Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the present invention and should not be construed as limiting the present application.
An air conditioner and a control method and apparatus thereof according to an embodiment of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a method for controlling an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the method for controlling an air conditioner according to the embodiment of the present application specifically includes the following steps:
and S101, acquiring the current outdoor environment temperature.
Generally, a temperature sensor is used to obtain the current outdoor ambient temperature. The temperature sensor may be, but is not limited to, an outdoor unit of the air conditioner.
S102, identifying a target temperature interval to which the outdoor environment temperature belongs.
Specifically, the outdoor environment temperature is obtained, and the outdoor environment temperature is compared with a preset temperature interval, so that the target temperature interval to which the outdoor environment temperature belongs can be identified. For example, the preset temperature range is 0-20 ℃ and 20-30 ℃, and when the outdoor environment temperature is 25 ℃, the target temperature range of the outdoor environment temperature can be determined to be 20-30 ℃.
And S103, correcting the set temperature of the air conditioner and the rotating speed of a fan in the air conditioner according to the target temperature interval.
Specifically, the target temperature interval is determined, the set temperature of the air conditioner and the rotating speed of the fan can be corrected, so that the set temperature and the rotating speed of the fan are adaptive to the current outdoor environment temperature, the influence of the outdoor environment temperature on the air conditioner is reduced, the indoor environment temperature adjusted by the air conditioner can be matched with the refrigeration or heating requirement of a user, and the user experience is improved.
As a possible implementation manner, the set temperature and the rotation speed of the fan are corrected by using the correction parameters, as shown in fig. 2, the method includes the following steps:
s201, acquiring a temperature correction parameter and a rotating speed correction parameter corresponding to a target temperature interval.
Optionally, in this embodiment, a first mapping relationship between the temperature interval and the temperature correction parameter and a second mapping relationship between the temperature interval and the rotation speed correction parameter are preset. And acquiring a target temperature interval to which the current outdoor environment temperature belongs, and inquiring the first mapping relation and the second mapping relation by using the target temperature interval to acquire the temperature correction parameter and the rotating speed correction parameter corresponding to the target temperature interval.
S202, correcting the set temperature according to the temperature correction parameter.
Specifically, the set temperature can be corrected according to the temperature correction parameter by acquiring the temperature correction parameter.
Alternatively, the set temperature may be corrected based on a mathematical relationship between a preset temperature correction parameter and the set temperature. For example, if the mathematical relationship between the temperature correction parameter and the set temperature is T1 ═ T0 ± n, where T1 is the set temperature after correction, T0 is the set temperature before correction, and n is the temperature correction parameter, then when the set temperature before correction is 24 ℃ and the temperature correction parameter is 1, the set temperature after correction is 25 ℃ or 23 ℃. The different temperature correction parameters may be discrete values or continuous values, and are not limited herein.
And S203, correcting the rotating speed of the fan according to the rotating speed correction parameter.
Specifically, the rotating speed of the fan can be corrected according to the rotating speed correction parameter obtained.
Optionally, different windshields in the wind turbine correspond to different rotational speed correction parameters, and each windshield corresponds to one rotational speed correction parameter. At this time, the rotating speed of the fan in different windshields can be corrected according to the preset mathematical relationship between the rotating speed correction parameter and the rotating speed corresponding to the windshields. For example, the mathematical relationship between the rotation speed correction parameter and the rotation speed corresponding to the highest windshield is W1 ═ W0 ± e, where W1 is the rotation speed corresponding to the highest windshield after correction, e is the rotation speed correction parameter, and W0 is the rotation speed corresponding to the highest windshield before correction, the rotation speed corresponding to the highest windshield before correction is 100r/S, and when the rotation speed correction parameter is 10, the rotation speed corresponding to the highest windshield after correction is 110r/S or 90 r/S; the correction mode of the rotation speed corresponding to other windshields is similar to the correction mode of the rotation speed corresponding to the highest windshield, and the details are not repeated herein. The different rotation speed correction parameters may be discrete values or continuous values, and are not limited herein.
Optionally, the rotation speed corresponding to the remaining windshield may be corrected by using the rotation speed corresponding to the corrected windshield.
As shown in fig. 3, the method comprises the following steps:
s301, identifying a target windshield corresponding to the rotating speed correction parameter, and correcting the rotating speed corresponding to the target windshield by using the rotating speed correction parameter.
Specifically, after the rotating speed correction parameter is obtained, a target windshield corresponding to the current rotating speed correction parameter is determined according to a preset corresponding relation between the rotating speed correction parameter and a windshield in the fan. And then, the rotating speed corresponding to the target windshield is corrected by using the rotating speed correction parameter, and for the correction mode, the windshield correction mode can be referred to, and the details are not repeated herein.
And S302, correcting the rotating speed corresponding to the residual windshield of the fan according to the corrected rotating speed corresponding to the target windshield.
Specifically, a mathematical relationship between the rotation speed corresponding to the target windshield and the rotation speeds corresponding to the remaining windshields may be set in advance; then, the rotational speed corresponding to the remaining windshield is corrected using the rotational speed corresponding to the corrected target windshield and a preset mathematical relationship. For example, the mathematical relationship between the rotation speed corresponding to the first windshield and the rotation speed corresponding to the second windshield is W11 ═ C × W12, where W11 is the rotation speed corresponding to the first windshield, C is a proportionality coefficient, and W12 is the rotation speed corresponding to the second windshield; and when the second windshield is the target windshield, substituting the corrected second windshield into the mathematical relation between the rotating speed corresponding to the first windshield and the rotating speed corresponding to the second windshield, so as to obtain the rotating speed corresponding to the corrected first windshield.
As another possible implementation manner, when the air conditioner is in the cooling mode, the set temperature and the rotation speed of the fan may be corrected according to whether the target temperature interval in which the outdoor environment temperature is located changes. As shown in fig. 4, the method comprises the following steps:
s401, recognizing that the air conditioner is in a cooling mode and the target temperature interval of the outdoor environment temperature is changed.
Specifically, whether the air conditioner is in the cooling mode may be identified according to a control instruction currently received by the air conditioner. For example, if the air conditioner currently receives a control command for cooling, it may be determined that the air conditioner is in the cooling mode, and if the air conditioner currently receives a control command for heating, it may be determined that the air conditioner is in the heating mode.
In addition, after the outdoor environment temperature is obtained, the current target temperature interval to which the current outdoor environment temperature belongs may be compared with the previous target temperature interval to which the previous outdoor environment temperature belongs. And if the current target temperature interval is different from the previous target temperature interval, identifying the target temperature interval transmission change of the outdoor environment.
S402, detecting and determining the increase of the target temperature interval where the outdoor environment temperature is located, and controlling to reduce the set temperature and increase the rotating speed of the fan.
Specifically, if the target temperature interval where the outdoor environment temperature is located rises, it indicates that the outdoor environment temperature is rising, the weather is hot, and the cold output needs to be increased, so that the rotating speed of the fan can be controlled to be increased. In addition, in order to enable the air conditioner to continue to output cooling energy, the set temperature may be controlled to be lowered.
And S403, detecting and determining that the target temperature interval where the outdoor environment temperature is located is reduced, and controlling to increase the set temperature and reduce the rotating speed of the fan.
Specifically, if the target temperature range where the outdoor environment temperature is located is reduced, it indicates that the outdoor environment temperature is being reduced, the weather is gradually cooled, and the cold output needs to be reduced, so that the rotation speed of the fan can be controlled to be reduced. In addition, the set temperature can be controlled to be increased so as to further reduce the cold output.
It should be noted that, in order not to affect the rest of the user, in this embodiment, when the rotation speed of the fan is adjusted, the rotation speed of the fan may be adjusted in the first preset range, so as to avoid the influence of noise generated by sudden increase of the rotation speed of the fan on the rest of the user. Further, in order to avoid that the set temperature is too low to affect the rest of the user, the set temperature may be adjusted in the second preset range.
As another possible implementation manner, when the air conditioner is in the heating mode, the set temperature and the rotation speed of the fan may also be corrected according to whether the target temperature interval in which the outdoor environment temperature is located changes. As shown in fig. 5, the method comprises the following steps:
s501, recognizing that the air conditioner is in a heating mode and the target temperature interval of the outdoor environment temperature is changed.
Specifically, whether the air conditioner is in the heating mode may be identified according to a control instruction currently received by the air conditioner. For example, if the air conditioner currently receives a control command for heating, it may be determined that the air conditioner is in the heating mode.
In addition, after the outdoor environment temperature is obtained, the current target temperature interval to which the current outdoor environment temperature belongs may be compared with the previous target temperature interval to which the previous outdoor environment temperature belongs. And if the current target temperature interval is different from the previous target temperature interval, identifying the target temperature interval transmission change of the outdoor environment.
S502, detecting and determining the increase of the target temperature interval where the outdoor environment temperature is located, and controlling to reduce the set temperature and the rotating speed of the fan.
Specifically, if the target temperature interval where the outdoor environment temperature is located is increased, it indicates that the outdoor environment temperature is increasing, and the weather is relatively warm, the heat output can be reduced, and therefore, the reduction of the rotation speed of the fan can be controlled. In addition, the set temperature can be controlled to be lowered to further reduce the heat output.
S503, detecting and determining that the target temperature interval where the outdoor environment temperature is located is reduced, and controlling to increase the set temperature and increase the rotating speed of the fan.
Specifically, if the target temperature range in which the outdoor environment temperature is located is decreased, it indicates that the outdoor environment temperature is decreasing, and the weather is cold, the heat output needs to be increased, and therefore, the rotation speed of the fan can be controlled to be increased. In addition, the set temperature can be controlled to be increased so as to ensure the continuous output of heat.
In some embodiments, before the set temperature of the air conditioner and the rotation speed of the fan in the air conditioner are corrected, it may be further detected and determined that a duration that the outdoor environment temperature is in the target temperature interval is greater than or equal to a preset duration, so as to determine that the outdoor environment temperature is a stable change, thereby determining a real outdoor environment condition.
In some embodiments, after the set temperature of the air conditioner and the rotating speed of the fan in the air conditioner are corrected, the fan in the air conditioner can be controlled according to the indoor environment temperature, so that the fan is prevented from continuously running, and electric energy is saved. As shown in fig. 6, the method comprises the following steps:
s601, acquiring the current indoor environment temperature.
In general, a current indoor ambient temperature is acquired by a temperature sensor installed indoors.
And S602, acquiring an absolute difference value between the indoor environment temperature and the corrected set temperature.
And S603, detecting and determining that the absolute difference value is within a preset range, and controlling the fan to be in a closed state.
Specifically, when the absolute difference between the indoor ambient temperature and the corrected set temperature is within the preset range, it indicates that the indoor ambient temperature reaches the temperature range set by the user at this time, that is, the current indoor ambient temperature meets the temperature required by the user, and therefore, at this time, the fan may be controlled to be in the off state.
And S604, detecting and determining that the absolute difference value is not in a preset range, and controlling the fan to be in an opening state.
Specifically, when the absolute difference between the indoor ambient temperature and the corrected set temperature is not within the preset range, it indicates that the indoor ambient temperature does not reach the temperature range set by the user at this time, that is, the current indoor ambient temperature does not meet the required temperature of the user, and therefore, at this time, the fan may be controlled to be in an on state to continue to adjust the indoor ambient temperature.
For convenience of understanding, a control method of the air conditioner in the present embodiment is explained by taking the air conditioner in the cooling mode as an example. As shown in fig. 7, 8 and 9, the air conditioner starts to cool for 24 hours, the temperature Ts set by the user starts to be 25 ℃, the windshield is the maximum windshield, the variation of the outdoor environment temperature T4 along with the starting time is shown in fig. 7, the variation of the revised set temperature Tm along with the starting time is shown in fig. 8, and the variation of the corrected fan rotation speed Rm along with the T4 is shown in fig. 9. For ease of understanding, T4, Tm, Rm are plotted on the abscissa with the turn-on time. When the air conditioner is started for cooling, the temperature T4 is 35 ℃, Tm is the temperature Ts set by a user to be 25 ℃, and the maximum fan rotating speed Rm of the air conditioner is the maximum leaving rotating speed Rd to be 1000 r/min. That is, Ts and Rd are not revised at the temperature, that is, the maximum wind speed value and the cold output set by the factory of the air conditioner are comfortable in the temperature range of 28-36 ℃.
At noon, the outdoor temperature rises to 43 ℃ and exceeds 36 ℃ for more than 2 hours. The outdoor temperature is high, the temperature is hot, and the user needs to increase the cold output. At this time, the air conditioner revises the set temperature and the rotating speed of the fan, revises Tm to 24 ℃ (namely Tm is 25 ℃ -1 ℃, wherein 1 ℃ is a temperature correction parameter, the mathematical relationship between Tm and Ts is Tm is Ts-1), and Rm is revised to 1100r/min (namely Rm is 1000r/min +100r/min is 1100r/min, wherein 100r/min is a rotating speed correction parameter, and the mathematical relationship between Rm and Rd is Rm is Rd +100), and the cold quantity is increased by increasing the air quantity; the set temperature of the air conditioner is reduced, so that the air conditioner can continuously output cold energy. In view of the increase of indoor noise caused by increasing the rotating speed of the fan, Rm can be increased by 100r/min appropriately; lowering the set temperature may cause the user to feel cold, and Tm is lowered by 1 ℃ as appropriate depending on the outdoor ambient temperature.
In the evening, when the outdoor environment temperature T4 returns to 35 ℃ from 43 ℃, Tm and Rm are restored to the original state, so that the phenomenon that the cold output is too large and a user feels cold is avoided.
The outdoor ambient temperature T4 continued to decrease to 27 c and below 28 c for more than 1 hour during the evening hours. The set temperature Ts is corrected to a corrected set temperature Tm of 26 ℃ (i.e., Tm 25+1 26 ℃), and the maximum fan rotation speed Rd is corrected to a corrected maximum fan rotation speed Rm of 900r/min (i.e., Rm 1000r/min-100r/min 900 r/min).
