[0045] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0046] Reference Figure 1 , Figure 1 A schematic diagram of the device structure for determining the performance deviation range of components in the hardware operating environment involved in the embodiments of the present invention.

[0047] like Figure 1As shown, the device for determining the performance deviation range of the components may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen, and optionally, it may also include a standard wired interface or a wireless interface. In this invention, the wired interface of the user interface 1003 may be a USB interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be a high-speed random access memory (RAM) or a non-volatile memory (NVM), such as a disk storage device. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0048] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the device for determining the range of performance deviations of components. It may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0049] like Figure 1 As shown, the memory 1005, which is identified as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a component performance deviation range determination program.

[0050] exist Figure 1 In the component performance deviation range determination device shown, the network interface 1004 is mainly used to connect to the backend server and communicate data with the backend server; the user interface 1003 is mainly used to connect to the user equipment; the component performance deviation range determination device calls the component performance deviation range determination program stored in the memory 1005 through the processor 1001 and executes the component performance deviation range determination method provided in the embodiment of the present invention.

[0051] Based on the above hardware structure, an embodiment of the method for determining the performance deviation range of components according to the present invention is proposed.

[0052] Reference Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the method for determining the performance deviation range of components according to the present invention, which presents the first embodiment of the method for determining the performance deviation range of components according to the present invention.

[0053] Step S10: Obtain the energy efficiency-related components of the target device and find the initial performance deviation range corresponding to the energy efficiency-related components.

[0054] It should be understood that the execution subject of this embodiment is the component performance deviation range determination device. The component performance deviation range determination device may be an electronic device such as a computer and a server, or other devices that can achieve the same or similar functions. This embodiment does not limit this.

[0055] It should be noted that the target device can be preset by the user and can be a household appliance such as an air conditioner or a television. In this embodiment and other embodiments, an air conditioner is used as an example for illustration.

[0056] Energy efficiency-related components refer to parts that affect the energy efficiency indicators of the target equipment. Examples include indoor unit heat exchangers, outdoor unit heat exchangers, indoor unit fans, outdoor unit fans, and compressors, which are energy efficiency-related components of air conditioners. The energy efficiency indicator is the Annual Performance Factor (APF).

[0057] It should be understood that components of the same type cannot have completely identical performance; there will always be performance deviations. In this embodiment and other embodiments, the performance deviation range is used to represent the performance deviation of the components.

[0058] Step S20: Obtain the test results of the energy efficiency test based on the initial performance deviation range, and determine the current energy efficiency index deviation value based on the test results.

[0059] It should be noted that the test results can be the weighted proportion of the influence of energy efficiency influencing factors on the operating condition variables under different operating conditions, and this embodiment does not impose any restrictions on this.

[0060] It should be understood that obtaining the test results of energy efficiency tests based on the initial performance deviation range can be achieved by obtaining the calculated results of the energy efficiency test, normalizing the calculated results, and calculating the range of each energy efficiency influencing factor under each operating condition according to the Taguchi method. By normalizing the range of the same energy efficiency influencing factor under different operating conditions, the influence weight ratio of the energy efficiency influencing factor on the operating condition variables under different operating conditions can be obtained, and the influence weight ratio can be used as the test result.

[0061] It should be noted that the energy efficiency index deviation value can be the difference between the current APF and the standard APF. The standard APF can be preset by the user, and this embodiment does not impose any restrictions on it.

[0062] It is understandable that determining the current energy efficiency index deviation value based on the test results can be achieved by extracting test data, obtaining test data, and then determining the current energy efficiency index deviation value based on the test data.

[0063] Step S30: Adjust the initial performance deviation range according to the current energy efficiency index deviation value to obtain the target performance deviation range.

[0064] It should be noted that when all energy efficiency-related components are within the target performance deviation range, the energy consumption index of the target equipment meets the usage requirements.

[0065] It should be understood that adjusting the initial performance deviation range based on the current energy efficiency index deviation value to obtain the target performance deviation range can be achieved by determining the performance improvement amount based on the current energy efficiency index deviation value, and then determining the target performance deviation range based on the performance improvement amount and the initial performance deviation range.

[0066] In the first embodiment, the method of acquiring energy efficiency-related components of the target device, finding the initial performance deviation range corresponding to the energy efficiency-related components, obtaining the test results of energy efficiency tests based on the initial performance deviation range, determining the current energy efficiency index deviation value based on the test results, and adjusting the initial performance deviation range based on the current energy efficiency index deviation value to obtain the target performance deviation range is disclosed. In this embodiment, the current energy efficiency index deviation value corresponding to the initial performance deviation range is determined by the test results of the energy efficiency test, and the initial performance deviation range is adjusted based on the current energy efficiency index deviation value, thereby optimizing the performance deviation range of energy efficiency-related components to improve the product performance of the target device.

[0067] Reference Figure 3 , Figure 3 This is a flowchart illustrating the second embodiment of the method for determining the performance deviation range of components according to the present invention. Based on the above... Figure 2 The first embodiment shown presents a second embodiment of the method for determining the performance deviation range of components according to the present invention.

[0068] In the second embodiment, before step S20, the method further includes:

[0069] Step S110: Determine the test parameter table based on the energy efficiency-related components and the initial performance deviation range.

[0070] It should be understood that determining the test parameter table based on energy efficiency-related components and the initial performance deviation range can involve determining the upper performance threshold, performance benchmark value, and lower performance threshold based on the initial performance deviation range, and then determining the test parameter table based on the upper performance threshold, performance benchmark value, lower performance threshold, and the energy efficiency influencing factors corresponding to the energy efficiency-related components. These energy efficiency influencing factors can be factors that affect energy efficiency performance, such as the indoor unit heat exchange area of ​​the indoor unit heat exchanger, the outdoor unit heat exchange area of ​​the outdoor unit heat exchanger, the indoor unit airflow of the indoor unit fan, the outdoor unit airflow of the outdoor unit fan, and the isentropic efficiency of the compressor.

[0071] For ease of understanding, Table 1 is used as a reference, but it does not limit this scheme. Table 1 is the test parameter table, where the column containing energy efficiency influencing factors represents the upper performance threshold of the energy efficiency influencing factor (1), the performance benchmark value (2), and the lower performance threshold (3). This embodiment includes 5 energy efficiency influencing factors. For 3 factors (indoor unit airflow, outdoor unit airflow, and isentropic efficiency), the upper performance threshold, the performance benchmark value, and the lower performance threshold are selected. For 2 factors (indoor unit heat exchange area and outdoor unit heat exchange area), the performance benchmark value and the lower performance threshold are selected. If a comprehensive test is conducted, the number of tests required under a single operating condition is 3. 3 ×2 2 = 108 times. In this embodiment, a representative combination of experiments is selected according to the orthogonal experimental method. The results of these experiments are analyzed to understand the overall experimental situation. The specific selection is shown in Table 1. After orthogonal design, only 9 sets of experiments are needed to characterize the overall experiment under a single operating condition. Analysis shows that the operating condition variables simulated by each set of experiments are the result of the simultaneous deviation of multiple factors. When analyzing a certain performance parameter of a certain factor, only 3 sets of relevant experimental data are needed to characterize the influence of the factor level on the operating condition variables. For example, when the indoor unit air volume is at the upper limit threshold, the results of experiments 1, 2, and 3 are selected for calculation; when the outdoor unit heat exchange area is at the lower limit threshold, the results of experiments 1, 6, and 7 are selected for calculation.

[0073]

[0074] Step S120: Determine the test condition table based on the target equipment, and generate a test item table based on the test condition table and the test parameter table.

[0075] It should be understood that the impact of energy efficiency influencing factors varies under different operating conditions. Therefore, it is necessary to conduct tests on energy efficiency influencing factors under different test conditions.

[0076] In practical implementation, for example, the test condition table for air conditioners includes rated cooling condition, intermediate cooling condition, rated heating condition, and intermediate heating condition.

[0077] It should be understood that each test item in the test item table can be performed under various test conditions and various test parameters, and this embodiment does not limit this.

[0078] Accordingly, step S20 includes:

[0079] Step S20': Obtain the test results of the energy efficiency test based on the test item table, and determine the current energy efficiency index deviation value based on the test results.

[0080] It should be understood that obtaining the test results of energy efficiency tests based on the test item table can be achieved by obtaining the calculation results of energy efficiency tests based on the test item table, normalizing the calculation results, and calculating the range of each energy efficiency influencing factor under each operating condition according to the Taguchi method. By normalizing the range of the same energy efficiency influencing factor under different operating conditions, the influence weight ratio of the energy efficiency influencing factor on the operating condition variables under different operating conditions can be obtained, and the influence weight ratio can be used as the test result.

[0081] In the second embodiment, by first determining the test parameter table, then determining the test operating condition table, then generating the test item table based on the test parameter table and the test operating condition table, and finally obtaining the test results of the energy efficiency test based on the test item table, the test items can be simplified and the test efficiency can be improved.

[0082] Reference Figure 4 , Figure 4 This is a flowchart illustrating the third embodiment of the method for determining the performance deviation range of components according to the present invention. Based on the above... Figure 2 The first embodiment shown presents a third embodiment of the method for determining the performance deviation range of components according to the present invention.

[0083] In the third embodiment, step S10 includes:

[0084] Step S101: Obtain the equipment information of the target device, and determine the components of the device based on the equipment information.

[0085] It should be noted that the equipment information may include equipment manufacturer information and equipment model information, etc. In this embodiment and other embodiments, the equipment model information is used as an example for explanation.

[0086] Equipment components refer to the components that make up the target equipment. For example, the equipment components corresponding to an air conditioner include the indoor heat exchanger, the outdoor heat exchanger, the indoor fan, the outdoor fan, the compressor, the electronic expansion valve, and the four-way valve, etc. This embodiment does not limit these components.

[0087] It should be understood that obtaining the device information of the target device can be done by searching for the corresponding device information in a preset storage area. The device information in the preset storage area can be pre-stored by the target device manufacturer, and this embodiment does not impose any restrictions on this.

[0088] Step S102: Select energy efficiency-related components from the components of the equipment, and obtain the energy efficiency influencing factors corresponding to the energy efficiency-related components.

[0089] It should be understood that selecting energy-efficiency-related components from equipment components can involve obtaining the component identifiers of the equipment components and determining the energy-efficiency-related components based on these identifiers. The component identifiers are used to indicate the function of the component.

[0090] It should be noted that energy efficiency influencing factors can be factors that affect energy efficiency performance, such as the indoor heat exchange area of ​​the indoor heat exchanger, the outdoor heat exchange area of ​​the outdoor heat exchanger, the indoor air volume of the indoor fan, the outdoor air volume of the outdoor fan, and the isentropic efficiency of the compressor.

[0091] Step S103: Find the initial performance deviation range corresponding to the energy efficiency influencing factors.

[0092] It should be understood that finding the initial performance deviation range corresponding to the energy efficiency influencing factors can be done by looking up the initial performance deviation range corresponding to the energy efficiency influencing factors in a preset performance deviation range table. The preset performance deviation range table contains the correspondence between energy efficiency influencing factors and initial performance deviation ranges, and this correspondence can be preset by the user; this embodiment does not impose any restrictions on it.

[0093] For example, the initial performance deviation range of the indoor unit heat exchange area is -2%, the initial performance deviation range of the outdoor unit heat exchange area is -2%, the initial performance deviation range of the indoor unit air volume is ±5%, the initial performance deviation range of the outdoor unit air volume is ±3%, and the initial performance deviation range of the isentropic efficiency is ±2%.

[0094] In the third embodiment, the method of obtaining equipment information of the target device, determining the components of the device based on the equipment information, selecting energy-efficiency related components from the components of the device, obtaining the energy efficiency influencing factors corresponding to the energy efficiency related components, and finding the initial performance deviation range corresponding to the energy efficiency influencing factors are disclosed. Since this embodiment determines the energy efficiency related components based on the components of the device and determines the initial performance deviation range based on the energy efficiency influencing factors corresponding to the energy efficiency related components, the accuracy of the initial performance deviation range can be improved.

[0095] In the third embodiment, step S20 includes:

[0096] Step S201: Obtain the test results of the energy efficiency test based on the initial performance deviation range.

[0097] It should be noted that the test results can be the weighted proportion of the influence of energy efficiency influencing factors on the operating condition variables under different operating conditions, and this embodiment does not impose any restrictions on this.

[0098] Step S202: Establish an energy efficiency analysis model based on the test results, and determine the current energy efficiency index deviation value based on the initial performance deviation range and the energy efficiency analysis model.

[0099] It should be noted that the energy efficiency analysis model can be used to determine the deviation value of energy efficiency index based on the performance deviation range, and this embodiment does not limit it in this way.

[0100] It should be understood that establishing an energy efficiency analysis model based on test results can involve extracting information from the test results, obtaining energy efficiency weight information, and determining the current energy efficiency index deviation value based on the energy efficiency weight information.

[0101] Furthermore, in order to improve the reliability of the energy efficiency analysis model, step S202 includes:

[0102] Based on the test results, a capability weight table and a power weight table are generated, and parameter analysis is performed on the capability weight table and the power weight table.

[0103] Based on the analysis results, a working condition weight table is determined, and an energy efficiency analysis model is established based on the capacity weight table, the power weight table, and the working condition weight table.

[0104] The current energy efficiency index deviation value is determined based on the initial performance deviation range and the energy efficiency analysis model.

[0105] It should be noted that the capacity weight table can be the weight percentage of each energy efficiency factor on the equipment's operating capacity.

[0106] For ease of understanding, please refer to Table 2 for explanation, but this does not limit the scope of this scheme. Table 2 is the capability weight table.

[0107] Table 2 Capability Weighting Table

[0108]

[0109] It should be noted that the power weight table can be the weight percentage of each energy efficiency factor on the operating power of the equipment.

[0110] For ease of understanding, please refer to Table 3 for explanation, but this does not limit the scope of this scheme. Table 3 is the power weighting table.

[0111] Table 3 Power Weighting Table

[0112]

[0113] Understandably, based on the capacity and power weight tables, the indoor unit side (heat exchange area and airflow) has the greatest impact on the equipment's operating capacity under the four operating conditions, while the compressor's isentropic efficiency has the most significant impact on the equipment's operating power under the four operating conditions. Looking at the operating condition weights, the capacity of the front heating condition is most significantly affected by various factors, while the capacity of the front cooling condition responds more slowly to changes in these factors. Similarly, the power of the intercooling condition is greatly affected by the combined effects of various factors, and again, the power of the front cooling condition responds more slowly to changes in these factors.

[0114] It should be noted that the operating condition weight table can be the weight percentage of the influence of each operating condition's capacity and power on the APF deviation.

[0115] For ease of understanding, please refer to Table 4 for explanation, but this does not limit the scope of this scheme. Table 4 is the working condition weight table.

[0116] Table 4 Working Condition Weight Table

[0117]

[0118] It should be understood that establishing an energy efficiency analysis model based on the capacity weight table, power weight table, and operating condition weight table can be done by ranking the impact of changes in the above independent variable factors (indoor / outdoor unit air volume, indoor / outdoor unit heat exchange area, compressor isentropic efficiency) on the capacity / power of each operating condition, as well as ranking the impact of the capacity / power of each operating condition on the overall APF. A correlation polynomial between the changes in the independent variable factors and the changes in the overall APF can be fitted.

[0119] The polynomial form is a quinary linear normalized polynomial:

[0120] vA+wB+xC+yD+zE=APF

[0121] In the formula, A is the outdoor unit air volume, B is the indoor unit air volume, C is the compressor isentropic efficiency, D is the outdoor unit heat exchange area, and E is the indoor unit heat exchange area. The baseline mean (normalized relative mean deviation) of each unknown variable is 1. v, w, x, y, and z are constants. The formula has been normalized, and the result is the unbiased mean of the APF, with an initial mean value (normalized relative mean deviation) of 1.

[0122] Through iterative calculation, the correlation polynomial is obtained:

[0123] 0.0499A+01873B+0.3064C+0.1878D+0.2685E=APF

[0124] The calculated correlation polynomial is used as the energy efficiency analysis model.

[0125] It should be noted that the deviation value of the energy efficiency index can be the APF deviation, and this embodiment does not limit it.

[0126] Understandably, the current energy efficiency index deviation value can be determined based on the initial performance deviation range and the energy efficiency analysis model, as shown in Table 5.

[0127] Table 5 APF Deviation Table

[0128]

[0129] In the third embodiment, the method of obtaining test results of energy efficiency tests based on the initial performance deviation range is disclosed. An energy efficiency analysis model is established based on the test results, and the current energy efficiency index deviation value is determined based on the initial performance deviation range and the energy efficiency analysis model. Since the energy efficiency analysis model is introduced in this embodiment to determine the energy efficiency index deviation value corresponding to the initial performance deviation range, the accuracy of the energy efficiency index deviation value can be improved.

[0130] In the third embodiment, step S30 includes:

[0131] Step S301: Obtain the target energy efficiency index deviation range of the target device, and determine the energy efficiency index difference based on the current energy efficiency index deviation value and the target energy efficiency index deviation range.

[0132] It should be noted that the deviation range of the target energy efficiency index can be preset by the user. In this embodiment and other embodiments, the deviation range of the target energy efficiency index is illustrated by ±2%.

[0133] It should be understood that, according to Table 5, the current energy efficiency index deviation ranges from -2.6% to +1.4%, with -2.6% exceeding -2%, resulting in an energy efficiency index difference of 0.6%. This means that the APF (Average Power Factor) needs to be improved by 0.6%.

[0134] Step S302: Adjust the initial performance deviation range according to the energy efficiency index difference and the energy efficiency analysis model to obtain the target performance deviation range.

[0135] It should be understood that adjusting the initial performance deviation range based on the energy efficiency index difference and the energy efficiency analysis model to obtain the target performance deviation range can be achieved by determining the performance improvement amount based on the energy efficiency index difference and the energy efficiency analysis model, and generating the target performance deviation range based on the initial performance deviation range and the performance improvement amount.

[0136] For ease of understanding, the performance improvement can be shown in Table 6.

[0137] Table 6 Performance Improvement Table

[0138]

[0139] Among them, 0.0499a+01873b+0.3064c+0.1878d+0.2685e=0.6%.

[0140] Furthermore, considering that improving the performance of components requires increasing costs, in order to select the target performance deviation range with the highest cost-effectiveness, step S302 includes:

[0141] Obtain the cost score of the energy efficiency-related components;

[0142] The initial performance deviation range is adjusted based on the cost score and the energy efficiency index difference to obtain the target performance deviation range.

[0143] It should be noted that the cost score can be used to represent the cost required to improve the performance of energy-efficient related components; the higher the cost score, the higher the cost.

[0144] It should be understood that the initial performance deviation range is adjusted based on the cost score and the difference in energy efficiency indicators. The target performance deviation range can be obtained by selecting a cost-effective performance improvement combination based on the actual economic cost.

[0145] In the third embodiment, the method of obtaining the target energy efficiency index deviation range of the target device is disclosed. The energy efficiency index difference is determined based on the current energy efficiency index deviation value and the target energy efficiency index deviation range. The initial performance deviation range is adjusted based on the energy efficiency index difference and the energy efficiency analysis model to obtain the target performance deviation range. Since in this embodiment, the initial performance deviation range is adjusted based on the energy efficiency index difference between the current energy efficiency index deviation value and the target energy efficiency index deviation range through the energy efficiency analysis model, the reliability of the performance deviation adjustment can be guaranteed.

[0146] Furthermore, this embodiment of the invention also proposes a storage medium storing a component performance deviation range determination program, which, when executed by a processor, implements the steps of the component performance deviation range determination method described above.

[0147] In addition, refer to Figure 5 The present invention also proposes a component performance deviation range determination device, which includes: an acquisition module 10, a determination module 20 and an adjustment module 30;

[0148] The acquisition module 10 is used to acquire energy efficiency-related components of the target device and find the initial performance deviation range corresponding to the energy efficiency-related components.

[0149] It should be noted that the target device can be preset by the user and can be a household appliance such as an air conditioner or a television. In this embodiment and other embodiments, an air conditioner is used as an example for illustration.

[0150] Energy efficiency-related components refer to parts that affect the energy efficiency indicators of the target equipment. Examples include indoor unit heat exchangers, outdoor unit heat exchangers, indoor unit fans, outdoor unit fans, and compressors, which are energy efficiency-related components of air conditioners. The energy efficiency indicator is the Annual Performance Factor (APF).

[0151] It should be understood that components of the same type cannot have completely identical performance; there will always be performance deviations. In this embodiment and other embodiments, the performance deviation range is used to represent the performance deviation of the components.

[0152] The determining module 20 is used to obtain the test results of the energy efficiency test based on the initial performance deviation range, and determine the current energy efficiency index deviation value based on the test results.

[0153] It should be noted that the test results can be the weighted proportion of the influence of energy efficiency influencing factors on the operating condition variables under different operating conditions, and this embodiment does not impose any restrictions on this.

[0154] It should be understood that obtaining the test results of energy efficiency tests based on the initial performance deviation range can be achieved by obtaining the calculated results of the energy efficiency test, normalizing the calculated results, and calculating the range of each energy efficiency influencing factor under each operating condition according to the Taguchi method. By normalizing the range of the same energy efficiency influencing factor under different operating conditions, the influence weight ratio of the energy efficiency influencing factor on the operating condition variables under different operating conditions can be obtained, and the influence weight ratio can be used as the test result.

[0155] It should be noted that the energy efficiency index deviation value can be the difference between the current APF and the standard APF. The standard APF can be preset by the user, and this embodiment does not impose any restrictions on it.

[0156] It is understandable that determining the current energy efficiency index deviation value based on the test results can be achieved by extracting test data, obtaining test data, and then determining the current energy efficiency index deviation value based on the test data.

[0157] The adjustment module 30 is used to adjust the initial performance deviation range according to the current energy efficiency index deviation value to obtain the target performance deviation range.

[0158] It should be noted that when all energy efficiency-related components are within the target performance deviation range, the energy consumption index of the target equipment meets the usage requirements.

[0159] It should be understood that adjusting the initial performance deviation range based on the current energy efficiency index deviation value to obtain the target performance deviation range can be achieved by determining the performance improvement amount based on the current energy efficiency index deviation value, and then determining the target performance deviation range based on the performance improvement amount and the initial performance deviation range.

[0160] In this embodiment, the process of acquiring energy efficiency-related components of the target device, finding the initial performance deviation range corresponding to the energy efficiency-related components, obtaining the test results of energy efficiency tests based on the initial performance deviation range, determining the current energy efficiency index deviation value based on the test results, and adjusting the initial performance deviation range based on the current energy efficiency index deviation value to obtain the target performance deviation range is disclosed. This embodiment determines the current energy efficiency index deviation value corresponding to the initial performance deviation range through the test results of energy efficiency tests, and adjusts the initial performance deviation range based on the current energy efficiency index deviation value, thereby optimizing the performance deviation range of energy efficiency-related components to improve the product performance of the target device.
