Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a frequency control method of an air conditioner, which judges whether to control the frequency-limited operation of the air conditioner according to the indoor humidity detected by a humidity sensor on an air conditioning system. When the air conditioner is in refrigeration operation, the indoor humidity has direct influence on the generation of condensed water, so that whether the condensed water can be generated or not can be accurately predicted according to the humidity, and the frequency-limited operation of the air conditioner is controlled in time to prevent the generation of the condensed water.
The air conditioners can be of various types, and can comprise an on-hook machine, a cabinet machine, a ceiling machine, a window machine, a mobile air conditioner and an embedded air conditioner according to installation modes; according to the working principle, the device can comprise a frequency converter and a fixed frequency converter; the use environment may include a household air conditioner and a commercial air conditioner. The following air conditioner will be described by taking an outdoor unit and an indoor unit, which are separately provided, as an example.
As shown in fig. 1, the air conditioner may include an indoor unit 110, an outdoor unit 120, and a refrigerant circulation circuit formed by the indoor unit 110 and the outdoor unit 120. The indoor unit 110 may include an indoor heat exchanger 111 and an indoor fan 112; the outdoor unit 120 may include a compressor 121, an outdoor heat exchanger 122, an outdoor fan 123, a four-way valve 124, and the like. The refrigerant pipes of the indoor unit 110 and the outdoor unit 120 are further provided with a throttle valve 130. An air outlet of the compressor 121 is connected to a first interface of the four-way valve 124, a second interface of the four-way valve 124 is connected to one end of the outdoor heat exchanger 122, the other end of the outdoor heat exchanger 122 is connected to one end of the indoor heat exchanger 111 through the throttle valve 130, and the other end of the indoor heat exchanger 111 is connected to a return air inlet of the compressor 121.
When the air conditioner operates in a refrigeration mode, the compressor 121 compresses a refrigerant and then discharges a high-pressure steam refrigerant, and the refrigerant flows through the outdoor heat exchanger, and meanwhile outdoor air sucked by an outdoor fan flows through the outdoor heat exchanger to exchange heat for the high-pressure steam refrigerant in the outdoor heat exchanger, so that the high-pressure steam refrigerant is condensed into high-pressure liquid; the high-pressure liquid enters the indoor heat exchanger through the throttle valve and is evaporated at a corresponding low pressure to absorb ambient heat, and meanwhile, the indoor fan continuously sucks air into the indoor heat exchanger for heat exchange and sends the air which is cooled after heat exchange into the room. Therefore, the indoor air continuously and circularly flows, and the aim of reducing the indoor humidity is fulfilled. It is understood that when the air conditioner is operated in a cooling mode, the outdoor heat exchanger may also be referred to as a condenser and the indoor heat exchanger may also be referred to as an evaporator. The refrigerant circulation loop when the air conditioner operates in the heating mode is just opposite to the refrigerant circulation loop when the air conditioner operates in the cooling mode, and the outdoor heat exchanger can be called an evaporator, and the indoor heat exchanger can be called a condenser.
Therefore, the air conditioner further includes: a humidity sensor 140 and a controller 150; the humidity sensor 140 is configured to obtain an indoor environment humidity RH1 within a first preset time when a compressor of the air conditioner is turned on and operates; and after the compressor of the air conditioner operates for a second preset time, acquiring the indoor environment humidity RH 2. The controller 150 is configured to control the frequency-limited operation of the compressor according to the humidity RH1 and the humidity difference between the humidity RH1 and the humidity RH 2.
Specifically, the humidity sensor 140 is installed at an air return opening of the indoor unit, and is used for detecting the indoor environment humidity. Of course, the humidity sensor 140 can be installed at other locations in the room, such as on the cabinet of the indoor unit or on other devices, such as a remote controller. The controller 150 may be an independently provided control device, or may be a functional module disposed on the air conditioner electronic control board. The controller 150 receives the indoor ambient humidity detected by the humidity sensor 140 at different periods of the operation of the air conditioner compressor, accurately predicts the generation of condensed water according to the indoor ambient humidity, and timely controls the air conditioner to operate at a limited frequency to prevent the condensed water in advance.
Because air condition compressor operation can take place corresponding change at the indoor ambient humidity of different periods, if indoor ambient humidity is great at first, then whether satisfy the preset condition according to the change volume of indoor ambient humidity in the operation process, if unsatisfied, then the prediction can produce the condensation water, control the air conditioner in advance and carry out the operation of frequency limiting. If the indoor environment humidity is small at first, but the indoor environment humidity does not drop but rises during the operation of the air conditioner, and the raised environment humidity exceeds a preset humidity value, condensation water is predicted to be generated, and the air conditioner is controlled to operate in a frequency-limited mode in advance. Therefore, in the embodiment of the present invention, the humidity sensor 140 obtains the humidity RH1 during the first preset time when the compressor is turned on and operates, and obtains the humidity RH2 after the compressor operates for the second preset time, and the controller 150 controls the frequency of the compressor according to the difference between the humidity RH1, the humidity RH1, and the humidity RH 2. The second preset time is the time counted after the compressor is started and operates for the first preset time.
The above control rule is set according to the condition of the condensed water generated due to the influence of the ambient humidity during the operation of the air conditioner, and it is needless to say that an appropriate control rule may be set according to other conditions due to the influence of the ambient humidity.
Specifically, embodiments of the present invention will preset a first humidity threshold. The first humidity threshold value is set according to the prediction standards of the condensed water under different indoor environment humidity within a period of time when the air conditioner compressor is started. For example, in the embodiment of the present invention, the first humidity threshold is 65%, that is, the prediction standard for the condensed water is different between the indoor ambient humidity greater than or equal to 65% and the indoor ambient humidity less than 65%. It is to be understood that the present invention is not limited to the first humidity threshold value comprising only one value, and that multiple values may be set to correspond to the prediction standard for dew condensation water at different indoor ambient humidity.
According to the embodiment of the invention, whether the frequency-limited operation of the air conditioner is controlled or not is judged according to the indoor humidity detected by the humidity sensor on the air conditioning system. When the air conditioner is in refrigeration operation, the indoor humidity has direct influence on the generation of condensed water, so that whether the condensed water can be generated or not can be accurately predicted according to the humidity, and the frequency-limited operation of the air conditioner is controlled in time to prevent the generation of the condensed water.
In addition, after the first humidity threshold value is set, a prediction standard suitable for the actual use environment and the use time can be selected according to the actual use environment and the use time of the air conditioner. For example, in a certain area, when the humidity of all the years is greater than the first humidity threshold, the prediction standard of the condensed water under the indoor environment humidity greater than or equal to the first humidity threshold can be directly selected for air conditioning control; during a certain month of use, when the local humidity is less than the first humidity threshold, the prediction criterion of the condensed water at the indoor ambient humidity less than the first humidity threshold can be directly selected for air conditioning control.
In one embodiment, the controller 150 is configured to: judging whether the humidity RH1 is greater than or equal to a first preset humidity threshold value; when the humidity RH1 is greater than or equal to the first humidity threshold, judging whether the humidity difference between the humidity RH1 and the humidity RH2 is less than or equal to a second preset humidity threshold; and when the humidity difference between the humidity RH1 and the humidity RH2 is less than or equal to a second preset humidity threshold value, setting the maximum operating frequency of the compressor of the air conditioner to be a preset operating frequency.
Specifically, the first humidity threshold value is 65%. And acquiring indoor ambient humidity RH1 in a first preset time when the compressor is started and operated. The first predetermined time may take a value of 10 minutes. During the 10 minutes, the humidity sensor 140 may acquire the humidity only once and take the humidity as the humidity RH 1; it is also possible to obtain the humidity RH1 by periodically obtaining several times and then averaging the humidity obtained by several times. When the acquired humidity RH1 is greater than or equal to 65%, the humidity sensor 140 acquires the indoor ambient humidity RH2 after the compressor operates for the second preset time. The second preset time may be 30 minutes, that is, the compressor is turned on and operates for 40 minutes. After the compressor has been running for 30 minutes, the humidity sensor 140 will acquire the indoor ambient humidity RH 2. It is understood that, in order to avoid the malfunction caused by a detection error, the embodiment of the present invention may continuously obtain the humidity several times, and then average the humidity to obtain the accurate indoor ambient humidity RH 2.
When the humidity RH1 is greater than or equal to 65%, the controller 150 calculates a humidity difference Δ RH between the humidity RH1 and the humidity RH2 as RH1-RH2, and determines whether the humidity difference Δ RH is less than or equal to a second preset humidity threshold, which is 5%. That is, when Δ RH is less than or equal to 5%, it indicates that the humidity change is not obvious during the operation of the air conditioner, so if the air conditioner continues to operate in the current state, the probability of the occurrence of condensed water of the air conditioner is very high, and therefore, the maximum operation frequency of the compressor of the air conditioner is set as the preset operation frequency, for example, 50 Hz. Namely, when the air conditioner determines that the frequency of the compressor is 60Hz according to the temperature difference between the indoor humidity and the set humidity, the final frequency of the compressor is 50Hz due to frequency-limited operation; assuming that the air conditioner determines that the compressor frequency is 40Hz according to the temperature difference between the indoor humidity and the set humidity, the final compressor frequency is 40Hz due to the frequency-limited operation.
After the air conditioner is frequency limited, the frequency limiting time may be controlled, for example, 30 minutes. Namely, after the air conditioner is operated for 30 minutes in a frequency limiting mode, the normal work of the compressor is recovered. In addition, after the frequency limitation is performed on the air conditioner, whether to quit the frequency limitation control can be determined according to the change of the indoor environment humidity. The method specifically comprises the following steps: the humidity sensor 140 acquires the indoor ambient humidity after limiting the frequency of the air conditioner, and is denoted as RH 3. The controller 150 is further configured to: and when the humidity difference between the humidity RH3 and the humidity RH1 is greater than or equal to a third preset humidity threshold value, the normal operation of the compressor of the air conditioner is resumed. In this embodiment, the value of the third predetermined humidity threshold is 10%. Namely, after the frequency-limited operation of the compressor is performed, when the drop amount of the indoor ambient humidity RH3 relative to the indoor ambient humidity RH1 obtained within a period of time when the compressor is started to operate is greater than or equal to 10%, the normal operation of the compressor of the air conditioner is recovered.
It can be understood that after the frequency limiting control is performed on the compressor, the humidity sensor 140 will periodically obtain the indoor ambient humidity RH3, and determine whether the frequency limiting control can be exited according to the humidity difference between the humidity RH3 and the humidity RH 1. And when the frequency limiting control can be quitted, the normal work of the compressor of the air conditioner is recovered.
In another embodiment, the controller 150 is further configured to: judging whether the humidity RH1 is smaller than a first preset humidity threshold value; when the humidity RH1 is less than the first preset humidity threshold, determining whether the humidity difference between the humidity RH2 and the humidity RH1 is greater than a fourth preset humidity threshold and the humidity RH2 is greater than or equal to a fifth preset humidity threshold; and when the humidity difference between the humidity RH2 and the humidity RH1 is greater than or equal to a fourth preset humidity threshold and the humidity RH2 is greater than or equal to a fifth preset humidity threshold, setting the maximum operating frequency of the compressor of the air conditioner to be a preset operating frequency.
Specifically, the value of the first preset humidity threshold is 65%. And acquiring indoor ambient humidity RH1 in a first preset time when the compressor is started and operated. The first predetermined time may take a value of 10 minutes. During the 10 minutes, the humidity sensor 140 may acquire the humidity only once and take the humidity as the humidity RH 1; it is also possible to obtain the humidity RH1 by periodically obtaining several times and then averaging the humidity obtained by several times. When the acquired humidity RH1 is greater than or equal to 65%, the humidity sensor 140 acquires the indoor ambient humidity RH2 after the compressor operates for the second preset time. The second preset time may be 30 minutes, that is, the compressor is turned on and operates for 40 minutes. After the compressor has been running for 30 minutes, the humidity sensor 140 will acquire the indoor ambient humidity RH 2. It is understood that, in order to avoid the malfunction caused by a detection error, the embodiment of the present invention may continuously obtain the humidity several times, and then average the humidity to obtain the accurate indoor ambient humidity RH 2.
When the humidity RH1 is less than 65%, the controller 150 calculates a humidity difference Δ RH between the humidity RH1 and the humidity RH2 as RH2-RH1, and determines whether the humidity difference Δ RH is greater than a fourth preset humidity threshold and the humidity RH2 is greater than a fifth preset humidity threshold. The fourth predetermined humidity threshold value is 20%, and the fifth predetermined humidity threshold value is 80%. That is, when Δ RH is greater than or equal to 20% and RH2 is greater than or equal to 80%, it indicates that the humidity is not decreased but increased during the operation of the air conditioner, and the increased humidity is greater than 80%, so that if the operation continues in the current state, the probability of the air conditioner generating condensed water is very high, and therefore, the maximum operation frequency of the compressor of the air conditioner is set to be the preset operation frequency, for example, 50 Hz. Namely, when the air conditioner determines that the frequency of the compressor is 60Hz according to the temperature difference between the indoor humidity and the set humidity, the final frequency of the compressor is 50Hz due to frequency-limited operation; assuming that the air conditioner determines that the compressor frequency is 40Hz according to the temperature difference between the indoor humidity and the set humidity, the final compressor frequency is 40Hz due to the frequency-limited operation.
After the air conditioner is frequency limited, the frequency limiting time may be controlled, for example, 30 minutes. Namely, after the air conditioner is operated for 30 minutes in a frequency limiting mode, the normal work of the compressor is recovered. In addition, after the frequency limitation is performed on the air conditioner, whether to quit the frequency limitation control can be determined according to the change of the indoor environment humidity. The method specifically comprises the following steps: the humidity sensor 140 acquires the indoor ambient humidity after limiting the frequency of the air conditioner, and is denoted as RH 3. The controller 150 is further configured to: and when the humidity difference between the humidity RH3 and the humidity RH1 is greater than or equal to a third preset humidity threshold value, the normal operation of the compressor of the air conditioner is resumed. In this embodiment, the value of the third predetermined humidity threshold is 10%. Namely, after the frequency-limited operation of the compressor is performed, when the drop amount of the indoor ambient humidity RH3 relative to the indoor ambient humidity RH1 obtained within a period of time when the compressor is started to operate is greater than or equal to 10%, the normal operation of the compressor of the air conditioner is recovered.
It can be understood that after the frequency limiting control is performed on the compressor, the humidity sensor 140 will periodically obtain the indoor ambient humidity RH3, and determine whether the frequency limiting control can be exited according to the humidity difference between the humidity RH3 and the humidity RH 1. And when the frequency limiting control can be quitted, the normal work of the compressor of the air conditioner is recovered.
Further, the controller 150 is further configured to: when the air conditioner is started and the compressor is started, the indoor environment humidity and the air conditioner running time are reset. In order to prevent the air conditioner from having a memory function, when the air conditioner is turned on and the compressor is started to operate, the controller 150 also clears the indoor environment humidity and the air conditioner operation time recorded in the memory so as to prevent the information recorded last time from being used for the current control.
Correspondingly, the invention further provides a frequency control method of the air conditioner, and the frequency control method is used for controlling the frequency of the compressor based on the air conditioner. As shown in fig. 2, the frequency control method of the air conditioner includes the steps of:
step S110, starting a compressor of the air conditioner and operating the compressor within a first preset time to obtain indoor environment humidity RH 1;
step S120, after the compressor of the air conditioner operates for a second preset time, obtaining indoor environment humidity RH 2;
and S130, controlling the frequency of the compressor according to the humidity RH1 and the humidity difference between the humidity RH1 and the humidity RH 2.
Because air condition compressor operation can take place corresponding change at the indoor ambient humidity of different periods, if indoor ambient humidity is great at first, then whether satisfy the preset condition according to the change volume of indoor ambient humidity in the operation process, if unsatisfied, then the prediction can produce the condensation water, control the air conditioner in advance and carry out the operation of frequency limiting. If the indoor environment humidity is small at first, but the indoor environment humidity does not drop but rises during the operation of the air conditioner, and the raised environment humidity exceeds a preset humidity value, condensation water is predicted to be generated, and the air conditioner is controlled to operate in a frequency-limited mode in advance. Therefore, in the embodiment of the present invention, the humidity sensor 140 obtains the humidity RH1 during the first preset time when the compressor is turned on and operates, and obtains the humidity RH2 after the compressor operates for the second preset time, and the controller 150 controls the frequency of the compressor according to the difference between the humidity RH1, the humidity RH1, and the humidity RH 2. The second preset time is the time counted after the compressor is started and operates for the first preset time.
According to the embodiment of the invention, whether the frequency-limited operation of the air conditioner is controlled or not is judged according to the indoor humidity detected by the humidity sensor on the air conditioning system. When the air conditioner is in refrigeration operation, the indoor humidity has direct influence on the generation of condensed water, so that whether the condensed water can be generated or not can be accurately predicted according to the humidity, and the frequency-limited operation of the air conditioner is controlled in time to prevent the generation of the condensed water.
Further, as shown in fig. 3, the step S130 includes:
step S201, judging whether the humidity RH1 is greater than or equal to a first preset humidity threshold value;
step S202, when the humidity RH1 is greater than or equal to a first humidity threshold, judging whether the humidity difference between the humidity RH1 and the humidity RH2 is less than or equal to a second preset humidity threshold;
and S203, when the humidity difference between the humidity RH1 and the humidity RH2 is less than or equal to a second preset humidity threshold value, setting the maximum operating frequency of the compressor of the air conditioner to be a preset operating frequency.
Specifically, the first humidity threshold value is 65%. And acquiring indoor ambient humidity RH1 in a first preset time when the compressor is started and operated. The first predetermined time may take a value of 10 minutes. During the 10 minutes, the humidity sensor 140 may acquire the humidity only once and take the humidity as the humidity RH 1; it is also possible to obtain the humidity RH1 by periodically obtaining several times and then averaging the humidity obtained by several times. When the acquired humidity RH1 is greater than or equal to 65%, the humidity sensor 140 acquires the indoor ambient humidity RH2 after the compressor operates for the second preset time. The second preset time may be 30 minutes, that is, the compressor is turned on and operates for 40 minutes. After the compressor has been running for 30 minutes, the humidity sensor 140 will acquire the indoor ambient humidity RH 2. It is understood that, in order to avoid the malfunction caused by a detection error, the embodiment of the present invention may continuously obtain the humidity several times, and then average the humidity to obtain the accurate indoor ambient humidity RH 2.
When the humidity RH1 is greater than or equal to 65%, the controller 150 calculates a humidity difference Δ RH between the humidity RH1 and the humidity RH2 as RH1-RH2, and determines whether the humidity difference Δ RH is less than or equal to a second preset humidity threshold, which is 5%. That is, when Δ RH is less than or equal to 5%, it indicates that the humidity change is not obvious during the operation of the air conditioner, so if the air conditioner continues to operate in the current state, the probability of the occurrence of condensed water of the air conditioner is very high, and therefore, the maximum operation frequency of the compressor of the air conditioner is set as the preset operation frequency, for example, 50 Hz. Namely, when the air conditioner determines that the frequency of the compressor is 60Hz according to the temperature difference between the indoor humidity and the set humidity, the final frequency of the compressor is 50Hz due to frequency-limited operation; assuming that the air conditioner determines that the compressor frequency is 40Hz according to the temperature difference between the indoor humidity and the set humidity, the final compressor frequency is 40Hz due to the frequency-limited operation.
Further, step S203 is followed by the steps of:
step S204, acquiring indoor environment humidity RH 3;
step S205, judging whether the humidity difference between the humidity RH3 and the humidity RH1 is greater than or equal to a third preset humidity threshold, if so, turning to step S206, otherwise, returning to step S204;
and S206, when the humidity difference between the humidity RH3 and the humidity RH1 is greater than or equal to a third preset humidity threshold value, recovering the normal operation of the compressor of the air conditioner.
After the air conditioner is frequency limited, the frequency limiting time may be controlled, for example, 30 minutes. Namely, after the air conditioner is operated for 30 minutes in a frequency limiting mode, the normal work of the compressor is recovered. In addition, after the frequency limitation is performed on the air conditioner, whether to quit the frequency limitation control can be determined according to the change of the indoor environment humidity. The method specifically comprises the following steps: the humidity sensor 140 acquires the indoor ambient humidity after limiting the frequency of the air conditioner, and is denoted as RH 3. The controller 150 is further configured to: and when the humidity difference between the humidity RH3 and the humidity RH1 is greater than or equal to a third preset humidity threshold value, the normal operation of the compressor of the air conditioner is resumed. In this embodiment, the value of the third predetermined humidity threshold is 10%. Namely, after the frequency-limited operation of the compressor is performed, when the drop amount of the indoor ambient humidity RH3 relative to the indoor ambient humidity RH1 obtained within a period of time when the compressor is started to operate is greater than or equal to 10%, the normal operation of the compressor of the air conditioner is recovered.
It can be understood that after the frequency limiting control is performed on the compressor, the humidity sensor 140 will periodically obtain the indoor ambient humidity RH3, and determine whether the frequency limiting control can be exited according to the humidity difference between the humidity RH3 and the humidity RH 1. And when the frequency limiting control can be quitted, the normal work of the compressor of the air conditioner is recovered.
Further, as shown in fig. 4, the step S130 may further include:
step S301, judging whether the humidity RH1 is smaller than a first preset humidity threshold value;
step S302, when the humidity RH1 is smaller than a first preset humidity threshold, judging whether the humidity difference between the humidity RH2 and the humidity RH1 is larger than a fourth preset humidity threshold and the humidity RH2 is larger than a fifth preset humidity threshold;
and S303, when the humidity difference between the humidity RH2 and the humidity RH1 is greater than or equal to a fourth preset humidity threshold and the humidity RH2 is greater than a fifth preset humidity threshold, setting the maximum operating frequency of the compressor of the air conditioner to be a preset operating frequency.
Specifically, the value of the first preset humidity threshold is 65%. And acquiring indoor ambient humidity RH1 in a first preset time when the compressor is started and operated. The first predetermined time may take a value of 10 minutes. During the 10 minutes, the humidity sensor 140 may acquire the humidity only once and take the humidity as the humidity RH 1; it is also possible to obtain the humidity RH1 by periodically obtaining several times and then averaging the humidity obtained by several times. When the acquired humidity RH1 is greater than or equal to 65%, the humidity sensor 140 acquires the indoor ambient humidity RH2 after the compressor operates for the second preset time. The second preset time may be 30 minutes, that is, the compressor is turned on and operates for 40 minutes. After the compressor has been running for 30 minutes, the humidity sensor 140 will acquire the indoor ambient humidity RH 2. It is understood that, in order to avoid the malfunction caused by a detection error, the embodiment of the present invention may continuously obtain the humidity several times, and then average the humidity to obtain the accurate indoor ambient humidity RH 2.
When the humidity RH1 is less than 65%, the controller 150 calculates a humidity difference Δ RH between the humidity RH1 and the humidity RH2 as RH2-RH1, and determines whether the humidity difference Δ RH is greater than a fourth preset humidity threshold and the humidity RH2 is greater than a fifth preset humidity threshold. The fourth predetermined humidity threshold value is 20%, and the fifth predetermined humidity threshold value is 80%. That is, when Δ RH is greater than or equal to 20% and RH2 is greater than or equal to 80%, it indicates that the humidity is not decreased but increased during the operation of the air conditioner, and the increased humidity is greater than 80%, so that if the operation continues in the current state, the probability of the air conditioner generating condensed water is very high, and therefore, the maximum operation frequency of the compressor of the air conditioner is set to be the preset operation frequency, for example, 50 Hz. Namely, when the air conditioner determines that the frequency of the compressor is 60Hz according to the temperature difference between the indoor humidity and the set humidity, the final frequency of the compressor is 50Hz due to frequency-limited operation; assuming that the air conditioner determines that the compressor frequency is 40Hz according to the temperature difference between the indoor humidity and the set humidity, the final compressor frequency is 40Hz due to the frequency-limited operation.
Further, the step S303 may be followed by:
step S304, acquiring indoor environment humidity RH 3;
step S305, judging whether the humidity difference between the humidity RH3 and the humidity RH1 is greater than or equal to a third preset humidity threshold, if so, turning to step S306, otherwise, returning to step S304;
and S306, when the humidity difference between the humidity RH3 and the humidity RH1 is greater than or equal to a third preset humidity threshold value, recovering the normal operation of the compressor of the air conditioner.
Specifically, the first humidity threshold value is 65%. And acquiring indoor ambient humidity RH1 in a first preset time when the compressor is started and operated. The first predetermined time may take a value of 10 minutes. During the 10 minutes, the humidity sensor 140 may acquire the humidity only once and take the humidity as the humidity RH 1; it is also possible to obtain the humidity RH1 by periodically obtaining several times and then averaging the humidity obtained by several times. When the acquired humidity RH1 is greater than or equal to 65%, the humidity sensor 140 acquires the indoor ambient humidity RH2 after the compressor operates for the second preset time. The second preset time may be 30 minutes, that is, the compressor is turned on and operates for 40 minutes. After the compressor has been running for 30 minutes, the humidity sensor 140 will acquire the indoor ambient humidity RH 2. It is understood that, in order to avoid the malfunction caused by a detection error, the embodiment of the present invention may continuously obtain the humidity several times, and then average the humidity to obtain the accurate indoor ambient humidity RH 2.
When the humidity RH1 is greater than or equal to 65%, the controller 150 calculates a humidity difference Δ RH between the humidity RH1 and the humidity RH2 as RH1-RH2, and determines whether the humidity difference Δ RH is less than or equal to a second preset humidity threshold, which is 5%. That is, when Δ RH is less than or equal to 5%, it indicates that the humidity change is not obvious during the operation of the air conditioner, so if the air conditioner continues to operate in the current state, the probability of the occurrence of condensed water of the air conditioner is very high, and therefore, the maximum operation frequency of the compressor of the air conditioner is set as the preset operation frequency, for example, 50 Hz. Namely, when the air conditioner determines that the frequency of the compressor is 60Hz according to the temperature difference between the indoor humidity and the set humidity, the final frequency of the compressor is 50Hz due to frequency-limited operation; assuming that the air conditioner determines that the compressor frequency is 40Hz according to the temperature difference between the indoor humidity and the set humidity, the final compressor frequency is 40Hz due to the frequency-limited operation.
Further, as shown in fig. 5, before the step S110, the method may further include:
and S100, when the air conditioner is started and the compressor is started, resetting both the indoor environment humidity and the air conditioner running time. In order to prevent the air conditioner from having a memory function, when the air conditioner is turned on and the compressor is started to operate, the controller 150 also clears the indoor environment humidity and the air conditioner operation time recorded in the memory so as to prevent the information recorded last time from being used for the current control.
Further, as shown in fig. 6, a frequency control process of the air conditioner compressor will be described in detail. Assume that the first preset time is 10 minutes, the second preset time is 30 minutes, the first preset humidity threshold is 65%, the second preset humidity threshold is 5%, the third preset humidity threshold is 10, the fourth preset humidity threshold is 20%, and the fifth preset humidity threshold is 80%.
