[0028] Figure 1 This is a schematic flowchart illustrating a method for adjusting the frequency of an air conditioner compressor according to an embodiment of the present invention. Figure 1 As shown, the method includes steps S110-S140.
[0029] S110. If the air conditioner is in cooling / heating mode, it will periodically check whether the ambient temperature has reached the set temperature.
[0030] In this embodiment, if the air conditioner is in cooling / heating mode, it periodically checks whether the ambient temperature has reached the set temperature, which is the user's desired temperature.
[0031] This 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 is controlled to increase its frequency to ensure the temperature control effect of the air conditioner. When the ambient temperature reaches the set temperature, the compressor is controlled to decrease its frequency so that the compressor can operate stably at a specific low frequency. This reduces energy consumption, lowers operating costs, and improves the 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 has reached the set temperature, the method further includes:
[0033] If the ambient temperature reaches the set temperature, the compressor will be controlled to reduce its frequency according to the preset compressor frequency control strategy.
[0034] In this embodiment, if the ambient temperature reaches the set temperature, the compressor is controlled to reduce its frequency according to a preset compressor frequency control strategy to reduce energy consumption and lower operating costs.
[0035] The step of controlling the compressor to reduce its frequency according to a preset compressor frequency control strategy includes:
[0036] The operating frequency corresponding to the current time period is determined based on the set temperature.
[0037] The set operating frequency and the initial operating frequency are input into the preset actual rate calculation formula η′= (P′-P0) / P0 to obtain the corresponding actual rate; wherein, the initial operating frequency is the termination frequency of the previous time period, η′ is the actual rate, P0 is the initial operating frequency, and P′ is the set operating frequency.
[0038] The target rate range corresponding to the actual operating frequency is obtained according to the frequency-range relationship table in the preset compressor frequency control strategy. If the actual rate is within the target rate range, the second rate corresponding to the target rate 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 rate is greater than the maximum value in the target rate range, the first rate 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 rate is less than the minimum value in the target rate range, the third rate 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 embodiments of the present invention can flexibly adjust the compressor frequency according to the compressor frequency control strategy, which can reduce unnecessary energy consumption and lower operating costs.
[0040] S120. If the set temperature is not reached, the operating set frequency corresponding to the current time period is determined 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 continuously adjusted and optimized through experiments or simulations.
[0042] S130. Input the set operating frequency and the initial operating frequency into the preset frequency ramping rate calculation formula to obtain the corresponding actual frequency ramping rate; wherein, the initial operating frequency is the termination frequency of the previous time period.
[0043] In this embodiment, the set operating frequency and the initial operating frequency are input into a preset frequency ramp-up rate calculation formula to obtain the corresponding actual frequency ramp-up rate. The initial operating frequency is the termination frequency of the previous time period, and the termination 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 consistent and can be set according to the actual application. This embodiment of the invention can precisely adjust the compressor's operating frequency based on the initial operating frequency of each time period, ensuring that the air conditioner maintains a stable operating state under any circumstances. This guarantees the air conditioner's temperature control effect while reducing energy consumption, lowering operating costs, and improving the user experience.
[0044] The formula for calculating the frequency ramp rate is η = (P′-P0) / P0; where η is the actual frequency ramp rate, P0 is the initial operating frequency, and P′ is the set operating frequency.
[0045] S140. Determine the corresponding target frequency increase rate according to the 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 actual frequency ramp rate is set with a corresponding target frequency ramp rate. 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 ramp rate is within the target rate range, the second rate corresponding to the target rate range is used as the target frequency ramp rate. If the actual frequency ramp rate is greater than the maximum value in the target rate range, the first rate is used as the target frequency ramp rate. If the actual frequency ramp rate is less than the minimum value in the target rate range, the third rate is used as the target frequency ramp rate.
[0047] The embodiments of the present invention can determine the corresponding target frequency ramp rate according to the preset compressor frequency control strategy and the actual frequency ramp rate, so as to flexibly adjust the compressor frequency, ensure that the air conditioner can maintain a stable operating state under any circumstances, guarantee the temperature control effect of the air conditioner, reduce energy consumption, reduce operating costs, and improve the user experience.
[0048] Existing inverter air conditioners typically adjust the compressor frequency based on ambient temperature. However, the embodiments of this invention do not rely heavily on ambient temperature. Instead, they flexibly adjust the compressor frequency based on the compressor's own frequency change rate. Therefore, compared to existing technologies, the air conditioner compressor frequency adjustment method proposed in this invention can better adapt to different environmental changes and achieve more efficient temperature control, enabling users to enjoy an ideal indoor environment in a shorter time.
[0049] In one embodiment, step S140 includes: obtaining the target rate range corresponding to the actual operating frequency according to the frequency-range relationship table in the compressor frequency control strategy;
[0050] Determine whether the actual upsampling rate is within the target rate range;
[0051] If the target rate is within the target rate range, then the second rate corresponding to the target rate range shall be taken as the target up-frequency rate.
[0052] In this embodiment, the target rate range corresponding to the actual operating frequency is obtained according to the frequency-range relationship table in the compressor frequency control strategy; wherein, the frequency-range relationship table can be continuously adjusted and optimized through experiments or simulations; it is determined whether the actual frequency ramp rate η is within the target rate range [μ2, μ1]; if it is within the target rate range, the second rate corresponding to the target rate range is taken as the target frequency ramp rate; wherein, each target rate range is pre-configured with a corresponding rate parameter, the rate parameter including a first rate, a second rate, and a third rate.
[0053] In one embodiment, after determining whether the actual upsampling rate is within the target rate range, the method further includes:
[0054] If it is not within the target rate range, then determine whether the actual upsampling rate is greater than a first threshold; wherein, the first threshold is the maximum value in the target rate range;
[0055] If it is greater than the first threshold, the first rate corresponding to the first threshold shall be taken as the target upsampling rate.
[0056] In this embodiment, if the actual upsampling rate is not within the target rate range, it is determined whether the actual upsampling rate is greater than a first threshold; wherein the first threshold is the maximum value in the target rate range; if it is greater, the first rate corresponding to the first threshold is taken as the target upsampling rate; wherein the first rate is greater than the second rate.
[0057] In one embodiment, after determining whether the actual upsampling rate is greater than the first threshold, the method further includes:
[0058] If it is not greater than, then the third rate will be used as the target upsampling rate.
[0059] In this embodiment, if the rate is not greater than the target rate, the third rate is taken as the target upsampling rate; wherein, the first rate > the second rate > the third rate.
[0060] In one embodiment, after controlling the compressor to increase its frequency 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 will be 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 precisely adjust the operating frequency of the compressor, ensuring that the air conditioner can maintain a stable operating state under any circumstances, guaranteeing the temperature control effect of the air conditioner, reducing energy consumption, lowering operating costs, and improving the user experience.
[0063] In one embodiment, after controlling the compressor to increase its frequency according to the target frequency increase rate, the method further includes:
[0064] If a shutdown / power failure signal is detected, the maximum operating frequency during operation will be used as the initial operating frequency for the next power-on.
[0065] In this embodiment, if a power off / shutdown signal is detected, the maximum operating frequency during operation is used as the initial operating frequency for the next startup. This allows for precise adjustment of the compressor's operating frequency based on the initial operating frequency during the next startup, ensuring that the air conditioner maintains a stable operating state under any circumstances. This guarantees the air conditioner's temperature control effect while reducing energy consumption, lowering operating costs, and improving the user experience.
[0066] In summary, the embodiments of the present invention can determine the corresponding target frequency ramp rate according to the preset compressor frequency control strategy and the actual frequency ramp rate, so as to flexibly adjust the compressor frequency, ensure that the air conditioner can maintain a stable operating state under any circumstances, guarantee the temperature control effect of the air conditioner, reduce energy consumption, reduce operating costs, and improve the user experience.
