Detailed Description
Reference will now be made in detail to embodiments of the present invention, 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 invention and are not to be construed as limiting the invention.
An air conditioner, a control method thereof, and an apparatus thereof according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a control method of an air conditioner according to an embodiment of the present invention. As shown in fig. 2, the control method of the air conditioner includes the following steps:
s101, after the air conditioner is started, acquiring a target temperature set by a user, and acquiring indoor environment temperature and indoor environment humidity in real time.
Specifically, the user may send a power-on command to the air conditioner through a remote controller of the air conditioner, an APP of the mobile terminal, a client of the PC, and the like, to control the power-on of the air conditioner and set a target temperature of the air conditioner. The indoor ambient temperature can be detected in real time by a temperature sensor arranged indoors (such as on an indoor unit of an air conditioner), and the indoor ambient humidity can be detected in real time by a humidity sensor arranged indoors (such as on the indoor unit of the air conditioner).
For example, as shown in fig. 3, the air conditioner may be provided with a receiving unit, an obtaining unit, an analyzing and feeding back unit and a control unit. The receiving unit is used for receiving a starting instruction sent by a remote controller, a mobile terminal, a Personal Computer (PC) and the like and a target temperature set by a user, and the acquiring unit is used for acquiring indoor environment temperature and indoor environment humidity in real time.
And S102, judging whether the current indoor environment humidity is less than the preset humidity.
The value of the preset humidity can be set according to needs, and the value range of the preset humidity can be 60% -70%, such as 65%.
And S103, if the current indoor environment humidity is greater than or equal to the preset humidity, controlling the air conditioner to operate in a preset maximum dehumidification output or maximum dehumidification mode.
And S104, if the current indoor environment humidity is less than the preset humidity, controlling the air conditioner to refrigerate according to the preset maximum output capacity.
Specifically, after the air conditioner is turned on, if the current indoor environment humidity is greater than or equal to a preset humidity, such as 65%, the control unit shown in fig. 3 may directly control the air conditioner to operate in a preset maximum dehumidification output or maximum dehumidification mode; if the current indoor environment humidity is less than the preset humidity, for example, 65%, the control unit shown in fig. 3 may directly control the air conditioner to perform cooling according to the preset maximum output capacity.
And S105, judging whether the difference value between the current indoor environment temperature and the target temperature is smaller than a first preset temperature difference or not in the refrigerating operation process of the air conditioner.
The first preset temperature difference can be set according to needs, and can be a value within 3-5 ℃.
And S106, if the difference value between the current indoor environment temperature and the target temperature is smaller than the first preset temperature difference, performing frequency reduction control on the air conditioner.
Specifically, when the air conditioner is subjected to down-conversion control, the down-conversion control rule may be preset, and if the down-conversion condition is satisfied every time, the rotation speed of the compressor is controlled to be reduced by the preset rotation speed n 0.
In this embodiment, if the difference between the current indoor ambient temperature and the target temperature is greater than or equal to the first preset temperature difference, the air conditioner is controlled to maintain the current operation state.
For example, after the user controls the air conditioner to start up through the remote controller, the user can set a target temperature for refrigeration, such as 22 ℃, the temperature sensor arranged on the air conditioner indoor unit can detect the indoor environment temperature in real time, and the humidity sensor arranged on the air conditioner indoor unit can detect the indoor environment humidity in real time. Before the air conditioner cools, the analysis feedback unit shown in fig. 3 may first determine whether the humidity of the indoor environment is less than a preset humidity, for example, 65%, and if so, the control unit shown in fig. 3 may control the air conditioner to directly enter a dehumidification mode and operate in a preset maximum dehumidification output or maximum dehumidification mode; and if not, the control unit carries out refrigeration according to the preset maximum output capacity. During the cooling operation of the air conditioner, the analysis feedback unit shown in fig. 3 determines whether the difference between the current indoor ambient temperature and the target temperature is smaller than a first preset temperature difference. If so, the control unit performs frequency reduction control on the air conditioner to reduce the refrigeration output and reduce the energy consumption. If not, the control unit controls the air conditioner to keep the current operation state.
Therefore, the method can achieve a good cooling effect in a short time, reduce energy consumption and save energy.
In some embodiments of the present invention, after controlling the air conditioner to operate in the preset maximum dehumidification output or maximum dehumidification mode, when the indoor environment humidity is less than the preset humidity, the air conditioner is controlled to switch to the cooling mode to operate, and the air conditioner is controlled to cool according to the preset maximum output capacity.
Specifically, after the air conditioner operates in a preset maximum dehumidification output or maximum dehumidification mode, the indoor environment humidity is gradually reduced, when the indoor environment humidity is less than the preset humidity, the control unit shown in fig. 3 can control the air conditioner to exit the dehumidification mode and switch to the refrigeration mode, and control the air conditioner to refrigerate according to the preset maximum output capacity, so that rapid cooling can be realized.
In other embodiments of the present invention, after controlling the air conditioner to operate in a preset maximum dehumidification output or maximum dehumidification mode, the dehumidification operation time of the air conditioner is recorded, and when the dehumidification operation time reaches a preset time, the air conditioner is controlled to switch to the refrigeration mode to operate, and the air conditioner is controlled to perform refrigeration according to a preset maximum output capacity.
The preset time can be set according to needs such as the position and the weather condition, and can be taken within 5-30 min, such as 15 min.
Specifically, after the dehumidifying operation time of the air conditioner reaches a preset time, for example, 15min, the control unit shown in fig. 3 may control the air conditioner to exit the dehumidifying mode, switch to the cooling mode, and cool according to a preset maximum output capacity, so as to achieve rapid cooling.
It should be noted that, after the air conditioner is controlled to operate in the preset maximum dehumidification output or maximum dehumidification mode, if the indoor environment humidity is still greater than the preset humidity when the dehumidification operation time of the air conditioner reaches the preset time, for example, 15min, the control unit may control the air conditioner to exit the dehumidification mode, switch to the refrigeration mode, and perform refrigeration according to the preset maximum output capacity. And if the indoor environment humidity is reduced to the preset temperature and the dehumidifying operation time of the air conditioner does not reach the preset time, the control unit can control the air conditioner to exit the dehumidifying mode, switch to the refrigerating mode and refrigerate according to the preset maximum output capacity.
In some embodiments of the present invention, after performing the frequency reduction control on the air conditioner, it is determined whether a difference between the current indoor ambient temperature and the target temperature is smaller than a second preset temperature difference, where the second preset temperature difference is smaller than the first preset temperature difference. And if the difference value between the current indoor environment temperature and the target temperature is less than the second preset temperature difference, controlling the air conditioner to stop. And if the difference value between the current indoor environment temperature and the target temperature is greater than or equal to the second preset temperature difference, returning to the judgment of the air conditioner for carrying out frequency reduction control.
In this embodiment, as shown in fig. 3, when the air conditioner receives the power-on signal through the receiving unit, the control unit controls the air conditioner to be powered on. After the air conditioner is started, the receiving unit receives the target temperature set by a user, and the acquiring unit acquires the indoor environment temperature and the indoor environment humidity in real time. And then the analysis feedback unit compares and analyzes the target temperature, the indoor environment temperature and the indoor environment humidity and generates a corresponding analysis result, and the control unit correspondingly controls the air conditioner according to the analysis result.
Specifically, in an embodiment of the present invention, referring to fig. 3 and 4, the analysis feedback unit first determines whether the indoor ambient humidity sampled at the time of starting up is less than a preset humidity, for example, 50%. If so, the control unit controls the air conditioner to refrigerate according to the preset maximum output capacity so as to realize the rapid reduction of the indoor environment temperature; if not, the control unit controls the air conditioner to operate in a preset maximum dehumidification output or maximum dehumidification mode, timing is started, and the acquisition unit acquires the dehumidification operation time.
Further, the analysis feedback unit judges whether the dehumidification operation time reaches a preset time, such as 15min, if so, the control unit controls the air conditioner to switch to a refrigeration mode for operation, and controls the air conditioner to refrigerate according to a preset maximum output capacity.
In the refrigerating operation process of the air conditioner, the analysis feedback module unit judges whether the difference value between the current indoor environment temperature and the target temperature is smaller than a first preset temperature difference, such as 4 ℃, in real time or at regular intervals. If so, the control unit performs frequency reduction control on the air conditioner according to a preset frequency reduction rule so as to reduce the refrigeration output capacity and reduce the energy consumption. If not, the control unit controls the air conditioner to keep the current operation state.
After the air conditioner operates in a frequency reduction mode, the analysis feedback unit further judges whether a shutdown condition is met according to the difference between the current indoor environment temperature and the target temperature, namely whether the difference between the current indoor environment temperature and the target temperature is smaller than a second preset temperature difference, such as 1 ℃. If yes, the control unit controls the air conditioner to stop. If not, the control unit controls the air conditioner to keep the current running state, runs according to the difference value of the target temperature and the room temperature, and then enters the frequency reduction running condition judgment to circulate until the shutdown condition is met.
In another embodiment of the present invention, referring to fig. 3 and 5, the analysis feedback unit first determines whether the indoor ambient humidity sampled at the time of starting up is less than a preset humidity, such as 50%. If so, the control unit controls the air conditioner to refrigerate according to the preset maximum output capacity so as to realize the rapid reduction of the indoor environment temperature; if not, the control unit controls the air conditioner to operate in a preset maximum dehumidification output or maximum dehumidification mode.
Further, after the air conditioner is in dehumidification operation, the analysis feedback unit judges whether the indoor environment humidity is reduced to a preset humidity of 65%, if so, the control unit controls the air conditioner to be switched to a refrigeration mode to operate, and controls the air conditioner to refrigerate according to a preset maximum output capacity.
In the refrigerating operation process of the air conditioner, the analysis feedback module unit judges whether the difference value between the current indoor environment temperature and the target temperature is smaller than a first preset temperature difference, such as 4 ℃, in real time or at regular intervals. If so, the control unit performs frequency reduction control on the air conditioner according to a preset frequency reduction rule so as to reduce the refrigeration output capacity and reduce the energy consumption. If not, the control unit controls the air conditioner to keep the current operation state.
After the air conditioner operates in a frequency reduction mode, the analysis feedback unit further judges whether a shutdown condition is met according to the difference between the current indoor environment temperature and the target temperature, namely whether the difference between the current indoor environment temperature and the target temperature is smaller than a second preset temperature difference, such as 1 ℃. If yes, the control unit controls the air conditioner to stop. If not, the control unit controls the air conditioner to keep the current running state, runs according to the difference value of the target temperature and the room temperature, and then enters the frequency reduction running condition judgment to circulate until the shutdown condition is met.
In some embodiments of the present invention, referring to fig. 3, if the air conditioner has a WiFi internet of things function, the operations such as on-off control, target temperature setting and the like can be performed through the APP end, the PC end and the like of the mobile phone, and then the operations are implemented through the receiving unit, the obtaining unit, the analysis feedback unit and the control unit.
In an embodiment of the present invention, the control method of the air conditioner according to the embodiment of the present invention is adopted, that is, after the air conditioner is started, the humidity of the indoor environment is determined first, and if the humidity is relatively high, the operation of dehumidifying first and then cooling is performed, and the change curve of the temperature of the indoor environment after the cooling operation is shown as the solid line in fig. 6. Accordingly, in the case where the air conditioner, the operating environment of the air conditioner, and the target temperature set by the user are the same, the indoor ambient temperature variation curve using the conventional air conditioner cooling control method is shown by a dotted line in fig. 6. It can be seen that the method of the present invention can achieve the target temperature T3 for the first time at time T1, and the conventional method achieves the target temperature T3 for the first time at time T2, that is, compared with the conventional air conditioner refrigeration control method, the control method of the present invention can achieve a better cooling effect in a shorter time, and the user experience is good. In addition, before the time t0, the temperature drop of the method is smaller than that of the traditional method, so the method has good energy-saving effect.
Alternatively, the function of the analysis feedback unit shown in fig. 3 may also be implemented by the cloud platform shown in fig. 3.
In summary, according to the control method of the air conditioner in the embodiment of the present invention, after the air conditioner is turned on, the humidity of the indoor environment is determined first, and if the humidity is higher, the dehumidification is performed first, and then the refrigeration is performed, so that the refrigeration is continued after the humidity meets a certain condition, thereby achieving a better cooling effect in a shorter time, and when the difference between the temperature of the indoor environment and the target temperature meets the frequency reduction condition or the shutdown condition, the frequency reduction control is performed on the air conditioner or the air conditioner is controlled to be shut down, thereby reducing energy consumption and achieving energy saving.
