Description
Technical Field
The invention relates to the field of control of air conditioners, in particular to a control method of an air conditioner, the air conditioner and a computer readable storage medium.
Background
Some air conditioners are provided with two air ducts, and the air inlet ends of the two air ducts are positioned at the same centrifugal fan, for example, the centrifugal fan of the chinese utility model patent application with publication number CN209026954U corresponds to an upper air duct and a lower air duct, and for example, the centrifugal fan of the chinese invention patent application with publication number CN111197852A corresponds to an upper air duct and a lower air duct, and both the upper air duct and the lower air duct are provided with openable baffles; therefore, the air outlet quantity of the air conditioner during operation can be increased under the condition that the centrifugal fan is not increased, and the uniformity of the air conditioner for improving the temperature values of all places of the indoor environment can be improved by exhausting air from different positions.
However, when the air conditioner is in operation, the air outlet of the air duct generates large noise, and after the number of the air ducts is increased, the noise is also increased along with the increase of the air outlet quantity.
Disclosure of Invention
An object of the present invention is to provide a control method of an air conditioner that is advantageous for rapidly improving an indoor ambient temperature and for reducing an operation noise of the air conditioner.
In order to achieve the above object, in the control method of the air conditioner provided by the present invention, the air conditioner includes a centrifugal fan, a first air duct, a second air duct and a wind shield, wherein an air inlet end of the first air duct and an air inlet end of the second air duct are both located at the centrifugal fan; the opening of the wind shield is adjustable and blocked in the second air duct; the control method comprises the following steps: when the first condition is met, or when the second condition is met, or when the third condition is met, or when any more than one of the first condition and the second condition is met, or when any more than one of the first condition and the third condition is met, or when any more than one of the second condition and the third condition is met, or when any more than one of the first condition, the second condition and the third condition is met, the wind deflector adjusts the opening degree of the second air duct to be the first opening degree, otherwise, the wind deflector adjusts the opening degree of the second air duct to be the second opening degree, and the second opening degree is larger than the first opening degree; if the air conditioner operates in the refrigeration working condition, then: the first condition is that the difference between the indoor environment temperature value and the adjustment target temperature value is smaller than a preset first threshold value; the second condition is that the indoor environment temperature value is smaller than a preset first temperature value; the third condition is that the indoor environment temperature value is smaller than the preset second temperature value and the outdoor environment temperature value is smaller than the preset third temperature value; the first temperature value is less than the second temperature value; if the air conditioner operates in the heating working condition, then: the first condition is that the difference between the adjustment target temperature value and the indoor environment temperature value is smaller than a preset second threshold value; the second condition is that the indoor environment temperature value is greater than a preset fourth temperature value; the third condition is that the indoor environment temperature value is greater than a preset fifth temperature value and the outdoor environment temperature value is greater than a preset sixth temperature value; the fourth temperature value is greater than the fifth temperature value.
From the above, on one hand, because the air conditioner of the invention is provided with the first air duct and the second air duct, and when the indoor environment temperature value is not in the temperature range which is comfortable for human body to feel, the opening degree of the second air duct is adjusted to be fully opened, which is favorable for improving the air outlet volume of the air conditioner under the condition and is convenient for improving the temperature of the indoor environment rapidly with larger air volume; on the other hand, when the condition of reducing the opening degree of the second air channel is met, the indoor environment temperature value is adjusted to a temperature interval which is comfortable for human bodies to feel, the requirement of users on the adjustment rate of the indoor environment temperature value is reduced, and the air conditioner of the embodiment is provided with the first air channel and the second air channel, so that the air outlet volume of the air conditioner is not reduced too much by reducing the opening degree of the second air channel, and the reduction of the opening degree of the second air channel does not cause obvious adverse effects on the user body feeling; in addition, the opening degree of the second air duct is reduced, so that the running noise of the air conditioner is reduced, the adverse effect of the running of the air conditioner on the normal work and life of a user is reduced, and the user experience is improved; particularly, the air conditioner of the invention has a short time for operating the second air duct fully opened (quickly adjusting the room temperature), and the air conditioner is normally operated only when operating the second air duct half opened, so that the arrangement of the embodiment is beneficial to reducing the noise of the air conditioner during most of the operation period.
In the control method for the air conditioner to operate under the refrigeration working condition, the second condition is judged by comparing the indoor environment temperature value with the preset first temperature value, so that the condition that the air conditioner operates with larger operation noise for a long time due to the fact that a user sets an excessively low adjustment target temperature value can be avoided; similarly, in the control method for the air conditioner to operate under the heating working condition, the second interface compares and judges the indoor environment temperature value and the preset fourth temperature value, so that the condition that the air conditioner operates for a long time under the condition of high operation noise due to the fact that a user sets an excessively high adjustment target temperature value can be avoided.
In addition, in the control method for the air conditioner to operate under the refrigeration working condition, the third condition is that the indoor environment temperature value and the preset second temperature value are compared and judged, the outdoor environment temperature value and the preset third temperature value are compared and judged, the second temperature value is larger than the first temperature value, and the setting of the third condition is further beneficial to reducing the operation noise of the air conditioner as early as possible under the condition that the user experience of the indoor environment temperature is not influenced.
One preferred scheme is that the first air duct, the centrifugal fan and the second air duct are distributed from top to bottom.
Another preferred solution is that the wind deflector is located at one end of the second air duct close to the centrifugal fan.
In another preferred embodiment, the minimum cross-sectional area of the first air duct is larger than the minimum cross-sectional area of the second air duct.
It is further preferred that the control method is performed once every first time interval.
Still another preferred scheme is that the air outlet of the first air duct is located at a position where the direct blowing cannot be performed on the user, and the air outlet of the second air duct is located at a position where the direct blowing is possible on the user.
It is thus clear that reducing the aperture in second wind channel after indoor environment temperature adjusts to the comfortable temperature of human body like this can also reduce the amount of wind and directly blow to user, is favorable to promoting user experience.
In another preferred embodiment, the sixth temperature value, the fifth temperature value, the fourth temperature value, the first temperature value, the second temperature value, and the third temperature value are sequentially increased.
It is a further object of the present invention to provide an air conditioner which is advantageous for rapidly improving the indoor ambient temperature and for reducing the operating noise of the air conditioner.
In order to achieve the above object, the air conditioner provided in the present invention has a processor and a memory, wherein the memory stores a computer program, and the computer program implements the steps of the control method of the air conditioner when executed by the processor.
It is a further object of the present invention to provide a computer-readable storage medium that facilitates rapid improvement of indoor ambient temperature and reduction of operating noise of an air conditioner.
In order to achieve the above object, the present invention provides a computer-readable storage medium having stored thereon a computer program, which when executed, realizes the steps of the control method of the air conditioner as described above.

In the control method for the air conditioner to operate in the heating condition, the judgment condition of the step two S22 is the first condition, the judgment condition of the step four S24 is the second condition, and the judgment condition of the step five S25 and the judgment condition of the step six S26 together constitute the third condition.
As can be seen from the above, in the present embodiment, when any one (or more than one) of the first condition, the second condition, and the third condition is satisfied, the opening degree of the second air duct 3 is adjusted to 50%, otherwise, the opening degree of the second air duct 3 is adjusted to 100%; of course, in other embodiments of the present invention, the determining order of the first condition, the second condition and the third condition may be adjusted, and in the control method for the air conditioner to operate in the cooling condition, the order of the step five S15 and the step six S16 in the third condition may also be exchanged; in the control method for the air conditioner to operate in the heating condition, the sequence of the step five S25 and the step six S26 in the third condition can be exchanged.
For example, when the air conditioner operates in a refrigeration working condition, the adjustment target temperature value is 22 ℃, the first temperature value is 25 ℃, the second temperature value is 29 ℃, the third temperature value is 35 ℃, the outdoor environment temperature is 40 ℃, and the first threshold value is 2 ℃, then the opening degree of the second air duct 3 opened by the wind shield 4 is adjusted to be 50% when the indoor environment temperature value is less than 25 ℃; and when the indoor environment temperature is more than or equal to 25 ℃, the opening degree of the second air duct 3 opened by the wind shield 4 is adjusted to 100 percent.
For example, when the air conditioner operates in a refrigeration working condition, the target temperature value is adjusted to be 25 ℃, the first temperature value is 25 ℃, the second temperature value is 29 ℃, the third temperature value is 35 ℃, the outdoor environment temperature is 33 ℃, and the first threshold value is 2 ℃, then the opening degree of the second air duct 3 opened by the wind shield 4 is adjusted to be 50% when the indoor environment temperature value is less than 29 ℃ in the embodiment; and when the indoor environment temperature is more than or equal to 29 ℃, the opening degree of the second air duct 3 opened by the air baffle 4 is adjusted to be 100 percent.
For another example, when the air conditioner operates in a refrigeration working condition, the adjustment target temperature value is 24 ℃, the first temperature value is 25 ℃, the second temperature value is 29 ℃, the third temperature value is 35 ℃, the outdoor environment temperature is 36 ℃, and the first threshold value is 2 ℃, then the opening degree of the second air duct 3 opened by the wind shield 4 is adjusted to be 50% when the indoor environment temperature value is less than 26 ℃ in the embodiment; when the indoor environment temperature is more than or equal to 26 ℃, the opening degree of the wind shield 4 for opening the second air duct 3 is adjusted to be 100%.
For example, when the air conditioner operates in a heating working condition, the target temperature is adjusted to be 26 ℃, the fourth temperature value is 22 ℃, the fifth temperature value is 17 ℃, the sixth temperature value is 4 ℃, the outdoor environment temperature value is 0 ℃, and the second threshold value is 3 ℃, then the opening degree of the second air duct 3 opened by the wind shield 4 is adjusted to be 50% when the indoor environment temperature is higher than 22 ℃ in the embodiment; when the indoor environment temperature is less than 22 ℃, the opening degree of the wind shield 4 for opening the second air duct 3 is adjusted to be 100%.
For example, when the air conditioner operates in a heating working condition, the target temperature is adjusted to be 24 ℃, the fourth temperature value is 22 ℃, the fifth temperature value is 17 ℃, the sixth temperature value is 4 ℃, the outdoor environment temperature value is 3 ℃, and the second threshold value is 3 ℃, then the opening degree of the second air duct 3 opened by the wind shield 4 is adjusted to be 50% when the indoor environment temperature is higher than 21 ℃; and when the indoor environment temperature is lower than 21 ℃, the opening degree of the second air duct 3 opened by the air baffle 4 is adjusted to be 100%.
For example, when the air conditioner operates in a heating working condition, the target temperature is adjusted to be 22 ℃, the fourth temperature value is 22 ℃, the fifth temperature value is 17 ℃, the sixth temperature value is 4 ℃, the outdoor environment temperature value is 10 ℃, and the second threshold value is 3 ℃, then the opening degree of the second air duct 3 opened by the wind shield 4 is adjusted to be 50% when the indoor environment temperature is greater than 17 ℃; and when the indoor environment temperature is less than 17 ℃, the opening degree of the second air duct 3 opened by the wind shield 4 is adjusted to be 100%.
Specifically, the control method is executed once every first time interval to ensure that the wind deflector 4 can be timely controlled to open the second air duct 3 to a proper opening degree, for example, once every 10 minutes.
Specifically, an opening degree of 100% indicates that the wind deflector 4 fully opens the second air duct 3, and an opening degree of 50% indicates that the wind deflector 4 covers 50% of the cross-sectional area of the second air duct 3 and leaves 50% of the cross-sectional area open.
Optionally, in other embodiments of the present invention, the opening degree of the second air duct 3 may be divided into a plurality of levels, and a plurality of determination levels are set for all three determination conditions, which is beneficial to adjusting the opening degree of the second air duct 3 more sensitively and accurately, and is beneficial to improving the matching degree between the opening degree of the second air duct 3 and the indoor temperature adjustment condition; of course, one of the plurality of opening levels of the second duct 3 may be fully closed.
In order to verify the noise reduction effect of the second air duct 3 opening degree adjustment according to the embodiment, a comparison experiment is performed, wherein one scheme of the comparison experiment is that the opening degree of the second air duct 3 of the air conditioner is 50%, another scheme of the comparison experiment is that the opening degree of the second air duct 3 of the air conditioner is 100%, the two schemes of the comparison experiment are operated in the same environment with the indoor environment temperature value meeting the first condition, other experiment conditions including the rotating speed of the centrifugal fan 1 are the same in the two schemes of the comparison experiment, then the operating noise of the air conditioner of the two schemes is detected in a standard noise room, the noise spectrum of the air conditioner with the second air duct 3 opening degree of 100% is obtained as shown in fig. 4, and the vibration noise spectrum of the air conditioner with the second air duct 3 opening degree of 50% is obtained as shown in fig..
As can be seen from fig. 4 and 5, the total operating noise value of the air conditioner with the opening of the second air duct 3 being 100% is 48.0dB, and the noise peak value is 32.2 dB; the total running noise value of the air conditioner with the opening of the second air duct 3 being 50% is 44.6dB, and the noise peak value is 24.8 dB; compared with the air conditioner with the opening of the second air duct 3 being 100%, the total noise value of the air conditioner with the opening of the second air duct 3 being 50% is reduced by 3.4dB, and the noise peak value is reduced by 7.4 dB.
As can be seen from the above, on the one hand, the first air duct 2 and the second air duct 3 are provided in the embodiment, and when the indoor environment temperature value is not in the temperature range where the human body feels comfortable, the opening degree of the second air duct 3 is adjusted to be fully opened, which is beneficial to increasing the air outlet volume of the air conditioner under the condition, and is convenient for rapidly improving the temperature of the indoor environment with a larger air volume; on the other hand, when the condition of reducing the opening degree of the second air duct 3 is met, the indoor environment temperature value is adjusted to a temperature range which is comfortable for human bodies to feel, at the moment, the requirement of the user on the adjustment rate of the indoor environment temperature value is reduced, and because the air conditioner of the embodiment is provided with the first air duct 2 and the second air duct 3, the opening degree of the second air duct 3 is reduced, the air outlet volume of the air conditioner cannot be reduced too much, so that the reduction of the opening degree of the second air duct 3 does not cause obvious adverse effect on the user body feeling; in addition, the opening degree of the second air duct 3 is reduced, so that the running noise of the air conditioner is reduced, the adverse effect of the running of the air conditioner on the normal work and life of a user is reduced, and the user experience is improved; particularly, the air conditioner of the present embodiment generally has a short time when the second air duct 3 is fully opened (for rapidly adjusting the room temperature), and is normally operated when the second air duct 3 is half opened, so that the arrangement of the present embodiment is beneficial to reducing the noise of the air conditioner during most of the operation period.
When the air conditioner is operated in a cooling condition, if the ambient temperature is too high, for example, higher than 40 ℃, at this time, in order to rapidly cool the indoor environment, the user often sets the adjustment target temperature value to be far lower than the comfortable temperature, for example, if the adjustment target temperature value is set to 18 c, and the opening degree of the second air path 3 is controlled solely according to the first condition, it may cause a situation where the second air path 3 is in a fully open state for a long time, so that the second air duct 3 is still in the fully open state after the indoor environment temperature value is in the human body comfortable temperature interval, which causes the air conditioner to operate in a state with larger noise for a long time, therefore, the second condition is set in the embodiment, the first temperature value of the second condition is preset, the air conditioner is not set by a user, so that the condition that the air conditioner runs for a long time and has larger running noise due to the fact that the user sets an excessively low adjusting target temperature value can be avoided; in a similar way, the second condition is set when the air conditioner operates in the heating working condition in the embodiment, and the fourth temperature value of the second condition is preset, but not set by the user, so that the air conditioner can be prevented from operating for a long time under the condition of larger operating noise because the user sets an excessively high adjustment target temperature value, the influence of the operating noise of the air conditioner and the indoor environment temperature on the user can be better balanced, and the operating noise of the air conditioner can be reduced as early as possible under the condition of not influencing the experience of the user on the indoor environment temperature.
Specifically, the first temperature value and the fourth temperature value may be preset according to power (matching) of the air conditioner and a temperature at which a user feels comfortable, the first temperature value is generally a higher temperature value within a range at which the user feels comfortable, the fourth temperature value is generally a lower temperature value within a range at which the user feels comfortable, and the larger the power of the air conditioner is, the larger the value of the first temperature value is, the smaller the value of the fourth temperature value is. Taking the air conditioner as an example, when the power of the air conditioner is larger, the faster the refrigeration rate of the air conditioner is, the larger the value of the first temperature value is set, so that on one hand, the air conditioner can meet the condition of reducing the opening of the second air duct 3 as early as possible during operation so as to reduce the operation noise of the air conditioner as early as possible, and on the other hand, because the power of the air conditioner is larger, the air conditioner can still adjust the indoor environment temperature value to the adjustment target temperature value at a relatively fast rate after reducing the opening of the second air duct 3; therefore, the operation noise of the air conditioner is further reduced as early as possible under the condition that the user experience of the indoor environment temperature is not influenced; in the same way, when the air conditioner operates in the heating working condition, the operation noise of the air conditioner is further reduced as early as possible under the condition that the user experience of the indoor environment temperature is not influenced.
Furthermore, when the air conditioner operates in a refrigeration working condition, under the condition that parameters such as power and air outlet volume of the air conditioner are fixed, if the outdoor environment temperature value is lower, the rate of leakage of the cold energy of the indoor environment to the outdoor environment is lower, and the rate of improvement of the indoor environment temperature is higher, so that the third condition is set for controlling the refrigeration operation of the air conditioner, and the second temperature value higher than the first temperature value is set for the third condition, so that the operation noise of the air conditioner is further reduced as early as possible under the condition that the experience of a user on the indoor environment temperature is not influenced; similarly, when the air conditioner operates in the heating working condition, the fifth temperature value lower than the fourth temperature value is set, so that the operation noise of the air conditioner can be further reduced as early as possible under the condition that the user experience of the indoor environment temperature is not influenced.
In this embodiment, the first condition, the second condition, and the third condition are used together as the determination condition for controlling the opening degree of the second air duct 3, alternatively, in other embodiments of the present invention, only one or two of the first condition, the second condition, and the third condition may be used as the determination condition for controlling the opening degree of the second air duct 3, for example, only the first condition is used as the determination condition for controlling the opening degree of the second air duct 3, when the first condition is met, the opening degree of the second air duct 3 is adjusted to 50%, when the first condition is not met, the opening degree of the second air duct 3 is adjusted to 100%, and the first condition can accurately reflect the adjustment requirement of the user on the indoor environment temperature under a general condition; for example, the first condition and the second condition are used together as the determination condition for controlling the opening degree of the second air duct 3, and when any one or both of the first condition and the second condition is satisfied, the opening degree of the second air duct 3 is adjusted to 50%, otherwise, the opening degree of the second air duct 3 is adjusted to 100%.
Optionally, in other embodiments of the present invention, the adjustment control on the centrifugal fan 1 may also be added, and the adjustment control on the operating frequency of the compressor may also be added, for example, the gear of the centrifugal fan 1 is adjusted down and the operating frequency of the compressor is adjusted down at the same time of decreasing the opening degree of the second air duct 3, so that when the indoor environment temperature value is adjusted to the more comfortable temperature range, it is further beneficial to reduce the noise and power consumption of the air conditioner, and it is beneficial to avoid the air conditioner from causing an excessive influence on the normal life of the user.
