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 air conditioner control method includes at least step S110 and step S120.
And step S110, under the condition of the air conditioner refrigeration operation, when the air conditioner enters the anti-freezing control, judging whether the interval time between the current time and the last time of entering the anti-freezing control is less than a set time threshold value.
Specifically, after the air conditioner starts to perform cooling operation, whether the air conditioner meets an anti-freezing control condition is detected, where the anti-freezing control condition may specifically include that a temperature of an indoor heat exchanger of the air conditioner (specifically, a temperature of an inner pipe) is lower than a preset anti-freezing protection temperature value, that is, when the temperature of the indoor heat exchanger of the air conditioner is lower than the preset anti-freezing protection temperature value, it is determined that the air conditioner meets the anti-freezing control condition, and the air conditioner enters anti-freezing control. For example, the anti-freezing protection temperature value is 3 ℃, and when the temperature of the inner pipe detected by the evaporator temperature sensing bulb is lower than 3 ℃, the air conditioning unit enters into anti-freezing protection.
And when the anti-freezing control condition is met, entering anti-freezing control, and judging whether the interval time between the current time (namely the time for entering the anti-freezing control at this time) and the time for entering the anti-freezing control at the last time is less than a set time threshold value. The set time threshold may be obtained experimentally. When the air conditioner meets the anti-freezing control condition again and enters the anti-freezing control, the current time, namely the time of entering the anti-freezing control this time is recorded, and whether the interval time t between the current time and the time of entering the anti-freezing control last time is smaller than a set time threshold t or not is judgedSetting upI.e. whether t satisfies t < tSetting upAnd then, when the air conditioner enters the anti-freezing control each time, judging whether the interval time between the current time (the time for entering the anti-freezing control at this time) and the time for entering the anti-freezing control at the last time is less than a set time threshold value.
And step S120, if the interval time is judged to be smaller than the set time threshold, compensating the target frequency of the compressor according to the times of the air conditioner entering the anti-freezing control at the current ambient temperature and the set temperature.
If the interval time t is judged to be more than or equal to the set time threshold tSetting up(t≥tSetting up) And the air conditioner operates normally. If the interval time is judged to be less than the set time threshold (t < t)Setting up) And compensating the target frequency of the compressor according to the times of the air conditioner entering the anti-freezing control at the current environment temperature and the set temperature. The ambient temperature may specifically be an indoor ambient temperature.
Specifically, a compressor target frequency compensation value corresponding to the times of entering anti-freezing control at the current ambient temperature and the set temperature is obtained according to the preset corresponding relationship between the times of entering anti-freezing control and the target frequency compensation value; and compensating the target frequency of the compressor according to the obtained target frequency compensation value of the compressor to obtain the compensated target frequency of the compressor.
In one embodiment, a preset correspondence table between the number of times of entering the anti-freeze control and the target frequency compensation value is used, and the compressor target frequency compensation value corresponding to the number of times of entering the anti-freeze control at the current ambient temperature and the set temperature is searched from the correspondence table. For example, the correspondence table of the number of times of entering the anti-freeze control and the target frequency compensation value may refer to table 1:
TABLE 1
For example, the set target frequency of the air conditioning unit is 50Hz under the current ambient temperature and the set temperature, and the unit meets t ≧ t during the first anti-freezing controlSetting upAt this time, the corresponding compressor target frequency under the current environment temperature and the set temperature is corrected to be 48Hz, if the current environment temperature and the set temperature are still met, the compressor target frequency is corrected to be 46Hz, and the like.
Fig. 2 is a method schematic diagram of another embodiment of the air conditioner control method provided by the invention. As shown in fig. 2, according to another embodiment of the present invention, the air conditioning control method further includes step S130.
And step S130, after the target frequency of the compressor is compensated, when the air conditioner enters the anti-freezing control again, if the interval time between the current time and the last time of entering the anti-freezing control is judged to be greater than or equal to the set time, setting the compensated target frequency of the compressor as the target frequency of the compressor of the air conditioner at the current ambient temperature and the set temperature.
Specifically, after the target frequency of the compressor is compensated, whether t is more than or equal to t is continuously detected and judgedSetting upUntil t is more than or equal to tSetting upAnd memorizing the target frequency B of the compensated compressor at the moment, the ambient temperature and the set temperature at the moment, and memorizing the target frequency B of the compressor of the air conditioning unit at the moment by the unit, wherein the frequency B of the compressor at the moment is the target frequency of the compressor of the air conditioning unit at the ambient temperature and the set temperature at the moment. When the unit operates under the same environment temperature and set temperature conditions, the unit operates according to the memorized frequency B as the target frequency of the compressor.
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.
Fig. 3 is a schematic method diagram of an embodiment of an air conditioner control method according to the present invention. The embodiment shown in fig. 3 includes steps S201 to S207.
In step S201, the air conditioner performs a cooling operation at an initial compressor target frequency a.
And S202, when the unit meets the condition of entering the anti-freezing control, recording the time t from the beginning of entering the anti-freezing of the unit to the next entering of the anti-freezing.
Step S203, judging whether t is less than tSetting upIf t < t is satisfiedSetting upThen step S204 is executed, if t < t is not satisfiedSetting upThen step S207 is executed.
Step S204, if t is less than tSetting upThen the target frequency of the compressor is compensated, currentCompressor target frequency a + offset X.
Step S205, the unit continuously detects and judges whether t is less than tSetting upIf t < t is satisfiedSetting upThen, the process returns to step S204 to continue to compensate the target frequency of the compressor. If t is not satisfied, t is less than tSetting upThen step S206 is performed.
Step S206, if t is not satisfied, t is less than tSetting upAnd recording the target frequency B of the compressor after compensation at the moment and the ambient temperature and the set temperature at the moment, namely when the unit runs at the same ambient temperature and the set temperature, the compressor runs according to the memorized frequency B as the target frequency.
Step S207, when t is not satisfied, t is less than tSetting upI.e. t ≧ tSetting upAnd in time, the unit normally operates.
Fig. 4 is a block diagram of an embodiment of an air conditioning control apparatus according to the present invention. As shown in fig. 4, the air conditioning control device 100 includes a determination unit 110 and a compensation unit 120.
The judging unit 110 is configured to, in a case of the air conditioner cooling operation, when the air conditioner enters the anti-freezing control, judge whether an interval time between a current time and a time when the air conditioner enters the anti-freezing control last time is smaller than a set time threshold; the compensating unit 120 is configured to compensate the target frequency of the compressor according to the number of times that the air conditioner enters the anti-freezing control at the current ambient temperature and the set temperature if the determining unit determines that the interval time is smaller than the set time threshold.
Specifically, after the air conditioner starts to perform cooling operation, whether the air conditioner meets an anti-freezing control condition is detected, where the anti-freezing control condition may specifically include that a temperature of an indoor heat exchanger of the air conditioner (specifically, a temperature of an inner pipe) is lower than a preset anti-freezing protection temperature value, that is, when the temperature of the indoor heat exchanger of the air conditioner is lower than the preset anti-freezing protection temperature value, it is determined that the air conditioner meets the anti-freezing control condition, and the air conditioner enters anti-freezing control. For example, the anti-freezing protection temperature value is 3 ℃, and when the temperature of the inner pipe detected by the evaporator temperature sensing bulb is lower than 3 ℃, the air conditioning unit enters into anti-freezing protection.
When meeting the anti-freezing requirementWhen the freezing control condition enters the anti-freezing control, the determining unit 110 determines whether the interval between the current time (i.e., the time of entering the anti-freezing control this time) and the time of entering the anti-freezing control last time is less than a set time threshold. The set time threshold may be obtained experimentally. When the air conditioner meets the anti-freezing control condition again and enters the anti-freezing control, the current time, that is, the time of entering the anti-freezing control this time is recorded, and the determining unit 110 determines whether the interval time t between the current time and the time of entering the anti-freezing control last time is less than the set time threshold tSetting upI.e. whether t satisfies t < tSetting upThereafter, each time the air conditioner enters the anti-freeze control, the determination unit 110 determines whether the interval between the current time (the time of entering the anti-freeze control this time) and the time of entering the anti-freeze control last time is less than a set time threshold.
If the determining unit 110 determines that the interval time is smaller than the set time threshold, the compensating unit 120 compensates the target frequency of the compressor according to the number of times that the air conditioner enters the anti-freezing control at the current ambient temperature and the set temperature.
If the determining unit 110 determines that the interval time t is greater than or equal to the set time threshold tSetting up(t≥tSetting up) And the air conditioner operates normally. If the determination unit 110 determines that the interval time is less than the set time threshold (t < t)Setting up) The compensating unit 120 compensates the target frequency of the compressor according to the number of times that the air conditioner enters the anti-freezing control at the current ambient temperature and the set temperature. The ambient temperature may specifically be an indoor ambient temperature.
Specifically, the compensating unit 120 obtains a compressor target frequency compensation value corresponding to the number of times of entering the anti-freezing control at the current ambient temperature and the set temperature according to the preset corresponding relationship between the number of times of entering the anti-freezing control and the target frequency compensation value; and compensating the target frequency of the compressor according to the obtained target frequency compensation value of the compressor to obtain the compensated target frequency of the compressor.
In one embodiment, a preset correspondence table between the number of times of entering the anti-freeze control and the target frequency compensation value is used, and the compressor target frequency compensation value corresponding to the number of times of entering the anti-freeze control at the current ambient temperature and the set temperature is searched from the correspondence table. For example, the correspondence table of the number of times of entering the anti-freeze control and the target frequency compensation value may refer to table 1:
TABLE 1
For example, the set target frequency of the air conditioning unit is 50Hz under the current ambient temperature and the set temperature, and the unit meets t ≧ t during the first anti-freezing controlSetting upAt this time, the corresponding compressor target frequency under the current environment temperature and the set temperature is corrected to be 48Hz, if the current environment temperature and the set temperature are still met, the compressor target frequency is corrected to be 46Hz, and the like.
Fig. 5 is a block diagram of another embodiment of the air conditioning control apparatus according to the present invention. As shown in fig. 5, the air conditioning control apparatus 100 further includes a setting unit 130.
The determining unit 110 is further configured to determine, after compensating for the target compressor frequency, whether an interval between the current time and the last time of entering the anti-freeze control is greater than or equal to the set time when the air conditioner enters the anti-freeze control again; the setting unit 130 is configured to set the compensated target frequency of the compressor as the target frequency of the air conditioner at the current ambient temperature and the set temperature if the determining unit determines that the interval time between the current time and the time of entering the anti-freeze control last time is greater than or equal to the set time.
Specifically, after compensating for the target frequency of the compressor, the determining unit 110 continuously detects and determines whether t ≧ t is satisfiedSetting upUntil t is more than or equal to tSetting upThe compensated target frequency B of the compressor at this time, and the ambient temperature and the set temperature at this time are memorized, and the setting unit 130 sets the target frequency B of the compressor at this timeAnd the set memorizes the compressor frequency B at the moment, namely the compressor target frequency of the air conditioning unit at the moment under the environment temperature and the set temperature. When the unit operates under the same environment temperature and set temperature conditions, the unit operates according to the memorized frequency B as the target frequency of the compressor.

Therefore, according to the scheme provided by the invention, when the interval time between the current entering of the anti-freezing control and the last entering of the anti-freezing control is judged to be less than the set time threshold, the target frequency of the compressor is compensated according to the times that the air conditioner enters the anti-freezing control at the current environmental temperature and the set temperature, so that the influence on user experience caused by frequent entering of the unit into the anti-freezing control can be avoided, the effect of low-temperature continuous refrigeration non-attenuation is achieved, the refrigeration requirement of the system under the low-temperature working condition is met, the system problems of large-area frosting of the evaporator, poor heat exchange of the internal machine, complete evaporation of the liquid refrigerant and the like of the compressor can be avoided, and.
