Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an air-conditioning intelligent control method, device, equipment and medium. Background Art

[0002] With the improvement of people's living standards, air-conditioning equipment has entered thousands of households. The use of air conditioners is becoming more and more common, and users' requirements for the comfort of using air conditioners are also getting higher and higher.

[0003] At present, the control method commonly used in air-conditioning systems mainly relies on sensors to monitor indoor and outdoor environmental parameters, such as indoor ambient temperature, outdoor temperature and humidity. These data are transmitted to the air-conditioning control unit. The control unit adjusts the air-conditioning operation mode according to the preset program algorithm, including the working status of the compressor, fan speed and refrigerant flow rate, etc., in order to achieve efficient use of energy while meeting user comfort needs.

[0004] However, due to the limitations of the algorithm, the above control method often fails to achieve the expected energy-saving effect and comfort level in actual operation of the air-conditioning system, which easily leads to energy waste or reduced indoor comfort. The control accuracy needs to be improved, and the adjustment ability is limited when facing complex changes in indoor and outdoor environments, making it difficult to achieve the optimal energy-saving effect. Summary of the invention

[0005] The present invention provides an air-conditioning intelligent control method, device, equipment and medium, which are used to solve the defect that air-conditioning control in the prior art is difficult to achieve the expected energy-saving effect and comfort, resulting in a decrease in indoor comfort, and to achieve precise adjustment of indoor temperature to meet users' precise temperature requirements in different environments.

[0006] The present invention provides an intelligent air-conditioning control method, comprising: receiving an air-conditioning control instruction, detecting the temperature difference between indoor and outdoor ambient temperatures; determining an air-conditioning operation mode, and based on the air-conditioning operation mode, determining whether the temperature difference meets a corresponding preset temperature range, and obtaining a judgment result; based on the judgment result and the air-conditioning operation mode, selecting a corresponding control mode, and controlling the operation according to the selected control mode; wherein the control mode is set in advance based on the positional relationship between the temperature difference and the preset temperature range under different air-conditioning operation modes, and the air-conditioning operation mode is used to characterize the air-conditioning cooling or heating mode.

[0007] It should be noted that by receiving air-conditioning control instructions and detecting the temperature difference between indoor and outdoor ambient temperatures, the control mode is selected according to the air-conditioning cooling or heating mode, taking into account the relationship between the temperature difference and the corresponding preset temperature range, so that the air-conditioning operation is more in line with actual needs, improving energy utilization efficiency as a whole, reducing energy consumption costs, and achieving precise adjustment of indoor temperature, ensuring that the indoor temperature is always kept within a comfortable range, meeting the user's precise temperature needs in different environments.

[0008] According to the present invention, an intelligent air-conditioning control method is provided, which selects a corresponding control mode based on a judgment result and an air-conditioning operation mode, and controls the operation according to the selected control mode, including: when the air-conditioning operation mode is a cooling mode, if the judgment result is that the temperature difference meets the preset temperature range or the temperature difference is greater than the upper limit of the preset temperature range, the control operates in a single-path control mode, and when the temperature difference meets the second energy-saving level, the control operates in a multi-path shunt control mode; wherein, the single-path control mode is used to characterize a mode in which the refrigerant uses a circulation path to adjust the air temperature and humidity, and the multi-path shunt control mode is used to characterize a mode in which the air conditioner distributes the refrigerant to a single path of at least two indoor units through at least two main channels, and the second energy-saving level is determined in advance based on the divided temperature difference range.

[0009] It should be noted that in cooling mode, the control mode is selected according to the relationship between the temperature difference and the preset temperature range, so that the air conditioner can flexibly adjust the operation mode according to the actual temperature changes, ensuring the best cooling effect under various temperature conditions and improving the user's comfort. In addition, when the temperature difference meets the preset temperature range or is greater than the upper limit, for scenarios where the temperature difference is not large or the temperature difference is large and requires rapid cooling, the single-channel control mode is used for rapid cooling, which can reduce unnecessary system complexity and extend the life of the equipment. When the temperature difference meets the second energy-saving level, it switches to the multi-channel shunt control mode to achieve fine control of the evaporators in different areas, further improve the accuracy of temperature regulation, and meet the cooling needs in complex scenarios such as uneven indoor temperature distribution.

[0010] According to the present invention, an intelligent air-conditioning control method is provided, which selects a corresponding control mode based on a judgment result and an air-conditioning operation mode, and controls the operation according to the selected control mode, and also includes: when the air-conditioning operation mode is a cooling mode, if the judgment result is that the temperature difference is less than the lower limit of a preset temperature range, the control is operated in a multi-path control mode; wherein the multi-path control mode is used to characterize a mode in which the refrigerant uses at least two circulation paths to adjust the air temperature and humidity.

[0011] It should be noted that when the air-conditioning operation mode is cooling mode, when the temperature difference is less than the lower limit of the preset temperature range, a multi-channel control mode is adopted. In this mode, the refrigerant has at least two circulation paths to ensure that the air-conditioning system can independently adjust the temperature and humidity of different areas, ensuring that each area of ​​the room can reach a comfortable temperature, avoiding the energy waste caused by unified cooling of the entire space in the single-channel control mode, and can better cope with the complex and changeable indoor environment.

[0012] According to the present invention, an intelligent air-conditioning control method is provided, which selects a corresponding control mode based on a judgment result and an air-conditioning operation mode, and controls the operation according to the selected control mode, and also includes: when the air-conditioning operation mode is a heating mode, if the judgment result is that the temperature difference meets the preset temperature range, the control operates in a multi-path control mode, and when the temperature difference meets the second energy-saving level, the control operates in a single-path shunt control mode; wherein, the multi-path control mode is used to characterize a mode in which the refrigerant uses at least two circulation paths to adjust the air temperature and humidity, and the single-path shunt control mode is used to characterize a mode in which the air conditioner distributes the refrigerant to a single path of at least two indoor units through a single main channel, and the second energy-saving level is determined in advance based on the divided temperature difference range.

[0013] It should be noted that in the heating mode, when the temperature difference meets the preset temperature range, the multi-channel control mode is adopted to distribute heat according to the actual heat demand of different areas, avoid energy waste caused by unified heating of the entire space, and achieve precise adjustment of the temperature of different areas. When the temperature difference meets the second energy-saving level, the single-channel shunt control mode is adopted to distribute the refrigerant to a single path of at least two indoor units through a single main channel, so that when the temperature is close to the target temperature, the heating situation of each indoor unit can be adjusted more finely, ensuring that the distribution of refrigerant is optimized while meeting precise temperature regulation.

[0014] According to the present invention, an intelligent air conditioning control method is provided, which selects a corresponding control mode based on a judgment result and an air conditioning operation mode, and controls the operation according to the selected control mode, and also includes: when the air conditioning operation mode is a heating mode, if the judgment result is that the temperature difference is greater than the upper limit value of a preset temperature range, the control is operated in a multi-path control mode; wherein the multi-path control mode is used to characterize a mode in which the refrigerant uses at least two circulation paths to adjust the air temperature and humidity.

[0015] It should be noted that when the temperature difference is greater than the upper limit of the preset temperature range, a multi-channel control mode is used to reasonably distribute heat according to the characteristics of different indoor areas and the distribution of heat load, and use multiple circulation paths to heat simultaneously, quickly increase the indoor temperature, so that the temperature of the entire space can be raised to a comfortable range in a short time, effectively shortening the time users wait for the indoor temperature to rise. In addition, the multi-channel control mode can be referred to above, and will not be repeated here.

[0016] According to the present invention, an intelligent air conditioning control method is provided, which selects a corresponding control mode based on a judgment result and an air conditioning operation mode, and controls the operation according to the selected control mode, and also includes: when the air conditioning operation mode is a heating mode, if the judgment result is that the temperature difference is less than the lower limit of a preset temperature range, the control is operated in a single-path control mode; wherein the single-path control mode is used to characterize a mode in which the refrigerant uses one circulation path to adjust the air temperature and humidity.

[0017] It should be noted that when the temperature difference is less than the lower limit of the preset temperature range, when the indoor temperature is already close to the target temperature, a single-path control mode is adopted to avoid instability caused by mutual interference between multiple circulation paths, thereby ensuring stable heat output and avoiding excessive temperature rise, so that the indoor temperature can be accurately maintained within the comfort range expected by the user.

[0018] According to an intelligent air-conditioning control method provided by the present invention, when the control operates according to a selected control mode, the method also includes: detecting whether the temperature difference between indoor and outdoor environments is greater than a first preset temperature; if the temperature difference is greater than the first preset temperature, the energy-saving mode is not turned on; wherein the first preset temperature is less than the lower limit of the preset temperature range; otherwise, determining the energy-saving level and weight corresponding to the temperature difference; wherein the energy-saving level is first determined based on the divided temperature difference range, and the weight is obtained by predicting the indoor and outdoor temperatures corresponding to the temperature difference and the air-conditioning operation frequency at the time corresponding to the temperature difference; detecting whether the duration of the temperature difference at the corresponding energy-saving level reaches the target duration; if the duration reaches the target duration, the air-conditioning operation capacity is increased according to the weight, and the air-conditioning operation is controlled; otherwise, the air-conditioning operation capacity is reduced according to the weight, and the air-conditioning operation is controlled.

[0019] It should be noted that whether to turn on the energy-saving mode is determined by detecting whether the temperature difference between the indoor and outdoor environments is greater than the first preset temperature. When the temperature difference is large, the energy-saving mode is not turned on to ensure that the air conditioner provides users with sufficient cooling or heating capacity in extreme environments (such as when the outdoor temperature is extremely high on a hot summer day or when the outdoor temperature is extremely low on a cold winter day) to ensure indoor comfort. For cases where the temperature difference is not greater than the first preset temperature, the energy-saving level corresponding to the temperature difference is further determined to make the activation of the energy-saving mode more detailed and accurate. The energy-saving mode is graded according to the actual temperature difference range, rather than simply turning the energy-saving mode on or off, thereby improving the applicability and effectiveness of the energy-saving mode.

[0020] The present invention also provides an intelligent air-conditioning control device, comprising: a temperature difference detection module, which receives air-conditioning control instructions and detects the temperature difference between indoor and outdoor ambient temperatures; a temperature judgment module, which determines the air-conditioning operation mode, and based on the air-conditioning operation mode, determines whether the temperature difference meets the corresponding preset temperature range to obtain a judgment result; an operation control module, which selects a corresponding control mode based on the judgment result and the air-conditioning operation mode, and controls the operation according to the selected control mode; wherein the control mode is set in advance based on the positional relationship of the temperature difference relative to the preset temperature range under different air-conditioning operation modes, and the air-conditioning operation mode is used to characterize the air-conditioning cooling or heating mode.

[0021] It should be noted that the air-conditioning control instructions are received through the temperature difference detection module, and the temperature difference between the indoor and outdoor ambient temperatures is detected. The temperature judgment module is used to select the control mode according to the air-conditioning cooling or heating mode, so that the operation control module considers the relationship between the temperature difference and the corresponding preset temperature range, so that the air-conditioning operation is more in line with actual needs, improves energy utilization efficiency as a whole, reduces energy consumption costs, and realizes precise adjustment of indoor temperature, ensuring that the indoor temperature is always kept within a comfortable range, meeting the user's precise temperature requirements in different environments.

[0022] The present invention also provides an electronic device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the steps of any of the above-mentioned air conditioning intelligent control methods are implemented.

[0023] The present invention also provides a non-transitory computer-readable storage medium on which a computer program is stored. When the computer program is executed by a processor, the steps of any of the above-mentioned air conditioning intelligent control methods are implemented. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Figure 1A flow chart of an air conditioner intelligent control method of the present invention is described, the method comprising: S11, receiving air conditioning control instructions and detecting the temperature difference between indoor and outdoor ambient temperatures; S12, determining an air conditioning operation mode, and based on the air conditioning operation mode, determining whether the temperature difference meets a corresponding preset temperature range, and obtaining a judgment result; S13, based on the judgment result and the air-conditioning operation mode, select the corresponding control mode, and control the operation according to the selected control mode; wherein the control mode is set in advance based on the position relationship of the temperature difference relative to the preset temperature range under different air-conditioning operation modes, and the air-conditioning operation mode is used to characterize the air-conditioning cooling or heating mode.

[0028] It should be noted that the step numbers "S1N" in this manual do not represent the order of the air conditioner intelligent control method. Figure 2 The air conditioner intelligent control method of the present invention is described.

[0029] Step S11, receiving an air conditioning control instruction and detecting the temperature difference between the indoor and outdoor ambient temperatures.

[0030] It should be noted that the air conditioning control command is generated based on the user's demand for controlling the air conditioning, and is used to control the air conditioning to operate according to the user's control demand. Generally, the air conditioning control command includes a power-on command and a temperature setting command, which are not further limited here. Step S12, determining the air conditioning operation mode, and based on the air conditioning operation mode, determining whether the temperature difference meets the corresponding preset temperature range to obtain a judgment result.

[0031] It is worth noting that the air-conditioning operation mode includes cooling mode and heating mode. The preset temperature range can be set according to the cooling mode and heating mode respectively, so that after determining the air-conditioning operation mode, the preset temperature range of the corresponding operation mode can be selected for comparison with the temperature difference, or the same preset temperature range can be set regardless of the cooling mode or heating mode. It can be set according to actual design requirements and is not further limited here. In addition, the preset temperature range can be set according to the actual artificial intelligence ecology (AI-ECO) and energy-saving requirements. For example, the preset temperature range can be 5-10°C, which is not further limited here.

[0032] Step S13, based on the judgment result and the air-conditioning operation mode, select the corresponding control mode, and control the operation according to the selected control mode; wherein the control mode is set based on the position relationship of the temperature difference relative to the preset temperature range under different air-conditioning operation modes, and the air-conditioning operation mode is used to characterize the air-conditioning cooling or heating mode.

[0033] In this embodiment, reference Figure 2 , based on the judgment result and the air-conditioning operation mode, the corresponding control mode is selected, and the control is operated according to the selected control mode, including: when the air-conditioning operation mode is the cooling mode, if the judgment result is that the temperature difference meets the preset temperature range or the temperature difference is greater than the upper limit of the preset temperature range, the control is operated according to the single-path control mode, and when the temperature difference meets the second energy-saving level, the control is operated according to the multi-path shunt control mode; wherein, the single-path control mode is used to characterize a mode in which the refrigerant uses one circulation path to adjust the air temperature and humidity, and the multi-path shunt control mode is used to characterize a mode in which the air conditioner distributes the refrigerant to a single path of at least two indoor units through at least two main channels, and the second energy-saving level is determined in advance based on the divided temperature difference range.

[0034] It should be noted that in cooling mode, the control mode is selected according to the relationship between the temperature difference and the preset temperature range, so that the air conditioner can flexibly adjust the operation mode according to the actual temperature changes, ensuring the best cooling effect under various temperature conditions and improving the user's comfort. In addition, when the temperature difference meets the preset temperature range or is greater than the upper limit, for scenarios where the temperature difference is not large or the temperature difference is large and requires rapid cooling, the single-channel control mode is used for rapid cooling, which can reduce unnecessary system complexity and extend the life of the equipment. When the temperature difference meets the second energy-saving level, it switches to the multi-channel shunt control mode to achieve fine control of the evaporators in different areas, further improve the accuracy of temperature regulation, and meet the cooling needs in complex scenarios such as uneven indoor temperature distribution.

[0035] It should be added that the single-circuit control mode usually refers to the air conditioning system regulating the temperature and humidity of the air through only one circulation path during its operation. Specifically, when the air conditioner is turned on and set to cooling mode, the compressor starts working and compresses the refrigerant into a high-temperature and high-pressure gas; the high-temperature and high-pressure refrigerant gas flows through the condenser of the outdoor unit, dissipates heat and condenses into a liquid; the liquid refrigerant passes through a throttling device (such as a capillary tube or an electronic expansion valve), the pressure is reduced, and the temperature also decreases; the low-temperature and low-pressure refrigerant flows through the evaporator of the indoor unit, absorbs the heat in the room, and cools the indoor air; the refrigerant is sucked into the compressor again, repeating the above cycle. When the air conditioner is turned on and set to heating mode, the air conditioning system will run in reverse, that is, the refrigerant flows in the opposite direction; the refrigerant absorbs the heat of the outside air in the evaporator of the outdoor unit (at this time as a heat absorber); the refrigerant after absorbing the heat flows through the condenser of the indoor unit (at this time as a heat emitter) and releases heat to the room.

[0036] In addition, the multi-way flow control mode means that the air conditioning system can provide independent refrigerant circulation for at least two indoor units at the same time, each area can be controlled independently, and the refrigerant output by the compressor is distributed to multiple branch pipes of each indoor unit through multiple independent flow dividers. Each branch pipe can be controlled independently, and each indoor unit can completely independently control the temperature and humidity of its area without interfering with each other. In addition, the second energy saving level can be found below, and will not be repeated here.

[0037] In an optional embodiment, based on the judgment result and the air-conditioning operation mode, a corresponding control mode is selected, and the control is operated according to the selected control mode, and also includes: when the air-conditioning operation mode is a cooling mode, if the judgment result is that the temperature difference is less than the lower limit of the preset temperature range, the control is operated according to a multi-path control mode; wherein the multi-path control mode is used to characterize a mode in which the refrigerant uses at least two circulation paths to adjust the air temperature and humidity.

[0038] It should be noted that when the air-conditioning operation mode is cooling mode, when the temperature difference is less than the lower limit of the preset temperature range, a multi-channel control mode is adopted. In this mode, the refrigerant has at least two circulation paths to ensure that the air-conditioning system can independently adjust the temperature and humidity of different areas, ensuring that each area of ​​the room can reach a comfortable temperature, avoiding the energy waste caused by unified cooling of the entire space in the single-channel control mode, and can better cope with the complex and changeable indoor environment.

[0039] It should be added that the multi-circuit control mode usually refers to the air conditioner's refrigerant circulation system having two or more independent circuits, and each circuit can circulate the refrigerant independently and can be controlled according to different needs and operating conditions. Specifically, the compressor compresses the refrigerant into a high-temperature and high-pressure gas, which becomes liquid after dissipating heat through the condenser, and then throttles and reduces the pressure through the expansion valve, becoming a low-temperature and low-pressure refrigerant, and finally flows into the indoor unit for evaporation and heat absorption; the system controls the refrigerant flow to different indoor units through multiple solenoid valves and expansion valves. Furthermore, the refrigerant flow can be adjusted according to factors such as indoor temperature distribution and load conditions.

[0040] In an optional embodiment, based on the judgment result and the air-conditioning operation mode, a corresponding control mode is selected, and the control is operated according to the selected control mode, and also includes: when the air-conditioning operation mode is a heating mode, if the judgment result is that the temperature difference meets the preset temperature range, the control is operated according to the multi-way control mode, and when the temperature difference meets the second energy-saving level, the control is operated according to the single-way shunt control mode; wherein, the multi-way control mode is used to characterize a mode in which the refrigerant uses at least two circulation paths to adjust the air temperature and humidity, and the single-way shunt control mode is used to characterize a mode in which the air conditioner distributes the refrigerant to a single path of at least two indoor units through a single main channel, and the second energy-saving level is determined in advance based on the divided temperature difference range.

[0041] It should be noted that in the heating mode, when the temperature difference meets the preset temperature range, the multi-channel control mode is adopted to distribute heat according to the actual heat demand of different areas, avoid energy waste caused by unified heating of the entire space, and achieve precise adjustment of the temperature of different areas. When the temperature difference meets the second energy-saving level, the single-channel shunt control mode is adopted to distribute the refrigerant to a single path of at least two indoor units through a single main channel, so that when the temperature is close to the target temperature, the heating situation of each indoor unit can be adjusted more finely, ensuring that the distribution of refrigerant is optimized while meeting precise temperature regulation.

[0042] It should be added that the single-circuit shunt control mode means that after the refrigerant of the air-conditioning system comes out of the compressor, it is distributed to a single path of each indoor unit through a main valve. In this mode, after the refrigerant comes out of the compressor, it is distributed to a single branch pipe of each indoor unit through a main shunt. Each indoor unit can independently control the temperature of its area, but all indoor units share the same refrigerant cycle. In addition, the multi-circuit control mode can be referred to above, and will not be repeated here.

[0043] In an optional embodiment, based on the judgment result and the air-conditioning operation mode, a corresponding control mode is selected, and the control is operated according to the selected control mode, and also includes: when the air-conditioning operation mode is a heating mode, if the judgment result is that the temperature difference is greater than the upper limit value of the preset temperature range, the control is operated according to a multi-path control mode; wherein the multi-path control mode is used to characterize a mode in which the refrigerant uses at least two circulation paths to adjust the air temperature and humidity.

[0044] It should be noted that when the temperature difference is greater than the upper limit of the preset temperature range, a multi-channel control mode is used to reasonably distribute heat according to the characteristics of different indoor areas and the distribution of heat load, and use multiple circulation paths to heat simultaneously, quickly increase the indoor temperature, so that the temperature of the entire space can be raised to a comfortable range in a short time, effectively shortening the time users wait for the indoor temperature to rise. In addition, the multi-channel control mode can be referred to above, and will not be repeated here.

[0045] In an optional embodiment, based on the judgment result and the air-conditioning operation mode, a corresponding control mode is selected, and the control is operated according to the selected control mode, and also includes: when the air-conditioning operation mode is a heating mode, if the judgment result is that the temperature difference is less than the lower limit of the preset temperature range, the control is operated according to a single-circuit control mode; wherein the single-circuit control mode is used to characterize a mode in which the refrigerant uses a circulation path to adjust the air temperature and humidity.

[0046] It should be noted that when the temperature difference is less than the lower limit of the preset temperature range, when the indoor temperature is already close to the target temperature, a single-path control mode is adopted to avoid instability caused by mutual interference between multiple circulation paths, thereby ensuring stable heat output and avoiding excessive temperature rise, so that the indoor temperature can be accurately maintained within the comfort range expected by the user.

[0047] In an optional embodiment, when the control operates according to the selected control mode, the method also includes: detecting whether the temperature difference between the indoor and outdoor environments is greater than a first preset temperature; if the temperature difference is greater than the first preset temperature, the energy-saving mode is not turned on; wherein the first preset temperature is less than the lower limit of the preset temperature range; otherwise, determining the energy-saving level and weight corresponding to the temperature difference; wherein the energy-saving level is determined in advance based on the divided temperature difference range, and the weight is obtained based on the indoor and outdoor temperatures corresponding to the temperature difference and the air-conditioning operation frequency at the time corresponding to the temperature difference; detecting whether the duration of the temperature difference at the corresponding energy-saving level reaches the target duration; if the duration reaches the target duration, the air-conditioning operation capacity is increased according to the weight, and the air-conditioning operation is controlled; otherwise, the air-conditioning operation capacity is reduced according to the weight, and the air-conditioning operation is controlled.

[0048] It should be noted that by detecting whether the temperature difference between the indoor and outdoor environments is greater than the first preset temperature, it is determined whether to turn on the energy-saving mode. When the temperature difference is large, the energy-saving mode is not turned on to ensure that the air conditioner provides users with sufficient cooling or heating capacity in extreme environments (such as when the outdoor temperature is extremely high in hot summer or extremely low in cold winter) to ensure indoor comfort. For the case where the temperature difference is not greater than the first preset temperature, the energy-saving level corresponding to the temperature difference is further determined to make the activation of the energy-saving mode more detailed and accurate. The energy-saving mode is graded according to the actual temperature difference range, rather than simply turning the energy-saving mode on or off, thereby improving the applicability and effectiveness of the energy-saving mode. In addition, the target duration can be set according to the actual energy-saving design requirements, such as 30 minutes, 45 minutes, etc., which is not further limited here.

[0049] Specifically, the energy saving level includes a first energy saving level, a second energy saving level and a third energy saving level. The first energy saving level corresponds to a first temperature difference range, the second energy saving level corresponds to a second temperature difference range, and the third energy saving level corresponds to a third temperature difference range. The upper limit value of the first temperature difference range is equal to the first preset temperature, the lower limit value of the first temperature difference range is equal to the upper limit value of the second temperature difference range, the lower limit value of the second temperature difference range is equal to the upper limit value of the third temperature difference range, and the lower limit value of the third temperature difference range is greater than or equal to the first preset value.

[0050] It should be noted that when the energy-saving level only includes three levels, the first preset value is greater than or equal to 0, and when the energy-saving level is more than three levels, the first preset value is greater than 0. For example, if the energy-saving level is divided into three levels, the temperature difference range of the first energy-saving level is (2,3], the temperature difference range of the second energy-saving level is (1,2], and the temperature difference range of the third energy-saving level is [0,1]. The specific energy-saving level and temperature difference range can be set according to the actual energy-saving needs, and no further limitation is made here.

[0051] In addition, in the initial state, the first energy-saving level, the second energy-saving level and the third energy-saving level need to set initial weights, which can be set according to actual operating requirements and energy-saving requirements. For example, the initial weight of the first energy-saving level is 80%, the initial weight of the second energy-saving level is 60%, and the initial weight of the third energy-saving level is 40%. Alternatively, the initial weight of the first energy-saving level is 90%, the initial weight of the second energy-saving level is 70%, and the initial weight of the third energy-saving level is 50%. No further limitation is made here.

[0052] Further, determining the energy saving level corresponding to the temperature difference includes: determining the range to which the temperature difference belongs according to the first temperature difference range, the second temperature difference range and the third temperature difference range, and obtaining the corresponding energy saving level.

[0053] In addition, determining the weight corresponding to the temperature difference includes: obtaining the indoor and outdoor temperatures corresponding to the temperature difference and the air conditioning operation frequency at the time corresponding to the temperature difference; inputting the indoor and outdoor temperatures and the air conditioning operation frequency into the weight prediction model to obtain the weight output by the weight prediction model; wherein the weight prediction model is trained based on the temperature training data and the frequency operation data and weight labels corresponding to the temperature training data.

[0054] To summarize, the embodiments of the present invention receive air-conditioning control instructions, detect the temperature difference between indoor and outdoor ambient temperatures, and select a control mode based on the air-conditioning cooling or heating mode, taking into account the relationship between the temperature difference and the corresponding preset temperature range, so that the air-conditioning operation is more in line with actual needs, and the overall energy utilization efficiency is improved, the energy consumption cost is reduced, and the indoor temperature is accurately adjusted to ensure that the indoor temperature is always kept within a comfortable range, meeting the user's precise temperature requirements in different environments.
