[0028] Figure 1 The flowchart of the method for adjusting the frequency of the air conditioner compressor provided by the embodiment of the present invention is as follows. Figure 1 As shown, the method includes steps S110-S140.

[0029] S110: If the operation mode of the air conditioner is the cooling / heating mode, it is determined at regular intervals whether the ambient temperature reaches the set temperature.

[0030] In this embodiment, if the operation mode of the air conditioner is the cooling / heating mode, it is periodically determined whether the ambient temperature reaches the set temperature, where the set temperature is the desired temperature set by the user.

[0031] The embodiment of the present invention can dynamically adjust the operating frequency of the compressor based on the ambient temperature and the set temperature. When the ambient temperature does not reach the set temperature, the compressor will be controlled to increase the frequency to ensure the temperature control effect of the air conditioner; when the ambient temperature reaches the set temperature, the compressor will be controlled to reduce the frequency so that the compressor can operate stably at a specific low frequency, thereby reducing energy consumption, reducing operating costs and improving user experience while ensuring the temperature control effect of the air conditioner.

[0032] In one embodiment, after the timed determination of whether the ambient temperature reaches the set temperature, the method further includes:

[0033] If the ambient temperature reaches the set temperature, the compressor is controlled to reduce the frequency according to a preset compressor frequency control strategy.

[0034] In this embodiment, if the ambient temperature reaches the set temperature, the compressor is controlled to reduce the frequency according to a preset compressor frequency control strategy to reduce energy consumption and reduce operating costs.

[0035] The step of controlling the compressor to reduce frequency according to a preset compressor frequency control strategy includes:

[0036] Determine the operating setting frequency corresponding to the current time period according to the setting temperature;

[0037] The operating setting frequency and the initial operating frequency are input into the preset actual rate calculation formula η′=(P0-P′) / P0 to obtain the corresponding actual rate; wherein the initial operating frequency is the end frequency of the previous time period, η′ is the actual rate, P0 is the initial operating frequency, and P′ is the operating setting frequency.

[0038] A target speed range corresponding to the actual operating frequency is obtained according to a frequency-range relationship table in a preset compressor frequency control strategy; if the actual speed is within the target speed range, a second speed corresponding to the target speed range is used as a target frequency reduction rate, and the compressor is controlled to reduce the frequency according to the target frequency reduction rate; if the actual speed is greater than a maximum value in the target speed range, a first speed corresponding to the target speed range is used as the target frequency reduction rate, and the compressor is controlled to reduce the frequency according to the target frequency reduction rate; if the actual speed is less than a minimum value in the target speed range, a third speed corresponding to the target speed range is used as the target frequency reduction rate, and the compressor is controlled to reduce the frequency according to the target frequency reduction rate.

[0039] The embodiment of the present invention can flexibly adjust the compressor frequency according to the compressor frequency control strategy. This strategy can reduce unnecessary energy consumption and lower operating costs.

[0040] S120: If the set temperature is not reached, determine the operation setting frequency corresponding to the current time period according to the set temperature.

[0041] In this embodiment, if the set temperature is not reached, the operating set frequency corresponding to the current time period is determined according to the set temperature; specifically, the operating set frequency corresponding to the set temperature can be obtained according to a preset set temperature-operating set frequency relationship table; wherein, the set temperature-operating set frequency relationship table can be obtained by continuous adjustment and optimization through experiments or simulations.

[0042] S130, inputting the operating setting frequency and the initial operating frequency into a preset frequency increase rate calculation formula to obtain a corresponding actual frequency increase rate; wherein the initial operating frequency is the end frequency of the previous time period.

[0043] In this embodiment, the operating set frequency and the initial operating frequency are input into a preset frequency increase rate calculation formula to obtain the corresponding actual frequency increase rate; wherein, the initial operating frequency is the end frequency of the previous time period, and the end frequency is the actual operating frequency of the compressor at the end time of the previous time period; the length of each time period is the same, and the length of the time period can be set according to the actual application. The embodiment of the present invention can accurately adjust the operating frequency of the compressor based on the initial operating frequency of each time period, ensuring that the air conditioner can maintain a stable operating state under any circumstances, while ensuring the temperature control effect of the air conditioner, reducing energy consumption, reducing operating costs, and improving user experience.

[0044] The frequency increase rate calculation formula is η=(P0-P') / P0; wherein η is the actual frequency increase rate, P0 is the initial operating frequency, and P' is the operating setting frequency.

[0045] S140: Determine a corresponding target frequency increase rate according to a preset compressor frequency control strategy and the actual frequency increase rate, and control the compressor to increase the frequency within the current time period according to the target frequency increase rate.

[0046] In this embodiment, each of the actual frequency increase rates is provided with a corresponding target frequency increase rate, and the target rate range corresponding to the actual operating frequency can be obtained according to the frequency-range relationship table in the preset compressor frequency control strategy; if the actual frequency increase rate is within the target rate range, the second rate corresponding to the target rate range is used as the target frequency increase rate; if the actual frequency increase rate is greater than the maximum value in the target rate range, the first rate corresponding to the target rate range is used as the target frequency increase rate; if the actual frequency increase rate is less than the minimum value in the target rate range, the third rate corresponding to the target rate range is used as the target frequency increase rate.

[0048] Existing variable frequency air conditioners usually adjust the compressor frequency based on the ambient temperature.

Therefore, compared with the prior art, the air conditioner compressor frequency adjustment method proposed in the present invention can better adapt to different environmental changes, achieve more efficient temperature control, and enable users to enjoy an ideal indoor environment in a shorter time.

[0049] In one embodiment, step S140 includes: obtaining a target speed range corresponding to the actual operating frequency according to a frequency-range relationship table in the compressor frequency control strategy;

[0053] In one embodiment, after determining whether the actual frequency increase rate is within the target rate range, the method further includes:

[0054] If it is not within the target rate range, determining whether the actual frequency increase rate is greater than a first threshold; wherein the first threshold is the maximum value in the target rate range;

[0060] In one embodiment, after controlling the compressor to perform frequency increase according to the target frequency increase rate, the method further includes:

[0061] If the current time reaches the end time of the current time period, the actual operating frequency of the current time is used as the initial operating frequency of the next time period.

[0062] In this embodiment, if the current time reaches the end time of the current time period, the actual operating frequency of the current time is used as the initial operating frequency of the next time period to accurately adjust the operating frequency of the compressor, ensuring that the air conditioner can maintain a stable operating state under any circumstances, while ensuring the temperature control effect of the air conditioner, reducing energy consumption, reducing operating costs, and improving user experience.

[0063] In one embodiment, after controlling the compressor to perform frequency increase according to the target frequency increase rate, the method further includes:

[0064] If a shutdown / power-off signal is detected, the maximum operating frequency during operation will be used as the initial operating frequency at the next startup.

[0065] In this embodiment, if a shutdown / power-off signal is detected, the maximum operating frequency during the operation process is used as the initial operating frequency when the power is turned on next time, so that the operating frequency of the compressor can be accurately adjusted according to the initial operating frequency when the power is turned on next time, ensuring that the air conditioner can maintain a stable operating state under any circumstances, ensuring the temperature control effect of the air conditioner, reducing energy consumption, reducing operating costs, and improving user experience.

[0066] To sum up, the embodiments of the present invention can determine the corresponding target frequency increase rate according to the preset compressor frequency control strategy and the actual frequency increase rate, so as to realize flexible adjustment of the compressor frequency, ensure that the air conditioner can maintain a stable operating state under any circumstances, ensure the temperature control effect of the air conditioner, reduce energy consumption, reduce operating costs, and improve user experience.
