[0002] With the popularization of intelligent technology, intelligent air conditioners have become an indispensable device in home life. Moreover, air conditioners can not only adjust the indoor temperature, but also adjust the indoor humidity, that is, air conditioners have a dehumidification mode. When the indoor humidity is very high, the main purpose is to reduce the indoor humidity, and the cooling is secondary. The operation of the indoor fan and the air conditioner compressor is controlled.

[0003] Currently, in some regions, such as southern coastal cities, the humidity is relatively high. When the ambient temperature is below 16°C, there is still a dehumidification demand. However, the dehumidification function of existing air conditioners cannot operate when the ambient temperature is below 16°C. Moreover, the existing constant temperature dehumidification mode will add a reversing valve to the indoor unit of the air conditioner, increasing the cost of the air conditioner. Therefore, it is necessary to further improve the performance of the air conditioner to meet the low-temperature dehumidification requirements in some regions. Summary of the Invention

It should be understood that such data can be interchanged under appropriate circumstances so as to implement the embodiments of the present disclosure described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0029] Unless otherwise specified, the term "plurality" means two or more.

[0030] In the embodiments of the present disclosure, the character " / " indicates that the objects before and after are in an "or" relationship. For example, A / B means: A or B.

[0031] The term "and / or" is an associative relationship describing an object and indicates that three relationships can exist. For example, A and / or B means: A or B, or, A and B these three relationships.

[0032] In the embodiments of the present disclosure, when the temperature in the area where the air conditioner is located is relatively low while the humidity is very high, that is, when there is a need for low-temperature dehumidification, the low-temperature dehumidification function of the air conditioner can be activated, and the corresponding outdoor ambient temperature value at the start-up can be obtained. According to the outdoor ambient temperature value, the corresponding operating frequency of the compressor, the valve opening of the electronic expansion valve, the external wind speed of the outdoor fan, and the internal wind speed of the indoor fan are determined, etc. In this way, the dehumidification function of the air conditioner can be realized by controlling the compressor, the electronic expansion valve, the outdoor fan, and the indoor fan. Thus, it is possible to achieve low-temperature dehumidification without adding a reversing valve, and at the same time, the probability of environmental temperature fluctuations during the dehumidification process can be reduced, further improving the performance of the air conditioner. In addition, during the low-temperature dehumidification process of the air conditioner, the operation of the air conditioner compressor can be controlled according to the current indoor coil temperature, improving the dehumidification effect of the air conditioner and further enhancing the performance of the air conditioner.

[0033] Figure 1 It is a schematic flowchart of a method for controlling air conditioner dehumidification provided by the embodiments of the present disclosure. As Figure 1 shown, the process of air conditioner dehumidification control includes:

[0034] Step 101: When it is determined that the air conditioner starts to operate in the low-temperature dehumidification mode, obtain the current outdoor ambient temperature value in the area where the air conditioner is located.

[0035] According to the application scenario, the user can send a low-temperature dehumidification instruction through a remote controller or a terminal equipped with an APP. In this way, the air conditioner can receive the low-temperature dehumidification instruction and start to operate in the low-temperature dehumidification mode. Therefore, in some embodiments, when receiving the low-temperature dehumidification instruction, it is determined that the air conditioner starts to operate in the low-temperature dehumidification mode.

[0036] Of course, in some embodiments, when the air conditioner detects that the current indoor ambient temperature value in the area where it is located is less than the set temperature value and the current indoor ambient humidity value is greater than the set humidity value, it can also automatically start to operate in the low-temperature dehumidification mode. That is, when the current indoor ambient temperature value in the area where the air conditioner is located is less than the set temperature value and the current indoor ambient humidity value is greater than the set humidity value, it is determined that the air conditioner starts to operate in the low-temperature dehumidification mode. For example: when the air conditioner detects that the current indoor ambient temperature value is 15°C, less than the set temperature value of 16°C, and the current indoor humidity value is 75%, greater than the set humidity value of 70%, it can automatically start to operate in the low-temperature dehumidification mode.

[0037] In the embodiments of the present disclosure, when the air conditioner starts the low-temperature dehumidification mode, the current outdoor ambient temperature value in the area where the air conditioner is located can be obtained.

[0038] Step 102: Determine the current operating parameter values of the air conditioner that match the current outdoor ambient temperature value, where the operating parameter values include one or more of the operating frequency of the compressor, the valve opening of the electronic expansion valve, the external wind speed of the outdoor fan, and the internal wind speed of the indoor fan.

[0039] In the embodiments of the present disclosure, during the low-temperature dehumidification control process, the start and stop time of the indoor fan, the rotational speed of the outdoor fan, the operating frequency of the compressor, and the opening degree of the electronic expansion valve, etc. can be controlled, and one or more of them can be used to achieve low-temperature dehumidification and the normal operation of the machine. Moreover, in the low-temperature dehumidification mode, the operating parameter values of the air conditioner match the outdoor environmental temperature values.

[0040] Among them, in some embodiments, the current operating parameter values of the air conditioner that match the current outdoor environmental temperature value include: when the current outdoor environmental temperature value is greater than or equal to the first temperature value, determining the current operating frequency of the compressor as the first operating frequency, determining the opening degree of the front section valve of the periodically operating electronic expansion valve as the first valve opening degree, and the opening degree of the rear section valve as the second valve opening degree; when the current outdoor environmental temperature is less than the first temperature value, determining the current operating frequency of the compressor as the second operating frequency, determining the opening degree of the front section valve of the periodically operating electronic expansion valve as the third valve opening degree, and the opening degree of the rear section valve as the fourth valve opening degree; where the first operating frequency is greater than the second operating frequency, and the first valve opening degree is less than the third valve opening degree.

[0041] Table 1 is a corresponding relationship between the outdoor environmental temperature value and the operating frequency of the compressor provided by the embodiments of the present disclosure.

[0042] Outdoor ambient temperature value Tao Operating frequency f1 of the compressor Tao≥22°C index_self_clean_f1_1(90Hz) Tao<22°C index_self_clean_f1_2(85Hz)

[0043] Table 1

[0044] As shown in Table 1, the first temperature value is 22°C. If the current outdoor environmental temperature value is 15°C, which is less than 22°C, then according to Table 1, index_self_clean_f1_2 can be determined as the current operating frequency, that is, the second operating frequency is 85 hz. And if the current outdoor environmental temperature value is 25°C, which is greater than 22°C, then according to Table 1, index_self_clean_f1_1 can be determined as the current operating frequency, that is, the first operating frequency is 90 hz.

[0045] Table 2 shows the corresponding relationship between the outdoor ambient temperature value and the valve opening of the electronic expansion valve provided by the embodiments of the present disclosure. As shown in Table 2, the first temperature value is also 22°C. If the current outdoor ambient temperature value is 16°C, which is less than 22°C, then according to Table 2, the front-stage valve opening can be determined as the third valve opening, which is 35, and the rear-stage valve opening can be determined as the fourth valve opening, which is 230. If the current outdoor ambient temperature value is 23°C, which is greater than 22°C, then according to Table 2, the front-stage valve opening can be determined as the first valve opening, which is 34, and the rear-stage valve opening can be determined as the second valve opening, which is 230. In this embodiment, the second valve opening is the same as the fourth valve opening, but the embodiments of the present disclosure are not limited thereto. The first operating frequency, the second operating frequency, the first valve opening, the second valve opening, the third valve opening, and the fourth valve opening can all be determined according to the performance of the air conditioner, the geographical area where it is located, and the application season.

[0046]

[0047]

[0048] Table 2

[0049] Certainly, in some embodiments, the current external wind speed of the outdoor fan that matches the current outdoor ambient temperature value can also be determined, which may include: controlling the operation of the air conditioner according to the current operating frequency of the compressor and the current outdoor ambient temperature value, and after running for a set time, determining the current wind speed of the outdoor fan as the current external wind speed of the outdoor fan that matches the current outdoor ambient temperature value, that is, the first wind speed.

[0050] In some embodiments, the current internal wind speed of the indoor fan that matches the current outdoor ambient temperature value can also be determined, which may include: determining that the front-stage wind speed of the periodically operating indoor fan is the set low wind speed, and determining that the rear-stage wind speed of the periodically operating indoor fan is 0.

[0051] Step 103: Control the air conditioner to operate in the low-temperature dehumidification mode according to the current operating parameter values.

[0052] Among them, the operation of the air conditioner compressor can be controlled according to the current operating frequency of the compressor; the electronic expansion valve operates according to a set period. Among them, in each set period, within the first period of time, the electronic expansion valve operates according to the front-stage valve opening, and within the second period of time, the electronic expansion valve operates according to the rear-stage valve opening; and the indoor fan operates according to a set period. Among them, in each set period, within the first period of time, the indoor fan operates according to the set low wind speed, and within the second period of time, the indoor fan is controlled to stop.

[0053] Of course, the operation of the outdoor fan can also be controlled according to the first wind speed, where the first wind speed is the current wind speed of the outdoor fan after the air conditioner is controlled to operate for a set time according to the current operating frequency of the compressor and the current outdoor ambient temperature value.

[0054] Figure 2 It is a logical schematic diagram of air conditioner dehumidification control provided by an embodiment of the present disclosure. As Figure 2 shown, during the operation of the air conditioner in the low-temperature dehumidification mode, the compressor and the outdoor fan, i.e., the external fan, are in the on state, while the electronic expansion valve, i.e., the expansion valve, and the indoor fan, i.e., the internal fan, operate periodically with a set period of 15 minutes. Among them, the first period is 5 minutes, and the second period is 10 minutes. That is, within each 15-minute cycle, in the first 5 minutes, the valve opening of the electronic expansion valve is the front-section valve opening (the first valve opening or the third valve opening), and in the next 10 minutes, the valve opening of the electronic expansion valve is the rear-section valve opening (the second valve opening or the fourth valve opening). Moreover, within each 15-minute cycle, in the first 5 minutes, the rotational speed of the indoor fan is the set low wind speed. For example, the preset low gear wind speed of the air conditioner, and in the next 10 minutes, the indoor fan stops operating.

[0055] It can be seen that in this embodiment, the dehumidification function of the air conditioner can be realized by controlling the compressor, the electronic expansion valve, the outdoor fan, and the indoor fan. Thus, it is possible to achieve low-temperature dehumidification without adding a reversing valve. At the same time, it can also reduce the probability of environmental temperature fluctuations during the dehumidification process, further improving the performance of the air conditioner.

[0056] In some embodiments, when the air conditioner is in the low-temperature dehumidification mode, the operation of the compressor can be further controlled according to the indoor coil temperature, which may include: obtaining the current indoor coil temperature of the air conditioner operating in the low-temperature dehumidification mode; controlling the air conditioner compressor to operate at a reduced frequency when the current indoor coil temperature is less than the second temperature value; controlling the air conditioner compressor to operate at an increased frequency when the current indoor coil temperature is greater than the third temperature value; where the third temperature value is greater than the second temperature value.

[0057] For example: the second temperature value can be -15°C, and the third temperature value is -10°C. If the air conditioner is operating in the low-temperature dehumidification mode and the indoor coil temperature is obtained in real time or at regular intervals, if the obtained current indoor coil temperature is -18°C, which is less than -15°C, the compressor can be controlled to operate at a reduced frequency at a rate of 1 Hz / 10 s. Of course, if the operating frequency after the reduction is less than the preset minimum operating frequency of the air conditioner compressor, the preset minimum operating frequency can be determined as the operating frequency after the reduction for the operation of the air conditioner compressor. If the obtained current indoor coil temperature is -5°C, which is greater than -10°C, the compressor can be controlled to operate at an increased frequency at a rate of 1 Hz / 10 s.

[0058] Of course, in the embodiments of the present disclosure, the up - frequency operation or down - frequency operation is not limited to this. It can also increase or decrease the set value each time for up - frequency operation or down - frequency operation, and specific examples will not be listed one by one.

[0059] In this way, during the low - temperature dehumidification process of the air conditioner, the operation of the air - conditioner compressor can also be controlled according to the current indoor coil temperature, improving the dehumidification effect of the air conditioner and further enhancing the performance of the air conditioner.

[0060] Next, the operation process will be incorporated into specific embodiments to illustrate the air - conditioner dehumidification control process provided by the embodiments of the present invention.

[0061] In an embodiment of the present disclosure, the air conditioner stores the corresponding relationships shown in Table 1 and Table 2. Among them, the first temperature value is 22 °C. And the stored second temperature value can be - 15 °C, and the third temperature value is - 10 °C.

[0062] Figure 3 It is a schematic flow chart of a method for air - conditioner dehumidification control provided by the embodiments of the present disclosure.

[0063] Combined with Figure 3 , the air - conditioner dehumidification control process includes:

[0064] Step 301: Determine whether a low - temperature dehumidification instruction is received? If yes, execute Step 302; otherwise, return to Step 301.

[0065] The user determines the low - temperature dehumidification mode through the mode selection on the remote control, thereby sending a low - temperature dehumidification instruction.

[0066] Step 302: Obtain the current outdoor ambient temperature value of the area where the air conditioner is located.

[0067] Step 303: According to Table 1 and Table 2, determine the current operating frequency of the compressor that matches the current outdoor ambient temperature value, as well as the opening degrees of the front - stage valve and the rear - stage valve of the electronic expansion valve.

[0068] Step 304: Control the operation of the air - conditioner compressor according to the current operating frequency of the compressor.

[0069] Step 305: Operate the electronic expansion valve according to the set period. Among them, within each set period, in the first period of time, operate the electronic expansion valve according to the opening degree of the front - stage valve, and in the second period of time, operate the electronic expansion valve according to the opening degree of the rear - stage valve. And operate the indoor fan according to the set period. Among them, within each set period, in the first period of time, operate the indoor fan according to the set low wind speed, and in the second period of time, control the indoor fan to stop.

[0070] Step 306: Control the operation of the outdoor fan according to the first wind speed, where the first wind speed is the current wind speed of the outdoor fan after controlling the air conditioner to operate for a set time according to the current operating frequency of the compressor and the current outdoor ambient temperature value.

[0071] Steps 303, 304, 305, and 306 run synchronously.

[0072] Step 307: Obtain the current indoor coil temperature of the air conditioner operating in the low-temperature dehumidification mode.

[0073] Step 308: Determine whether the current indoor coil temperature < -15°C holds. If so, execute Step 309; otherwise, execute Step 311.

[0074] Step 309: Perform a frequency reduction process on the current operating frequency of the compressor at a frequency reduction rate of 1 Hz / 10 s to obtain the reduced operating frequency of the compressor.

[0075] Step 310: Control the operation of the air conditioner compressor according to the larger value between the preset minimum operating frequency and the reduced operating frequency of the compressor, and transfer to Step 314.

[0076] Step 311: Determine whether the current indoor coil temperature > -10°C holds. If so, execute Step 312; otherwise, execute Step 314.

[0077] Step 312: Perform a frequency increase process on the current operating frequency of the compressor at a frequency increase rate of 1 Hz / 10 s to obtain the increased operating frequency of the compressor.

[0078] Step 313: Control the operation of the air conditioner compressor according to the increased operating frequency of the compressor, and transfer to Step 314.

[0079] Step 314: Is an instruction to exit the low-temperature dehumidification mode received? If so, the process ends; otherwise, return to Step 307.

[0080] The user can confirm receiving the instruction to exit the low-temperature dehumidification mode by sending a mode switching instruction or a shutdown instruction through the remote control, and the process ends.

[0081] It can be seen that in this embodiment, after the air conditioner starts the low-temperature dehumidification mode, the outdoor ambient temperature value corresponding to the startup can be obtained, and according to the outdoor ambient temperature value, the operating frequency of the corresponding compressor, the valve opening of the electronic expansion valve, the external wind speed of the outdoor fan, and the internal wind speed of the indoor fan can be determined. In this way, the dehumidification function of the air conditioner can be realized by controlling the compressor, the electronic expansion valve, the outdoor fan, and the indoor fan. Therefore, without adding a reversing valve, low-temperature dehumidification can be achieved, and at the same time, the probability of environmental temperature fluctuations during the dehumidification process can be reduced, further improving the performance of the air conditioner. In addition, during the low-temperature dehumidification process of the air conditioner, the operation of the air conditioner compressor can be controlled according to the current indoor coil temperature, improving the dehumidification effect of the air conditioner and further enhancing the performance of the air conditioner.

[0082] According to the above process for air conditioner dehumidification control, a device for air conditioner dehumidification control can be constructed.

[0083] Figure 4 It is a schematic structural diagram of a device for air conditioner dehumidification control provided by an embodiment of the present disclosure. As Figure 4 shown, the device for air conditioner dehumidification control includes: a first acquisition module 410, a parameter determination module 420, and a first control module 430.

[0084] The first acquisition module 410 is configured to obtain the current outdoor ambient temperature value of the area where the air conditioner is located when it is determined that the air conditioner starts to operate in the low-temperature dehumidification mode.

[0085] The parameter determination module 420 is configured to determine the operating parameter values of the air conditioner that match the current outdoor ambient temperature value, where the operating parameter values include one or more of the compressor operating frequency, the electronic expansion valve opening, the outdoor fan wind speed, and the indoor fan wind speed.

[0086] The first control module 430 is configured to control the air conditioner to operate in the low-temperature dehumidification mode according to the current operating parameter values.

[0087] In some embodiments, the first acquisition module 410 includes:

[0088] The first determination unit is configured to determine that the air conditioner starts to operate in the low-temperature dehumidification mode when a low-temperature dehumidification instruction is received.

[0089] The second determination unit is configured to determine that the air conditioner starts to operate in the low-temperature dehumidification mode when the current indoor ambient temperature value in the area where the air conditioner is located is less than the set temperature value and the current indoor ambient humidity value is greater than the set humidity value.

[0090] In some embodiments, the parameter determination module 420 includes:

[0091] The first parameter determination unit is configured to, when the current outdoor ambient temperature value is greater than or equal to the first temperature value, determine the current operating frequency of the compressor as the first operating frequency, determine the opening of the front-stage valve of the periodically operating electronic expansion valve as the first valve opening, and the opening of the rear-stage valve as the second valve opening.

[0092] The second parameter determination unit is configured to, when the current outdoor ambient temperature is less than the first temperature value, determine the current operating frequency of the compressor as the second operating frequency, determine the opening of the front-stage valve of the periodically operating electronic expansion valve as the third valve opening, and the opening of the rear-stage valve as the fourth valve opening.

[0093] Wherein, the first operating frequency is greater than the second operating frequency, and the first valve opening is less than the third valve opening.

[0094] In some embodiments, the first control module 430 is specifically configured to control the operation of the air-conditioning compressor according to the current operating frequency of the compressor; operate the electronic expansion valve according to the set period, wherein, in each set period, in the first period of time, operate the electronic expansion valve according to the opening of the front-stage valve, and in the second period of time, operate the electronic expansion valve according to the opening of the rear-stage valve; operate the indoor blower according to the set period, wherein, in each set period, in the first period of time, operate the indoor blower according to the set low wind speed, and in the second period of time, control the indoor blower to stop.

[0095] In some embodiments, the first control module is further configured to control the operation of the outdoor blower according to the first wind speed, wherein the first wind speed is the current wind speed of the outdoor blower after controlling the operation of the air conditioner for a set time according to the current operating frequency of the compressor and the current outdoor ambient temperature value.

[0096] In some embodiments, it further includes: a second control module, configured to obtain the current indoor coil temperature of the air conditioner operating in the low-temperature dehumidification mode; when the current indoor coil temperature is less than the second temperature value, control the air-conditioning compressor to operate at a reduced frequency; when the current indoor coil temperature is greater than the third temperature value, control the air-conditioning compressor to operate at an increased frequency; wherein, the third temperature value is greater than the second temperature value.

[0097] The air-conditioning dehumidification control process for the air-conditioning dehumidification control device will be further described below in conjunction with embodiments.

[0098] In this embodiment, the air conditioner stores the corresponding relationships shown in Table 1 and Table 2, wherein the first temperature value is 22 °C. And, the stored second temperature value can be -16 °C, and the third temperature value is -12 °C.

[0099] Figure 5 is a schematic structural diagram of an air-conditioning dehumidification control device provided by an embodiment of the present disclosure. As Figure 5As shown, the air-conditioning dehumidification control device includes: a first acquisition module 410, a parameter determination module 420, a first control module 430, and a second control module 440. Moreover, the first acquisition module 410 includes: a first determination unit 411.

[0100] In this way, after receiving the low-temperature dehumidification instruction, the first determination unit 411 can determine that the air conditioner starts to operate in the low-temperature dehumidification mode. Thus, the first acquisition module 410 can acquire the current outdoor ambient temperature value of the area where the air conditioner is located.

[0101] In this way, the parameter determination module 420 can determine the current operating frequency of the compressor, the opening degree of the front-stage valve, and the opening degree of the rear-stage valve that match the current outdoor ambient temperature value according to Table 1 and Table 2. Thus, the first control module 430 can control the operation of the air-conditioning compressor respectively according to the current operating frequency of the compressor, operate the electronic expansion valve according to the set period. Among them, in each set period, in the first period of time, the electronic expansion valve is operated according to the opening degree of the front-stage valve, and in the second period of time, the electronic expansion valve is operated according to the opening degree of the rear-stage valve, and operate the indoor fan according to the set period. Among them, in each set period, in the first period of time, the indoor fan is operated according to the set low wind speed, and in the second period of time, the indoor fan is controlled to stop. Of course, the first control module 430 can also control the operation of the outdoor fan according to the first wind speed, where the first wind speed is the current wind speed of the outdoor fan after the air conditioner operates for a set time according to the current operating frequency of the compressor and the current outdoor ambient temperature value.

[0102] During the operation of the air conditioner in the low-temperature dehumidification mode, the current indoor coil temperature of the air conditioner operating in the low-temperature dehumidification mode can be acquired. Moreover, when the current indoor coil temperature < -16°C, the second control module 440 can perform a frequency reduction process on the current operating frequency of the compressor at a frequency reduction speed of 1 Hz / 10 s to obtain the reduced operating frequency of the compressor, and control the operation of the air-conditioning compressor according to the larger value of the reduced operating frequency of the compressor and the preset minimum operating frequency. If the current indoor coil temperature > -12°C, the second control module 440 can perform a frequency increase process on the current operating frequency of the compressor at a frequency increase speed of 1 Hz / 10 s to obtain the increased operating frequency of the compressor, and control the operation of the air-conditioning compressor according to the increased operating frequency of the compressor.

[0103] It can be seen that in this embodiment, after the air conditioner starts the low-temperature dehumidification mode, the device for air conditioner dehumidification control can obtain the corresponding outdoor ambient temperature value at startup, and determine the corresponding operating frequency of the compressor, the valve opening of the electronic expansion valve, the external wind speed of the outdoor fan, and the internal wind speed of the indoor fan according to the outdoor ambient temperature value. In this way, the dehumidification function of the air conditioner can be realized by controlling the compressor, the electronic expansion valve, the outdoor fan, and the indoor fan. Therefore, it is possible to achieve low-temperature dehumidification without adding a reversing valve, and at the same time, the probability of environmental temperature fluctuation during dehumidification can be reduced, further improving the performance of the air conditioner. In addition, during the low-temperature dehumidification process of the air conditioner, the operation of the air conditioner compressor can also be controlled according to the current indoor coil temperature, improving the dehumidification effect of the air conditioner and further enhancing the performance of the air conditioner.
