[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Photovoltaic air conditioners mostly use batteries for energy storage, but batteries have disadvantages such as high price, short life, high maintenance and recycling costs, and serious environmental pollution after being discarded. In addition, the energy conversion of "light-electricity-cold" during cooling also has high energy loss.

[0028] Therefore, the present invention provides an energy storage air conditioner and a control method thereof, which reduces the use of storage batteries on the basis of photovoltaic air conditioners, and adds a cold storage device as another energy storage functional unit, uses cold storage instead of electricity storage, and adjusts the energy conversion path to "light-cold", thereby reducing the loss in the energy conversion process, reducing the use of storage batteries, reducing the production cost of energy storage air conditioners, and reducing environmental pollution. At the same time, the energy storage process of the air conditioner is controlled according to meteorological data, and a suitable energy storage method is selected without affecting the cooling comfort of the air conditioner, so that the air conditioner can be operated at the lowest possible cost, reducing the economic expenditure of users.

[0029] According to an embodiment of the present invention, a control method for an air conditioner is provided, wherein the air conditioner has a photovoltaic component and a battery; the electric energy generated by the photovoltaic component can be stored in the battery; the air conditioner can be additionally provided with a cold storage device; the electric energy generated by the photovoltaic component can also be stored in the cold storage device in the form of cold.

[0030] The air conditioner in this solution is a photovoltaic energy storage air conditioner, and the energy storage includes a photovoltaic power generation unit, a prediction unit, an energy storage unit, and a cold storage device. The energy storage unit is a battery, and the photovoltaic power generation unit is a photovoltaic power generation panel, which can convert solar energy into electrical energy and store it in the energy storage unit. The cold storage device is a selective external device that can be selectively installed according to local climatic conditions. The energy storage structure of the hybrid energy storage air conditioner is adjusted according to the comfort of seasonal ambient temperature. The economy of the air conditioner is the overall goal, and the cost of use is reduced by reducing the capacity and frequency of use of the battery. After the cold storage device is connected to the air conditioning system, the electric energy generated by the photovoltaic power generation unit can also drive the cold storage device to generate cold, thereby storing the electric energy in the form of cold.

[0031] The medium in the cold storage device can be set to water. The cold storage device can also select other media that are not prone to phase change or have a larger phase change temperature range as the cold storage medium to reduce the pressure exerted by the medium on the cold storage device during cold storage. The cold stored in the cold storage device can be directly used for refrigeration, thereby reducing the loss of energy conversion and improving the operating efficiency of the photovoltaic air conditioner.

[0032] The prediction unit can use the prediction model to predict the amount of electricity generated by the photovoltaic power generation unit. According to the prediction results, the power resources can be accurately dispatched to ensure that the photovoltaic power is maximized when the sunlight is sufficient, reducing the dependence on the traditional power grid. At the same time, according to the prediction results, the air conditioner can manage the energy storage equipment more effectively, store electricity when the photovoltaic power generation is excessive, and release electricity when the photovoltaic power generation is insufficient, so as to balance the supply and demand of electricity.

[0033] In order to enable the prediction model to accurately predict the photovoltaic power generation, the historical photovoltaic power generation data of the air conditioner and the local meteorological data are first collected. The photovoltaic power generation data includes daily power generation, power generation, etc.; the meteorological data includes temperature, humidity, sunshine time, cloud cover, etc. The collected data is preprocessed and cleaned, including removing outliers, filling missing values, converting data formats, etc. The data is divided into training sets and test sets for subsequent model training and verification. Feature extraction and model evaluation are then performed, specifically selecting features related to photovoltaic power generation and performing feature extraction. These features can include solar radiation intensity, temperature, humidity, etc. For each feature, standardization processing is required to make the magnitude of different features the same. Multiple prediction models are trained using the training set and standardized feature data, and the prediction performance of the model is evaluated and optimized.

[0034] like Figure 1 The flowchart of an embodiment of the method of the present invention is shown in FIG. The air conditioner control method may include: steps S110 to S140.

[0035] In step S110, after the air conditioner is equipped with the cold storage device and starts to operate, the lowest temperature of the day and the temperature difference between day and night at the location of the air conditioner and the temperature in the cold storage device are obtained.

[0036] The temperature in the cold storage device can be the medium temperature of the cold storage device. The lowest temperature of the day and the temperature difference between day and night can be obtained from the meteorological data of the location of the air conditioner. After the air conditioner starts running, the electricity generated by the photovoltaic power generation unit first ensures the normal operation of the air conditioner, and the excess electricity is stored in a suitable storage method.

[0037] In step S120, the magnitude relationship between the lowest temperature of the day and the set comfort temperature is determined.

[0038] The set comfort temperature is set by the user or is a pre-stored value for the air conditioner. The relationship between the lowest temperature of the day and the set comfort temperature can reflect whether the current indoor environment has reached a comfortable level, determine whether the air conditioner should perform cooling to adjust the indoor temperature, and then determine different energy storage methods, so that the air conditioner can effectively adjust the room temperature while reducing energy conversion losses and saving electricity.

[0039] In step S130, if the lowest temperature of the day is lower than the set comfort temperature, the storage location of the electric energy generated by the photovoltaic component is controlled according to the temperature difference between day and night and the temperature in the cold storage device.

[0040] When the lowest temperature of the day is lower than the set comfort temperature, for example, the set comfort temperature is 25°C and the lowest temperature of the day is 23°C, it is considered that the user has no cooling demand. Then, according to the temperature difference between day and night, it is determined whether the user has heating demand and selects the appropriate energy storage method, and determines whether to switch the energy storage method according to the temperature in the cold storage device to improve the energy efficiency of the air conditioner.

[0041] In some embodiments, in step S130, the specific process of controlling the storage location of the electric energy generated by the photovoltaic component according to the day and night temperature difference and the temperature in the cold storage device includes: steps S210 to S230.

[0042] Step S210, determining the magnitude relationship between the day and night temperature difference and the set temperature difference.

[0043] Step S220: If the temperature difference between day and night is less than the set temperature difference, the storage location of the electric energy generated by the photovoltaic component is controlled according to the temperature in the cold storage device.

[0044] Step S230, if the temperature difference between day and night is greater than or equal to the set temperature difference, the electric energy generated by the photovoltaic component is stored only in the battery, and then the storage position of the electric energy generated by the photovoltaic component is controlled according to the power of the battery and the temperature in the cold storage device.

[0045] The set temperature difference can be set according to the actual situation of the location of the air conditioner, which is used to determine whether the user may have a heating demand. It can be set to 15°C. When the temperature difference between day and night is less than the set temperature difference, it is considered that the user's demand for cooling is relatively high, so the cold storage device is used for energy storage first, and whether to switch to battery energy storage is selected according to the temperature of the cold storage device. When the temperature difference between day and night is greater than or equal to the set temperature difference, since the lowest temperature of the day is lower than the set comfort temperature, for example, the temperature range of the day is 10 to 27°C, the user may need cooling at a certain time and heating at a certain time, and this situation usually does not occur in summer, that is, the photovoltaic power generation will not be too much. Therefore, considering that the user needs heating, first ensure that the battery power is sufficient.

[0046] In some embodiments, in step S230, the specific process of controlling the storage location of the electric energy generated by the photovoltaic component according to the power of the battery and the temperature in the cold storage device includes: steps S310 to S350.

[0047] Step S310, determining the relationship between the power level of the battery and the set power level.

[0048] Step S320: If the power of the storage battery is less than the set power, the electric energy generated by the photovoltaic component is stored only in the storage battery.

[0049] The set power can be set to half of the maximum power of the battery. When the battery power is less than the set power, it is considered that the battery power is insufficient. At this time, in order to ensure that there is enough power to drive the air conditioner for heating, the photovoltaic power generation unit supplies power to the battery at full power to make the battery power reach above the set power.

[0050] Step S330, if the power of the battery is greater than or equal to the set power, the electric energy generated by the photovoltaic component is stored only in the cold storage device, and then the relationship between the temperature in the cold storage device and the set standard temperature is determined.

[0051] When the battery power is ≥ the set power, the energy storage mode is switched and the cold storage device is used for energy storage, so that the battery power meets the heating demand and the cold storage device's cold capacity meets the cooling demand, thereby determining the appropriate energy storage mode based on the user's heating and cooling needs, and always ensuring that the air conditioner has a high operating efficiency. In the process of using the cold storage device to store energy, it is further determined whether to end the cold storage device energy storage based on the temperature in the cold storage device and charge the battery.

[0052] Step S340: If the temperature in the cold storage device is greater than the set standard temperature, the electric energy generated by the photovoltaic component is stored only in the cold storage device.

[0053] Step S350: If the temperature in the cold storage device is less than or equal to the set standard temperature, the electric energy generated by the photovoltaic component is stored only in the battery until the battery is fully charged.

[0054] When the temperature in the cold storage device is greater than the set standard temperature, it is considered that the cold storage device is not saturated, and cold storage continues. When the temperature in the cold storage device is less than or equal to the set standard temperature, the cold storage is close to saturation, and the energy storage mode is switched to allow the photovoltaic power generation unit to continue to supply power to the battery until the battery reaches a full charge.

[0055] When the power generation unit uses the battery and the cold storage device to store cold, the power generation unit is always in full power operation. When the battery is fully charged and the cold storage device is saturated with cold, the power generation unit adjusts the light angle so that the power generation is only enough to maintain the normal operation of the air conditioning system, and the rest of the light energy is abandoned.

[0056] At step S140, if the lowest temperature of the day is greater than or equal to the set comfort temperature, the storage location of the electric energy generated by the photovoltaic component is controlled according to the temperature in the cold storage device; the storage location includes the battery and the cold storage device.

[0057] When the lowest temperature of the day is greater than or equal to the set comfort temperature, users have a demand for cooling and the air conditioner needs to convert a large amount of cooling. At this time, the cold storage device is used to store energy first, so that solar energy is directly converted into cold energy for indoor cooling, thereby reducing energy conversion losses and improving the efficiency of photovoltaic cooling.

[0058] In some embodiments, in step S220 and step S140, the specific process of controlling the storage location of the electric energy generated by the photovoltaic component according to the temperature in the cold storage device includes: judging the relationship between the temperature in the cold storage device and the set standard temperature; if the temperature in the cold storage device is greater than the set standard temperature, the electric energy generated by the photovoltaic component is only stored in the cold storage device; if the temperature in the cold storage device is less than or equal to the set standard temperature, the electric energy generated by the photovoltaic component is only stored in the battery until the battery is fully charged.

[0059] The set standard temperature is the temperature of the internal medium when the cold storage device stores enough cold. For example, the temperature range of water cold storage is 0-4℃, and the temperature range of ice cold storage is -3-0℃. When the temperature in the cold storage device is greater than the set standard temperature, it is considered that the cold storage device is not saturated. At this time, the photovoltaic power generation unit only supplies electricity to the cold storage device to drive the load to cool. When the temperature in the cold storage device is less than the set standard temperature, it is considered that the cold storage device is close to saturation. Therefore, the energy storage mode is switched to use the battery to store electricity until the battery is fully charged and the photovoltaic power generation unit no longer charges the battery. At this time, the electricity generated by the photovoltaic power generation unit can directly drive the air conditioner to operate, or it can be used for light abandonment.

[0060] In some embodiments, the process of determining whether the air conditioner is equipped with a cold storage device is also included, and the process specifically includes: before the air conditioner starts to operate, determining whether the air conditioner is equipped with the cold storage device; if the air conditioner is not equipped with the cold storage device and starts to operate, the air conditioner operates in a conventional photovoltaic air conditioning mode, and the photovoltaic power generation unit stores the electric energy generated by the photovoltaic component only in the battery while maintaining the normal operation of the air conditioner until the battery is fully charged.

[0061] Figure 3 FIG. 1 is a flow chart of a control method of an energy storage air conditioner according to the present invention, as shown in FIG. Figure 3 As shown, the method includes:

[0062] Step 1: In the photovoltaic air conditioning system, use the prediction model to predict the power generation of the system. After completing the power generation prediction, determine whether the cold storage device is installed in the system. If there is no cold storage device connected, the photovoltaic air conditioning system will prioritize charging the energy storage unit to 100% while maintaining the normal operation of the system, and then the power generation unit will abandon light and only maintain the normal operation of the system. If a cold storage device is connected to the system, proceed to step 2.

[0063] Step 2, determine whether the lowest temperature of the day is greater than the user's comfortable temperature. If the lowest temperature of the day is ≤ the user's comfortable temperature, proceed to step 3. If the lowest temperature of the day is greater than the user's comfortable temperature, further determine whether the temperature in the cold storage device has reached the preset temperature. If the temperature in the cold storage device has not reached the preset temperature, the photovoltaic unit will run at full power to drive the cold storage device to store cold; if the temperature in the cold storage device reaches the preset temperature, the photovoltaic unit will run at full power to charge the energy storage unit until the energy storage unit is fully charged.

[0064] Step 3, determine whether the temperature difference between day and night in the location of the air conditioner is ≥15°C. If the temperature difference between day and night is <15°C, execute step 2. If the temperature difference between day and night is ≥15°C, further determine whether the power of the energy storage unit has reached 50%. If the power of the energy storage unit has not reached 50%, the photovoltaic unit charges the energy storage unit at full power. If the power of the energy storage unit has reached 50%, the photovoltaic unit drives the cold storage device to store cold, and determines whether the temperature in the cold storage device has reached the preset temperature. If the temperature in the cold storage device has not reached the preset temperature, the photovoltaic unit runs at full power and drives the cold storage device to store cold; if the temperature in the cold storage device reaches the preset temperature, the photovoltaic unit runs at full power to charge the energy storage unit until the energy storage unit is fully charged.

[0065] By adding a cold storage device to the photovoltaic air conditioner and selecting the appropriate energy storage method according to meteorological data, the components reduce the loss in the energy conversion process and the number of battery charge and discharge times, that is, the battery usage is reduced, the production cost of the air conditioner is reduced, the harm of environmental pollution is reduced, and the air conditioner’s dependence on weather conditions and batteries during the peak period of electricity consumption in summer is reduced.

[0066] By adopting the technical solution of this embodiment, a cold storage device is added to the photovoltaic air conditioner with a battery; after the air conditioner starts to operate, if the lowest temperature of the day is lower than the set comfortable temperature, the storage position of the electric energy generated by the photovoltaic component is controlled according to the temperature difference between day and night and the temperature in the cold storage device; if the lowest temperature of the day is greater than or equal to the set comfortable temperature, the storage position of the electric energy generated by the photovoltaic component is controlled according to the temperature in the cold storage device. Thus, by adding a cold storage device that can convert electric energy into cold for storage in the photovoltaic air conditioner, the battery or the cold storage device is selected for energy storage according to the lowest temperature of the day and the temperature difference between day and night, thereby simplifying the energy transmission path, reducing the loss in the energy conversion process, and improving energy utilization.

[0067] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for an air conditioner is also provided. The air conditioner has a photovoltaic component and a storage battery; the electric energy generated by the photovoltaic component can be stored in the storage battery; the air conditioner can be additionally provided with a cold storage device; the electric energy generated by the photovoltaic component can also be stored in the cold storage device in the form of cold energy.

After the cold storage device is connected to the air conditioning system, the electric energy generated by the photovoltaic power generation unit can also drive the cold storage device to generate cold, thereby storing the electric energy in the form of cold.

[0069] The medium in the cold storage device can be set to water. The cold storage device can also select other media that are not prone to phase change or have a larger phase change temperature range as the cold storage medium to reduce the pressure exerted by the medium on the cold storage device during cold storage. The cold stored in the cold storage device can be directly used for refrigeration, thereby reducing the loss of energy conversion and improving the operating efficiency of the photovoltaic air conditioner.

[0070] The prediction unit can use the prediction model to predict the amount of electricity generated by the photovoltaic power generation unit. According to the prediction results, the power resources can be accurately dispatched to ensure that the photovoltaic power is maximized when the sunlight is sufficient, reducing the dependence on the traditional power grid. At the same time, according to the prediction results, the air conditioner can manage the energy storage equipment more effectively, store electricity when the photovoltaic power generation is excessive, and release electricity when the photovoltaic power generation is insufficient, so as to balance the supply and demand of electricity.

Feature extraction and model evaluation are then performed, specifically selecting features related to photovoltaic power generation and performing feature extraction. These features can include solar radiation intensity, temperature, humidity, etc. For each feature, standardization processing is required to make the magnitude of different features the same. Multiple prediction models are trained using the training set and standardized feature data, and the prediction performance of the model is evaluated and optimized.

[0072] See also Figure 2 The schematic diagram of the structure of an embodiment of the device of the present invention is shown. The control device of the air conditioner may include: an acquisition unit 102 and a control unit 104.

[0073] The acquisition unit 102 is configured to acquire the lowest temperature of the day and the temperature difference between day and night at the location of the air conditioner and the temperature in the cold storage device after the air conditioner is equipped with the cold storage device and starts to operate. The specific functions and processing of the acquisition unit 102 refer to step S110.

[0074] The temperature in the cold storage device can be the medium temperature of the cold storage device. The lowest temperature of the day and the temperature difference between day and night can be obtained from the meteorological data of the location of the air conditioner. After the air conditioner starts running, the electricity generated by the photovoltaic power generation unit first ensures the normal operation of the air conditioner, and the excess electricity is stored in a suitable storage method.

[0075] The control unit 104 is configured to determine the magnitude relationship between the lowest temperature of the day and the set comfort temperature. The specific functions and processing of the control unit 104 refer to step S120.

[0076] The set comfort temperature is set by the user or is a pre-stored value for the air conditioner. The relationship between the lowest temperature of the day and the set comfort temperature can reflect whether the current indoor environment has reached a comfortable level, determine whether the air conditioner should perform cooling to adjust the indoor temperature, and then determine different energy storage methods, so that the air conditioner can effectively adjust the room temperature while reducing energy conversion losses and saving electricity.

[0077] The control unit 104 is further configured to control the storage location of the electric energy generated by the photovoltaic component according to the day-night temperature difference and the temperature in the cold storage device if the lowest temperature of the day is lower than the set comfort temperature. The specific functions and processing of the control unit 104 refer to step S130.

[0078] When the lowest temperature of the day is lower than the set comfort temperature, for example, the set comfort temperature is 25°C and the lowest temperature of the day is 23°C, it is considered that the user has no cooling demand. Then, according to the temperature difference between day and night, it is determined whether the user has heating demand and selects the appropriate energy storage method, and determines whether to switch the energy storage method according to the temperature in the cold storage device to improve the energy efficiency of the air conditioner.

[0079] In some embodiments, the control unit 104 controls the storage location of the electric energy generated by the photovoltaic component according to the day and night temperature difference and the temperature in the cold storage device, including:

[0080] The control unit 104 is further configured to determine the magnitude relationship between the day and night temperature difference and the set temperature difference. The specific functions and processing of the control unit 104 refer to step S210.

[0081] The control unit 104 is further configured to control the storage location of the electric energy generated by the photovoltaic component according to the temperature in the cold storage device if the day and night temperature difference is less than the set temperature difference. The specific functions and processing of the control unit 104 refer to step S220.

[0082] The control unit 104 is further configured to store the electric energy generated by the photovoltaic component only in the battery if the temperature difference between day and night is greater than or equal to the set temperature difference, and then control the storage location of the electric energy generated by the photovoltaic component according to the power of the battery and the temperature in the cold storage device. The specific functions and processing of the control unit 104 refer to step S230.

[0083] The set temperature difference can be set according to the actual situation of the location of the air conditioner, which is used to determine whether the user may have a heating demand. It can be set to 15°C. When the temperature difference between day and night is less than the set temperature difference, it is considered that the user's demand for cooling is relatively high, so the cold storage device is used for energy storage first, and whether to switch to battery energy storage is selected according to the temperature of the cold storage device. When the temperature difference between day and night is greater than or equal to the set temperature difference, since the lowest temperature of the day is lower than the set comfort temperature, for example, the temperature range of the day is 10 to 27°C, the user may need cooling at a certain time and heating at a certain time, and this situation usually does not occur in summer, that is, the photovoltaic power generation will not be too much. Therefore, considering that the user needs heating, first ensure that the battery power is sufficient.

[0084] In some embodiments, the control unit 104 controls the storage location of the electric energy generated by the photovoltaic component according to the power of the battery and the temperature in the cold storage device, including:

[0085] The control unit 104 is further configured to determine the relationship between the power level of the battery and the set power level. The specific functions and processing of the control unit 104 refer to step S310.

[0086] The control unit 104 is further configured to store the electric energy generated by the photovoltaic component only in the battery if the electric power of the battery is less than the set electric power. The specific functions and processing of the control unit 104 refer to step S320.

[0087] The set power can be set to half of the maximum power of the battery. When the battery power is less than the set power, it is considered that the battery power is insufficient. At this time, in order to ensure that there is enough power to drive the air conditioner for heating, the photovoltaic power generation unit supplies power to the battery at full power to make the battery power reach above the set power.

[0088] The control unit 104 is further configured to store the electric energy generated by the photovoltaic component only in the cold storage device if the electric power of the storage battery is greater than or equal to the set electric power, and then determine the relationship between the temperature in the cold storage device and the set standard temperature. The specific functions and processing of the control unit 104 refer to step S330.

[0089] When the battery power is ≥ the set power, the energy storage mode is switched and the cold storage device is used for energy storage, so that the battery power meets the heating demand and the cold storage device's cold capacity meets the cooling demand, thereby determining the appropriate energy storage mode based on the user's heating and cooling needs, and always ensuring that the air conditioner has a high operating efficiency. In the process of using the cold storage device to store energy, it is further determined whether to end the cold storage device energy storage based on the temperature in the cold storage device and charge the battery.

[0090] The control unit 104 is further configured to store the electric energy generated by the photovoltaic component only in the cold storage device if the temperature in the cold storage device is greater than a set standard temperature. The specific functions and processing of the control unit 104 refer to step S340.

[0091] The control unit 104 is further configured to store the electric energy generated by the photovoltaic component only in the battery until the battery is fully charged if the temperature in the cold storage device is less than or equal to the set standard temperature. The specific functions and processing of the control unit 104 refer to step S350.

[0092] When the temperature in the cold storage device is greater than the set standard temperature, it is considered that the cold storage device is not saturated, and cold storage continues. When the temperature in the cold storage device is less than or equal to the set standard temperature, the cold storage is close to saturation, and the energy storage mode is switched to allow the photovoltaic power generation unit to continue to supply power to the battery until the battery reaches a full charge.

[0093] When the power generation unit uses the battery and the cold storage device to store cold, the power generation unit is always in full power operation. When the battery is fully charged and the cold storage device is saturated with cold, the power generation unit adjusts the light angle so that the power generation is only enough to maintain the normal operation of the air conditioning system, and the rest of the light energy is abandoned.

[0094] The control unit 104 is further configured to control the storage location of the electric energy generated by the photovoltaic component according to the temperature in the cold storage device if the lowest temperature of the day is greater than or equal to the set comfort temperature; the storage location includes the battery and the cold storage device. The specific functions and processing of the control unit 104 refer to step S140.

[0095] When the lowest temperature of the day is greater than or equal to the set comfort temperature, users have a demand for cooling and the air conditioner needs to convert a large amount of cooling. At this time, the cold storage device is used to store energy first, so that solar energy is directly converted into cold energy for indoor cooling, thereby reducing energy conversion losses and improving the efficiency of photovoltaic cooling.

[0096] In some embodiments, the control unit 104 controls the storage location of the electric energy generated by the photovoltaic component according to the temperature in the cold storage device, including: judging the relationship between the temperature in the cold storage device and the set standard temperature; if the temperature in the cold storage device is greater than the set standard temperature, the electric energy generated by the photovoltaic component is only stored in the cold storage device; if the temperature in the cold storage device is less than or equal to the set standard temperature, the electric energy generated by the photovoltaic component is only stored in the battery until the battery is fully charged.

[0097] The set standard temperature is the temperature of the internal medium when the cold storage device stores enough cold. For example, the temperature range of water cold storage is 0-4℃, and the temperature range of ice cold storage is -3-0℃. When the temperature in the cold storage device is greater than the set standard temperature, it is considered that the cold storage device is not saturated. At this time, the photovoltaic power generation unit only supplies electricity to the cold storage device to drive the load to cool. When the temperature in the cold storage device is less than the set standard temperature, it is considered that the cold storage device is close to saturation. Therefore, the energy storage mode is switched to use the battery to store electricity until the battery is fully charged and the photovoltaic power generation unit no longer charges the battery. At this time, the electricity generated by the photovoltaic power generation unit can directly drive the air conditioner to operate, or it can be used for light abandonment.

[0098] In some embodiments, the control unit 104 is further configured to determine whether the air conditioner is equipped with a cold storage device, including: before the air conditioner starts to run, determining whether the air conditioner is equipped with the cold storage device; if the air conditioner is not equipped with the cold storage device and starts to run, the air conditioner operates in a conventional photovoltaic air conditioning mode, and the photovoltaic power generation unit stores the electric energy generated by the photovoltaic component only in the battery while maintaining the normal operation of the air conditioner until the battery is fully charged.

[0099] Figure 3 FIG. 1 is a flow chart of a control method of an energy storage air conditioner according to the present invention, as shown in FIG. Figure 3 As shown, the method includes:

[0100] Step 1: In the photovoltaic air conditioning system, use the prediction model to predict the power generation of the system. After completing the power generation prediction, determine whether the cold storage device is installed in the system. If there is no cold storage device connected, the photovoltaic air conditioning system will prioritize charging the energy storage unit to 100% while maintaining the normal operation of the system, and then the power generation unit will abandon light and only maintain the normal operation of the system. If a cold storage device is connected to the system, proceed to step 2.

[0101] Step 2, determine whether the lowest temperature of the day is greater than the user's comfortable temperature. If the lowest temperature of the day is ≤ the user's comfortable temperature, proceed to step 3. If the lowest temperature of the day is greater than the user's comfortable temperature, further determine whether the temperature in the cold storage device has reached the preset temperature. If the temperature in the cold storage device has not reached the preset temperature, the photovoltaic unit will run at full power to drive the cold storage device to store cold; if the temperature in the cold storage device reaches the preset temperature, the photovoltaic unit will run at full power to charge the energy storage unit until the energy storage unit is fully charged.

[0102] Step 3, determine whether the temperature difference between day and night in the location of the air conditioner is ≥15°C. If the temperature difference between day and night is <15°C, execute step 2. If the temperature difference between day and night is ≥15°C, further determine whether the power of the energy storage unit has reached 50%. If the power of the energy storage unit has not reached 50%, the photovoltaic unit charges the energy storage unit at full power. If the power of the energy storage unit has reached 50%, the photovoltaic unit drives the cold storage device to store cold, and determines whether the temperature in the cold storage device has reached the preset temperature. If the temperature in the cold storage device has not reached the preset temperature, the photovoltaic unit runs at full power and drives the cold storage device to store cold; if the temperature in the cold storage device reaches the preset temperature, the photovoltaic unit runs at full power to charge the energy storage unit until the energy storage unit is fully charged.
