Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

An air conditioner fast inspection method, an air conditioner fast inspection apparatus, a computer-readable storage medium, and an air conditioner according to embodiments of the present invention are described below with reference to the accompanying drawings.

Fig. 1 is a flowchart of an air conditioner quick check method according to an embodiment of the present invention.

As shown in fig. 1, the present invention provides a fast inspection method for an air conditioner, which comprises the following steps:

and S10, when the air conditioner is started in a high-frequency starting mode, acquiring the current state parameters of the air conditioner, and acquiring the state parameters recorded when the air conditioner is stopped at the last time.

Specifically, in this embodiment, the status parameters of the air conditioner may include the temperature of the first evaporator and the temperature of the first condenser in the air conditioner, and it is understood that the status parameters may be recorded in real time during the operation of the air conditioner, and the frequency of the real-time recording may be set according to the actual requirements of the user, or the operation condition of the air conditioner may be set, optionally, the temperature of the evaporator and the temperature of the condenser in the air conditioner may be recorded every half minute, or the temperature of the evaporator and the temperature of the condenser in the air conditioner may be recorded every 15 seconds, where the frequency of recording the status parameters is not limited. Of course, it should be noted that, in this embodiment, regardless of the recording frequency of the status parameters, when the air conditioner is stopped to operate, the status parameters of the air conditioner in the previous second of the stop may be recorded, so as to ensure that the temperature of the evaporator and the temperature of the condenser can be recorded when the air conditioner is stopped.

The specific way of acquiring the temperature data may be to acquire the temperature data by setting a sensor or by capturing relevant data by a controller of the air conditioner and then performing an operation. For example, the temperature sensors may be provided to detect and acquire the temperatures in the evaporator and the condenser of the air conditioner. It should be noted that, in this embodiment, a specific acquiring manner of the two temperature data, i.e., the temperature of the evaporator and the temperature of the condenser in the air conditioner, may not be limited, and the specific acquiring manner of the temperatures may be adaptively set according to an actual application scenario.

According to the embodiment, the temperature of the evaporator and the temperature of the condenser of the air conditioner can be accurately recorded in real time before the air conditioner is stopped to serve as parameters of the stop state of the air conditioner, then when the air conditioner is restarted in a high-frequency starting mode, the temperature of the evaporator and the temperature of the condenser which are recorded when the air conditioner is stopped last time can be used as state parameters of the air conditioner when the air conditioner is stopped last time, and then the temperature of the first evaporator and the temperature of the first condenser which are acquired after the air conditioner is restarted are recorded in real time.

It should be noted that, in this embodiment, the temperature of the evaporator and the temperature of the condenser may be both stored in a storage medium in the air conditioner, and the temperatures of the evaporator and the condenser may be stored in a stack manner, so as to ensure real-time performance and accuracy of currently recorded data.

And S20, comparing the current state parameter of the air conditioner with the state parameter recorded when the air conditioner is stopped last time, and obtaining the comparison result.

Specifically, after the air conditioner is restarted and the current state parameter of the air conditioner and the state parameter recorded at the last shutdown of the air conditioner are obtained, the two state parameters may be compared, where the temperature of the current first evaporator of the air conditioner may be compared with the temperature of the evaporator at the last shutdown of the air conditioner, and the temperature of the current first condenser of the air conditioner may be compared with the temperature of the condenser at the last shutdown of the air conditioner. When the temperature difference between the air conditioner and the air conditioner is small, it can be determined that the time from the previous shutdown is long when the air conditioner is started at the high frequency, so that the air conditioner can be started in a high-frequency starting mode.

And S30, judging whether the comparison result meets the condition of high-frequency starting of the air conditioner, and starting the air conditioner in a high-frequency starting mode if the comparison result meets the condition.

Specifically, in this embodiment, a preset temperature threshold may be set to determine whether the current state parameter of the air conditioner meets the condition of high-frequency starting or not, and if so, it is indicated that the high-frequency starting may be performed in the current state of the air conditioner, and the error determination may be avoided when the abnormality detection is performed after the air conditioner completes the high-frequency starting by the worker.

In this embodiment, the determining whether the air conditioner satisfies the condition of high frequency starting may include: whether the difference value obtained by subtracting the current first evaporator temperature of the air conditioner from the evaporator temperature corresponding to the air conditioner during the last shutdown is smaller than a first preset temperature threshold value or not is judged; and meanwhile, whether the difference value obtained by subtracting the temperature of the condenser corresponding to the air conditioner during the last shutdown from the current temperature of the first condenser of the air conditioner is smaller than a second preset temperature threshold value or not is judged. That is to say, in this embodiment, when a difference obtained by subtracting the current temperature of the first evaporator of the air conditioner from the current temperature of the first evaporator of the air conditioner when the air conditioner is stopped for the last time is smaller than a first preset temperature threshold, and meanwhile, when a difference obtained by subtracting the current temperature of the first condenser of the air conditioner from the current temperature of the first condenser of the air conditioner when the air conditioner is stopped for the last time is smaller than a second preset temperature threshold, it indicates that the current air conditioner meets a high-frequency starting condition, and the air conditioner can be started in a high-frequency starting manner.

Moreover, it can be understood that if the air conditioner is started in a high-frequency starting mode under the condition that the high-frequency starting is met, the air conditioner can be considered to enter a high-frequency starting mode in the next starting, so that a worker can normally judge the abnormality of the air conditioner without generating misjudgment. It should be noted that if the air conditioner is not started in a high-frequency starting manner, but is started at the time of ordinary starting, and at this time, when the worker normally performs an abnormality determination on the air conditioner, an erroneous determination may be generated, which may further affect the maintenance of the air conditioner and the production efficiency of the production line.

And S40, if the comparison result does not meet the condition of high-frequency starting of the air conditioner, acquiring the temperature of the indoor environment, determining the target frequency of the compressor according to the temperature of the indoor environment, and controlling the air conditioner again to start at high frequency according to the determined target frequency of the compressor.

Specifically, since the condition for determining whether the air conditioner satisfies the high-frequency start in this embodiment includes: whether the difference value obtained by subtracting the current first evaporator temperature of the air conditioner from the evaporator temperature corresponding to the air conditioner during the last shutdown is smaller than a first preset temperature threshold value or not is judged; and meanwhile, whether the difference value obtained by subtracting the temperature of the condenser corresponding to the air conditioner during the last shutdown from the current temperature of the first condenser of the air conditioner is smaller than a second preset temperature threshold value or not is judged. Therefore, in this embodiment, when a difference obtained by subtracting the current temperature of the first evaporator of the air conditioner from the current temperature of the first condenser of the air conditioner at the time of the last shutdown is not less than a first preset temperature threshold, or a difference obtained by subtracting the current temperature of the first condenser of the air conditioner from the current temperature of the first condenser of the air conditioner at the time of the last shutdown is not less than a second preset temperature threshold, it indicates that the current air conditioner does not satisfy the high-frequency startup condition.

When the current state of the air conditioner does not meet the condition of high-frequency starting, the temperature of the indoor environment where the air conditioner is located can be further obtained, then the target frequency corresponding to the compressor of the air conditioner is determined according to the temperature of the indoor environment, and then the air conditioner is controlled to be started at high frequency according to the target frequency.

It should be noted that, in the above embodiment, in the process of performing high-frequency startup again after high-frequency startup failure and shutdown of the air conditioner, instead of directly adopting a normal startup manner, the air conditioner is directly controlled to perform high-frequency startup when a comparison result meets a condition of high-frequency startup by judging a difference between a current state parameter of the air conditioner and a state parameter of the air conditioner during previous shutdown, and then comparing and judging the difference, and if the comparison result does not meet the condition of high-frequency startup, a target frequency of the compressor is determined according to a temperature of an indoor environment, and the air conditioner is controlled to perform high-frequency startup according to the target frequency. That is to say, this application can carry out the high frequency after the high frequency starts the failure and start for the second time, rather than directly get into ordinary starting mode, and then can reach the target state of air conditioner sooner, and then can effectively avoid producing artificial erroneous judgement when carrying out the anomaly detection to the air conditioner.

In addition, it should be further explained that, in the present invention, the system of the air conditioner can automatically select whether to start the air conditioner in a high frequency starting manner, that is, whether to perform the second high frequency starting, so as to further improve the control precision and the control effect, so that the air conditioner circulation system is easier to start and has smaller impact force.

In some embodiments of the present invention, as shown in fig. 2, controlling the air conditioner again for high frequency starting according to the determined target frequency of the compressor may include the steps of:

s201, performing high-frequency starting control on the compressor according to the determined target frequency of the compressor, and acquiring the temperature of a second evaporator and the temperature of a second condenser in the air conditioner.

Specifically, after the target frequency of the compressor is determined by the temperature of the indoor environment, the target frequency can be used to perform high-frequency start control on the air conditioner, and during the control, the temperature of the evaporator and the temperature of the condenser in the air conditioner can be obtained in real time and recorded as the temperature of the second evaporator and the temperature of the second condenser. The specific manner of acquiring the temperature of the second evaporator and the temperature of the second condenser may be to acquire the temperatures by setting a sensor or capturing related data by a controller of the air conditioner and then performing an operation. For example, the temperature sensors may be provided to detect and acquire the temperatures in the evaporator and the condenser of the air conditioner. It should be noted that, in this embodiment, a specific acquiring manner of the two temperature data, i.e., the temperature of the evaporator and the temperature of the condenser in the air conditioner, may not be limited, and the specific acquiring manner of the temperatures may be adaptively set according to an actual application scenario.

S202, if the difference value obtained by subtracting the temperature of the second evaporator from the temperature of the evaporator when the air conditioner is stopped last time is smaller than a first preset temperature threshold value, and the difference value obtained by subtracting the temperature of the condenser when the air conditioner is stopped last time from the temperature of the second condenser is smaller than a second preset temperature threshold value, an evaporator side fan and a condenser side fan of the air conditioner are started simultaneously.

Specifically, after the temperature of the second evaporator and the temperature of the second condenser of the air conditioner are obtained, the temperature of the evaporator and the temperature of the condenser of the air conditioner at the last shutdown can be called from the memory, and then whether a difference obtained by subtracting the current temperature of the second evaporator of the air conditioner from the temperature of the evaporator corresponding to the air conditioner at the last shutdown is smaller than a first preset temperature threshold value or not is judged; meanwhile, whether the difference value obtained by subtracting the temperature of the condenser corresponding to the air conditioner in the last shutdown from the current temperature of the second condenser of the air conditioner is smaller than a second preset temperature threshold value or not is judged. And when the difference obtained by subtracting the temperature of the current second evaporator of the air conditioner from the temperature of the evaporator corresponding to the air conditioner in the last shutdown is smaller than the first preset temperature threshold, and meanwhile, when the difference obtained by subtracting the temperature of the condenser corresponding to the air conditioner in the last shutdown from the temperature of the current second condenser of the air conditioner is smaller than the second preset temperature threshold, the evaporator side fan and the condenser side fan in the air conditioner can be started. It should be noted that the evaporator side fan and the condenser side fan in the air conditioner are controlled to be started at the same time, and the evaporator side fan and the condenser side fan can be controlled to be started quickly and operated at the target rotation speed.

In this embodiment, after the evaporator side fan and the condenser side fan are controlled to operate at the target rotation speed for the preset time, it may indicate that the second high-frequency starting mode is completed, and the air conditioner system is further controlled to operate normally.

In some embodiments of the present invention, controlling the air conditioner again for high frequency starting according to the determined target frequency of the compressor may include the steps of: s201, performing high-frequency starting control on the compressor according to the determined target frequency of the compressor, and acquiring the temperature of a second evaporator and the temperature of a second condenser in the air conditioner. S203, if the difference value obtained by subtracting the temperature of the second evaporator from the temperature of the evaporator when the air conditioner is stopped last time is larger than or equal to a first preset temperature threshold value, and the difference value obtained by subtracting the temperature of the condenser when the air conditioner is stopped last time from the temperature of the second condenser is larger than or equal to a second preset temperature threshold value, controlling the air conditioner compressor to start at high frequency.

Specifically, as shown in fig. 3, after step S201 is executed, the high-frequency start control is performed on the compressor according to the determined target frequency of the compressor, and the temperature of the second evaporator and the temperature of the second condenser in the air conditioner are simultaneously obtained. Then, whether the difference value obtained by subtracting the current second evaporator temperature of the air conditioner from the evaporator temperature corresponding to the air conditioner during the last shutdown is smaller than a first preset temperature threshold value or not can be judged; meanwhile, whether the difference value obtained by subtracting the temperature of the condenser corresponding to the air conditioner in the last shutdown from the current temperature of the second condenser of the air conditioner is smaller than a second preset temperature threshold value or not is judged. And when the difference obtained by subtracting the current second evaporator temperature of the air conditioner from the current evaporator temperature of the air conditioner at the last shutdown is greater than or equal to the first preset temperature threshold, or the difference obtained by subtracting the current condenser temperature of the air conditioner at the last shutdown from the current second condenser temperature of the air conditioner is greater than or equal to the second preset temperature threshold, the control unit may return to control the compressor to perform the high-frequency startup until the condition described in step S202 in the above embodiment is satisfied.

In one embodiment of the present invention, as shown in fig. 4, the temperature T2 of the evaporator coil and the temperature T3 of the condenser coil of the air conditioner are detected in real time, and the temperature T2 'of the evaporator coil and the temperature T3' of the condenser coil of the air conditioner before the air conditioner is shut down are recorded. When the user switches on the high-frequency starting mode, the temperature T2 of the evaporating coil and the temperature T3 of the condensing coil are detected in real time, and the detected temperatures are compared with the temperature T2 'of the evaporating coil and the temperature T3' of the condensing coil.

If the absolute value of T2 '-T2 is less than Ta and the absolute value of T3-T3' is less than Tb, namely the system parameters and the shutdown state parameters at the moment are very close to each other, the system is judged to meet the high-frequency starting condition, the high-frequency starting mode is normally started, and the system is quickly started according to the set frequency and the set frequency increasing rate. Otherwise, judging that the system does not meet the high-frequency starting condition, starting a second high-frequency starting mode, detecting the temperature T4 of the indoor environment, determining the target frequency of high-frequency starting according to the temperature T4 of the indoor environment, and controlling the high-frequency starting of the compressor. And detecting the temperature T2 of the evaporation coil and the temperature T3 of the condensation coil in real time, comparing the temperature with the temperature T2 ' of the evaporation coil and the temperature T3 ' of the condensation coil, judging that the system reaches state parameters when the system is stopped when the T2 ' -T2| < Ta and the T3-T3 | < Tb, controlling the side fan of the evaporator and the evaporator of the condenser to be started quickly at the same time, operating according to the target rotating speed, and completing a second high-frequency starting mode after the operation is set for a long time, wherein the control system operates normally. If the judgment condition is not met, returning to detect the temperature T4 of the indoor environment again, determining the target frequency of high-frequency starting according to the temperature T4 of the indoor environment, and then controlling the high-frequency starting of the compressor. Wherein, Ta is the first predetermined temperature threshold value, Tb is the second predetermined temperature threshold value.

When the air conditioner is abnormally stopped and needs to be started again at high frequency, the mode of starting the fan after the press is started firstly is adopted, so that the high-low pressure of the system is quickly increased, the high-low pressure difference before the air conditioner is stopped is achieved in the shortest time, the time interval of the high-frequency starting again is shortened, and the production efficiency of a production line is improved.

In another embodiment of the present invention, as shown in fig. 5, controlling the air conditioner again for high frequency starting according to the determined target frequency of the compressor may include the steps of:

s501, opening of a throttling element in the air conditioner is adjusted to be maximum, and an evaporator side fan and a condenser side fan in the air conditioner are started at the same time.

Specifically, after the air conditioner system does not meet the high-frequency starting condition, the air conditioner is controlled to start the high-frequency starting mode again, and more specifically, the opening degree of a throttling element in the air conditioner is firstly adjusted to be maximum, namely, the opening degree of an electronic expansion valve in the air conditioner is controlled to be maximum, so that the high-pressure and low-pressure of the system are discharged, and the high-pressure and low-pressure in the system are in an equilibrium state as soon as possible. The evaporator side fan and the condenser side fan in the air conditioner are controlled to be started simultaneously, and the evaporator side fan and the condenser side fan in the air conditioner can be controlled to be started quickly and operate according to a target rotating speed. The evaporator side fan and the condenser fan are controlled to be started quickly at the same time, and the two heat exchangers are cooled quickly so as to reach the judgment condition as soon as possible

And S502, acquiring the temperature of a second evaporator and the temperature of a second condenser in the air conditioner.

After the control of the throttling element and the indoor and outdoor fans in step S501 is completed, the temperatures of the evaporator and the condenser in the air conditioner can be detected, in this embodiment, the temperatures of the evaporator coil and the condenser coil are obtained through the temperature sensors, so as to obtain the temperature of the second evaporator and the temperature of the second condenser. It should be noted that, the specific manner of acquiring the temperature of the second evaporator and the temperature of the second condenser may be to acquire the temperatures by setting a sensor or by capturing relevant data by a controller of the air conditioner and then performing an operation. For example, the temperature sensors may be provided to detect and acquire the temperatures in the evaporator and the condenser of the air conditioner. It should be noted that, in this embodiment, a specific acquiring manner of the two temperature data, i.e., the temperature of the evaporator and the temperature of the condenser in the air conditioner, may not be limited, and the specific acquiring manner of the temperatures may be adaptively set according to an actual application scenario.

S503, if the difference value obtained by subtracting the temperature of the second evaporator from the temperature of the evaporator when the air conditioner is stopped last time is smaller than a third preset temperature threshold value, and the difference value obtained by subtracting the temperature of the condenser when the air conditioner is stopped last time from the temperature of the second condenser is smaller than a fourth preset temperature threshold value, controlling the compressor to start at high frequency according to the target frequency of the compressor.

Specifically, after the temperature of the second evaporator and the temperature of the second condenser of the air conditioner are obtained, the temperature of the evaporator and the temperature of the condenser of the air conditioner at the last shutdown can be called from the memory, and then whether a difference obtained by subtracting the current temperature of the second evaporator of the air conditioner from the temperature of the evaporator corresponding to the air conditioner at the last shutdown is smaller than a third preset temperature threshold value or not is judged; meanwhile, whether the difference value obtained by subtracting the temperature of the condenser corresponding to the air conditioner in the last shutdown from the current temperature of the second condenser of the air conditioner is smaller than a fourth preset temperature threshold value or not is judged. And when the difference obtained by subtracting the temperature of the second evaporator corresponding to the air conditioner from the temperature of the second condenser corresponding to the air conditioner during the last shutdown is smaller than a third preset temperature threshold value, and meanwhile, when the difference obtained by subtracting the temperature of the condenser corresponding to the air conditioner during the last shutdown from the temperature of the second condenser corresponding to the air conditioner during the last shutdown is smaller than a fourth preset temperature threshold value, the high-frequency starting control can be carried out on the compression according to the target frequency of the compressor.

In some embodiments of the present invention, controlling the air conditioner again for high frequency starting according to the determined target frequency of the compressor may include the steps of: s501, opening of a throttling element in the air conditioner is adjusted to be maximum, and an evaporator side fan and a condenser side fan in the air conditioner are started at the same time. And S502, acquiring the temperature of a second evaporator and the temperature of a second condenser in the air conditioner.

If the judgment condition is not met, the electronic expansion valve is returned to control the opening degree of the electronic expansion valve to be adjusted to the maximum again so as to relieve the pressure of the high pressure and the low pressure of the system, and meanwhile, the evaporator side fan and the condenser side fan are quickly started to quickly cool the evaporator and the condenser. Wherein Ta is a first preset temperature threshold, Tb is a second preset temperature threshold, Tc is a third preset temperature threshold, and Td is a fourth preset temperature threshold.
