Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioning, and specifically relates to a control method and device for air conditioning dehumidification, an air conditioner, a storage medium and a computer program product. Background Art

[0002] During the rainy season, the outdoor ambient temperature is generally not high, and users do not have much demand for cooling, but the demand for dehumidification is relatively high. Therefore, air conditioners usually have a dehumidification function to meet users' dehumidification needs.

[0003] When the air conditioner is dehumidifying, the outdoor environment is generally not bad, so the set temperature is usually not too low. The air conditioner is easy to reach the temperature point and shut down. After the shutdown, the operating frequency of the compressor is reduced, so the temperature of the evaporator increases, the dehumidification efficiency is weakened, and the indoor humidity is easy to rise, resulting in large humidity fluctuations and unsatisfactory dehumidification effects. In addition, reducing the operating frequency of the compressor will easily cause the compressor to operate unstably, affecting the normal operation of the air conditioner.

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] According to an embodiment of the present invention, a method for controlling air conditioning dehumidification is provided, wherein the air conditioner comprises: an electric auxiliary heating component, an indoor fan, and a compressor; the electric auxiliary heating component is used to adjust the air outlet temperature of the indoor unit.

[0031] The electric auxiliary heating component can be installed at the air outlet of the indoor unit. The cold air cooled by the evaporator passes through the electric auxiliary heating component and then discharged from the air outlet. The electric auxiliary heating component is an electric heater that can release heat. After the electric auxiliary heating component is turned on, the cold air is heated at the electric auxiliary heating component and then discharged, thereby increasing the air outlet temperature of the air conditioner.

[0032] like Figure 1 The flowchart of an embodiment of the method of the present invention is shown in FIG. The air conditioning dehumidification control method may include: steps S110 to S140.

[0033] At step S110, after the air conditioner turns on the dehumidification mode, the wind speed of the internal fan is controlled to be the set wind speed and the operating frequency of the compressor is controlled to be the set operating frequency; the set wind speed is smaller than the default wind speed of the internal fan in the dehumidification mode, and the set operating frequency is greater than the default operating frequency of the compressor in the dehumidification mode.

[0034] In dehumidification mode, the default wind speed of the internal fan is usually low. This solution further reduces the wind speed for dehumidification based on the low wind speed, such as setting the wind speed to silent or ultra-silent. Usually the default operating frequency of the compressor is between 40Hz and 50Hz. This solution further increases the operating frequency, such as controlling the compressor to operate at 60Hz for dehumidification. Therefore, by lowering the wind speed of the internal fan and increasing the compressor frequency for dehumidification, the evaporation temperature can be reduced and the dehumidification capacity of the air conditioner can be improved. Optionally, the compressor can also operate at the default operating frequency.

[0035] In step S120, the indoor ambient temperature is obtained.

[0036] In step S130, the temperature interval of the indoor ambient temperature is determined.

[0037] In some embodiments, in step S130, the specific process of determining the temperature range in which the indoor ambient temperature is located includes: recording the difference between the indoor ambient temperature and the set indoor temperature as the temperature difference, and judging the size of the temperature difference. If the temperature difference is less than the preset first temperature value, it is determined that the indoor ambient temperature is in the preset first temperature range; if the temperature difference is less than the preset second temperature value, it is determined that the indoor ambient temperature is in the preset second temperature range; if the temperature difference is less than the preset third temperature value, it is determined that the indoor ambient temperature is in the preset third temperature range; wherein, the preset first temperature value>the preset second temperature value>the preset third temperature value.

[0038] The preset first temperature value can be set to 0.5°C, the preset second temperature value can be set to -0.5°C, and the preset third temperature value can be set to -0.8°C. As the air conditioner is running, the indoor temperature continues to decrease. When the indoor temperature minus the set indoor temperature is less than 0.5°C, the indoor ambient temperature is in the preset first temperature range. At this time, the indoor temperature is basically the same as the set indoor temperature. In order to prevent the indoor temperature from further decreasing and affecting the indoor environmental comfort, the windshield of the indoor fan is dynamically adjusted to reduce the cooling output of the air conditioner. If the indoor temperature still drops after adjusting the windshield of the indoor fan, and the indoor temperature minus the set indoor temperature is less than -0.5°C, that is, the indoor ambient temperature is in the preset second temperature range, the electric auxiliary heating component is used to increase the air outlet temperature of the air conditioner to increase the indoor temperature to the set indoor temperature. If the electric auxiliary heating component still cannot increase the indoor temperature to the set indoor temperature after turning on the electric auxiliary heating component, and the indoor temperature minus the set indoor temperature is less than -0.8°C, that is, the indoor ambient temperature is in the preset third temperature range, the operating frequency of the compressor is reduced at this time, and the pipe temperature of the evaporator is increased to increase the air outlet temperature of the air conditioner.

[0039] Thus, while dehumidifying at a higher operating frequency, the indoor temperature is made equal to the set indoor temperature by using a step-by-step heating method according to the temperature range of the indoor ambient temperature, thereby improving the indoor comfort during the dehumidification process.

[0040] In step S140, the wind speed of the indoor fan, the operating frequency of the compressor, the start of the electric auxiliary heating component and the operating power of the electric auxiliary heating component after the start of the electric auxiliary heating component are controlled respectively according to the interval of the indoor ambient temperature.

[0041] In this solution, when the indoor ambient temperature reaches the set indoor temperature, the air conditioner does not stop, and the compressor continues to run at the set operating frequency to ensure the dehumidification efficiency of the air conditioner and avoid the indoor humidity rising after the compressor frequency is reduced. At the same time, the air outlet temperature of the air conditioner is adjusted in steps according to the temperature range of the indoor ambient temperature, so that the indoor temperature is equal to the set indoor temperature, ensuring the indoor comfort during the dehumidification process.

[0042] In some embodiments, in step S140, the specific process of controlling the wind speed of the indoor fan, the operating frequency of the compressor, the activation of the electric auxiliary heating component, and the operating power of the electric auxiliary heating component after being activated according to the interval in which the indoor ambient temperature is located includes: when the indoor ambient temperature is in a preset first temperature interval, lowering the wind speed of the indoor fan by one level; then determining whether the temperature difference is less than a preset second temperature value; if the temperature difference is less than the preset second temperature value, continuing to lower the wind speed of the indoor fan by one level, until the temperature difference is greater than or equal to the preset second temperature value, and then keeping the wind speed of the indoor fan unchanged.

[0043] During the dehumidification process, the indoor temperature gradually decreases. When the indoor temperature drops to the first temperature range, the wind speed of the indoor fan is lowered by one level to reduce the output of cooling capacity and slow down the rate of decrease of the indoor temperature, so that the indoor temperature is the same as the set indoor temperature. If the difference between the indoor temperature and the set indoor temperature is within 0.5℃, the indoor temperature is considered to be the same as the set indoor temperature.

[0044] If the indoor temperature drops to the second temperature range, it means that the air conditioner outputs too much cooling capacity at the current wind speed of the indoor fan, and the wind speed of the indoor fan needs to be lowered to reduce the cooling capacity output. After the wind speed is lowered, it is determined again whether the temperature difference is less than the preset second temperature value within a period of time. If the temperature difference is still less than the preset second temperature value, the wind speed of the indoor fan is further lowered until the temperature difference is less than the preset first temperature value and greater than or equal to the preset second temperature value, that is, -0.5℃≤Indoor temperature-set indoor temperature<0.5℃, and then the wind speed of the indoor fan is maintained unchanged.

[0045] In some embodiments, the air conditioner also includes an evaporator; the method also includes: obtaining the tube temperature of the evaporator; judging the relationship between the tube temperature of the evaporator and a preset tube temperature; if the tube temperature of the evaporator is greater than or equal to the preset tube temperature, keeping the wind speed of the internal fan unchanged; if the tube temperature of the evaporator is less than the preset tube temperature, raising the wind speed of the internal fan by one level.

[0046] When the indoor temperature drops to the first temperature range, the wind speed of the internal fan will be lowered to reduce the cold output to the room, preventing the indoor temperature from dropping below the set indoor temperature. At the same time, in order to ensure the dehumidification effect without reducing the operating frequency of the compressor, the cold is continuously accumulated at the evaporator, and the tube temperature of the evaporator continues to drop. During the dehumidification process, water hangs on the evaporator. If the temperature of the evaporator continues to drop, it is easy to cause frost and ice on the evaporator. Therefore, it is necessary to ensure that the evaporator will not frost while lowering the wind speed of the internal fan. Specifically, the preset tube temperature can be set to 4°C. When the tube temperature of the evaporator is ≥4°C, it is considered that the evaporator will not frost, and the wind speed of the internal fan remains unchanged; when the tube temperature of the evaporator is <4°C, the evaporator may frost, and the tube temperature of the evaporator needs to be increased. At this time, the wind speed of the internal fan is increased to increase the air flow rate through the evaporator, so that the cold of the evaporator is taken away by the airflow and the tube temperature of the evaporator is increased. By preventing the evaporator tube temperature from being too low and frosting during the dehumidification process, the stability of the air conditioner operation is ensured.

[0047] In some embodiments, in step S140, the specific process of controlling the wind speed of the indoor fan, the operating frequency of the compressor, the activation of the electric auxiliary heating component, and the operating power of the electric auxiliary heating component after being activated according to the interval in which the indoor ambient temperature is located, further includes: when the indoor ambient temperature is in a preset second temperature interval, turning on the electric auxiliary heating component; then determining whether the temperature difference is less than the preset second temperature value; if the temperature difference is less than the preset second temperature value, increasing the operating power of the electric auxiliary heating component until the temperature difference is greater than or equal to the preset second temperature value, and then keeping the operating power of the electric auxiliary heating component unchanged.

[0048] If the indoor temperature continues to drop to the second temperature range, it means that lowering the wind speed of the indoor fan cannot balance the cooling output of the air conditioner. At this time, the electric auxiliary heating component is turned on, and the heat generated by the electric auxiliary heating component is used to heat the air after the evaporator is cooled, thereby increasing the air outlet temperature of the air conditioner and raising the indoor temperature to the set temperature.

[0049] The heating power of the electric auxiliary heating component can be adjusted to more accurately control the air outlet temperature of the air conditioner. For example, the electric auxiliary heating component can be adjusted steplessly between 300W and 1000W. After the electric auxiliary heating component is turned on for a period of time, if the temperature difference is still less than the second temperature value, the power of the electric auxiliary heating is increased until the temperature difference is less than the preset first temperature value and greater than or equal to the preset second temperature value, and then the current power is maintained unchanged or the electric auxiliary heating component is turned off, or the electric auxiliary heating component is turned off when the temperature difference is greater than the preset first temperature value. In this way, by using the electric auxiliary heating component to balance the cooling output of the air conditioner during the continuous decrease in indoor temperature, the indoor temperature is made the same as the set indoor temperature, ensuring indoor comfort during the dehumidification process.

[0050] In some embodiments, in step S140, the specific process of controlling the wind speed of the indoor fan, the operating frequency of the compressor, the activation of the electric auxiliary heating component, and the operating power of the electric auxiliary heating component after being activated according to the interval in which the indoor ambient temperature is located also includes: when the indoor ambient temperature is in a preset third temperature interval, reducing the operating frequency of the compressor, and then determining whether the temperature difference is less than a preset second temperature value; if the temperature difference is less than the preset second temperature value, continuing to reduce the operating frequency of the compressor until the temperature difference is greater than or equal to the preset second temperature value, and keeping the operating frequency of the compressor unchanged.

[0051] If the power of the electric auxiliary heating component is turned to the maximum, but the indoor temperature continues to drop to the third temperature range, the compressor operating frequency is reduced to reduce the cooling capacity at the evaporator. Specifically, when the indoor temperature enters the third temperature range, the compressor operating frequency is reduced once, for example, by 5Hz. After a period of time, if the temperature difference is still less than the preset second temperature value, the compressor operating frequency is further reduced. If the compressor operating frequency is reduced to the minimum value and it is still determined that the compressor frequency needs to be reduced, the compressor is directly controlled to stop. In this way, the cooling capacity output by the air conditioner is balanced by reducing the compressor frequency or even stopping the compressor.

[0052] Figure 3 FIG. 1 is a flow chart of another embodiment of the air conditioning dehumidification control method of the present invention. Figure 3 As shown, the method includes:

[0053] Step 1: After the air conditioner turns on the dehumidification mode, the indoor fan runs at a lower wind speed, and the compressor runs at a default frequency or higher than a higher frequency. The indoor temperature T1 is continuously detected.

[0054] Step 2, determine whether the indoor temperature T1-set temperature T2 < 0.5℃. If T1-T2 ≥ 0.5℃, the wind speed of the indoor fan remains unchanged; if T1-T2 < 0.5℃, the wind speed of the indoor fan is dynamically adjusted, and step 3 is executed. Under dynamic adjustment, the highest wind speed of the indoor fan is the current wind speed, and the adjustment method is to lower the wind speed. The target of dynamic adjustment is -0.5℃ ≤ T1-T2 < 0.5℃, and the tube temperature of the evaporator is ≥ 4℃.

[0055] Step 3, determine whether T1-T2<-0.5℃. If T1-T2≥-0.5℃, execute step 2; if T1-T2<-0.5℃, control the wind speed of the internal fan unchanged, start the electric auxiliary heating component, and dynamically adjust the power of the electric auxiliary heating component. When the power of the electric auxiliary heating component reaches the maximum power, execute step 4. The goal of dynamic adjustment is -0.5℃≤T1-T2<0.5℃.

[0056] Step 4, determine whether T1-T2<-0.8℃. If T1-T2≥-0.8℃, execute step 3; if T1-T2<-0.8℃, reduce the frequency of the compressor. If the compressor frequency is already the lowest value, control the compressor to stop.

[0057] The technical solution of this embodiment is adopted, and an electric auxiliary heating component is provided, and the electric auxiliary heating component is used to adjust the air outlet temperature of the indoor unit; after the air conditioner turns on the dehumidification mode, the wind speed of the indoor fan is controlled to be the set wind speed, and the operating frequency of the compressor is controlled to be the set operating frequency; the temperature range of the indoor ambient temperature is determined, and the wind speed of the indoor fan, the operating frequency of the compressor, the opening of the electric auxiliary heating component, and the operating power after the electric auxiliary heating component is turned on are controlled according to the temperature range of the indoor ambient temperature. Thus, by keeping the compressor running during the dehumidification process, controlling the wind speed of the indoor fan, the operating power of the electric auxiliary heating component, and the operating frequency of the compressor to adjust the cooling output of the air conditioner during the dehumidification process, the air conditioner always has a high dehumidification efficiency, avoiding the indoor humidity from rising, and ensuring good indoor comfort.

[0058] According to an embodiment of the present invention, a control device for air conditioning dehumidification corresponding to the control method for air conditioning dehumidification is also provided. The air conditioner comprises: an electric auxiliary heating component, an indoor fan, and a compressor; the electric auxiliary heating component is used to adjust the outlet air temperature of the indoor unit.

[0059] The electric auxiliary heating component can be installed at the air outlet of the indoor unit. The cold air cooled by the evaporator passes through the electric auxiliary heating component and then discharged from the air outlet. The electric auxiliary heating component is an electric heater that can release heat. After the electric auxiliary heating component is turned on, the cold air is heated at the electric auxiliary heating component and then discharged, thereby increasing the air outlet temperature of the air conditioner.

[0060] See also Figure 2 The structure diagram of an embodiment of the device of the present invention is shown in FIG. The air conditioning and dehumidification control device may include: an acquisition unit 102 and a control unit 104 .

[0061] The control unit 104 is configured to control the wind speed of the internal fan to be a set wind speed and the operating frequency of the compressor to be a set operating frequency after the air conditioner turns on the dehumidification mode; the set wind speed is less than the default wind speed of the internal fan in the dehumidification mode, and the set operating frequency is greater than the default operating frequency of the compressor in the dehumidification mode. The specific functions and processing of the control unit 104 refer to step S110.

[0062] In dehumidification mode, the default wind speed of the internal fan is usually low. This solution further reduces the wind speed for dehumidification based on the low wind speed, such as setting the wind speed to silent or ultra-silent. Usually the default operating frequency of the compressor is between 40Hz and 50Hz. This solution further increases the operating frequency, such as controlling the compressor to operate at 60Hz for dehumidification. Therefore, by lowering the wind speed of the internal fan and increasing the compressor frequency for dehumidification, the evaporation temperature can be reduced and the dehumidification capacity of the air conditioner can be improved. Optionally, the compressor can also operate at the default operating frequency.

[0063] The acquisition unit 102 is configured to acquire the indoor environment temperature. The specific functions and processing of the acquisition unit 102 refer to step S120.

[0064] The control unit 104 is further configured to determine the temperature interval that the indoor ambient temperature is in. The specific functions and processing of the control unit 104 refer to step S130.

[0065] In some embodiments, the control unit 104 determines the specific process of the temperature range in which the indoor ambient temperature is located, including: recording the difference between the indoor ambient temperature and the set indoor temperature as the temperature difference, and judging the size of the temperature difference. If the temperature difference is less than the preset first temperature value, it is determined that the indoor ambient temperature is in the preset first temperature range; if the temperature difference is less than the preset second temperature value, it is determined that the indoor ambient temperature is in the preset second temperature range; if the temperature difference is less than the preset third temperature value, it is determined that the indoor ambient temperature is in the preset third temperature range; wherein, the preset first temperature value>the preset second temperature value>the preset third temperature value.

[0066] The preset first temperature value can be set to 0.5°C, the preset second temperature value can be set to -0.5°C, and the preset third temperature value can be set to -0.8°C. As the air conditioner is running, the indoor temperature continues to decrease. When the indoor temperature minus the set indoor temperature is less than 0.5°C, the indoor ambient temperature is in the preset first temperature range. At this time, the indoor temperature is basically the same as the set indoor temperature. In order to prevent the indoor temperature from further decreasing and affecting the indoor environmental comfort, the windshield of the indoor fan is dynamically adjusted to reduce the cooling output of the air conditioner. If the indoor temperature still drops after adjusting the windshield of the indoor fan, and the indoor temperature minus the set indoor temperature is less than -0.5°C, that is, the indoor ambient temperature is in the preset second temperature range, the electric auxiliary heating component is used to increase the air outlet temperature of the air conditioner to increase the indoor temperature to the set indoor temperature. If the electric auxiliary heating component still cannot increase the indoor temperature to the set indoor temperature after turning on the electric auxiliary heating component, and the indoor temperature minus the set indoor temperature is less than -0.8°C, that is, the indoor ambient temperature is in the preset third temperature range, the operating frequency of the compressor is reduced at this time, and the pipe temperature of the evaporator is increased to increase the air outlet temperature of the air conditioner.

[0067] Thus, while dehumidifying at a higher operating frequency, the indoor temperature is made equal to the set indoor temperature by using a step-by-step heating method according to the temperature range of the indoor ambient temperature, thereby improving the indoor comfort during the dehumidification process.

[0068] The control unit 104 is further configured to control the wind speed of the indoor fan, the operating frequency of the compressor, the start of the electric auxiliary heating component, and the operating power of the electric auxiliary heating component after the start of the electric auxiliary heating component according to the range of the indoor ambient temperature. The specific functions and processing of the control unit 104 refer to step S140.

[0069] In this solution, when the indoor ambient temperature reaches the set indoor temperature, the air conditioner does not stop, and the compressor continues to run at the set operating frequency to ensure the dehumidification efficiency of the air conditioner and avoid the indoor humidity rising after the compressor frequency is reduced. At the same time, the air outlet temperature of the air conditioner is adjusted in steps according to the temperature range of the indoor ambient temperature, so that the indoor temperature is equal to the set indoor temperature, ensuring the indoor comfort during the dehumidification process.

[0070] In some embodiments, the control unit 104 controls the wind speed of the indoor fan, the operating frequency of the compressor, the activation of the electric auxiliary heating component, and the operating power of the electric auxiliary heating component after being activated according to the interval in which the indoor ambient temperature is located, including: when the indoor ambient temperature is in a preset first temperature interval, lowering the wind speed of the indoor fan by one level; then determining whether the temperature difference is less than a preset second temperature value; if the temperature difference is less than the preset second temperature value, continuing to lower the wind speed of the indoor fan by one level, until the temperature difference is greater than or equal to the preset second temperature value, and then keeping the wind speed of the indoor fan unchanged.

[0071] During the dehumidification process, the indoor temperature gradually decreases. When the indoor temperature drops to the first temperature range, the wind speed of the indoor fan is lowered by one level to reduce the output of cooling capacity and slow down the rate of decrease of the indoor temperature, so that the indoor temperature is the same as the set indoor temperature. If the difference between the indoor temperature and the set indoor temperature is within 0.5℃, the indoor temperature is considered to be the same as the set indoor temperature.

[0072] If the indoor temperature drops to the second temperature range, it means that the air conditioner outputs too much cooling capacity at the current wind speed of the indoor fan, and the wind speed of the indoor fan needs to be lowered to reduce the cooling capacity output. After the wind speed is lowered, it is determined again whether the temperature difference is less than the preset second temperature value within a period of time. If the temperature difference is still less than the preset second temperature value, the wind speed of the indoor fan is further lowered until the temperature difference is less than the preset first temperature value and greater than or equal to the preset second temperature value, that is, -0.5℃≤Indoor temperature-set indoor temperature<0.5℃, and then the wind speed of the indoor fan is maintained unchanged.

[0073] In some embodiments, the air conditioner further includes an evaporator. The control unit 104 is further configured to: obtain the tube temperature of the evaporator; determine the relationship between the tube temperature of the evaporator and a preset tube temperature; if the tube temperature of the evaporator is greater than or equal to the preset tube temperature, keep the wind speed of the internal fan unchanged; if the tube temperature of the evaporator is less than the preset tube temperature, increase the wind speed of the internal fan by one level.

[0074] When the indoor temperature drops to the first temperature range, the wind speed of the internal fan will be lowered to reduce the cold output to the room, preventing the indoor temperature from dropping below the set indoor temperature. At the same time, in order to ensure the dehumidification effect without reducing the operating frequency of the compressor, the cold is continuously accumulated at the evaporator, and the tube temperature of the evaporator continues to drop. During the dehumidification process, water hangs on the evaporator. If the temperature of the evaporator continues to drop, it is easy to cause frost and ice on the evaporator. Therefore, it is necessary to ensure that the evaporator will not frost while lowering the wind speed of the internal fan. Specifically, the preset tube temperature can be set to 4°C. When the tube temperature of the evaporator is ≥4°C, it is considered that the evaporator will not frost, and the wind speed of the internal fan remains unchanged; when the tube temperature of the evaporator is <4°C, the evaporator may frost, and the tube temperature of the evaporator needs to be increased. At this time, the wind speed of the internal fan is increased to increase the air flow rate through the evaporator, so that the cold of the evaporator is taken away by the airflow and the tube temperature of the evaporator is increased. By preventing the evaporator tube temperature from being too low and frosting during the dehumidification process, the stability of the air conditioner operation is ensured.

[0075] In some embodiments, the control unit 104 controls the wind speed of the indoor fan, the operating frequency of the compressor, the activation of the electric auxiliary heating component, and the operating power of the electric auxiliary heating component after being activated according to the interval in which the indoor ambient temperature is located, and further includes: when the indoor ambient temperature is in a preset second temperature interval, turning on the electric auxiliary heating component; then determining whether the temperature difference is less than the preset second temperature value; if the temperature difference is less than the preset second temperature value, increasing the operating power of the electric auxiliary heating component until the temperature difference is greater than or equal to the preset second temperature value, and then keeping the operating power of the electric auxiliary heating component unchanged.

[0076] If the indoor temperature continues to drop to the second temperature range, it means that lowering the wind speed of the indoor fan cannot balance the cooling output of the air conditioner. At this time, the electric auxiliary heating component is turned on, and the heat generated by the electric auxiliary heating component is used to heat the air after the evaporator is cooled, thereby increasing the air outlet temperature of the air conditioner and raising the indoor temperature to the set temperature.

[0077] The heating power of the electric auxiliary heating component can be adjusted to more accurately control the air outlet temperature of the air conditioner. For example, the electric auxiliary heating component can be adjusted steplessly between 300W and 1000W. After the electric auxiliary heating component is turned on for a period of time, if the temperature difference is still less than the second temperature value, the power of the electric auxiliary heating is increased until the temperature difference is less than the preset first temperature value and greater than or equal to the preset second temperature value, and then the current power is maintained unchanged or the electric auxiliary heating component is turned off, or the electric auxiliary heating component is turned off when the temperature difference is greater than the preset first temperature value. In this way, by using the electric auxiliary heating component to balance the cooling output of the air conditioner during the continuous decrease in indoor temperature, the indoor temperature is made the same as the set indoor temperature, ensuring indoor comfort during the dehumidification process.

[0078] In some embodiments, the control unit 104 controls the wind speed of the indoor fan, the operating frequency of the compressor, the activation of the electric auxiliary heating component, and the operating power of the electric auxiliary heating component after being activated according to the interval in which the indoor ambient temperature is located, and further includes: when the indoor ambient temperature is in a preset third temperature interval, reducing the operating frequency of the compressor, and then determining whether the temperature difference is less than a preset second temperature value; if the temperature difference is less than the preset second temperature value, continuing to reduce the operating frequency of the compressor until the temperature difference is greater than or equal to the preset second temperature value, and keeping the operating frequency of the compressor unchanged.

[0079] If the power of the electric auxiliary heating component is turned to the maximum, but the indoor temperature continues to drop to the third temperature range, the compressor operating frequency is reduced to reduce the cooling capacity at the evaporator. Specifically, when the indoor temperature enters the third temperature range, the compressor operating frequency is reduced once, for example, by 5Hz. After a period of time, if the temperature difference is still less than the preset second temperature value, the compressor operating frequency is further reduced. If the compressor operating frequency is reduced to the minimum value and it is still determined that the compressor frequency needs to be reduced, the compressor is directly controlled to stop. In this way, the cooling capacity output by the air conditioner is balanced by reducing the compressor frequency or even stopping the compressor.

[0080] Figure 3 FIG. 1 is a flow chart of another embodiment of the air conditioning dehumidification control method of the present invention. Figure 3 As shown, the method includes:

[0081] Step 1: After the air conditioner turns on the dehumidification mode, the indoor fan runs at a lower wind speed, and the compressor runs at a default frequency or higher than a higher frequency. The indoor temperature T1 is continuously detected.

[0082] Step 2, determine whether the indoor temperature T1-set temperature T2 < 0.5℃. If T1-T2 ≥ 0.5℃, the wind speed of the indoor fan remains unchanged; if T1-T2 < 0.5℃, the wind speed of the indoor fan is dynamically adjusted, and step 3 is executed. Under dynamic adjustment, the highest wind speed of the indoor fan is the current wind speed, and the adjustment method is to lower the wind speed. The target of dynamic adjustment is -0.5℃ ≤ T1-T2 < 0.5℃, and the tube temperature of the evaporator is ≥ 4℃.

[0083] Step 3, determine whether T1-T2<-0.5℃. If T1-T2≥-0.5℃, execute step 2; if T1-T2<-0.5℃, control the wind speed of the internal fan unchanged, start the electric auxiliary heating component, and dynamically adjust the power of the electric auxiliary heating component. When the power of the electric auxiliary heating component reaches the maximum power, execute step 4. The goal of dynamic adjustment is -0.5℃≤T1-T2<0.5℃.

[0084] Step 4, determine whether T1-T2<-0.8℃. If T1-T2≥-0.8℃, execute step 3; if T1-T2<-0.8℃, reduce the frequency of the compressor. If the compressor frequency is already the lowest value, control the compressor to stop.
