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:
s101, acquiring a first moment when the current rotating speed of the indoor fan is reduced to a target rotating speed.
Generally, the time required for an indoor fan to be raised or lowered from one gear to another gear is often pre-calibrated in an air conditioner. Because different wind gears of the indoor fan in the air conditioner correspond to different rotating speeds, and the wind gears of the indoor fan and the rotating speeds of the indoor fan are changed cooperatively, namely when the wind gears are changed, the rotating speeds are also changed, and therefore, the time required by the gear increase or decrease is the time required by the rotating speed increase or decrease corresponding to the gear.
After a control instruction for controlling the air conditioner to downshift is received, the downshift time calibrated in advance is inquired according to the target gear of the air conditioner to downshift and the current gear of the air conditioner, so that the time required by the current downshift can be determined, and the time required by the indoor fan to decrease from the current rotating speed to the target rotating speed is further determined. Then, the current time is added with the time required by the indoor fan to reduce from the current rotating speed to the target rotating speed, so that the first time when the indoor fan reduces from the current rotating speed to the target rotating speed can be determined.
For example, the time required for the pre-calibrated indoor fan to decrease from the third gear to the first gear is 10min, and the time required for the rotating speed of the indoor fan to decrease from the rotating speed corresponding to the third gear to the rotating speed corresponding to the first gear is also 10 min; after a control instruction for reducing the indoor fan from the third gear to the first gear is received, if the current time is two points in the afternoon, the first time when the rotating speed of the indoor fan is reduced from the rotating speed corresponding to the third gear to the rotating speed corresponding to the first gear is two tenths of a second.
And S102, acquiring a second moment when the running frequency of the compressor in the air conditioner is reduced from the current rotating speed to the target frequency corresponding to the target rotating speed.
Generally, the time required by the compressor for frequency reduction is calibrated in advance in the air conditioner, so that after a control instruction for controlling the air conditioner to downshift is received, the frequency reduction time of the pre-calibrated compressor is inquired according to a target gear of the air conditioner for downshift and a current gear of the air conditioner, that is, the time required by the current frequency reduction can be determined, and the frequency reduction time required by the compressor when the indoor fan is reduced from the current rotating speed to the target rotating speed is further determined. And then, adding the current time and the frequency reduction time to determine a second time when the operating frequency of the compressor is reduced from the current rotating speed of the indoor fan to the target frequency corresponding to the target rotating speed.
For example, when the indoor fan is lowered from the third gear to the first gear, the time required for the compressor to reduce the frequency is calibrated in advance to be 8min, and after the control instruction for lowering the indoor fan from the third gear to the first gear is received, if the current time is two points in the afternoon, it can be determined that the second time when the operating frequency corresponding to the rotating speed of the compressor is lowered from the third gear to the target frequency corresponding to the target rotating speed of the first gear is two points in the eighth.
S103, controlling the indoor fan and the compressor to enable the first time to be later than or equal to the second time.
Specifically, in the downshifting process of the indoor fan, the speed of reducing the rotating speed of the indoor fan is far greater than the speed of reducing the frequency of the compressor, so that when the rotating speed of the indoor fan is reduced to the target rotating speed, the operating frequency of the compressor is not reduced to the target frequency, at the moment, the compressor operates at the frequency higher than the target frequency, the current flow of the refrigerant in the air conditioner is greater than the flow of the refrigerant required when the indoor fan operates at the target rotating speed, and the excessive refrigerant can impact parts such as pipelines in the air conditioner, so that abnormal sound is generated. Therefore, in this embodiment, after the first time and the second time are obtained, the indoor fan and the compressor are controlled, so that the first time is later than or equal to the second time, thereby the operating speed of the indoor fan is reduced to the target speed while the operating frequency of the compressor is reduced to the target frequency, or the operating speed of the indoor fan is reduced to the target speed after the operating frequency of the compressor is reduced to the target frequency, so that the operating speed of the indoor fan can be matched with the operating frequency of the compressor, thereby avoiding the occurrence of the phenomenon of refrigerant abnormal sound caused by the mismatching of the operating speed of the indoor fan and the operating frequency of the compressor, namely solving the problem of refrigerant abnormal sound caused by the high operating frequency of the compressor due to the low operating speed of the indoor fan.
Optionally, when the first time is controlled to be later than or equal to the second time, the speed of decreasing the rotation speed of the indoor fan and the speed of decreasing the frequency of the compressor may be controlled such that the first time is later than or equal to the second time; the time when the indoor fan starts to slow down may be, but is not limited to, the same as the time when the compressor starts to slow down. As shown in fig. 2, the method comprises the following steps:
s201, performing speed reduction control on the indoor fan to obtain the speed reduction speed of the indoor fan.
Generally, when the indoor fan is subjected to speed reduction control, the speed reduction speed of the indoor fan at the time can be obtained according to a preset speed reduction speed.
S202, performing frequency reduction control on the compressor to obtain the frequency reduction speed of the compressor.
Generally, when performing the frequency reduction control on the compressor, the frequency reduction speed of the compressor at that time may be obtained according to a pre-calibrated frequency reduction speed.
And S203, controlling the speed reduction speed to be less than or equal to the frequency reduction speed.
Specifically, after the speed reduction speed of the indoor fan and the frequency reduction speed of the compressor are obtained, the speed reduction speed can be controlled to be smaller than or equal to the frequency reduction speed, so that the first time is later than or equal to the second time. For example, when the acquired reduction speed is a and the acquired reduction speed is B, a ≦ B may be controlled.
Optionally, when the first time is controlled to be later than or equal to the second time, the indoor fan may be controlled to intermittently reduce the speed, and the compressor is controlled to continuously reduce the frequency, so that the first time is later than or equal to the second time; the time when the indoor fan starts to slow down may be, but is not limited to, the same as the time when the compressor starts to slow down. For example, when the first moment is earlier than the second moment, controlling the indoor fan to stop reducing the speed and controlling the compressor to continue reducing the frequency; and when the first time is later than or equal to the second time, controlling the indoor fan to start to reduce the speed and controlling the compressor to continue to reduce the frequency, so that the first time is later than or equal to the second time.
Optionally, when the first time is controlled to be later than or equal to the second time, the time when the compressor starts to reduce the frequency may be controlled to be earlier than the time when the indoor fan starts to reduce the speed, so that the first time is later than or equal to the second time; and the time interval between the time of starting the frequency reduction of the compressor and the time of starting the speed reduction of the indoor fan is greater than or equal to the time interval between the first time and the second time.
Optionally, after the indoor fan and the compressor are controlled and the first time is later than or equal to the second time, the indoor fan may be controlled to perform speed reduction to the target rotation speed at the current speed reduction speed, and the compressor may be controlled to perform frequency reduction to the target frequency at the current frequency reduction speed.
To sum up, the technical solution in the embodiment of the present application at least has the following technical effects or advantages:
1. in the downshifting process of the indoor fan in the air conditioner, the first moment when the indoor fan is controlled to be reduced to the target rotating speed is later than or equal to the second moment when the compressor is controlled to be reduced to the target frequency corresponding to the target rotating speed, so that the running rotating speed of the indoor fan can be matched with the running frequency of the compressor, and the phenomenon of refrigerant abnormal sound caused by mismatching of the running rotating speed of the indoor fan and the running frequency of the compressor is avoided.
2. The speed reduction speed of the indoor fan is controlled to be smaller than or equal to the frequency reduction speed of the compressor, so that the first moment when the indoor fan is reduced to the target rotating speed can be later than or equal to the second moment when the compressor is reduced to the target frequency corresponding to the target rotating speed.
3. By controlling the indoor fan to intermittently reduce the speed and controlling the compressor to continuously reduce the frequency, the first moment when the indoor fan is reduced to the target rotating speed can be later than or equal to the second moment when the compressor is reduced to the target frequency corresponding to the target rotating speed.
4. The time when the compressor starts to reduce the frequency is controlled to be earlier than the time when the indoor fan starts to reduce the speed, so that the first time when the indoor fan reduces to the target rotating speed can be later than or equal to the second time when the compressor reduces to the target frequency corresponding to the target rotating speed.
