[0037] Figure 1 is a schematic diagram of a method for controlling an electronic expansion valve provided by an embodiment of the present disclosure; in combination with Figure 1 As shown, an embodiment of the present disclosure provides a method for controlling an electronic expansion valve, including:
[0038] S11, the air conditioner determines the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner.
[0039] S12, the air conditioner determines an opening adjustment strategy for the electronic expansion valve according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner.
[0040] S13, the air conditioner controls the air conditioner to execute the opening adjustment strategy of the electronic expansion valve.
[0041] In this solution, the air conditioner includes an indoor unit and an outdoor unit. Among them, the indoor unit of the air conditioner is responsible for blowing the temperature-regulated air into the room to achieve the purpose of regulating the indoor temperature. The indoor unit of the air conditioner is usually installed on the indoor wall, ceiling or cabinet, and specifically includes components such as a fan, an evaporator for cooling or a heating element for heating. Similarly, the outdoor unit of the air conditioner mainly undertakes the function of heat exchange, dissipating the indoor heat to the outside during cooling, and absorbing heat from the outside to supply the indoor during heating. The outdoor unit of the air conditioner is usually installed on the outside of the building, and includes key components such as a compressor, a condenser for heat dissipation in the refrigeration cycle, or an evaporator for absorbing heat from the outside.
[0042] Optionally, the energy conversion value of the air conditioner is a quantitative indicator used to measure the efficiency or ability of the air conditioner to convert energy to achieve the required temperature set by the user, which reflects the amount of energy consumed and converted by the air conditioner in the process of adjusting the indoor temperature from the current value to the user's required value. The energy conversion value of the air conditioner can be based on the speed of the indoor fan, the difference between the current indoor temperature and the required temperature set by the user, and the fixed coefficient k 1 For example, J 1 =k 1 ×S 1 ×丨T 2 -T 1 丨. Among them, J 1 is the energy conversion value of the air conditioner indoor unit, k 1 is the first coefficient, S 1 is the indoor fan speed of the air conditioner, T 2 -T 1 The difference between the required temperature set by the user and the indoor temperature of the air conditioner. With this solution, the fan speed, current temperature difference and fixed coefficient k can be used to calculate the indoor temperature of the air conditioner. 1 Accurately quantify the energy efficiency consumed and converted by the indoor unit when adjusting the indoor temperature to the set value.
[0043] Optionally, the air conditioner outdoor unit energy conversion value is a quantitative indicator used to measure the efficiency or ability of the air conditioner outdoor unit to convert energy during the heat exchange process. It reflects the amount of energy consumed and converted by the air conditioner outdoor unit in the process of emitting heat or absorbing heat to maintain a stable indoor temperature. The air conditioner outdoor unit energy conversion value can be based on the speed of the outdoor fan, the difference between the outdoor temperature and the coil temperature, and the fixed coefficient k 2 For example, J 2 =k 2 ×S 2 ×丨T 3 -T丨. Among them, J 2 is the energy conversion value of the air conditioner outdoor unit, k 2 is the second coefficient, S 2is the rotational speed of the outdoor fan of the air conditioner, T 3 -T is the difference between the coil temperature of the air conditioner and the outdoor temperature where the air conditioner is located. With this solution, it is possible to accurately quantify the energy efficiency consumed and converted by the outdoor unit during heat exchange based on the fan speed, outdoor temperature difference, and fixed coefficient k 2 Precisely quantify the energy efficiency consumed and converted by the outdoor unit during heat exchange.
[0044] Furthermore, after the air conditioner calculates the energy conversion value of the indoor unit and the energy conversion value of the outdoor unit of the air conditioner, it can combine the energy conversion value of the indoor unit and the energy conversion value of the outdoor unit of the air conditioner to determine the opening adjustment strategy of the electronic expansion valve. Specifically, the air conditioner determines the opening adjustment strategy of the electronic expansion valve according to the energy conversion value of the indoor unit and the energy conversion value of the outdoor unit of the air conditioner, including: The air conditioner determines the opening change amount of the electronic expansion valve according to the energy conversion value of the indoor unit and the energy conversion value of the outdoor unit of the air conditioner. The air conditioner determines the target opening of the electronic expansion valve according to the opening change amount of the electronic expansion valve and the current opening of the electronic expansion valve. The air conditioner determines that the opening adjustment strategy of the electronic expansion valve is to adjust the electronic expansion valve according to the target opening. With this solution, it is possible to determine the opening change amount of the electronic expansion valve based on the energy conversion values of the indoor unit and the outdoor unit of the air conditioner, and calculate the target opening in combination with its current opening. This adjustment strategy provides an accurate data basis for the adjustment of the electronic expansion valve. In this way, after determining the opening adjustment strategy of the electronic expansion valve, the air conditioner can control the air conditioner to execute the opening adjustment strategy of the electronic expansion valve.
[0045] By using the method for controlling the electronic expansion valve provided in the embodiments of the present disclosure, by accurately calculating the energy conversion values of the indoor and outdoor units of the air conditioner in real time and dynamically adjusting the opening of the electronic expansion valve accordingly, the problem of unbalanced energy output between the indoor and outdoor units caused by ignoring the dynamic relationship between the opening of the electronic expansion valve and the energy conversion of the indoor and outdoor units of the air conditioner is effectively solved. With this solution, the balanced optimization of the energy output between the indoor and outdoor units is achieved, significantly improving the overall energy efficiency and stability of the air conditioning system, and providing users with a more efficient, environmentally friendly and stable air conditioning use experience.
[0046] Figure 2 is a schematic diagram of a method for determining an opening adjustment strategy provided by an embodiment of the present disclosure; combined with Figure 2 As shown, optionally, S12, the air conditioner determines the opening adjustment strategy of the electronic expansion valve according to the energy conversion value of the indoor unit and the energy conversion value of the outdoor unit of the air conditioner, including:
[0047] S21, the air conditioner determines the opening change amount of the electronic expansion valve according to the energy conversion value of the indoor unit and the energy conversion value of the outdoor unit of the air conditioner.
[0048] S22, the air conditioner determines the target opening of the electronic expansion valve according to the opening change amount of the electronic expansion valve and the current opening of the electronic expansion valve.
[0049] S23. The air conditioner determines that the opening adjustment strategy of the electronic expansion valve is to adjust the electronic expansion valve according to the target opening.
[0050] In this solution, the air conditioner can determine the opening change amount of the electronic expansion valve according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, including: when the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, according to △θ = θ×(J 1 -J 2 ) / J 2 calculate the opening change amount of the electronic expansion valve; when the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, according to △θ = θ×(J 2 -J 1 ) / J 2 calculate the opening change amount of the electronic expansion valve; where, △θ is the opening change amount of the electronic expansion valve, J 1 is the energy conversion value of the indoor unit of the air conditioner, J 2 is the energy conversion value of the outdoor unit of the air conditioner, and θ is the current opening of the electronic expansion valve. In another way, in order to avoid the adverse impact on the operation of the air conditioner caused by the instantaneous excessive adjustment of the opening of the electronic expansion valve, the user can also pre-store the opening change amount of the electronic expansion valve in the air conditioner in advance. With this solution, the air conditioner can dynamically calculate the opening change amount through an intelligent algorithm based on the energy conversion value difference between the indoor unit and the outdoor unit; at the same time, the user can also preset the opening change amount in advance to avoid the adverse impact caused by the instantaneous large adjustment, so as to achieve the refined control of the opening of the electronic expansion valve while ensuring the stable operation of the air conditioner.
[0051] Optionally, the air conditioner can determine the target opening of the electronic expansion valve according to the opening change amount of the electronic expansion valve and the current opening of the electronic expansion valve, including: when the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, according to △θ = θ×(J 1 -J 2 ) / J 2 calculate the opening change amount of the electronic expansion valve; when the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, according to △θ = θ×(J 2 -J 1 ) / J 2 calculate the opening change amount of the electronic expansion valve; where, △θ is the opening change amount of the electronic expansion valve, J 1 is the energy conversion value of the indoor unit of the air conditioner, J 2Let \(J\) be the energy conversion value of the outdoor unit of the air conditioner, and \(\theta\) be the current opening degree of the electronic expansion valve. In this way, after determining the change amount of the opening degree of the electronic expansion valve, the air conditioner can determine the opening degree adjustment strategy of the electronic expansion valve as adjusting the electronic expansion valve according to the target opening degree. With this solution, by comprehensively considering the energy conversion values of the indoor and outdoor units of the air conditioner, accurately calculating the change amount of the opening degree of the electronic expansion valve, and determining the target opening degree accordingly, the accurate determination of the opening degree adjustment strategy of the electronic expansion valve is achieved, significantly improving the operating efficiency and stability of the air conditioner system.
[0052] Optionally, in S21, the air conditioner determines the change amount of the opening degree of the electronic expansion valve according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, including:
[0053] When the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner calculates the change amount of the opening degree of the electronic expansion valve according to \(\Delta\theta=\theta\times(J 1 -J 2 ) / J 2 .
[0054] When the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner calculates the change amount of the opening degree of the electronic expansion valve according to \(\Delta\theta=\theta\times(J 2 -J 1 ) / J 2 .
[0055] Wherein, \(\Delta\theta\) is the change amount of the opening degree of the electronic expansion valve, \(J 1 is the energy conversion value of the indoor unit of the air conditioner, \(J 2 is the energy conversion value of the outdoor unit of the air conditioner, and \(\theta\) is the current opening degree of the electronic expansion valve.
[0056] With this solution, the accurate change amount of the opening degree of the electronic expansion valve can be calculated based on a specific algorithm, ensuring the accuracy of the opening degree adjustment of the electronic expansion valve and the effectiveness of energy efficiency optimization.
[0057] Optionally, in S22, the air conditioner determines the target opening degree of the electronic expansion valve according to the change amount of the opening degree of the electronic expansion valve and the current opening degree of the electronic expansion valve, including:
[0058] When the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner takes the sum of the current opening degree of the electronic expansion valve and the change amount of the opening degree of the electronic expansion valve as the target opening degree of the electronic expansion valve.
[0059] When the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner takes the difference between the current opening degree of the electronic expansion valve and the change amount of the opening degree of the electronic expansion valve as the target opening degree of the electronic expansion valve.
[0060] In this solution, when the energy conversion value of the indoor unit of the air conditioner is greater than that of the outdoor unit, the air conditioner takes the sum of the current opening degree of the electronic expansion valve and the opening degree change of the electronic expansion valve as the target opening degree of the electronic expansion valve. That is, θ 目标 = θ + △θ. When the energy conversion value of the indoor unit of the air conditioner is less than that of the outdoor unit, the air conditioner takes the difference between the current opening degree of the electronic expansion valve and the opening degree change of the electronic expansion valve as the target opening degree of the electronic expansion valve. That is, θ 目标 = θ - △θ. With this solution, by comprehensively considering the current opening degree of the electronic expansion valve and the opening degree change of the electronic expansion valve, the target opening degree of the electronic expansion valve is accurately calculated.
[0061] Figure 3 FIG. is a schematic diagram of a method for calculating the energy conversion value of the indoor unit of an air conditioner provided by an embodiment of the present disclosure; in combination with Figure 3 as shown, optionally, S11, the air conditioner determines the energy conversion value of the indoor unit of the air conditioner, including:
[0062] S31, the air conditioner obtains the required temperature set by the user, the indoor temperature where the air conditioner is located, the indoor fan speed of the air conditioner, and the first coefficient.
[0063] S32, the air conditioner calculates the difference between the required temperature set by the user and the indoor temperature where the air conditioner is located.
[0064] S33, the air conditioner calculates the energy conversion value of the indoor unit of the air conditioner according to the difference between the required temperature set by the user and the indoor temperature where the air conditioner is located, the indoor fan speed of the air conditioner, and the first coefficient.
[0065] In this solution, the air conditioner can receive the instruction input by the user through its control panel or the application program of the associated mobile device to extract the required temperature set by the user. The air conditioner can collect the indoor temperature where the air conditioner is located and the indoor fan speed of the air conditioner through its associated indoor sensing device. With this solution, the required temperature set by the user, the indoor temperature where the air conditioner is located, and the indoor fan speed of the air conditioner can be accurately obtained.
[0066] In this solution, the first coefficient can be determined in the following way:
[0067] The air conditioner obtains the fan speed of the indoor unit and the corresponding indoor unit operating power at different times.
[0068] The air conditioner calculates the ratio of the indoor unit operating power to the fan speed at the same time as the instantaneous proportionality constant at that time.
[0069] The air conditioner takes the average value of the instantaneous proportionality constants obtained at multiple times as the first coefficient.
[0070] For example, the ratio of the operating power of the indoor unit to the fan speed calculated by the air conditioner at the same time includes: 50.6 / 800=0.063, 54.8 / 900=0.061, 85.8 / 1400=0.061 and 100.2 / 1600=0.063, then the first coefficient can be determined as (0.063+0.061+0.061+0.063) / 4=0.62. In this scheme, by accurately measuring and calculating the ratio of the operating power of the indoor unit of the air conditioner to the fan speed at different times, and taking the average value of these instantaneous proportional constants, the first coefficient can be accurately and reliably determined.
[0071] Furthermore, the air conditioner can calculate the difference between the required temperature set by the user and the indoor temperature where the air conditioner is located. And based on the difference between the required temperature set by the user and the indoor temperature where the air conditioner is located, the indoor fan speed of the air conditioner and the first coefficient, the energy conversion value of the air conditioner indoor unit is calculated. Specifically, the air conditioner calculates the energy conversion value of the air conditioner indoor unit according to the difference between the required temperature set by the user and the indoor temperature where the air conditioner is located, the indoor fan speed of the air conditioner and the first coefficient, including:
[0072] J 1 =k 1 ×S 1 ×丨T 2 -T 1 丨
[0073] Among them, J 1 is the energy conversion value of the air conditioner indoor unit, k 1 is the first coefficient, S 1 is the indoor fan speed of the air conditioner, T 2 -T 1 The difference between the required temperature set by the user and the indoor temperature where the air conditioner is located. This solution not only takes into account the user's direct demand for temperature adjustment, but also takes into account the real-time operating status of the air conditioner's indoor fan, and based on these parameters, the energy conversion value of the air conditioner indoor unit is accurately determined.
[0074] Figure 4 is a schematic diagram of a method for calculating the energy conversion value of an air conditioner outdoor unit provided by an embodiment of the present disclosure; Figure 4 As shown, optionally, in S11, the air conditioner determines the energy conversion value of the air conditioner outdoor unit, including:
[0075] S41, the air conditioner obtains the coil temperature of the air conditioner, the outdoor temperature where the air conditioner is located, the outdoor fan speed of the air conditioner, and the second coefficient.
[0076] S42, the air conditioner calculates the difference between the coil temperature of the air conditioner and the outdoor temperature where the air conditioner is located.
[0077] S43, the air conditioner calculates the energy conversion value of the air conditioner outdoor unit according to the difference between the coil temperature of the air conditioner and the outdoor temperature where the air conditioner is located, the outdoor fan speed of the air conditioner and the second coefficient.
[0078] In this solution, the air conditioner can directly measure the coil temperature by installing a temperature sensor on the air conditioner coil. The air conditioner can collect the outdoor temperature where the air conditioner is located and the outdoor fan speed of the air conditioner through its associated outdoor sensor device. With this solution, the coil temperature of the air conditioner, the outdoor temperature where the air conditioner is located, and the outdoor fan speed of the air conditioner can be accurately obtained.
[0079] In this solution, the second coefficient can be determined by:
[0080] The air conditioner obtains the fan speed of the outdoor unit and the corresponding operating power of the outdoor unit at different times.
[0081] The air conditioner calculates the ratio of the outdoor unit operating power to the fan speed at the same moment as the instantaneous proportional constant at that moment.
[0082] The air conditioner takes an average value of the instantaneous proportional constants obtained at multiple moments as the second coefficient.
[0083] In the actual test process, the ratio of the operating power of the air conditioner outdoor unit to the fan speed at the same time includes: 81.29 / 1217=0.066, 77.78 / 1193=0.065, 75.31 / 1156=0.065 and 72.72 / 1117=0.065, and the first coefficient can be determined as (0.066+0.065+0.065+0.065) / 4=0.65. With this scheme, by accurately measuring and calculating the ratio of the operating power of the air conditioner outdoor unit to the fan speed at different times, and taking the average value of these instantaneous proportional constants, the second coefficient can be accurately and reliably determined.
[0084] Further, the air conditioner can calculate the difference between the coil temperature of the air conditioner and the outdoor temperature where the air conditioner is located. And based on the difference between the coil temperature of the air conditioner and the outdoor temperature where the air conditioner is located, the outdoor fan speed of the air conditioner and the second coefficient, the energy conversion value of the air conditioner outdoor unit is calculated. Specifically, the air conditioner calculates the energy conversion value of the air conditioner outdoor unit according to the difference between the coil temperature of the air conditioner and the outdoor temperature where the air conditioner is located, the outdoor fan speed of the air conditioner and the second coefficient, including:
[0085] J 2 =k 2 ×S 2 ×丨T 3 -T丨
[0086] Among them, J 2 is the energy conversion value of the air conditioner outdoor unit, k 2 is the second coefficient, S 2is the rotational speed of the outdoor fan of the air conditioner, T 3 -T is the difference between the coil temperature of the air conditioner and the outdoor temperature where the air conditioner is located. With this solution, the accurate determination of the energy conversion value of the outdoor unit of the air conditioner is achieved.
[0087] Optionally, after controlling the air conditioner panel to adjust the panel opening according to the opening adjustment range, the method further includes:
[0088] The air conditioner obtains the current energy conversion value of the indoor unit of the air conditioner and the current energy conversion value of the outdoor unit of the air conditioner.
[0089] The air conditioner calculates the difference between the current energy conversion value of the indoor unit of the air conditioner and the current energy conversion value of the outdoor unit of the air conditioner.
[0090] When the difference between the current energy conversion value of the indoor unit of the air conditioner and the current energy conversion value of the outdoor unit of the air conditioner meets the set condition, the air conditioner pushes a prompt message to the user so that the user can know that the energy output of the current indoor and outdoor units of the air conditioner is balanced.
[0091] In this solution, after controlling the air conditioner compressor to operate at the target operating frequency, the air conditioner can obtain the current energy conversion value of the indoor unit of the air conditioner and the current energy conversion value of the outdoor unit of the air conditioner again, and calculate the difference between the current energy conversion value of the indoor unit of the air conditioner and the current energy conversion value of the outdoor unit of the air conditioner. Thus, when the difference between the current energy conversion value of the indoor unit of the air conditioner and the current energy conversion value of the outdoor unit of the air conditioner meets the set condition, a prompt message is pushed to the user so that the user can know that the energy output of the current indoor and outdoor units of the air conditioner is balanced. With this solution, by obtaining and calculating the difference between the energy conversion values of the indoor and outdoor units of the air conditioner, when the difference meets the preset condition, a prompt message can be intelligently pushed to the user, enabling the user to intuitively understand that the energy output of the current indoor and outdoor units of the air conditioner reaches a balanced state, thereby enhancing the transparency of the air conditioner operation and the user experience.
[0092] Optionally, the following method is used to determine that the difference between the current energy conversion value of the indoor unit of the air conditioner and the current energy conversion value of the outdoor unit of the air conditioner meets the set condition:
[0093] The air conditioner takes the product of the current energy conversion value of the outdoor unit of the air conditioner and the third coefficient as the deviation threshold.
[0094] When the difference between the current energy conversion value of the indoor unit of the air conditioner and the current energy conversion value of the outdoor unit of the air conditioner is less than the deviation threshold, the air conditioner determines that the difference between the current energy conversion value of the indoor unit of the air conditioner and the current energy conversion value of the outdoor unit of the air conditioner meets the set condition.
[0095] In this solution, the air conditioner can determine the third coefficient by obtaining the horsepower information of the air conditioner. The larger the horsepower of the air conditioner, the larger the corresponding third coefficient value. Specifically, the value range of the third coefficient is 2% to 5%. In this way, the air conditioner can use the product of the current energy conversion value of the outdoor unit of the air conditioner and the third coefficient as the deviation threshold. And when the difference between the current energy conversion value of the indoor unit of the air conditioner and the current energy conversion value of the outdoor unit of the air conditioner is less than the deviation threshold, the air conditioner determines that the difference between the current energy conversion value of the indoor unit of the air conditioner and the current energy conversion value of the outdoor unit of the air conditioner meets the set conditions. With this solution, it is possible to accurately determine whether the difference between the current energy conversion value of the indoor unit of the air conditioner and the current energy conversion value of the outdoor unit of the air conditioner meets the set conditions.
[0096] An embodiment of the present disclosure provides a method for controlling an outdoor fan of an air conditioner, including:
[0097] The air conditioner determines the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner.
[0098] The air conditioner determines an adjustment strategy for the rotational speed of the outdoor fan of the air conditioner according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner.
[0099] The air conditioner controls the air conditioner to execute the adjustment strategy for the rotational speed of the outdoor fan of the air conditioner.
[0100] In this solution, after the air conditioner calculates the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, it can determine the adjustment strategy for the rotational speed of the outdoor fan of the air conditioner in combination with the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner. Specifically, the air conditioner determines the adjustment strategy for the rotational speed of the outdoor fan of the air conditioner according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, including: when the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner determines that the adjustment strategy for the rotational speed of the outdoor fan of the air conditioner is to control the outdoor fan of the air conditioner to increase the rotational speed according to a target amplitude. When the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner determines that the adjustment strategy for the rotational speed of the outdoor fan of the air conditioner is to control the outdoor fan of the air conditioner to decrease the rotational speed according to a target amplitude. With this solution, by accurately comparing the energy conversion values of the indoor and outdoor units of the air conditioner, highly precise control of the adjustment strategy for the rotational speed of the outdoor fan of the air conditioner is achieved. When the energy conversion of the indoor unit is higher than that of the outdoor unit, the air conditioner can accurately determine and control the outdoor fan to speed up according to a preset target amplitude to match the energy demand; conversely, if the energy conversion of the indoor unit is lower than that of the outdoor unit, the air conditioner precisely regulates the outdoor fan to decelerate to avoid energy redundancy, thereby ensuring the best balance between the overall operating efficiency of the air conditioner and energy consumption control. In this way, after determining the adjustment strategy for the rotational speed of the outdoor fan of the air conditioner, the air conditioner can control the air conditioner to execute the adjustment strategy for the rotational speed of the outdoor fan of the air conditioner.
[0101] By adopting the method for controlling the outdoor fan of an air conditioner provided by the embodiments of the present disclosure, through accurately calculating the energy conversion values of the indoor and outdoor units of the air conditioner and determining the rotational speed adjustment strategy of the outdoor fan accordingly, the reasonable control of the outdoor fan is achieved. This control method can dynamically balance the energy output of the indoor and outdoor units of the air conditioner, effectively solving the problem of imbalance in the energy conversion efficiency between the indoor and outdoor units caused by neglecting the parameters of the outdoor fan. By optimizing the operating state of the outdoor fan, not only the overall energy efficiency of the air conditioner system is improved, but also the stability of the system is enhanced, further optimizing the user experience.
[0102] Optionally, the air conditioner determines the rotational speed adjustment strategy of the outdoor fan of the air conditioner according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, including:
[0103] When the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner determines that the rotational speed adjustment strategy of the outdoor fan of the air conditioner is to control the outdoor fan of the air conditioner to increase the rotational speed according to the target amplitude.
[0104] When the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner determines that the rotational speed adjustment strategy of the outdoor fan of the air conditioner is to control the outdoor fan of the air conditioner to decrease the rotational speed according to the target amplitude.
[0105] In this solution, after the air conditioner determines the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, the energy conversion value of the indoor unit of the air conditioner can be compared with the energy conversion value of the outdoor unit of the air conditioner. And when the energy conversion value of the indoor unit is higher than that of the outdoor unit, it indicates that the air conditioner is overloaded during operation, then the rotational speed of the outdoor fan can be increased to enhance the energy output; on the contrary, when the energy conversion value of the indoor unit is lower than that of the outdoor unit, it means that the air conditioner is operating redundantly, then the rotational speed of the outdoor fan can be decreased to reduce energy consumption, so as to ensure the overall energy balance and efficient operation of the air conditioner. In this way, by comparing the energy conversion value of the indoor unit of the air conditioner with that of the outdoor unit, the rotational speed of the outdoor fan is intelligently adjusted to balance the energy output.
[0106] Optionally, the target amplitude is determined by the following method:
[0107] When the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner calculates the target amplitude according to △V = S 2 ×(J 1 - J 2 ) / J 2
[0108] When the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner calculates the target amplitude according to △V = S 2 ×(J 2 - J 1 ) / J 2
[0109] where, △V is the target amplitude, and J 1 is the energy conversion value of the indoor unit of the air conditioner, in J 2 is the energy conversion value of the outdoor unit of the air conditioner, in S 2 is the rotational speed of the outdoor fan of the air conditioner.
[0110] With this solution, the accurate rotational speed adjustment amplitude can be calculated based on a specific algorithm, ensuring the accuracy of the rotational speed adjustment of the outdoor fan of the air conditioner and the effectiveness of energy efficiency optimization.
[0111] In another example, the user can also preset the target amplitude according to the actual situation. With this solution, by reasonably setting the target amplitude, it effectively prevents the excessive instantaneous change in rotational speed that may be caused by the automatic calculation of the air conditioner, thereby avoiding unnecessary mechanical stress on the fan, reducing noise interference and energy consumption fluctuations, and ensuring that the air conditioner operates efficiently while maintaining the stable operation life of the equipment and the user's comfort.
[0112] An embodiment of the present disclosure discloses a method for controlling an air conditioner compressor, including:
[0113] The air conditioner determines the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner.
[0114] The air conditioner determines the target operating frequency of the air conditioner compressor according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner.
[0115] The air conditioner controls the air conditioner compressor to operate at the target operating frequency.
[0116] Further, after the air conditioner calculates the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, it can determine the target operating frequency of the air conditioner compressor in combination with the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner. Specifically, the air conditioner determines the target operating frequency of the air conditioner compressor according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, including: The air conditioner determines the adjustment trend and adjustment amplitude of the operating frequency of the air conditioner compressor according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner. The air conditioner determines the target operating frequency of the air conditioner compressor according to the current operating frequency of the air conditioner compressor, the adjustment trend of the operating frequency of the air conditioner compressor, and the adjustment amplitude. With this solution, by accurately calculating the energy conversion values of the indoor and outdoor units of the air conditioner and determining the trend and amplitude of the adjustment of the compressor operating frequency accordingly, the accurate determination of the target operating frequency of the compressor is realized. In this way, after the air conditioner determines the target operating frequency of the air conditioner compressor, it controls the air conditioner compressor to operate at the target operating frequency.
[0117] By adopting the method for controlling an air-conditioning compressor provided by the embodiments of the present disclosure, the target operating frequency of the compressor is dynamically adjusted by determining the energy conversion value between the indoor unit and the outdoor unit of the air conditioner, so as to achieve the synchronization and balance of the energy output between the indoor and outdoor units of the air conditioner. With this solution, the target operating frequency of the compressor can be adjusted based on the actual demand for energy conversion between the indoor and outdoor units of the air conditioner, and it also avoids energy waste and overloading of equipment that may be caused by asynchronous energy conversion between the indoor and outdoor units. Furthermore, the overall energy efficiency of the air conditioner is improved, the service life of the equipment is extended, and the user experience is optimized.

[0120] The air conditioner determines the target operating frequency of the air-conditioning compressor according to the current operating frequency of the air-conditioning compressor, the adjustment trend of the operating frequency of the air-conditioning compressor, and the adjustment amplitude.
[0121] In this solution, the air conditioner determines the adjustment trend of the operating frequency of the air-conditioning compressor according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, including: when the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner determines that the adjustment trend of the air-conditioning compressor is an increasing trend. When the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner determines that the adjustment trend of the air-conditioning compressor is a decreasing trend. With this solution, by comparing the energy conversion values of the indoor and outdoor units of the air conditioner, the adjustment trend of the operating frequency of the air-conditioning compressor is intelligently determined. When the energy conversion value of the indoor unit is higher than that of the outdoor unit, it indicates that the air conditioner is overloaded, so it can be determined that the adjustment trend of the operating frequency of the air-conditioning compressor is an increasing trend to enhance the cooling / heating efficiency. On the contrary, if the energy conversion value of the indoor unit is lower than that of the outdoor unit, it indicates that there is redundancy in the operation of the air conditioner, so it can be determined that the adjustment trend of the operating frequency of the air-conditioning compressor is a decreasing trend to achieve energy conservation and optimized operation.
[0122] Further, the air conditioner can determine the target operating frequency of the air conditioner compressor by combining the current operating frequency of the air conditioner compressor, the adjustment trend of the operating frequency of the air conditioner compressor, and the adjustment amplitude. Specifically, the air conditioner determines the target operating frequency of the air conditioner compressor according to the current operating frequency of the air conditioner compressor, the adjustment trend of the operating frequency of the air conditioner compressor, and the adjustment amplitude, including: when the adjustment trend of the operating frequency of the air conditioner compressor is an increasing trend, the air conditioner takes the sum of the current operating frequency of the air conditioner compressor and the adjustment amplitude as the target operating frequency of the air conditioner compressor. When the adjustment trend of the operating frequency of the air conditioner compressor is a decreasing trend, the difference between the current operating frequency of the air conditioner compressor and the adjustment amplitude is taken as the target operating frequency of the air conditioner compressor. With this solution, by comprehensively considering the current operating frequency, adjustment trend, and adjustment amplitude of the air conditioner compressor, the target operating frequency of the compressor is accurately calculated.
[0123] Optionally, the air conditioner determines the adjustment trend of the operating frequency of the air conditioner compressor according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, including:
[0124] When the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner determines that the adjustment trend of the operating frequency of the air conditioner compressor is an increasing trend.
[0125] When the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner determines that the adjustment trend of the operating frequency of the air conditioner compressor is a decreasing trend.
[0126] In this solution, by comparing the energy conversion values of the indoor and outdoor units of the air conditioner, the adjustment trend of the operating frequency of the air conditioner compressor is intelligently determined. When the energy conversion value of the indoor unit is higher than that of the outdoor unit, it indicates that the air conditioner is overloaded during operation, and it can be determined that the adjustment trend of the operating frequency of the air conditioner compressor is an increasing trend to enhance the cooling / heating efficiency. On the contrary, if the energy conversion value of the indoor unit is lower than that of the outdoor unit, it indicates that there is redundancy in the operation of the air conditioner, and it can be determined that the adjustment trend of the operating frequency of the air conditioner compressor is a decreasing trend to achieve energy conservation and optimized operation.
[0127] Optionally, the air conditioner determines the target operating frequency of the air conditioner compressor according to the current operating frequency of the air conditioner compressor, the adjustment trend of the operating frequency of the air conditioner compressor, and the adjustment amplitude, including:
[0128] When the adjustment trend of the operating frequency of the air conditioner compressor is an increasing trend, the air conditioner takes the sum of the current operating frequency of the air conditioner compressor and the adjustment amplitude as the target operating frequency of the air conditioner compressor.
[0129] When the adjustment trend of the operating frequency of the air conditioner compressor is a decreasing trend, the air conditioner takes the difference between the current operating frequency of the air conditioner compressor and the adjustment amplitude as the target operating frequency of the air conditioner compressor.
[0130] In this solution, when the adjustment trend of the operating frequency of the air-conditioning compressor is an increasing trend, the air conditioner takes the sum of the current operating frequency of the air-conditioning compressor and the adjustment amplitude as the target operating frequency of the air-conditioning compressor. That is, f 目标 = f + Δf. When the adjustment trend of the operating frequency of the air-conditioning compressor is a decreasing trend, the air conditioner takes the difference between the current operating frequency of the air-conditioning compressor and the adjustment amplitude as the target operating frequency of the air-conditioning compressor. That is, f 目标 = f - Δf. With this solution, by comprehensively considering the current operating frequency, adjustment trend and adjustment amplitude of the air-conditioning compressor, the target operating frequency of the compressor is accurately calculated.
[0131] Optionally, the adjustment amplitude is determined by the following method:
[0132] When the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner calculates the adjustment amplitude according to Δf = f × (J 1 - J 2 ) / J 2
[0133] When the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner calculates the adjustment amplitude according to Δf = f × (J 2 - J 1 ) / J 2
[0134] Wherein, Δf is the adjustment amplitude, J 1 is the energy conversion value of the indoor unit of the air conditioner, J 2 is the energy conversion value of the outdoor unit of the air conditioner, and f is the current operating frequency of the air-conditioning compressor.
[0135] In this solution, the adjustment amplitude of the compressor operating frequency can be accurately calculated based on a specific algorithm, ensuring the accuracy of the adjustment of the air-conditioning compressor operating frequency and the effectiveness of energy efficiency optimization.
[0136] In another example, the user can also preset the adjustment amplitude according to the actual situation. With this solution, by reasonably setting the adjustment amplitude, problems such as excessive instantaneous frequency modulation, system instability, increased energy consumption, and equipment loss caused by automatic calculation of the air conditioner can be effectively prevented.
[0137] The embodiments of the present disclosure provide a method for controlling an air-conditioning panel, including:
[0138] The air conditioner determines the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner.
[0139] The air conditioner determines the opening adjustment amplitude of the air-conditioning panel according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner.
[0140] The air conditioner control air conditioner panel adjusts the panel opening degree according to the adjustment range of the opening degree.
[0141] Optionally, after the air conditioner calculates the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, it can combine the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner to determine the adjustment range of the opening degree of the air conditioner panel. Specifically, the air conditioner determines the adjustment range of the opening degree of the air conditioner panel according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, including: the air conditioner compares the energy conversion value of the indoor unit of the air conditioner with the energy conversion value of the outdoor unit of the air conditioner to obtain a comparison result.

In this way, after determining the adjustment range of the opening degree of the air conditioner panel, the air conditioner can control the air conditioner panel to adjust the panel opening degree according to the adjustment range of the opening degree.
[0142] By using the method for controlling the air conditioner panel provided in the embodiments of the present disclosure, by accurately calculating the energy conversion values of the indoor and outdoor units of the air conditioner, determining the adjustment range of the opening degree of the air conditioner panel based on this, and precisely controlling the air conditioner panel based on the adjustment range of the opening degree. With this solution, it can ensure the optimization of the energy conversion between the indoor and outdoor units, not only avoiding energy waste and overloading of equipment, avoiding the imbalance of energy conversion efficiency, but also significantly extending the service life of the air conditioner equipment, comprehensively improving the overall energy efficiency of the system and the user experience.
[0143] Optionally, the air conditioner determines the adjustment range of the opening degree of the air conditioner panel according to the energy conversion value of the indoor unit of the air conditioner and the energy conversion value of the outdoor unit of the air conditioner, including:
[0144] The air conditioner compares the energy conversion value of the indoor unit of the air conditioner with the energy conversion value of the outdoor unit of the air conditioner to obtain a comparison result.
[0145] The air conditioner determines the adjustment range of the opening degree of the air conditioner panel according to the comparison result.
[0146] In this solution, the air conditioner can compare the energy conversion value of the indoor unit of the air conditioner with the energy conversion value of the outdoor unit of the air conditioner to obtain a comparison result. Among them, the comparison result includes that the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, or the energy conversion value of the indoor unit of the air conditioner is equal to the energy conversion value of the outdoor unit of the air conditioner. In this way, the air conditioner can combine the comparison result to determine the adjustment range of the opening degree of the air conditioner panel. Here, the air conditioner determines the adjustment range of the opening degree of the air conditioner panel according to the comparison result, including: when the comparison result is that the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner is based on △α = α×(J 1 -J 2 ) / J 2Determine the adjustment range of the air conditioner panel opening. When the comparison result shows that the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner calculates according to △α = α×(J 2 -J 1 ) / J 2 to determine the adjustment range of the air conditioner panel opening. Wherein, α is the current opening of the air conditioner panel, J 1 is the energy conversion value of the indoor unit of the air conditioner, J 2 is the energy conversion value of the outdoor unit of the air conditioner, and △α is the adjustment range of the air conditioner panel opening. With this solution, it is possible to dynamically balance the energy output of the indoor and outdoor units of the air conditioner, ensure the balance of the energy output of the indoor and outdoor units, improve the overall energy efficiency of the air conditioner, extend the service life of the equipment, and provide a more efficient, energy-saving and stable operation effect of the air conditioner for users.
[0147] Optionally, the air conditioner determines the adjustment range of the air conditioner panel opening according to the comparison result, including:
[0148] When the comparison result shows that the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner calculates according to △α = α×(J 1 -J 2 ) / J 2 to determine the adjustment range of the air conditioner panel opening.
[0149] When the comparison result shows that the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner calculates according to △α = α×(J 2 -J 1 ) / J 2 to determine the adjustment range of the air conditioner panel opening.
[0150] Wherein, α is the current opening of the air conditioner panel, J 1 is the energy conversion value of the indoor unit of the air conditioner, J 2 is the energy conversion value of the outdoor unit of the air conditioner, and △α is the adjustment range of the air conditioner panel opening.
[0151] With this solution, it is possible to accurately calculate the adjustment range of the air conditioner panel opening based on a specific algorithm, ensuring the accuracy of the adjustment of the air conditioner panel opening and the effectiveness of energy efficiency optimization.
[0152] Optionally, the air conditioner controls the air conditioner panel to adjust the panel opening according to the adjustment range of the opening, including:
[0153] When the energy conversion value of the indoor unit of the air conditioner is greater than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner controls the air conditioner panel to reduce the panel opening according to the adjustment range of the opening. Or,
[0154] When the energy conversion value of the indoor unit of the air conditioner is less than the energy conversion value of the outdoor unit of the air conditioner, the air conditioner controls the air conditioner panel to increase the panel opening according to the adjustment range of the opening.
[0155] In this solution, after the air conditioner determines the energy conversion value of the indoor unit and the energy conversion value of the outdoor unit of the air conditioner, the energy conversion value of the indoor unit of the air conditioner can be compared with the energy conversion value of the outdoor unit of the air conditioner. When the energy conversion value of the indoor unit is higher than the energy conversion value of the outdoor unit, it indicates that the air conditioner is operating overloaded. Then, the panel opening can be reduced according to the opening adjustment range to reduce energy input and avoid energy efficiency waste. On the contrary, when the energy conversion value of the indoor unit is lower than the energy conversion value of the outdoor unit, it means that the air conditioner is operating redundantly. Then, the panel opening can be increased according to the opening adjustment range to make full use of the energy provided by the outdoor unit and improve the overall energy efficiency of the air conditioner. The mechanism of this solution can dynamically adjust the panel opening according to the energy conversion difference, ensuring that the energy efficiency of the air conditioner is always maintained at the best state and realizing the efficient utilization and balance of energy.
