Detailed Description of the Embodiments

[0024] To make the objectives, technical solutions, and advantages of the present application clearer, the following will clearly and completely describe the technical solutions in the present application with reference to the drawings in the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0025] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0026] The following will provide a detailed description of the operating principle of the air conditioner involved in the embodiments of the present application: The compressor compresses the refrigerant, transports it through a pipeline to the condenser. The high-temperature and high-pressure gaseous refrigerant releases heat in the condenser and becomes a medium-temperature and high-pressure liquid refrigerant. Then, the medium-temperature and high-pressure liquid refrigerant becomes a low-temperature and low-pressure liquid refrigerant after its pressure is reduced by a capillary tube (throttling unit). The low-temperature and low-pressure liquid refrigerant is transported to the evaporator where it 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.

[0027] In view of the above technical problems existing in the related art, the embodiments of the present application provide an air conditioner control method based on hybrid power supply. This method is applied to an air conditioner with a generator provided on the outdoor unit. The generator is used to be mechanically connected in series with the outdoor unit fan to generate electrical energy by the rotation of the outdoor unit fan and supply power to the compressor. This method uses the magnitude of the electrical energy generated by the outdoor unit fan and the rotational speed of the outdoor unit fan to intelligently adjust the power supply mode of the air conditioner, greatly improving the utilization rate of new energy power supply.

[0028] The following combines the drawings and details the air conditioner control method based on hybrid power supply provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0029] As Figure 1 shown, an air conditioner control method based on hybrid power supply provided by the embodiments of the present application may include the following steps 101 to step 103: Step 101, during the operation of the air conditioner, control the outdoor unit fan of the air conditioner to maintain the maximum rotational speed, and use the outdoor unit fan to drive the generator to generate electrical energy to supply power to the compressor of the air conditioner.

[0030] It can be understood that when the outdoor unit fan is running, it will drive the generator to run and generate electrical energy, and the electrical energy generated by the generator can also be used to supply power to the compressor. Moreover, when the outdoor unit fan runs at the maximum rotational speed, only a very small force is required to maintain its rotational speed. Therefore, the efficiency of electrical energy conversion is relatively high, and the waste of electrical energy provided by solar energy is also relatively small.

[0031] Specifically, in the above step 101, the step of controlling the outdoor unit fan of the air conditioner to maintain the maximum rotational speed may further include the following step 101a: Step 101a, after the air conditioner is powered on and started, use solar power supply and mains power supply to supply power to the outdoor unit fan, and control the outdoor unit fan to run at the maximum rotational speed.

[0032] Among them, after the outdoor unit fan reaches the maximum speed, the outdoor unit fan is used to drive the generator to generate electric energy to supply power to the compressor of the air conditioner.

[0033] Specifically, in the above step 101a, the step of controlling the outdoor unit fan to run at the maximum speed may further include the following steps 101a1 and 101a2: Step 101a1: Obtain the current speed of the outdoor unit fan and calculate the speed difference between the current speed and the maximum speed.

[0034] Step 101a2: Based on the speed difference, adjust the duty cycle of the input voltage of the outdoor unit fan to control the outdoor unit fan to run at the maximum speed.

[0035] Among them, the power supply mode of the outdoor unit fan is: solar power supply and mains power supply; during the operation of the outdoor unit fan at the maximum speed, the ratio of solar power supply and mains power supply remains constant.

[0036] Step 102: Determine the mains power demand of the air conditioner based on the operating frequency of the compressor and the light intensity of the current outdoor environment.

[0037] Exemplarily, the air conditioner can determine the operating frequency of the compressor according to parameters such as the indoor and outdoor environmental temperatures and the set temperature of the air conditioner, and then determine the total power demand of the air conditioner, and determine the power demand for mains power supply according to the power supply power of solar power supply.

[0038] Specifically, the above step 102 may further include the following steps 102a1 to 102a3: Step 102a1: Determine the current operating frequency of the compressor based on the current outdoor environmental temperature, and determine the total power supply demand of the air conditioner based on the current operating frequency of the compressor.

[0039] Step 102a2: Determine the first power supply power of solar power supply based on the light intensity of the current outdoor environment, and calculate the total power supply power based on the difference between the sum of the first power supply power and the second power supply power of the generator and the third power supply power.

[0040] Among them, the third power supply power is the power supply power provided by solar power supply in the power supply mode of the outdoor unit fan.

[0041] Step 102a3: Determine the difference between the total power supply demand and the total power supply power as the mains power demand of the air conditioner.

[0042] Exemplarily, after determining the urban power demand of the air conditioner, the power supply mode of the air conditioner can be determined accordingly.

[0043] Step 103: Based on the urban power demand of the air conditioner, the power supply power of the electric energy output by the generator, and the rotational speed of the outdoor unit fan, determine the power supply mode of the air conditioner, and supply power to the air conditioner according to the power supply mode of the air conditioner.

[0044] Among them, the power supply mode of the air conditioner includes any one of the following: solar power supply, mains power supply, hybrid power supply; the hybrid power supply includes: solar power supply and mains power supply.

[0045] Specifically, based on the urban power demand obtained in the above step 102, the step of determining the power supply mode of the air conditioner in the above step 103 may further include the following step 103a1 or step 103a2: Step 103a1: When the urban power demand is greater than or equal to zero, determine the hybrid power supply as the power supply mode of the air conditioner.

[0046] Step 103a2: When the urban power demand is less than zero, determine the solar power supply as the power supply mode of the air conditioner.

[0047] Exemplarily, when the urban power demand is less than zero, it means that the solar power supply can fully meet the power consumption demand of the air conditioner. At this time, only the mains power supply needs to be used to supply power to the outdoor unit fan for subsequent step judgment, and the air conditioner as a whole uses solar power supply.

[0048] Exemplarily, when the urban power demand is greater than or equal to zero, it means that the solar power supply cannot fully meet the power consumption demand of the air conditioner. At this time, a hybrid power supply mode of mains power supply plus solar power supply needs to be used to supply power to the air conditioner to meet the power consumption demand of the air conditioner.

[0049] In a possible implementation manner, the power supply mode can also be determined based on the rotational speed of the outdoor unit fan.

[0050] Specifically, the above step 103 may further include the following step 103b: Step 103b: When the rotational speed of the outdoor unit fan decreases, determine the mains power supply as the power supply mode of the air conditioner.

[0051] It should be noted that during the operation of the outdoor unit fan at the maximum rotational speed, the ratio of solar power supply and mains power supply remains constant. In this case, if the power generation capacity of the photovoltaic panel is insufficient, resulting in a decrease in the electric energy provided by the solar power supply, in order to keep the power supply ratio unchanged, the power supply power of the mains power supply will inevitably be reduced, thereby causing a decrease in the rotational speed of the outdoor unit fan.

[0052] For example, as Figure 2 shown, it is a detailed flowchart of the air conditioner control method based on hybrid power supply provided by the embodiment of the present application. Specifically, after the air conditioner is powered on and operates, the maximum speed of the outdoor unit fan is controlled by using mains power supply and solar power supply. The rotation of the outdoor unit fan drives the generator to generate electricity and supply power to the compressor. After the outdoor unit fan operates stably, the power supply capacity of the solar power supply can be judged by whether the speed of the outdoor unit fan drops. If the speed of the outdoor unit fan drops, it means that the power supply capacity of the solar power supply is already very low, unstable and of no use value. At this time, the mains power can be used to supply power to the air conditioner. If the speed of the outdoor unit fan is stable at the maximum speed, the power supply mode can be judged by the mains power demand. If the mains power demand is greater than or equal to zero, it means that the solar power supply cannot meet the power consumption demand. At this time, a hybrid power supply mode of mains power supply plus solar power supply is required for power supply; otherwise, solar power supply can be used.

[0053] It should be noted that the solar power supply in the embodiment of the present application refers to the electric energy generated by using solar energy, which can directly supply power to the solar photovoltaic panel, or the storage battery that stores the electric energy generated by the photovoltaic panel, or can also supply power to the photovoltaic panel and the storage battery at the same time.

[0054] For the air conditioner control method based on hybrid power supply provided by the embodiment of the present application, first, during the operation of the air conditioner, the outdoor unit fan of the air conditioner is controlled to maintain the maximum speed, and the generator is driven by the outdoor unit fan to generate electric energy to supply power to the compressor of the air conditioner; then, based on the operating frequency of the compressor and the light intensity of the current outdoor environment, the mains power demand of the air conditioner is determined; finally, based on the mains power demand of the air conditioner, the power supply power of the electric energy output by the generator, and the speed of the outdoor unit fan, the power supply mode of the air conditioner is determined, and the air conditioner is powered according to the power supply mode of the air conditioner; wherein, the power supply mode of the air conditioner includes any one of the following: solar power supply, mains power supply, hybrid power supply; the hybrid power supply includes: solar power supply and mains power supply. In this way, the power supply mode of the air conditioner is intelligently adjusted by using the magnitude of the electric energy generated by the outdoor unit fan and the speed of the outdoor unit fan, which greatly improves the utilization rate of new energy power supply.

[0055] It should be noted that for the air conditioner control method based on hybrid power supply provided in the embodiments of the present application, the execution subject can be an air conditioner control device based on hybrid power supply, or a control module in the air conditioner control device based on hybrid power supply for executing the air conditioner control method based on hybrid power supply.
