Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.
[0050] At present, with the rapid development of the field of air conditioner technology, air conditioners capable of low-temperature refrigeration have emerged. Among them, the low-temperature refrigeration function of the air conditioner is to meet the cold load demand of the indoor and outdoor direct heat exchange space under low outdoor climate conditions due to the large indoor heat source or the need for preservation or refrigeration, and it is not suitable for indoor and outdoor direct heat exchange. It is a low-load refrigeration. However, the compressor displacement of some air conditioners is small, and the refrigerant filling ratio is relatively high, which makes the oil and liquid return effect of the compressor running at low load deviate, the superheat of the bottom of the compressor is insufficient, and the operating reliability is reduced. Therefore, it is necessary to use intermittent start and stop of the external fan to solve the problem of insufficient superheat of the bottom of the compressor during low-load refrigeration. However, when the temperature sensing package of the external pipe of the air conditioner fails or loosens, the increase in the temperature of the external pipe cannot be detected after the fan is stopped, so the air conditioner cannot be properly controlled, resulting in continuous increase in system pressure and external pipe temperature, which seriously endangers the reliability of system operation.
[0051] Based on this, the present application proposes an air conditioning control method, device, equipment and computer-readable storage medium to solve the technical problem in the prior art that the air conditioner cannot be properly controlled after the temperature sensing package of the air conditioner's outer pipe fails.
[0052] The air-conditioning control method in the embodiment of the present invention is applied to an air-conditioning control device, which is arranged in an air-conditioning control device. The air-conditioning control device is provided with one or more processors, memories, and one or more applications, wherein the one or more applications are stored in the memories and are configured to be executed by the processor to implement the air-conditioning control method; wherein the air-conditioning control device can be an intelligent terminal that is communicatively connected with a target air conditioner to control the target air conditioner, such as a mobile phone, a tablet computer, a network device, and a smart computer; optionally, the air-conditioning control device can also be the main control module of the target air conditioner itself.
[0053] like Figure 1 As shown, Figure 1 The following is a schematic diagram of a scenario of the air conditioning control method of the present application embodiment. The air conditioning control scenario in the present invention embodiment includes an air conditioning control device 100 (an air conditioning control device is integrated in the air conditioning control device 100) and a target air conditioner 200. A computer-readable storage medium corresponding to the air conditioning control method is run in the air conditioning control device 100 to execute the steps of the air conditioning control method. The target air conditioner 200 is an intelligent air conditioner that is connected to the air conditioning control device 100 in communication and can perform corresponding operations according to the operation instructions of the air conditioning control device 100.
[0054] Understandably, Figure 1The air-conditioning control equipment in the air-conditioning control method scenario shown, or the devices included in the air-conditioning control equipment, does not constitute a limitation on the embodiments of the present invention, that is, the number and type of air-conditioning control equipment included in the air-conditioning control method scenario, or the number and type of devices included in each device, do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be regarded as equivalent replacements or derivatives of the technical solution claimed to be protected by the embodiments of the present invention.
[0055] The air conditioning control device 100 in the embodiment of the present invention is mainly used to: respond to an air conditioning low temperature control request for a target air conditioner, detect the outer pipe temperature sensing package of the target air conditioner, and determine the sensing package state of the outer pipe temperature sensing package;
[0056] If the state of the temperature sensing package is the temperature sensing package failure state, determining the phase current correction protection value of the target air conditioner according to the exhaust temperature, AC current value and preset phase current protection strategy of the target air conditioner;
[0057] The air-conditioning operation state of the target air-conditioner is adjusted according to the current phase current of the target air-conditioner and the phase current correction protection value to obtain an air-conditioning control result.
[0058] The embodiments of the present application provide an air conditioning control method, apparatus, device, and computer-readable storage medium, which are described in detail below.
[0059] It can be understood by those skilled in the art that Figure 1 The application environment shown in is only one of the application scenarios related to the present application solution and does not constitute a limitation on the application scenario of the present application solution. Other application environments may also include Figure 1 More or fewer air conditioning control devices, or air conditioning control network connection relationships shown, such as Figure 1 Only one air conditioning control device is shown. It can be understood that the scenario of the air conditioning control method can also include one or more air conditioning control devices, which is not limited here. The air conditioning control device 100 can also include a memory for storing air conditioning operation data and other data.
[0060] It should be noted that Figure 1 The scene diagram of the air-conditioning control method shown is only an example. The scene of the air-conditioning control method described in the embodiment of the present invention is to more clearly illustrate the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention.
[0061] Based on the scenario of the above air-conditioning control method, various embodiments of the air-conditioning control method disclosed in the present invention are proposed.
[0062] like Figure 2 As shown, Figure 2This is a flow chart of an embodiment of an air conditioning control method in an embodiment of the present application. The air conditioning control method includes the following steps 201 to 203:
[0063] 201. In response to an air-conditioning low temperature control request for a target air-conditioner, detecting an outer tube temperature sensing package of the target air-conditioner to determine a sensing package state of the outer tube temperature sensing package;
[0064] The air conditioning control method in this embodiment is applied to air conditioning control equipment, and the type and number of air conditioning control equipment are not specifically limited, that is, the air conditioning control equipment can be an intelligent terminal that communicates with the target air conditioner to control the target air conditioner, such as a mobile phone, a tablet computer, a network device, and a smart computer; optionally, the air conditioning control equipment can also be the main control module of the target air conditioner itself. Among them, the target air conditioner is a variety of intelligent air conditioners with low-temperature refrigeration function and equipped with a start-stop external fan. Among them, the low-temperature refrigeration function refers to the target air conditioner being able to meet the cold load requirements of the indoor and outdoor direct heat exchange space under low outdoor climate conditions due to the large indoor heat source or the need for preservation or refrigeration, and it is not suitable for indoor and outdoor direct heat exchange. It is a low-load refrigeration mode. Among them, the start-stop external fan is an external fan that can respond to the control refrigeration of the target air conditioner to perform intermittent start-stop operations. The start-stop external fan can use the hysteresis of the bottom temperature of the compressor of the target air conditioner in the low-temperature refrigeration mode compared with the system high pressure change to meet the bottom superheat of part of the time for corresponding shutdown and startup operations, thereby solving the problem of insufficient superheat at the bottom of the compressor during low-load refrigeration.
[0065] Specifically, when the target air conditioner is running in the low-temperature cooling mode, the temperature sensing package of the outer tube temperature may fail or become loose, resulting in the target air conditioner being unable to detect the change amplitude of the outer tube temperature after switching the start-stop outer fan to the shutdown mode, which will cause the air conditioner system pressure and the outer tube temperature to continue to rise, and there is a risk of excessive compressor pressure and pipe burst, which will seriously endanger the reliability of system operation. Therefore, when the target air conditioner is running in the low-temperature cooling mode, it responds to the air conditioning low-temperature control request for the target air conditioner, wherein the air conditioning low-temperature control request is an operation instruction for driving the target air conditioner to detect the temperature sensing package state of the outer tube temperature sensing package in real time, and to execute the corresponding protection control measures when the temperature sensing package state is abnormal. Among them, the triggering method of the air conditioning low-temperature control request is not specifically limited here, that is, the air conditioning low-temperature control request can be actively triggered by the user, for example, the user actively triggers the air conditioning low-temperature control request by clicking the low-temperature control button on the remote control device connected to the target air conditioner. Optionally, the air conditioning low-temperature control request can also be automatically triggered by the target air conditioner, for example, the target air conditioner is provided with a low-temperature control process, and the air conditioning low-temperature control request is automatically triggered during the operation of the air conditioner.
[0066] Specifically, after receiving the air-conditioning low temperature control request, the target air conditioner detects the external pipe temperature sensing package of the target air conditioner, thereby determining the sensing package state of the external pipe temperature sensing package, and then in the subsequent steps, timely control is performed on the start and stop of the external fan according to the sensing package state to avoid the safety hazards of excessive pressure in the air-conditioning system and excessive external pipe temperature. The external pipe temperature sensing package is a sensing package component provided on the external coil of the target air conditioner, and is used to detect the coil temperature of the external coil.
[0067] Specifically, during the operation of the target air conditioner, when the exhaust temperature changes, the outer tube temperature sensing package of the target air conditioner is detected to obtain the sensing package state of the outer tube temperature sensing package.
[0068] Optionally, if the exhaust temperature of the target air conditioner is on an upward trend, the target air conditioner reads the current external coil temperature. If the external coil temperature changes accordingly with the exhaust temperature, the target air conditioner determines that the temperature sensing bag state of the external tube temperature sensing bag is the temperature sensing bag effective state, and there is no need to perform protection control on the start and stop of the external fan.
[0069] Optionally, if the exhaust temperature of the target air conditioner is on an upward trend, the target air conditioner reads the current external coil temperature. If the external coil temperature of the external tube temperature sensor remains basically unchanged, that is, the external coil temperature change value is less than the preset change threshold, then the target air conditioner determines that the temperature sensor state of the external tube temperature sensor is a temperature sensor failure state, and it is necessary to perform protection control on the start and stop of the external fan of the target air conditioner.
[0070] 202. If the state of the temperature sensing package is a temperature sensing package failure state, determining a phase current correction protection value of the target air conditioner according to the exhaust temperature, the AC current value and a preset phase current protection strategy of the target air conditioner;
[0071] Specifically, when the target air conditioner determines that the temperature sensing package state of the external pipe temperature sensing package is the temperature sensing package failure state, the terminal also determines the phase current protection value of the target air conditioner according to the exhaust temperature, AC current value and preset phase current protection strategy of the target air conditioner. Among them, the preset phase current protection strategy is a control strategy that includes the corresponding exhaust frequency reduction protection value, AC current frequency reduction protection value and phase current protection value and corresponding coefficients, and performs operation protection on the target air conditioner based on the phase current of the target air conditioner.
[0072] Specifically, since the target air conditioner may be a small or medium-sized air conditioner, in this case, it is usually difficult to achieve the protection parameters corresponding to the exhaust temperature and the AC current value for the low-load cooling of the target air conditioner, and the cost of adding a pressure detection device to this type of air conditioner is relatively high. Moreover, during the operation of the external coil temperature sensor package loose or abnormal operation, the high load of the compressor customer service system of the target air conditioner generates a large amount of additional work, and the phase current first system compliance is more significantly affected. Therefore, in this embodiment, when the temperature sensor package state of the external tube temperature sensor package of the target air conditioner is the temperature sensor failure state, the phase current protection strategy is used to control the operation of the target air conditioner, so that when the system pressure exceeds the compressor stall pressure when the external coil temperature sensor package fails, the phase current protection can be effectively performed to improve the operating stability of the target air conditioner.
[0073] Specifically, when the target air conditioner determines that the temperature sensor state of the external pipe temperature sensor is the temperature sensor failure state, the exhaust temperature of the target air conditioner and the AC current value of the target air conditioner are obtained, and the phase current correction protection value of the target air conditioner is determined by the exhaust temperature and the AC current value, and the phase current correction protection value is used to control the external fan of the target air conditioner in a subsequent step, so that when the external pipe temperature sensor is in the temperature sensor failure state, the phase current correction protection value can be used to control the start and stop of the external fan operation, thereby quickly reducing the system pressure and external pipe temperature of the target air conditioner.
[0074] Specifically, after obtaining the exhaust temperature and AC current value of the target air conditioner, the terminal also determines the target exhaust temperature protection value according to the exhaust temperature and the exhaust frequency reduction protection value in the preset phase current protection strategy. The exhaust frequency reduction protection value is a threshold parameter for frequency reduction protection of the target air conditioner according to the exhaust temperature.
[0075] Specifically, after obtaining the exhaust temperature of the target air conditioner, the terminal determines the exhaust protection coefficient based on the exhaust temperature and the exhaust frequency reduction protection value. That is, the terminal calculates the exhaust temperature divided by the exhaust frequency reduction protection value to obtain the ratio of the exhaust temperature to the exhaust frequency reduction protection value, and determines the ratio of the exhaust temperature to the exhaust frequency reduction protection value as the exhaust protection coefficient of the target air conditioner.
[0076] Specifically, after obtaining the exhaust protection coefficient, the terminal also uses the exhaust protection coefficient to correct and adjust the exhaust frequency reduction protection value to obtain a target exhaust temperature protection value. That is, the terminal calculates the product between the exhaust protection coefficient and the exhaust frequency reduction protection value to obtain a target exhaust temperature protection value. The target exhaust temperature protection value is an exhaust temperature parameter to be used to correct the phase current protection value of the target air conditioner.
[0077] Specifically, after obtaining the AC current value of the target air conditioner, the terminal determines the target AC protection value based on the AC current value and the AC frequency reduction protection value in the preset phase current protection strategy, wherein the AC frequency reduction protection value is a threshold parameter for frequency reduction protection of the target air conditioner based on the AC current value.
[0078] Specifically, after obtaining the AC current value, the terminal calculates the ratio between the AC current value and the AC frequency reduction protection value in the preset phase current protection strategy, that is, the terminal divides the AC current value by the AC frequency reduction protection value to obtain the AC protection coefficient.
[0079] Specifically, after obtaining the AC protection coefficient, the terminal also uses the AC protection coefficient to correct and adjust the AC frequency reduction protection value to obtain a target AC protection value. That is, the terminal calculates the product between the AC protection coefficient and the AC frequency reduction protection value to obtain the target AC protection value. The target AC protection value is the AC current parameter to be used to correct the phase current protection value of the target air conditioner.
[0080] Specifically, after obtaining the target exhaust temperature protection value and the target AC current protection value, the terminal also uses the target exhaust temperature protection value and the target AC current protection value to adjust the phase current protection value in the preset phase current protection strategy to obtain a corrected phase current correction protection value, wherein the phase current correction protection value is determined according to the real-time exhaust temperature state and AC current value state of the target air conditioner, and is a phase current threshold parameter that can perform phase current protection on the target air conditioner.
[0081] 203. Adjust the air-conditioning operation state of the target air-conditioner according to the current phase current of the target air-conditioner and the phase current correction protection value to obtain an air-conditioning control result.
[0082] Specifically, after acquiring the phase current protection value corresponding to the target air conditioner, the terminal also adjusts the air-conditioning operation state of the target air conditioner according to the current phase current of the target air conditioner and the phase current correction protection value to obtain the air-conditioning control result.
[0083] Specifically, after determining the phase current protection value, the terminal also obtains the current phase current of the target air conditioner and the external fan status of the start and stop external fan of the target air conditioner in real time, and adjusts the external fan status and other operating parameters of the target air conditioner according to the comparison result of the current phase current and the phase current protection value, so that when the external pipe temperature sensing package fails abnormally and the compressor frequency increases, the air-conditioning system pressure and external pipe temperature can be quickly reduced, thereby reducing the probability of safety accidents.
[0084] Optionally, if the current phase current of the target air conditioner is lower than the phase current protection value, the current compressor load of the target air conditioner at the terminal is low, and the phase current protection of the target air conditioner is not performed, that is, the original operating logic of the target air conditioner is maintained and continues to run, and the air conditioning control result without the need for phase current protection control is output.
[0085] Optionally, if the current phase current of the target air conditioner is greater than or equal to the phase current protection value, and the external fan state is in the shutdown state. The terminal determines that the current compressor load of the target air conditioner is high, and there may be a risk of compressor overload and external coil explosion. Therefore, the terminal needs to perform phase current protection on the target air conditioner, that is, the terminal switches the external fan state to the start state, and corrects the external fan state according to the preset external fan gear, so that the start-stop external fan can start quickly and run at the preset external wind gear, so that the system pressure and external pipe temperature of the target air conditioner can be quickly reduced to reduce the probability of accidents, and output the air conditioning control result corresponding to the phase current protection control.
[0086] Optionally, in other embodiments, the target air conditioner can also adjust other operating parameters of the target air conditioner according to the comparison result between the current phase current and the phase current protection value, so as to further improve the operating stability of the target air conditioner.
[0087] In this embodiment, the air conditioning control device detects the outer tube temperature sensing package of the target air conditioner in response to the air conditioning low temperature control request for the target air conditioner, and determines the sensing package state of the outer tube temperature sensing package; if the sensing package state is the sensing package failure state, the phase current correction protection value of the target air conditioner is determined according to the exhaust temperature, AC current value and preset phase current protection strategy of the target air conditioner; the air conditioning operation state of the target air conditioner is adjusted according to the current phase current of the target air conditioner and the phase current correction protection value to obtain the air conditioning control result. When the outer tube temperature sensing package of the air conditioner fails abnormally or becomes loose, the phase current correction protection value of the target air conditioner is determined according to the exhaust temperature and AC current value. When the outer disk sensing package fails, the phase current correction protection value and the current phase current can be used to timely perform phase current protection on the target air conditioner in the low temperature cooling state, and effectively control the start and stop state of the outer fan of the target air conditioner, thereby improving the system reliability of the air conditioner in the low temperature cooling operation.
[0088] like Figure 3 As shown, Figure 3 This is a flow chart of an embodiment of determining a phase current correction protection value in an air conditioning control method provided in an embodiment of the present application. Specifically, in this embodiment, the air conditioning control method further includes steps 301 to 303:
[0089] 301. Obtaining a phase current protection value of the target air conditioner in a preset phase current protection strategy;
[0090] 302. Access a preset phase current protection database to obtain a phase current correction coefficient associated with the target exhaust temperature protection value and the target alternating current protection value;
[0091] 303. Correct the phase current protection value according to the phase current correction coefficient to obtain a phase current correction protection value.
[0092] Based on the above embodiments, in this embodiment, after obtaining the target exhaust temperature protection value and the target AC power protection value, the terminal also uses the target exhaust temperature protection value and the target AC power protection value to adjust the phase current protection value in the preset phase current protection strategy to obtain a corrected phase current correction protection value, wherein the phase current correction protection value is determined according to the real-time exhaust temperature state and AC current value state of the target air conditioner, and is a phase current threshold parameter that can perform phase current protection on the target air conditioner.
[0093] Specifically, after obtaining the target exhaust temperature protection value and the target AC power protection value, the terminal also obtains the phase current protection value of the target air conditioner in the preset phase current protection strategy, wherein the phase current protection value is the uncorrected phase current protection threshold value in the target air conditioner. When performing phase current protection on the target air conditioner, it is necessary to correct the phase current protection value according to the real-time operating status of the target air conditioner to obtain a phase current corrected protection value.
[0094] Specifically, a phase current protection database is preset in the terminal or the target air conditioner, and the phase current protection database stores a database table of corresponding mapping relationships between different target exhaust temperatures, target AC protection values, and specified phase current correction coefficients. As shown in Table 1, Table 1 is a data table corresponding to an embodiment of the phase current protection database.
[0095]
[0096] Table 1
[0097] Among them, the target exhaust temperature protection value A1 to the target exhaust temperature protection value A4 represent the target exhaust temperature protection values corresponding to different exhaust temperature protection coefficients, wherein among the target exhaust temperature protection value A1 to the target exhaust temperature protection value A4, the target exhaust temperature protection value gradually increases with the size of the sequence number.
[0098] Among them, the target AC power protection value B1 to the target AC power protection value B4 represent the target exhaust temperature protection values corresponding to different exhaust temperature protection coefficients. Among the target AC power protection value B1 to the target AC power protection value B4, the target exhaust temperature protection value gradually increases with the size of the sequence number.
[0099] Among them, the phase current correction coefficient X1 to the phase current correction coefficient X6 are phase current correction coefficients representing different proportions.
[0100] Specifically, after obtaining the target exhaust temperature protection value and the target AC power protection value, the terminal accesses the phase current protection database to obtain the phase current correction coefficient associated with the target exhaust temperature protection value and the target AC power protection value in the phase current protection database, wherein the phase current correction coefficient is a correction coefficient for correcting the phase current protection value.
[0101] Specifically, after obtaining the phase current correction coefficient, the terminal corrects the phase current protection value according to the phase current correction coefficient to obtain a phase current correction protection value that conforms to the current operating state of the target air conditioner, and adjusts the air-conditioning operating state of the target air conditioner according to the current phase current of the target air conditioner and the phase current correction protection value to obtain the air-conditioning control result.
[0102] In this embodiment, the air conditioning control device obtains the phase current protection value of the target air conditioner in the preset phase current protection strategy; accesses the preset phase current protection database to obtain the phase current correction coefficient associated with the target exhaust temperature protection value and the target AC protection value; and corrects the phase current protection value according to the phase current correction coefficient to obtain the phase current correction protection value. The phase current correction protection value that meets the current operating state of the target air conditioner is determined according to the target exhaust temperature protection value and the target AC protection value, so as to improve the accuracy of air conditioning control and further improve the stability of air conditioning operation.
[0103] like Figure 4 As shown, Figure 4 This is a flow chart of an embodiment of generating a phase current protection strategy in the air conditioning control method provided in the embodiment of the present application. Specifically, in this embodiment, the air conditioning control method further includes steps 401 to 403:
[0104] 401. Collecting the test external coil temperature of the target air conditioner under the target test condition;
[0105] 402. If the test external coil temperature is greater than or equal to the test external coil frequency reduction protection temperature, the external fan state of the start / stop external fan of the target air conditioner is switched to the start state, and the test exhaust temperature, test AC current and test phase current of the target air conditioner are read;
[0106] 403. Generate a preset phase current protection strategy according to the test exhaust temperature, the test alternating current, and the test phase current.
[0107] Based on the above embodiment, in this embodiment, since there are great differences in the configurations and working systems of different air conditioners, the AC frequency reduction protection value, the exhaust temperature frequency reduction protection value and the phase current protection value of different air conditioners will be adjusted as the system changes. Therefore, before the target air conditioner performs the phase current protection control, the target air conditioner is also tested according to the target test condition to generate a preset phase current protection strategy.
[0108] Specifically, the terminal reads the target test condition, drives the target air conditioner to operate under the target test condition, and collects the test external coil temperature of the target air conditioner under the target test condition. Among them, the preset condition is that when the external disk temperature sensing package is in the temperature sensing package effective state, the target air conditioner is driven to operate under the low temperature condition with the external fan state of the external fan being stopped when the external fan state of the external fan is started and stopped. Among them, the low temperature condition is the condition state corresponding to the highest operating frequency of the compressor of the target air conditioner. In a specific embodiment, the low temperature condition is -15°C (unit: degrees Celsius).
[0109] Specifically, after the terminal obtains the test external coil temperature of the target air conditioner, it compares the test external coil temperature with the test external disk frequency reduction protection temperature. If the test external coil temperature is greater than or equal to the test external disk frequency reduction protection temperature, the external fan state of the start-stop external fan of the target air conditioner is switched to the start state, and the test exhaust temperature, test AC current and test phase current of the target air conditioner are read.
[0110] Specifically, the terminal further adjusts the test external disk frequency reduction temperature that switches the external fan state to the start state, and collects the test exhaust temperature, test AC current and test phase current of the adjusted target air conditioner. Optionally, the adjustment method can be to subtract the temperature difference parameter of the corresponding multiple from the test external disk frequency reduction temperature, and obtain the test exhaust temperature, test AC current and test phase current of the target air conditioner under the corresponding endorsed temperature difference parameter.
[0111] Specifically, after obtaining each test exhaust temperature, each test AC current and each test phase current, the terminal also determines the exhaust temperature protection coefficient, exhaust temperature frequency reduction protection value, AC protection coefficient, AC frequency reduction protection value, test phase current protection value and test phase current protection coefficient of the target air conditioner according to each test exhaust temperature, each test AC current and each test phase current, so as to generate the phase current protection strategy, and in subsequent steps, perform phase current protection on the target air conditioner according to the phase current protection strategy when the external coil temperature sensor is abnormal.
[0112] In this embodiment, the air conditioning control device collects the test external coil temperature of the target air conditioner under the target test condition; if the test external coil temperature is greater than or equal to the test external coil frequency reduction protection temperature, the external fan state of the start-stop external fan of the target air conditioner is switched to the start state, and the test exhaust temperature, test AC current and test phase current of the target air conditioner are read; a preset phase current protection strategy is generated according to the test exhaust temperature, the test AC current and the test phase current. The preset phase current protection strategy is generated according to the operating parameters of the target air conditioner under the corresponding target test condition, providing data support for subsequent phase current protection to improve the control accuracy of phase current protection.
