Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, specifically to an air conditioner compressor preheating control method, device, air conditioner, and computer medium. Background Technology

[0002] When an air conditioner is in a low-temperature environment, the miscibility between the compressor oil and the refrigerant decreases, resulting in oil stratification and increased kinematic viscosity. This leads to difficulty in starting the compressor. At the same time, the lubricating oil in the compressor becomes less effective in low-temperature environments, and there may be a large accumulation of liquid refrigerant. Starting the compressor under these conditions can cause irreversible wear. Therefore, when an air conditioner compressor is operating at a low temperature, it needs to be preheated.

[0003] Currently, commonly used compressor preheating technologies for low temperatures fall into two categories: one uses crankshaft electric heating belts for external heating, and the other achieves self-preheating through compressor coil current. The former has low heating efficiency and adds crankshaft electric heating belts to the entire system, resulting in poor economic efficiency; the latter heats internally and achieves preheating by controlling the preheating current, but preset control is inconvenient. In other words, it is currently impossible to accurately control compressor preheating under low-temperature operating conditions. In low-temperature environments, air conditioner compressors cannot start and run normally, which can easily lead to compressor damage and shorten the service life of the air conditioner. Summary of the Invention

[0004] This application provides a method, apparatus, air conditioner, and computer medium for controlling the preheating of an air conditioner compressor, aiming to solve the technical problem that the existing air conditioner compressor preheating control is unreasonable, which prevents the air conditioner compressor from starting and running normally, resulting in compressor damage and a short service life of the air conditioner.

[0005] On the one hand, this application provides a preheating control method for an air conditioner compressor, the preheating control method for an air conditioner compressor including the following steps:

[0006] Collect the outer ring temperature and exhaust temperature;

[0007] If the outer ring temperature is lower than the preset first ambient temperature and the exhaust temperature is lower than the preset first exhaust temperature, then query the historical preheating records to obtain the heat dissipation duration corresponding to the last preheating.

[0008] If the heat dissipation time exceeds the preset time threshold, the preheating parameters are determined based on the outer ring temperature, and the preheating operation is performed according to the preheating parameters.

[0009] In some embodiments of this application,

[0010] If the heat dissipation time exceeds a preset time threshold, then the preheating parameters are determined based on the outer ring temperature, and a preheating operation is performed according to the preheating parameters. The method then includes:

[0011] When the air conditioner compressor starts the preheating operation, new outer ring temperature and new exhaust temperature are collected;

[0012] If the new outer ring temperature is greater than the preset second ambient temperature, and / or the new exhaust temperature is greater than the preset second exhaust temperature, then the preheating operation is terminated.

[0013] When the termination of the preheating operation is detected, a timing operation is performed to count the heat dissipation time, and the heat dissipation time is saved to the historical preheating record.

[0014] In some embodiments of this application, the step of controlling the termination of the preheating operation if the new outer ring temperature is greater than a preset second ambient temperature, and / or the new exhaust temperature is greater than a preset second exhaust temperature, includes:

[0015] If the new outer ring temperature is greater than the preset second ambient temperature, and / or the new exhaust temperature is greater than the preset second exhaust temperature, then the current compressor temperature of the compressor in the air conditioner is obtained, wherein the current compressor temperature is the average temperature detected by multiple temperature sensing devices installed on the compressor.

[0016] Compare the current compressor temperature with the preset second exhaust temperature;

[0017] If the current compressor temperature is greater than the preset second exhaust temperature, the preheating operation is terminated.

[0018] In some embodiments of this application, if the outer ring temperature is less than a preset first ambient temperature and the exhaust temperature is less than a preset first exhaust temperature, then after querying historical preheating records and obtaining the heat dissipation duration corresponding to the last preheating, the method includes:

[0020] Query the preset parameter and duration mapping relationship to obtain the duration threshold corresponding to the preheating parameter;

[0021] Compare the heat dissipation time corresponding to the last preheating with the time threshold corresponding to the preheating parameter;

[0022] If the heat dissipation time does not exceed the time threshold, the compressor of the air conditioner will be locked to prevent the preheating operation from being performed.

[0023] In some embodiments of this application, before querying the preset parameter and duration mapping relationship and obtaining the duration threshold corresponding to the preheating parameter, the method includes:

[0024] The actual compressor temperature after preheating with different preheating parameters under different outer ring temperatures was collected;

[0025] Obtain the preset target compressor temperature, and calculate the compressor temperature difference between the actual compressor temperature and the target compressor temperature;

[0026] Obtain the preset compressor temperature change rate under different outer ring temperatures, and calculate the duration threshold under different outer ring temperatures according to the compressor temperature change rate and the compressor temperature difference;

[0027] The outer ring temperature and the corresponding duration threshold are associated and saved to generate a preset parameter and duration mapping relationship.

[0028] In some embodiments of this application, if the heat dissipation time exceeds a preset time threshold, then determining preheating parameters based on the outer ring temperature and performing a preheating operation according to the preheating parameters includes:

[0029] If the heat dissipation time exceeds the preset time threshold, then query the preset temperature and parameter correspondence to obtain the target preheating parameter corresponding to the outer ring temperature;

[0030] The compressor of the air conditioner is preheated according to the heating current and heating time in the target preheating parameters.

[0031] In some embodiments of this application, before querying the preset temperature and parameter correspondence to obtain the target preheating parameter corresponding to the outer ring temperature if the heat dissipation time exceeds a preset time threshold, the method includes:

[0032] The startup time, startup success rate, and compressor wear rate of the air conditioner compressor were collected under different external ambient temperatures.

[0033] Obtain the target ambient temperature with the shortest startup time, the highest startup success rate, and / or the lowest compressor wear rate, and calculate the temperature difference between each outer ring temperature and the target ambient temperature.

[0034] Query the preset temperature and current change rules to obtain the heating current and heating time corresponding to the temperature difference;

[0035] The outer ring temperature is correlated with the heating current and the heating time to generate a preset temperature and parameter correspondence.

[0036] On the other hand, this application also provides an air conditioner compressor preheating control device, the air conditioner compressor preheating control device comprising:

[0037] Temperature acquisition module, used to acquire outer ring temperature and exhaust temperature;

[0038] The duration acquisition module is used to query historical preheating records and obtain the heat dissipation duration corresponding to the last preheating if the outer ring temperature is less than the preset first ambient temperature and the exhaust temperature is less than the preset first exhaust temperature.

[0039] The preheating control module is used to determine preheating parameters based on the outer ring temperature and perform preheating operations according to the preheating parameters if the heat dissipation time exceeds a preset time threshold.

[0040] On the other hand, this application also provides an air conditioner, which includes any one or more local servers, edge nodes, and end-side devices, and the air conditioner is equipped with:

[0041] One or more processors;

[0042] Memory; and

[0043] One or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the processor to implement the air conditioner compressor preheating control method.

[0044] On the other hand, this application also provides a computer medium having a computer program stored thereon, the computer program being loaded by a processor to execute the steps in the air conditioner compressor preheating control method.

[0045] The air conditioner compressor preheating control method provided in this application includes: collecting the outer ring temperature and the exhaust temperature; if the outer ring temperature is lower than a preset first ambient temperature and the exhaust temperature is lower than a preset first exhaust temperature, then querying historical preheating records to obtain the heat dissipation time corresponding to the last preheating; if the heat dissipation time exceeds a preset time threshold, then determining preheating parameters based on the outer ring temperature and performing preheating operations according to the preheating parameters. In this embodiment, the outer ring temperature, exhaust temperature, and heat dissipation time are comprehensively considered before compressor preheating to determine whether to perform a preheating operation. This takes into account both the outer ring temperature and the compressor's heat dissipation time, allowing for intermittent preheating operations during low-temperature compressor operation, making the compressor preheating time more accurate. Simultaneously, when it is determined that preheating operations are needed, preheating parameters are determined based on the outer ring temperature. This ensures that the preheating operation allows the compressor to reach its most suitable operating conditions, making the preheating operation more reasonable, effectively avoiding damage caused by low-temperature compressor operation, and extending the compressor's service life.

It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0058] This application provides an air conditioner compressor preheating control method, device, air conditioner, and computer medium, which will be described in detail below.

[0059] The air conditioner compressor preheating control method in this embodiment of the invention is applied to an air conditioner compressor preheating control device, which is installed in an air conditioner. The air conditioner is equipped with one or more processors, a memory, and one or more application programs, wherein one or more application programs are stored in the memory and configured to be executed by the processor to implement the air conditioner compressor preheating control method; the air conditioner can be a single unit or a multi-split unit.

[0060] like Figure 1 As shown, Figure 1This is a schematic diagram of the scenario in which the air conditioner compressor preheating control method is executed according to an embodiment of this application. The air conditioner compressor preheating control scenario in this embodiment includes an air conditioner 100 (the air conditioner 100 integrates an air conditioner compressor preheating control device), and the computer medium in the air conditioner 100 runs the air conditioner compressor preheating control to execute the steps of air conditioner compressor preheating control.

[0061] Understandable, Figure 1 The air conditioner in the specific scenario of the air conditioner compressor preheating control method shown, or the device contained in the air conditioner, does not constitute a limitation on the embodiments of the present invention. That is, the number of devices or types of air conditioners contained in the specific scenario of the air conditioner compressor preheating control method, or the number or types of devices contained in each device, do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be considered as equivalent substitutions or derivatives of the technical solutions claimed in the embodiments of the present invention.

[0062] In this embodiment of the invention, the air conditioner 100 is mainly used for: collecting the outer ring temperature and the exhaust temperature; if the outer ring temperature is less than a preset first ambient temperature and the exhaust temperature is less than a preset first exhaust temperature, then querying historical preheating records to obtain the heat dissipation duration corresponding to the last preheating; if the heat dissipation duration exceeds a preset duration threshold, then determining preheating parameters based on the outer ring temperature and performing preheating operations according to the preheating parameters.

[0063] In this embodiment of the invention, the air conditioner 100 can be a standalone air conditioner, or it can be an air conditioner network or air conditioner cluster. For example, the air conditioner 100 described in this embodiment of the invention includes, but is not limited to, a computer, a network host, a single network air conditioner, a set of multiple network air conditioners, or a cloud air conditioner composed of multiple air conditioners. The cloud air conditioner is composed of a large number of computers or network air conditioners based on cloud computing.

[0064] Those skilled in the art will understand that Figure 1 The application environment shown is merely one application scenario of the solution in this application and does not constitute a limitation on the application scenario of the solution in this application. Other application environments may include those that are more specific to this application.

It is understood that the specific scenario of the air conditioner compressor preheating control method may also include one or more other air conditioners, which are not limited here. The air conditioner 100 may also include a memory for storing data.

[0065] Furthermore, in specific scenarios of the air conditioner compressor preheating control method of this application, the air conditioner 100 may be equipped with a display device, or the air conditioner 100 may not have a display device but may communicate with an external display device 200. The display device 200 is used to output the results of the air conditioner compressor preheating control method executed in the air conditioner. The air conditioner 100 can access a background database 300, which may be located in the air conditioner's local storage or in the cloud. The background database 300 stores information related to the air conditioner compressor preheating control.

[0066] It should be noted that, Figure 1 The schematic diagram illustrating the scenario of the air conditioner compressor preheating control method is merely an example. The specific scenario of the air conditioner compressor preheating control method described in this embodiment of the invention is intended to more clearly illustrate the technical solution of this embodiment and does not constitute a limitation on the technical solution provided by this embodiment of the invention.

[0067] Based on the specific scenarios of the above-mentioned air conditioner compressor preheating control method, an embodiment of the air conditioner compressor preheating control method is proposed.

[0068] like Figure 2 As shown, Figure 2 This is a schematic flowchart of an embodiment of the preheating control method in the air conditioner compressor preheating control method of this application.

[0069] In this embodiment, the air conditioner compressor preheating control method includes steps 201 to 203:

[0070] 201. Collect the outer ring temperature and exhaust temperature.

[0071] The air conditioner compressor preheating control method in this embodiment is applied to air conditioners, and the type of air conditioner is not specifically limited.

[0072] When an air conditioner compressor operates in a low-temperature environment, it undergoes intermittent heating. If the preheating time is too short, the compressor will not reach the set temperature; conversely, if the heating time is too long, the compressor's preheating temperature will be too high. Both of these situations can damage the compressor upon startup. Existing technologies can accurately control the compressor preheating time, allowing it to heat from one temperature to another. However, the compressor heating interval is difficult to determine precisely. If the heating interval is too long, the compressor will become too cold; if the heating interval is too short, the compressor's heat will not be fully dissipated, causing the compressor's temperature to rise continuously. Based on this, the technical solution proposed in the embodiments of this application is presented.

[0073] The air conditioner receives a preheating control command. The triggering method of the preheating control command is not specifically limited. That is, the preheating control command can be triggered actively by the user, such as by the user pressing the "Preheating Control" button on the air conditioner remote control. In addition, the preheating control command can also be triggered automatically by the air conditioner. For example, if the air conditioner is preset to automatically trigger the preheating control command from October to February of the following year, then the air conditioner collects time information and automatically triggers the preheating control command when it detects that it is from October to February of the following year.

[0074] After receiving the preheating control command, the air conditioner collects the outer ring temperature and exhaust temperature. The outer ring temperature refers to the ambient temperature around the air conditioner compressor. When the compressor is not running, the outer ring temperature equals the ambient temperature. When the air conditioner is running, the outer ring temperature is determined by both the ambient temperature and the compressor temperature. For example, if the ambient temperature is -20℃ and the compressor temperature is 20℃, the outer ring temperature is 10℃. Exhaust temperature protection is a type of compressor temperature protection. That is, during compressor preheating, if the exhaust temperature detected at the compressor outlet is too high, the compressor preheating is terminated. Alternatively, if preheating during compressor operation causes the exhaust temperature to exceed the normal value, it will increase compressor power consumption, cause carbon buildup in the lubricating oil, degrade performance, and affect the normal operation of the compressor. In this case, the compressor preheating is terminated. To avoid excessively high compressor exhaust temperature due to compressor preheating, this embodiment collects the outer ring temperature and exhaust temperature, combining them to determine whether to perform a compressor preheating operation. Specifically:

[0075] 202. If the outer ring temperature is less than the preset first ambient temperature and the exhaust temperature is less than the preset first exhaust temperature, then query the historical preheating records to obtain the heat dissipation time corresponding to the last preheating.

[0076] The air conditioner compares the outer ring temperature with the preset first ambient temperature, which refers to the critical ambient temperature for compressor preheating. For example, if the preset first ambient temperature is set to -15℃, and the outer ring temperature is lower than the preset first ambient temperature, it indicates that the miscibility between the compressor oil and refrigerant has deteriorated, resulting in oil stratification and increased kinematic viscosity. This can easily lead to reliability risks such as difficulty in starting the compressor and accelerated wear. If the outer ring temperature is greater than or equal to the preset first ambient temperature, it indicates that the compressor can work normally.

[0077] The air conditioner compares the exhaust temperature with the preset first exhaust temperature. The preset first exhaust temperature is the temperature at which the compressor operates normally and prevents the lubricating oil from carbonizing. For example, if the preset first exhaust temperature is set to 10℃, if the exhaust temperature is lower than the preset first exhaust temperature, it means that the compressor is operating at a lower temperature; if the exhaust temperature is greater than or equal to the preset first exhaust temperature, it means that the compressor is in normal operating condition.

[0078] If the outer ring temperature is lower than the preset first ambient temperature and the exhaust temperature is lower than the preset first exhaust temperature, the air conditioner will query the historical preheating records to obtain the heat dissipation time corresponding to the last preheating. That is, in this embodiment, if the ring temperature and exhaust temperature both meet the requirements, it can be determined that the compressor may be in an unsuitable working state at low temperature.

[0079] The air conditioner can query its historical preheating records, which contain historical preheating information, such as the preheating information for the current day. This information includes the preheating start time, preheating end time, preheating duration, and preheating current, among other things.

[0080] The air conditioner obtains the end time of the last preheating, subtracts the end time of the preheating from the current time to obtain the heat dissipation time. The air conditioner compares the heat dissipation time with a preset time threshold. The preset time threshold refers to the appropriate heat dissipation time for the compressor. If the compressor does not perform the next preheating without the interval of the time threshold, heat accumulation in the compressor may occur. For example, the time threshold is set to 30 minutes.

[0081] 203. If the heat dissipation time exceeds the preset time threshold, the preheating parameters are determined according to the outer ring temperature, and the preheating operation is performed according to the preheating parameters.

[0082] If the heat dissipation time exceeds the preset time threshold, the air conditioner determines the preheating parameters based on the outer ring temperature. The preheating parameters include heating time and heating current. The method by which the air conditioner determines the preheating parameters based on the outer ring temperature is not limited. For example, if the air conditioner has a temperature and parameter mapping table, the air conditioner queries the temperature and parameter mapping table to obtain the preheating parameters corresponding to the outer ring temperature, and the air conditioner performs the preheating operation according to the heating current and heating time in the preheating parameters.

[0083] In this embodiment, the outer ring temperature, exhaust temperature, and heat dissipation time are comprehensively considered before the compressor preheats to determine whether to perform a preheating operation. This takes into account both the outer ring temperature and the compressor's heat dissipation time, allowing for intermittent preheating operations during low-temperature operation of the compressor. This makes the timing of the compressor preheating operation more accurate. At the same time, when it is determined that a preheating operation is required, the preheating parameters are determined based on the outer ring temperature. This preheating operation allows the compressor to reach its most suitable operating conditions, making the preheating operation more reasonable and effectively avoiding damage caused by low-temperature operation of the compressor, thus extending the compressor's service life.

[0084] like Figure 3 As shown, Figure 3 This is a schematic flowchart of an embodiment of the preheating control method for an air conditioner compressor in this application, illustrating the termination of the preheating operation.

[0085] In some embodiments of this application, after the air conditioner compressor preheating control method performs the preheating operation, in order to prevent the compressor from overheating, it is necessary to terminate the following steps 301 to 303 in a timely manner:

[0086] 301. When the air conditioner compressor starts the preheating operation, new outer ring temperature and new exhaust temperature are collected.

[0087] When the air conditioner compressor starts the preheating operation, the air conditioner collects new ambient temperature and new exhaust temperature. The air conditioner can collect these data in real time or after a set time. For example, after the preheating operation, the air conditioner collects new ambient temperature and new exhaust temperature every 5 seconds.

[0088] The air conditioner compares the new outer ambient temperature with the preset second ambient temperature. The preset second ambient temperature refers to the critical ambient temperature for compressor preheating. For example, if the preset second ambient temperature is set to -10℃, and the outer ambient temperature is lower than the preset second ambient temperature, it indicates that the miscibility between the compressor oil and refrigerant has deteriorated, leading to oil stratification and increased kinematic viscosity. This can easily cause reliability risks such as difficulty starting the compressor and accelerated wear. If the outer ambient temperature is greater than or equal to the preset second ambient temperature, it means the compressor can operate normally. It is understandable that the preset second ambient temperature is higher than the preset first ambient temperature.

[0089] The air conditioner compares the new exhaust temperature with the preset second exhaust temperature. The preset second exhaust temperature is the temperature at which the compressor operates normally and to prevent lubricating oil carbon buildup. For example, if the preset second exhaust temperature is set to 0°C, and the exhaust temperature is lower than the preset second exhaust temperature, it indicates that the compressor is operating at a lower temperature. If the exhaust temperature is greater than or equal to the preset second exhaust temperature, it indicates that the compressor is operating normally. It is understandable that the preset second exhaust temperature is lower than the preset first exhaust temperature.

[0090] 302. If the new outer ring temperature is greater than the preset second ambient temperature, and / or the new exhaust temperature is greater than the preset second exhaust temperature, then control to terminate the preheating operation.

[0091] If the new outer ring temperature is greater than the preset second ambient temperature, and / or the new exhaust temperature is greater than the preset second exhaust temperature, the preheating operation is terminated. In this embodiment, the preheating is terminated by using the new outer ring temperature and the new exhaust temperature, which can avoid overheating of the compressor caused by excessive preheating and keep the compressor at the most suitable operating temperature.

[0092] Furthermore, the air conditioner's preheating exit is more accurate. In this embodiment, multiple temperature detection devices can be installed in the compressor. The air conditioner determines whether to exit preheating based on the compressor temperature detected by these multiple devices. Specifically, this includes:

[0093] (1) If the new outer ring temperature is greater than the preset second ambient temperature, and / or the new exhaust temperature is greater than the preset second exhaust temperature, then the current compressor temperature of the compressor in the air conditioner is obtained, wherein the current compressor temperature is the average temperature detected by multiple temperature sensing devices installed on the compressor.

[0094] (2) Compare the current compressor temperature with the preset second exhaust temperature;

[0095] (3) If the current compressor temperature is greater than the preset second exhaust temperature, the preheating operation is terminated.

[0096] That is, if the new outer ambient temperature is greater than the preset second ambient temperature, and / or the new exhaust temperature is greater than the preset second exhaust temperature, the air conditioner obtains the compressor temperature, where the current compressor temperature is the average of the temperatures detected by multiple temperature sensors installed on the compressor. The air conditioner compares the compressor temperature with the preset second exhaust temperature; if the compressor temperature is greater than the preset second exhaust temperature, the preheating operation is terminated; if the compressor temperature is less than or equal to the preset second exhaust temperature, the preheating operation continues.

[0097] like Figure 4 As shown, Figure 4 This is a schematic diagram of specific parameters in an embodiment of the air conditioner compressor preheating control method provided in this application, which controls preheating based on exhaust temperature and compressor temperature. The diagram includes exhaust temperature and compressor temperature. The compressor temperature is determined by the average value of the top pressure temperature of the compressor, the middle pressure temperature of the compressor, the bottom pressure temperature of the compressor, and pressure 1 and pressure 2 at any position, detected by multiple temperature detection devices.

[0098] 303. When the termination of the preheating operation is detected, a timing operation is performed to count the heat dissipation time and the heat dissipation time is saved to the historical preheating record.

[0099] When the preheating operation is detected to be terminated, the air conditioner performs a timing operation to record the heat dissipation time, and saves the heat dissipation time to the historical preheating record. In this embodiment, the air conditioner records the heat dissipation time, which avoids the situation where the compressor frequently heats up when the outer ring temperature is too low, leading to heat accumulation in the compressor, by relying solely on the outer ring temperature.

[0100] Reference Figure 5 , Figure 5 This is a flowchart illustrating an embodiment of the air conditioner compressor preheating control method provided in this application, which determines preheating parameters based on the outer ring temperature.

[0101] In some embodiments of this application, the process of determining preheating parameters based on the outer ring temperature in an air conditioner is specifically described, including steps 401 to 404:

[0102] 401. Query the historical preheating record to obtain the preheating parameters of the last preheating, wherein the preheating parameters include: heating current and heating duration.

[0103] The air conditioner queries historical preheating records to obtain the preheating parameters for the last preheating, including heating current and heating duration. Based on these parameters, the air conditioner determines the final temperature after compressor preheating.

[0104] 402. Query the preset parameter and duration mapping relationship to obtain the duration threshold corresponding to the preheating parameter.

[0105] The preset parameter and duration mapping relationship in the air conditioner refers to the preheating parameter and duration mapping relationship set in advance in the air conditioner. This embodiment provides a specific implementation of constructing the preset parameter and duration mapping relationship, including:

[0106] (1) Collect the actual compressor temperature after preheating with different preheating parameters under different outer ring temperatures;

[0107] (2) Obtain the preset target compressor temperature and calculate the compressor temperature difference between the actual compressor temperature and the target compressor temperature;

[0108] (3) Obtain the preset compressor temperature change rate under different outer ring temperatures, and calculate the duration threshold under different outer ring temperatures according to the compressor temperature change rate and the compressor temperature difference;

[0109] (4) Associate and save the outer ring temperature and the corresponding duration threshold to generate a preset parameter and duration mapping relationship.

[0110] Specifically, the system first collects the actual compressor temperature after preheating with different preheating parameters under different outer ring temperatures; then, it obtains the preset target compressor temperature and calculates the compressor temperature difference between the actual and target compressor temperatures; finally, it obtains the compressor temperature change rate under different outer ring temperatures and calculates the set duration threshold under different outer ring temperatures based on the compressor temperature change rate and compressor temperature difference; and then associates and saves the outer ring temperature and the corresponding duration threshold to generate a preset parameter-duration mapping relationship. In this embodiment, by pre-storing the setting parameters and duration mapping relationship in the air conditioner's memory, different duration thresholds can be set under different preheating parameters. When the preheating parameters are determined, the air conditioner can set the preheating duration according to the mapping relationship, making the compressor preheating more accurate and avoiding frequent compressor preheating.

[0111] The air conditioner queries the preset parameter and duration mapping relationship, and obtains the duration threshold corresponding to the preheating parameters.

[0112] 403, compare the heat dissipation time corresponding to the last preheating with the time threshold corresponding to the preheating parameter.

[0113] 404. If the heat dissipation time does not exceed the time threshold, the compressor of the air conditioner will be locked to prevent the preheating operation from being performed.

[0114] The air conditioner compares the heat dissipation time corresponding to the last preheating with the time threshold corresponding to the preheating parameter. If the heat dissipation time does not exceed the time threshold, the air conditioner's compressor is locked to prevent preheating. If the heat dissipation time exceeds the time threshold, the air conditioner's compressor performs preheating. This embodiment can effectively avoid the accumulation of heat in the air conditioner's compressor caused by frequent preheating.

[0115] Reference Figure 6 , Figure 6 This is a flowchart illustrating an embodiment of the preheating parameter setting in the air conditioner compressor preheating control method provided in this application.

[0116] In some embodiments of this application, the determination of preheating parameters further includes the following steps 501-502:

[0117] 501. If the heat dissipation time exceeds the preset time threshold, then query the preset temperature and parameter correspondence to obtain the target preheating parameter corresponding to the outer ring temperature.

[0118] In this embodiment, the air conditioner has a preset temperature and parameter correspondence relationship. This relationship refers to the suitable heating parameters of the air conditioner under different external ambient temperatures. Specifically, this embodiment provides a step-by-step guide for setting preheating parameters, including:

[0119] (1) Collect data on the start-up time, start-up success rate, and compressor wear rate of the air conditioner compressor under different external ambient temperatures;

[0120] (2) Obtain the target ambient temperature with the shortest startup time, the highest startup success rate and / or the lowest compressor wear rate, and calculate the temperature difference between each outer ring temperature and the target ambient temperature;

[0121] (3) Query the preset temperature and current change rules to obtain the heating current and heating time corresponding to the temperature difference;

[0122] (4) Associate the outer ring temperature with the heating current and the heating time to generate a preset temperature and parameter correspondence.

[0123] Specifically, the air conditioner collects data on the compressor's start-up time, start-up success rate, and compressor wear rate under different ambient temperatures over a period of time (e.g., one month, one quarter). The air conditioner obtains the target ambient temperature with the shortest start-up time, highest start-up success rate, and / or lowest compressor wear rate. The compressor calculates the temperature difference between each ambient temperature and the target ambient temperature. The air conditioner queries a preset temperature-current change rule to obtain the heating current and heating time corresponding to the temperature difference. The air conditioner correlates the ambient temperature with the heating current and heating time to generate a preset temperature-parameter correspondence. In this embodiment, the temperature-parameter correspondence is set based on the ambient temperature to set accurate preheating parameters, making compressor preheating more reasonable.

[0124] 502. Perform a preheating operation on the compressor of the air conditioner according to the heating current and heating time in the target preheating parameters.

[0125] The air conditioner performs a preheating operation on the compressor according to the heating current and heating time in the target preheating parameters, making the preheating more reasonable and avoiding the problem of excessive heating time. When it is determined that a preheating operation is required, the preheating parameters are determined based on the outer ring temperature. This preheating operation allows the compressor to reach the most suitable operating conditions, making the preheating operation more reasonable and effectively avoiding damage caused by the compressor operating at low temperatures, thus extending the compressor's service life.

[0127]

[0128] That is, for ease of understanding, this embodiment provides a specific scenario for an air conditioner compressor preheating control method. The preheating entry and exit conditions in this embodiment are as follows:

[0129] For self-preheating entry, the outer ring temperature and exhaust temperature are considered as the entry conditions, as follows:

[0130] 1) Detect outer ring temperature < -15℃; 2) Detect exhaust temperature < 10℃

[0131] Preheating begins when both conditions 1 and 2 are met.

[0132] The self-preheating termination considerations take the outer ring temperature and exhaust temperature as the self-preheating termination conditions, as follows:

[0133] 1) Detect outer ring temperature ≥ -10℃; 2) Detect exhaust temperature ≥ 0℃

[0134] If either condition 1 or 2 is met, the preheating process will terminate.

[0135] Furthermore, to prevent overheating or excessively long heating times, this embodiment can collect the temperature of the heating coil to ensure the effectiveness of heating. Specifically, this embodiment provides a coil heating parameter, as shown in the table below:

[0136] Table 2: Maximum Coil Temperature During Preheating Process

[0137]

[0138] like Figure 7 As shown, Figure 7 This is a schematic diagram of an embodiment of an air conditioner compressor preheating control device.

[0139] To better implement the air conditioner compressor preheating control method in this application embodiment, based on the air conditioner compressor preheating control method, this application embodiment also provides an air conditioner compressor preheating control device, which includes the following modules 601-603:

[0140] Temperature acquisition module 601 is used to acquire outer ring temperature and exhaust temperature;

[0141] The duration acquisition module 602 is used to query historical preheating records and obtain the heat dissipation duration corresponding to the last preheating if the outer ring temperature is less than the preset first ambient temperature and the exhaust temperature is less than the preset first exhaust temperature.

[0142] The preheating control module 603 is used to determine preheating parameters based on the outer ring temperature and perform preheating operations according to the preheating parameters if the heat dissipation time exceeds a preset time threshold.

[0143] In some embodiments of this application, the air conditioner compressor preheating control device includes:

[0144] When the air conditioner compressor starts the preheating operation, new outer ring temperature and new exhaust temperature are collected;

[0145] If the new outer ring temperature is greater than the preset second ambient temperature, and / or the new exhaust temperature is greater than the preset second exhaust temperature, then the preheating operation is terminated.

[0146] When the termination of the preheating operation is detected, a timing operation is performed to count the heat dissipation time, and the heat dissipation time is saved to the historical preheating record.

[0147] In some embodiments of this application, the air conditioner compressor preheating control device performs the step of controlling the termination of the preheating operation if the new outer ambient temperature is greater than a preset second ambient temperature and / or the new exhaust temperature is greater than a preset second exhaust temperature, including:

[0148] If the new outer ring temperature is greater than the preset second ambient temperature, and / or the new exhaust temperature is greater than the preset second exhaust temperature, then the current compressor temperature of the compressor in the air conditioner is obtained, wherein the current compressor temperature is the average temperature detected by multiple temperature sensing devices installed on the compressor.

[0149] Compare the current compressor temperature with the preset second exhaust temperature;

[0150] If the current compressor temperature is greater than the preset second exhaust temperature, the preheating operation is terminated.

[0151] In some embodiments of this application, the air conditioner compressor preheating control device includes:

[0152] Query the historical preheating records to obtain the preheating parameters of the last preheating, wherein the preheating parameters include: heating current and heating duration;

[0153] Query the preset parameter and duration mapping relationship to obtain the duration threshold corresponding to the preheating parameter;

[0154] Compare the heat dissipation time corresponding to the last preheating with the time threshold corresponding to the preheating parameter;

[0155] If the heat dissipation time does not exceed the time threshold, the compressor of the air conditioner will be locked to prevent the preheating operation from being performed.

[0156] In some embodiments of this application, the air conditioner compressor preheating control device includes:

[0157] The actual compressor temperature after preheating with different preheating parameters under different outer ring temperatures was collected;

[0158] Obtain the preset target compressor temperature, and calculate the compressor temperature difference between the actual compressor temperature and the target compressor temperature;

[0159] Obtain the preset compressor temperature change rate under different outer ring temperatures, and calculate the duration threshold under different outer ring temperatures according to the compressor temperature change rate and the compressor temperature difference;

[0160] The outer ring temperature and the corresponding duration threshold are associated and saved to generate a preset parameter and duration mapping relationship.

[0161] In some embodiments of this application, the preheating control module 603 includes:

[0162] If the heat dissipation time exceeds the preset time threshold, then query the preset temperature and parameter correspondence to obtain the target preheating parameter corresponding to the outer ring temperature;

[0163] The compressor of the air conditioner is preheated according to the heating current and heating time in the target preheating parameters.

[0164] In some embodiments of this application, the air conditioner compressor preheating control device includes:

[0165] The startup time, startup success rate, and compressor wear rate of the air conditioner compressor were collected under different external ambient temperatures.

[0166] Obtain the target ambient temperature with the shortest startup time, the highest startup success rate, and / or the lowest compressor wear rate, and calculate the temperature difference between each outer ring temperature and the target ambient temperature.

[0167] Query the preset temperature and current change rules to obtain the heating current and heating time corresponding to the temperature difference;

[0168] The outer ring temperature is correlated with the heating current and the heating time to generate a preset temperature and parameter correspondence.

[0169] In this embodiment of the air conditioner compressor preheating control device, the outer ring temperature, exhaust temperature, and heat dissipation time are comprehensively considered before the compressor preheats to determine whether to perform a preheating operation. This takes into account both the outer ring temperature and the compressor's heat dissipation time, allowing for intermittent preheating operations during low-temperature operation of the compressor. This makes the timing of the compressor preheating operation more accurate. At the same time, when it is determined that a preheating operation is required, the preheating parameters are determined based on the outer ring temperature. This preheating operation allows the compressor to reach its most suitable operating condition, making the preheating operation more reasonable and effectively avoiding damage caused by low-temperature operation of the compressor, thus extending the compressor's service life.
