Fig. 1 is a schematic method diagram of an embodiment of an air conditioner control method provided by the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the control method includes at least step S110 and step S130.
And step S110, after the air conditioner is started, when the indoor environment temperature is detected to meet a first preset condition, controlling the compressor to stop, and accumulating the stop times.
The first preset condition specifically includes: when the air conditioner operates in a refrigerating mode, the difference value delta t between the indoor environment temperature and the set temperature is smaller than or equal to a first preset temperature value delta t 1; during heating operation, the difference value delta t between the set temperature and the indoor environment temperature is smaller than or equal to a first preset temperature value delta t 1. The first preset temperature value delta t1 is less than or equal to 0, namely delta t1 is less than or equal to 0.
Specifically, after the air conditioner is started, the target frequency F of the air conditioner operation interval is adopted0Operating to make the indoor environment temperature tIndoor useQuickly reaches the set temperature tIs provided with. When Δ t is equal to or less than Δ t1 (when cooling, Δ t is equal to t)Indoor use-tIs provided withWhen heating, Δ t is tIs provided with-tIndoor use) The compressor is stopped, discomfort caused by too much overshoot is prevented, and the stop times are accumulated; otherwise, the current state is kept running.
And step S120, after the compressor is controlled to stop, when the indoor environment temperature is detected to meet a second preset condition, controlling the compressor to restart to operate.
The second preset condition specifically includes: when the air conditioner operates in a refrigerating mode, the difference value delta t between the indoor environment temperature and the set temperature is larger than or equal to a second preset temperature value delta t 2; during heating operation, the difference value delta t between the set temperature and the indoor environment temperature is greater than or equal to a second preset temperature value delta t 2. Namely, when the condition that the delta t is more than or equal to the delta t2 is met, the compressor is restarted to continue the cooling or heating operation; otherwise, the shutdown state is continuously maintained. The first preset temperature value is less than or equal to the second preset temperature value, namely delta t1 is less than or equal to delta t 2. The second preset temperature value delta t2 is greater than or equal to 0, namely delta t2 is greater than or equal to 0.
And step S130, determining a target frequency of restarting operation of the compressor after the Nth shutdown according to the operation time from restarting after the N-1 th shutdown to stopping for the Nth shutdown.
That is, the steps S110 to S120 are repeatedly performed until the compressor is stopped for the nth time (i.e., the number of times of stopping the compressor reaches N times), and the target frequency of the compressor restarting operation after the nth stop (i.e., the restarting operation when the second preset condition is satisfied) is determined according to the operation time T from the restart after the N-1 th stop to the nth stop. I.e. the running time when the compressor is restarted after the last (N-1) stop, when the compressor is stopped for the nth time.
If the running time is less than or equal to a first preset time T1, determining that the target frequency of the next time when the compressor restarts to run is the difference between the current target frequency and a first preset frequency correction value; if the running time is greater than a first preset time T1 and less than or equal to a second preset time T2, determining that the target frequency of the next time when the compressor restarts to run is the difference between the current target frequency and a second preset frequency correction value; and if the running time is greater than a second preset time T2, determining that the target frequency of the next time when the compressor restarts to run is the difference between the current target frequency and a third preset frequency correction value.
For example, the first predetermined frequency correction value is FAThe second predetermined frequency correction value is FBThe third preset frequency correction value is FCAnd F isA＞FB＞FCThe current target frequency is FN-1If the N-th shutdown is performed within the time T ≦ T1, the target frequency at the time of restart is FN＝FN-1-FA(ii) a The air conditioner is stopped, so that it is considered that the cooling capacity or heating capacity required for the room is not so much, and the target frequency at the next time of starting is reduced accordingly. When the N-th shutdown occurs within the time T1 < T ≦ T2, the target frequency F is used for restartingN＝FN-1-FBRunning; if the Nth shutdown occurs when T > T2, the target frequency F is used for restartingN＝FN-1-FCAnd (5) operating.
Optionally, the value range of the first preset frequency correction value, the second preset frequency correction value and/or the third preset frequency correction value includes 1Hz to 10 Hz; the first preset frequency correction value is larger than the second preset frequency correction value and is larger than the third preset frequency correction value.
Optionally, the control method further includes: when the compressor is stopped for the Nth time (in the process of stopping for the Nth time), if the set temperature of the air conditioner changes, whether the set temperature before the change and the set temperature after the change meet a third preset condition is judged; and if the set temperature before the change and the set temperature after the change do not meet the third preset condition, controlling the compressor to operate according to the initial target frequency, and resetting the accumulated shutdown times. I.e. to resume execution of the preceding steps. And if the set temperature before the change and the set temperature after the change meet the third preset condition, determining the target frequency of restarting operation of the compressor after the Nth shutdown according to the operation time from restarting after the Nth-1 th shutdown to stopping for the Nth shutdown when the compressor is stopped for the Nth shutdown.
The third preset condition includes: when the refrigerating operation is carried out, the difference between the set temperature before the change and the set temperature after the change is less than or equal to a third preset temperature value; when the heating operation is performed, the difference between the set temperature after the change and the set temperature before the change is less than or equal to a third preset temperature value.
Specifically, if the air conditioner is not shut down after being turned on and the set temperature t is not changed, the air conditioner is kept running at the current running frequency. If the temperature t is set in the Nth shutdown process of the compressorIs provided withThe set temperature before the change is recorded as t1 is providedAfter the change, the set temperature is tLet 2Noting the difference before and after the change as DeltatIs provided with(refrigeration Deltat)Is provided with＝t1 is provided-tLet 2Heating Δ tIs provided with＝tLet 2-t1 is provided) And the third preset temperature value is 0 (deg.C). When Δ t is reachedIs provided withIf > 0, the number of stops N is cleared and the operation is carried out at the initial frequency F0, at Δ tIs provided withWhen the frequency is less than or equal to 0, executing the step S130, and determining the target frequency of restarting operation of the compressor after the Nth shutdown according to the operation time from restarting after the Nth-1 th shutdown to stopping for the Nth shutdown, namely when the compressor stops for the Nth time, the set temperature is changed, and the next startup frequency is FN-1。
Optionally, after the compressor is restarted after meeting a second preset condition after being stopped every time and when the compressor runs for a third preset time, judging whether the indoor environment temperature meets a fourth preset condition; and if the indoor environment temperature meets the fourth preset condition, correcting the current target frequency.
The fourth preset condition specifically includes: when in refrigerating operation, the difference delta t between the indoor environment temperature and the set temperature is more than or equal to 0; and during heating operation, the difference value delta t between the set temperature and the indoor environment temperature is less than or equal to 0. Optionally, when it is determined that the fifth preset time of the indoor environment temperature continuously satisfies the fourth preset condition, the current target frequency is corrected.
Specifically, the corrected target frequency is determined according to the following formula based on the difference Δ t between the indoor ambient temperature and the set temperature during the cooling operation or the difference Δ t between the set temperature and the indoor ambient temperature during the heating operation.
FN＝FN+D*Δt
Wherein, FND is a correction coefficient for the current target frequency, and can be obtained through experiments.
In order to avoid that the target frequency is corrected when the temperature cannot reach the temperature set by the user after the previous shutdown and startup, the value of the correction coefficient D is, for example, 1-3, which is obtained according to experimental tests, and if the difference between the indoor temperature and the set temperature is not large (especially if the startup time is long and the indoor temperature is relatively stable), the adjusted frequency does not need to be too large.
For example, after the compressor is restarted after meeting the second preset condition after each shutdown of the compressor, the compressor is operated for 10min (fourth preset time), and then Δ t (when cooling, Δ t ═ t) is determinedIndoor use-tIs provided withWhen heating, Δ t is tIs provided with-tIndoor use) When the detection delta t is larger than 0 for continuous 3min (fifth preset time), correcting the target frequency FN＝FNAnd + D Δ t, preventing the set temperature from being not reached due to too low frequency.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the air conditioner control method provided by the present invention with a specific embodiment.

Optionally, when the second determining unit determines that the fifth preset time of the indoor environment temperature satisfies the fourth preset condition, the frequency correcting unit corrects the current target frequency.
Specifically, the frequency correction unit determines the corrected target frequency according to the following formula based on the difference Δ t between the indoor ambient temperature and the set temperature during the cooling operation or the difference Δ t between the set temperature and the indoor ambient temperature during the heating operation.
FN＝FN+D*Δt
Wherein, FND is a correction coefficient for the current target frequency, and can be obtained through experiments.
In order to avoid that the target frequency is corrected when the temperature cannot reach the temperature set by the user after the previous shutdown and startup, the value of the correction coefficient D is, for example, 1-3, which is obtained according to experimental tests, and if the difference between the indoor temperature and the set temperature is not large (especially if the startup time is long and the indoor temperature is relatively stable), the adjusted frequency does not need to be too large.
For example, after the compressor is restarted after meeting the second preset condition after each shutdown of the compressor, the compressor is operated for 10min (fourth preset time), and then Δ t (when cooling, Δ t ═ t) is determinedIndoor use-tIs provided withWhen heating, Δ t is tIs provided with-tIndoor use) When the detection delta t is larger than 0 for continuous 3min (fifth preset time), correcting the target frequency FN＝FNAnd + D Δ t, preventing the set temperature from being not reached due to too low frequency.
