Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner equipment, and in particular to an air conditioner control method and an air conditioner. Background Art

[0002] AC contactor is a widely used low-voltage control electrical appliance. Its working principle is to use the magnetic field generated when AC current passes through the coil to close the contacts of the AC contactor. AC contactor is mainly used to frequently connect and disconnect AC main circuits and large-capacity control circuits over long distances. AC contactors are widely used in air-conditioning compressor control circuits.

[0003] Once the compressor contactor (or relay) becomes stuck, the compressor will continue to run even when it is turned off. At this time, the internal and external fans are not turned on, which will cause the compressor current to increase sharply and the cylinder temperature to increase sharply, eventually triggering the compressor overload action. If the user does not notice it for a long time, the compressor will be in an abnormal operating state for a long time, and overload failure will cause abnormal faults such as terminal punchout.

[0004] With respect to the technical problem that when the compressor contactor becomes stuck, the compressor overload action is triggered by the long-term abnormal operation of the compressor, and no effective solution has been proposed so far. Summary of the invention

[0005] The main purpose of the present invention is to provide an air conditioner control method and an air conditioner to solve the problem in the prior art that when the compressor contactor is stuck, the compressor operates abnormally for a long time, triggering the compressor overload action.

[0006] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, there is provided an air conditioner control method, comprising: detecting a compressor state, the compressor state including at least a running state and a stopped state; when it is determined that the compressor state is in a stopped state within a preset time, detecting the compressor current; judging whether the compressor relay satisfies a preset fault condition based on the compressor current; when it is determined that the compressor relay satisfies the preset fault condition, controlling the air conditioner to enter a preset protection mode and generating a fault prompt message, wherein, in the preset protection mode, the compressor remains in a stopped state, the indoor fan of the air conditioner runs at a first preset gear, and the outdoor fan of the air conditioner runs at a second preset gear.

[0007] Furthermore, the preset fault condition is: within a first preset time period, the compressor state is a stop state and the compressor current is greater than or equal to a preset fault current.

[0008] Furthermore, after controlling the air conditioner to enter a preset protection mode, the method further includes: generating an alarm prompt instruction when it is determined that the compressor relay meets a preset alarm condition, the alarm prompt instruction being used to control the alarm to send out an alarm prompt message.

[0009] Furthermore, the preset alarm condition is: within the second preset time period, the compressor state is a stop state and the compressor current is greater than or equal to a preset fault current.

[0010] Furthermore, after controlling the air conditioner to enter a preset protection mode, the method also includes: detecting the compressor exhaust temperature and the compressor current; when it is determined that the compressor exhaust temperature and the compressor current meet the first judgment condition, controlling the internal fan to maintain the first preset gear operation; wherein the first judgment condition is that within a third preset time period, the compressor exhaust temperature is less than the first preset temperature value and the compressor current is less than the first preset current value.

[0011] Furthermore, after controlling the air conditioner to enter a preset protection mode, the method also includes: when it is determined that the compressor exhaust temperature and the compressor current meet the second judgment condition, controlling the internal fan to switch from the running state to the off state; wherein the second judgment condition is that within a third preset time period, the exhaust temperature is greater than or equal to the second preset temperature value, or the compressor current is greater than or equal to the second preset current value.

[0012] Furthermore, after controlling the air conditioner to enter the preset protection mode, the method further includes: when the compressor current is less than the third preset current value within a fourth preset time period, exiting the preset protection mode.

[0013] Furthermore, after exiting the preset protection mode, the method further includes: controlling the compressor to be powered on again and determining whether the compressor relay meets a preset fault condition.

[0014] Furthermore, the alarm is a buzzer.

[0015] According to another aspect of the present invention, an air conditioner is provided, and the air conditioner is controlled by the above-mentioned air conditioner control method.

[0016] The technical solution of the present invention is applied to detect the state of the compressor, which includes at least the running state and the stopping state; when it is determined that the state of the compressor is in the stopping state within the preset time, the compressor current is detected; based on the compressor current, it is determined whether the compressor relay meets the preset fault condition; when it is determined that the compressor relay meets the preset fault condition, the air conditioner is controlled to enter the preset protection mode and generate a fault prompt message, wherein, in the preset protection mode, the compressor remains in the stopping state, the inner fan of the air conditioner runs according to the first preset gear, and the outer fan of the air conditioner runs according to the second preset gear. In this solution, turning on the outer fan can dissipate heat for the compressor, and issuing a fault prompt message can remind the user to check the compressor abnormality in time. After detecting the adhesion of the compressor relay, this solution can promptly process and feedback the compressor relay adhesion fault, avoid abnormalities such as overload protection and terminal rushing out due to relay adhesion, and also avoid power loss caused by relay failure.

[0030] According to a specific embodiment of the present application, there is provided an air conditioner control method running on the above-mentioned computer terminal, such as Figure 2 As shown, the method comprises the following steps:

[0031] S21, detecting the compressor state, where the compressor state at least includes a running state and a stopped state;

[0032] S22, when it is determined that the compressor is in a stopped state within a preset time, detecting the compressor current;

[0033] Specifically, in step S22, the preset time is 3 to 10 seconds.

[0034] S23, judging whether the compressor relay meets a preset fault condition based on the compressor current;

[0035] S24, when it is determined that the compressor relay meets the preset fault condition, the air conditioner is controlled to enter the preset protection mode and generate a fault prompt message, wherein, in the preset protection mode, the compressor remains stopped, the indoor fan of the air conditioner operates according to the first preset gear, and the outdoor fan of the air conditioner operates according to the second preset gear.

[0036] Specifically, in step S24, the first preset gear is a low wind gear, and the second preset gear is a high wind gear. In addition, after the air conditioner is controlled to enter the preset protection mode, the remaining protection function modes of the air conditioner (such as exhaust temperature protection, etc.) are in a shielded state to prevent the remaining protection function modes from interfering with the operation of the preset protection mode. It should be understood that in this solution, the compressor remains in a stopped state means that the controller signal at this time is a compressor stop operation signal.

[0037] The technical solution of this embodiment is applied to detect the state of the compressor, which includes at least the running state and the stopped state; when it is determined that the state of the compressor is in the stopped state within the preset time, the compressor current is detected; based on the compressor current, it is determined whether the compressor relay meets the preset fault condition; when it is determined that the compressor relay meets the preset fault condition, the air conditioner is controlled to enter the preset protection mode and generate a fault prompt message, wherein, in the preset protection mode, the compressor remains in the stopped state, the inner fan of the air conditioner runs according to the first preset gear, and the outer fan of the air conditioner runs according to the second preset gear. In this solution, turning on the outer fan can dissipate heat for the compressor, and issuing a fault prompt message can remind the user to check the compressor abnormality in time. After detecting the adhesion of the compressor relay, this solution can promptly process and feedback the compressor relay adhesion fault, avoid abnormalities such as overload protection and terminal rushing out due to relay adhesion, and also avoid power loss caused by relay failure.

[0038] Optionally, in step S23, the preset fault condition is: within a first preset time period, the compressor state is a stop state and the compressor current is greater than or equal to a preset fault current.

[0039] Through step S23, when it is determined that the compressor is in a stopped state and the compressor current is greater than or equal to the preset fault current, it can be determined that the compressor relay is stuck. At this time, the air conditioner is controlled to enter the preset protection mode and generate a fault prompt message, which can effectively adjust the internal heat dissipation of the compressor, avoid compressor overload, and promptly remind the user to repair the compressor relay. Preferably, the first preset time length is 3 to 10 seconds.

[0040] Optionally, after controlling the air conditioner to enter a preset protection mode, the method further includes:

[0041] S25, when it is determined that the compressor relay meets the preset alarm condition, an alarm prompt instruction is generated, and the alarm prompt instruction is used to control the alarm to send out an alarm prompt information.

[0042] Through step S25, the user is promptly notified to repair the compressor relay, thereby solving the problem of the compressor relay sticking, which causes the compressor to continue to run and increase power consumption.

[0043] Optionally, in step S25, the preset alarm condition is: within a second preset time period, the compressor state is a stop state and the compressor current is greater than or equal to a preset fault current.

[0044] By setting a preset alarm condition, that is, within the second preset time after the air conditioner enters the preset protection mode, when the compressor current is greater than or equal to the preset fault current, an alarm prompt message is issued to promptly remind the user to inspect the compressor relay, reduce the power consumption of the air conditioner itself, and avoid compressor overload. Preferably, the second preset time is greater than the first preset time, and the second preset time can be 10 minutes.

[0045] Optionally, after controlling the air conditioner to enter a preset protection mode, the method further includes:

[0046] S261, detecting the compressor exhaust temperature and the compressor current;

[0047] S262, when it is determined that the compressor exhaust temperature and the compressor current meet the first judgment condition, control the internal fan to maintain the first preset gear operation, wherein the first judgment condition is that within a third preset time period, the compressor exhaust temperature is less than the first preset temperature value and the compressor current is less than the first preset current value.

[0048] Through step S261 and step S262, when it is determined that the compressor exhaust temperature and the compressor current are small, the inner fan is controlled to maintain the first preset gear to balance the system pressure, avoiding the icing problem that is easy to occur when the outer fan is running and the inner fan is turned off, so as to achieve better heat dissipation effect. Preferably, the first preset current value is greater than the preset fault current, and the third preset time length can be 3 to 10 seconds.

[0049] Optionally, after controlling the air conditioner to enter a preset protection mode, the method also includes: S263, when it is determined that the compressor exhaust temperature and the compressor current meet the second judgment condition, controlling the internal fan to switch from the running state to the off state, wherein the second judgment condition is that within a third preset time period, the exhaust temperature is greater than or equal to the second preset temperature value, or the compressor current is greater than or equal to the second preset current value.

[0050] Through step S263, when the exhaust temperature of the compressor and the compressor current are relatively high, the internal fan is controlled to switch from the running state to the off state to reduce the load of the whole machine, which can avoid the problem of system abnormality caused by excessive load, avoid further increase in temperature, and facilitate heat dissipation. Preferably, the second preset temperature value is greater than the first preset temperature value, and the second preset current value is greater than the first preset current value.

[0051] Optionally, after controlling the air conditioner to enter the preset protection mode, the method further includes: S27, exiting the preset protection mode when the compressor current is less than the third preset current value within a fourth preset time period.

[0052] Through step S27, when the compressor current is less than the third preset current value, it indicates that the compressor is not at risk of overload at this time, and the preset protection mode is exited at this time, which can reduce the power loss of the air conditioner. Preferably, the fourth preset time length is greater than the second preset time length, the third preset current value is less than the preset fault current, and the fourth preset time length can be 2 hours.

[0053] Optionally, after exiting the preset protection mode, the method further includes: S28, controlling the compressor to power on again and determining whether the compressor relay meets a preset fault condition.

[0054] Through step S28, after exiting the preset protection mode, the compressor is controlled to be powered on again and it is determined whether the compressor relay meets the preset fault condition, which can further ensure that the compressor current is within the normal range and reduce the risk of compressor overload.

[0055] Optionally, the alarm is a buzzer. The buzzer alarm can be used to remind the user to repair the compressor in time. It should be noted that the alarm can also use an indicator light, voice prompt and other alarm methods.

[0056] Figure 3Another embodiment of the air conditioner control method of the present application is provided. Correspondingly, in the foregoing embodiment, t1 is the first preset duration, t2 is the second preset duration, t3 is the third preset duration, t4 is the fourth preset duration, T exhaust 1 is the first preset temperature value, T exhaust 2 is the second preset temperature value, I0 is the preset fault current, I1 is the first preset current value, I2 is the second preset current value, and I3 is the third preset current value.

[0057] Specifically, as Figure 3 shown, the method includes the following steps:

[0058] 1. After the controller detects that the compressor has stopped for t0, start detecting the compressor current I. When it continuously detects the compressor stop state for t1 and any-phase compressor current ≥ I0, execute the preset protection mode. At this time, control the compressor to remain in the stopped state (this is a controller signal. Actually, when the relay is stuck, the compressor is in the running state), turn on the indoor fan (the indoor fan is in the low wind gear), the outdoor fan (the outdoor fan is in the high wind gear), and it is not affected by the ambient temperature and the set temperature, display the fault code "LL", and shield other protections.

[0059] 2. If the fault still does not disappear after continuous t2 minutes, the buzzer will sound an alarm.

[0060] 3. During the fault protection period, if it continuously detects that the compressor current ≥ I2 for t3, or continuously detects that the exhaust temperature ≥ T exhaust 2 for t3, then turn off the indoor fan (reduce the load); if it continuously detects that the compressor current < I1 for t3 and continuously detects that the exhaust temperature < T exhaust 1 for t3, then turn on the indoor fan.

[0061] 4. During the fault protection period, if it continuously detects that the compressor current ≤ I3 for t4 hours, then exit the protection mode; or after power-on again, clear the fault and start detecting again.

[0062] It should be noted that during the preset protection mode, if the load is accidentally overloaded and the compressor overloads, at this time the compressor current drops to 0. To avoid exiting the preset protection mode in this case, extend t4, for example, extend it to 2h. Since the compressor overload action and recovery cycle are generally within 1 hour, extending t4 can prevent the air conditioner from exiting the preset protection mode due to load overload.

[0063] In this embodiment, the values of each parameter are shown in Table 1.

[0064] Table 1

[0065]

[0066] It should be noted that according to different cooling capacity segments of the air conditioner, the compressor power and current are different, and the above parameter values can be adjusted according to actual needs.

[0067] When the air conditioner control method in the above embodiment is used to control the air conditioner, current detection is used to determine whether the compressor relay is stuck. When it is determined that sticking occurs, the air conditioner is controlled to enter a preset protection mode, and components such as the internal fan and the external fan perform corresponding actions to generate fault prompt information. The compressor relay sticking failure can be handled and fed back in a timely and effective manner to avoid overload protection or even terminal punching out due to relay sticking. The after-sales problems caused by relay failure can be solved, the after-sales failure rate can be reduced, and the reliability of the entire machine can be improved. At the same time, the power loss caused by relay failure can also be avoided.

[0068] Table 2 and Table 3 are test data of an air conditioner test performed by applying the air conditioner control method in the above embodiment.

[0069] Among them, the serial number columns in Table 3 correspond to the serial number columns in Table 2. The test conclusions are as follows:

[0070] 1. When the compressor relay is normal, the system operates normally and no false protection occurs after 3 starts and stops;

[0071] 2. When the compressor contactor is stuck, the preset protection mode is turned on. About 10 seconds after the compressor is shut down, the internal fan, external fan and air guide mechanism start running, and the display board reports "LL" fault. After the system continues to run for 10 minutes, the buzzer sounds an alarm.

[0072] 3. The test shows that under different working conditions and voltages, the compressor cylinder temperature is normal, the system pressure is normal, and the system current is within the normal range;

[0073] 4. The protection function in this solution can protect the compressor and air conditioner, and promptly and effectively handle and feedback the compressor relay adhesion failure, avoiding overload protection or even terminal punchout due to relay adhesion. It can solve after-sales problems caused by relay failure, reduce after-sales failure rate, improve the reliability of the whole machine, and also avoid power loss caused by relay failure.
