Description

Air conditioner control methods, devices, cloud computing equipment, electronic equipment and media Technical Field

[0001] This application relates to the technical fields of air conditioners, photovoltaic equipment, etc., and in particular to a control method, device, cloud computing equipment, electronic equipment and medium for an air conditioner. Background Technology

[0002] Existing air conditioners prioritize user comfort above all else. For example, when the room temperature deviates from the user's set temperature, the air conditioner will provide cooling or heating at the optimal speed to maintain the room temperature near the set temperature. However, when a home is equipped with a photovoltaic energy storage system, this type of air conditioner does not take into account the status of the photovoltaic and energy storage systems.

[0003] The existing air conditioning operation mode consumes excessive battery or grid power when photovoltaic power is insufficient, and cannot effectively absorb photovoltaic power when photovoltaic power is sufficient, resulting in the photovoltaic and energy storage system not being able to play its maximum value and the household energy self-sufficiency rate being low. Summary of the Invention

[0004] Therefore, the purpose of this application is to propose a control method, device, cloud computing equipment, electronic equipment, medium and computer program product based on a regulator, which adjusts the number of air conditioners and the air outlet direction of the air conditioners in the start-up state by combining the power surplus of the photovoltaic device. When the photovoltaic power is sufficient, the photovoltaic absorption rate can be improved, and the air conditioners can bring a better temperature experience to users by consuming photovoltaic power.

[0005] This application provides a method for controlling an air conditioner, which supplies power to a load via a power supply system. The power supply system includes a photovoltaic device and a battery device, and the load includes the air conditioner. The method includes: acquiring target data of the power supply system, wherein the target data of the power supply system includes photovoltaic power data of the photovoltaic device and battery data of the battery device; based on the target data of the power supply system, determining the target range of the photovoltaic device's power from a plurality of power ranges, wherein the plurality of power ranges includes at least two of a power surplus range, a power deficiency range, and a power transition range, and the range boundaries of the plurality of power ranges are associated with at least a photovoltaic surplus power threshold and a battery threshold; and based on the target range, controlling the on / off state of the air conditioner to change the number of air conditioners in the on state, and / or controlling the air outlet direction of the air conditioner.

[0006] For example, the battery threshold includes a first energy threshold, and the power range division includes: when the photovoltaic power is greater than the photovoltaic surplus power threshold and the remaining battery energy is greater than the first energy threshold, it is the power surplus range.

[0007] For example, the battery threshold further includes a second power threshold, which is less than the first power threshold; the power supply system further includes a grid power supply device, and the boundaries of the plurality of power intervals are also associated with a grid power draw threshold, wherein the grid power draw includes the power drawn by the load from the grid power supply device; the power interval division further includes: when the remaining battery power is less than the second power threshold and the battery device draws power, or when the grid power draw is greater than the grid power draw threshold, it is a power deficiency interval.

[0008] For example, the battery threshold further includes a second power threshold, which is less than the first power threshold; the battery threshold includes a charging power threshold; the power range division further includes: when the remaining battery power is less than the second power threshold and the charging power of the battery device is less than the charging power threshold, it is a power insufficiency range.

[0009] For example, the power range division further includes: when the photovoltaic power is less than the surplus power threshold, or when the remaining battery power is less than the first power threshold, it is the power transition range; or when the remaining battery power is greater than the second power threshold and the grid power is less than or equal to the grid power threshold, it is the power transition range.

[0010] For example, the power range division further includes: when the photovoltaic power is less than or equal to the photovoltaic surplus power threshold and the remaining battery charge is greater than or equal to the second charge threshold, or when the remaining battery charge is less than or equal to the first charge threshold and the charging power of the battery device is greater than or equal to the charging power threshold, the power transition range is defined as such.

[0011] For example, controlling the on / off state of the air conditioner to change the number of air conditioners in the on / off state based on the target range includes: when the target range is the power surplus range, determining a target air conditioner from at least one air conditioner in the off state and controlling the target air conditioner to turn on; when the target range is the power shortage range, determining a target air conditioner from at least one air conditioner in the on / off state and controlling the target air conditioner to turn off.

[0012] For example, when the target range is the power surplus range, the power of the target air conditioner is less than the power of the photovoltaic device, and the power difference between the power of the target air conditioner and the power of the photovoltaic device is less than or equal to the power difference between the power of the air conditioner and the power of the photovoltaic device in other off states.

[0013] For example, when the target range is the power shortage range, the power of the target air conditioner is greater than the power taken from it, and the power difference between the power of the target air conditioner and the power taken from it is less than or equal to the power difference between the power of the air conditioner in other operating states and the power taken from it. The power taken from it includes the sum of the power taken from the battery device and the power taken from the grid.

[0014] For example, controlling the on / off state of the air conditioner to change the number of air conditioners in the on / off state based on the target interval includes: when multiple candidate air conditioners are included, determining the sorting information of the multiple candidate air conditioners based on the target interval, wherein the sorting information is associated with air conditioner usage preferences and / or historical usage information; determining the target air conditioner from the multiple candidate air conditioners based on the sorting information, and controlling the on / off state of the target air conditioner.

[0015] For example, controlling the air outlet direction of the air conditioner based on the target range includes: when the target range is the power surplus range, controlling the air outlet direction of the air conditioner towards the energy storage object; when the target range is the power transition range, maintaining the current air outlet direction of the air conditioner; and when the target range is the power deficiency range, adjusting the air outlet direction of the air conditioner to the user-defined direction.

[0016] For example, the method further includes: controlling the set temperature of the air conditioner based on the target range and the current operating mode of the air conditioner.

[0017] For example, controlling the set temperature of the air conditioner based on the target range and the current operating mode of the air conditioner includes: when the target range is the power surplus range: if the current operating mode is cooling mode, lowering the set temperature of the air conditioner; if the current operating mode is heating mode, raising the set temperature of the air conditioner; when the target range is the power transition range: if the current operating mode is cooling mode or heating mode, maintaining the set temperature of the air conditioner; when the target range is the power deficiency range: if the current operating mode is cooling mode, raising the set temperature of the air conditioner; if the current operating mode is heating mode, lowering the set temperature of the air conditioner.

[0030] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0031] Current air conditioners prioritize user comfort above all else. In some cases, when the room temperature deviates from the user's set temperature, the air conditioner will provide cooling or heating at the optimal speed to maintain the room temperature near the set temperature. However, when a home is equipped with a photovoltaic (PV) energy storage system, this type of air conditioner operation does not take into account the status of the PV and storage systems. This operating mode consumes excessive battery or grid power when PV is insufficient, and cannot effectively absorb PV power when it is abundant. Consequently, the PV-storage system cannot reach its full potential, resulting in low household energy self-sufficiency.

[0032] Based on this, the present invention proposes a control method for an air conditioner, which adjusts the number of air conditioners in operation and / or the air outlet direction of the air conditioner in combination with the power range of the photovoltaic device. When the photovoltaic power is sufficient, the photovoltaic absorption rate can be improved, and when the photovoltaic power is insufficient, the power of the battery or grid can be consumed more rationally.

[0033] Figure 1 is a flowchart of a control method of a controller according to an embodiment of this application.

[0034] As shown in Figure 1, the control methods of the air conditioner include S101-S103.

[0035] S101, acquire target data of the power supply system, wherein the target data of the power supply system includes photovoltaic power data of photovoltaic device and battery data of battery device.

[0036] S102, based on the target data of the power supply system, determine the target range in which the power of the photovoltaic device is located from the multiple power ranges obtained.

[0037] S103, based on the target range, controls the on / off state of the air conditioner to change the number of air conditioners in the on state, and / or controls the air outlet direction of the air conditioner.

[0038] Among them, the multiple power ranges include at least two of the power surplus range, power shortage range and power transition range, and the boundaries of the multiple power ranges are at least associated with the photovoltaic surplus power threshold and the battery threshold.

[0039] For example, the air conditioner control method of this application is applied to a scenario where photovoltaic equipment is installed. Power is supplied to the load through a power supply system, which includes a photovoltaic device and a battery device, such as a storage battery. The load includes an air conditioner. Of course, for all appliances in the house, the power sources include photovoltaic devices, battery devices, and the power grid. The photovoltaic device can supply power to the load (e.g., the air conditioner) and can also charge the battery device. This application aims to improve the user experience of the air conditioner by controlling the air conditioner to increase its consumption of photovoltaic power when there is a surplus of photovoltaic power.

[0040] For example, firstly, target data for the power supply system is acquired. This target data includes photovoltaic power data from the photovoltaic device and battery data from the battery device. Based on this target data, the target power range of the photovoltaic device is determined from multiple power ranges. For example, these power ranges can be categorized as a power surplus range, a power deficiency range, and a power transition range. The on / off state of the air conditioner is then controlled according to the target range to change at least one of the following: the number of air conditioners currently on and the direction of airflow from the air conditioner.

[0041] The air conditioner control method of this application adjusts the number of air conditioners in operation and the air outlet direction of the air conditioners in combination with the power range of the photovoltaic device. When the photovoltaic power is sufficient, it can improve the photovoltaic absorption rate and when the photovoltaic power is insufficient, it can more rationally consume battery or grid power.

[0042] As an example, the battery threshold includes a first energy threshold; the power range division includes: when the photovoltaic power is greater than the photovoltaic surplus power threshold and the remaining battery energy is greater than the first energy threshold, it is a power surplus range.

[0043] For example, battery data includes the remaining battery charge (SOC). SOC (State of Charge) represents the available state of the remaining battery charge, i.e., the remaining charge. When the remaining battery charge is greater than a first charge threshold, this first charge threshold can be denoted as SOC_up_thr. This first charge threshold can be understood as an upper limit for the charge, expressed as a percentage, for example, 80%. When the remaining battery charge (SOC) is greater than 80%, it indicates that the battery has sufficient energy reserves. Furthermore, as the remaining battery charge (SOC) increases, the maximum charging power decreases. If the photovoltaic power is greater than the photovoltaic surplus power threshold at this point, it indicates that there is surplus photovoltaic power, and this range is defined as the power surplus range. In this case, air conditioners can be used to consume more photovoltaic power.

[0044] Wherein, surplus power = grid-connected power + curtailed power; if there is no valid data for curtailed power, it is defaulted to 0. Surplus power threshold. Where n is the number of air conditioners with the linkage function currently enabled. f(i) is the minimum power value among all air conditioners waiting to be turned on.

[0045] As an example, the battery threshold also includes a second energy threshold, which is less than the first energy threshold; the power supply system also includes a grid power supply device, and the boundaries of multiple power ranges are also associated with grid power draw thresholds, wherein grid power draw includes the power drawn by the load from the power grid device; the power range division also includes: when the remaining battery energy is less than the second energy threshold and the battery device draws power, or when the grid power draw is greater than the grid power draw threshold, it is a power shortage range.

[0046] For example, the second power threshold can be denoted as SOC_low_thr, with the unit being percentage. This second power threshold is understood as a lower limit for power consumption; for example, it can be set to 10%. The grid power consumption threshold is denoted as Supply_q1. When the remaining battery power (SOC) is less than the lower limit and the battery is still drawing power from the system, it indicates that the battery has very little remaining power and is still supplying power to the load. This also indicates that the photovoltaic system has stopped generating electricity or its power generation is insufficient to support the household load, thus defining this interval as a power deficiency interval. Conversely, even if the remaining battery power (SOC) is high (e.g., greater than the second power threshold), if the grid power consumption exceeds the grid power consumption threshold (i.e., grid power is being drawn), it indicates that the household load is very high, and the photovoltaic system combined with the battery discharge cannot support the household load. This interval is also defined as a power deficiency interval, and in this case, the air conditioning settings need to be adjusted to reduce power consumption.

[0047] This application provides two examples of methods for defining the power shortage range. In addition to the above-mentioned method of determining the power shortage range when the remaining battery power is less than the second power threshold and the power drawn from the battery device or the grid is greater than the grid power threshold, the following other example is also included.

[0048] As an example, the battery threshold also includes a second energy threshold, which is less than the first energy threshold; the battery threshold includes a charging power threshold; the power range division also includes:

[0049] The power shortage range is defined as the situation where the remaining battery power is less than the second power threshold and the charging power of the battery device is less than the charging power threshold.

[0050] For example, let the charging power threshold be denoted as charge_q1. The battery device is charged through the photovoltaic device. Therefore, when the remaining battery charge SOC is less than the second charge threshold and the charging power of the battery device is less than the charging power threshold, it also indicates that the photovoltaic has stopped generating electricity or the power generation is insufficient to support the household load. This range is determined to be the power shortage range. At this time, the air conditioner settings are adjusted to reduce the power consumption of the air conditioner.

[0051] As an example, the power range division also includes: a power transition range when the photovoltaic power is less than the first surplus power threshold, or when the remaining battery capacity is less than the first capacity threshold; or

[0052] The power transition range is defined as the condition where the remaining battery power is greater than the second power threshold and the grid power draw is less than or equal to the grid power draw threshold.

[0053] For example, this application sets a power transition interval between a power surplus interval and a power shortage interval, specifically for the first method of dividing the power shortage interval. The power transition interval is defined as the situation where the photovoltaic power is less than a first surplus power threshold, or the remaining battery charge is less than a first charge threshold. Alternatively, the power transition interval is defined as the situation where the remaining battery charge is greater than a second charge threshold and the grid power draw is less than or equal to the grid power draw threshold.

[0054] As an example, the power range division also includes: a power transition range when the photovoltaic power is less than or equal to the photovoltaic surplus power threshold and the remaining battery charge is greater than or equal to the second charge threshold, or when the remaining battery charge is less than or equal to the first charge threshold and the charging power of the battery device is greater than or equal to the charging power threshold.

[0055] For example, regarding the second method of dividing the power shortage range, if the photovoltaic power is less than or equal to the photovoltaic surplus power threshold and the remaining battery charge is greater than or equal to the second charge threshold, the range is determined to be a power transition range. Alternatively, if the remaining battery charge is less than or equal to the first charge threshold and the charging power of the battery device is greater than or equal to the charging power threshold, the range is determined to be a power transition range.

[0056] Figure 2 is a partition diagram of an embodiment of this application.

[0057] As shown in Figure 2, the power surplus interval is defined as follows: when the remaining battery charge (SOC) is greater than the first charge threshold (SOC_up_thr) and the photovoltaic power is greater than the surplus power threshold (Surplus_f1). When the remaining battery charge (SOC) is less than the second charge threshold (SOC_low_thr) and the power drawn from the battery device or the grid is greater than the grid power threshold (Supply_q1), the power shortage interval is defined as follows: All intervals outside the power surplus and power shortage intervals are power transition intervals. This zoning method is the first zoning method.

[0058] Figure 3 is a partition diagram of another embodiment of this application.

[0059] As shown in Figure 3, the power surplus interval is defined as follows: when the remaining battery charge (SOC) is greater than the first charge threshold (SOC_up_thr) and the photovoltaic power is greater than the surplus power threshold (Surplus_f1). When the remaining battery charge (SOC) is less than the second charge threshold (SOC_low_thr) and the battery device's charging power is less than the charging power threshold (charge_q1), the power shortage interval is defined as follows: all intervals except the surplus and shortage intervals are transition intervals. This partitioning method is the second partitioning method.

[0060] Regarding the first partitioning method, referring to Figure 2, there exists a situation where, when in the power transition interval (battery SOC greater than SOC_low_thr), if the grid power draw at a certain moment exceeds the grid power draw threshold Supply_q1, the system directly jumps from the power transition interval to the power shortage interval, regardless of the battery SOC value. This is equivalent to having no battery SOC as a buffer (i.e., battery SOC is not considered), leading to redundancy and drastic air conditioning switching. Therefore, in the second partitioning method, the definition of grid power draw exceeding the threshold (grid power draw > grid power draw threshold Supply_q1) is removed in the power shortage interval, ensuring that the remaining battery SOC acts as a buffer during the transition between the power shortage interval and the power transition interval.

[0061] For different zones, this application adjusts the number of air conditioners in the on state and the air outlet direction of the air conditioners.

[0062] The following provides a detailed explanation of how to control the on / off status of air conditioners to change the number of air conditioners that are currently on.

[0063] As an example, based on a target range, controlling the on / off state of air conditioners to change the number of air conditioners in the on / off state includes:

[0064] If the target range is a power surplus range, identify the target air conditioner from at least one air conditioner that is in the off state, and control the target air conditioner to turn on.

[0065] If the target range is a power shortage range, identify the target air conditioner from at least one air conditioner that is turned on, and control the target air conditioner to turn off.

[0066] For example, the air conditioner regulation strategy of this application is applicable to scenarios with multiple air conditioners and no one in the room. When the target range is a power surplus range, the photovoltaic consumption of the air conditioner should be increased. A target air conditioner is determined from at least one air conditioner that is in a powered-off state, and the target air conditioner is turned on. It can be understood that when the target range is a power surplus range, the target air conditioner is turned on to increase photovoltaic consumption. When the target range is a power deficiency range, the photovoltaic consumption of the air conditioner should be reduced. A target air conditioner is determined from at least one air conditioner that is in a powered-on state, and the target air conditioner is turned off. It can be understood that when the target range is a power deficiency range, the target air conditioner is turned off to reduce photovoltaic consumption. The number of target air conditioners can be one or more. When the target air conditioner is turned off, the system continues to operate until the user's original on / off settings are restored. For example, the user initially sets one air conditioner to be on, increases the number of on-duty air conditioners to 10 after power surplus, and turns them off until only the initial one air conditioner remains after power deficiency.

[0067] It should be noted that the above-described process of turning on and off the target air conditioner is a real-time process. For example, when the target range is a power surplus range, after turning on one target air conditioner, if the target range is still in a power surplus range, the action is executed again, and then another target air conditioner is turned on. A certain preset time interval can be allowed between each action.

[0068] As an example, when the target range is a power surplus range, the power of the target air conditioner is less than the power of the photovoltaic device, and the power difference between the target air conditioner and the photovoltaic device is less than or equal to the power difference between the air conditioner and the photovoltaic device in other off states.

[0069] For example, when the target range is a power surplus range, the selection principle for turning on the target air conditioner among all the air conditioners in the off state is: the power of the target air conditioner is less than the power of the photovoltaic device. This can be understood as the power consumed by the target air conditioner being less than the surplus power of the photovoltaic device. Furthermore, the power of the target air conditioner is the closest to the surplus power of the photovoltaic device. Here, the power of the air conditioner can be defined as: the rated power of the air conditioner, or the average operating power of the air conditioner calculated based on historical data of room temperature, outdoor ambient temperature, user-set temperature, and operating mode, or power under other definitions.

[0070] As an example, when the target range is a power shortage range, the power of the target air conditioner is greater than the power taken from it, and the power difference between the power of the target air conditioner and the power taken from it is less than or equal to the power difference between the power of the air conditioner and the power taken from it in other operating states. The power taken from it includes the sum of the power taken from the battery device and the power taken from the grid.

[0071] For example, when the target range is a power shortage range, the selection principle for shutting down the target air conditioner among all the air conditioners that are turned on is as follows: the power of the target air conditioner is greater than its power consumption. This means that the operating power of the target air conditioner is greater than its power consumption, so turning it off saves the current power consumption. Furthermore, the power of the target air conditioner is closest to its power consumption. The power consumption includes the battery power plus the grid power. The power of the target air conditioner can be its current operating power or the average operating power of the air conditioner over the previous T minutes.

[0072] As an example, as shown in Figure 4, based on the target range, the on / off state of the air conditioner is controlled to change the number of air conditioners in the on state, including S401-S402.

[0073] S401, when multiple candidate air conditioners are included, the ranking information of the multiple candidate air conditioners is determined based on the target interval, wherein the ranking information is associated with air conditioner usage preferences and / or historical usage information.

[0074] S402, based on the sorting information, determines the target air conditioner from multiple candidate air conditioners and controls the on / off state of the target air conditioner.

[0075] For example, when the target range is a power surplus range or a power shortage range, it is necessary to adjust the number of air conditioners currently running. If there are multiple candidate air conditioners, they can be sorted according to the target range. For instance, if the target range is a power surplus range, the sorting information might prioritize air conditioners that need to be turned on; if the target range is a power shortage range, the sorting information might prioritize air conditioners that need to be turned off. The sorting information is also associated with air conditioner usage preferences and / or historical usage information. Based on the sorting information, the target air conditioner is determined from the multiple candidate air conditioners. For example, the air conditioner ranked higher can be preferentially selected when turning the air conditioner on or off.

[0076] For example, when the target range is a power surplus range, when sorting multiple candidate air conditioners that are in a off state, air conditioners with a power output less than that of the photovoltaic device are ranked before those with a power output greater than or equal to that of the photovoltaic device. Among the air conditioners with a power output less than that of the photovoltaic device, the air conditioner with a power output closest to that of the photovoltaic device is ranked first. The other air conditioners are ranked according to the power difference between their power output and that of the photovoltaic device, with smaller power differences ranked higher. Based on the ranking information, the air conditioner ranked first among the candidate air conditioners is selected as the target air conditioner, and the target air conditioner is turned on.

[0077] When the power of the photovoltaic device is in the transition range, the number of air conditioners that are turned on does not change.

[0078] The following is a detailed explanation of how to control the airflow direction of an air conditioner.

[0079] As an example, controlling the airflow direction of the air conditioner based on a target range includes:

[0080] When the target range is a power surplus range, control the air outlet direction of the air conditioner to be directed toward the energy storage object;

[0081] When the target range is a power transition range, maintain the current air outlet direction of the air conditioner;

[0082] If the target range is a power deficiency range, adjust the air conditioner's airflow direction to the direction set by the user.

[0083] For example, when the target range is a power surplus range, the air outlet direction of the air conditioner is controlled to be directed towards the energy storage object, such as a wall that stores cold or heat. For instance, in cooling mode, when the air conditioner is installed near the ceiling, the air outlet is adjusted to face upwards to cool the ceiling and achieve the purpose of cold storage. In heating mode, when the air conditioner is installed near the ceiling, the air outlet is adjusted to face upwards to heat the ceiling and achieve the purpose of heat storage.

[0084] For example, when the target range is a power transition range, the current airflow direction of the air conditioner remains unchanged. When the target range is a power deficiency range, the airflow direction of the air conditioner is adjusted to the user-set direction to improve the user's temperature experience.

[0085] This application enhances the heat and cold storage capacity of air conditioners by adjusting the airflow direction to heat and cool the walls when there is a lot of photovoltaic power.

[0086] In addition to adjusting the number of air conditioners in operation and the air outlet direction of the air conditioners according to the power range, this application also adjusts the set temperature of the air conditioners.

[0087] As an example, the control method for air conditioners also includes controlling the set temperature of the air conditioner based on the target range and the current operating mode of the air conditioner.

[0088] For example, the current operating mode includes heating or heating mode, and the set temperature of the air conditioner is adjusted according to the different power ranges and the different current operating modes of the air conditioner.

[0089] As an example, controlling the set temperature of the air conditioner based on the target range and the current operating mode of the air conditioner includes:

[0090] If the target range is a power surplus range: if the current operating mode is cooling mode, lower the air conditioner's set temperature; if the current operating mode is heating mode, raise the air conditioner's set temperature.

[0091] When the target range is the power transition range: if the current operating mode is cooling mode or heating mode, maintain the set temperature of the air conditioner;

[0092] If the target range is a power shortage range: if the current operating mode is cooling mode, increase the air conditioner's set temperature; if the current operating mode is heating mode, decrease the air conditioner's set temperature.

[0093] For example, when the target range is a power surplus range, the air conditioner can absorb more photovoltaic power. When the air conditioner's current operating mode is cooling mode, the set temperature is lowered. For instance, if the user initially sets the temperature to 26℃, without considering the photovoltaic power surplus, the air conditioner would cool at the user's set temperature of 26℃. However, considering the photovoltaic power surplus, the air conditioner can absorb more photovoltaic power and simultaneously improve the cooling effect. By adjusting, the final set temperature of the air conditioner is 25.5℃, resulting in a stronger cooling effect. If the air conditioner's current operating mode is heating mode, in order to increase the air conditioner's absorption of photovoltaic power, the set temperature can be increased. For example, if the user sets the temperature to 28℃ in winter, by adjusting, the final set temperature of the air conditioner is 28.5℃, resulting in a stronger heating effect.

[0094] For example, when the target range is the power transition range, the set temperature of the air conditioner is maintained unchanged regardless of whether the current operating mode is cooling mode or heating mode.

[0095] For example, when the target range is a power deficiency range, the air conditioner's power consumption can be reduced. When the air conditioner's current operating mode is cooling mode, the set temperature is increased. For example, if the user initially sets the temperature to 26°C, adjusting it may result in a final set temperature of 26.5°C, weakening the cooling effect. When the air conditioner's current operating mode is heating mode, the set temperature can be lowered to reduce the amount of photovoltaic power consumed by the air conditioner. For example, if the user sets the temperature to 28°C in winter, without considering insufficient photovoltaic power, the air conditioner would heat at the user's set temperature of 28°C. However, considering insufficient photovoltaic power, the air conditioner reduces photovoltaic power consumption, for example, adjusting it to a final set temperature of 27.5°C, weakening the heating effect. In some examples, the set temperature can be gradually lowered from 27.5°C, but it cannot fall below the lower limit of the user's set comfortable temperature.

[0096] The adjustment strategies for the above air conditioners are summarized in Table 1 below.

[0099]

[0100] It should be noted that the above air conditioner adjustment strategy only applies to scenarios where the room is unoccupied. For occupied rooms, the air conditioner will not be activated. For example, a person sensor can be installed in the room to determine whether someone is in the room.

[0101] It should be noted that when there are multiple air conditioners, one air conditioner can be operated every Tmin, and this method will be executed by the cloud to avoid operating all air conditioners at the same time.

[0102] The air conditioner control method of this application increases air conditioning power consumption and improves photovoltaic absorption rate by turning on the air conditioners one by one when there is abundant photovoltaic power, and also plays a role in storing cold or heat for the house. When there is little photovoltaic power, the air conditioners are turned off one by one to reduce air conditioning power consumption.

[0103] This application also proposes a control device for an air conditioner.
