In order to adjust the pre-stored power of the battery module 1 to supply power for the heat pump and / or the fresh air conditioner, and / or, to provide a structural basis for adjusting the pre-adjustment temperature of the buffer water tank 22.

[0055] In combination Figure 2 As shown in the embodiment of the present disclosure, an energy-saving method for an air system is provided, which comprises the following steps:

[0056] In S201, the air system determines the predicted next-day weather data and the predicted next-day indoor user life data.

[0057] In S202, the air system adjusts the pre-stored power of the battery module to supply power for the heat pump and / or the fresh air conditioner, and / or, adjusts the pre-adjustment temperature of the buffer water tank in the previous valley power period of the peak power period according to the predicted next-day weather data and the predicted next-day indoor user life data.

[0058] The energy-saving method for an air system provided by the embodiment of the present disclosure can adjust the pre-stored power of the battery module to supply power for the heat pump and / or the fresh air conditioner, and / or, adjust the pre-adjustment temperature of the buffer water tank in the previous valley power period of the peak power period according to the predicted next-day weather data and the predicted next-day indoor user life data, so as to avoid adjusting the temperature of the buffer water tank and the heating pipe by the high-cost electricity price in the peak power period. In this way, the influence of the floor heating on the indoor air environment in the air system is considered, and the energy waste of the air system is reduced.

[0059] Optionally, the air system adjusts the pre-stored power of the battery module to supply power for the heat pump and / or the fresh air conditioner, and / or, adjusts the pre-adjustment temperature of the buffer water tank according to the predicted next-day weather data and the predicted next-day indoor user life data, which comprises: the air system determines the power consumption load of the air system according to the predicted next-day indoor user life data. The air system adjusts the pre-stored power of the battery module to supply power for the heat pump and / or the fresh air conditioner, and / or, adjusts the pre-adjustment temperature of the buffer water tank according to the power consumption load of the air system and the predicted next-day weather data.

[0060] In this way, in the previous valley power period of the peak power period, the power consumption load is predicted according to the predicted next-day weather data, and then the pre-stored power of the battery module is adjusted to supply power for the heat pump and / or the fresh air conditioner, and / or, the pre-adjustment temperature of the buffer water tank is adjusted to avoid adjusting the temperature of the buffer water tank and the heating pipe by the high-cost electricity price in the peak power period, so as to reduce the energy waste of the air system.

[0061] Optionally, the predicted next-day indoor user life data comprises: a next-day work and rest schedule, a next-day indoor user quantity, a next-day indoor user identity, and a next-day user going-out and staying-at-home habit. The air system determines the power consumption load of the air system according to the predicted next-day indoor user life data, comprising: in the case that the next-day work and rest schedule is a workday, the air system determines the power consumption load of the air system to be a first load or a second load according to the next-day indoor user quantity and / or the next-day indoor user identity. Or, in the case that the next-day work and rest schedule is a rest day, the air system determines the power consumption load of the air system to be a third load, a fourth load, or a fifth load according to the next-day user going-out and staying-at-home habit; wherein the third load, the fourth load, and the fifth load are all greater than the first load and the second load.

[0062] In this way, if the next day is a workday, there are fewer indoor users, and a smaller power consumption load, such as the first load or the second load, is often needed. If the next day is a rest day, there are more indoor users than on a workday, and a larger power consumption load, such as the third load, the fourth load, or the fifth load, is often needed. In this way, it is beneficial to more accurately determine the power consumption load, so that the pre-stored power of the battery module and the pre-adjusted temperature of the buffer water tank are more accurate.

[0063] Optionally, the air system determines the power consumption load of the air system to be the first load or the second load according to the next-day indoor user quantity and / or the next-day indoor user identity, comprising: in the case that the next-day indoor user quantity is zero, the air system determines the power consumption load of the air system to be the first load. Or, in the case that the next-day indoor user quantity is greater than zero and the next-day indoor user identity is an old person and / or a child, the air system determines the power consumption load of the air system to be the second load. Wherein the first load is smaller than the second load.

[0064] Specifically, the ratio of the first load to the rated load is in the range of [0, 20%], and the ratio of the second load to the rated load is in the range of (20%, 40%].

[0065] In this way, if the next day is a workday and there is no one in the room, the smallest power consumption load is needed. If the next day is a workday and there is only an old person and / or a child in the room, a smaller power consumption load is needed. In this way, it is beneficial to more accurately determine the power consumption load, so that the pre-stored power of the battery module and the pre-adjusted temperature of the buffer water tank are more accurate, and it is beneficial to more accurately reduce the energy consumption of the air system.

[0066] Optionally, the air system determines the power consumption load of the air system as a third load, a fourth load or a fifth load according to the next day user's outing home habit, including: the air system determines the power consumption load of the air system as the third load in the case that the next day user's outing home habit is outing for fun. Or, the air system determines the power consumption load of the air system as the fourth load in the case that the next day user's outing home habit is home resting. Or, the air system determines the power consumption load of the air system as the fifth load in the case that the next day user's outing home habit is home gathering. Wherein, the third load is less than the fourth load, and the fourth load is less than the fifth load.

[0067] Specifically, the ratio of the third load to the rated load is in the range of (40%, 60%], the ratio of the fourth load to the rated load is in the range of (60%, 80%], and the ratio of the fifth load to the rated load is in the range of (80%, 100%].

[0068] In this way, if the next day is a weekday and the user habit is outing for fun, the air system needs a small load higher than the second load. If the next day is a weekday and the user habit is home resting, the air system needs a larger load. If the next day is a weekday and the user habit is home gathering, the air system needs the largest load. In this way, it is beneficial to more accurately determine the power consumption load, so that the pre-stored power of the battery module and the pre-adjusted temperature of the buffer water tank are more accurate, and it is beneficial to more accurately reduce the energy consumption of the air system.

[0069] Optionally, the air system adjusts the pre-stored power of the battery module to supply power to the heat pump and / or fresh air conditioner and / or adjusts the pre-adjusted temperature of the buffer water tank according to the power consumption load of the air system and the predicted next day weather data, including: the air system determines the next day predicted photovoltaic power generation according to the predicted next day weather data. The air system adjusts the pre-stored power of the battery module to supply power to the heat pump and / or fresh air conditioner and / or adjusts the pre-adjusted temperature of the buffer water tank according to the power consumption load of the air system and the next day predicted photovoltaic power generation.

[0070] In this way, the predicted next day weather data can predict the next day predicted photovoltaic power generation, and according to the size of the power consumption load and the next day predicted photovoltaic power generation, it is beneficial to more accurately adjust the pre-stored power of the battery module and the pre-adjusted temperature of the buffer water tank, and it is beneficial to more accurately reduce the energy consumption of the air system.

[0071] Optionally, the air system determines the next-day predicted photovoltaic power generation according to the predicted next-day weather data, including: the air system determines the next-day predicted photovoltaic power generation as a first power generation when the predicted next-day weather data is sunny. Or, the air system determines the next-day predicted photovoltaic power generation as a second power generation when the predicted next-day weather data is cloudy. Or, the air system determines the next-day predicted photovoltaic power generation as zero when the predicted next-day weather data is rainy. Wherein, the first power generation is greater than the second power generation, and the second power generation is greater than zero.

[0072] In this way, the next-day predicted photovoltaic power generation corresponding to the predicted next-day weather of sunny, cloudy, and rainy is successively from large to small, which is conducive to more accurately determining the next-day predicted photovoltaic power generation, more accurately adjusting the pre-storage power of the battery module and the pre-adjustment temperature of the buffer water tank, and reducing the energy consumption of the air system more accurately.

[0073] Optionally, the air system adjusts the pre-storage power of the battery module to supply power to the heat pump and / or fresh air conditioner and / or adjusts the pre-adjustment temperature of the buffer water tank according to the power consumption of the air system and the next-day predicted photovoltaic power generation, including: the air system calculates the difference between the power consumption of the air system and the next-day predicted photovoltaic power generation to obtain a power difference. The air system adjusts the pre-storage power of the battery module to supply power to the heat pump and / or fresh air conditioner and / or adjusts the pre-adjustment temperature of the buffer water tank according to the power difference.

[0074] In this way, the power difference between the power consumption of the air system and the next-day predicted photovoltaic power generation is calculated first, and then the pre-storage power of the battery module and the pre-adjustment temperature of the buffer water tank are adjusted according to the power difference when the next-day predicted photovoltaic power generation is insufficient, which is conducive to more accurately reducing the energy consumption of the air system.

[0075] Optionally, the air system adjusts the pre-storage power of the battery module to supply power to the heat pump and / or fresh air conditioner and / or adjusts the pre-adjustment temperature of the buffer water tank according to the power difference, including: the air system adjusts the pre-storage power of the battery module to supply power to the heat pump and / or fresh air conditioner when the power difference is less than or equal to the rated storage power of the battery module. Or, the air system adjusts the pre-storage power of the battery module to supply power to the heat pump and / or fresh air conditioner and adjusts the pre-adjustment temperature of the buffer water tank when the power difference is greater than the rated storage power of the battery module.

[0076] In this way, if the battery module can provide the power greater than or equal to the power difference, only the pre-stored power of the battery module needs to be adjusted in the valley electricity period before the peak electricity period to supply power to the heat pump and / or fresh air conditioner, which is conducive to reducing the power consumption of the air system and reducing the energy consumption of the air system. If the battery module can provide the power less than the power difference, the pre-stored power of the battery module needs to be adjusted in the valley electricity period before the peak electricity period to supply power to the heat pump and / or fresh air conditioner, while the pre-adjusted temperature of the buffer water tank also needs to be adjusted to reduce the energy consumption of the air system.

[0077] Optionally, the air system adjusts the pre-stored power of the battery module to supply power to the heat pump and / or fresh air conditioner, comprising: the air system charges the battery module according to the power difference in the valley electricity period to make the pre-stored power equal to the power difference, so that the battery module supplies power to the heat pump and / or fresh air conditioner in the case of insufficient photovoltaic power generation.

[0078] In this way, if the battery module can provide the power greater than or equal to the power difference, only the pre-stored power of the battery module needs to be adjusted in the valley electricity period before the peak electricity period to supply power to the heat pump and / or fresh air conditioner, which is conducive to reducing the power consumption of the air system and reducing the energy consumption of the air system. If the battery module can provide the power less than the power difference, the pre-stored power of the battery module needs to be adjusted in the valley electricity period before the peak electricity period to supply power to the heat pump and / or fresh air conditioner, while the pre-adjusted temperature of the buffer water tank also needs to be adjusted to reduce the energy consumption of the air system.

[0079] Optionally, the air system adjusts the pre-adjusted temperature of the buffer water tank, comprising: the air system adjusts the pre-adjusted temperature of the buffer water tank to a first temperature to control the water in the buffer water tank to mix with the water in the heating pipe in the peak electricity period of the next day. The first temperature is greater than the second temperature, the second temperature is greater than the third temperature, the second temperature is the water temperature set for heating, and the third temperature is the water temperature in the heating pipe.

[0080] For example, the second temperature is 35℃, the water in the buffer water tank is heated to 60℃ in advance in the valley electricity period, and the water in the buffer water tank is mixed with the water in the heating pipe in the peak electricity period of the next day, so that the water in the heating pipe is mixed from less than 30℃ to the required 35℃ water.

[0081] In this way, if the battery module can provide insufficient power to cover the power difference, the pre-stored power of the battery module is adjusted in the valley electricity period before the peak electricity period, and the pre-adjusted temperature of the buffer water tank is increased to a higher first temperature in the valley electricity period while the buffer water tank supplies power to the heat pump and / or fresh air conditioner when photovoltaic power generation is insufficient the next day, and the water in the buffer water tank is mixed with the water in the heating pipe at a lower third temperature to a second temperature set for heating in the peak electricity period the next day, so as to make up for the problem of insufficient power of the battery module, and to reduce the power cost and the energy consumption of the air system.

[0082] Optionally, the air system adjusts the pre-adjusted temperature of the buffer water tank to the first temperature, so that after the water in the buffer water tank is mixed with the water in the heating pipe, the air system directly supplies power to the heat pump and / or fresh air conditioner when the mixing temperature of the water in the buffer water tank and the water in the heating pipe is less than the second temperature.

[0083] In this way, if the water in the buffer water tank and the water in the heating pipe cannot reach the second temperature set for heating after mixing, the heat pump and / or fresh air conditioner is directly powered by the mains. In this way, the problem of insufficient water in the buffer water tank is solved, and the power cost and the energy consumption of the air system are reduced.
