[0038] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0039] The terms "first", "second", etc. in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0040] Unless otherwise stated, the term "plurality" means two or more.

[0041] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0042] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0043] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0044] In the air conditioner system, there is usually a dehumidification function. When the indoor humidity is high, the dehumidification mode can be operated. The humid air in the room is sucked into the air conditioner through the fan. After the moisture in the air is condensed into water when passing through the evaporator, the dehumidified air is sent back into the room through the air outlet of the air conditioner to achieve the dehumidification effect. In addition, during the dehumidification process, due to the heat exchange between the indoor air and the evaporator, the indoor ambient temperature will be in a low temperature state, which may affect the user experience. In the related technology, for different indoor ambient temperatures, the air conditioner can be adjusted to the preset operating parameters for dehumidification. However, when the air humidity is particularly high, such as in the rainy season, the air humidity will reach more than 90%. At this time, if the air conditioner dehumidification mode is adjusted only in a fixed gear, it is often impossible to achieve the best dehumidification effect.

[0045] Combination Figure 1 As shown, in the embodiment of the present disclosure, the air conditioner includes a detection sensor 10, a processor 20, a compressor 30 and an indoor fan 40. The detection sensor 10 includes a temperature detection sensor for detecting indoor ambient temperature, outdoor ambient temperature and indoor coil temperature, and a humidity detection sensor for detecting indoor ambient humidity. The processor 20 is used to receive various parameters detected by the detection sensor and give control instructions to adjust the operating frequency of the compressor 30 and the speed of the indoor fan 40.

[0046] The disclosed embodiment provides a method for dehumidifying an air conditioner, wherein when the air conditioner enters the dehumidification mode, the processor of the air conditioner determines the range of the rotation speed of the indoor fan and the operating frequency of the compressor according to the indoor ambient temperature. Then, according to the changes of various parameters, the processor adjusts the range of the rotation speed of the indoor fan and the operating frequency of the compressor in real time, thereby adjusting the dehumidification effect and the cooling effect of the air conditioner.

[0047] Combination Figure 2 As shown, the method for dehumidifying an air conditioner provided by the embodiment of the present disclosure includes:

[0048] S001, the processor obtains the indoor ambient temperature when the air conditioner enters the dehumidification mode.

[0049] S002: The processor determines the range of the rotation speed of the indoor fan and the operating frequency of the compressor according to the indoor ambient temperature.

[0050] S003, the processor adjusts the speed of the indoor fan and / or adjusts the range of the compressor operating frequency.

[0051] After the air conditioner enters the dehumidification mode, the processor obtains the indoor ambient temperature and determines the range of the indoor fan speed and compressor operating frequency based on the indoor ambient temperature. After determining the initial value, the range of the indoor fan speed and compressor operating frequency can be adjusted in time so that the air conditioner can always operate in the most efficient dehumidification mode. In addition, by adjusting the indoor fan speed and compressor frequency, the air conditioner can reduce the fluctuation range of the indoor ambient temperature while maintaining a good dehumidification effect.

[0052] Optionally, according to the indoor ambient temperature, the range of the indoor fan speed and the compressor operating frequency is determined, including: when Tr>Ts+a, the indoor fan speed is determined to be N1, and the maximum operating frequency of the compressor is F1; when Ts+a≥Tr>Ts+b, the indoor fan speed is determined to be N2, and the maximum operating frequency of the compressor is F2; ​​when Tr≤Ts+b, the indoor fan speed is determined to be N3, the maximum operating frequency of the compressor is F2, and the minimum operating frequency is F3.

[0053] Among them, Tr is the indoor ambient temperature; Ts is the first temperature threshold; a is the first threshold; N1 is the first preset speed; F1 is the first preset frequency; b is the second threshold; N2 is the second preset speed; F2 is the second preset frequency; N3 is the third preset speed; F3 is the third preset frequency; a>b; N1>N2>N3; F1>F2>F3.

[0054] After the air conditioner enters the dehumidification mode, it will determine different ranges of indoor fan speed and compressor operating frequency according to different indoor ambient temperatures, so that the air conditioner can achieve the best dehumidification effect at the indoor ambient temperature. When the indoor ambient temperature is high, the air conditioner is in a higher speed and higher frequency operation state, which can achieve the effect of cooling and dehumidification. When the indoor ambient temperature is low, the air conditioner will be in a lower speed and lower frequency operation state, so that the indoor ambient temperature remains near the first temperature threshold, reducing the situation where the air conditioner makes the indoor ambient temperature too low in the dehumidification mode.

[0055] Optionally, the value range of a is [3°C, 4°C]. More specifically, a=3°C, 3.5°C or 4°C.

[0056] Optionally, the value range of b is [1.5°C, 2.5°C]. More specifically, b=1.5°C, 2°C or 2.5°C.

[0057] Optionally, the value range of N1 is [900 r / min, 1100 r / min]. More specifically, N1=950 r / min, 1000 r / min or 1050 r / min.

[0058] Optionally, the value range of F1 is [100 Hz, 110 Hz]. More specifically, F1 = 100 Hz, 105 Hz or 110 Hz.

[0059] Optionally, the value range of N2 is [700 r / min, 800 r / min]. More specifically, N2=700 r / min, 750 r / min or 800 r / min.

[0060] Optionally, the value range of F2 is [80 Hz, 90 Hz]. More specifically, F2 = 80 Hz, 85 Hz or 90 Hz.

[0061] Optionally, the value range of N3 is [550 r / min, 650 r / min]. More specifically, N3=550 r / min, 600 r / min or 650 r / min.

[0062] Optionally, the value range of F3 is [15 Hz, 20 Hz]. More specifically, F3 = 15 Hz, 17 Hz or 20 Hz.

[0063] According to different actual conditions, the above-mentioned value range can be adjusted accordingly so that the air conditioner can operate at an indoor fan speed and compressor operating frequency with more efficient dehumidification performance under different indoor ambient temperature ranges.

[0064] Optionally, the method further comprises: in the case of Tr≤Ts+b, determining the initial operating frequency of the compressor to be F4, wherein F4 is the average value of F2 and F3.

[0065] When Tr≤Ts+b, the air conditioner can realize the linkage adjustment of indoor ambient temperature and indoor ambient humidity by adjusting the indoor fan speed and the operating frequency of the compressor, thereby reducing the fluctuation range of indoor ambient temperature during the dehumidification process while lowering the indoor ambient humidity.

[0066] In dehumidification mode, the indoor air will exchange heat with the air conditioner's heat exchanger, lowering the indoor ambient temperature. However, in different situations, the user's needs may not include lowering the indoor ambient temperature, so the air conditioner needs to reduce the indoor ambient humidity while keeping the indoor ambient temperature from fluctuating too much. At this time, the air conditioner can operate in the temperature and humidity dual control mode, and adjust the temperature and humidity in a linked manner, which can not only achieve a good dehumidification effect, but also keep the indoor ambient temperature near the preset temperature threshold.

[0067] Optionally, after the air conditioner enters the temperature and humidity dual control mode, the speed of the indoor fan is adjusted according to the real-time operating frequency of the compressor.

[0068] In this embodiment, after the air conditioner enters the temperature and humidity dual control mode, it is necessary to synchronously adjust the speed of the indoor fan according to the real-time operating frequency of the compressor to achieve linkage adjustment of temperature and humidity.

[0069] In practical applications, the operating frequency range of the air conditioner compressor is usually [10Hz, 130Hz], and the range of the indoor fan speed is usually [300r / min, 1200r / min]. Therefore, the operating frequency range of the air conditioner compressor can be corresponded to the range of the indoor fan speed, and then the indoor fan speed can be adjusted according to the real-time operating frequency of the compressor. More specifically, when the compressor operating frequency is below 40Hz, the indoor fan speed is adjusted to 400r / min; when the compressor operating frequency is between 40Hz and 45Hz, the indoor fan speed is adjusted to 500r / min; when the compressor operating frequency is between 45Hz and 50Hz, the indoor fan speed is adjusted to 600r / min; when the compressor operating frequency is between 50Hz and 55Hz, the indoor fan speed is adjusted to 700r / min; when the compressor operating frequency is between 55Hz and 60Hz, the indoor fan speed is adjusted to 800r / min; when the compressor operating frequency is above 60Hz, the indoor fan speed is adjusted to 1000r / min.

[0070] Optionally, after adjusting the indoor fan speed according to the real-time operating frequency of the compressor, if the compressor operating frequency changes within a first time threshold, the indoor fan maintains the current speed unchanged, and the fan speed is readjusted according to the compressor operating frequency after reaching the first time threshold.

[0071] Optionally, the value range of the first time threshold t1' is [2 min, 3 min]. More specifically, t1'=2 min, 2.5 min or 3 min.

[0072] In order to reduce the situation where the indoor fan speed changes multiple times in a short period of time due to fluctuations in the compressor operating frequency, a first time threshold can be set. After the indoor fan speed changes, the current speed is maintained for the first time threshold, and then the fan speed is readjusted according to the compressor operating frequency.

[0073] Optionally, after the air conditioner enters the temperature and humidity dual control mode, when Tr<Ts-z, the air conditioner is turned off; when Tr>Ts-z, the air conditioner is turned on.

[0074] After the air conditioner enters the dehumidification mode, the indoor ambient temperature will gradually decrease as the dehumidification mode runs. When the temperature is too low, the air conditioner can be turned off in time to reduce the occurrence of low temperature.

[0075] Optionally, the value range of z is [2°C, 4°C]. More specifically, z=2°C, 3°C or 4°C.

[0076] Optionally, adjusting the indoor fan speed includes: adjusting the indoor fan speed according to the indoor ambient temperature or the indoor coil temperature.

[0077] By detecting the indoor ambient temperature or the indoor coil temperature, the level of the indoor ambient temperature can be directly or indirectly reflected, and the fan speed can be adjusted accordingly to reasonably control the indoor ambient temperature.

[0078] Optionally, the indoor fan speed is adjusted according to the indoor ambient temperature or the indoor coil temperature, including: when the duration of Tr≤Ts-c reaches a first preset duration, the indoor fan speed is increased by ω1; or, when the duration of Tp<T1 reaches a first preset duration, the indoor fan speed is increased by ω1.

[0079] Wherein, c is the third threshold value; ω1 is the first modified rotation speed; Tp is the indoor coil temperature; and T1 is the second temperature threshold value.

[0080] When the indoor ambient temperature is lower than the first temperature threshold, or the indoor coil temperature is lower than the second temperature threshold, the indoor ambient temperature may be lower than the user's expectation. In this case, the indoor ambient temperature can be adjusted by increasing the fan speed.

[0081] Optionally, the value range of c is [0.5°C, 1.5°C]. More specifically, c=0.5°C, 1°C or 1.5°C.

[0082] Optionally, the value range of ω1 is [80 r / min, 100 r / min]. More specifically, ω1=80 r / min, 90 r / min or 100 r / min.

[0083] Optionally, the value range of T1 is [11°C, 13°C]. More specifically, T1 = 11°C, 12°C or 13°C.

[0084] Optionally, the value range of the first preset time length t1 is [1 min, 2 min]. More specifically, t1 = 1 min, 1.5 min or 2 min.

[0085] Optionally, adjusting the indoor fan speed and adjusting the range of the compressor operating frequency include: adjusting the maximum operating frequency of the compressor and the indoor fan speed according to the indoor ambient temperature and the indoor ambient humidity.

[0086] In dehumidification mode, the indoor humidity will gradually decrease, and even far below the preset humidity. At this time, it is necessary to adjust the maximum operating frequency of the compressor and the speed of the indoor fan to reduce the problem of excessive dryness of the indoor air.

[0087] Optionally, the maximum operating frequency of the compressor and the indoor fan speed are adjusted according to the indoor ambient temperature and the indoor ambient humidity, including: when the duration of Tr≤Ts+d and x≤Rhs-Rh<y reaches a second preset time length, the maximum operating frequency of the compressor is reduced by f1, and the indoor fan speed is increased by ω2; or, when the duration of Tr≤Ts+d and Rhs-Rh≥y reaches a second preset time length, the maximum operating frequency of the compressor is reduced by f2, and the indoor fan speed is increased by ω3.

[0088] Among them, d is the fourth threshold; Rhs is the first humidity threshold; Rh is the indoor ambient humidity; x is the fifth threshold; y is the sixth threshold; f1 is the first correction frequency; ω2 is the second correction speed; f2 is the second correction frequency; ω3 is the third correction speed; x<y; f1<f2; ω2<ω3.

[0089] In the case of Tr>Ts+d, it means that the indoor ambient temperature is high at this time, and the air conditioner can operate in dehumidification mode to reduce the indoor ambient humidity and temperature. In the case of Tr≤Ts+d, when the indoor ambient humidity is much lower than the set humidity, the dehumidification effect of the air conditioner can be reduced by adjusting the speed of the indoor fan and the maximum operating frequency of the compressor, so that the indoor ambient humidity can be kept near the set humidity.

[0090] Optionally, the value range of d is [4°C, 5°C]. More specifically, d=4°C, 4.5°C or 5°C.

[0091] Optionally, the value range of Rhs is [45%, 55%]. More specifically, Rhs=47%, 50% or 52%.

[0092] Optionally, the value range of x is [5%, 8%]. More specifically, x=5%, 6% or 7%.

[0093] Optionally, the value range of y is [13%, 17%]. More specifically, y=13%, 15% or 16%.

[0094] Optionally, the value range of f1 is [9 Hz, 13 Hz]. More specifically, f1 = 9 Hz, 10 Hz or 12 Hz.

[0095] Optionally, the value range of f2 is [15 Hz, 18 Hz]. More specifically, f2 = 15 Hz, 16 Hz or 17 Hz.

[0096] Optionally, the value range of ω2 is [80 r / min, 100 r / min]. More specifically, ω2=80 r / min, 90 r / min or 100 r / min.

[0097] Optionally, the value range of ω3 is [130 r / min, 160 r / min]. More specifically, ω3=130 r / min, 150 r / min or 160 r / min.

[0098] Optionally, the value range of the second preset time length t2 is [1 min, 2 min]. More specifically, t1 = 1 min, 1.5 min or 2 min.

[0099] Optionally, adjusting the range of the compressor operating frequency includes: adjusting the minimum compressor operating frequency according to indoor ambient humidity or outdoor ambient temperature.

[0100] Optionally, the minimum operating frequency of the compressor is adjusted according to the indoor ambient humidity or the outdoor ambient temperature, including: when the duration of Rhs-Rh≥x reaches a third preset duration, the minimum operating frequency of the compressor is set to F5; or, when Rhs-Rh<x and T2≤To≤T3, the minimum operating frequency of the compressor is set to F6; or, when Rhs-Rh<x and T4≤To≤T2, the minimum operating frequency of the compressor is set to F7.

[0101] Among them, Rhs is the first humidity threshold; Rh is the indoor ambient humidity; x is the fifth threshold; F5 is the fourth preset frequency; To is the outdoor ambient temperature; T2 is the third temperature threshold; T3 is the fourth temperature threshold; T4 is the fifth temperature threshold; F6 is the fifth preset frequency; F7 is the sixth preset frequency; T4<T2<T3; F6>F7.

[0102] When the indoor humidity is low or the outdoor temperature is low, the dehumidification effect of the air conditioner can be adjusted by adjusting the minimum frequency of the compressor to further keep the indoor humidity near the set humidity. In addition, when the outdoor temperature range changes, the minimum operating frequency of the compressor needs to be maintained for a second time threshold before the minimum operating frequency can be changed. When the air conditioner is shut down and turned on again, the initial frequency of the compressor is fixed to F3.

[0103] Optionally, the value range of F5 is [10 Hz, 25 Hz]. More specifically, F5=10 Hz, 12 Hz or 14 Hz.

[0104] Optionally, the value range of F6 is [27 Hz, 29 Hz]. More specifically, F6 = 27 Hz, 28 Hz or 29 Hz.

[0105] Optionally, the value range of F7 is [23 Hz, 25 Hz]. More specifically, F7 = 23 Hz, 24 Hz or 25 Hz.

[0106] Optionally, the value range of T3 is [30°C, 34°C]. More specifically, T3=31°C, 32°C or 33°C.

[0107] Optionally, the value range of T2 is [24°C, 26°C]. More specifically, T2 = 24°C, 25°C or 26°C.

[0108] Optionally, the value range of T4 is [18°C, 22°C]. More specifically, T4=19°C, 20°C or 21°C.

[0109] Optionally, the value range of the third preset time length t3 is [2 min, 4 min]. More specifically, t1 = 2 min, 3 min or 4 min.

[0110] Optionally, the value range of the second time threshold t2' is [2 min, 3 min]. More specifically, t1'=2 min, 2.5 min or 3 min.

[0111] Optionally, when the air conditioner just enters the dehumidification mode, the method further includes: calculating a first temperature threshold.

[0112] Combination Figure 3 As shown, the embodiment of the present disclosure provides another method for dehumidifying an air conditioner, comprising:

[0113] S101, when the processor just enters the dehumidification mode, sets a first temperature threshold.

[0114] S102: The processor obtains the indoor ambient temperature.

[0115] S103: The processor determines the range of the rotation speed of the indoor fan and the operating frequency of the compressor according to the indoor ambient temperature and the first temperature threshold.

[0116] S104: The processor adjusts the speed of the indoor fan and / or adjusts the range of the operating frequency of the compressor.

[0117] By setting the first temperature threshold, the real-time temperature of the indoor environment can be compared with the first temperature threshold, and the appropriate indoor fan speed and compressor frequency can be adjusted so that the indoor environment temperature can be maintained near the first temperature threshold, thereby reducing the extent of the indoor environment temperature drop due to running the cooling mode.

[0118] Optionally, setting the first temperature threshold includes: calculating Ts=Tr0+M to obtain the first temperature threshold Ts.

[0119] Wherein, Tr0 is the indoor ambient temperature when the air conditioner just enters the dehumidification mode, and M is a preset constant value.

[0120] Optionally, the value range of M is [-3°C, 1°C]. More specifically, M=-2°C, -1°C, 0.

[0121] In different actual situations and user needs, different first temperature thresholds can be selected to make the indoor ambient temperature in the dehumidification mode more in line with user expectations.

[0122] Optionally, the method further includes: when Tr<Ts+e and To≤T5, turning on the electric heating device; when the duration of Tr≥Ts+b reaches a fourth preset time or the indoor fan is turned off, turning off the electric heating device.

[0123] Among them, Tr is the indoor ambient temperature; Ts is the first temperature threshold; e is the fifth threshold; To is the outdoor ambient temperature; T5 is the sixth temperature threshold; b is the second threshold; b>e.

[0124] Combination Figure 4 As shown, the embodiment of the present disclosure provides another method for dehumidifying an air conditioner, comprising:

[0125] S201: When the processor just enters the dehumidification mode, it calculates the first temperature threshold.

[0126] S202: The processor obtains the indoor ambient temperature.

[0127] S203: The processor determines the range of the rotation speed of the indoor fan and the operating frequency of the compressor according to the indoor ambient temperature and the first temperature threshold.

[0128] S204: The processor adjusts the speed of the indoor fan and / or adjusts the range of the operating frequency of the compressor.

[0129] S205: When Tr<Ts+e and To≤T5, the processor turns on the electric heating device.

[0130] S206: When the duration of Tr≥Ts+b reaches a fourth preset duration or the indoor fan is turned off, the processor turns off the electric heating device.

[0131] When the air conditioner is in dehumidification mode, the indoor ambient temperature will continue to decrease due to the heat exchange between the indoor air and the air conditioner heat exchanger. If the user does not need to cool down at this time, the indoor ambient temperature can be increased by electric heating. In addition, when turning the electric heating on and off, it is also necessary to turn the electric heating off after the electric heating remains on for a third time threshold; or turn the electric heating on after the electric heating remains off for a fourth time threshold.

[0132] Optionally, the value range of e is [1°C, 1.5°C]. More specifically, a=1°C, 1.2°C or 1.4°C.

[0133] Optionally, the value range of T5 is [33°C, 35°C]. More specifically, a=33°C, 34°C or 35°C.

[0134] Optionally, the value range of the fourth preset time length t4 is [1 min, 2 min]. More specifically, t1 = 1 min, 1.5 min or 2 min.

[0135] Optionally, the value range of the third time threshold t3' is [25 min, 35 min]. More specifically, t3'=25 min, 30 min or 35 min.

[0136] Optionally, the value range of the fourth time threshold t4' is [4 min, 6 min]. More specifically, t4'=4 min, 5 min or 6 min.
