[0002] The dehumidification function is one of the important functions of the air conditioner.

[0031] It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] The dehumidification function is one of the important functions of the air conditioner. The working principle of the air conditioner dehumidification is that the indoor heat exchanger of the air conditioner is in a low temperature state. When the water vapor in the indoor return air passes through the indoor heat exchanger, the temperature is reduced to the dew point temperature under the cooling effect of the indoor heat exchanger, so that the water vapor in the air condenses into condensed water, thereby reducing the water vapor content in the indoor air and further reducing the indoor humidity. At present, most air conditioners will over-dehumidify in the dehumidification mode, making users feel relatively cold, causing users to feel uncomfortable and affecting the user experience.

[0033] Based on this, an embodiment of the present invention provides a dehumidification control method, a control device and a computer-readable storage medium for an air conditioner. In the dehumidification mode, the indoor ambient temperature is first used to distinguish whether the air conditioner is operating in a high-temperature dehumidification state or a low-temperature dehumidification state, and then the indoor ambient humidity is obtained. The target evaporating temperature and the windshield of the internal fan of the air conditioner are controlled according to the ambient humidity, thereby controlling the dehumidification capacity and the cooling output of the air conditioner. That is, under different indoor ambient temperature conditions, different target evaporating temperatures and internal fan windshields are set according to the indoor ambient humidity, so that the cooling output in the dehumidification mode is more closely aligned with the indoor ambient temperature, thereby avoiding excessive dehumidification in the dehumidification mode, thereby avoiding discomfort to the user and improving the user's usage experience.

[0034] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0035] Reference Figure 1 The first aspect of the present invention provides a dehumidification control method for an air conditioner, including but not limited to steps S110 to S120, wherein:

[0036] Step S120: when running in the dehumidification mode, obtaining the indoor environment temperature T1, and determining whether it is in the high-temperature dehumidification state or the low-temperature dehumidification state according to the comparison result between the indoor environment temperature T1 and the preset temperature threshold T0;

[0037] Step S120: in the high-temperature dehumidification state and the low-temperature dehumidification state, the indoor ambient humidity RH is obtained respectively, and the target evaporation temperature T2 and the internal fan windshield of the air conditioner are determined according to the comparison result between the indoor ambient humidity RH and the preset relative humidity threshold.

[0038] In the dehumidification control method of the air conditioner provided in the embodiment of the present invention, in the dehumidification mode, the indoor ambient temperature T1 is first used to distinguish whether the air conditioner is operating in a high-temperature dehumidification state or a low-temperature dehumidification state, and then the indoor ambient humidity RH is obtained, and the target evaporation temperature T2 and the internal fan windshield of the air conditioner are controlled according to the ambient humidity, thereby controlling the dehumidification capacity and cooling output of the air conditioner. That is, under different indoor ambient temperature conditions, different target evaporation temperatures T2 and internal fan windshields are set according to the indoor ambient humidity RH, so that the cooling output in the dehumidification mode is more closely matched to the indoor ambient temperature T1, which can avoid excessive dehumidification in the dehumidification mode, thereby avoiding discomfort to the user and improving the user's usage experience.

[0039] In the dehumidification control method provided in some embodiments of the present invention, in the high-temperature dehumidification state, when the indoor ambient humidity RH is greater than the first preset relative humidity threshold RH0, the target evaporation temperature T2 is set to the first temperature T2-target1, and the internal fan windshield is set to the first windshield.

[0040] In this embodiment, under high temperature dehumidification state, the indoor environment humidity RH is greater than the first preset relative humidity threshold RH0, that is, the air conditioner needs to operate under high temperature and high humidity state. By setting the appropriate target evaporation temperature T2 and the internal fan windshield, the cooling capacity and dehumidification capacity are both appropriate.

[0041] In the dehumidification control method provided in some embodiments of the present invention, in the high-temperature dehumidification state, when the indoor ambient humidity RH is less than the first preset relative humidity threshold RH0, the target evaporation temperature T2 is set to the second temperature T2-target2, and the internal fan windshield is set to the second windshield, the second temperature T2-target2 is greater than the first temperature T2-target1, and the second windshield is less than the first windshield.

[0042] In this embodiment, in the high temperature dehumidification state, the indoor ambient humidity RH is less than the first preset relative humidity threshold RH0, that is, the air conditioner needs to operate in the high temperature and low humidity state. By setting a second temperature T2-target2 that is higher than the target evaporation temperature (that is, the first temperature T2-target1) in the high temperature and high humidity state, and a second windshield that is smaller than the internal fan windshield (that is, the first windshield) in the high temperature and high humidity state, a lower cooling capacity and dehumidification capacity are provided in the high temperature and high humidity state, thereby saving energy and avoiding excessive dehumidification.

[0043] In the dehumidification control method provided in some embodiments of the present invention, when the air conditioner is in a cooling stable operation state before switching to the dehumidification mode, the first windshield is smaller than the windshield in the cooling stable operation state.

[0044] In this embodiment, the first windshield is the internal fan windshield under high temperature and high humidity conditions, that is, after the air conditioner switches from the stable cooling operation state to the dehumidification mode, the internal fan windshield is further lowered, which reduces the flow rate of air flowing through the indoor heat exchanger, and helps the water vapor in the air to condense into condensed water at the heat exchanger.

[0045] In the dehumidification control method provided in some embodiments of the present invention, in the low-temperature dehumidification state, when the indoor ambient humidity RH is greater than the second preset relative humidity threshold RH1, the target evaporation temperature T2 is set to the third temperature T2-target3, and the internal fan windshield is set to the third windshield.

[0046] In this embodiment, in the low-temperature dehumidification state, the indoor ambient humidity RH is greater than the second preset relative humidity threshold RH1, that is, the air conditioner needs to operate under the low-temperature and high-humidity state. By setting the appropriate target evaporation temperature T2 and the internal fan windshield, the cooling capacity and dehumidification capacity are both appropriate.

[0047] In the dehumidification control method provided in some embodiments of the present invention, in the low-temperature dehumidification state, when the indoor ambient humidity RH is less than the second preset relative humidity threshold RH1, the target evaporation temperature T2 is set to the fourth temperature T2-target4, and the internal fan windshield is set to the fourth windshield. The fourth temperature T2-target4 is greater than the third temperature T2-target3, and the fourth windshield is lower than the third windshield.

[0048] In this embodiment, in the low-temperature dehumidification state, the indoor ambient humidity RH is less than the second preset relative humidity threshold RH1, that is, the air conditioner needs to operate in the low-temperature and low-humidity state. By setting the fourth temperature T2-target4 that is higher than the target evaporation temperature (the third temperature T2-target3) in the low-temperature and high-humidity state, and the fourth windshield that is smaller than the internal fan windshield (that is, the third windshield) in the low-temperature and high-humidity state, a lower cooling capacity and dehumidification capacity are provided in the low-temperature and high-humidity state, thereby saving energy and avoiding excessive dehumidification.

[0049] In the dehumidification control method provided in some embodiments of the present invention, when the air conditioner is in a cooling stable operation state before switching to the dehumidification mode, the third windshield is smaller than the windshield in the cooling stable operation state.

[0050] In this embodiment, the third windshield is the internal fan windshield under low temperature and high humidity conditions, that is, after the air conditioner switches from the stable cooling operation state to the dehumidification mode, the internal fan windshield is further lowered, which reduces the flow rate of air flowing through the indoor heat exchanger, and helps the water vapor in the air to condense into condensed water at the heat exchanger.

[0051] In the dehumidification control method provided in some embodiments of the present invention, when the indoor ambient temperature T1 is greater than the preset temperature threshold T0, it is determined to be in high temperature dehumidification; when the indoor ambient temperature T1 is less than the preset temperature threshold T0, it is determined to be in low temperature dehumidification.

[0052] In the dehumidification control method provided in some embodiments of the present invention, the target evaporation temperature T2 in the high-temperature dehumidification state is lower than the target evaporation temperature T2 in the low-temperature dehumidification state.

[0053] In this embodiment, since the temperature is relatively high in the high-temperature dehumidification state, over-dehumidification is less likely to occur during dehumidification than in the low-temperature dehumidification state. Therefore, the target evaporation temperature T2 in the high-temperature dehumidification state can be set lower to provide sufficient cooling and dehumidification capacity.

[0054] Reference Figure 2 , Figure 2 This is a flow chart of an operation control method of an air conditioner provided by a specific embodiment of the present invention. After the air conditioner is turned on, it operates in cooling mode; if the air conditioner receives a control signal to switch to dehumidification mode, the dehumidification control method provided by the embodiment of the present invention is executed; if the air conditioner does not receive a control signal to switch to dehumidification mode, it continues to operate in conventional cooling control. It can be understood that if the air conditioner is in a stable operating state when operating in cooling mode, its internal fan windshield should also remain stable. It is assumed here that the internal fan windshield of the air conditioner remains at the fifth windshield.

[0055] When the air conditioner is running in dehumidification mode, the indoor ambient temperature T1 at the current moment is first obtained through the temperature sensor of the indoor unit, and the preset temperature threshold T0 stored in the controller of the air conditioner is obtained, and then the indoor ambient temperature T1 is compared with the preset temperature threshold T0 to determine whether the air conditioner is in a high-temperature dehumidification state or a low-temperature dehumidification state. When the indoor ambient temperature T1 is greater than the preset temperature threshold T0, the air conditioner is running in a high-temperature dehumidification state; when the indoor ambient temperature T1 is less than the preset temperature threshold T0, the air conditioner is running in a low-temperature dehumidification state. Among them, the value range of the preset temperature threshold T0 is generally set to 15℃-25℃.

[0056] Continue to refer to Figure 2In the high-temperature dehumidification state, the indoor temperature is relatively high, and it is not easy to over-dehumidify during dehumidification compared with the low-temperature dehumidification state. The target evaporation temperature T2 can be set lower, and then the indoor environment humidity RH is obtained through the humidity sensor of the indoor unit, and the first preset relative humidity threshold RH0 stored in the controller of the air conditioner is obtained for comparison, and then the target evaporation temperature T2 and the internal fan windshield of the air conditioner system are determined according to the comparison result. For example, when the indoor environment humidity RH is greater than the first preset relative humidity threshold RH0, the target evaporation temperature T2 is set to T2-target1, and the internal fan windshield is reduced by one windshield on the basis of the fifth windshield; when the indoor environment humidity RH is less than or equal to the first preset relative humidity threshold RH0, the target evaporation temperature T2 is set to T2-target2, and the internal fan windshield is reduced by two windshields on the basis of the fifth windshield, where T2-target1<T2-target2. Among them, the value range of the target evaporation temperature T2 is generally set to 3℃-15℃. It can be understood that if before entering the cooling mode, the windshield of the indoor fan is maintained at the fifth windshield, and the fifth windshield is already the lowest windshield of the indoor fan, then no matter what the comparison result between the indoor ambient humidity RH and the first preset relative humidity threshold RH0 is, the windshield of the indoor fan cannot be reduced. At this time, the windshield of the indoor fan can be kept at the fifth windshield.

[0057] Similarly, continue to refer to Figure 2 In the low-temperature dehumidification state, the indoor temperature is relatively low, and over-dehumidification is prone to occur during dehumidification. The target evaporation temperature T2 can be set higher, and then the indoor environment humidity RH is obtained through the humidity sensor of the indoor unit, and the second preset relative humidity threshold RH1 stored in the controller of the air conditioner is obtained for comparison, and then the target evaporation temperature T2 and the internal fan windshield of the air conditioner system are determined according to the comparison result. For example, when the indoor environment humidity RH is greater than the second preset relative humidity threshold RH1, the target evaporation temperature T2 is set to T2-target3, and the internal fan windshield is reduced by one windshield on the basis of the fifth windshield; when the indoor environment humidity RH is less than or equal to the second preset relative humidity threshold RH1, the target evaporation temperature T2 is set to T2-target4, and the internal fan windshield is reduced by two windshields on the basis of the fifth windshield, where T2-target3<T2-target4. It is understandable that, if the internal fan windshield is maintained at the fifth windshield before entering the cooling mode, and the fifth windshield is already the lowest windshield of the internal fan, then no matter what the comparison result between the indoor ambient humidity RH and the second preset relative humidity threshold RH1 is, the internal fan windshield cannot be reduced, and the internal fan windshield can be maintained at the fifth windshield. In addition, it should be noted that, under the same indoor ambient humidity conditions, the target evaporation temperature T2 set in the high-temperature dehumidification state should be lower than the target evaporation temperature T2 set in the low-temperature dehumidification state.

[0058] Reference Figure 3 The second aspect of the present invention provides an operation control device 300, including a memory 310, a processor 320, and a computer program stored in the memory 310 and executable on the processor 320. The processor 320 executes the program to implement the dehumidification control method of the first aspect of the present invention, for example, Figure 1 Steps S110 to S120 of the method, or executing Figure 2 Flowchart of the method in .

[0059] According to the operation control device 300 provided in the embodiment of the present invention, in the dehumidification mode, the indoor ambient temperature is first used to distinguish whether the air conditioner is operating in a high-temperature dehumidification state or a low-temperature dehumidification state, and then the indoor ambient humidity is obtained to control the target evaporating temperature and the windshield of the internal fan of the air conditioner according to the ambient humidity, thereby controlling the dehumidification capacity and cooling output of the air conditioner. That is, under different indoor ambient temperature conditions, different target evaporating temperatures and windshields of the internal fan are set according to the indoor ambient humidity, so that the cooling output in the dehumidification mode is more closely matched to the indoor ambient temperature, which can avoid excessive dehumidification in the dehumidification mode, thereby avoiding discomfort to the user and improving the user's sense of experience.

That is, under different indoor ambient temperature conditions, different target evaporating temperatures and windshields of the internal fan are set according to the indoor ambient humidity, so that the cooling output in the dehumidification mode is more closely matched to the indoor ambient temperature, and excessive dehumidification in the dehumidification mode can be avoided, thereby avoiding discomfort to the user and improving the user's sense of experience.

[0062] In addition, a fourth aspect of the present invention provides a computer-readable storage medium, the computer-readable storage medium stores computer-executable instructions, and the computer-executable instructions are used to enable a computer to execute the dehumidification control method of the first aspect of the present invention, such as executing Figure 1 Steps S110 to S120 of the method, or executing Figure 2 Flowchart of the method in .

[0063] According to the computer-readable storage medium provided in the embodiment of the present invention, in the dehumidification mode, the indoor ambient temperature is first used to distinguish whether the air conditioner is operating in a high-temperature dehumidification state or a low-temperature dehumidification state, and then the indoor ambient humidity is obtained, and the target evaporating temperature and the windshield of the internal fan of the air conditioner are controlled according to the ambient humidity, so as to control the dehumidification capacity and the cooling output of the air conditioner. That is, under different indoor ambient temperature conditions, different target evaporating temperatures and windshields of the internal fan are set according to the indoor ambient humidity, so that the cooling output in the dehumidification mode is more closely matched with the indoor ambient temperature, and excessive dehumidification in the dehumidification mode can be avoided, thereby avoiding discomfort to the user and improving the user's sense of experience.
