Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to a control method for shutting down an air conditioner, an air conditioner, and a readable storage medium. Background Art

[0002] At present, when the air conditioner receives a shutdown command, it controls the compressor to directly drop from the current operating frequency to 0Hz and shut down. This shutdown processing method has little impact on the compressor and other components of the air conditioner system when the current operating frequency of the compressor is low, and does not have a significant impact on the reliability and operating performance of the air conditioner. However, if the current operating frequency of the compressor is high, the pressure of the entire refrigerant circulation system of the air conditioner is high. If the compressor is shut down directly, the system pressure cannot be released, which is not only not conducive to the system load allocation, but also has a great impact on the compressor, which will reduce the performance of the compressor and shorten the service life of the compressor. Therefore, it will cause the service life and operating performance of the air conditioner to decrease.

[0003] In the related art, a common method for implementing soft shutdown control of an air-conditioning compressor includes: in response to a shutdown instruction for instructing the compressor to shut down, controlling the switch to a shutdown mode, the shutdown mode including: adjusting the flow opening of the air-conditioning throttling device to a set shutdown flow opening, adjusting the operating frequency of the compressor to a set shutdown frequency; and controlling the compressor to shut down.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] According to the shutdown command, before controlling the compressor to shut down, the flow rate and the operating frequency of the compressor are controlled first. Although the compressor is not directly controlled to shut down, entering the shutdown mode in response to the shutdown command will inevitably increase the energy consumption of the equipment and affect the user experience.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0039] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0041] The system for executing the control method includes: a processor and a memory storing program instructions. It may also include a communication interface and a bus. The processor, the communication interface, and the memory can communicate with each other through the bus. The communication interface can be used for information transmission. The processor is configured to execute the control method for shutting down the air conditioner when running the program instructions.

[0042] Combination Figure 1 As shown, the embodiment of the present disclosure provides a control method for stopping an air conditioner, comprising:

[0043] S110: The processor determines a shutdown type in response to a shutdown request.

[0044] S120: The processor obtains operating parameters of the air conditioner corresponding to the shutdown type according to the shutdown type.

[0045] S130: The processor controls the operation of the air conditioner according to the operating parameters.

[0046] The control method for air conditioner shutdown provided by the present disclosure responds to a shutdown request, determines the shutdown type according to the shutdown request, obtains the operating parameters corresponding to the shutdown type according to the current shutdown type, and controls the air conditioner operation to perform the shutdown operation according to the current operating parameters.

[0047] The control method for air conditioner shutdown provided by the embodiment of the present disclosure is used to determine the shutdown type according to the shutdown request. The air conditioner is controlled to perform the shutdown operation by adjusting the operating parameters corresponding to the shutdown type. In this way, the operating parameters of the air conditioner to be adjusted can be selected in a targeted manner according to the shutdown type, so that the operating parameters can meet the shutdown conditions corresponding to the current shutdown type, thereby effectively reducing the impact of the shutdown on the air conditioner and improving the overall safety performance and working reliability of the regulator.

[0048] Furthermore, compared to the related art, in which a shutdown command is received and the frequency of the compressor and the system flow are adjusted, the control method of the present application first determines the shutdown type, and then adjusts the operating parameters of the air conditioner in a targeted manner according to the shutdown type, so as to determine the shutdown operation that matches the different shutdown types, effectively reduce the impact on the air conditioner, and reduce the system energy consumption.

[0049] Optionally, according to the shutdown type, the step of acquiring the operating parameters of the air conditioner corresponding to the shutdown type includes: when the shutdown type is normal shutdown, acquiring the operating frequency f and the exhaust temperature T of the compressor.

[0050] In this embodiment, when the shutdown type is normal shutdown, the compressor is controlled to operate according to the control logic of normal shutdown by obtaining the operating frequency f and exhaust temperature T of the compressor. The magnitude of the operating frequency f directly reflects the workload and energy efficiency of the compressor. By selecting the operating frequency f as a parameter, the actual working state and load of the compressor can be understood to determine whether it exceeds its rated load. The exhaust temperature T is positively correlated with the compressor load. A large value of T means that the compressor has a large overheating load, and vice versa. By selecting the exhaust temperature T as a parameter, the load of the compressor can be indirectly evaluated, thereby avoiding damage to the compressor.

[0051] Optionally, the shutdown request corresponding to the normal shutdown includes a manual shutdown operation by the user.

[0052] Optionally, the step of controlling the operation of the air conditioner according to the operating parameters includes: when f≤f0 and T≤T1, controlling the compressor to stop; when f≤f0 and T>T1, controlling the operating frequency of the compressor to decrease; when f>f0, controlling the operating frequency of the compressor to decrease; wherein f0 is the frequency threshold and T1 is the first temperature threshold.

[0053] In this embodiment, when f≤f0 and T≤T1, it means that the current operating frequency of the compressor and the current exhaust temperature of the compressor both meet the conditions for the compressor to be directly shut down. That is, when f≤f0 and T≤T1, the compressor is directly shut down, which has a small impact on the compressor and does not affect its performance and stability. In this case, the compressor is shut down to avoid excessive operations that increase energy consumption and reduce energy consumption.

[0054] When f≤f0 and T>T1, it means that the current operating frequency of the compressor is lower than the frequency threshold for compressor shutdown, but the current exhaust temperature of the compressor does not meet the conditions for direct compressor shutdown. In this way, if the compressor is shut down directly, it will cause a greater impact on the compressor. Therefore, when f≤f0 and T>T1, the operating frequency of the compressor is reduced to reduce the exhaust temperature of the compressor until T≤T1, and the compressor is controlled to shut down, so as to avoid a greater impact on the compressor caused by direct shutdown when the compressor load is large, thereby extending the service life of the compressor and ensuring stable operation.

[0055] When f>f0, it means that the current operating frequency of the compressor is high and the operating load is large. In this case, the compressor cannot be directly controlled to stop. The compressor frequency is controlled to be reduced to reduce the load of the compressor, thereby avoiding the large impact on the compressor caused by direct shutdown when the compressor load is large, realizing the protection of the compressor, and improving the stability of the compressor operation and the service life.

[0056] In this way, when a shutdown request is received, the current operating frequency and exhaust temperature of the compressor are obtained to determine the operating state of the compressor. According to the operating state of the compressor, it is determined whether the compressor can be controlled to shut down directly. If the operating state of the compressor is low-load operation, it can be shut down directly to reduce energy consumption. If the operating state of the compressor is high-load, the operating load of the compressor is reduced by adjusting the operating frequency of the compressor, thereby reducing the impact of high-load shutdown on the compressor and improving the stability of the compressor operation.

[0057] Furthermore, the value range of f0 is: f0>80Hz.

[0058] In this embodiment, the magnitude of f0 reflects the load of the compressor. By limiting f0 to above 80 Hz, the rated range of the compressor load can be indirectly limited, thereby ensuring that the compressor load is directly shut down within the normal limit after receiving a shutdown request. When f exceeds f0, it means that the compressor load is large during operation, and direct shutdown may affect the stable operation of the compressor. By reducing the operating frequency of the compressor to reduce the load, it is avoided that the compressor is directly shut down due to a large load and has a large impact on the compressor.

[0059] Exemplarily, specific values ​​of f0 include f0=85 Hz, 90 Hz or 95 Hz.

[0060] Furthermore, the value range of T1 is T1>95°C.

[0061] In this embodiment, a high exhaust temperature indicates a large compressor load. By limiting T1 to above 95°C, the compressor load is directly shut down within normal limits after receiving a shutdown request, and the compressor load is reduced by frequency reduction to reduce the load when the compressor load is large.

[0062] Exemplarily, specific values ​​of T1 include T1=100°C, 105°C or 110°C.

[0063] Combination Figure 2 As shown, the embodiment of the present disclosure provides another control method for stopping an air conditioner, comprising:

[0064] S210: The processor determines a shutdown type in response to a shutdown request, where the shutdown type includes a normal shutdown.

[0065] S220: When the shutdown type is normal shutdown, the processor obtains the operating frequency f and the exhaust temperature T of the compressor.

[0066] S230, the processor determines whether f is less than or equal to f0, if the judgment result is yes, it goes to S232, if the judgment result is no, it goes to S250.

[0067] S232, the processor determines whether T is less than or equal to T1, if the judgment result is yes, it goes to S240, if the judgment result is no, it goes to S250.

[0068] S240, control the compressor to stop.

[0069] S250, controlling the operating frequency of the compressor to decrease.

[0070] Wherein, f0 is the frequency threshold, T1 is the first temperature threshold, f0>80Hz, T1>95℃.

[0071] Optionally, when f≤f0 and T>T1, the step of controlling the operating frequency of the compressor to decrease includes: when f≤f0 and T>T1, controlling the operating frequency of the compressor to decrease to f1, and controlling the compressor to maintain f1 operation until t1, and controlling the compressor to stop; wherein f1 is a first preset frequency and t1 is a first preset time.

[0072] In this embodiment, when f≤f0 and T>T1, it means that the current operating frequency of the compressor is lower than the frequency threshold of the compressor shutdown, but the current exhaust temperature of the compressor is higher than the temperature threshold of the compressor shutdown. This situation does not meet the condition for the compressor to shut down directly. Therefore, when f≤f0 and T>T1, the compressor operating frequency is controlled to be reduced to f1, and after the compressor operating frequency is reduced to f1, the compressor is controlled to run at the frequency of f1 for t1 to reduce the exhaust temperature of the compressor. By controlling the compressor to shut down after the compressor runs at the frequency of f1 for t1, a large impact on the compressor caused by direct shutdown when the compressor load is large is avoided, the service life of the compressor is extended and stable operation is ensured.

[0073] Furthermore, the value range of f1 is: f1<40Hz, and the value range of t1 is: t1<30s.

[0074] In this embodiment, f1<40Hz, t1<30s is the threshold interval range to ensure that the load of the compressor is small when it stops. By limiting f1 to below 40Hz, the compressor can run at a lower frequency after frequency reduction, thereby ensuring that the impact of the compressor when it stops is small. By limiting t1 to below 30s, the running time of the compressor after frequency reduction is within a reasonable range, thereby reducing the load of the compressor and avoiding extra energy loss caused by too long running time before the compressor stops.

[0075] Exemplarily, specific values ​​of f1 include f1=35 Hz, 30 Hz or 25 Hz, and specific values ​​of t1 include t1=25 s, 20 s or 15 s.

[0076] Combination Figure 3 As shown, the embodiment of the present disclosure provides another control method for stopping an air conditioner, comprising:

[0077] S310: The processor determines a shutdown type in response to a shutdown request, where the shutdown type includes a normal shutdown.

[0078] S320: When the shutdown type is normal shutdown, the processor obtains the operating frequency f and the exhaust temperature T of the compressor.

[0079] S330, the processor determines whether f is less than or equal to f0. If the judgment result is yes, the process goes to S332. If the judgment result is no, the process goes to S350.

[0080] S332, the processor determines whether T is less than or equal to T1, if the judgment result is yes, it goes to S340, if the judgment result is no, it goes to S360.

[0081] S340, control the compressor to stop.

[0082] S350, controlling the operating frequency of the compressor to decrease.

[0083] S360, controlling the operating frequency of the compressor to decrease to f1, controlling the compressor to maintain running at f1 until t1, and controlling the compressor to stop.

[0084] Wherein, f0 is the frequency threshold, f1 is the first preset frequency, T1 is the first temperature threshold, t1 is the first preset time, f0>80Hz, f1<40Hz, T1>95℃, t1<30s.

[0085] Optionally, when f>f0, the step of controlling the operating frequency of the compressor to decrease includes: when f>f0, controlling the operating frequency of the compressor to decrease to f2, and controlling the compressor to maintain f2 operation until t2, and obtaining the exhaust temperature T again; when T≤T2, controlling the compressor to stop; when T>T2, controlling the operating frequency of the compressor to decrease to f1, and controlling the compressor to maintain f1 operation until t1, and controlling the compressor to stop; wherein f2 is the second preset frequency, t2 is the second preset time, T2 is the second temperature threshold, and f0>f2>f1.

[0086] In this embodiment, when f>f0, it means that the current operating frequency of the compressor is high and the operating load is large. In this case, the compressor cannot be directly controlled to stop. Then, the operating frequency of the compressor is controlled to be reduced to f2, and after the operating frequency of the compressor is reduced to f2, the compressor is controlled to run at the frequency of f2 for t2 to reduce the load of the compressor. After the load of the compressor is reduced, the exhaust temperature T is obtained again to determine whether the condition for direct shutdown of the compressor is met.

[0087] In the case of T≤T2, it means that the current exhaust temperature of the compressor meets the condition for the compressor to be directly shut down. That is, in the case of T≤T2, the compressor is controlled to be directly shut down, which has a small impact on the compressor and does not affect its performance and stability.

[0088] In the case of T>T2, it means that the current exhaust temperature of the compressor does not meet the conditions for the compressor to shut down directly. In this way, if the compressor is shut down directly, it will cause a greater impact on the compressor. Therefore, in the case of T>T2, the operating frequency of the compressor is reduced to f1, and after the operating frequency of the compressor is reduced to f1, the compressor is controlled to run at the frequency of f1 for t1 to reduce the exhaust temperature of the compressor. By controlling the compressor to shut down after the compressor runs at the frequency of f1 for t1, a greater impact on the compressor caused by direct shutdown when the compressor load is large is avoided, the service life of the compressor is extended and stable operation is ensured.

[0089] Furthermore, the value range of f2 is: 60 Hz≤f2≤80 Hz, and the value range of t2 is: t2<30 s.

[0090] Exemplarily, specific values ​​of f2 include f2=60 Hz, 70 Hz or 80 Hz, and specific values ​​of t2 include t2=25 s, 20 s or 15 s.

[0091] Furthermore, the value range of T2 is: T2>80℃.

[0092] In this embodiment, T2>80°C is a temperature threshold range to ensure that the load is small when the compressor is stopped. By limiting T2 to above 80°C, the compressor can continue to reduce the frequency if the exhaust temperature is still high and the load is large after reducing the frequency, thereby reducing the load when the compressor is stopped, thereby ensuring the use experience of the compressor.

[0093] Exemplarily, specific values ​​of T2 include T2=85°C, 90°C or 95°C.

[0094] Combination Figure 4 As shown, the embodiment of the present disclosure provides another control method for stopping an air conditioner, comprising:

[0095] S410: The processor determines a shutdown type in response to a shutdown request, where the shutdown type includes a normal shutdown.

[0096] S420: When the shutdown type is normal shutdown, the processor obtains the operating frequency f and the exhaust temperature T of the compressor.

[0097] S430, the processor determines whether f is less than or equal to f0, if the determination result is yes, the process proceeds to S432, if the determination result is no, the process proceeds to S450.

[0098] S432, the processor determines whether T is less than or equal to T1, if the judgment result is yes, it goes to S440, if the judgment result is no, it goes to S460.

[0099] S440, control the compressor to stop.

[0100] S450, controlling the operating frequency of the compressor to decrease to f2, and controlling the compressor to maintain operating at f2 until t2, and obtaining the exhaust gas temperature T again.

[0101] S452, the processor determines whether T is less than or equal to T2, if the judgment result is yes, it goes to S440, if the judgment result is no, it goes to S460.

[0102] S460, controlling the operating frequency of the compressor to decrease to f1, controlling the compressor to maintain running at f1 until t1, and controlling the compressor to stop.

[0103] Among them, f0 is the frequency threshold, f1 is the first preset frequency, f2 is the second preset frequency, T1 is the first temperature threshold, T2 is the second temperature threshold, t1 is the first preset time, t2 is the second preset time, f0>80Hz, f1<40Hz, 60Hz≤f2≤80Hz, and f0>f2>f1, T1>95℃, T2>80℃, t1<30s, t2<30s.

[0104] In some embodiments, the step of obtaining the operating parameters of the air conditioner corresponding to the shutdown type according to the shutdown type further includes: when the shutdown type is a fault shutdown, obtaining the exhaust pressure P of the compressor.

[0105] In this embodiment, when the shutdown type is a fault shutdown, it indicates that the shutdown request is generated due to a change in the compressor load. The compressor is controlled to operate according to the control logic of the fault shutdown by obtaining the exhaust pressure P of the compressor. The size of the exhaust pressure P directly reflects the compressor load. When the load is too large, the exhaust pressure P increases accordingly. Different from the exhaust temperature T, the exhaust pressure P reacts faster than the exhaust temperature T. By selecting the exhaust pressure P as a parameter, the operating state of the compressor can be reflected more quickly in the case of a fault shutdown, preventing the compressor from running in a fault state for too long and being damaged.

[0106] Optionally, the step of controlling the operation of the air conditioner according to the operating parameters further includes: when P>P1, controlling the compressor to stop; when P≤P1, controlling the exhaust pressure of the compressor to decrease; wherein P1 is the first pressure threshold.

[0107] In this embodiment, when P>P1, it indicates that the current exhaust pressure of the compressor is too high, and the condition for the compressor to be directly shut down is met. That is, when P>P1, the compressor is controlled to be directly shut down to prevent drastic load changes from causing damage to the compressor and other components, thereby extending the service life of the compressor and ensuring stable operation.

[0108] In the case of P≤P1, it means that the current exhaust pressure of the compressor is lower than the pressure threshold for compressor shutdown, and the conditions for direct compressor shutdown are not met. In order to prevent the compressor from shutting down due to faults as much as possible, in the case of P≤P1, the exhaust pressure of the compressor is reduced to reduce the load of the compressor, thereby enabling the compressor to continue to operate and improving the stability of compressor operation.

[0109] In this way, when a shutdown request is received, the current exhaust pressure of the compressor is obtained to determine the operating status of the compressor. According to the operating status of the compressor, determine whether the compressor can be controlled to shut down directly. In the case where the shutdown type is a fault shutdown, if the exhaust pressure of the compressor is too high, it means that the load changes drastically. In this case, it is necessary to shut down immediately to prevent damage to the compressor. If the current exhaust pressure P of the compressor is less than or equal to P1, the exhaust pressure of the compressor is controlled to decrease in order to reduce the load change of the compressor, thereby reducing the impact of the fault on the compressor, so that the compressor can continue to operate to meet the user's applicable needs and improve the user's experience.

[0110] Furthermore, the value range of P1 is: P1 ≥ 4 MPa.

[0111] In this embodiment, P1≥4MPa is the maximum range of the exhaust pressure when the compressor is running. By limiting P1 to 4MPa or above, it is ensured that the compressor will be shut down immediately when the load is too large due to a fault, thereby preventing the compressor from being damaged.

[0112] For example, the specific value of P1 includes P 1＝ 4MPa, 4.1MPa or 4.2MPa.

[0113] Combination Figure 5 As shown, the embodiment of the present disclosure provides another control method for stopping an air conditioner, comprising:

[0114] S510: The processor determines a shutdown type in response to a shutdown request, where the shutdown type includes a fault shutdown.

[0115] S520: When the shutdown type is a fault shutdown, obtain the exhaust pressure P of the compressor.

[0116] S530, the processor determines whether P is less than or equal to P1, if the determination result is yes, the process proceeds to S540, if the determination result is no, the process proceeds to S550.

[0117] S540, controlling the exhaust pressure of the compressor to decrease.

[0118] S550, controls the compressor to stop.

[0119] Wherein, P1 is the first pressure threshold, and P1≥4MPa.

[0120] Optionally, when P≤P1, the step of controlling the compressor's exhaust pressure to decrease includes: when P≤P1, adjusting the opening of the electronic expansion valve to the maximum opening, and obtaining the compressor's exhaust pressure P again; when P>P2, controlling the compressor to shut down; when P≤P2, controlling the compressor's operating frequency to decrease; wherein P2 is the second pressure threshold, and P1>P2.

[0121] In this embodiment, when P≤P1, it means that the current exhaust pressure of the compressor does not meet the direct shutdown condition. In this case, the compressor cannot be directly controlled to shut down. The exhaust pressure of the compressor is reduced by adjusting the opening of the electronic expansion valve to the maximum opening. After adjusting the opening, the exhaust pressure P is obtained again to determine whether the direct shutdown condition of the compressor is met.

[0122] In the case of P>P2, it means that the opening of the electronic expansion valve to the maximum opening is ineffective for regulating the exhaust pressure of the compressor, and the load change of the compressor cannot be reduced by adjusting the opening of the electronic expansion valve. That is, in the case of P>P2, the compressor is controlled to shut down directly to prevent the fault from causing damage to the compressor and other components.

[0123] In the case of P≤P2, it means that the opening of the electronic expansion valve to the maximum opening is effective for regulating the exhaust pressure of the compressor. In this case, the frequency of the compressor is continuously controlled to reduce the load change of the compressor, thereby enabling the compressor to continue to operate and improving the stability of the compressor operation.

[0124] Furthermore, the value range of P2 is: 3MPa≤P2<4MPa.

[0125] In this embodiment, 3MPa to 4MPa is the normal range of the exhaust pressure after the expansion valve is opened to the maximum opening in the case of fault shutdown. By limiting P2 to between 3MPa and 4MPa, it is ensured that the compressor can be shut down in time when the exhaust pressure P of the compressor is still high after adjusting the opening of the electronic expansion valve to the maximum opening.

[0126] Exemplarily, specific values ​​of P2 include P2=3.2MPa, 3.5MPa or 3.8MPa.

[0127] Combination Figure 6 As shown, the embodiment of the present disclosure provides another control method for stopping an air conditioner, comprising:

[0128] S610: The processor determines a shutdown type in response to a shutdown request, where the shutdown type includes a fault shutdown.

[0129] S620: When the shutdown type is a fault shutdown, obtain the exhaust pressure P of the compressor.

[0130] S630, the processor determines whether P is less than or equal to P1. If the determination result is yes, the process proceeds to S640. If the determination result is no, the process proceeds to S660.

[0131] S640, adjusting the opening of the electronic expansion valve to the maximum opening, and obtaining the exhaust pressure P of the compressor again.

[0132] S650, the processor determines whether P is less than or equal to P2. If the determination result is yes, the process proceeds to S670. If the determination result is no, the process proceeds to S660.

[0133] S660, controls the compressor to stop.

[0134] S670, controlling the operating frequency of the compressor to decrease.

[0135] Wherein, P1 is the first pressure threshold, P2 is the second pressure threshold, P1≥4MPa, 3MPa≤P2<4MPa, and P1>P2.

[0136] Optionally, when P≤P2, the step of controlling the operating frequency of the compressor to decrease includes: when P≤P2, controlling the operating frequency of the compressor to decrease to f1, and controlling the compressor to maintain f1 operation until t3, and obtaining the exhaust pressure P of the compressor again; when P>P3, controlling the compressor to stop; when P≤P3, controlling the compressor to operate normally; wherein t3 is the third preset time, P3 is the third pressure threshold, and P2>P3.

[0137] In this embodiment, when P≤P2, the frequency of the compressor is controlled to be reduced to f1, and after the operating frequency of the compressor is reduced to f1, the compressor is controlled to operate at the frequency of f1 for t3 to reduce the exhaust pressure of the compressor. The severity of the load change of the compressor is determined by obtaining the exhaust pressure P again, and whether the compressor can continue to operate.

[0138] In the case of P>P3, it means that the compressor frequency reduction operation is ineffective in regulating the exhaust pressure of the compressor, and the load change is still large, which does not meet the conditions for continued operation. In other words, in the case of P>P3, the compressor is controlled to shut down directly to prevent the compressor from continuing to run under fault conditions and causing damage to it.

[0139] In the case of P≤P3, it means that the compressor frequency reduction operation is effective in regulating the exhaust pressure of the compressor, the load change after frequency reduction operation is reduced, and the compressor can continue to operate. Therefore, in the case of P≤P3, the compressor is controlled to operate normally.

[0140] Furthermore, the value range of P3 is: 2MPa≤P3<3MPa.

[0141] In this embodiment, 2MPa≤P3<3MPa is the exhaust pressure range that ensures the normal operation of the compressor without being damaged by a fault. By limiting P3 to between 2MPa and 3MPa, the compressor can continue to operate when the frequency reduction operation is effective for the exhaust pressure regulation of the compressor, thereby ensuring the stability of the compressor and the system.

[0142] Exemplarily, specific values ​​of P3 include P3=2.2MPa, 2.5MPa or 2.8MPa.

[0143] Furthermore, the value range of t3 is: t3<30s.

[0144] In this embodiment, t2 is limited to less than 30s so that the running time of the compressor after the frequency is reduced to f1 is within a reasonable range, thereby preventing the compressor from being damaged due to excessive running time under the condition of drastic load changes.

[0145] Exemplarily, specific values ​​of t3 include t3=25s, 20s or 15s.

[0146] Combination Figure 7 As shown, the embodiment of the present disclosure provides another control method for stopping an air conditioner, comprising:

[0147] S710: The processor determines a shutdown type in response to a shutdown request, where the shutdown type includes a fault shutdown.

[0148] S720: When the shutdown type is a fault shutdown, obtain the exhaust pressure P of the compressor.

[0149] S730, the processor determines whether P is less than or equal to P1. If the determination result is yes, the process proceeds to S740. If the determination result is no, the process proceeds to S760.

[0150] S740, adjusting the opening of the electronic expansion valve to the maximum opening, and obtaining the exhaust pressure P of the compressor again.

[0151] S750, the processor determines whether P is less than or equal to P2. If the judgment result is yes, the process proceeds to S770. If the judgment result is no, the process proceeds to S760.

[0152] S760, controls the compressor to stop.

[0153] S770, controlling the operating frequency of the compressor to decrease to f1, and controlling the compressor to maintain running at f1 until t3, and obtaining the exhaust pressure P of the compressor again.

[0154] S780, the processor determines whether P is less than or equal to P3. If the judgment result is yes, the process proceeds to S790. If the judgment result is no, the process proceeds to S760.

[0155] S790, controls the normal operation of the compressor.

[0156] Among them, f1 is the first preset frequency, t3 is the third preset time, P1 is the first pressure threshold, P2 is the second pressure threshold, P3 is the third pressure threshold, f1<40Hz, t3<30s, P1≥4MPa, 3MPa≤P2<4MPa, 2MPa≤P3<3MPa, and P1>P2>P3.

[0157] In some embodiments, in response to a shutdown request, the step of determining a shutdown type includes: obtaining a fault code corresponding to the shutdown request according to the shutdown request; and determining, according to the fault code, that the shutdown type includes a fan fault or a water pump fault.

[0158] In this embodiment, the fault code can provide prompt information about the reason for the shutdown. Obtaining the fault code corresponding to the shutdown request according to the shutdown request can understand the specific fault type causing the shutdown and shorten the troubleshooting time. In this way, when a shutdown request is received, the fault code corresponding to the shutdown request is obtained to determine the shutdown type and then control the operation of the compressor.

[0159] Optionally, according to the shutdown type, the step of obtaining the operating parameters of the air conditioner corresponding to the shutdown type further includes: obtaining the number of occurrences n of the fan failure or the water pump failure within a preset time period.

[0160] In this embodiment, when the shutdown type is a fan failure or a water pump failure, the number of occurrences n of the fan failure or the water pump failure represents the frequency of the failure. The larger the n, the more times the failure occurs within the preset time length, and the higher the frequency. By obtaining the number of occurrences n of the fan failure or the water pump failure within the preset time length as a parameter, the severity of the failure can be reflected, and the compressor can be controlled to shut down or operate normally.

[0161] Optionally, the step of controlling the operation of the air conditioner according to the operating parameters further includes: when n≥n0, controlling the compressor to stop; when n<n0, controlling the compressor to operate normally; wherein n0 is a number threshold.

[0162] In this embodiment, when n≥n0, it means that the number of occurrences of the current fan failure or water pump failure of the compressor meets the condition for direct shutdown of the compressor. That is, when n≥n0, the compressor is controlled to shut down directly, thereby avoiding a large impact on the compressor caused by the continued operation of the compressor under the fan failure or water pump failure, thereby protecting the compressor to prevent the failure from causing damage to the compressor.

[0163] In the case of n<n0, it means that the number of occurrences of the current fan fault or water pump fault of the compressor does not meet the condition for the compressor to shut down directly. In this way, if the compressor is shut down directly, the output effect of the air conditioner will be affected. Therefore, in the case of n<n0, the compressor is controlled to operate normally, so that the number of fault occurrences is within a reasonable range, and the compressor can operate normally to meet the use requirements of the equipment.

[0164] In this way, by determining that the shutdown type is a fan failure or a water pump failure, the number of occurrences of the fan failure or the water pump failure is obtained to determine the operating state of the compressor. According to the operating state of the compressor, it is determined whether the compressor can be controlled to shut down directly. If the compressor fails frequently, it can be shut down directly to prevent damage to the compressor. If the compressor fails less frequently, the compressor is controlled to run normally, thereby improving the stability of the compressor operation.

[0165] Furthermore, the value range of n0 is: 5≥n0≥3.

[0166] In this embodiment, the size of n0 reflects the fault tolerance of the compressor and the operating system when a fault occurs. By limiting n0 to be greater than or equal to 3, the fault tolerance of the compressor and the operating system is met. At the same time, if n is only determined once, there is a certain possibility of misjudgment. By limiting n0 to perform multiple checks on the number of fault occurrences, the compressor operation can be controlled more accurately to prevent the compressor from shutting down due to system misjudgment.

[0167] Exemplarily, specific values ​​of n0 include n0=3.

[0186] Optionally, the preset amplitude has a value range of 0.8 Hz / s to 1.5 Hz / s, and specific values ​​of the preset amplitude include 0.8 Hz / s, 1 Hz / s or 1.5 Hz / s.
