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, acquiring indoor environment temperature in real time, and recording the operation time of the air conditioner in each operation state.
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 environment temperature can be detected in real time through a temperature sensor arranged indoors (such as on an indoor unit of the air conditioner), and the running time of the air conditioner in each running state can be recorded through a timer arranged in 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 PC (personal computer) and the like and a target temperature set by a user, and the acquiring unit is used for acquiring the indoor environment temperature and the running time of the air conditioner in each running state.
And S102, in the running process of the air conditioner, selecting a control rule for carrying out frequency reduction control or unloading control on the air conditioner according to the target temperature, the current indoor environment temperature, the running time of the air conditioner in the current running state and the indoor environment temperature corresponding to the starting and stopping running time of the air conditioner in the current running state.
The control rules comprise a first control rule and a second control rule, and the first control rule and the second control rule can be set according to needs. For example, for an inverter air conditioner, the first control rule may be that the rotational speed is reduced n0 every time the frequency down control is performed, and the second control rule may be that the rotational speed is reduced n1 every time the frequency down control is performed, and n0 > n 1. For a fixed speed air conditioner, the first control rule may be a reduction in displacement of air conditioner per unloading Q0, and the second control rule may be a reduction in displacement of air conditioner per unloading Q1, with Q0 > Q1.
S103, if the first control rule is selected, performing frequency reduction control or unloading control on the air conditioner according to the first control rule.
And S104, if the second control rule is selected, performing frequency reduction control or unloading control on the air conditioner according to the second control rule.
For example, after the user controls the air conditioner to start up through the remote controller, the user can set a first target temperature for refrigeration, such as 22 ℃, and the temperature sensor arranged on the indoor unit of the air conditioner can detect the indoor environment temperature in real time. In the operation process of the air conditioner, the analysis feedback unit shown in fig. 3 selects a control rule for performing down-conversion control or unloading control on the air conditioner according to the target temperature, the current indoor environment temperature, the operation time of the air conditioner in the current operation state, and the indoor environment temperature corresponding to the start-stop operation time of the air conditioner in the current operation state. If the first control rule is selected, the control unit performs frequency reduction control or unloading control on the air conditioner according to the first control rule so as to reduce the output capacity of the air conditioner or reduce the air displacement; if the second control rule is selected, the control unit performs down-conversion control or unloading control on the air conditioner according to the second control rule to reduce the output capacity of the air conditioner or reduce the air displacement.
Therefore, the method can reduce energy consumption while enabling the indoor environment temperature to meet the requirements of human bodies.
In some embodiments of the present invention, if a difference between the target temperature and the current indoor ambient temperature satisfies a down-conversion control or unloading control condition of the air conditioner, a first control rule is selected; if the difference value between the target temperature and the current indoor environment temperature does not meet the condition of frequency reduction control or unloading control of the air conditioner, judging whether the running time of the air conditioner in the current running state reaches the preset time or not; if the running time of the air conditioner in the current running state reaches the preset time, calculating the change rate of the indoor environment temperature in the running time according to the indoor environment temperature corresponding to the starting and stopping running time of the air conditioner in the current running state, and judging whether the change rate of the indoor environment temperature reaches the preset value or not; and if the change rate of the indoor environment temperature reaches a preset value, selecting a second control rule.
And if the difference between the target temperature and the current indoor environment temperature does not meet the condition of frequency reduction control or unloading control of the air conditioner, or if the running time of the air conditioner in the current running state does not reach the preset time, controlling the air conditioner to keep the current running state.
Specifically, when the air conditioner is operating in a certain state, if the absolute value of the difference between the target temperature and the current indoor environment temperature is smaller than the first preset temperature difference, the condition for controlling the air conditioner to perform down-conversion or unloading is met, and at this time, the control unit shown in fig. 3 performs down-conversion or unloading control on the air conditioner according to the first control rule. If the absolute value of the difference between the target temperature and the current indoor environment temperature is greater than or equal to the first preset temperature difference, the operation time of the air conditioner in the current operation state reaches the preset time T0, the temperatures corresponding to the starting and stopping time of T0 are T1 and T2, respectively, the change rate of the corresponding indoor environment temperature is | T2-T1|/T0, and | T2-T1|/T0 is greater than or equal to the preset value, the control unit shown in fig. 3 performs down-conversion control or unloading control on the air conditioner according to the second control rule.
The first preset temperature difference, the preset time and the preset value can be set according to needs, and if the value range of the first preset temperature difference is 3-5 ℃, the value range of the preset time is 5-30 min, and the value range of the preset value is 0.3-1 ℃/min.
In some embodiments of the present invention, if | T2-T1|/T0 is less than a preset value, the air conditioner is controlled to maintain the current operation state and the operation state is restarted.
Further, in some embodiments of the present invention, after performing down-conversion or unloading control on the air conditioner, it is further determined whether a difference between the target temperature and the current indoor environment temperature satisfies a shutdown condition of the air conditioner; if the difference between the target temperature and the current indoor environment temperature meets the shutdown condition of the air conditioner, controlling the air conditioner to be shut down; and if the difference between the target temperature and the current indoor environment temperature does not meet the shutdown condition of the air conditioner, controlling the air conditioner to keep the current running state, namely the state after frequency reduction or unloading, and recording the running time of the air conditioner in the current running state again.
Specifically, after the air conditioner is subjected to down-conversion or unloading control, in the process that the air conditioner operates in a state after down-conversion or unloading, if the absolute value of the difference between the target temperature and the current indoor environment temperature is smaller than the second preset temperature difference, the stop control condition of the air conditioner is met, and at this time, the control unit shown in fig. 3 controls the air conditioner to stop. And if the absolute value of the difference between the target temperature and the current indoor environment temperature is greater than or equal to the second preset temperature difference, the control unit controls the air conditioner to keep the current running state, returns to the judgment of the frequency reduction control or the unloading control, and restarts timing on the current running state.
In order to facilitate understanding of the control method of the air conditioner according to the embodiment of the present invention, the following description may be made with reference to fig. 3 and 4:
referring to 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 a first target temperature such as 22 ℃ and an operation mode set by a user, and the acquiring unit acquires the indoor environment temperature in real time. And then in the process of the air conditioner refrigerating/heating operation, the analysis feedback unit compares and analyzes the target temperature of the air conditioner and the current indoor environment temperature and generates a corresponding analysis result, and the control unit correspondingly controls the air conditioner according to the analysis result.
Specifically, referring to fig. 3 and 4, after the air conditioner is turned on, the analysis feedback module obtains the indoor ambient temperature T1 at the time of turning on. In the process that the air conditioner operates in the corresponding mode, the analysis feedback unit judges whether the difference between the target temperature and the indoor environment temperature is smaller than a first preset difference or not in real time, and if the difference between the target temperature and the indoor environment temperature is smaller than the first preset difference in preset time, the control unit performs frequency reduction control (variable frequency air conditioner)/unloading control (constant speed air conditioner) on the air conditioner according to a first control rule.
If the difference between the target temperature and the indoor environment temperature is always greater than or equal to a first preset difference when the running time of the air conditioner reaches a preset time T0, the analysis feedback unit obtains the indoor environment temperature T2 at the end moment of the preset time, and calculates the indoor environment temperature change rate | T2-T1|/T0 within the preset time T0. If the change rate is larger than or equal to the preset value, the control unit performs frequency reduction/unloading control on the air conditioner according to a second control rule. If the conversion rate is smaller than the preset value, the air conditioner is controlled to keep the current running state, the judgment of the frequency reduction/unloading control is returned, and the running state is restarted.
After the air conditioner is subjected to frequency reduction or unloading control, if the absolute value of the difference between the target temperature and the current indoor environment temperature is smaller than a second preset temperature difference, controlling the air conditioner to stop; otherwise, returning to the judgment of the frequency reduction/unloading control, and re-timing the running state after frequency reduction/unloading.
In some embodiments of the present invention, for the inverter air conditioner, when the control method of fig. 4 is adopted, the determination of the down-conversion control condition needs to be performed. The changes in the indoor ambient temperature after the cooling and heating operations of the air conditioner may be shown by solid lines in fig. 5 and 6, respectively. In contrast, fig. 5 and 6 also show the indoor ambient temperature change curves (dotted lines) after the cooling and heating operations of the air conditioner using the conventional control method shown in fig. 1, respectively. As can be seen from fig. 5 and 6, the method of the present invention has lower energy consumption than the conventional method.
In other embodiments of the present invention, for a constant speed machine, when the control method of fig. 4 is adopted, the determination of the unloading control condition is required. The changes in the indoor ambient temperature after the cooling and heating operations of the air conditioner may be shown by solid lines in fig. 7 and 8, respectively. In contrast, fig. 7 and 8 also show the indoor ambient temperature change curves (dotted lines) after the cooling and heating operations of the air conditioner using the conventional control method shown in fig. 1, respectively. As can be seen from fig. 7 and 8, the method of the present invention has lower energy consumption than the conventional method.
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.
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, the control rule for performing the frequency reduction control or the unloading control on the air conditioner is selected according to the target temperature, the current indoor environment temperature, the operation time of the air conditioner in the current operation state, and the indoor environment temperature corresponding to the start-stop operation time of the air conditioner in the current operation state, and the frequency reduction control or the unloading control is performed on the air conditioner according to the corresponding rule, so that the energy consumption is reduced while the indoor environment temperature meets the human body requirement.
