As shown in fig. 2, which is a schematic flowchart illustrating an embodiment of a frequency control method for an air conditioner compressor according to an embodiment of the present invention, the frequency control method for an air conditioner compressor includes steps S201 to S203:
s201, when detecting that the compressor is stopped at a temperature within the operation period of the air conditioner, acquiring the Wen Gong time length and the temperature reaching operation frequency corresponding to Wen Tingji of the compressor.
The operation period of the air conditioner is a period between when the air conditioner is started after power-on and works corresponding to a certain work mode until the work mode is switched, and a period between when the air conditioner is started after power-on and works corresponding to a certain work mode until the air conditioner is turned off, wherein the work mode includes, for example: refrigeration work, heating work and the like, it can be understood that the compressor is controlled to stop or start for multiple times according to the indoor environment temperature in one operation period of the air conditioner, for example, the indoor temperature is greater than the set temperature of the air conditioner to control the start of the compressor, and when the indoor temperature is less than or equal to the set temperature of the air conditioner, the compressor is controlled to reach Wen Tingji; it can be further understood that the set temperature of the air conditioner may be a preset temperature corresponding to the working mode of the air conditioner, or a target set temperature reached by an expected indoor temperature collected by a user through a parameter collecting device such as an air conditioner remote controller.
Further, it can be understood that the compressor is stopped when reaching a temperature, that is, the compressor of the air conditioner is controlled to stop when detecting that the indoor environment temperature meets a preset compressor stop condition when reaching the temperature; it can be understood that the preset compressor temperature-reaching shutdown condition, for example, in the air conditioner refrigeration working mode, the indoor environment temperature is equal to the set temperature of the air conditioner, or the indoor environment temperature is less than the set temperature of the air conditioner and the temperature difference between the indoor environment temperature and the set temperature of the air conditioner is equal to the preset temperature difference threshold value, and the specific temperature-reaching shutdown condition may be set according to the actual requirement.
The duration of Wen Gong is, that is, the period of the warm-up shutdown corresponding to the compressor of the air conditioner when the warm-up shutdown is detected, it can be understood that the duration is the operation duration of the compressor in the work cycle corresponding to the warm-up shutdown, that is, the work duration during which the compressor is started up to the shutdown.
It can be understood that the time length of the work reaching temperature can be determined according to the starting time and the stopping time by acquiring the time when the compressor is started and the time when the compressor is stopped, and determining the time length of Wen Gong.
The up-to-temperature operation frequency is that when the compressor receives the up-to-temperature shutdown instruction, the corresponding compressor operation frequency, for example, when the compressor operates at 100 hz/s, receives the up-to-temperature shutdown instruction, that is, the up-to-temperature operation frequency is 100 hz/s.
Specifically, in this embodiment of the application, the air condition compressor frequency control method is applied to an air condition compressor frequency control device, the air condition compressor frequency control device is arranged in an air conditioner, that is, the air conditioner is in an air conditioner operation period, when it is detected that the indoor temperature meets a preset compressor temperature-reaching shutdown condition (that is, it is detected that the compressor reaches Wen Tingji), the current operation frequency of the compressor is obtained, the current operation frequency is set to be the temperature-reaching operation frequency, and the shutdown time, according to the compressor start-up time and the shutdown time, the temperature-reaching work-doing time duration corresponding to Wen Tingji of the compressor is determined, and the compressor is controlled to reach Wen Tingji.
S202, determining the target operation frequency of the compressor according to the temperature reaching operation frequency and time length change information between the Wen Gong time length reaching time length and the history Wen Gong time length reaching time length.
The historical temperature reaching Wen Gong time length is the historical temperature reaching work doing time length corresponding to the historical temperature reaching stop of the compressor in the air conditioner operation period; that is, the operation period of the air conditioner is from Wen Gong duration corresponding to the first warm-up shutdown to Wen Gong duration corresponding to the last warm-up shutdown, it is understood that the number of the durations of Wen Gong in the history may not be limited, for example:
in one embodiment of the application, the air conditioner detects that the compressor is in a warm-up shutdown state in an air conditioner operation period, namely, the time for reaching Wen Gong corresponding to the warm-up shutdown state of the compressor is obtained, and after the target frequency is determined in one day according to the previously collected historical time for reaching Wen Gong, the time is set to be Wen Gong time, namely, when the next time the compressor is detected to reach Wen Tingji in the air conditioner operation period, the time and the previously collected historical time for reaching Wen Gong are used as the historical warm-up power-making time to be used together, namely, as the air conditioner operation period is normal, the number of times of reaching the warm-up shutdown is increased, the number of the historical warm-up power-making times is also increased, the database of the historical data for reaching Wen Gong time is dynamically updated, and the accuracy of the data is increased.
In another embodiment of the application, the number of the historical temperature-reaching work-doing durations of the air conditioner is too large due to the fact that the operation period of the air conditioner is too long, the data calculation amount is too large, at this time, the upper limit of the number of the historical temperature-reaching work-doing durations of Wen Gong can be set, and when the number of the historical temperature-reaching work-doing durations reaches the upper limit value, the value includes the historical temperature-reaching work-doing durations corresponding to the historical temperature-reaching work-doing shutdown corresponding to the latest time corresponding to the current temperature-reaching shutdown of the compressor, which corresponds to the upper limit value.
Specifically, the target operation frequency is used for controlling an operation frequency corresponding to the next start of the compressor in an operation period of the air conditioner, wherein a specific implementation manner of the target operation frequency of the compressor is determined according to the temperature-reaching operation frequency and the time length change information between the time length of Wen Gong and the time length of Wen Gong in history, which is not specifically limited in this application, for example:
the first implementation can be realized: after obtaining Wen Gong time duration and temperature reaching operation frequency corresponding to Wen Tingji of the compressor, the air conditioner calculates a temperature difference value between Wen Gong time duration and Wen Gong time duration, for example, calculates a difference value between the temperature reaching work duration and any Wen Gong time duration, or calculates a difference value between Wen Gong time durations adjacent to each other on a time axis in sequence according to a time sequence corresponding to Wen Gong time duration, and a difference value between the temperature reaching work duration and a last temperature reaching work duration corresponding to a temperature stop machine, then calculates a mean value of all the difference values to obtain a mean value difference value, and then searches a preset mapping table according to the difference value/mean value difference value and the temperature reaching operation frequency to determine a target operation frequency.
The second embodiment can be realized: after obtaining Wen Gong time duration and temperature reaching operation frequency corresponding to Wen Tingji of the compressor, the air conditioner calculates a temperature difference value between the temperature reaching work duration and any historical Wen Gong time duration, calculates a temperature difference change rate between the temperature reaching work duration and the historical Wen Gong time duration, determines an adjustment frequency for adjusting the temperature reaching operation frequency according to the temperature difference change rate and the temperature difference value, and determines a target operation frequency of the compressor according to the adjustment frequency and the temperature reaching operation frequency.
The third implementation can be realized: after the air conditioner obtains the Wen Gong duration and the temperature reaching operation frequency corresponding to Wen Tingji of the compressor, the duration change rate of the time sequence corresponding to Wen Gong duration and Wen Gong historical duration is calculated, the adjusting frequency for adjusting the temperature reaching operation frequency is determined according to the duration change rate, and the target operation frequency of the compressor is determined according to the adjusting frequency and the temperature reaching operation frequency.
S203, when the indoor temperature of the environment corresponding to the air conditioner is detected to meet the preset compressor starting condition, controlling the compressor to run at the target running frequency.
The air conditioner corresponds to an indoor temperature of an environment, that is, the air conditioner outputs an indoor ambient temperature corresponding to work, for example, an ambient temperature of an indoor installation environment.
The preset compressor starting condition, that is, the condition for controlling the starting of the compressor, may be designed according to actual requirements, for example, when the working mode corresponding to the operation cycle of the air conditioner is the cooling mode, the preset compressor starting condition may be that the indoor temperature is greater than the set temperature corresponding to the cooling mode of the air conditioner; or the indoor temperature is higher than the set temperature corresponding to the refrigeration mode of the air conditioner, and the temperature difference between the indoor temperature and the set temperature corresponding to the refrigeration mode of the air conditioner is higher than a preset temperature difference threshold value.
Specifically, when the air conditioner detects that the compressor reaches the temperature and stops the machine in the running period of the air conditioner, after Wen Gong time duration and reaching the temperature running frequency corresponding to Wen Tingji of the compressor are obtained, according to the reaching temperature running frequency and time duration change information between Wen Gong time duration and Wen Gong time duration in history, the target running frequency of the compressor is determined, the indoor temperature is detected, if the indoor temperature meets preset compressor starting conditions, the compressor is controlled to be started and frequency-raised until the running frequency of the compressor reaches the target running frequency, and the compressor is controlled to run at the target running frequency.
Further, on the basis of the above embodiment, in an embodiment of the determination of the target operating frequency in the frequency control method of the air conditioner compressor, the time length change information includes a target time length difference value and a target time length change rate.
Referring to fig. 3, fig. 3 is a schematic flow chart of one embodiment of determining a target operating frequency in a frequency control method of an air conditioner compressor provided in an embodiment of the present application, and includes steps S301 to S304:
s301, if the number of times that the history of the compressor reaches Wen Tingji in the operation period of the air conditioner is larger than a first preset stop number, obtaining the history temperature-reaching work-doing duration corresponding to the history temperature-reaching stop of the compressor.
The historical warm-up shutdown times of the compressor are, that is, the times of the warm-up shutdown of the compressor, which are already occurred except for the currently detected warm-up shutdown of the compressor in the air conditioner operation cycle, for example, when it is detected that the compressor reaches Wen Tingji in the air conditioner operation cycle, if the compressor reaches the warm-up shutdown for the third time in the air conditioner operation cycle, the times of the historical warm-up shutdown of the compressor reaches Wen Tingji is 2 times.
It can be understood that the number of times of shutdown at the temperature of the compressor is accumulated when the compressor reaches Wen Tingji is detected during the air conditioner operation period, and the accumulated data is cleared when the air conditioner operation period is ended, i.e., it can be understood that the number of times of shutdown at the temperature of the history of the compressor of the air conditioner can be directly acquired.
The first preset shutdown time is used to determine whether a target duration change rate can be calculated according to the Wen Gong duration and the history Wen Gong duration, and it can be understood that, if the history temperature-reaching shutdown time is less than two times, the number of the history temperature-reaching power-doing durations is also less than 2, and at this time, the target duration change rate cannot be calculated according to the history temperature-reaching Wen Gong duration and the history temperature-reaching Wen Gong duration, that is, it can be understood that the first preset shutdown time is greater than or equal to 2.
Specifically, when the air conditioner detects that the compressor reaches Wen Tingji in the operation period of the air conditioner, the historical temperature reaching shutdown times are obtained, whether the historical temperature reaching shutdown times are larger than a first preset shutdown time or not is judged, and if the historical temperature reaching Wen Tingji times of the compressor in the operation period of the air conditioner are larger than the first preset shutdown time, the historical temperature reaching work-doing duration corresponding to the historical temperature reaching shutdown of the compressor is obtained.
S302, calculating the target time length difference between the current Wen Gong time length and any one of the historical temperature reaching and work doing time lengths Wen Gong.
In an embodiment of the present application, the any history temperature-reaching work-doing time length may be a history temperature-reaching work-doing time length corresponding to a last detected temperature-reaching shutdown, or may be a history temperature-reaching work-doing time length Wen Gong corresponding to a last detected temperature-reaching shutdown, where, when any history reaches Wen Gong, the history temperature-reaching work-doing time length corresponding to a last detected temperature-reaching shutdown, that is, the history temperature-reaching work-doing time length corresponding to a current time interval that is the shortest is Wen Gong.
