[0032] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0033] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0034] The following describes in detail the operating principle of the air conditioner involved in the embodiment of the present application:

[0035] like Figure 1 As shown in the figure, the compressor compresses the refrigerant (coolant) and transports it through a pipeline to the condenser. The high-temperature, high-pressure gaseous refrigerant releases heat in the condenser, becoming a medium-temperature, high-pressure liquid refrigerant. The medium-temperature, high-pressure liquid refrigerant then passes through a capillary tube (throttling element) to reduce its pressure, turning it into a low-temperature, low-pressure liquid refrigerant. The low-temperature, low-pressure liquid refrigerant is then transported to the evaporator, where it evaporates from liquid to gas, absorbing a significant amount of heat during the evaporation process. Finally, the low-temperature, low-pressure gaseous refrigerant in the evaporator is transported back to the compressor to participate in the next cycle. When the air conditioner is cooling, the outdoor unit's heat exchanger acts as the condenser, and the indoor unit's heat exchanger acts as the evaporator. Conversely, when the air conditioner is heating, the outdoor unit's heat exchanger acts as the evaporator, and the indoor unit's heat exchanger acts as the condenser.

[0036] As can be seen from the above, the compressor is a key component in enabling various functions of an air conditioner. Therefore, it requires a stable power supply to ensure the normal operation of these functions. In related art, air conditioners have a wide range of input voltages, typically 110 volts (V), 150V, 180V, or 220V, but there are strict restrictions on the input current. For example, the supply current required by a fixed-frequency compressor is typically 15 to 18 amperes (A), while the supply current required by a variable-frequency compressor is typically 3 to 5A.

[0037] The air conditioner power supply method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0038] like Figure 2As shown, a power supply device used in the air conditioner power supply method provided in an embodiment of the present application includes: a first power supply circuit, a second power supply circuit, a third power supply circuit and a power supply controller; the first power supply circuit is a solar power supply circuit, the second power supply circuit is a battery power supply circuit, and the third power supply circuit is an AC power supply circuit.

[0039] Illustratively, the air conditioner power supply method provided in the embodiment of the present application is executed by the power supply controller of the above-mentioned power supply device. The power supply controller can be a component in the power supply device independent of the air conditioner, or it can be a part of the power management circuit in the air conditioner.

[0040] Based on the above Figure 2 ,like Figure 3 As shown, an embodiment of the present application provides a method for powering an air conditioner, which may include the following steps 301 and 302:

[0041] Step 301: Calculate the power supply power when at least one of the first power supply circuit, the second power supply circuit, and the third power supply circuit is used for power supply, and obtain the power supply power under multiple different power supply modes.

[0042] Exemplarily, the above-mentioned multiple different power supply modes include: using the first power supply circuit alone for power supply, using the second power supply circuit alone for power supply, using the third power supply circuit alone for power supply, using the first power supply circuit and the second power supply circuit in combination for power supply, using the second power supply circuit and the third power supply circuit in combination for power supply, using the first power supply circuit and the third power supply circuit in combination for power supply, and using the first power supply circuit, the second power supply circuit and the third power supply circuit in combination for power supply.

[0043] Illustratively, when the power demand of the air conditioner is met, the power supply cost of the first power supply circuit is lower than the power supply cost of the second power supply circuit, and the power supply cost of the second power supply circuit is lower than the power supply cost of the third power supply circuit.

[0044] In one possible implementation, the power supply cost of the separate power supply is lower than the power supply cost of the combined power supply, that is, when both the separate power supply mode and the combined power supply mode can meet the power demand of the air conditioner, the power supply cost of the separate power supply mode is lower than the power supply cost of the combined power supply mode.

[0045] Based on this, the power supply costs of the above-mentioned multiple different power supply methods are from low to high as follows: using the first power supply circuit alone for power supply, using the second power supply circuit alone for power supply, using the third power supply circuit alone for power supply, using the first power supply circuit and the second power supply circuit in combination for power supply, using the second power supply circuit and the third power supply circuit in combination for power supply, using the first power supply circuit and the third power supply circuit in combination for power supply, and using the first power supply circuit, the second power supply circuit and the third power supply circuit in combination for power supply.

[0046] It should be noted that, for the above-mentioned combined power supply mode, the power supply power of the combined power supply mode is the sum of the power supply powers of the various power supply circuits included therein.

[0047] Step 302: Based on the power supply power under different power supply modes and the rated power of the air conditioner when running in the current working mode, select a target power supply mode with the lowest power supply cost from the multiple different power supply modes to power the air conditioner.

[0048] For example, when the air conditioner is turned on, the required power supply, i.e., the rated power, is determined based on the air conditioner's current operating mode. The second power supply circuit can then provide power for the compressor during a preset phase. Specifically, during the compressor's preheating phase, the battery provides power.

[0049] It should be noted that when the air conditioner is not running, the electricity generated by the solar panels can be stored in the battery to avoid waste of resources.

[0050] Optionally, in an embodiment of the present application, the above-mentioned multiple power supply modes can be screened according to the power supply power that each power supply mode can provide.

[0051] Specifically, the above step 302 may include the following steps 302a and 302b:

[0052] Step 302a: Filter out candidate power supply modes whose power supply power is greater than the rated power from the multiple different power supply modes.

[0053] Step 302b: Based on the power supply cost of each of the candidate power supply modes, select the target power supply mode to power the air conditioner.

[0054] For example, based on the power provided by each power supply method, a preliminary screening can be performed on the multiple power supply methods to select candidate power supply methods that meet the power requirements of the air conditioner. A target power supply method with the lowest power supply cost is then selected from the candidate power supply methods, and the air conditioner is powered using the target power supply method.

[0055] Specifically, the above step 302b may further include any one of the following steps 302b1 to 302b3:

[0056] Step 302b1: When the power supplied by the first power supply mode is greater than the rated power, determine the first power supply mode as the target power supply mode.

[0057] The first power supply mode is a power supply mode in which the first power supply circuit is used alone for power supply.

[0058] For example, since the first power supply circuit has the lowest power supply cost, when the power supply power of the first power supply circuit is greater than the rated power, the first power supply circuit can be preferentially used to power the air conditioner.

[0059] Step 302b2: When the power supply power of the first power supply mode is less than or equal to the rated power and the power supply power of the second power supply mode is greater than the rated power, determine the second power supply mode as the target power supply mode.

[0060] The second power supply mode is a power supply mode that uses the first power supply circuit and the second power supply circuit in combination to supply power.

[0061] For example, since the electric energy stored in the battery is also provided by the solar panel, when the power supply power of the first power supply circuit cannot meet the power demand of the air conditioner, but the power supply power of the power supply method using the first power supply circuit and the second power supply circuit in combination can meet the power demand of the air conditioner, the air conditioner can be powered by the power supply method using the first power supply circuit and the second power supply circuit in combination.

[0062] Step 302b3: When the power supply power of the first power supply mode is less than or equal to the rated power, and the power supply power of the second power supply mode is less than or equal to the rated power, if the power supply power of the second power supply mode is greater than a preset threshold, the third power supply mode is determined as the target power supply mode; otherwise, the fourth power supply mode is determined as the target power supply mode.

[0063] The third power supply mode is a power supply mode in which the first power supply circuit, the second power supply circuit and the third power supply circuit are used in combination; the fourth power supply mode is a power supply mode in which the third power supply circuit is used alone.

[0064] For example, when the power supply power of the power supply method using the first power supply circuit and the second power supply circuit in combination still cannot meet the power demand of the air conditioner, the air conditioner can be powered by a power supply method using the first power supply circuit, the second power supply circuit and the third power supply circuit in combination.

[0065] For example, in order to ensure the stability of power supply to the air conditioner, it is necessary to determine whether the power supply power of the power supply method using a combination of the first power supply circuit and the second power supply circuit is greater than a preset threshold. If so, the third power supply method is used to power the air conditioner; otherwise, the fourth power supply method is needed to power the air conditioner.

[0066] Illustratively, after step 302b2, step 302 may further include any one of the following steps 302c1, 302c2, and 302c3:

[0067] Step 302c1: Determine whether the supply voltage of the first power supply circuit is greater than the supply voltage of the second power supply circuit.

[0068] Step 302c2: When the supply voltage of the first power supply circuit is greater than the supply voltage of the second power supply circuit, the first power supply circuit and the second power supply circuit are connected in series to supply power to the air conditioner.

[0069] Step 302c3: When the supply voltage of the first power supply circuit is less than or equal to the supply voltage of the second power supply circuit, the first power supply circuit and the second power supply circuit are connected in parallel to supply power to the air conditioner.

[0070] It should be noted that, under normal circumstances, different power supply circuits can be connected in parallel to power the air conditioner. However, to avoid wasting energy when using the second power supply method, the air conditioner can be powered by connecting the first power supply circuit and the second power supply circuit in series. When using the series power supply method, the excess energy generated by the solar panel can be used to charge the battery.

[0071] It should be noted that in order to power the air conditioner by connecting the first power supply circuit and the second power supply circuit in series, the supply voltage of the first power supply circuit needs to be greater than the supply voltage of the second power supply circuit, that is, the output voltage of the solar panel needs to be greater than the output voltage of the battery. Otherwise, the battery will reversely supply power to the solar panel, resulting in energy waste and even damage to electronic components.

[0072] Furthermore, after the above step 302c2, the air conditioner power supply method provided in the embodiment of the present application may further include the following steps 303 and 304:

[0073] Step 303: monitor the first supply voltage of the first power supply circuit and the second supply voltage of the second power supply circuit in real time.

[0074] Step 304: When the first power supply voltage is less than or equal to the second power supply voltage, adjust the power supply mode of the first power supply circuit and the second power supply circuit from series connection to parallel connection.

[0075] For example, when the air conditioner is powered by connecting the first power supply circuit and the second power supply circuit in series, it is necessary to monitor the first power supply voltage and the second power supply voltage in real time. When the series power supply condition is not met, switching is required in a timely manner.

[0076] Optionally, in an embodiment of the present application, since the output power of the solar panel will change with the change of light intensity, and the electric energy generated and stored by the battery will also decrease over time, it is necessary to monitor it in real time so that timely adjustments can be made to ensure the stability of power supply.

[0077] For example, after step 302b3, the air conditioner power supply method provided in the embodiment of the present application may further include the following step 305:

[0078] Step 305: monitor the total power supply power of the first power supply circuit and the second power supply circuit in real time. If the total power supply power is less than a preset threshold, disconnect the first power supply circuit and the second power supply circuit, and use the third power supply circuit alone to power the air conditioner.

[0079] It is understandable that when the total power supply power of the first power supply circuit and the second power supply circuit is less than a preset threshold, the electric energy they can provide is relatively low. At this time, the air conditioner can be powered only by the third power supply circuit.

[0080] The air conditioner power supply method provided in the embodiment of the present application first calculates the power supply when using at least one of the first power supply circuit, the second power supply circuit, and the third power supply circuit to provide power, thereby obtaining the power supply power under multiple different power supply modes. Then, based on the power supply power under the different power supply modes and the rated power of the air conditioner when operating in the current working mode, a target power supply mode with the lowest power supply cost is selected from the multiple different power supply modes to power the air conditioner. In this way, by calculating the power supply power of various power supply modes and selecting the power supply mode with the lowest power supply cost to power the air conditioner, not only the utilization rate of the electric energy provided by solar energy is improved, but also the user's electricity cost can be reduced to a certain extent.

[0081] It should be noted that the air conditioner power supply method provided in the embodiments of the present application can be executed by a power supply device, or a control module in the power supply device for executing the air conditioner power supply method. In the embodiments of the present application, the power supply device provided in the embodiments of the present application is described by taking the power supply device executing the air conditioner power supply method as an example.

[0082] It should be noted that in the embodiments of the present application, the air conditioner power supply method shown in the above-mentioned method drawings is described by way of example in conjunction with one of the drawings in the embodiments of the present application. In specific implementation, the air conditioner power supply method shown in the above-mentioned method drawings can also be implemented in conjunction with any other combinable drawings shown in the above-mentioned embodiments, and will not be further described here.
