Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a dehumidification control method, device, and air conditioner. Background Technology

[0002] In cold and humid indoor environments, water stains on the floor are difficult to evaporate after mopping, leaving the floor damp for extended periods and increasing the risk of slipping and falling. Wooden floors are also prone to warping and mold growth in damp conditions. Therefore, floor drying functionality is a significant potential demand. While underfloor heating can be used to dry floors, this method has several drawbacks: firstly, underfloor heating is not widely available in warmer regions, limiting its applicability; secondly, the moisture evaporates into the air but cannot be expelled outdoors, creating a hot and humid environment that is detrimental to user comfort and health.

[0003] There is currently no effective solution to the problem of slow evaporation of water on the ground and the inability of the evaporated water vapor to be quickly discharged from the room in existing technologies. Summary of the Invention

[0026] If the temperature difference is greater than zero and less than the first threshold, the return air volume of the first air outlet is increased, and the heating capacity of the second heat exchange unit remains unchanged.

[0027] If the temperature difference is greater than the first threshold, the return air volume of the first air outlet is increased, and the heating capacity of the second heat exchange unit is reduced.

[0028] Furthermore, controlling the increase of the return air volume at the first air vent includes:

[0029] The adjustment amount of the return air volume is determined based on the temperature difference value; wherein, the adjustment amount of the return air volume is positively correlated with the temperature difference value;

[0050] By applying the technical solution of this invention, when there is water on the ground or the ground humidity is high, by controlling the return air from the first air vent and the exhaust air from the second air vent, and by controlling the cooling of the first heat exchange unit at the first air vent and the heating of the second heat exchange unit at the second air vent, the water stains on the ground can absorb heat and evaporate quickly. The water is then drawn into the first air vent, and through the cooling effect of the first heat exchange unit at the first air vent, the water vapor is condensed upon contact with the cold air, collected, and discharged. This enables the water stains on the floor to evaporate quickly and be discharged from the room, preventing the floor from getting damp and improving the user experience. Attached Figure Description

[0066] The optional embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0067] Example 1

[0068] This embodiment provides a dehumidification control method, which is applied to an air conditioner having a first air outlet and a second air outlet. Figure 1 This is a structural diagram of an air conditioner according to an embodiment of the present invention, such as... Figure 1 As shown, the air conditioner includes a first air vent 1 and a second air vent 2. The first air vent is located in the upper part of the room, and the second air vent is located in the lower part of the room. A first heat exchange unit 3 is installed inside the first air vent, and a second heat exchange unit 4 is installed inside the second air vent. The air conditioner also includes a fan. The dehumidification control method includes:

[0069] When preset conditions are met, the air conditioner is controlled to enter dehumidification mode. These preset conditions include: detecting water accumulation on the ground, or the ground humidity level exceeding a preset humidity level. The dehumidification mode includes: controlling the return air from the first air vent, controlling the airflow from the second air vent (in this embodiment, the airflow direction of the first and second air vents can be controlled by adjusting the fan direction); and controlling the first heat exchange unit to cool and the second heat exchange unit to heat.

[0070] It should be noted that the above-mentioned first air vent or second air vent is a type of air vent classified according to its setting location, and is not used to indicate the number of air vents. In this embodiment, there is one first air vent and one second air vent. However, in other embodiments of the present invention, there may be two or more first air vents or second air vents.

[0071] In a specific implementation, in order to determine if there is water accumulation on the indoor floor, the floor can be monitored in real time by a sensor. When the sensor detects water accumulation on the floor or the humidity value of the floor is greater than the preset humidity value, the air conditioner is controlled to automatically switch to dehumidification mode. The aforementioned sensor can be a visual sensor, a humidity sensor, etc. Alternatively, the user can manually control the air conditioner to switch to dehumidification mode after observing water accumulation on the floor.

[0072] The dehumidification control method of this embodiment, when there is water on the floor or the floor humidity is high, controls the return air from the first air vent and the exhaust air from the second air vent; and controls the first heat exchange unit at the first air vent to cool and the second heat exchange unit at the second air vent to heat. This allows water stains on the floor to absorb heat and evaporate quickly, be drawn into the first air vent, and condense upon contact with the cold air through the cooling effect of the first heat exchange unit at the first air vent. The water vapor is then collected and discharged, enabling the rapid evaporation and removal of water stains from the floor from the room, preventing the floor from getting damp, and improving the user experience.

[0073] Example 2

[0074] This embodiment provides another dehumidification control method. In order to ensure that the hot air discharged from the second air vent reaches a larger area on the ground, after controlling the air conditioner to enter dehumidification mode, it further includes: controlling the second air vent to discharge air in a swing mode. Figure 2 This is a schematic diagram of the sweeping direction of the second air outlet according to an embodiment of the present invention, as shown below. Figure 2 As shown, by sweeping the air, the hot air discharged from the second air outlet is blown to as many areas of the ground as possible, ensuring that the ground is heated evenly and facilitating the rapid evaporation of water on the ground.

[0075] Figure 3 This is a schematic diagram showing the positional relationship between the second air outlet and the ground according to an embodiment of the present invention. The arrow indicates the air outlet direction. While implementing the above-described air sweeping scheme, to ensure that the hot air discharged from the second air outlet effectively reaches the ground, as follows... Figure 3 As shown, the angle θ between the air outlet direction and the ground should always be less than 90°, that is, the air outlet direction should be towards the ground.

[0076] Figure 4 The flowchart below illustrates the dehumidification control method according to the second embodiment of the present invention. After controlling the air conditioner to enter dehumidification mode, it is also necessary to adjust the airflow according to the installation conditions of the air conditioner, such as the distance between the second air vent and the target area on the ground. Therefore, as... Figure 4 As shown, the dehumidification control method includes:

[0077] S401, when the preset conditions are met, control the air conditioner to enter dehumidification mode. The specific implementation method of step S401 is the same as in the above embodiment, and will not be repeated here.

[0078] S402, obtain the distance between the second air vent and the target area, wherein the target area is the area reached by the airflow from the second air vent.

[0079] In practice, since both the second air vent and the target area have a certain area, rather than being a single point, a fixed reference point, such as the center point (e.g., the geometric center), can be selected from both the second air vent and the target area to calculate the distance between the second air vent and the target area, as mentioned above. Figure 3 As shown, the distance between the center O of the second air vent and the center O1 of the target area on the ground is l. In specific implementation, this distance l can be obtained by using a distance sensor or by image analysis calculation method. This invention does not make any specific limitation.

[0080] S403, determine the air volume of the second air outlet based on the distance between the second air outlet and the target area; wherein, the air volume is positively correlated with the aforementioned distance.

[0081] With a fixed air volume, the greater the distance, the smaller the wind force acting on the surface. Therefore, to ensure uniform wind force across the entire ground, the area farther from the air outlet needs to have a larger air volume, and the area farther from the air outlet needs to have a smaller air volume, so as to achieve uniform wind force across the entire ground.

[0082] Example 3

[0083] Figure 5 This is a flowchart of a dehumidification control method according to a third embodiment of the present invention. To achieve the goal of not further heating the ground after all surface water has evaporated, such as... Figure 5 As shown, the dehumidification control method includes: S501, controlling the air conditioner to enter dehumidification mode when preset conditions are met. The specific implementation method of step S501 is the same as in the above embodiment, and will not be repeated here. S502, detecting the humidity of the ground; S503, if the humidity of the ground is less than or equal to the preset humidity value, controlling the second air vent to close; otherwise, controlling the second air vent to continue to open.

[0084] It should be noted that, as long as there is no conflict between the technical solutions, the solutions in the above embodiments can be combined. For example, adjusting the air volume of the second air vent based on the distance between the second air vent and the target area on the ground and detecting the humidity of the ground can be performed simultaneously.

[0085] Example 4

[0086] This embodiment provides another dehumidification control method. Figure 6 This is a flowchart of a dehumidification control method according to a fourth embodiment of the present invention. To ensure that both indoor ambient temperature and humidity remain stable at set values ​​during floor dehumidification, such as... Figure 6As shown, the dehumidification control method includes:

[0087] S601, when the preset conditions are met, control the air conditioner to enter dehumidification mode. The specific implementation method of step S601 is the same as in the above embodiment, and will not be repeated here.

[0088] S602, Obtain indoor environmental parameters, including indoor temperature and indoor humidity.

[0089] S603 controls the return air volume of the first air outlet, the heating capacity of the second heat exchange unit, and the cooling capacity of the first heat exchange unit based on indoor environmental parameters.

[0090] Since the return air volume of the first air vent and the heating capacity of the second heat exchange unit are both operating parameters affecting the indoor ambient temperature, and the cooling capacity of the first heat exchange unit is an operating parameter affecting the indoor ambient humidity, in order to control the indoor ambient temperature and indoor ambient humidity respectively, step S603 further includes: S603-1, controlling the return air volume of the first air vent and the heating capacity of the second heat exchange unit according to a first threshold; and S603-2, controlling the cooling capacity of the first heat exchange unit according to the indoor ambient humidity. The execution order of S603-1 and S603-2 is not important, and they can be executed simultaneously.

[0091] To precisely control the return air volume of the first air vent and the heating capacity of the second heat exchanger unit based on the indoor ambient temperature, S603-1 specifically includes: calculating the temperature difference between the indoor ambient temperature and the set temperature; if the temperature difference is greater than zero and less than a first threshold, it indicates that the current indoor ambient temperature is higher than the set temperature, but the difference is small. Although increasing the return air volume of the first air vent and decreasing the heating capacity of the second heat exchanger can lower the temperature, decreasing the heating capacity of the second heat exchanger will reduce the floor drying speed. Therefore, the return air volume of the first air vent can be adjusted first, i.e., the return air volume of the first air vent is increased while the heating capacity of the second heat exchanger remains unchanged; if the temperature difference is greater than the first threshold, it indicates that the current indoor ambient temperature is higher than the set temperature and the difference is large. In this case, the return air volume of the first air vent needs to be increased while the heating capacity of the second heat exchanger unit is decreased to achieve a rapid reduction in the indoor ambient temperature.

[0092] Specifically, controlling the increase of the return air volume at the first air vent includes: determining the adjustment amount of the return air volume based on the temperature difference value; wherein, the adjustment amount of the return air volume at the first air vent is positively correlated with the aforementioned temperature difference value, that is, when the current ambient temperature is higher than the set temperature, the greater the difference between the two, the greater the adjustment amount of the return air volume at the first air vent needs to be. The specific functional relationship between the adjustment amount of the return air volume at the first air vent and the aforementioned temperature difference value can be determined experimentally; after determining the adjustment amount of the return air volume, the return air volume at the first air vent is increased by a corresponding value based on the adjustment amount of the return air volume. In specific implementation, increasing the return air volume at the first air vent can be achieved by increasing the power of the fan in the air conditioner.

[0093] Controlling the reduction of the heating capacity of the second heat exchange unit includes: determining the adjustment amount of the heating capacity of the second heat exchange unit based on the deviation value between the temperature difference and the first threshold; wherein, the adjustment amount of the heating capacity is positively correlated with the deviation value, that is, when the current ambient temperature is higher than the set temperature and the difference between the two is greater than the first threshold, the greater the deviation between the difference and the first threshold, the greater the adjustment amount of the heating capacity of the second heat exchange unit needs to be. The specific functional relationship between the adjustment amount of the heating capacity of the second heat exchange unit and the above deviation can also be determined experimentally; after determining the adjustment amount of the heating capacity, the heating capacity of the second heat exchange unit is reduced by a corresponding value according to the adjustment amount of the heating capacity. If, after the heating capacity of the second heat exchange unit is reduced by a corresponding value, the temperature difference between the current ambient temperature and the set temperature is still greater than the first threshold, the return air volume of the first air outlet can be further increased. If, after adjustment, the temperature difference between the current ambient temperature and the set temperature is still greater than the first threshold, the heating capacity of the second heat exchange unit is further reduced.

[0094] In order to accurately control the cooling capacity of the first heat exchange unit according to the indoor ambient humidity, S603-2 specifically includes: controlling the cooling capacity of the first heat exchange unit according to the indoor ambient humidity, including: calculating the humidity difference between the indoor ambient humidity and the set humidity; when the humidity difference is greater than zero, controlling the cooling capacity of the first heat exchange unit to increase.

[0095] Specifically, when the humidity difference is greater than zero, the cooling capacity of the first heat exchange unit is increased, including: determining the adjustment amount of the cooling capacity of the first heat exchange unit based on the humidity difference; wherein, the adjustment amount of the cooling capacity is positively correlated with the humidity difference, that is, when the indoor ambient humidity is greater than the set humidity, the greater the difference between the two, the greater the adjustment amount of the cooling capacity of the first heat exchange unit needs to be. The specific functional relationship between the adjustment amount of the cooling capacity of the first heat exchange unit and the aforementioned humidity difference can be determined experimentally; after determining the adjustment amount of the cooling capacity, the cooling capacity of the first heat exchange unit is increased by a corresponding value based on the adjustment amount of the cooling capacity.

[0096] Since the cooling capacity of the first heat exchange unit also affects the outlet temperature of the second air vent, while increasing the cooling capacity of the first heat exchange unit, it is necessary to compensate the heating capacity of the second heat exchange unit accordingly to ensure that the airflow temperature from the second air vent to the ground remains constant. Therefore, while controlling the increase of the cooling capacity of the first heat exchange unit according to the adjustment amount of the cooling capacity, the method also includes: determining the compensation amount of the heating capacity of the second heat exchange unit based on the increase in the cooling capacity of the first heat exchange unit; and controlling the heating capacity of the second heat exchange unit to increase by a corresponding amount based on the determined compensation amount of the heating capacity. Specifically, the cooling capacity of the first heat exchange unit is increased, and after the heating capacity of the second heat exchange unit is increased, the airflow temperature from the second air vent to the ground remains constant.

[0097] As the water on the ground evaporates due to heat, it rises, increasing the humidity in the entire room. After all the water on the ground has evaporated and been drawn in by the first air vent, the indoor humidity will reach the set humidity. Through temperature adjustment, the indoor temperature will also reach the set temperature. In order to promptly exit the dehumidification mode and operate in normal cooling and heating modes after both the indoor temperature and indoor humidity have reached the set values, the method of controlling the air conditioner to enter the dehumidification mode also includes: if the indoor ambient temperature is less than or equal to the set temperature and the indoor ambient humidity is less than or equal to the set humidity, then control the air conditioner to exit the dehumidification mode.

[0098] Example 5

[0099] This embodiment provides another dehumidification control method. The present invention is based on a bidirectional dual-outlet ceiling unit structure, which has upper and lower air outlets. Both air outlets are bidirectional air outlets that can be used as both air outlets and return air outlets. The upper and lower air outlets are located in different heat exchange systems and can operate independently in cooling or heating modes. Figure 7 The flowchart of the dehumidification control method according to the fifth embodiment of the present invention is as follows: Figure 7 As shown, the dehumidification control method includes:

[0100] S1 controls the return air at the upper vent and the air outlet at the lower vent. The heat exchanger at the upper vent operates in cooling mode, and the heat exchanger at the lower vent operates in heating mode.

[0101] The cooling capacity of the heat exchanger at the upper air outlet is b1, and the heating capacity of the heat exchanger at the lower air outlet is a1.

[0102] S2 controls the downwind vent to blow air in swing mode.

[0103] Control the downwind baffle to swing along the x and y axes, blowing air across the maximum floor area it can cover in a sweeping manner.

[0104] S3 detects the distance between the downwind vent and the target area, and controls the airflow from the downwind vent based on the distance between the downwind vent and the target area.

[0105] Among them, controlling the air volume of the downwind outlet is achieved by increasing the power of the downwind outlet fan. The downwind outlet fan power P1 = f(l) is positively correlated with the distance l mentioned above. The greater the distance l, the greater the air volume; the smaller the distance l, the smaller the air volume. This keeps the wind force above the floor constant. f(l) can be obtained from experimental data.

[0106] S4 detects the indoor ambient temperature t and indoor ambient humidity h.

[0107] S5. Determine whether the difference between the indoor ambient temperature t and the set temperature tp is greater than zero. If yes, proceed to step S6; otherwise, proceed to step S11.

[0108] S6. Determine whether the difference between the indoor ambient temperature t and the set temperature tp is greater than Δt. If not, proceed to step S7; if yes, proceed to step S8.

[0109] S7, after increasing the return air volume at the upwind vent, return to step S5.

[0110] The return air volume at the top vent and the heating capacity of the heat exchanger at the bottom vent are a pair of factors affecting the indoor ambient temperature. In order to maintain the indoor ambient temperature stable at the preset target, it is necessary to collect the indoor ambient temperature t in real time as feedback to adjust the return air volume at the top vent and the heating capacity of the heat exchanger at the bottom vent. Increasing the return air volume at the top vent will accelerate the indoor air flow and lower the indoor ambient temperature. Decreasing the heating capacity of the heat exchanger at the bottom vent will lower the indoor ambient temperature. In other words, both increasing the return air volume at the top vent and decreasing the heating capacity of the heat exchanger at the bottom vent can lower the temperature. However, decreasing the heating capacity of the heat exchanger at the bottom vent will reduce the floor drying speed. Therefore, when the temperature difference is greater than zero and less than or equal to Δt, the power of the fan at the top vent should be adjusted first to keep the heating capacity of the heat exchanger at the bottom vent constant. Specifically, the return air volume at the upwind vent is increased by increasing the power of the fan at the upwind vent. Assuming the initial state, the fan power at the upwind vent is P2. When the difference between the ambient temperature t and the preset ambient temperature tp is greater than 0 and less than or equal to Δt, the fan power at the upwind vent needs to be increased accordingly. The increase is Δp = f(t - tp). The greater the temperature difference between the ambient temperature t and the preset ambient temperature tp, the greater the increase in fan power and Δp.

[0111] S8, after increasing the return air volume at the upper air vent and reducing the heat exchanger capacity at the lower air vent, return to step S5.

[0112] When the temperature difference between the ambient temperature t and the preset ambient temperature tp is greater than Δt, increasing the return air volume at the upwind vent cannot achieve rapid cooling. It is also necessary to reduce the heating capacity of the heat exchanger at the downwind vent by Δa. The value of Δa is determined based on the deviation between the temperature difference (t-tp) and the preset ambient temperature tp and Δt. Δa = f((t-tp)-Δt). Δa is positively correlated with (t-tp)-Δt, that is, the larger the value of (t-tp)-Δt, the larger Δa is.

[0113] S9. Determine whether the difference between the indoor ambient humidity h and the set humidity hp is greater than zero. If yes, proceed to step S10; otherwise, proceed to step S11.

[0114] S10, after increasing the cooling capacity of the heat exchanger at the upper air vent, return to step S9.

[0115] The cooling capacity of the upwind vent is a factor affecting air humidity. The lower the heat exchanger temperature, the more pronounced the condensation effect, and the greater the decrease in air humidity. Therefore, it is necessary to collect the indoor ambient humidity h in real time as feedback to adjust the cooling capacity of the upwind vent's heat exchanger. When the indoor ambient humidity h is greater than the set humidity hp, the cooling capacity of the upwind vent's heat exchanger is increased accordingly, with the increase in cooling capacity being Δb = f(h - hp). Simultaneously, the cooling capacity of the upwind vent's heat exchanger also affects the outlet air temperature of the downwind vent. Therefore, while increasing the cooling capacity of the upwind vent, it is necessary to compensate for the heating capacity of the downwind vent's heat exchanger, with the compensation amount being Δa1 = f(Δb). That is, the more the cooling capacity of the upwind vent's heat exchanger increases, the more the heating capacity of the downwind vent's heat exchanger is compensated, ultimately ensuring that the outlet air temperature of the downwind vent is not affected by the increase in the cooling capacity of the upwind vent's heat exchanger. Therefore, after adjustment, the cooling capacity of the upwind vent is b = b1 + Δb, and the heating capacity of the downwind vent's heat exchanger is a = a1 - Δa + Δa1. The above functional relationship can be obtained from experimental data.

[0116] S11, Determine whether the floor humidity h1 is less than the preset humidity value h 设 If not, return to step S4; if yes, proceed to step S12.

[0117] S12, close the downwind vent.

[0118] S13, determine whether the difference between the indoor ambient temperature t and the set temperature tp is less than or equal to zero, and whether the difference between the indoor ambient humidity h and the set temperature hp is less than or equal to zero. If yes, exit the dehumidification mode; otherwise, return to step S4.

[0119] It should be noted that S1 to S13 in this embodiment are only used to distinguish different steps and are not used to indicate the order in which the steps are executed.

[0120] The dehumidification control method of this embodiment can achieve a highly efficient floor drying function while maintaining a relatively comfortable indoor air environment.

[0121] Example 6

[0122] This embodiment provides a dehumidification control device. Figure 8 This is a structural diagram of a dehumidification control device according to a sixth embodiment of the present invention, as shown below. Figure 8 As shown, the dehumidification control device includes:

[0123] The mode switching module 10 is used to control the air conditioner to enter the dehumidification mode when preset conditions are met.

[0124] The control module 20 includes a first control unit 201 for controlling the first air outlet as a return air outlet and the second air outlet as an air outlet; and a second control unit 202 for controlling the first heat exchange unit to cool and the second heat exchange unit to heat.

[0125] In a specific embodiment, in order to determine that there is water accumulation on the indoor floor, the device can be connected to a sensor, which can monitor the floor in real time. When the sensor detects water accumulation on the floor, it controls the air conditioner to automatically switch to the mode where there is water accumulation on the indoor floor. The aforementioned sensor can be a visual sensor, a humidity sensor, etc. The user can also manually control the air conditioner to switch to dehumidification mode after observing water accumulation on the floor.

[0126] In this embodiment, the dehumidification control device controls the air conditioner to enter dehumidification mode when there is water on the floor. The control module controls the return air from the first air vent and the exhaust air from the second air vent. It also controls the first heat exchange unit at the first air vent to cool and the second heat exchange unit at the second air vent to heat. This allows the water stains on the floor to absorb heat and evaporate quickly. The water is then drawn into the first air vent, and the water vapor is condensed upon contact with the cold air by the first heat exchange unit at the first air vent. The water vapor is then collected and discharged. This enables the water stains on the floor to evaporate quickly and be discharged from the room, preventing the floor from getting damp and improving the user experience.

[0127] Example 7

[0128] This embodiment provides a dehumidification control device. Figure 9 This is a structural diagram of the control module according to the seventh embodiment of the present invention, as shown below. Figure 9 As shown, the dehumidification control device includes:

[0129] The third control unit 203 is used to control the second air outlet to output air in the swing mode, and to control the angle between the air outlet direction and the ground to always be less than 90°.

[0130] After controlling the air conditioner to enter dehumidification mode, it is also necessary to adjust the airflow according to the installation of the air conditioner, such as the distance of the second air vent from the ground. Therefore, if Figure 9 As shown, the control module 20 further includes: a first detection unit 204, used to obtain the distance between the second air vent and the target area on the ground; and a fourth control unit 205, used to control the air volume of the second air vent according to the distance between the second air vent and the target area on the ground; wherein the air volume is positively correlated with the distance.

[0131] To prevent the ground from heating up again after all the surface water has evaporated, such as... Figure 9 As shown, the control module 20 also includes: a second detection unit 206 for detecting the humidity of the ground; and a fifth control unit 207 for controlling the second air vent to close when the humidity of the ground is less than or equal to a preset humidity value, and controlling the second air vent to continue to open when the humidity of the ground is greater than the preset humidity value.

[0132] To ensure that both indoor temperature and humidity remain stable at set values ​​during floor dehumidification, such as... Figure 9 As shown, the control module 20 further includes: a parameter acquisition unit 208, used to acquire indoor environmental parameters, including indoor ambient temperature and indoor ambient humidity; and a sixth control unit 209, used to control the return air volume of the first air vent, the heating capacity of the second heat exchange unit, and the cooling capacity of the first heat exchange unit according to the indoor environmental parameters. The sixth control unit 209 includes: a first control subunit 209-1, used to control the return air volume of the first air vent and the heating capacity of the second heat exchange unit according to the indoor ambient temperature; and a second control subunit 209-2, used to control the cooling capacity of the first heat exchange unit according to the indoor ambient humidity.

[0133] The first control subunit 209-1 is specifically used for: calculating the temperature difference between the indoor ambient temperature and the set temperature; when the temperature difference is greater than zero and less than a first threshold, controlling the return air volume of the first air vent to increase, and controlling the heating capacity of the second heat exchange unit to remain unchanged; when the temperature difference is greater than the first threshold, controlling the return air volume of the first air vent to increase, and controlling the heating capacity of the second heat exchange unit to decrease. More specifically, the first control subunit 209-1 is used to determine the adjustment amount of the return air volume based on the temperature difference; wherein the adjustment amount of the return air volume is positively correlated with the temperature difference; controlling the return air volume of the first air vent to increase by a corresponding value based on the adjustment amount of the return air volume. And, it is used to determine the adjustment amount of the heating capacity of the second heat exchange unit based on the deviation value between the temperature difference and the first threshold; wherein the adjustment amount of the heating capacity is positively correlated with the deviation value; controlling the heating capacity of the second heat exchange unit to decrease by a corresponding value based on the adjustment amount of the heating capacity.

[0134] The second control subunit 209-2 is specifically used to: calculate the humidity difference between the indoor ambient humidity and the set humidity; and when the humidity difference is greater than zero, control the cooling capacity of the first heat exchange unit to increase. More specifically, the second control subunit 209-2 is used to determine the adjustment amount of the cooling capacity of the first heat exchange unit based on the humidity difference; wherein the adjustment amount of the cooling capacity is positively correlated with the humidity difference; and control the cooling capacity of the first heat exchange unit to increase by a corresponding value based on the adjustment amount of the cooling capacity.

[0135] Since the cooling capacity of the first heat exchange unit also affects the outlet temperature of the second air vent, while increasing the cooling capacity of the first heat exchange unit, it is necessary to compensate the heating capacity of the second heat exchange unit accordingly to ensure that the airflow temperature from the second air vent to the ground remains unchanged. Therefore, the first control subunit 209-1 is also used to: determine the compensation amount of the heating capacity of the second heat exchange unit based on the increase in the cooling capacity of the first heat exchange unit; and control the heating capacity of the second heat exchange unit to increase by a corresponding value based on the determined compensation amount of the heating capacity. Wherein, the cooling capacity of the first heat exchange unit is increased, and after the heating capacity of the second heat exchange unit is increased, the airflow temperature from the second air vent to the ground remains unchanged.

[0136] As the water on the ground evaporates due to heat, it rises, increasing the humidity in the entire room. After all the water on the ground has evaporated and is drawn in by the first air vent, the indoor humidity will reach the set humidity. Through temperature adjustment, the indoor temperature will also reach the set temperature. In order to exit the dehumidification mode in time and run the normal cooling and heating modes after both the indoor temperature and indoor humidity have reached the set values, the control module 20 also includes: a seventh control unit 210, which is used to control the air conditioner to exit the dehumidification mode when the indoor ambient temperature is less than or equal to the set temperature and the indoor ambient humidity is less than or equal to the set humidity.
