The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0042] The term "and / or" describes an association 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" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0044] Air conditioning systems typically include a dehumidification function. When indoor humidity is high, the dehumidification mode is activated. A fan draws humid indoor air into the air conditioner, where the moisture is condensed into water as it passes through the evaporator. This dehumidified air is then returned to the room through the air conditioner's outlet, achieving the desired dehumidification effect. However, during dehumidification, the heat exchange between the indoor air and the evaporator can lower the indoor temperature, potentially affecting user experience. Related technologies allow air conditioners to be adjusted to preset operating parameters for different indoor temperatures. However, in extremely high humidity conditions, such as during the rainy season when humidity levels can exceed 90%, using a fixed dehumidification setting often fails to achieve optimal dehumidification results.

[0045] Combination Figure 1 As shown, in this 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 sensor for detecting indoor ambient temperature, outdoor ambient temperature, and indoor coil temperature, and a humidity sensor for detecting indoor ambient humidity. The processor 20 is used to receive various parameters detected by the detection sensors and issue control commands to adjust the operating frequency of the compressor 30 and the rotation speed of the indoor fan 40.

[0046] This disclosure provides a method for dehumidifying an air conditioner. When the air conditioner is in dehumidification mode, its processor determines the range of indoor fan speed and compressor operating frequency based on the indoor ambient temperature. Then, based on changes in various parameters, the processor adjusts the range of indoor fan speed and compressor operating frequency in real time, thereby adjusting the air conditioner's dehumidification and cooling effects.

[0047] Combination Figure 2 As shown in the embodiments of this disclosure, the method for dehumidifying an air conditioner includes:

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

[0049] S002, the processor determines the range of indoor fan speed and compressor operating frequency based on the indoor ambient temperature.

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

[0051] After the air conditioner enters dehumidification mode, the processor acquires the indoor ambient temperature and determines the range of indoor fan speed and compressor operating frequency based on this temperature. After determining the initial values, it can promptly adjust the range of indoor fan speed and compressor operating frequency, ensuring the air conditioner always operates in the most efficient dehumidification mode. Furthermore, by adjusting the indoor fan speed and compressor frequency, the air conditioner can reduce fluctuations in indoor ambient temperature while maintaining good dehumidification performance.

[0052] Optionally, the range of indoor fan speed and compressor operating frequency is determined based on the indoor ambient temperature, 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] Where Tr is the indoor ambient temperature; Ts is the first temperature threshold; a is the first threshold; N1 is the first preset rotation speed; F1 is the first preset frequency; b is the second threshold; N2 is the second preset rotation speed; F2 is the second preset frequency; N3 is the third preset rotation speed; F3 is the third preset frequency; a > b; N1 > N2 > N3; F1 > F2 > F3.

[0054] When an air conditioner enters dehumidification mode, it adjusts the indoor fan speed and compressor operating frequency based on the ambient temperature to achieve optimal dehumidification. When the indoor temperature is high, the air conditioner operates at a higher speed and frequency to achieve cooling and dehumidification. Conversely, when the indoor temperature is low, the air conditioner operates at a lower speed and frequency to maintain the indoor temperature near the first temperature threshold, reducing the likelihood of the indoor temperature dropping too low during dehumidification.

[0055] Optionally, the value of a can be [3℃, 4℃]. More specifically, a = 3℃, 3.5℃, or 4℃.

[0056] Optionally, the value of b can be in the range of [1.5℃, 2.5℃]. More specifically, b = 1.5℃, 2℃, or 2.5℃.

[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 [100Hz, 110Hz]. More specifically, F1 = 100Hz, 105Hz, or 110Hz.

[0059] Optionally, the value of N2 can be in the range of [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 [80Hz, 90Hz]. More specifically, F2 = 80Hz, 85Hz, or 90Hz.

[0061] Optionally, the value of N3 can be in the range of [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 [15Hz, 20Hz]. More specifically, F3 = 15Hz, 17Hz, or 20Hz.

[0063] Depending on the specific circumstances, the above value range can be adjusted accordingly, allowing the air conditioner to operate at a more efficient indoor fan speed and compressor operating frequency under different indoor ambient temperature ranges.

[0064] Optionally, the method further includes: determining the initial operating frequency of the compressor as F4 when Tr≤Ts+b. Here, F4 is the average of F2 and F3.

[0065] When Tr≤Ts+b, the air conditioner can adjust the indoor fan speed and the compressor operating frequency to achieve coordinated regulation of indoor ambient temperature and humidity, thereby reducing indoor ambient humidity and minimizing the fluctuation of indoor ambient temperature during the dehumidification process.

[0066] In dehumidification mode, indoor air exchanges heat with the air conditioner's heat exchanger, lowering the indoor temperature. However, in different situations, users may not need to lower the indoor temperature. In such cases, the air conditioner needs to reduce indoor humidity while maintaining a relatively stable indoor temperature. In this situation, the air conditioner can operate in dual temperature and humidity control mode, adjusting both temperatures in tandem. This not only achieves good dehumidification but also keeps the indoor temperature near a preset threshold.

[0067] Optionally, after the air conditioner enters the temperature and humidity control mode, the indoor fan speed 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 needs 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 an air conditioner compressor is typically [10Hz, 130Hz], and the indoor fan speed range is typically [300r / min, 1200r / min]. Therefore, the operating frequency range of the air conditioner compressor can be correlated with the indoor fan speed range, 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 should be adjusted to 400r / min; when the compressor operating frequency is between 40Hz and 45Hz, the indoor fan speed should be adjusted to 500r / min; when the compressor operating frequency is between 45Hz and 50Hz, the indoor fan speed should be adjusted to 600r / min; when the compressor operating frequency is between 50Hz and 55Hz, the indoor fan speed should be adjusted to 700r / min; when the compressor operating frequency is between 55Hz and 60Hz, the indoor fan speed should be adjusted to 800r / min; and when the compressor operating frequency is above 60Hz, the indoor fan speed should be 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 the first time threshold, the indoor fan speed remains unchanged, and the fan speed is readjusted according to the compressor operating frequency after the first time threshold is reached.

[0071] Optionally, the first time threshold t1' can be set to [2 min, 3 min]. More specifically, t1' = 2 min, 2.5 min, or 3 min.

[0072] To reduce the occurrence of multiple changes in indoor fan speed within a short period of time due to fluctuations in compressor operating frequency, a first time threshold can be set. After the indoor fan speed changes, the current speed is maintained at the first time threshold until 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, the air conditioner is turned off if Tr < Ts-z, and turned on if Tr > Ts-z.

[0074] After the air conditioner enters dehumidification mode, the indoor temperature will gradually decrease as the dehumidification mode runs. If the temperature is too low, you can turn off the air conditioner in time to reduce the occurrence of excessively low temperatures.

[0075] Optionally, the value of z can range from [2℃, 4℃]. More specifically, z = 2℃, 3℃, or 4℃.

[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 regulate the indoor ambient temperature.

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

[0079] Where c is the third threshold; ω1 is the first corrected rotation speed; Tp is the indoor coil temperature; and T1 is the second temperature threshold.

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

[0081] Optionally, the value of c can range from [0.5℃, 1.5℃]. More specifically, c = 0.5℃, 1℃, or 1.5℃.

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

[0083] Optionally, the value of T1 can be in the range of [11℃, 13℃]. More specifically, T1 = 11℃, 12℃, or 13℃.

[0084] Optionally, the first preset duration t1 can be in the range of [1 min, 2 min]. More specifically, t1 = 1 min, 1.5 min, or 2 min.

[0085] Optionally, the indoor fan speed can be adjusted, and the range of compressor operating frequency can be adjusted, including adjusting the maximum operating frequency of the compressor and the indoor fan speed according to the indoor ambient temperature and indoor ambient humidity.

[0086] In dehumidification mode, the indoor humidity will gradually decrease, sometimes even falling far below the preset humidity level. In this case, it's necessary to adjust the compressor's maximum operating frequency and the indoor fan speed to reduce the problem of excessively dry indoor air.

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

[0088] Where 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] When Tr > Ts + d, it indicates that the indoor ambient temperature is relatively high, and the air conditioner can operate normally in dehumidification mode to reduce the indoor humidity and temperature. When Tr ≤ Ts + d, if 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 maintained near the set humidity.

[0090] Optionally, the value of d can be in the range of [4℃, 5℃]. More specifically, d = 4℃, 4.5℃, or 5℃.

[0091] Optionally, Rhs can take values ​​ranging from [45%, 55%]. More specifically, Rhs = 47%, 50%, or 52%.

[0092] Optionally, x can take values ​​ranging from [5%, 8%]. More specifically, x = 5%, 6%, or 7%.

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

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

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

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

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

[0098] Optionally, the second preset duration t2 can be in the range of [1 min, 2 min]. More specifically, t1 = 1 min, 1.5 min, or 2 min.

[0099] Optionally, the range of compressor operating frequency can be adjusted, including adjusting the minimum operating frequency of the compressor based on indoor humidity or outdoor temperature.

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

[0101] Wherein, 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 indoor humidity or outdoor temperature is low, the dehumidification effect of the air conditioner can be adjusted by changing the compressor's minimum frequency, further maintaining the indoor humidity near the set level. Furthermore, if the outdoor temperature range changes, the compressor's minimum operating frequency must remain at a second time threshold before any change to the minimum operating frequency. When the air conditioner is turned off and then on again, the compressor's initial frequency is fixed at F3.

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

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

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

[0106] Optionally, the value of T3 can be in the range of [30℃, 34℃]. More specifically, T3 = 31℃, 32℃, or 33℃.

[0107] Optionally, the value of T2 can be in the range of [24℃, 26℃]. More specifically, T2 = 24℃, 25℃, or 26℃.

[0108] Optionally, the value of T4 can be in the range of [18℃, 22℃]. More specifically, T4 = 19℃, 20℃, or 21℃.

[0109] Optionally, the third preset duration t3 can be in the range of [2 min, 4 min]. More specifically, t1 = 2 min, 3 min, or 4 min.

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

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

[0112] Combination Figure 3 As shown in the embodiments of this disclosure, another method for dehumidifying an air conditioner is provided, including:

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

[0114] S102, the processor obtains the indoor ambient temperature.

[0115] S103, the processor determines the range of indoor fan speed and compressor operating frequency based on the indoor ambient temperature and a first temperature threshold.

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

[0117] By setting a first temperature threshold, the real-time indoor temperature can be compared with the first temperature threshold, and the appropriate indoor fan speed and compressor frequency can be adjusted to keep the indoor temperature near the first temperature threshold, reducing the drop in indoor temperature caused by running the cooling mode.

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

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

[0120] Optionally, the value of M can be in the range of [-3℃, 1℃]. More specifically, M = -2℃, -1℃, 0.

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

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

[0123] Where 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; and b > e.

[0124] Combination Figure 4 As shown in the embodiments of this disclosure, another method for dehumidifying an air conditioner is provided, including:

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

[0126] S202, the processor obtains the indoor ambient temperature.

[0127] S203, the processor determines the range of indoor fan speed and compressor operating frequency based on the indoor ambient temperature and a first temperature threshold.

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

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

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

[0131] When the air conditioner is in dehumidification mode, the indoor temperature will continuously decrease due to heat exchange between the indoor air and the air conditioner's heat exchanger. If the user does not need to cool down at this time, the indoor temperature can be increased by using electric heating. Furthermore, when turning the electric heating on and off, it is also necessary to wait until the electric heating has been on for a third time threshold before turning it off; or wait until the electric heating has been off for a fourth time threshold before turning it on.

[0132] Optionally, the value of e can range from [1℃, 1.5℃]. More specifically, a = 1℃, 1.2℃, or 1.4℃.
