Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air conditioner control, and particularly to an air conditioner power control method, device, storage medium and air conditioner. Background Art
[0002] In countries such as Africa, due to the unstable national power grid and insufficient power generation, power outages often occur in households. Therefore, many households will prepare fuel generators for use when the household power grid is out of power. However, the power supplied by the generator is often limited. Air conditioners are high-power electrical appliances. If used when the generator is supplying power, if the air conditioner power is too high, it is easy to cause a power outage or too low voltage, affecting the use of other household appliances. Existing air conditioners sold to Africa do not consider the usage situation when powered by a generator, and all try to make the air conditioner operate at its maximum level. The compressor frequency will run at the maximum frequency as much as possible to ensure sufficient cooling capacity. However, the power of the air conditioner is very large among household appliances. If the household is in the generator power supply mode, it is easy to cause frequent tripping and other situations in the household power grid.

[0047] Embodiments of the present invention provide an air conditioner power control method. Referring to Figure 2 , Figure 2 is a schematic flowchart of a first embodiment of an air conditioner power control method of the present invention.
[0048] In this embodiment, the air conditioner power control method includes the following steps:
[0049] Step S10: When the power supply mode of the air conditioner is in the generator power supply mode, obtain the current working current when the air conditioner is running.
[0050] It should be noted that the execution subject of this embodiment may be an air conditioner power control device. The air conditioner power control device may be an electronic device such as a personal computer, a server, or a vehicle-mounted terminal, or may also be other controllers and devices that can implement the same or similar functions. This embodiment does not limit this. In this embodiment and the following embodiments, the air conditioner power control method of the present invention will be described by taking the air conditioner power control device as an example.
[0051] In this embodiment, the air conditioner is usually powered by the national power grid during operation. However, in some countries or regions, such as those in Africa, due to the instability of the national power grid and insufficient power generation, power outages often occur in households. Therefore, many households will prepare fuel generators for use when the household power grid is out of power. The power generation modes of the air conditioner in this embodiment include the grid power supply mode and the generator power supply mode. When the national power grid generates electricity stably, the household power grid of each household supplies power to the air conditioner. At this time, the air conditioner is in the grid power supply mode. Although the air conditioner is a household appliance with a relatively large power, the grid power supply is sufficient, and there is no need to limit the power of the air conditioner, and it can be adjusted according to the actual indoor environmental temperature. For example, the compressor frequency can be adjusted according to the user-set temperature and the indoor environmental temperature. When the national power grid is unstable and the power generation is insufficient, the fuel generator needs to supply power to the air conditioner at this time. At this time, the air conditioner is in the generator power supply mode. In this mode, the power of the air conditioner needs to be limited. The refrigeration system diagram in the generator power supply mode is as shown in Figure 3 shown. In Figure 3 , 1 is the compressor, 2 is the four-way valve, 3 is the outdoor heat exchanger, 4 is the main throttling device (including capillary tube and throttle valve), 5 is the indoor heat exchanger, 6 is the air conditioner electronic control system (detecting current and voltage), 7 is the generator module, and the generator module supplies power to other household appliances and the air conditioner.
[0052] It can be understood that in this embodiment, the power of the air conditioner is limited by adjusting the compressor frequency. At the same time as adjusting the compressor frequency, it will affect the working current of the air conditioner. For example, increasing the compressor frequency will increase the working current of the air conditioner, and decreasing the compressor frequency will decrease the working current of the air conditioner. Therefore, it is necessary to detect the current working current. Specifically, this embodiment can detect the current working current according to the detection instruction input by the user. Further, a preset time can be set in this embodiment. When the preset time is reached, the current working current is automatically detected. In this embodiment, it can also be detected in other ways and can be set accordingly according to the actual situation. This embodiment does not limit this.
[0053] In specific implementation, in order to avoid affecting the use of the air conditioner and other household appliances, the fuel generator is detected in real time in this embodiment, that is, the operating state of the generator is detected, the operating state information of the generator is obtained, and according to the status identifier included in the operating state information, it is judged whether the generator is in the generator state at this time according to the status identifier. For example, the operating state corresponding to the status identifier 1 is the power generation state.
[0054] Step S20: Adjust the compressor frequency of the air conditioner according to the current working current so that the current working current is less than or equal to the preset safety current threshold.
[0055] In specific implementation, the air conditioner has a corresponding safety current under the generator power supply mode, that is, a preset safety current threshold. The preset safety current threshold is the maximum operating current value of the air conditioner under the generator power supply mode, and the preset safety current threshold can be set accordingly according to actual requirements. This embodiment does not limit this. And it can be understood that before adjusting the compressor frequency, it is necessary to compare the preset safety current threshold with the current working current. If the preset safety current threshold is greater than or equal to the current working current, there is no need to adjust the compressor frequency. If the preset safety current threshold is less than the current working current, it is necessary to adjust the compressor frequency so that the preset safety current threshold is greater than the current working current. In this embodiment, the compressor frequency is reduced to reduce the current working current of the air conditioner.
[0056] Step S30: When the current working current is less than or equal to the preset safety current threshold, obtain the current working voltage of the air conditioner.
[0057] It should be noted that after reducing the compressor frequency to reduce the current working current, this embodiment will further adjust the compressor frequency, and the adjustment basis is the working voltage. Specifically, this embodiment can detect the current working voltage according to the detection instruction input by the user. Further, a preset time can also be set in this embodiment, and when the preset time is reached, the current working voltage is automatically detected. In this embodiment, it can also be detected in other ways and can be set accordingly according to the actual situation. This embodiment does not limit this.
[0058] Step S40: Adjust the compressor frequency of the air conditioner according to the current working voltage to control the power of the air conditioner.
[0059] In specific implementation, the magnitude of the compressor frequency determines the magnitude of the power of the air conditioner. In this embodiment, the power is limited by adjusting the compressor frequency. Different working voltages of the air conditioner have different control strategies. In this embodiment, the control strategy corresponding to the current working voltage can be determined according to the correspondence between the working voltage and the control strategy, and then the compressor frequency of the air conditioner is adjusted according to the determined control strategy. The adjustment includes increasing the compressor frequency or decreasing the compressor frequency.
[0060] In this embodiment, when the power supply mode of the air conditioner is the generator power supply mode, the current working current during the operation of the air conditioner is obtained; the compressor frequency of the air conditioner is adjusted according to the current working current so that the current working current is less than or equal to a preset safety current threshold; when the current working current is less than or equal to the preset safety current threshold, the current working voltage of the air conditioner is obtained; the compressor frequency of the air conditioner is adjusted according to the current working voltage to control the power of the air conditioner. By adjusting the compressor frequency of the air conditioner, the working current of the air conditioner is limited, and then the compressor frequency of the air conditioner is further adjusted according to the working voltage of the air conditioner, which greatly limits the power of the air conditioner when powered by the generator.
[0061] Reference Figure 4 , Figure 4 is a schematic flowchart of the second embodiment of a method for controlling the power of an air conditioner according to the present invention.
[0062] Based on the above first embodiment, the step S40 in this embodiment specifically includes:
[0063] Step S401: Compare the current working voltage with the rated voltage to obtain the voltage range in which the current working voltage is located.
[0064] In a specific implementation, a corresponding control strategy can be determined according to the current working voltage. The control strategy is related to the corresponding voltage range of the current working. In this embodiment, the voltage range is obtained after comparing the current working voltage with the rated voltage. The rated voltage is divided into three ranges, the first voltage range, the second voltage range, and the third voltage range. Assuming the rated voltage is U0, the first voltage range can be set to 98%U0 to 100%U0, the second voltage range can be set to 90%U0 to 98%U0, and the third voltage range can be set to 0%U0 to 90%U0. The voltage range in this embodiment can also be adjusted according to the actual situation, and this embodiment does not limit this.
[0065] Step S402: Adjust the compressor frequency of the air conditioner according to the voltage range to control the power of the air conditioner.
[0066] It should be noted that there is a corresponding relationship between the voltage range and the control strategy. For example, the first voltage range corresponds to the first control strategy, the second voltage range corresponds to the second control strategy, the third voltage range corresponds to the third control strategy, etc. Then, the compressor frequency is adjusted according to the control strategy to achieve the control of the power of the air conditioner.
[0067] Furthermore, in this embodiment, the maximum voltage value and the minimum voltage value corresponding to different voltage ranges are different. For the three voltage ranges listed above, the maximum voltage value corresponding to the first voltage range is 100%U0, and the minimum voltage value is 98%U0. The same applies to the second voltage range and the third voltage range. Among them, 98% and 100% in the first voltage range are preset voltage coefficients, and the voltage coefficients can be set accordingly according to the actual situation. This embodiment does not limit this.
[0068] It should also be noted that the first preset voltage is the minimum voltage value corresponding to the first voltage range. According to the first preset voltage, it can be judged whether the current working voltage is within the first voltage range. For example, if the first voltage range can be set as 98%U0 - 100%U0, then the first preset voltage is 98%U0. If the current working voltage is within the first voltage range, it means that the generator supplies sufficient power at this time, and the air conditioner does not need to adjust the power and can operate normally according to the temperature set by the user, that is, adjust the compressor frequency normally. However, it should be emphasized that if the temperature set by the user is lower than the ambient temperature, the compressor frequency needs to be increased. But at this time, the air conditioner is still in the generator power supply mode. Therefore, when increasing the compressor frequency, it is necessary to ensure that the compressor frequency does not exceed the compressor frequency corresponding to the preset safety current threshold, so as to ensure that increasing the compressor frequency will not cause the working current to exceed the preset safety current threshold.
[0069] Furthermore, if it is detected that the current working voltage is within the second voltage range, it means that the generator is struggling to supply power at this time. If the compressor frequency is further increased, it will affect the normal use of other household appliances. To avoid this situation, even if the temperature set by the user is low, the compressor frequency will not be increased.
[0070] In this embodiment, by comparing the current working voltage with the second preset voltage and the first preset voltage, it is judged whether the current working voltage is within the second voltage range. The second preset voltage is the minimum voltage value corresponding to the second voltage range. For example, if the second voltage range can be set as 90%U0 - 98%U0, then the second preset voltage is 90%U0. If the current working voltage is greater than 90%U0, it means that the current working voltage is within the second voltage range. At this time, regardless of the temperature set by the user, the compressor frequency is not adjusted and remains unchanged.
[0071] Furthermore, when the current working voltage is within the second voltage range, if it is detected that the current working voltage continues to drop, it indicates that the power supply capacity of the generator is gradually weakening. At this time, if the compressor frequency remains unchanged, it will also affect the normal use of other household appliances. To avoid this situation, when the current working voltage drops, the compressor frequency will be adjusted. In this embodiment, the compressor frequency is adjusted to decrease the compressor frequency.
[0072] In a specific implementation, there is a corresponding relationship between the reduction amount of the compressor frequency and the drop amplitude of the current working voltage. The drop amplitude is determined by the voltage difference between the current working voltages at different times before and after. For example, the current working voltage at time T1 is U1, and the current working voltage at time T2 is U2. If the current working voltage U1 > U2, then the voltage drop amplitude can be obtained as U1 - U2. According to the corresponding relationship, the target frequency adjustment amount can be obtained. For example, the target frequency adjustment amount corresponding to the voltage drop amplitude ΔU is Δf. In this embodiment, the corresponding relationship is not restricted and can be set accordingly according to actual adjustment requirements. This embodiment does not restrict this. Specifically, in this implementation, in order to make the reduction of the compressor frequency more accurate, the target frequency adjustment amount can be determined through a frequency adjustment coefficient. Suppose the voltage drop amplitude is DU1, and the corresponding frequency adjustment coefficient is n1, then the target frequency adjustment amount is n1f. Suppose the voltage drop amplitude is DU2, and the corresponding frequency adjustment coefficient is n2, then the target frequency adjustment amount is n2f, where f is the preset compressor frequency adjustment reference and can be set accordingly according to the actual situation. This embodiment does not restrict this.
[0073] Furthermore, if it is detected that the current working voltage is within the third voltage range, it indicates that the power supply of the generator is insufficient at this time. In order not to affect the use of other electrical appliances, the compressor frequency needs to be reduced at this time. Since reducing the compressor frequency will increase the working voltage, during the process of reducing the compressor frequency, the working voltage is detected in real time. When it is detected that the working voltage has increased to within the second voltage range, the reduction of the compressor frequency is stopped, and the frequency of the compressor at this time is kept unchanged.
[0074] In this embodiment, by comparing the current working voltage with the second preset voltage, it is determined whether the current working voltage is within the third voltage range. The second preset voltage is also the maximum voltage value corresponding to the third voltage range. For example, the third voltage range can be set as 0%U0 to 90%U0, then the second preset voltage is 90%U0. If the current working voltage is less than 90%U0, it indicates that the current working voltage is within the third voltage range, and it can be determined that the power supply of the generator is insufficient.
[0075] It is easy to understand that the compressor frequency cannot be reduced infinitely. The compressor frequency has a minimum frequency. During the process of reducing the compressor frequency, it is detected in real time whether the minimum frequency is reached. If the minimum frequency is reached, it is detected whether the working voltage at this time is within the second voltage range. If the working voltage is still not within the second voltage range, it indicates that the power supply of the generator is seriously insufficient, and even running the compressor at the minimum frequency cannot increase the working voltage of the air conditioner. At this time, only the compressor of the air conditioner can be turned off to avoid affecting the normal operation of other household appliances.
[0076] In this embodiment, by comparing the current operating voltage with the rated voltage, the voltage range in which the current operating voltage is located is obtained, and the compressor frequency of the air conditioner is adjusted according to the voltage range to control the power of the air conditioner. Different control strategies are determined according to different voltage ranges corresponding to the current operating voltage, and then the power of the air conditioner is limited according to different control strategies, which can effectively ensure that the air conditioner does not affect the normal operation of other household appliances.
[0077] In addition, an embodiment of the present invention further provides a storage medium, on which an air conditioner power control program is stored. When the air conditioner power control program is executed by a processor, the steps of the air conditioner power control method as described above are implemented.
[0078] Refer to Figure 5 , Figure 5 which is a structural block diagram of the first embodiment of the air conditioner power control device of the present invention.
[0079] As Figure 5 shown, the air conditioner power control device proposed by the embodiment of the present invention includes:
[0080] An acquisition module 10, configured to acquire the current operating current when the air conditioner is running when the power supply mode of the air conditioner is in the generator power supply mode.
[0081] In this embodiment, the air conditioner is usually powered by the national power grid during operation. However, in some countries or regions, such as African regions, due to the instability of the national power grid and insufficient power generation, power outages often occur in families. Therefore, many families will prepare fuel generators for use when the household power grid is out of power. The power generation modes of the air conditioner in this embodiment include the grid power supply mode and the generator power supply mode. When the national power grid generates power stably, the household power grid of each family supplies power to the air conditioner. At this time, the air conditioner is in the grid power supply mode. Although the air conditioner is a household appliance with a relatively large power, the grid power supply is sufficient, and there is no need to limit the power of the air conditioner, and it can be adjusted according to the actual indoor environmental temperature. For example, the compressor frequency is adjusted according to the user-set temperature and the indoor environmental temperature. When the national power grid is unstable and the power generation is insufficient, the air conditioner needs to be powered by a fuel generator at this time. At this time, the air conditioner is in the generator power supply mode. In this mode, the power of the air conditioner needs to be limited. The refrigeration system diagram in the generator power supply mode is as Figure 3 shown. In Figure 3 , 1 is a compressor, 2 is a four-way valve, 3 is an outdoor heat exchanger, 4 is a main throttling device (including capillary tube, throttle valve), 5 is an indoor heat exchanger, 6 is an air conditioner electronic control system (detecting current and voltage), 7 is a generator module, and the generator module supplies power to other household appliances and the air conditioner.
[0082] It can be understood that in this embodiment, the power of the air conditioner is limited by adjusting the compressor frequency. When adjusting the compressor frequency, the working current of the air conditioner will be affected. For example, increasing the compressor frequency will increase the working current of the air conditioner, and decreasing the compressor frequency will decrease the working current of the air conditioner. Therefore, it is necessary to detect the current working current. Specifically, in this embodiment, the current working current can be detected according to the detection instruction input by the user. Further, a preset time can be set in this embodiment, and when the preset time is reached, the current working current is automatically detected. In this embodiment, detection can also be performed in other ways and can be set accordingly according to the actual situation. This embodiment does not limit this.
[0083] In specific implementation, in order to avoid affecting the use of the air conditioner and other household appliances, in this embodiment, the fuel generator is detected in real time, that is, the operating state of the generator is detected, the operating state information of the generator is obtained, and according to the status identifier included in the operating state information, it is judged whether the generator is in the generator state at this time. For example, the operating state corresponding to status identifier 1 is the power generation state.
[0084] The adjustment module 20 is used to adjust the compressor frequency of the air conditioner according to the current working current so that the current working current is less than or equal to the preset safe current threshold.
[0085] In specific implementation, the air conditioner has a corresponding safe current in the generator power supply mode, that is, the preset safe current threshold. The preset safe current threshold is the maximum operating current value of the air conditioner in the generator power supply mode. The preset safe current threshold can be set accordingly according to actual needs. This embodiment does not limit this. And it can be understood that before adjusting the compressor frequency, it is necessary to compare the preset safe current threshold with the current working current. If the preset safe current threshold is greater than or equal to the current working current, the compressor frequency does not need to be adjusted. If the preset safe current threshold is less than the current working current, the compressor frequency needs to be adjusted so that the preset safe current threshold is greater than the current working current. In this embodiment, the compressor frequency is reduced to reduce the current working current of the air conditioner.
[0086] The acquisition module 10 is further used to acquire the current working voltage of the air conditioner when the current working current is less than or equal to the preset safe current threshold.
[0087] The adjustment module 20 is further used to adjust the compressor frequency of the air conditioner according to the current working voltage to control the power of the air conditioner.
[0088] In this embodiment, when the power supply mode of the air conditioner is in the generator power supply mode, the current working current during the operation of the air conditioner is obtained; the compressor frequency of the air conditioner is adjusted according to the current working current so that the current working current is less than or equal to a preset safe current threshold; when the current working current is less than or equal to the preset safe current threshold, the current working voltage of the air conditioner is obtained; the compressor frequency of the air conditioner is adjusted according to the current working voltage to control the power of the air conditioner. By adjusting the compressor frequency of the air conditioner, the working current of the air conditioner is limited, and then the compressor frequency of the air conditioner is further adjusted according to the working voltage of the air conditioner, greatly limiting the power of the air conditioner when powered by the generator.
[0089] It should be understood that the above is only an example and does not constitute any limitation to the technical solution of the present invention. In specific applications, those skilled in the art can set according to needs, and the present invention does not limit this.
[0090] It should be noted that the above-described working process is only illustrative and does not limit the protection scope of the present invention.
