Referring to fig. 1, an embodiment of the present disclosure provides an air conditioner control method, which may include:
and S2, determining whether the air conditioner satisfies a defrost mode exit condition.
If the outdoor heat exchanger of the air conditioner is frosted and normal operation of the air conditioner is affected, the air conditioner needs to enter a defrosting mode to defrost the outdoor heat exchanger. When the normal operation of the air conditioner is not affected after the frost on the outdoor heat exchanger of the air conditioner is removed or a portion thereof is removed, the defrosting mode needs to be exited.
Before exiting the defrost mode, the exit conditions for the defrost mode need to be met. The condition that the air conditioner meets the defrosting mode exit condition can be used for representing the defrosting end of the air conditioner.
In some embodiments, whether the air conditioner satisfies the defrosting mode exit condition is determined according to the distribution of frost on the outdoor heat exchanger of the air conditioner.
Illustratively, the distribution condition of frost in the outdoor heat exchanger can be detected through a humidity sensor and/or a temperature sensor of the outdoor heat exchanger.
In some embodiments, whether the air conditioner satisfies the defrost mode exit condition is determined according to a temperature of the outdoor heat exchanger when the air conditioner operates in the defrost mode and/or an operation time period during which the air conditioner operates in the defrost mode.
The time length required for completing the defrosting of the outdoor heat exchanger of the air conditioner can be known in advance according to big data statistics, so whether the defrosting is finished or not can be determined according to the running time length of the air conditioner in a defrosting mode.
In some embodiments, the defrost mode exit condition may include at least one of:
the temperature of the outdoor heat exchanger when the air conditioner works in the defrosting mode is higher than a preset temperature value;
when the air conditioner works in the defrosting mode, the duration that the temperature of the outdoor heat exchanger is higher than a preset temperature value is longer than a preset duration;
the running time of the air conditioner working in the defrosting mode is longer than the preset running time.
It is understood that whether the air conditioner satisfies the defrost mode exit condition may also be determined in other manners, which is not specifically limited by the embodiments of the present disclosure.
And S4, when the air conditioner meets the condition of exiting the defrosting mode, controlling the running frequency of the compressor of the air conditioner to be maintained at the preset frequency until the air conditioner exits the defrosting mode.
Here, the preset frequency is lower than an operation frequency of a compressor of the air conditioner when the air conditioner is in the defrosting mode. Wherein, the preset frequency is set as a frequency with a value larger than 0.
In this step, when the operating frequency of the compressor is maintained at the preset frequency for a period of time up to the preset period of time, the reversing valve of the air conditioner may be controlled to reverse, and when the reversing valve completes the reversing, it is determined that the air conditioner exits the defrost mode.
In this embodiment, when the air conditioner satisfies the condition for exiting the defrost mode, the operating frequency of the compressor of the air conditioner is controlled to be reduced to the preset frequency, and the air conditioner is maintained to operate at the preset frequency with the value greater than 0. Therefore, the air conditioner compressor does not need to be stopped before the reversing of the reversing valve is controlled subsequently, the compressor does not need to be restarted after the reversing valve finishes reversing, in this case, the frequency of the compressor can be directly increased, the frequency of the compressor is quickly increased, the temperature of the air conditioner in a target space can be quickly increased by the increased frequency compressor, the influence degree of the air conditioner on the temperature of the target space where the air conditioner is located due to defrosting is reduced, the duration of the indoor temperature influenced by defrosting is shortened, the stability of the air conditioner on the temperature control of the target space where the air conditioner is located is improved, and the experience effect of a user is improved.
S6, when the air conditioner exits the defrosting mode, controlling the compressor of the air conditioner to increase the operating frequency of the compressor to a target frequency in a preset frequency span; wherein the target frequency is greater than a preset frequency; presetting a frequency span of N x F, wherein F is the minimum frequency span of the air conditioner during frequency adjustment; n is a positive number equal to 2 or greater than 2.
The frequency span refers to a frequency range of one-time frequency increase of the compressor in unit time, and the frequency span is smaller than or equal to the maximum value of the operation frequency range of the compressor.
The frequency of the compressor is increased in a frequency increasing mode with minimum frequency span, which can be simply understood as a frequency sweeping mode of the compressor. The compressor is in a frequency increasing mode with the preset frequency span, and the preset frequency span is larger than the minimum frequency span of the compressor, so that the frequency increasing of the air conditioner compressor is realized, and the rapid frequency increasing of the compressor can be realized.
The preset frequency span may be set according to the actual operation performance of the air conditioner, and is not specifically limited herein.
It can be understood that a period of time for which the operating frequency of the compressor is increased from the preset frequency to the target frequency by the preset frequency span is less than a period of time for which the operating frequency of the compressor is increased from the preset frequency to the target frequency by the minimum frequency span.
The embodiment of the disclosure provides an air conditioner control method, which includes determining whether an air conditioner meets a defrosting mode exit condition; when the air conditioner meets the condition of quitting the defrosting mode, controlling the running frequency of a compressor of the air conditioner to be maintained at a preset frequency until the air conditioner quits the defrosting mode, and controlling the compressor of the air conditioner to increase the running frequency of the compressor to a target frequency by a preset frequency span after the air conditioner quits the defrosting mode; wherein the target frequency is greater than a preset frequency; presetting a frequency span of N x F, wherein F is the minimum frequency span of the air conditioner during frequency adjustment; n is a positive number equal to or greater than 2, and may range from 2 to 20, for example, and preferably may range from 4 to 16.
So, through adopting the preset frequency span that is higher than the minimum frequency span of air conditioner when frequency adjustment, the operating frequency with the compressor is upscaled to the target frequency, can make the compressor of air conditioner to be upscaled fast after the defrosting finishes, realize heating fast promptly after the compressor is upscaled fast, thereby make the air conditioner can blow off comfortable temperature fast, reduce because the defrosting leads to the influence degree that the air conditioner received to its place target space temperature, and reduce the duration that indoor temperature received the defrosting influence, promote the stability of air conditioner to its place target space's temperature control, user's experience effect has been promoted.
In some embodiments, as shown in fig. 2, the step S6, when the air conditioner exits the defrosting mode, the step S6 of controlling the compressor of the air conditioner to increase the operating frequency of the compressor to the target frequency by a preset frequency span may include:
and S62, when the air conditioner exits the defrosting mode, acquiring a first temperature value in the target space of which the temperature is regulated by the air conditioner.
Here, the target space to be temperature-conditioned is a space in which an air conditioner is located, and the target space may be any indoor space, and may be, for example, a closed or semi-closed space such as a living room, a bedroom, a studio, a classroom, a reading room, an office, or a greenhouse.
Here, the first temperature value is an ambient temperature in the target space after the air conditioner exits the defrosting mode, and the first temperature value may be obtained in real time by a temperature detection device provided in the target space, wherein the temperature detection device may be a temperature sensor provided at an air outlet of the indoor heat exchanger.
And S64, determining whether the first temperature value in the target space meets a preset condition.
Here, the preset condition may be set according to the actual application requirement, and this embodiment does not specifically limit this.
For example, the preset condition may be: and the difference value between the first temperature value and a second temperature value in the target space when the air conditioner enters the defrosting mode is higher than the temperature difference threshold value.
For another example, the preset condition may be: and the difference value between the first temperature value and the target temperature value of the temperature in the air-conditioning target space is higher than the temperature difference threshold value.
For another example, the preset condition may be: the first temperature value is lower than a temperature threshold value, or a difference value obtained by subtracting the first temperature value from the temperature threshold value is larger than a preset value. Here, the preset value may be set according to the actual application requirement, for example, the preset value may be set to any temperature value with a value greater than 2 ℃.
For another example, the preset condition may be: the difference between the first temperature value and the second temperature value is above a temperature difference threshold, and the first temperature value is below a temperature threshold, and so on.
In some examples, the implementation of step S64 may include at least one of:
when the first temperature value is lower than the temperature threshold value, determining that the first temperature value meets a preset condition;
when the difference value between the second temperature value and the first temperature value is higher than the temperature difference threshold value, determining that the first temperature value meets the preset condition, wherein the second temperature value is as follows: and when the air conditioner enters the defrosting mode, the temperature value in the target space, or the target temperature value of the temperature in the target space is adjusted by the air conditioner.
The temperature threshold may be an optimal heating temperature pre-stored in the air conditioner. Here, the optimal heating temperature may be set to any value within an optimal heating temperature range, the optimal heating temperature range may be obtained through training of a large amount of experimental data, or may be determined through expert experience, and for example, the optimal heating temperature range may be 20 ℃ to 26 ℃.
The target temperature value for adjusting the temperature in the target space by the air conditioner may be preset by a user according to a self requirement, or may be an optimal energy-saving temperature determined according to actual operation energy consumption of the air conditioner, which is not specifically limited in this embodiment.
The temperature difference threshold may be set according to actual application requirements, and exemplarily, the value range of the temperature difference threshold may be 2 ℃ to 4 ℃, which is not specifically limited in this embodiment.
And S66, when the first temperature value meets the preset condition, controlling the compressor of the air conditioner to increase the operating frequency of the compressor to the target frequency in the preset frequency span.
For example, assuming that the temperature difference threshold is set to 2 ℃, when a temperature attenuation value (i.e., a difference obtained by subtracting a first temperature value in the target space after the air conditioner exits the defrost mode from a second temperature value in the target space when the air conditioner enters the defrost mode) in the target space before and after the defrost is higher than 2 ℃, it is determined that the first temperature value satisfies a preset condition, so that the compressor can be controlled to be upscaled to the target frequency at a preset frequency span.
In the embodiment of the disclosure, when the first temperature value satisfies the preset condition, the compressor of the air conditioner is controlled to raise the operating frequency of the compressor to the target frequency in the preset frequency span, so that the compressor of the air conditioner can be controlled to raise the frequency quickly, the air conditioner use experience of a user is promoted, and the operating energy consumption of the air conditioner is reduced.
In some embodiments, if the first temperature value does not satisfy the preset condition, that is, the air conditioner is operating in the defrosting mode, and the influence on the temperature regulation and control in the target space is not great, in this case, the frequency raising of the compressor may not be performed in a cross-frequency raising manner, and the frequency raising of the compressor may be performed by continuously using the sweep frequency, so that wear and the like possibly caused by the cross-frequency raising of the compressor are reduced.
In some embodiments, the target frequency is: the maximum operating frequency of the compressor before the air conditioner enters the defrost mode.
The maximum operating frequency of the compressor before the air conditioner enters the defrosting mode may be the maximum operating frequency of the compressor within a preset time period before the air conditioner enters the defrosting mode. It will be appreciated that the operating frequency of the compressor at a time may be determined based on the ambient temperature within the target space, the target temperature, and the ambient temperature outside the target space at that time.
In the embodiment of the disclosure, after the air conditioner exits the defrosting mode, the running frequency of the compressor is increased to the highest running frequency of the compressor before the air conditioner enters the defrosting mode by controlling the compressor to span with the preset frequency, so that the temperature of the air outlet of the air conditioner can be recovered to the temperature before the air conditioner enters the defrosting mode, and the air conditioner use experience of a user can be improved.
In some embodiments, the rate of raising the operating frequency of the compressor at the preset frequency span is higher than the rate of raising the operating frequency of the compressor at the minimum frequency span.
In the embodiment of the present disclosure, the frequency-up rate when frequency-up is performed by the minimum frequency span may be 2Hz to 5 Hz/sec, and the frequency-up rate when frequency-up is performed by the preset frequency span may be 20Hz to 30 Hz/sec. Therefore, the compressor can be rapidly increased in frequency, and the air conditioner can rapidly blow out comfortable temperature.
In some embodiments, when the operating frequency of the compressor is controlled to be increased by a preset frequency span, the operating frequency of the air conditioner compressor does not stay at a frequency point where each compressor can stay, and the compressor does not stay at the preset frequency stay point.
Generally, at least one frequency stop point (for example, the frequency stop point may be 20Hz, 30Hz, 40Hz, and the like) is preset in an operating frequency range of the compressor, and each time the operating frequency of the compressor reaches the preset frequency stop point, the operating frequency of the compressor stops at the frequency stop point, and the compressor is raised after the stop time reaches the preset stop time. And in this embodiment, when the operating frequency with predetermineeing the frequency span control compressor rises frequently, the operating frequency through control compressor does not stay and does not predetermine the frequency dwell point, can make the compressor rise frequently more like this to can make air conditioner air outlet temperature promote fast.
In some embodiments, as shown in fig. 3, based on fig. 1, the method may further include:
and S5, controlling the opening degree of an expansion valve of the air conditioner to be reduced to a preset opening degree when the air conditioner meets the defrosting mode exit condition.
And S7, after the air conditioner exits the defrosting mode, controlling the opening degree of an expansion valve of the air conditioner to be increased to a target opening degree, wherein the target opening degree is larger than a preset opening degree.
Here, the expansion valve of the air conditioner is a throttle member located on a refrigerant pipe between an outdoor unit and an indoor unit of the air conditioner. The opening degree of the expansion valve can be used for determining the refrigerant flow rate and the refrigerant flow speed on the refrigerant pipeline. The larger the opening degree of the expansion valve is, the larger the refrigerant flow rate and the refrigerant flow rate speed are.
