It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.
The invention provides a control method of an air conditioner, please refer to FIG. 1, comprising:
step S100, when the air conditioner is in refrigeration operation, the indoor environment temperature T is obtained 1 And indoor environmental humidity RH 1 ；

Step S300, when the indoor environment humidity RH 1 Not equal to the optimal energy-saving humidity RH 2 When the indoor unit of the air conditioner is controlled to change the rotating speed, the indoor environment humidity RH is caused 1 Equal to the optimal energy-saving humidity RH 2 。
The control method of the air conditioner is suitable for the air conditioner in the refrigeration mode, and firstly, the indoor environment is acquiredTemperature T 1 And indoor environmental humidity RH 1 The method comprises the steps of carrying out a first treatment on the surface of the Then judging the indoor environment humidity RH 1 Whether or not to be equal to the indoor environment temperature T 1 Corresponding to the preset optimal energy-saving humidity RH 2 The method comprises the steps of carrying out a first treatment on the surface of the When the indoor environment humidity RH 1 Not equal to the optimal energy-saving humidity RH 2 When the indoor unit of the air conditioner is controlled to change the rotating speed, the indoor environment humidity RH is caused 1 Equal to the optimal energy-saving humidity RH 2 . The indoor environment humidity RH can be realized by adjusting the running rotating speed of the fan 1 Always is the optimal energy-saving humidity RH 2 Thereby enabling the air conditioner to be in the optimal energy-saving state.
In particular, when the compressor frequency is constant, the indoor environment temperature T in the room 1 And the indoor environment humidity RH in the room when the outdoor outside environment temperature is unchanged 1 The control is mainly performed by the rotating speed of the fan. When the rotation speed of the fan is reduced, the evaporation temperature is reduced, the air conditioner has poor refrigerating effect and good dehumidifying effect, and when the rotation speed of the inner fan is increased, the air conditioner has good refrigerating effect and poor dehumidifying effect.
Specifically, the control method of the air conditioner further comprises the following steps: acquiring a set temperature T 2 The method comprises the steps of carrying out a first treatment on the surface of the Judging the set temperature T 2 And indoor ambient temperature T 1 A relationship between; wherein when T 1 <T 2 And indoor environment humidity RH 1 Not equal to the optimal energy-saving humidity RH 2 When the indoor unit of the air conditioner is controlled to change the rotating speed, the indoor environment humidity RH is caused 1 Equal to the optimal energy-saving humidity RH 2 The method of (1) comprises: when the indoor environment humidity RH 1 Less than optimal energy-saving humidity RH 2 When the air conditioner is stopped, the air conditioner is controlled; when the indoor environment humidity RH 1 Is greater than or equal to the optimal energy-saving humidity RH 2 And when the fan is controlled to run at a rotating speed reduced.
Wherein, the user uses the remote controller to set T in the using process of the air conditioner 2 When T 1 <T 2 And RH (RH) 1 ＜RH 2 At this time, the room needs to be warmed up and the dehumidifying amount is reduced, so that the air conditioner is controlled to stop running; when T is 1 <T 2 And RH (RH) 1 ≥RH 2 In the time-course of which the first and second contact surfaces,at this time, the temperature of the room needs to be raised, the dehumidifying amount is increased, the refrigerating capacity needs to be reduced, and the dehumidifying amount is increased, and at this time, the rotating speed of the air conditioner fan is reduced to achieve the aim.
Specifically, the control method of the air conditioner further comprises the following steps: acquiring a set temperature T 2 And the temperature T of the evaporator of the air conditioner 3 The method comprises the steps of carrying out a first treatment on the surface of the According to the indoor environment temperature T 1 And indoor environmental humidity RH 1 Calculating the corresponding dew point temperature T 4 The method comprises the steps of carrying out a first treatment on the surface of the Judging the set temperature T 2 And indoor ambient temperature T 1 A relationship between; wherein when T1 is more than or equal to T2 and the indoor environment humidity RH 1 Not equal to the optimal energy-saving humidity RH 2 When the indoor unit of the air conditioner is controlled to change the rotating speed, the indoor environment humidity RH is caused 1 Equal to the optimal energy-saving humidity RH 2 The method of (1) comprises: when the indoor environment humidity RH 1 Less than optimal energy-saving humidity RH 2 When the fan is controlled to rotate at an increased speed; when the indoor environment humidity RH 1 Is greater than or equal to the optimal energy-saving humidity RH 2 When the fan is controlled to operate at the maximum rotation speed and the dew point temperature T is judged 4 And the temperature T of the evaporator 3 A relationship between; when T is 3 ≥T 4 When the temperature of the air blower is controlled to be lower than the rotating speed, the dew point temperature T is judged again after the preset time 4 And the temperature T of the evaporator 3 The relation between them, repeating the steps until T 3 <T 4 。
In practice, it may be according to T 3 And T is 4 To judge the dehumidifying effect of the air conditioner, when T 3 <T 4 The air conditioner dehumidifies, and the larger the temperature difference is, the larger the dehumidification amount is; when T is 3 ≥T 4 At this time, the air conditioner dehumidifying amount is zero. Specifically, when T1 is equal to or greater than T2 and RH 1 ＜RH 2 When the room needs to be cooled and the dehumidifying amount is reduced, the refrigerating capacity needs to be increased, and the dehumidifying amount is reduced, and at the moment, the rotating speed of the air conditioner fan is increased to achieve the aim; when T1 is greater than or equal to T2 and RH 1 ≥RH 2 At this time, the room needs to be cooled and the dehumidifying amount is increased, the refrigerating capacity needs to be increased, and the dehumidifying amount is increased, and at this time, the fan operation speed of the air conditioner is firstly operated according to the highest speed, and the T is synchronously detected 3 When T 3 ≥T 4 The running rotating speed of the fan is continuously reduced, and after the rotating speed is reduced, T is reduced 3 Reduce, detect once T after presetting duration 3 And T 4 Repeating the above operation until T 3 <T 4 And the dehumidification is continued while the temperature is reduced.
In particular, when the indoor environment humidity RH 1 Is greater than or equal to the optimal energy-saving humidity RH 2 When the fan is controlled to run at a reduced rotating speed, the method comprises the following steps: when the indoor environment humidity RH 1 Is greater than or equal to the optimal energy-saving humidity RH 2 And when the fan is controlled to operate at the lowest operating rotation speed. The lowest running speed is the lowest gear running speed of the fan, namely the fourth running speed. Such an arrangement allows the fastest attainment of the indoor ambient humidity RH 1 Equal to the optimal energy-saving humidity RH 2 Improving the energy-saving effect.
In particular, when the indoor environment humidity RH 1 Less than optimal energy-saving humidity RH 2 When the fan is controlled to run at the increased rotating speed, the method comprises the following steps: when the indoor environment humidity RH 1 Less than optimal energy-saving humidity RH 2 And when the fan is controlled to operate at the highest operating rotating speed. The highest running rotating speed is the highest gear running rotating speed of the fan, namely the first running rotating speed. Such an arrangement allows the fastest attainment of the indoor ambient humidity RH 1 Equal to the optimal energy-saving humidity RH 2 Improving the energy-saving effect.
Specifically, the fan has a multi-gear operation rotating speed, and the multi-gear operation rotating speed is sequentially reduced; when T is 3 ≥T 4 When the temperature of the air blower is controlled to be lower than the rotating speed, the dew point temperature T is judged again after the preset time 4 And the temperature T of the evaporator 3 The relation between them, repeating the steps until T 3 <T 4 The method of (1) comprises: when T is 3 ≥T 4 When the temperature of the air conditioner is lower than the preset temperature, the running speed of the fan is controlled to be reduced by one gear, and the dew point temperature T is judged again after the preset time 4 And the temperature T of the evaporator 3 The relation between them, repeating the steps until T 3 <T 4 。
In particular, when T 3 ≥T 4 The running speed of the fan is reduced by one gear, and the speed is reducedPost-rotation T 3 Decrease, detect once T after a preset period of time (5 minutes) 4 And T 3 If not satisfy T 3 <T 4 The running speed of the fan is continuously reduced by one gear so as to enable T to be realized by gradually reducing the speed of the fan 3 <T 4 And the dehumidification is continued while the temperature is reduced.
Specifically, the multi-speed operating speeds include a first operating speed, a second operating speed, a third operating speed, and a fourth operating speed; the first running speed is 1400r/min, the second running speed is 1200r/min, the third running speed is 1000r/min, and the fourth running speed is 800r/min. Such an arrangement can meet the regulation of indoor temperature and indoor humidity.
Optionally, the preset time period is 5min. Such an arrangement ensures the temperature T of the evaporator 3 And (3) stability.
In the specific implementation, the optimal humidity range of the human body is corresponding to each temperature. According to the big data, the optimal humidity ranges corresponding to different temperatures are shown in table 1, for example, when the ambient temperature is 23 ℃, the humidity which is most comfortable for human body feeling is 70% to 73%. Through experimental tests, when the temperature in the room is reduced to 23 ℃ and the humidity is reduced to 73%, the power consumption is 2.6 ℃ at the temperature of 30 ℃ at the inner side of the room and the humidity of 80% and the temperature of 35 ℃ at the outer side of the room; when the humidity was reduced to 70%, the power consumption was 2.8 ℃. Specific test data can be seen in table 2. As can be seen from Table 2, the more the humidity is lowered, the greater the power consumption is. From the above, the optimum energy-saving humidity corresponding to different temperatures can be obtained from tables 1 and 2, as shown in table 3.
