. At the same time as reducing the speed, the normal operation of the compressor should not be affected. Therefore, the compressor can be controlled to run at the limit speed.

[0110] In actual implementation, it can be achieved through methods such as... Figure 6 The algorithm program shown executes the above steps.

[0111] In this application, the input voltage is determined by setting a target threshold. When the first bus voltage is less than the target threshold, the speed limit is activated to prevent the compressor speed from being too high. The switching current is controlled to remain within a suitable range. This reduces the risk of increased switching current, increased load on the control board, and damage to the control board due to overheating of the drive components caused by the compressor maintaining a high speed when the bus voltage is low. This extends the service life of the storage equipment, effectively ensures the normal and stable operation of the storage equipment, and thus improves the user experience.

[0112] According to the compressor control method of the storage device provided in the embodiments of this application, the actual speed of the compressor is controlled based on the limited speed calculated from the first bus voltage and the original set speed of the compressor when the first bus voltage is less than the target threshold. This keeps the compressor speed within a reasonable range and avoids excessive speed when the bus voltage is low. In this way, the switching current is kept within a suitable range, which can effectively ensure the normal and stable operation of the storage device, significantly extend the service life of the storage device, and improve the user experience.

[0113] Continue to refer Figure 2 In some embodiments, before step 110, correcting the input AC voltage, the method may further include:

[0114] With the compressor running, AC voltage is collected based on the target duration.

[0115] In this embodiment, the target duration is the time interval during the AC voltage acquisition process.

[0116] The target duration is a relatively long duration, which can be user-defined, such as 1ms, 1.5ms or other values, and this application does not impose any restrictions.

[0117] In actual operation, the compressor speed can be adjusted once for each AC voltage collected.

[0118] According to the compressor control method for storage devices provided in this application, the compressor speed is adjusted by collecting AC voltage at regular intervals. This eliminates the need for high-frequency voltage collection, ensuring the normal and stable operation of the storage device while reducing its energy consumption and further improving the user experience.

[0119] The following example uses a correction value of 20V, a maximum speed of 4500 rpm, and a target threshold of 264V as an example to illustrate the specific implementation of this embodiment.

[0120] Continue to refer Figure 2 First, determine whether the compressor is running. If the compressor is running, collect the AC voltage every target duration (e.g., every 1ms). After rectifying the collected AC voltage, correct it based on the correction value to obtain the first bus voltage. Then, determine whether the first bus voltage is less than 264V.

[0121] If the voltage of the first bus is not less than 264V, control the compressor to maintain the current speed and enter the next round of AC voltage acquisition.

[0122] When the first bus voltage is less than 264V, the limited speed corresponding to the first bus voltage is calculated using the formula: first bus voltage × 4500 / 264, and the relationship between the limited speed and the set speed is determined.

[0123] If the set speed is lower than the limit speed, the compressor is controlled to maintain the set speed and then proceed to the next round of AC voltage acquisition.

[0124] When the set speed is not less than the limit speed, the compressor is controlled to run at the limit speed and then enters the next round of AC voltage acquisition, and so on.

[0125] Through numerous experiments, the inventors have determined that the method based on this application can better meet the product usage requirements, maximize the operating speed, ensure the normal operation of the control board, effectively reduce safety hazards, and improve the performance of the storage equipment and the user experience.

[0126] The compressor control method for storage devices provided in this application can be executed by a compressor control device for the storage device. This application uses the compressor control device of the storage device executing the compressor control method as an example to illustrate the compressor control device for the storage device provided in this application.

[0127] This application also provides a compressor control device for a storage device.

[0128] like Figure 4 As shown, the compressor control device of the storage equipment includes: a first processing module 410, a second processing module 420 and a third processing module 430.

[0129] The first processing module 410 is used to correct the input AC voltage to obtain the first bus voltage;

[0130] The second processing module 420 is used to calculate the limited rotational speed based on the first bus voltage when the first bus voltage is less than the target threshold.

[0131] The third processing module 430 is used to control the actual speed of the compressor based on the limited speed and the set speed.

[0132] According to the compressor control device of the storage device provided in the embodiments of this application, when the first bus voltage is less than the target threshold, the actual speed of the compressor is controlled based on the limited speed calculated from the first bus voltage and the original set speed of the compressor. This keeps the compressor speed within a reasonable range, avoids excessive speed when the bus voltage is low, and controls the switching current to remain within a suitable range. This effectively ensures the normal and stable operation of the storage device, significantly extends the service life of the storage device, and improves the user experience.

[0133] In some embodiments, the second processing module 420 may also be used for:

[0134] The limited speed is calculated based on the first bus voltage, the maximum speed of the compressor, and the target threshold.

[0135] In some embodiments, the second processing module 420 may also be used for:

[0136] The specified rotational speed is calculated using the following formula:

[0137] n1=U1×n max / U0

[0138] Where n1 is the limited rotational speed; U1 is the first bus voltage; n max U is the maximum rotational speed; U0 is the target threshold.

[0139] According to the compressor control device for storage equipment provided in the embodiments of this application, by constructing a relationship between the first bus voltage, the maximum speed, the target threshold, and the limited speed, the limited speed can be made to change proportionally to the change of the first bus voltage. It can also effectively combine factors such as power output to avoid excessive speed when the bus voltage is low, while keeping the compressor running at a relatively high speed within a reasonable speed range, without affecting the normal performance of the storage equipment, and effectively ensuring the normal and stable operation of the storage equipment. Moreover, it is simple and convenient to operate, with fast control efficiency and high control accuracy.

[0140] In some embodiments, the third processing module 430 can also be used for:

[0141] When the set speed is lower than the limit speed, the actual speed of the compressor is controlled based on the set speed.

[0142] When the set speed is not less than the limit speed, the actual speed of the compressor is controlled based on the limit speed.

[0143] In some embodiments, the first processing module 410 may also be used for:

[0144] The sum of the DC voltage corresponding to the AC voltage and the correction value is determined as the first bus voltage.

[0145] According to the compressor control device of the storage device provided in the embodiments of this application, by correcting the rectified DC voltage, the error caused by heavy load can be reduced, further improving the accuracy and precision of subsequent detection and control results, improving the compressor speed control effect, thereby improving the user experience, and is suitable for a variety of application scenarios.

[0146] In some embodiments, the device may further include a fourth processing module for:

[0147] Before correcting the input AC voltage, the AC voltage is collected based on the target duration while the compressor is running.

[0148] According to the compressor control device of the storage device provided in the embodiments of this application, the compressor speed is adjusted by collecting AC voltage at regular intervals. While ensuring the normal and stable operation of the storage device, the energy consumption of the storage device can also be reduced, further improving the user experience.

[0149] The compressor control device of the storage device in the embodiments of this application can be the storage device itself, or a component in the storage device, such as an integrated circuit or a chip.

[0150] The compressor control device of the storage device in this embodiment can be a device with an operating system. This operating system can be Android, iOS, or other possible operating systems; this embodiment does not specifically limit the specific operating system.

[0151] The compressor control device for the storage equipment provided in this application embodiment can achieve... Figures 1 to 3 The various processes implemented in the method implementation examples will not be described again here to avoid repetition.

[0152] This application also provides a storage device.

[0153] The storage devices mentioned in the embodiments of this application can be understood as refrigeration storage devices in a broad sense, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines.

[0154] The storage device includes: a cabinet, a compressor, and a compressor control device for the storage device as described in any of the above embodiments.

[0155] In this embodiment, the cabinet may include one or more compartments for storing food, daily necessities, or other items.

[0156] The compressor is located in the cabinet.

[0157] A compressor is a driven fluid used to raise low-pressure gas to high-pressure gas, thereby achieving the refrigeration function.

[0158] The compressor control device of the storage device is electrically connected to the compressor and is used to execute the compressor control method of the storage device as described in any of the above embodiments.

[0159] According to the storage device provided in the embodiments of this application, when the first bus voltage is less than the target threshold, the actual speed of the compressor is controlled based on the limited speed calculated from the first bus voltage and the original set speed of the compressor.
