As a household appliance, air conditioners are frequently used for temperature regulation, and their power consumption is increasingly attracting users' attention. Energy-saving operation mode is a mode that users can set via remote control when using the air conditioner, which can be entered during either cooling or heating. When energy-saving operation mode is entered, the air conditioner system automatically determines the current operating mode and whether the desired temperature has been reached, and then executes the corresponding operating logic. Although energy-saving operation mode control methods exist, the set energy-saving temperature in existing air conditioner energy-saving operation modes is usually limited to a fixed value, resulting in a poor user experience.

Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0047] It should be noted that the terms "first," "second," etc., in the specification and accompanying drawings of this invention are used to distinguish similar users and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0048] The following is a detailed description of embodiments of the air conditioner energy-saving operation control method based on current limiting as described in this invention. Figure 1 The diagram shown is a flowchart of the energy-saving operation control method for air conditioners based on current limiting provided by the present invention. The specific implementation process includes the following steps:

[0049] Step 101: Obtain the actual ambient temperature of the air conditioner in the current operating mode.

[0050] In this embodiment of the invention, the current operating mode includes, but is not limited to, the air conditioner's cooling operating mode and the air conditioner's heating operating mode. The actual ambient temperature may refer to the ambient temperature of the space where the air conditioner is located, which can be obtained through a preset temperature sensor or the like in the current operating mode.

[0051] Step 102: When the actual ambient temperature is within the preset target temperature range and the air conditioner is detected to have entered energy-saving mode, determine the compensation temperature value corresponding to the current operating mode; based on the actual set temperature and the compensation temperature value, obtain the target set temperature; wherein, different types of current operating modes correspond to different compensation temperature values.

[0052] Specifically, the target temperature range can refer to an ambient temperature range that requires temperature compensation, set for the ambient temperature. The target temperature range includes a first target temperature range corresponding to the air conditioner in cooling mode and a second target temperature range corresponding to the air conditioner in heating mode. For example, in cooling mode, the first target temperature range can be <27℃; in heating mode, the second target temperature range can be >23℃. After obtaining the actual ambient temperature of the air conditioner in the current operating mode, the type of operating mode corresponding to the current operating mode can be determined. If the type of operating mode is cooling mode, the actual ambient temperature is compared with the first target temperature range to obtain a first comparison result; if the type of operating mode is heating mode, the actual ambient temperature is compared with the second target temperature range to obtain a second comparison result; based on the first comparison result or the second comparison result, it is determined whether the actual ambient temperature is within the preset target temperature range.

[0053] Additionally, it should be noted that in cooling mode, if the actual ambient temperature is ≥27℃; or in heating mode, if the actual ambient temperature is >23℃, temperature compensation will not be performed. Instead, energy-saving control will be implemented directly through current limiting. Specifically, in cooling mode, because the actual ambient temperature is high (≥27℃), temperature compensation is not performed. Since the ambient temperature is already high, if both the set temperature and the shutdown temperature are compensated by 1.5℃, the air conditioner may shut down immediately upon entering energy-saving mode, failing to provide cooling. Therefore, when the actual ambient temperature is ≥27℃ in cooling mode, temperature compensation is not performed. Similarly, in heating mode, because the actual ambient temperature is low (>23℃), temperature compensation is not performed. Since the ambient temperature is already low, if both the set temperature and the shutdown temperature are subtracted by 1.5℃, the air conditioner may shut down immediately upon entering energy-saving mode, failing to provide heating. Therefore, when the actual ambient temperature is ≤23℃, temperature compensation is not performed. The 1.5℃ mentioned here is the compensation temperature value. The compensation temperature value is not limited to the listed 1.5℃ and can be determined according to the actual situation. The target temperature range is also not limited to the temperature ranges listed above and can also be determined according to the actual situation. That is, after obtaining the actual ambient temperature of the air conditioner in the current operating mode, if the actual ambient temperature is not within the preset target temperature range and the air conditioner is detected to have entered energy-saving mode, the current limit value and its current limiting coefficient corresponding to the air conditioner can be obtained. Based on the current limit value and its current limiting coefficient, the target current corresponding to the air conditioner is determined, and the air conditioner is controlled to operate in energy-saving mode based on the target current and the input actual set temperature.

[0054] In this step, the compensation temperature value includes a cooling compensation temperature value and a heating compensation temperature value. The specific implementation process for determining the compensation temperature value corresponding to the current operating mode includes: when the current operating mode is a cooling operating mode, determining the cooling compensation temperature value corresponding to the actual ambient temperature; wherein the cooling compensation temperature value is a preset positive value; or, when the current operating mode is a heating operating mode, determining the heating compensation temperature value corresponding to the actual ambient temperature; wherein the heating compensation temperature value is a preset negative value.

[0055] The target set temperature can be obtained by adding the compensation temperature value to the actual set temperature. For example, in the cooling mode of an air conditioner, the actual set temperature includes: an input set cooling temperature of 20℃ and a preset temperature to stop at 18.5℃, with a cooling compensation temperature value of 1.5℃. Therefore, the target set temperature in the cooling mode can be calculated to include a target set cooling temperature of 21.5℃ and a target temperature to stop at 20℃. Figure 3 As shown, 301 corresponds to the set cooling temperature, 302 corresponds to the temperature reached and the shutdown temperature value, 303 corresponds to the target set cooling temperature, and 304 corresponds to the target temperature reached and the shutdown temperature value. In cooling mode, the shutdown temperature is reached when the cooling operating temperature reaches the target temperature reached and the shutdown temperature value 304, at which point the air conditioner stops. In heating mode, the actual set temperature includes: an input set cooling temperature of 30℃ and a preset temperature reached and the shutdown temperature value of 28.5℃. The heating compensation temperature value is -1.5℃. Therefore, calculations show that the target set temperature in heating mode includes a target set heating temperature of 28.5℃ and a target temperature reached and the shutdown temperature value of 27℃. For example... Figure 4 As shown, 401 corresponds to the set heating temperature, 402 corresponds to the temperature reached and the shutdown temperature value; 403 corresponds to the target set heating temperature, and 404 corresponds to the target temperature reached and the shutdown temperature value. In heating mode, the shutdown temperature is reached when the heating operating temperature reaches the target temperature reached and the shutdown temperature value 404, at which point the air conditioner is controlled to stop. That is, the temperature compensation method of this invention includes: increasing the temperature by 1.5°C during cooling operation; simultaneously increasing the temperature reached and the shutdown temperature value by 1.5°C; and decreasing the temperature by 1.5°C during heating operation, simultaneously decreasing the temperature reached and the shutdown temperature value by 1.5°C.

[0056] Step 103: Obtain the current limit value and its current limiting coefficient of the air conditioner at the target set temperature; determine the target current corresponding to the air conditioner based on the current limit value and its current limiting coefficient; control the air conditioner to operate in energy-saving mode based on the target current and the target set temperature.

[0057] In this embodiment of the invention, based on the current limiting value and its current limiting coefficient, a preset current limiting algorithm model can be used to calculate and obtain the target current corresponding to the air conditioner. Further, based on the target current and the target set temperature, the operating frequency corresponding to the air conditioner is determined, and frequency modulation control is performed on the air conditioner based on the operating frequency to enable energy-saving operation. The target current is directly proportional to both the current limiting value and the current limiting coefficient. For example, when the air conditioner enters energy-saving operation mode during operation, the current limiting algorithm model used can be: I0 = I... 限额*A is used to limit the current to obtain a more precise target current. Where A is the current limiting coefficient, and 0 < A < 1; I 限额 This refers to the current limiting value (the current limiting value corresponding to the air conditioner's circuit board). By setting the current limiting coefficient A, the target current I0 can be obtained. By using I0 as the target current for frequency modulation control, the air conditioner operates at this frequency (where the current is I0), effectively saving energy consumption. A detailed comparison of power and energy consumption is as follows: Figure 2 As shown.

[0058] Furthermore, after controlling the air conditioner to operate in energy-saving mode based on the target current and target set temperature, the method further includes: obtaining the actual time during which the air conditioner operates in energy-saving mode according to the target current and target set temperature; if the actual time reaches or exceeds a preset time threshold and the air conditioner has not reached the operating range corresponding to the target set temperature, increasing the magnitude of the current limiting coefficient based on a preset number of adjustment steps to obtain a new current limiting coefficient; determining a new target current corresponding to the air conditioner based on the current limiting value and its new current limiting coefficient, and controlling the air conditioner to operate in energy-saving mode based on the new target current and the target set temperature.

[0059] For example, when an air conditioner enters energy-saving operation mode, it first determines the temperature: In cooling mode, the actual ambient temperature is ≥27℃; in heating mode, the actual ambient temperature is ≤23℃. In cooling mode, because the temperature is already high, no temperature compensation is performed. If the set temperature and the temperature-reaching shutdown time are both compensated by 1.5℃, the unit might shut down immediately upon entering energy-saving mode, failing to provide cooling. Therefore, when cooling is ≥27℃, no temperature compensation is performed (this compensation is adding 1.5℃). In heating mode, because the temperature is already low, no temperature compensation is performed. If the set temperature and the temperature-reaching shutdown time are both subtracted by 1.5℃, the unit might shut down immediately upon entering energy-saving mode, failing to provide heating. Therefore, when heating is ≤23℃, no temperature compensation is performed (this compensation is subtracting 1.5℃). Therefore, when the temperature is within the above ranges, only current limiting is applied, reducing the maximum operating power and extending the time to reach the desired temperature, thereby achieving energy-saving goals. Where I0 = I 限额*A. This current limiting algorithm model can be used to limit the current to obtain a more accurate target current. When entering the temperature-reaching range, it operates in the temperature-reaching mode; the air conditioner continues to run, and stops when entering the temperature-reaching shutdown range. If the air conditioner cannot enter the temperature-reaching range at this time, it first determines whether the actual time has reached or exceeded the preset time threshold T (e.g., 40 minutes). If it cannot enter the temperature-reaching range (e.g., 20℃-21.5℃ or 27℃-28.5℃) within the preset time threshold T (e.g., 40 minutes), the current limiting coefficient is increased by 5% increments. When it enters the temperature-reaching range, the current limiting coefficient is no longer increased, and it operates at the corresponding current limiting coefficient for energy saving. When operating in cooling mode with an actual ambient temperature <27℃, or in heating mode with an actual ambient temperature >23℃, upon entering energy-saving mode, temperature compensation is first performed. The set temperature is then adjusted according to the compensated value. For temperature compensation, cooling increases by +1.5℃, and the shutdown temperature is also increased by +1.5℃; heating decreases by -1.5℃, and the shutdown temperature is adjusted downwards by -1.5℃. The operating temperature before cooling compensation is as follows: Figure 3 (a) Compared with the compensated operating temperature, as shown in Figure 3 (b): Operating temperature before heating compensation, as shown in the figure Figure 4 (a) Compared with the compensated operating temperature, as shown in Figure 4 (b). T is the actual set temperature. After temperature compensation, it operates in a current-limited mode, thereby achieving energy saving at different temperatures.

[0060] The present invention provides an energy-saving operation control method for air conditioners based on current limiting. This method determines a compensation temperature value corresponding to the current operating mode based on the actual ambient temperature of the air conditioner in the current operating mode, obtains a target set temperature based on the actual set temperature and the compensation temperature value, then acquires the current limiting value and its limiting coefficient of the air conditioner at the target set temperature, determines the target current of the air conditioner based on the current limiting value and its limiting coefficient, and controls the energy-saving operation of the air conditioner based on the target current and the target set temperature. This invention can improve the control efficiency of energy-saving operation of air conditioners through temperature compensation and current frequency regulation, effectively reducing energy consumption and improving the user experience.
