Based on the hardware architecture, the embodiment of the control method of the air conditioner is provided.
Referring to fig. 2, a flow chart of a first embodiment of a control method of an air conditioner according to the present invention includes:
step S10, acquiring indoor environment temperature;
in the present invention, the air conditioner refers to an air conditioner having an inverter compressor. When the air conditioner normally operates, the temperature sensor at the air inlet position of the panel of the indoor unit of the air conditioner can detect the indoor environment temperature in real time or at regular time.
Step S20, when the first difference between the indoor environment temperature and the set temperature is not in the first preset difference interval, adjusting the running frequency of the compressor;
when the air conditioner normally operates, comparing the acquired indoor environment temperature with the indoor temperature set by a user, and calculating a first difference value between the indoor environment temperature and the set temperature, wherein a first preset difference value interval is set by the user, for example, the first preset difference value interval is-2. And if the first difference value is not in the first preset difference value interval, adjusting the operating frequency of the compressor according to the relationship between the first difference value and the first preset difference value interval so as to meet the refrigerating/heating requirements of users.
Specifically, the air conditioner includes a cooling mode and a heating mode. And judging whether the first difference is larger than the maximum value of the first preset difference interval or not, judging the relation between the first difference and the minimum value of the first preset difference interval, and judging whether the first difference and the minimum value of the first preset difference interval have no precedence relation. For example, the first predetermined difference interval is-2 to 2. When in the cooling mode, for example, when the first difference is greater than 2, increasing the frequency of the compressor, and after the air conditioner runs for a preset time, increasing the frequency of the compressor to the running frequency corresponding to the set temperature; and when the first difference is less than-2, reducing the frequency of the compressor, and after the air conditioner runs for a preset time, reducing the frequency of the compressor to the running frequency corresponding to the set temperature. In the heating mode, when the first difference is greater than 2, reducing the frequency of the compressor, and after the air conditioner runs for a preset time, reducing the frequency of the compressor to the running frequency corresponding to the set temperature; and when the first difference is smaller than-2, increasing the frequency of the compressor, and after the air conditioner runs for a preset time, increasing the frequency of the compressor to the running frequency corresponding to the set temperature. And when the first difference value is between-2 and 2, maintaining the frequency of the compressor unchanged.
It should be noted that the operating frequency of the compressor may be adjusted according to the gear, or the operating frequency of the compressor may be adjusted according to a certain difference.
Step 30, obtaining the air outlet temperature;
when the air conditioner operates normally, a temperature sensor in an indoor unit of the air conditioner can detect the air outlet temperature of an air outlet of the air conditioner in real time or at regular time.
And step S40, when a second difference between the air outlet temperature and the preset air outlet temperature is not within a second preset difference interval, adjusting the rotating speed of the indoor fan.
The air conditioner compares the air outlet temperature with a preset air outlet temperature according to the acquired air outlet temperature of the air outlet of the air conditioner, wherein the preset air outlet temperature can be the temperature at which a human body feels comfortable, and for example, the temperature at which the human body feels comfortable is between 13 ℃ and 15 ℃ in the refrigeration condition according to big data statistics; under the condition of heating, the temperature for human body to feel comfortable is between 42 ℃ and 45 ℃. Or the preset outlet air temperature can also be a preset temperature corresponding to time according to the environment. And calculating a second difference between the outlet air temperature and the preset outlet air temperature, wherein a second preset difference interval is set by a user, for example, the second preset difference interval is-1. And comparing the second difference value with a second preset difference value interval, judging the relation between the second difference value and the second preset difference value interval, and adjusting the rotating speed of the indoor fan according to the relation between the second difference value and the second preset difference value interval. For example, when the air conditioner operates in the cooling mode, if a second difference between the outlet air temperature and the preset outlet air temperature is greater than the maximum value of a second preset difference interval, the rotating speed of the indoor fan is reduced, the outlet air temperature is close to the preset outlet air temperature, and the comfort of outlet air of the air conditioner is improved. It can be understood that, when the second difference is within the second preset difference interval, the rotating speed of the indoor fan is not changed.
In the technical scheme that this embodiment provided, the air conditioner acquires indoor ambient temperature earlier, and according to ambient temperature and the relation between the preset temperature, adjust the operating frequency of compressor, satisfy user's basic refrigeration/heating demand, then adjust the rotational speed of indoor fan according to the relation that the air-out temperature of air conditioner air outlet and preset air-out temperature see only that, cause the great phenomenon of air-out temperature change when avoiding appearing adjusting the wind speed, make air-out temperature satisfy user's demand, improve the travelling comfort of air conditioner.
Referring to fig. 2, fig. 2 is a second embodiment of the method for controlling an air conditioner according to the present invention, and based on the first embodiment, after the step S20, the method for controlling an air conditioner includes:
and step S50, operating for a preset time according to the adjusted operating frequency.
And after the operation is carried out for the preset time according to the adjusted operation frequency, executing step S30, namely obtaining the air outlet temperature.
When the first difference is not within the first preset difference interval, the running frequency of the compressor is increased or reduced, each set temperature corresponds to the running frequency of the set compressor, after the running frequency of the compressor is adjusted, the running frequency of the compressor can reach the set running frequency corresponding to the set temperature, the running of the compressor is preset for a long time, the air outlet temperature of the air conditioner can be stabilized, and then the air outlet temperature is obtained. For example, when the air conditioner is in a cooling mode, if the first difference is greater than or equal to the maximum value of the preset difference interval, the operating frequency of the compressor is increased until the operating frequency of the compressor corresponding to the set temperature, then the compressor operates for a period of time, for example, 30 minutes or 20 minutes, at the operating frequency corresponding to the set temperature, so that the outlet air temperature of the air conditioner can be stabilized, and then the outlet air temperature of the air conditioner is obtained, so that the outlet air temperature is finely adjusted in the subsequent process of adjusting the rotating speed of the indoor fan, and the phenomenon that the outlet air temperature changes too much is avoided.
In the technical scheme that this embodiment provided, the air conditioner adjusts the operating frequency of compressor according to indoor ambient temperature to it is long when running for one section and predetermineeing, make the frequency of compressor can reach the operating frequency of the compressor that the settlement temperature corresponds, at the in-process of follow-up regulation indoor fan rotational speed, keep the operating frequency of compressor unchangeable, through carrying out for the regulation to the air-out temperature, avoid the air-out temperature change of air conditioner too big to cause the discomfort to the human body, improve the travelling comfort of air conditioner.
Referring to fig. 4, fig. 4 is a third embodiment of the method for controlling an air conditioner according to the present invention, and based on the second embodiment, after step S40, the method for controlling an air conditioner further includes:
step S60, controlling the indoor fan to operate for a preset time according to the adjusted rotating speed;
and returning to the step S30, namely acquiring the outlet air temperature.
In this embodiment, when the second difference is not within the second preset difference interval, the rotating speed of the indoor fan is increased or decreased, so as to adjust the outlet air temperature. After the rotating speed of the indoor fan is adjusted, the indoor fan runs for a period of time according to the preset time, then the air outlet temperature is obtained, and the rotating speed of the indoor fan is adjusted according to the relation between the new second difference and the second preset difference interval until the new second difference is within the range of the second preset difference interval or the rotating speed of the indoor fan reaches the maximum rotating speed or the minimum rotating speed. For example, after the rotation speed of the indoor fan is adjusted, the indoor fan operates for a preset time period, for example, two minutes, and then the step of obtaining the outlet air temperature is performed. The air outlet temperature of the air conditioner is micro-regulated, so that the air outlet temperature of the air conditioner is close to the preset air outlet temperature as much as possible, namely the temperature at which a human body feels comfortable, and the comfort of the air conditioner is improved.
It should be noted that the rotating speed of the indoor fan is adjusted to make the outlet air temperature of the air outlet of the air conditioner approach the preset outlet air temperature, and when the second difference is within the range of the second preset difference, the rotating speed of the indoor fan is maintained unchanged.
In the technical scheme provided by this embodiment, the air conditioner operates for a preset time after adjusting the rotating speed of the indoor fan. And then returning to the step of obtaining the air outlet temperature again, and adjusting the rotating speed of the indoor fan according to the newly obtained second difference value, so that the rotating speed of the indoor fan is gradually increased or decreased, the phenomenon that the air outlet temperature is changed too much due to the change of the air speed is avoided, the air outlet temperature is gradually increased or gradually decreased, and the comfort of the air conditioner is improved.
Referring to fig. 5, fig. 5 is a fourth embodiment of a control method of an air conditioner, and the step S40 includes:
step S41, determining whether the second difference is within the second preset difference interval;
judging whether the second difference value is within a second preset difference value interval or not, and if the second difference value is within the second preset difference value interval, maintaining the rotating speed of the indoor fan unchanged; and if the second difference is not within the second preset difference interval, adjusting the rotating speed of the indoor fan. The step of determining whether the second difference is within the second preset difference interval specifically includes determining whether the second difference is greater than a maximum value of the second preset difference interval and determining that the second difference is smaller than a minimum value of the second difference interval, and it should be noted that there is no precedence relationship between determining whether the second difference is greater than the maximum value of the second preset difference interval and determining that the second difference is smaller than the minimum value of the second difference interval.
Step S42, if the second difference is not within the second preset difference interval, obtaining an adjustment coefficient of the rotating speed;
when the second difference is not within the second preset difference interval, obtaining an adjustment coefficient of the rotating speed of the indoor fan, and specifically obtaining an operation mode of the air conditioner; and acquiring the adjusting coefficient according to the running mode. Because the operation modes of the air conditioner are different, the means for adjusting the rotating speed of the indoor fan according to the relation between the second difference and the second preset difference interval are different, namely the adjusting coefficients are different.
For example, in the cooling mode, the second difference interval is-1 to 1, and if the second difference is greater than 1, the rotating speed of the indoor fan is reduced, so that the current rotating speed is Nn＝(1-k)*Nn-1In which N isn-1The rotating speed of the indoor fan at the previous time, the k value is an adjustment coefficient, and the value range of k is 0.1-0.9. Detecting the air outlet temperature of the air conditioner again after every two seconds, and if the second difference value is-1, keeping the rotating speed of the indoor fan unchanged; and if the second difference is still larger than 1, reducing k until the rotating speed of the indoor fan is reduced to the lowest rotating speed value. If the second difference is less than-1, increasing the rotating speed of the indoor fan to make the current rotating speed be Nn＝(1+k)*Nn-1In which N isn-1The rotating speed of the indoor fan at the previous time, the k value is an adjustment coefficient, and the value range of k is 0.1-0.9. Detecting the air outlet temperature of the air conditioner again after every two seconds, and if the second difference value is-1, keeping the rotating speed of the indoor fan unchanged; and if the second difference is still less than-1, increasing k until the rotating speed of the indoor fan is increased to the maximum rotating speed value.
For example, in the heating mode, the second difference interval is-1 to 1, and when the second difference is greater than 1, the rotating speed of the indoor fan is increased, so that the current rotating speed is Nn＝(1+k)*Nn-1In which N isn-1The rotating speed of the indoor fan at the previous time, the k value is an adjustment coefficient, and the value range of k is 0.1-0.9. Detecting the air outlet temperature of the air conditioner again after every two seconds, and if the second difference value is-1, keeping the rotating speed of the indoor fan unchanged; and if the second difference is still larger than 1, increasing k until the rotating speed of the indoor fan is increased to the maximum rotating speed value. If the second difference is less than-1, reducing the rotating speed of the indoor fan to enable the current rotating speed to be Nn＝(1-k)*Nn-1In which N isn-1The rotating speed of the indoor fan at the previous time, the k value is an adjustment coefficient, and the value range of k is 0.1-0.9. Detecting the air outlet temperature of the air conditioner again after every two seconds, and if the second difference value is-1, keeping the rotating speed of the indoor fan unchanged; if the second difference is still less than-1, reducing k until the rotating speed of the indoor fan is increased to the lowest rotating speed value
And step S43, adjusting the rotating speed of the indoor fan according to the adjusting coefficient.
In this embodiment, it is determined whether the second difference is within a second preset difference interval, and if the second difference is not within the second preset difference interval, the rotation speed of the indoor fan is adjusted, and in the process of adjusting the rotation speed of the indoor fan, an adjustment coefficient of the rotation speed of the indoor fan is first obtained, and the rotation speed of the indoor fan is adjusted according to the adjustment coefficient. For example, when the air conditioner is in a cooling mode, the rotating speed of the indoor fan is adjusted to be Nn-1After the preset time period, for example, two minutes, is operated according to the adjusted rotating speed, the current indoor fan rotating speed is adjusted according to the outlet air temperature obtained again, and the current indoor fan rotating speed is NnIf the second difference is larger than the maximum value of the preset second preset difference interval, the rotating speed N of the indoor fan is currently setn＝(1-k)*Nn-1Wherein the value of k is an adjustment coefficient, and the value range of k is 0.1-0.9. In this embodiment, the air conditioner adjusts the rotational speed of indoor fan according to the adjustment coefficient for the rotational speed of indoor fan is and increases step by step or subtracts step by step, and it is big to avoid the change that the wind speed regulation leads to the air-out temperature too fast, makes the air-out temperature more easily accepted by the user, thereby improves the travelling comfort of air conditioner.
Referring to fig. 6, fig. 6 is a fifth embodiment of a control method of an air conditioner, and based on the first embodiment and the second embodiment, the step S40 includes:
step S41, determining whether the second difference is within the second preset difference interval;
step S44, if the second difference value is not within the second preset difference value interval, obtaining an adjusting value corresponding to the second difference value;
and step S45, adjusting the rotating speed of the indoor fan according to the adjusting value.
In this embodiment, in the process of adjusting the rotation speed of the indoor fan, a second difference between the outlet air temperature and the preset outlet air temperature is calculated first, whether the second difference is within a second preset difference interval is judged, and when the second difference is not within the second preset difference interval, a corresponding adjustment value is obtained according to a mapping relationship between the second difference and the adjustment value, which can be understood that the adjustment value and the second difference are in one-to-one correspondence; or the regulating value corresponds to the difference interval, the difference interval corresponds to the regulating value, and the regulating value corresponding to the difference interval is obtained according to the difference interval in which the second difference is positioned. And then adjusting the rotating speed of the indoor fan according to the obtained adjusting value.
In the technical scheme that this embodiment provided, the air conditioner is according to the rotational speed of the regulating value regulation room fan that corresponds with the second difference for the air conditioner can adjust the rotational speed of room fan according to actual conditions, thereby furthest's air-out temperature's of air conditioner requirement improves user experience.
