In addition, the embodiments provided below are partial embodiments for implementing the present disclosure, rather than all embodiments for implementing the present disclosure.

[0028] For example, the air volume compensation control method provided in the embodiments of the present disclosure includes a series of steps, but the air volume compensation control method provided in the embodiments of the present disclosure is not limited to the recited steps. Similarly, the air volume compensation control device provided in the embodiments of the present disclosure includes a series of units, but the device provided in the embodiments of the present disclosure is not limited to including the expressly recited units, and may also include units required for obtaining relevant information or processing based on the information.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this disclosure belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0030] It can be understood that in the specific implementation manner of this application, when it comes to relevant data, when the embodiments in this application are applied to specific products or technologies, user permission or consent is required, and the collection, use, and processing of relevant data need to comply with the relevant laws, regulations, and standards of the relevant countries and regions.

[0031] Figure 1 The flowchart of the air volume compensation control method according to an embodiment of the present application is schematically shown. The execution subject of the air volume compensation control method may be an air volume compensation control device with processing capabilities. The air volume compensation control device may be disposed in devices such as heat pump devices, mobile phones, computers, smart watches, and other household electrical appliances. The air volume compensation control device may at least include a memory and a processor.

[0032] In a specific embodiment of the present application, the air volume compensation control device, which is the execution subject of the air volume compensation control method, is specifically arranged in the heat pump device. The air volume compensation control device may include a processor and a memory. A computer program is stored in the memory, and the processor can read the computer program stored in the memory to execute the methods of the embodiments of the present application. The heat pump device may be a heat pump water heater.

[0033] As Figure 1 shown, the air volume compensation control method may include steps S110 to S130.

[0034] Step S110, receiving the outlet water temperature value;

[0035] Step S120, when the rising rate of the outlet water temperature value is lower than the preset rate, determining the air volume attenuation degree of the heat pump device, where the rising rate is the ratio of the change value of the outlet water temperature within the preset time to the preset time;

[0036] Step S130, based on the air volume attenuation degree, controlling the fan speed to be increased to the preset gear so that the energy efficiency ratio of the heat pump device is greater than the preset value.

[0037] By setting a water temperature sensor, the outlet water temperature value detected by the water temperature sensor can be received in real time. The outlet water temperature value is the water temperature of the water output by the heat pump device. The change value of the outlet water temperature can be calculated according to the outlet water temperature value received within the preset time. For example, the preset time is the time between moment A and moment B, and the temperature difference is obtained by subtracting the outlet water temperature value at moment B from the outlet water temperature value at moment A. This temperature difference is the change value of the outlet water temperature within the preset time. Further, calculating the ratio of the change value of the outlet water temperature to the preset time is the rising rate of the outlet water temperature value.

[0038] Further, a preset rate is specified in advance (this preset rate can be set according to the actual situation, and the present application does not make specific limitations on this). Comparing the calculated rising rate with this preset rate, when the rising rate is lower than the preset rate, further determining the air volume attenuation degree of the heat pump device. The air volume attenuation degree is used to reflect the attenuation degree of the fan air volume in the heat pump device.

[0039] Further, the preset gear corresponding to the current air volume attenuation degree can be determined, and the fan in the heat pump device is controlled to be increased to this preset gear. Thus, according to the air volume attenuation degree, the fan is controlled to be increased to the corresponding preset gear. Increasing to the preset gear can make the energy efficiency ratio of the heat pump device greater than the preset value, and then effectively avoid various problems caused by air volume attenuation.

[0040] In summary, in the manner of the embodiments of the present application, when the rising rate of the outlet water temperature value is lower than the preset rate, the air volume attenuation degree of the heat pump device is determined, and based on the air volume attenuation degree, the fan speed is controlled to be increased to the preset gear, so that the energy efficiency ratio of the heat pump device is greater than the preset value, which can improve the control reliability of the fan in the heat pump device and enhance the heating capacity, energy efficiency and stability of the heat pump device.

[0041] The following describes Figure 1 Specific optional embodiments of each step when performing air volume compensation control in the embodiment.

[0042] In one embodiment, referring to Figure 2 , in step S120, to determine the air volume attenuation degree of the heat pump device, it may include: step S210, calculating the rate deviation degree between the rising rate and the preset rate; step S220, determining the air volume attenuation degree of the heat pump device according to the rate deviation degree.

[0043] When the rising rate of the outlet water temperature value is lower than the preset rate, calculate the rate deviation degree between the rising rate and the preset rate. This rate deviation degree can reflect the deviation degree of the rising rate of the outlet water temperature value compared with the preset rate. According to this rate deviation degree, the air volume attenuation degree of the heat pump device can be accurately determined.

[0044] Further, in one embodiment, calculating the rate deviation degree between the rising rate and the preset rate may specifically include: calculating the rate deviation degree according to the formula ΔS = B × |A - B| × 100%, where ΔS refers to the rate deviation degree, A refers to the rising rate, and B refers to the preset rate.

[0045] The applicant found that according to the formula ΔS = B × |A - B| × 100%, the rate deviation degree can be further accurately calculated. The rate deviation degree calculated by this formula can further accurately reflect the deviation degree of the rising rate compared with the preset rate. According to this rate deviation degree, the air volume attenuation degree of the heat pump device can be further accurately determined.

[0046] Optionally, in other embodiments, calculating the rate deviation degree between the rising rate and the preset rate may also be calculated according to other predetermined calculation methods, such as calculating the difference between the rising rate and the preset rate as the rate deviation degree.

[0047] Further, in one embodiment, determining the air volume attenuation degree of the heat pump device according to the rate deviation degree may include the following two optional methods:

[0048] The first method is to determine the air volume attenuation degree corresponding to the degree range where the rate deviation degree is located;

[0049] Alternatively, in the second method, calculate the current deviation degree between the real-time current value and the preset current value of the fan, and determine the air volume attenuation degree corresponding to the degree range where the target deviation degree is located. The target deviation degree is the higher one of the speed deviation degree and the current deviation degree, and the higher the degree range, the higher the corresponding air volume attenuation degree.

[0050] In the first method, directly determining the air volume attenuation degree based on the speed deviation degree can ensure the accuracy of the air volume attenuation degree and improve the reliability of fan control.

[0051] Specifically, first determine the degree range where the speed deviation degree is located, and then determine the air volume attenuation degree corresponding to this degree range. For example, if three predetermined degree ranges are 5% - 10%, 10% - 20%, and over 20%, the air volume attenuation degrees corresponding to these three degree ranges are mild attenuation, moderate attenuation, and severe attenuation respectively, that is, the higher the degree range, the higher the corresponding air volume attenuation degree. Accordingly, if the degree range where the speed deviation degree is located is 5% - 10%, the corresponding air volume attenuation degree is mild attenuation.

[0052] In the second method, further determine the current deviation degree, select the higher one of the speed deviation degree and the current deviation degree as the target deviation degree, and then determine the corresponding air volume attenuation degree according to the target deviation degree, which can further ensure the accuracy of the air volume attenuation degree and thus further improve the reliability of fan control.

[0053] Specifically, receive the real-time current value of the fan in real time, calculate the current deviation degree between the real-time current value and the preset current value of the fan, select the higher one of the speed deviation degree and the current deviation degree as the target deviation degree, first determine the degree range where the target deviation degree is located, and then determine the air volume attenuation degree corresponding to this degree range. For example, if three predetermined degree ranges are 5% - 10%, 10% - 20%, and over 20%, the air volume attenuation degrees corresponding to these three degree ranges are mild attenuation, moderate attenuation, and severe attenuation respectively, that is, the higher the degree range, the higher the corresponding air volume attenuation degree. Accordingly, if the degree range where the target deviation degree is located is 10% - 20%, the corresponding air volume attenuation degree is moderate attenuation.

[0054] Further, in one embodiment, calculating the current deviation degree between the real-time current value and the preset current value of the fan may include: calculating the current deviation degree according to the formula ΔI = Imin × |Icurrent - Imin| × 100%, where ΔI refers to the current deviation degree, Icurrent refers to the real-time current value of the fan, and Imin refers to the preset current value.

[0055] The applicant has found that the degree of current deviation can be further accurately calculated according to the formula ΔI = Imin × |Icurrent - Imin| × 100%, and the degree of current deviation calculated by this formula can further accurately reflect the deviation degree of the real-time current value of the fan compared with the preset current value.

[0056] Optionally, in other embodiments, to calculate the degree of current deviation between the real-time current value and the preset current value of the fan, it can also be calculated according to other predetermined calculation methods. For example, the difference between the real-time current value and the preset current value is calculated as the degree of current deviation.

[0057] In one embodiment, before controlling the fan speed to increase to the preset gear based on the air volume attenuation degree, the method may further include: receiving the real-time current value of the fan; and determining the air volume attenuation degree of the heat pump device when the real-time current value is lower than the preset current value.

[0058] In this embodiment, on the basis of step S120 of the embodiment as Figure 1 shown, the real-time current value of the fan is further received, and when the real-time current value is lower than the preset current value, the air volume attenuation degree of the heat pump device is also determined. That is, in this embodiment, when "the real-time current value of the fan is lower than the preset current value" and / or "the rising rate of the outlet water temperature value is lower than the preset rate", it will trigger the determination of the air volume attenuation degree of the heat pump device, and then further execute the step of adjusting the gear of the fan speed, further ensuring the reliability of fan control.

[0059] In one embodiment, referring to Figure 3 , after controlling the fan speed to increase to the preset gear based on the air volume attenuation degree, it may further include: step S310, receiving the heating capacity and the input power; step S320, calculating the energy efficiency ratio according to the heating capacity and the input power; step S330, when the energy efficiency ratio is greater than or equal to the preset value, maintaining the current operation gear of the fan speed.

[0060] After controlling the fan speed to increase to the preset gear, the energy efficiency ratio (COP) of the heat pump device is monitored in real time. When the energy efficiency ratio is greater than or equal to the preset value, the current operation gear of the fan speed is maintained, thereby further ensuring the reliability of fan control through energy efficiency optimization feedback.

[0061] Among them, the energy efficiency ratio is calculated according to the heating capacity (kW) and the input power (kW) of the heat pump device. Specifically, the product of the heating capacity (kW) and the input power (kW) can be calculated, and this product is used as the energy efficiency ratio of the heat pump device.

[0062] Further, in one embodiment, when the energy efficiency ratio is greater than or equal to a preset value, maintaining the current operating gear of the fan speed may include: when the energy efficiency ratio is less than the preset value, increasing the level of the air volume attenuation degree to obtain an increased target air volume attenuation degree; determining a corresponding target gear according to the target air volume attenuation degree; and controlling the fan speed to increase to the target gear.

[0063] In this embodiment, after calculating the energy efficiency ratio based on the heating capacity and the input power, if the energy efficiency ratio is less than the preset value, the level of the air volume attenuation degree determined in the foregoing steps is increased to obtain a target air volume attenuation degree with an increased level. For example, if the air volume attenuation degree determined in the foregoing embodiment is medium attenuation, when the energy efficiency ratio is less than the preset value, the air volume attenuation degree can be increased by one level to become severe attenuation, and the target air volume attenuation degree after the level increase is severe attenuation.

[0064] Further, a preset gear corresponding to the increased target air volume attenuation degree can be determined as the target gear, and the fan speed is controlled to increase to this target gear, thereby further ensuring the energy efficiency and stability of the heat pump device.

[0065] Further, in this application, for different air volume attenuation degrees, a mapping relationship between the air volume attenuation degree and the corresponding preset gear is specified in advance, and the higher the air volume attenuation degree, the higher the corresponding preset gear. For example, the preset gear corresponding to mild attenuation is A, and when the preset gear is A, the fan speed is increased to 80% - 90% of the rated value; the preset gear corresponding to medium attenuation is B, and when the preset gear is B, the fan speed is increased to 90% - 110% of the rated value; the preset gear corresponding to severe attenuation is C, and when the preset gear is C, the fan speed is increased to 110% - 120% of the rated value.

[0066] Furthermore, in step S130 of the embodiment as Figure 1 shown, when controlling the fan speed to increase to the preset gear based on the air volume attenuation degree, the preset gear corresponding to the air volume attenuation degree can be determined according to this mapping relationship. Also, in the foregoing embodiment, when determining the corresponding target gear according to the target air volume attenuation degree, the preset gear corresponding to the target air volume attenuation degree can be determined according to this mapping relationship as the target gear.

[0067] In addition, an embodiment of this application also provides an air volume compensation control device, and the air volume compensation control device can be applied to a control device.

[0069] For example, the processor 401 can execute the following steps:
