Obviously, the drawings in the following description are some embodiments of the present application. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

Detailed Embodiments

[0023] To make the objectives, technical solutions and advantages of this application clearer, the following will clearly and completely describe the technical solutions in this application with reference to the accompanying drawings in this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.

[0024] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0025] The following will describe in detail the operating principle of the air conditioner involved in the embodiments of this application: As Figure 1 shown, the compressor compresses the refrigerant (refrigerant medium), and transports it to the condenser through a pipeline. The high-temperature and high-pressure gaseous refrigerant releases heat in the condenser and becomes a medium-temperature and high-pressure liquid refrigerant. After that, the medium-temperature and high-pressure liquid refrigerant becomes a low-temperature and low-pressure liquid refrigerant after being depressurized by a capillary tube (throttling unit). The low-temperature and low-pressure liquid refrigerant is transported to the evaporator and evaporates from a liquid into a gas, and absorbs a large amount of heat during the evaporation process. Finally, the low-temperature and low-pressure gaseous refrigerant in the evaporator is transported to the compressor to participate in the next cycle. When the air conditioner is cooling, the heat exchanger of the outdoor unit is the condenser, and the heat exchanger of the indoor unit is the evaporator; conversely, when the air conditioner is heating, the heat exchanger of the outdoor unit is the evaporator, and the heat exchanger of the indoor unit is the condenser.

[0026] In view of the above technical problems existing in the related art, the embodiments of this application provide an air conditioner power supply control method based on hybrid power supply. The air conditioner to which this method is applied is powered by a hybrid power supply method that combines wind power supply, solar power supply, and mains power supply. By adjusting the power supply ratio of various power supply methods, the ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner is within a preset ratio range, so that the air conditioner can stabilize the power supply within the range of the operating required voltage through a switching regulator.

[0027] The following will combine with the accompanying drawings to provide a detailed description of the air conditioner power supply control method based on hybrid power supply provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0028] As Figure 1 shown, an air conditioner power supply control method based on hybrid power supply provided by an embodiment of the present application may include the following steps 101 and 102: Step 101, during the operation of the air conditioner, calculate the reference ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner.

[0029] Exemplarily, when the total power supply capacity provided by the hybrid power supply method is within the range of 80% to 120% of the total power supply demand of the air conditioner (i.e., the above preset ratio range), the voltage can be stabilized within the operating demand voltage range of the air conditioner through a switching regulator. In the embodiments of the present application, power, voltage, or current, etc. can be used to characterize the power supply capacity or power supply demand.

[0030] It should be noted that the switching regulator uses an output stage to repeatedly switch between the "on" and "off" states, and together with energy storage components (capacitors and inductors), generates an output voltage. Its adjustment is achieved by adjusting the switching timing according to the feedback samples of the output voltage.

[0031] Step 102, if the reference ratio is within the preset ratio range, keep the current power supply method unchanged; otherwise, based on the change trends of the power supply methods in the hybrid power supply method at the current moment, adjust the proportion of each power supply method in the hybrid power supply method so that the ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner at the next moment remains within the preset ratio range.

[0032] Wherein, when the ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner is within the preset ratio range, the air conditioner stabilizes the power supply within the operating demand voltage range through a switching regulator.

[0033] It can be understood that the wind force usually changes from small to large or from large to small, and the same is true for the light radiation intensity. There is a changing process. Therefore, for power supply, the wind power supply and solar power supply will also have a changing trend. By using such a changing trend, the power supply capacity at the next moment can be predicted.

[0034] Specifically, in the above step 102, the step of adjusting the proportion of each power supply method in the hybrid power supply method based on the change trends of the power supply methods in the hybrid power supply method at the current moment may include the following steps 102a, 102b, and 102c: Step 102a: Obtain the first change trend of wind power supply and the second change trend of solar power supply in the hybrid power supply mode within a preset time period.

[0035] Step 102b: Based on the first change trend, determine the first power supply capacity of the wind power supply at the next moment, and based on the second change trend, determine the second power supply capacity of the solar power supply at the next moment.

[0036] Step 102c: Adjust based on the hybrid power supply strategy, the first power supply capacity, the second power supply capacity, and the mains power supply capacity to obtain a hybrid power supply mode in which the total power supply capacity meets the total power supply demand.

[0037] Among them, the proportions of each power supply mode in different hybrid power supply strategies are different.

[0038] Exemplarily, after determining the change trends of wind power supply and solar power supply, the power supply capacities of wind power supply and solar power supply at the next moment can be predicted, and then the proportions of different power supply modes can be adjusted according to different power supply strategies.

[0039] It should be noted that since the mains power is relatively stable, it can be defaulted that the power supply capacities at the current moment and the next moment can both meet the power consumption requirements of the air conditioner.

[0040] Exemplarily, the user can select different power supply strategies according to the scenario requirements. For example, a stable power supply strategy with mains power supply as the main part and an energy-saving power supply strategy with new energy power supply as the main part. The proportions of various power supply modes in different power supply strategies are different.

[0041] Specifically, in the above step 102c, the step of adjusting based on the hybrid power supply strategy, the first power supply capacity, the second power supply capacity, and the mains power supply capacity to obtain a hybrid power supply mode in which the total power supply capacity meets the total power supply demand may further include the following step 102c1 or step 102c2: Step 102c1: When the hybrid power supply strategy is a stable priority power supply strategy, adjust the power supply ratio of the mains power supply according to the maximum proportion of wind power supply and the maximum proportion of solar power supply indicated by the stable priority power supply strategy.

[0042] Step 102c2: When the hybrid power supply strategy is an energy-saving priority power supply strategy, adjust the power supply ratios of wind power supply and solar power supply according to the maximum proportion of mains power supply indicated by the energy-saving priority power supply strategy.

[0043] Exemplarily, since different power supply strategies limit the maximum proportion of each power supply capacity, there is still a situation where the power supply capacity is insufficient. For example, when the proportion of mains power supply reaches the maximum value, but due to the insufficient power supply capacity of wind power supply and solar power supply, at this time, it is necessary to increase the proportion of mains power supply to meet the power consumption demand of the air conditioner.

[0044] Specifically, the above step 102c2 may further include the following step 102c21: Step 102c21: When the hybrid power supply strategy is the energy-saving priority power supply strategy, if after adjusting the mains power supply to the maximum proportion, the ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner is less than the minimum value of the preset proportion range, then increase the maximum proportion of the mains power supply until the ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner at the next moment remains within the preset proportion range.

[0045] It should be noted that for the air conditioner power supply control method based on hybrid power supply in the embodiments of the present application, it is only necessary to keep the total power supply capacity of the hybrid power supply within the preset proportion range of the total power supply demand of the air conditioner. Since the wind power supply and solar power supply will fluctuate, during hybrid power supply, the output of the mains power supply can be dynamically adjusted to achieve stable power supply.

[0046] It should be noted that the solar power supply in the embodiments of the present application refers to the electric energy generated by using solar energy, which can directly supply power to the solar photovoltaic power generation panel, or the storage battery that stores the electric energy generated by the photovoltaic power generation panel, or can also supply power to both the photovoltaic power generation panel and the storage battery at the same time. Similarly, the wind power supply refers to the electric energy generated by using wind energy, which can directly supply power to the wind turbine, or the storage battery that stores the electric energy generated by the wind turbine, or can also supply power to both the wind turbine and the storage battery at the same time.

[0047] The air conditioner power supply control method based on hybrid power supply provided by the embodiments of the present application first calculates the reference ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner during the operation of the air conditioner; then, if the reference ratio is within the preset proportion range, the current power supply method remains unchanged, otherwise, based on the change trend of each power supply method in the hybrid power supply method at the current moment, the proportion of each power supply method in the hybrid power supply method is adjusted so that the ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner at the next moment remains within the preset proportion range. In this way, by adjusting the power supply proportion of various power supply methods, the ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner is within the preset proportion range, enabling the air conditioner to stabilize the power supply within the range of the operating required voltage through a switching regulator.

[0048] It should be noted that for the air conditioner power supply control method based on hybrid power supply provided in the embodiments of the present application, the execution subject may be an air conditioner power supply control device based on hybrid power supply, or a control module in the air conditioner power supply control device based on hybrid power supply for executing the air conditioner power supply control method based on hybrid power supply. In the embodiments of the present application, taking the air conditioner power supply control device based on hybrid power supply as an example to execute the air conditioner power supply control method based on hybrid power supply, the air conditioner power supply control device based on hybrid power supply provided in the embodiments of the present application is described.

[0049] It should be noted that in the embodiments of the present application, the air conditioner power supply control method based on hybrid power supply shown in each of the above method drawings is exemplarily described by taking one drawing in the embodiments of the present application as an example. Specifically, when implemented, the air conditioner power supply control method based on hybrid power supply shown in each of the above method drawings can also be implemented in combination with any other combinable drawings schemed in the above embodiments, which will not be elaborated here.

[0050] The air conditioner power supply control device based on hybrid power supply provided by the present application is described below, and the following description can be correspondingly referred to the air conditioner power supply control method based on hybrid power supply described above.

[0051] Figure 2 It is a schematic structural diagram of an air conditioner power supply control device based on hybrid power supply provided in an embodiment of the present application, as Figure 2 shown, and specifically includes: A calculation module 201, configured to calculate a reference ratio of the total power supply capacity provided by the hybrid power supply mode to the total power supply demand of the air conditioner during the operation of the air conditioner; a control module 202, configured to, if the reference ratio is within a preset ratio range, keep the current power supply mode unchanged, otherwise, based on the change trend of each power supply mode in the hybrid power supply mode at the current moment, adjust the proportion of each power supply mode in the hybrid power supply mode so that the ratio of the total power supply capacity provided by the hybrid power supply mode to the total power supply demand of the air conditioner at the next moment is kept within the preset ratio range; wherein, when the ratio of the total power supply capacity provided by the hybrid power supply mode to the total power supply demand of the air conditioner is within the preset ratio range, the air conditioner stabilizes the power supply within the range of the operating demand voltage through a switching regulator.

[0052] Optionally, the control module 202 is specifically configured to obtain a first change trend of wind power supply and a second change trend of solar power supply within a preset duration in the hybrid power supply mode; the control module 202 is further specifically configured to determine a first power supply capacity of the wind power supply at the next moment based on the first change trend, and determine a second power supply capacity of the solar power supply at the next moment based on the second change trend; the control module 202 is further specifically configured to perform adjustment based on a hybrid power supply strategy, the first power supply capacity, the second power supply capacity, and the mains power supply capacity to obtain a hybrid power supply mode in which the total power supply capacity meets the total power supply demand; wherein, the proportions of each power supply mode in different hybrid power supply strategies are different.

[0053] Optionally, when the hybrid power supply strategy is a stable priority power supply strategy, the control module 202 is specifically configured to adjust the power supply ratio of the mains power supply according to the maximum proportion of the wind power supply and the maximum proportion of the solar power supply indicated by the stable priority power supply strategy.

[0054] Optionally, when the hybrid power supply strategy is an energy-saving priority power supply strategy, the control module 202 is specifically configured to adjust the power supply ratios of the wind power supply and the solar power supply according to the maximum proportion of the mains power supply indicated by the energy-saving priority power supply strategy.

[0055] Optionally, when the hybrid power supply strategy is an energy-saving priority power supply strategy, if the ratio of the total power supply capacity provided by the hybrid power supply mode to the total power supply demand of the air conditioner is less than the minimum value of the preset ratio range after adjusting the mains power supply to the maximum proportion, the maximum proportion of the mains power supply is increased until the ratio of the total power supply capacity provided by the hybrid power supply mode to the total power supply demand of the air conditioner at the next moment remains within the preset ratio range.

[0056] The air conditioner power supply control device based on hybrid power supply provided by this application first calculates a reference ratio of the total power supply capacity provided by the hybrid power supply mode to the total power supply demand of the air conditioner during the operation of the air conditioner; then, if the reference ratio is within the preset ratio range, the current power supply mode remains unchanged, otherwise, based on the change trends of each power supply mode in the hybrid power supply mode at the current moment, the proportions of each power supply mode in the hybrid power supply mode are adjusted so that the ratio of the total power supply capacity provided by the hybrid power supply mode to the total power supply demand of the air conditioner at the next moment remains within the preset ratio range. In this way, by adjusting the power supply proportions of various power supply modes, the ratio of the total power supply capacity provided by the hybrid power supply mode to the total power supply demand of the air conditioner is within the preset ratio range, enabling the air conditioner to stabilize the power supply within the range of the operating required voltage through a switching regulator.

The method includes: First, during the operation of the air conditioner, calculate the reference ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner; then, if the reference ratio is within the preset ratio range, keep the current power supply method unchanged, otherwise, based on the change trend of each power supply method in the hybrid power supply method at the current moment, adjust the proportion of each power supply method in the hybrid power supply method so that the ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner at the next moment remains within the preset ratio range. In this way, by adjusting the power supply proportion of various power supply methods, the ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner is within the preset ratio range, so that the air conditioner can stabilize the power supply within the range of the operating required voltage through a switching regulator.

[0058] In addition, when the logical instructions in the above-mentioned memory 330 can be implemented in the form of software functional units and sold or used as an independent product, they can be stored in a computer-readable storage medium.

In this way, by adjusting the power supply proportion of various power supply methods, the ratio of the total power supply capacity provided by the hybrid power supply method to the total power supply demand of the air conditioner is within the preset proportion range, so that the air conditioner can stabilize the power supply within the range of the operating demand voltage through a switching regulator.
