Description

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, and in particular to an air conditioning control method, device, electronic equipment and storage medium. Background Technology

[0002] The installation environment of air conditioner outdoor units varies. For example, some air conditioner outdoor units are installed in harsh environments, such as when there are obstacles blocking the air outlet of the air conditioner outdoor unit, or when the air outlet of the air conditioner outdoor unit blows air towards a wall, or when the air outlet of the air conditioner outdoor unit blows air towards the air outlet of another air conditioner outdoor unit. All of these can lead to poor heat dissipation of the air conditioner outdoor unit.

[0003] When the outdoor unit of an air conditioner has poor heat dissipation, the condenser's ability to dissipate heat to the outside decreases, leading to an increase in the air conditioning system pressure and exhaust temperature, which in turn reduces the air conditioner's cooling capacity and results in poor cooling performance, affecting the user experience.

[0081] Embodiments of this disclosure are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0082] The installation environment of air conditioner outdoor units varies. For example, some air conditioner outdoor units are installed in harsh environments, such as when there are obstacles blocking the air outlet of the air conditioner outdoor unit, or when the air outlet of the air conditioner outdoor unit blows air towards a wall, or when the air outlet of the air conditioner outdoor unit blows air towards the air outlet of another air conditioner outdoor unit. All of these can lead to poor heat dissipation of the air conditioner outdoor unit.

[0083] When the outdoor unit of an air conditioner has poor heat dissipation, the condenser's ability to dissipate heat to the outside decreases, leading to an increase in the air conditioning system pressure and exhaust temperature, which in turn reduces the air conditioner's cooling capacity and results in poor cooling performance, affecting the user experience.

[0084] Therefore, in order to solve the problems existing in the related technologies, this disclosure proposes an air conditioning control method. When it is determined that the heat dissipation of the outdoor unit of the air conditioner is abnormal, the speed of the outdoor fan is adjusted according to the mapping relationship between the operating parameters and adjustment values ​​of the outdoor fan, and the speed of the indoor fan is adjusted according to the mapping relationship between the indoor environmental parameters and adjustment values.

[0085] This solution addresses the issue of abnormal heat dissipation in the outdoor unit of an air conditioner by controlling the operating parameters (such as speed) of the outdoor and indoor fans in the air conditioning system. This improves the condenser's ability to dissipate heat, thereby enhancing the air conditioner's cooling capacity and improving the user experience.

[0097] Figure 1 This is a flowchart illustrating an air conditioning control method provided in an embodiment of this disclosure. This method can be applied to air conditioning application scenarios, for example, executed by a processor in an air conditioner with integrated cooling modes or a terminal air conditioner; this disclosure does not limit its application. Figure 1 As shown, the air conditioning control method includes steps 101-102.

[0098] Step 101: If it is determined that the heat dissipation of the outdoor unit of the air conditioner is abnormal, adjust the speed of the outdoor fan according to the mapping relationship between the operating parameters and adjustment values ​​of the outdoor fan.

[0099] The air conditioning control method described in this embodiment is applied to the process of the air conditioner restoring to normal heat dissipation in real time based on the abnormal heat dissipation of the outdoor unit of the air conditioner when the air conditioner starts the cooling mode.

[0100] After confirming abnormal heat dissipation of the outdoor unit of the air conditioner, the operating parameters of various components of the air conditioning system are controlled in a coordinated manner to improve the cooling capacity. In another possible embodiment of this disclosure, after confirming abnormal heat dissipation of the outdoor unit, if controlling only one component's operating parameter can improve the abnormal heat dissipation and restore normal heat dissipation, then controlling only one component's operating parameter is also acceptable. Specifically, this disclosure does not limit the number of operating parameters controlled for each component of the air conditioner.

[0101] The mapping relationship between the operating parameters and adjustment values ​​of the external fan is determined in advance, including but not limited to the following: the magnitude of the speed change, or the target speed to be adjusted; the running time after adjusting the speed once, etc. Specifically, this disclosure does not limit this aspect.

[0102] After adjusting the speed of the outdoor fan according to the mapping relationship between the outdoor fan operating parameters and the adjustment value, the outdoor fan needs to be run at the adjusted speed. After running for the preset time, the outdoor unit of the air conditioner is checked cyclically for any abnormal heat dissipation. If the outdoor unit of the air conditioner is still not experiencing abnormal heat dissipation, the speed of the outdoor fan is adjusted according to the mapping relationship between the outdoor fan operating parameters and the adjustment value until the outdoor unit of the air conditioner dissipates heat normally.

[0103] Step 102: Adjust the speed of the indoor fan according to the mapping relationship between indoor environmental parameters and adjustment values.

[0104] It should be noted that in practical applications, there is no limitation on the order or number of steps to be executed when adjusting the outdoor fan speed in step 101 and adjusting the indoor fan speed in step 102. For example, after confirming that there is an abnormal heat dissipation of the outdoor unit of the air conditioner, step 101 can be used to adjust only the outdoor fan speed; or only step 102 can be used to adjust the indoor fan speed; or, steps 101 and 102 can be executed simultaneously.

[0105] When performing steps 101 and 102 simultaneously, the speed of the indoor fan can be adjusted first, followed by the speed of the outdoor fan. Alternatively, the speed of the outdoor fan can be adjusted first, followed by the speed of the indoor fan. Furthermore, the adjustment of the outdoor fan speed and the adjustment of the indoor fan speed can be performed in parallel. Specifically, this embodiment does not limit the order or number of times the operating parameters of the various components of the air conditioner are controlled.

[0106] The mapping relationship between indoor environmental parameters and adjustment values ​​is determined in advance, including but not limited to the following: the magnitude of the speed change, or the target speed to be adjusted; the running time after adjusting the speed once, etc. Specifically, this disclosure does not limit this aspect.

[0107] After adjusting the indoor fan speed according to the mapping relationship between indoor environmental parameters and adjustment values, the indoor fan needs to be run at the adjusted speed. After running for the preset time, the outdoor unit of the air conditioner is checked cyclically for any abnormal heat dissipation. If the outdoor unit of the air conditioner is still experiencing abnormal heat dissipation, the indoor fan speed is adjusted again according to the mapping relationship between indoor environmental parameters and adjustment values ​​until the outdoor unit of the air conditioner dissipates heat normally.

[0108] In summary, the air conditioning control method proposed in this disclosure includes, when it is determined that the outdoor unit of the air conditioner is experiencing abnormal heat dissipation, adjusting the speed of the outdoor fan according to the mapping relationship between the outdoor fan's operating parameters and adjustment values, and adjusting the speed of the indoor fan according to the mapping relationship between indoor environmental parameters and adjustment values. Similarly, when it is determined that the outdoor unit of the air conditioner is experiencing abnormal heat dissipation, the method adjusts the speed of the outdoor fan according to the mapping relationship between the outdoor fan's operating parameters and adjustment values, and adjusts the speed of the indoor fan according to the mapping relationship between indoor environmental parameters and adjustment values. In the scenario where abnormal heat dissipation of the outdoor unit of the air conditioner is determined, this disclosure improves the problem of abnormal heat dissipation of the outdoor unit by controlling the operating parameters (such as speed) of the outdoor and indoor fans in the air conditioning system in a coordinated manner, thereby enhancing the condenser's heat dissipation capacity and improving the air conditioner's cooling capacity and user experience.

[0109] Figure 2 A flowchart of an air conditioning control method proposed in this disclosure is further shown. Based on Figure 1 The illustrated embodiment further explains step 101. Figure 2 This may include the following steps:

[0110] Step 201: Obtain the first target adjustment value based on the mapping relationship between the external fan operating parameters and the adjustment value.

[0111] The first target adjustment value can be the speed setting to be adjusted, such as the highest speed setting; or it can be the step size for each speed adjustment, such as an increase of 50 rpm, 30 rpm, etc. Specifically, the form of the first target adjustment value is not limited, and any form that can increase the speed of the external fan is within the protection scope of this disclosure.

[0112] Step 202: Adjust the rotational speed of the external fan based on the first target adjustment value.

[0113] Taking the first target adjustment value as the highest speed setting as an example, a control command to increase the speed to the highest speed setting is sent to the external fan processor so that the external fan processor can adjust the speed to the highest speed setting. After the speed of the external fan is adjusted to the highest speed setting, it runs at the highest speed setting for a preset time period. The preset time period is recorded in the mapping relationship between the external fan operating parameters and the adjustment value. For example, the preset time period is 3 minutes, 5 minutes or 10 minutes, etc., and the preset time period of operation is not specifically limited.

[0114] In practical applications, to improve the scenario of abnormal heat dissipation of the outdoor unit of the air conditioner, the speed of the outdoor fan can be adjusted multiple times. When adjusting the speed of the outdoor fan and the corresponding preset time period each time, the first target adjustment value or preset time period can be the same or different for different adjustment sequences. The specific settings can be made according to the installation environment of the outdoor unit of the air conditioner.

[0115] Step 203: After the external fan has been running for a preset period of time based on the adjusted speed, determine whether the operating parameters of the external fan are greater than the preset upper limit threshold.

[0116] If the operating parameters of the external fan are determined to be less than or equal to the preset upper limit threshold, step 204 is executed; if the operating parameters of the external fan are determined to be greater than the preset upper limit threshold, step 205 is executed.

[0117] The purpose of determining the operating parameters of the outdoor fan and the preset upper limit threshold is to prevent the outdoor fan from shutting down due to excessive speed, which would affect the user experience.

[0118] In practical applications, the operating parameters of the outdoor fan include, but are not limited to, the outdoor fan current and the fan module temperature. Therefore, different preset upper limit thresholds are set based on different outdoor fan operating parameters.

[0119] When the outdoor fan operating parameter is the outdoor fan current, determine whether the outdoor fan current is greater than the upper limit threshold of the shutdown current. If the outdoor fan current is less than or equal to the upper limit threshold of the shutdown current, proceed to step 204. If the outdoor fan current is greater than the upper limit threshold of the shutdown current, proceed to step 205. The preset upper limit threshold includes the upper limit threshold of the shutdown current and the upper limit threshold of the shutdown temperature.

[0120] In some embodiments, the upper limit threshold for the shutdown current can be set to the upper limit threshold set at the factory of the air conditioner (e.g., 0.8A, or 0.9A, etc.), or it can be set to a value lower than the upper limit threshold set at the factory of the air conditioner (e.g., 0.8A-0.1A=0.7A, or 0.89-0.1A=0.8A, etc.) to further ensure that the outdoor fan will not trigger automatic shutdown due to an increase in speed. Specifically, the embodiments of this disclosure do not limit the upper limit threshold for the shutdown current.

[0121] When the operating parameter of the external fan is the fan module temperature, determine whether the fan module temperature is greater than the upper limit threshold of the shutdown temperature. If the fan module temperature is less than or equal to the upper limit threshold of the shutdown temperature, proceed to step 204. If the fan module temperature is greater than the upper limit threshold of the shutdown temperature, proceed to step 205.

[0122] In some embodiments, the upper limit threshold for shutdown temperature can be set to 95℃-100℃, or to 96℃-99℃, to ensure that the outdoor fan will not trigger automatic shutdown due to an increase in rotational speed. Specifically, this disclosure does not limit the upper limit threshold for shutdown temperature.

[0123] Step 204: Based on the mapping relationship between the operating parameters and adjustment values ​​of the external fan, continue to increase the speed of the external fan.

[0124] To further optimize the speed of the outdoor fan, the speed of the outdoor fan will be increased to enable the heat dissipation function of the outdoor unit of the air conditioner to return to normal more quickly, improve the heat dissipation capacity of the condenser, and thus improve the user experience.

[0125] The mapping relationship between the operating parameters and adjustment values ​​of the external fan also records the step size for the Nth (greater than 1) increase in the speed of the external fan. Each time, the speed range of the external fan can be set to increase to 30rpm~50rpm, or 40rpm~50rpm, etc., and the specific range is not limited.

[0126] It should be noted that after increasing the speed of the outdoor fan, step 203 needs to be repeated to ensure that the outdoor fan will not shut down due to the increased speed.

[0127] Step 205: Based on the mapping relationship between the operating parameters and adjustment values ​​of the external fan, reduce the speed of the external fan.

[0128] The purpose of lowering the outdoor fan speed is to prevent the outdoor fan from shutting down automatically.

[0129] The mapping relationship between the operating parameters and adjustment values ​​of the external fan also records the step size for the Nth (greater than 1) reduction of the external fan speed. Each time, the speed range of the external fan can be set to be reduced from 10rpm to 30rpm, or from 25rpm to 45rpm, etc., and the specific range is not limited.

[0130] Figure 3 A flowchart of an air conditioning control method proposed in this disclosure is further shown. Based on Figure 1 The illustrated embodiment further explains step 102. Figure 3 This may include the following steps:

[0131] Step 301: Determine the indoor temperature difference based on the current indoor temperature and the initial indoor temperature.

[0132] If the indoor temperature difference is determined to be greater than or equal to the cooling temperature difference threshold, step 302 is executed; if the indoor temperature difference is determined to be less than the cooling temperature difference threshold, step 304 is executed.

[0133] To further improve the indoor cooling effect, the indoor temperature was collected as the initial indoor temperature T after the air conditioner was turned on. 初始内环 When collecting indoor temperature data, sensors may be used, but are not limited to, for data collection; no specific method is specified.

[0134] After the indoor fan speed is set to the user-defined preset running time (5-20 minutes), the current indoor temperature T is collected again. 当前内环 Calculate T 初始内环 With T 当前内环 The difference T 降温温差 If T 初始内环 -T 当前内环 ≥T 降温温差 If so, proceed to step 302, indicating that the indoor temperature can continue to decrease. If T 初始内环 -T 当前内环 <T 降温温差 If so, proceed to step 304, indicating that the indoor temperature cannot be lowered further.

[0135] In some embodiments, the temperature difference threshold T 降温温差 It can be set to 1-3℃, or 2-5℃, etc., and there is no specific limitation.

[0136] Step 302: Determine the second target adjustment value based on the mapping relationship between the indoor environmental parameters and the adjustment value.

[0137] The second target adjustment value can be the speed setting to be adjusted, such as the highest speed setting; or it can be the step size for each adjustment, such as an increase of 50 rpm, 30 rpm, etc. Specifically, the form of the second target adjustment value is not limited, and any form that can increase the internal fan speed falls within the protection scope of this disclosure.

[0138] Step 303: Adjust the rotational speed of the internal fan based on the second target adjustment value.

[0139] Taking the second target adjustment value as the highest speed setting as an example, a control command is sent to the indoor fan processor to increase the speed to the highest level, so that the indoor fan processor can adjust the speed to the highest level. After adjusting to the highest level, it runs at the highest level for a preset time period. The preset time period is recorded in the mapping relationship between indoor environmental parameters and adjustment values. For example, the preset time period is 3 minutes, 5 minutes or 10 minutes, etc., and the preset time period is not specifically limited.

[0140] In practical applications, to improve the scenario of abnormal heat dissipation of the indoor unit of the air conditioner, it may be necessary to adjust the speed of the indoor fan multiple times. When adjusting the speed of the indoor fan and the corresponding preset time period each time, the second target adjustment value or preset time period may be the same or different for different adjustment sequences. The specific settings can be made according to the installation environment of the indoor unit of the air conditioner.

[0141] Step 304: Obtain the temperature of the inner tube of the evaporator and determine whether the temperature of the inner tube is greater than the high-load inner tube temperature threshold.

[0142] In T 初始内环 -T 当前内环 <T 降温温差 This indicates that the indoor temperature cannot be lowered further, the air conditioner's cooling effect is insufficient, and priority should be given to ensuring the evaporator's outlet air temperature.

[0143] Collect the inner tube temperature T of the evaporator 内管 And determine the inner tube temperature T 内管 Is it greater than the high-load inner tube temperature threshold T? 高负荷内管 In this embodiment of the disclosure, T 高负荷内管 The specific size is not limited.

[0144] When T 内管≤ T 高负荷内管 At that time, the internal fan speed is maintained at its original speed. When T 内管 >T 高负荷内管 At that time, proceed to step 305.

[0145] Step 305: When it is determined that the inner pipe temperature is greater than the high-load inner pipe temperature threshold, the speed of the inner fan is reduced until the inner pipe temperature is less than or equal to the high-load inner pipe temperature threshold.

[0146] In some embodiments, when reducing the speed of the internal fan, the step size for reducing the speed is set in different time periods. For example, the speed of the internal fan is reduced by 30 rpm to 100 rpm within 30s to 180s; or the speed of the internal fan is reduced by 30 rpm to 50 rpm within 60s to 120s, etc. The present disclosure does not limit the strategy for reducing the speed of the internal fan.

[0147] After the air conditioner is turned on, the system checks whether the outdoor unit's heat dissipation is abnormal. If abnormal heat dissipation is confirmed, the air conditioner is controlled using any of the above embodiments. Therefore, determining whether the outdoor unit's heat dissipation is abnormal is a prerequisite for activating the air conditioner's control function. In some embodiments, determining whether the outdoor unit's heat dissipation is abnormal can be done through any one or a combination of the following three methods, including:

[0148] Method 1: Determine whether the outdoor unit of the air conditioner is experiencing abnormal heat dissipation based on the difference between the current outdoor ambient temperature and the outdoor ambient temperature when the unit is turned on.

[0149] Record the initial outer loop T when the air conditioner is turned on. 开机外环 After the air conditioner has been running for the preset time (e.g., 5-30 minutes), record the current outdoor ambient temperature T. 外环 Compared to T 外环 With T 开机外环 The difference, such as T 外环 -T 开机外环 >T 外机散热不良温差1 If the temperature is 3-8℃, it means that after the outdoor unit of the air conditioner is turned on, the ambient temperature of the outdoor unit gradually increases, which indicates that the outdoor unit has poor heat dissipation (abnormal).

[0150] Method 2: Determine whether the outdoor unit of the air conditioner is experiencing abnormal heat dissipation based on the difference between the current outdoor ambient temperature and the meteorological temperature.

[0151] Record the current outdoor ambient temperature T after the air conditioner has been running for a preset time (5-30 minutes). 外环 And calculate T 外环 -Local weather temperature > T 外机散热不良温差2 If the temperature is 3-8℃, it indicates that the current outdoor ambient temperature of the air conditioner outdoor unit is higher than the local meteorological temperature, which means that the outdoor unit is not dissipating heat well.

[0152] In some embodiments, local weather temperature can be obtained through network connection or by sensor collection; however, this disclosure does not limit the specific details.

[0153] Method 3: Determine whether the outdoor unit of the air conditioner is experiencing abnormal heat dissipation based on the trend of outdoor ambient temperature changes within a unit of time.

[0154] Record T after the air conditioner has been running for a preset time (e.g., 5-30 minutes). 当前外环 The outdoor temperature T before the preset running time 外环0 , such as T 当前外环 -T 外环0 >T 外机散热不良温差3 If the temperature is 2-6℃, it means that the ambient temperature gradually increases after the outdoor unit of the air conditioner is turned on, which indicates that the outdoor unit has poor heat dissipation.

[0155] It should be noted that the operating time and various thresholds mentioned when judging whether there is an abnormal heat dissipation in the outdoor unit of the air conditioner are illustrative examples, not specific numerical limits.

[0156] In some embodiments, when it is determined that the outdoor unit of the air conditioner is experiencing abnormal heat dissipation, in addition to adjusting the speed of the outdoor fan and the indoor fan, the compressor and the electronic expansion valve can also be controlled in a coordinated manner to improve the problem of abnormal heat dissipation.

[0157] If abnormal heat dissipation of the outdoor unit is confirmed, the control will remove the restrictions on the compressor's operating frequency and the evaporator's anti-freeze function. At the factory, the compressor frequency upper limit F for each fan speed is set. 频率上限 To extend the lifespan of the air conditioner, however, when the outdoor unit of the air conditioner experiences abnormal heat dissipation, in order to improve the air conditioner's cooling performance, it is necessary to control and remove the compressor frequency upper limit F for each fan speed setting. 频率上限 If the user sets the fan speed compressor frequency to a low fan speed frequency, the maximum frequency limit during normal operation is only 50 Hz. When it is determined that the outdoor unit of the air conditioner is not dissipating heat properly (abnormally), the fan speed compressor frequency limit is canceled, and the frequency can run up to the current highest frequency of the outer ring, 70 Hz. Specifically, this embodiment does not limit the value of the compressor frequency.

[0158] Similarly, to protect the evaporator from freezing due to low temperatures during air conditioner operation, the evaporator anti-freeze function can be enabled. However, if abnormal heat dissipation of the outdoor unit is detected, the restriction on evaporator anti-freeze can be removed to improve the heat dissipation problem and enhance air conditioning cooling.

[0159] If abnormal heat dissipation of the outdoor unit of the air conditioner is determined, adjust the opening of the electronic expansion valve. In some embodiments, if the throttling device uses an electronic expansion valve, the cooling target exhaust temperature calculated by the air conditioning system is adjusted to the highest cooling target exhaust temperature (e.g., 95℃-105℃). The opening of the electronic expansion valve is controlled according to the air conditioner's built-in program (reducing the opening) to further reduce the evaporator pipe temperature and improve the cooling effect. If the evaporator temperature T inside the pipe rises during the valve closing process, it indicates that the refrigeration system is overheating and the valve cannot be closed further. In this case, the electronic expansion valve is adjusted back to the previously adjusted opening and maintained.

[0160] Figure 4 A flowchart of an air conditioning control method proposed in this disclosure is further shown, including:

[0161] Step 401: Determine if the outdoor unit of the air conditioner is experiencing abnormal heat dissipation.

[0162] For the specific judgment process, please refer to the detailed description of methods one to three in the above embodiments, so it will not be repeated here.

[0163] Step 402: When it is determined that the heat dissipation of the outdoor unit of the air conditioner is abnormal, the abnormality level of the heat dissipation of the outdoor unit of the air conditioner is determined.

[0164] In practical applications, when it is determined that the heat dissipation of the outdoor unit of the air conditioner is abnormal, the ambient temperature of the outdoor unit is collected, and the ambient temperature of the outdoor unit is classified into abnormal levels, for example, into 3 levels or 4 levels.

[0165] Specifically, a one-to-one correspondence between the ambient temperature of the outdoor unit of the air conditioner and the abnormality level can be preset. However, the embodiments disclosed herein do not limit the ambient temperature of the outdoor unit of the air conditioner and the abnormality level.

[0166] Step 403: Determine the corresponding target linkage control combination based on the abnormality level. The linkage control combination includes at least two combinations of the following: control of the external fan, control of the internal fan, control of the compressor and the evaporator, and control of the electronic expansion valve.

[0167] The linkage control combination can be the linkage of two components, including the linkage between the outdoor fan and the indoor fan, the linkage between the outdoor fan and the compressor, the linkage between the outdoor fan and the electronic expansion, the linkage between the indoor fan and the compressor, the linkage between the indoor fan and the evaporator, the linkage between the indoor fan and the electronic expansion, and the linkage between the compressor and the evaporator, etc.

[0168] The linkage control combination can also be used for the linkage of three components, including the linkage of the outdoor fan, the indoor fan and the electronic expansion, the linkage of the outdoor fan, the indoor fan and the evaporator, etc.

[0169] The linkage control combination can also link four components, including the linkage of the outdoor fan, indoor fan, electronic expansion and evaporator, etc.

[0170] In addition, the outdoor fan, indoor fan, electronic expander, or evaporator can be controlled separately to improve the problem of poor heat dissipation of the outdoor unit of the air conditioner.
