Technical Field

[0001] The present application relates to the field of energy storage technology, and in particular to a control method, device, control equipment, and storage medium for an energy storage valve air conditioning system. Background Art

[0002] High-pressure energy storage valves have the advantages of high modularity and high operational reliability. They are composed of power modules and battery modules. During operation, the power modules and battery modules will generate heat, and the energy storage valve has a high operating voltage level and high temperature. Therefore, it is necessary to set up an energy storage valve air conditioning system to adjust the ambient temperature and humidity of the energy storage valve.

[0003] However, the current energy storage valve air conditioning system consumes a lot of electricity. Summary of the invention

[0004] In view of the above problems, the present application provides a control method, device, control equipment and storage medium for an energy storage valve air conditioning system, which can solve the problem of high power consumption of the energy storage valve air conditioning system in the related art.

[0005] In a first aspect, the present application provides a control method for an energy storage valve air conditioning system. The method comprises:

[0006] Obtaining an operation mode of an energy storage valve in an energy storage valve system;

[0007] The working mode of the energy storage valve air conditioning system is controlled according to a preset relationship between the operation mode of the energy storage valve and the working mode of the energy storage valve air conditioning system.

[0008] In the technical solution of the embodiment of the present application, the operating mode of the energy storage valve in the energy storage valve system is obtained, and the operating mode of the energy storage valve air conditioning system is controlled according to the preset relationship between the operating mode of the energy storage valve and the operating mode of the energy storage valve air conditioning system. Since the operating mode of the energy storage valve air conditioning system is controlled according to the preset relationship between the operating mode of the energy storage valve and the operating mode of the energy storage valve air conditioning system, the operating mode of the energy storage valve air conditioning system can be matched with the operating mode of the energy storage valve, so that the circulating air volume of the energy storage valve air conditioning system can adapt to the heat generated by the energy storage valve during operation, thereby saving the power consumption of the energy storage valve air conditioning system and improving the operating efficiency of the energy storage valve air conditioning system.

[0009] In some embodiments, according to a preset relationship between the operation mode of the energy storage valve and the operation mode of the energy storage valve air conditioning system, controlling the operation mode of the energy storage valve air conditioning system includes:

[0010] When it is detected that the energy storage valve in the energy storage valve system switches from the first operation mode to the second operation mode, determining a target operation mode corresponding to the second operation mode according to a preset relationship;

[0011] The fan near the inlet of the energy storage valve valve hall in the energy storage valve air conditioning system is controlled to operate in a target working mode.

[0012] In the technical solution of the embodiment of the present application, when it is detected that the energy storage valve in the energy storage valve system switches from the first operating mode to the second operating mode, the target operating mode corresponding to the second operating mode is determined according to the preset relationship, and the fan near the inlet of the energy storage valve valve hall in the energy storage valve air-conditioning system is controlled to operate in the target operating mode. It can be seen that in the embodiment of the present application, by adjusting the operating mode of the fan near the inlet of the energy storage valve valve hall to the target operating mode matching the operating mode of the energy storage valve according to the different operating modes of the energy storage valve in the energy storage valve system, the circulating air volume of the energy storage valve air-conditioning system can adapt to the heat generated by the energy storage valve during operation, thereby saving the power consumption of the energy storage valve air-conditioning system and improving the operating efficiency of the energy storage valve air-conditioning system. In addition, the circulating air volume of the fan in different modes meets the anti-condensation and micro-positive pressure requirements of the energy storage valve, which can reduce the power consumption of the energy storage valve air-conditioning system while ensuring the long-term reliable operation of the energy storage valve.

[0013] In some embodiments, determining the target operating mode corresponding to the second operating mode according to the preset relationship includes:

[0014] If the first operation mode is a zero power operation mode and the second operation mode is a peak shaving and valley filling operation mode or a frequency modulation operation mode, the rated operation mode of the energy storage valve air conditioning system is used as the target operation mode according to a preset relationship.

[0015] In the technical solution of the embodiment of the present application, when the first operation mode is the zero power operation mode and the second operation mode is the peak shaving and valley filling operation mode or the frequency modulation operation mode, the rated operation mode of the energy storage valve air conditioning system is used as the target operation mode according to the preset relationship. When the energy storage valve is switched to the peak shaving and valley filling operation mode or the frequency modulation operation mode with relatively large heat generation, the rated operation mode of the energy storage valve air conditioning system is used as the target operation mode, and then the energy storage valve air conditioning system is controlled to operate in the rated operation mode, so that the operation mode of the energy storage valve air conditioning system matches the operation mode of the energy storage valve, and the air volume required when the energy storage valve operates in the peak shaving and valley filling operation mode or the frequency modulation operation mode is met.

[0016] In some embodiments, controlling a fan near an inlet of a valve hall of an energy storage valve in an energy storage valve air conditioning system to operate in a target operating mode includes:

[0017] A first control instruction is generated according to the rated working mode, and the first control instruction is sent to the fan, wherein the first control instruction is used to instruct the fan to switch from the low-frequency working mode to the rated working mode.

[0018] In the technical solution of the embodiment of the present application, when the first operating mode is the zero-power operating mode and the second operating mode is the peak-shaving and valley-filling operating mode or the frequency modulation operating mode, the first control device takes the rated operating mode as the target operating mode, and then generates a first control instruction according to the rated operating mode, and sends the first control instruction to the fan to realize the switching of the fan from the low-frequency operating mode to the rated operating mode, so that the operating mode of the energy storage valve air-conditioning system matches the operating mode of the energy storage valve, and meets the air volume required when the energy storage valve operates in the peak-shaving and valley-filling operating mode and the frequency modulation operating mode.

[0019] In some embodiments, determining the target operating mode corresponding to the second operating mode according to the preset relationship includes:

[0020] If the first operating mode is a peak shaving and valley filling operating mode or a frequency modulation operating mode, and the second operating mode is a zero power operating mode, the low frequency operating mode of the energy storage valve air conditioning system is used as the target operating mode according to a preset relationship.

[0021] In the technical solution of the embodiment of the present application, if the first operating mode is a peak shaving and valley filling operating mode or a frequency modulation operating mode, and the second operating mode is a zero power operating mode, then according to the preset relationship, the low frequency operating mode of the energy storage valve air conditioning system is used as the target operating mode. When the energy storage valve is switched to the zero power operating mode with relatively small heat generation, the low frequency operating mode of the energy storage valve air conditioning system is used as the target operating mode, and then the energy storage valve air conditioning system is controlled to operate in the low frequency operating mode, so that the operating mode of the energy storage valve air conditioning system matches the operating mode of the energy storage valve, and the required air volume is met when the energy storage valve operates in the zero power operating mode. In addition, the circulating air volume of the second fan operating in the low frequency operating mode meets the anti-condensation and micro-positive pressure requirements of the energy storage valve, which can reduce the power consumption of the energy storage valve air conditioning system while ensuring the long-term reliable operation of the energy storage valve.

[0022] In some embodiments, controlling a fan near an inlet of a valve hall of an energy storage valve in an energy storage valve air conditioning system to operate in a target operating mode includes:

[0023] If the first operation mode is the peak shaving and valley filling operation mode, a second control instruction is generated according to the low-frequency operation mode, and the second control instruction is sent to the wind turbine, wherein the second control instruction is used to instruct the wind turbine to switch from the rated operation mode to the low-frequency operation mode after a delay of a first preset time;

[0024] If the first operating mode is the frequency modulation operating mode, a third control instruction is generated according to the low-frequency operating mode, and the third control instruction is sent to the fan, wherein the third control instruction is used to instruct the fan to switch from the rated operating mode to the low-frequency operating mode after a delay of a second preset time; the first preset time is greater than the second preset time.

[0025] In the technical solution of the embodiment of the present application, it is possible to use the low-frequency working mode of the energy storage valve air-conditioning system as the target working mode when the energy storage valve switches to the zero-power operating mode with relatively small heat generation, and then control the energy storage valve air-conditioning system to operate in the low-frequency working mode, so that the working mode of the energy storage valve air-conditioning system matches the operating mode of the energy storage valve, and the air volume required when the energy storage valve operates in the zero-power operating mode is met. In addition, the circulating air volume of the second fan operating in the low-frequency working mode meets the anti-condensation and micro-positive pressure requirements of the energy storage valve, while reducing the power consumption of the energy storage valve air-conditioning system, it can also ensure the long-term reliable operation of the energy storage valve. In addition, the second preset time length is less than the first preset time length, so as to achieve the delay and the time length required by the actual situation, so that the second fan enters the low-frequency working mode as early as possible, thereby further saving the power consumption of the energy storage valve air-conditioning system.

[0026] In some embodiments, determining the target operating mode corresponding to the second operating mode according to the preset relationship includes:

[0027] If the first operation mode is the peak shaving and valley filling operation mode, and the second operation mode is the frequency modulation operation mode, then according to the preset relationship, the rated operation mode of the energy storage valve air conditioning system is used as the target operation mode.

[0028] In the technical solution of the embodiment of the present application, when the first operating mode is the peak shaving and valley filling operating mode and the second operating mode is the frequency modulation operating mode, the rated operating mode of the energy storage valve air-conditioning system is used as the target operating mode according to the preset relationship, so that the fan near the inlet of the energy storage valve valve hall in the energy storage valve air-conditioning system is maintained in the rated operating mode, and the operating mode of the second fan in the energy storage valve air-conditioning system is matched with the operating mode of the energy storage valve system.

[0029] In some embodiments, determining the target operating mode corresponding to the second operating mode according to the preset relationship includes:

[0030] If the first operation mode is the frequency modulation operation mode and the second operation mode is the peak shaving and valley filling operation mode, then according to the preset relationship, the rated operation mode of the energy storage valve air conditioning system is used as the target operation mode.

[0032] A fourth control instruction is generated according to the rated working mode, and the fourth control instruction is sent to the wind turbine, wherein the fourth control instruction is used to instruct the wind turbine to maintain the rated working mode.

[0033] In the technical solution of the embodiment of the present application, when the first operating mode is the frequency modulation operating mode and the second operating mode is the peak shaving and valley filling operating mode, the rated operating mode of the energy storage valve air-conditioning system is used as the target operating mode according to the preset relationship, so that the fan near the inlet of the energy storage valve valve hall in the energy storage valve air-conditioning system is maintained in the rated operating mode, and the operating mode of the second fan in the energy storage valve air-conditioning system is matched with the operating mode of the energy storage valve system.

[0056] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0058] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0059] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0060] The control method, device, equipment and storage medium of the energy storage valve air-conditioning system provided in the embodiments of the present application can be applied to the control application scenario of the high-pressure energy storage valve air-conditioning system; of course, it can also be applied to other application scenarios.

[0061] High-pressure energy storage valves have the advantages of high modularity and high operational reliability. They are composed of power modules and battery modules. During operation, the power modules and battery modules will generate heat, and the energy storage valve has a high operating voltage level and high temperature. Therefore, it is necessary to set up an energy storage valve air conditioning system to adjust the ambient temperature and humidity of the energy storage valve.

[0062] The power module and battery module of the current new high-pressure energy storage valve share a cooling system. When the energy storage valve is in zero-power operation mode, the temperature and humidity of the battery module can be adjusted without the energy storage valve air conditioning system, but the temperature and humidity of the power module need to be adjusted by the energy storage valve air conditioning system. The main reason is that the power module generates a high amount of heat during operation. If it is not adjusted, the junction temperature will be high when the power module starts running, causing damage to the device. Since the energy storage valve air conditioning system has a large air volume, for example, the energy storage valve air conditioning system needs to run at a constant air volume for 24 hours in the rated working mode, which will cause the energy storage valve air conditioning system to consume a lot of electricity and have low operating efficiency.

[0063] In order to solve the problem of high power consumption of the energy storage valve air-conditioning system in the related art, the embodiment of the present application proposes to adjust the working mode of the energy storage valve air-conditioning system to a target working mode matching the operating mode of the energy storage valve according to the different operating modes of the energy storage valve in the energy storage valve system, so that the circulating air volume of the energy storage valve air-conditioning system can adapt to the heat generated by the energy storage valve during operation, thereby reducing the power consumption of the energy storage valve air-conditioning system and improving the operating efficiency of the energy storage valve air-conditioning system.

[0064] Figure 1 A schematic diagram of an application environment provided by an embodiment of the present application, such as Figure 1 As shown, the application environment of the embodiment of the present application may include but is not limited to: an energy storage valve system 10, a first control device 11 of the energy storage valve system 10, an energy storage valve air conditioning system 12, and a second control device 13 of the energy storage valve air conditioning system 12. It should be understood that the first control device 11 can control the components in the energy storage valve system 10, the second control device 13 can control the components in the energy storage valve air conditioning system 12, and the first control device 11 and the second control device 13 can communicate with each other.

[0065] It should be noted that the energy storage valve system 10 in the embodiment of the present application may include but is not limited to multiple energy storage valves; the first control device 11 may adopt the control method of the energy storage valve air-conditioning system provided in the embodiment of the present application.

[0066] It should be understood that the first control device 11 and the second control device 13 in the embodiment of the present application can be integrated into one control device.

[0067] For ease of understanding, the energy storage valve air conditioning system and some terms are first explained in the embodiments of the present application.

[0068] Figure 2 A schematic diagram of the structure of the energy storage valve air conditioning system provided in the embodiment of the present application is shown in FIG. Figure 2As shown, the energy storage valve air conditioning system of the embodiment of the present application may include but is not limited to the energy storage valve hall 21 of the energy storage valve, the first operating parameter monitoring module 22 near the outlet of the energy storage valve hall 21, the first fan 23 near the outlet of the energy storage valve hall 21, the mixing module 24, the processing module 25, the second fan 26 near the inlet of the energy storage valve hall 21, the second operating parameter monitoring module 27 near the inlet of the energy storage valve hall 21, the chiller 28, and the circulating water pump 29. Among them, the processing module 25 can cool, dehumidify, heat, etc. the air.

[0069] Figure 3 A schematic diagram of the deployment of the energy storage valve provided in the embodiment of the present application is shown in FIG. Figure 3 As shown, a plurality of energy storage valves 210 are disposed in the energy storage valve hall 21 .

[0070] Figure 4 A schematic diagram of the structure of the first operating parameter monitoring module provided in the embodiment of the present application is shown in FIG. Figure 4 As shown, the first operating parameter monitoring module 22 includes an inlet humidity monitoring instrument 220, an inlet temperature monitoring instrument 221 and an inlet flow monitoring instrument 222, which respectively monitor the humidity, temperature and outlet flow parameters of the outlet air of the energy storage valve hall 21.

[0071] Figure 5 A schematic diagram of the structure of the second operating parameter monitoring module provided in the embodiment of the present application, such as Figure 5 As shown, the second operating parameter monitoring module 27 includes an inlet humidity monitoring instrument 270, an inlet temperature monitoring instrument 271 and an inlet flow monitoring instrument 272, which respectively monitor the humidity, temperature and inlet flow parameters of the inlet air of the energy storage valve hall 21.

[0072] The first fan 23 is mainly used to add fresh air from the external environment of the energy storage valve hall 21 into the circulation system to meet the requirements of the slight positive pressure and ventilation rate of the energy storage valve hall 21 .

[0073] The mixing module 24 is mainly used to fully mix the fresh air and the return air.

[0074] The processing module 25 mainly performs cooling / dehumidification / heating on the mixed air to meet the operation requirements. The chiller 28 and the circulating water pump 29 transfer the heat of the air in the processing module 25 to the external environment.

[0075] Figure 6 A schematic diagram of the structure of the fan provided in the embodiment of the present application is shown in FIG. Figure 6 As shown, Figure 6 The second fan shown can be the above Figure 1 The second fan 26 shown in the figure may be a centrifugal fan, an axial flow fan or other types of fans. Figure 6 The second fan 26 shown includes a frequency converter 260 and a motor rotating component 261. The second fan 26 is mainly used to control the circulating air volume entering the energy storage valve hall 21. The second fan 26 includes a frequency converter 260 and a motor rotating component 261. The frequency converter 260 receives the instruction issued by the second control device 13, and the frequency converter 260 adjusts the rotation speed of the motor rotating component 261 based on the instruction, thereby realizing that the second fan 26 is in different operating modes.

[0076] If the first control device 11 and the second control device 13 are integrated in the same control device, the frequency converter 260 can receive the control instruction issued by the control device, and adjust the rotation speed of the motor rotating component 261 according to the control instruction, so that the second fan 26 is in different working modes, for example, the second fan 26 is operated in the rated working mode or in the low-frequency working mode. The working frequency in the rated working mode is greater than the working frequency in the low-frequency working mode.

[0077] It should be noted that the structure of the energy storage valve air conditioning system provided in the above embodiment of the present application is a schematic illustration. Of course, air conditioning systems with other structures can also be used as long as the air conditioning system includes the above Figure 6 The second fan in the embodiment can adopt the control method of the energy storage valve air-conditioning system provided in the embodiment of the present application.

[0078] The operation mode of the energy storage valve involved in the embodiments of the present application may include but is not limited to any of the following: peak shaving and valley filling operation mode, frequency modulation operation mode, and zero power operation mode. Among them, the peak shaving and valley filling operation mode may refer to the battery module in the energy storage valve being in a charging and discharging state; the frequency modulation operation mode may refer to the regulation of the frequency of the supporting power grid; the zero power operation mode may refer to the power module and the battery module in the energy storage valve being in a non-operating state. It should be noted that the heat generated by the energy storage valve in the peak shaving and valley filling operation mode or the frequency modulation operation mode will be greater than the heat generated by the energy storage valve in the zero power operation mode, and the heat generated by the energy storage valve in the peak shaving and valley filling operation mode is greater than the heat generated by the energy storage valve in the frequency modulation operation mode.

[0079] The working mode of the energy storage valve air conditioning system involved in the embodiment of the present application may include but is not limited to a rated working mode or a low-frequency working mode. Among them, the rated working frequency of the energy storage valve air conditioning system in the rated working mode is greater than the low-frequency working frequency in the low-frequency working mode. For example, the rated working frequency may be 50Hz, and the low-frequency working frequency may be 25Hz or other frequencies less than 50Hz. It should be noted that the energy storage valve air conditioning system working in the rated working mode may refer to the second fan 26 working in the rated working mode, and the energy storage valve air conditioning system working in the low-frequency working mode may refer to the second fan 26 working in the low-frequency working mode.

[0080] In the embodiment of the present application, when the working mode of the energy storage valve air conditioning system is the rated working mode, the circulating air volume at the fan outlet of the second fan in the energy storage valve air conditioning system can meet the circulating air volume required by the energy storage valve in the peak shaving and valley filling operation mode or the frequency modulation operation mode. When the working mode of the energy storage valve air conditioning system is the low-frequency working mode, the circulating air volume at the fan outlet of the second fan in the energy storage valve air conditioning system can meet the circulating air volume required for the anti-condensation and micro-positive pressure of the energy storage valve. Among them, micro-positive pressure refers to the air pressure in the valve hall of the energy storage valve being slightly greater than the ambient pressure, and the difference between the air pressure in the valve hall of the energy storage valve and the ambient pressure is generally 5-10Pa.

[0081] In the embodiment of the present application, when the energy storage valve is switched from the peak shaving and valley filling operation mode or the frequency modulation operation mode to the zero power operation mode, the operation mode of the energy storage valve air-conditioning system is controlled to be a low-frequency operation mode. In this case, the circulating air volume at the inlet of the energy storage valve valve hall in the energy storage valve air-conditioning system can meet the circulating air volume required when the energy storage valve is switched from the zero power operation mode to the peak shaving and valley filling operation mode or the frequency modulation operation mode, so as to reduce the possibility of overheating of the devices and battery modules in the power module during the switching process, resulting in device loss or thermal runaway of the battery module.

[0082] In some embodiments, Figure 7 A flow chart of a control method for an energy storage valve air conditioning system provided in some embodiments of the present application. In the embodiments of the present application, the method is applied to Figure 1 The first control device of the energy storage valve system is used as an example for explanation.

[0083] like Figure 7 As shown, the method of the embodiment of the present application may include the following steps:

[0084] Step S701: Acquire the operation mode of the energy storage valve in the energy storage valve system.

[0085] The energy storage valve system in the embodiment of the present application may include multiple energy storage valves, and any energy storage valve may include but is not limited to a power module and a battery module. Considering the compactness of the structure, each power module and each battery module in the embodiment of the present application may share the energy storage valve cooling system for cooling, so as to take away the heat generated by the energy storage valve in the energy storage valve system during operation.

[0086] Exemplarily, the operation mode of the energy storage valve in the embodiment of the present application may be a peak shaving and valley filling operation mode, a frequency modulation operation mode, or a zero power operation mode.

[0087] In this embodiment, if the energy storage valve is switched from the first operation mode to the second operation mode, the operation mode of the energy storage valve in this step is the second operation mode. Exemplarily, the first operation mode may be a peak shaving and valley filling operation mode, and the second operation mode may be a zero power operation mode; or, the first operation mode may be a peak shaving and valley filling operation mode, and the second operation mode may be a frequency modulation operation mode; or, the first operation mode may be a frequency modulation operation mode, and the second operation mode may be a zero power operation mode; or, the first operation mode may be a zero power operation mode, and the second operation mode may be a frequency modulation operation mode.

[0088] Step S702: Control the working mode of the energy storage valve air conditioning system according to a preset relationship between the operation mode of the energy storage valve and the working mode of the energy storage valve air conditioning system.

[0089] In the embodiment of the present application, the preset relationship is used to indicate the working modes of the energy storage valve air conditioning system corresponding to different operating modes of the energy storage valve. The first control device may store a preset relationship between the operating mode of the energy storage valve and the working mode of the energy storage valve air conditioning system, and the preset relationship may refer to the following Table 1:

[0090]

[0091] Table 1

[0092] In this step, in a possible implementation, during the operation of the energy storage valve, the first control device can, when detecting that the operation mode of the energy storage valve in the energy storage valve system is switched from the first operation mode to the second operation mode, control the operation mode of the energy storage valve air-conditioning system according to the preset relationship between the operation mode of the energy storage valve and the operation mode of the energy storage valve air-conditioning system. The heat generation of the energy storage valve in the first operation mode and the second operation mode is different, and the heat generation of the energy storage valve in the peak shaving and valley filling operation mode or the frequency modulation operation mode is greater than that in the zero power operation mode. Since the heat generation of the energy storage valve in the peak shaving and valley filling operation mode or the frequency modulation operation mode is greater than that in the zero power operation mode, the peak shaving and valley filling operation mode and the frequency modulation operation mode match the rated operation mode of the energy storage valve air-conditioning system, and the zero power operation mode matches the low frequency operation mode of the energy storage valve air-conditioning system, thereby achieving the saving of power consumption of the energy storage valve air-conditioning system while meeting the circulating air volume required by the energy storage valve.

[0093] Exemplarily, referring to Table 1 above, if the first operating mode in the embodiment of the present application is a zero power operating mode, and the second operating mode is a peak shaving and valley filling operating mode, in this case, the heat generated by the energy storage valve in the first operating mode is less than the heat generated in the second operating mode, and the operating mode of the energy storage valve air conditioning system is controlled to be a rated operating mode, so that the circulating air volume of the energy storage valve air conditioning system can meet the circulating air volume required by the energy storage valve in the second operating mode.

[0094] Exemplarily, referring to Table 1 above, if the first operation mode in the embodiment of the present application is a peak shaving and valley filling operation mode, and the second operation mode is a zero power operation mode, in this case, the heat generated by the energy storage valve in the first operation mode is greater than the heat generated in the second operation mode, and the operation mode of the energy storage valve air conditioning system is controlled to be a low-frequency operation mode, so that the circulating air volume of the energy storage valve air conditioning system can meet the circulating air volume required by the energy storage valve in the second operation mode.

[0095] In another possible implementation, that is, when the energy storage valve starts to operate, the operating mode of the energy storage valve air-conditioning system can be controlled to be a low-frequency operating mode according to the preset relationship shown in Table 1 above.

[0096] Exemplarily, if the energy storage valve is operating in the peak shaving and valley filling operation mode or the frequency modulation operation mode just after being started, before the operation mode switching occurs, the first control device can detect that the energy storage valve is operating in the peak shaving and valley filling operation mode or the frequency modulation operation mode. In this case, the operation mode of the energy storage valve air-conditioning system can be controlled to be the rated operation mode according to the preset relationship shown in the above Table 1.

[0097] Exemplarily, if the energy storage valve operates in the zero-power operation mode just after being started, before the operation mode switching occurs, the first control device can detect that the energy storage valve operates in the zero-power operation mode. In this case, the operation mode of the energy storage valve air-conditioning system can be controlled to be a low-frequency operation mode according to the preset relationship shown in Table 1 above.

[0098] It should be understood that the operation modes of the multiple energy storage valves in the energy storage valve system may be the same. For example, when the operation mode of any energy storage valve in the energy storage valve system is switched from the first operation mode to the second operation mode, the operation modes of the other energy storage valves in the energy storage valve system are also switched from the first operation mode to the second operation mode.

[0099] In summary, in the embodiment of the present application, the operating mode of the energy storage valve in the energy storage valve system is obtained, and the operating mode of the energy storage valve air conditioning system is controlled according to the preset relationship between the operating mode of the energy storage valve and the operating mode of the energy storage valve air conditioning system. Since the operating mode of the energy storage valve air conditioning system is controlled according to the preset relationship between the operating mode of the energy storage valve and the operating mode of the energy storage valve air conditioning system, the operating mode of the energy storage valve air conditioning system can be matched with the operating mode of the energy storage valve, so that the circulating air volume of the energy storage valve air conditioning system can adapt to the heat generated by the energy storage valve during operation, thereby saving the power consumption of the energy storage valve air conditioning system and improving the operating efficiency of the energy storage valve air conditioning system.

[0100] In some embodiments, Figure 8 As shown, Figure 8A flowchart of a method for controlling the working mode of an energy storage valve air conditioning system provided in some embodiments of the present application. Based on the above embodiments, in the embodiments of the present application, the above S702 "controlling the working mode of the energy storage valve air conditioning system according to the preset relationship between the operating mode of the energy storage valve and the working mode of the energy storage valve air conditioning system" can be implemented by the following steps:

[0101] Step S801: when it is detected that the energy storage valve in the energy storage valve system switches from the first operation mode to the second operation mode, determine a target operation mode corresponding to the second operation mode according to a preset relationship.

[0102] Exemplarily, referring to Table 1 above, if the first operating mode in the embodiment of the present application is a zero power operating mode, and the second operating mode is a peak shaving and valley filling operating mode, in this case, according to the preset relationship, the rated operating mode of the energy storage valve air conditioning system is used as the target operating mode corresponding to the second operating mode, so that the circulating air volume of the energy storage valve air conditioning system operating in the target operating mode can meet the circulating air volume required by the energy storage valve in the peak shaving and valley filling operating mode.

[0103] Exemplarily, referring to Table 1 above, if the first operating mode in the embodiment of the present application is a peak shaving and valley filling operating mode, and the second operating mode is a zero power operating mode, in this case, according to the preset relationship, the low frequency operating mode of the energy storage valve air conditioning system is used as the target operating mode corresponding to the second operating mode, so that the circulating air volume of the energy storage valve air conditioning system operating in the target operating mode can meet the circulating air volume required by the energy storage valve in the zero power operating mode.

[0104] Step S802: Control the fan near the inlet of the energy storage valve valve hall in the energy storage valve air conditioning system to operate in a target working mode.

[0105] In the embodiment of the present application, the fan near the inlet of the energy storage valve hall can be the above-mentioned Figure 6 The second fan 26 may also be an axial flow fan or other types of fans. That is, the fan in the embodiment of the present application includes various types of fans that can adjust the rotation speed of the motor rotating parts so as to work in the low frequency working mode and the rated working mode.

[0106] The first control device can send a control instruction to the second control device, and the second control device sends a control instruction to the inverter in the fan near the inlet of the energy storage valve valve hall in the energy storage valve air-conditioning system. Based on the control instruction, the inverter controls the rotation speed of the motor rotating parts in the fan, thereby realizing the fan operating in the target working mode.

[0107] In the embodiment of the present application, when it is detected that the energy storage valve in the energy storage valve system switches from the first operating mode to the second operating mode, the target operating mode corresponding to the second operating mode is determined according to the preset relationship, and the fan near the inlet of the energy storage valve valve hall in the energy storage valve air-conditioning system is controlled to operate in the target operating mode. It can be seen that in the embodiment of the present application, by adjusting the operating mode of the fan near the inlet of the energy storage valve valve hall to the target operating mode matching the operating mode of the energy storage valve according to the different operating modes of the energy storage valve in the energy storage valve system, the circulating air volume of the energy storage valve air-conditioning system can adapt to the heat generated by the energy storage valve during operation, thereby saving the power consumption of the energy storage valve air-conditioning system and improving the operating efficiency of the energy storage valve air-conditioning system. In addition, the circulating air volume of the fan in different modes meets the anti-condensation and micro-positive pressure requirements of the energy storage valve, which can reduce the power consumption of the energy storage valve air-conditioning system while ensuring the long-term reliable operation of the energy storage valve.

[0108] In order to introduce the embodiments of the present application more clearly, the following Fig. 9 , Fig.10 , Fig.11 and Fig.12 The process of switching the operating mode during the operation of the energy storage valve and controlling the second fan to operate in the target operating mode is exemplified.

[0109] In the present application embodiment, Fig. 9 As shown, Fig. 9 Schematic diagram of switching the operation mode of the energy storage valve in the energy storage valve system and the working mode of the second fan in the energy storage valve air conditioning system provided in the embodiment of the present application Figure 1 ,like Fig. 9 As shown, when the first control device detects that the operating mode of the energy storage valve in the energy storage valve system is switched from the peak shaving and valley filling operating mode to the zero power operating mode, it can determine that the target operating mode of the second fan in the energy storage valve air-conditioning system is the low-frequency operating mode, and can send a second control instruction to the second control device of the energy storage valve air-conditioning system. The second control instruction is used to instruct the second fan in the energy storage valve air-conditioning system to switch from the rated operating mode to the low-frequency operating mode after delaying the first preset time. Correspondingly, the second control device can switch the operating mode of the second fan from the rated operating mode to the low-frequency operating mode according to the second control instruction. It should be noted that the operating mode of the second fan needs to be delayed for the first preset time before switching to the low-frequency operating mode.

[0110] Exemplarily, when determining that the target operating mode of the second fan is the low-frequency operating mode, the first control device may send the second control instruction to the second control device after a delay of a first preset time period.

[0111] As another example, the first control device may send a second control instruction to the second control device when it is determined that the target operating mode of the second fan is a low-frequency operating mode, wherein the second control instruction may carry a first preset duration, so that when the second control device receives the second control instruction, it delays the first preset duration and switches the operating mode of the second fan to the low-frequency operating mode according to the second control instruction.

[0112] Further, when the first control device detects that the operation mode of the energy storage valve in the energy storage valve system is switched from the zero-power operation mode to the peak-shaving and valley-filling operation mode, it can determine that the target operation mode of the second fan in the energy storage valve air-conditioning system is the rated operation mode, and can send a first control instruction to the second control device of the energy storage valve air-conditioning system, wherein the first control instruction can be used to instruct the second fan to switch from the low-frequency operation mode to the rated operation mode. Correspondingly, the second control device can switch the operation mode of the second fan from the low-frequency operation mode to the rated operation mode according to the first control instruction.

[0113] Fig.10 Schematic diagram of switching the operating mode of the energy storage valve in the energy storage valve system and the working mode of the second fan in the energy storage valve air conditioning system provided in the embodiment of the present application Figure 2 ,like Fig.10 As shown, when the first control device detects that the operating mode of the energy storage valve in the energy storage valve system is switched from the peak shaving and valley filling operating mode to the zero power operating mode, it can determine that the target operating mode of the second fan in the energy storage valve air-conditioning system is the low-frequency operating mode, and can send a second control instruction to the second control device of the energy storage valve air-conditioning system. The second control instruction is used to instruct the second fan in the energy storage valve air-conditioning system to switch from the rated operating mode to the low-frequency operating mode after delaying the first preset time. Correspondingly, the second control device can switch the operating mode of the second fan from the rated operating mode to the low-frequency operating mode according to the second control instruction. It should be noted that the operating mode of the second fan needs to be delayed for the first preset time before switching to the low-frequency operating mode.

[0114] Further, when the first control device detects that the operation mode of the energy storage valve in the energy storage valve system is switched from the zero-power operation mode to the frequency modulation operation mode, it can determine that the target operation mode of the second fan in the energy storage valve air-conditioning system is the rated operation mode, and can send a first control instruction to the second control device of the energy storage valve air-conditioning system, wherein the first control instruction can be used to instruct the second fan to switch from the low-frequency operation mode to the rated operation mode. Correspondingly, the second control device can switch the operation mode of the second fan from the low-frequency operation mode to the rated operation mode according to the first control instruction.

[0115] Fig.11Schematic diagram of switching the operating mode of the energy storage valve in the energy storage valve system and the working mode of the second fan in the energy storage valve air conditioning system provided in the embodiment of the present application Figure 3 ,like Fig.11 As shown, when the first control device detects that the operating mode of the energy storage valve in the energy storage valve system is switched from the frequency modulation operating mode to the zero power operating mode, it can determine that the target operating mode of the second fan in the energy storage valve air-conditioning system is the low-frequency operating mode, and can send a third control instruction to the second control device of the energy storage valve air-conditioning system. Among them, the third control instruction is used to instruct the second fan in the energy storage valve air-conditioning system to switch from the rated operating mode to the low-frequency operating mode after delaying for a second preset time. Correspondingly, the second control device can switch the operating mode of the second fan from the rated operating mode to the low-frequency operating mode according to the third control instruction. It should be noted that the operating mode of the second fan needs to be delayed for a second preset time before switching to the low-frequency operating mode.

[0116] Furthermore, when the first control device detects that the operating mode of the energy storage valve in the energy storage valve system is switched from the zero-power operating mode to the frequency modulation operating mode, it can determine that the target operating mode of the second fan in the energy storage valve air-conditioning system is the rated operating mode, and can send a first control instruction to the second control device of the energy storage valve air-conditioning system, wherein the first control instruction can be used to instruct the operating mode of the second fan to be switched to the rated operating mode, so that the second control device can switch the operating mode of the second fan from the low-frequency operating mode to the rated operating mode according to the first control instruction.

[0117] Fig.12 Schematic diagram of switching the operating mode of the energy storage valve in the energy storage valve system and the working mode of the second fan in the energy storage valve air conditioning system provided in the embodiment of the present application Figure 4 ,like Fig.12 As shown, when the first control device detects that the operating mode of the energy storage valve in the energy storage valve system is switched from the frequency modulation operating mode to the zero power operating mode, it can determine that the target operating mode of the second fan in the energy storage valve air-conditioning system is the low-frequency operating mode, and can send a second control instruction to the second control device of the energy storage valve air-conditioning system. The second control instruction is used to instruct the second fan in the energy storage valve air-conditioning system to switch from the rated operating mode to the low-frequency operating mode after delaying the first preset time. Correspondingly, the second control device can switch the operating mode of the second fan from the rated operating mode to the low-frequency operating mode according to the second control instruction. It should be noted that the operating mode of the second fan needs to be delayed for the first preset time before switching to the low-frequency operating mode.

[0118] Furthermore, when the first control device detects that the operating mode of the energy storage valve in the energy storage valve system is switched from the zero-power operating mode to the peak-shaving and valley-filling operating mode, it can determine that the target operating mode of the second fan in the energy storage valve air-conditioning system is the rated operating mode, and can send a first control instruction to the second control device of the energy storage valve air-conditioning system, wherein the first control instruction can be used to instruct the operating mode of the second fan to be switched to the rated operating mode, so that the second control device can switch the operating mode of the second fan from the low-frequency operating mode to the rated operating mode according to the first control instruction.

[0119] In some embodiments, based on the above embodiments, in the embodiments of the present application, the relevant content of "determining the target operating mode corresponding to the second operating mode according to the preset relationship" in the above step S801 is further explained.

[0120] If the first operation mode is a zero power operation mode and the second operation mode is a peak shaving and valley filling operation mode or a frequency modulation operation mode, the rated operation mode of the energy storage valve air conditioning system is used as the target operation mode according to a preset relationship.

[0121] In the embodiments of this application, reference can be made to Fig. 9 , Fig.10 , Fig.11 and Fig.12 If the first operation mode is a zero power operation mode and the second operation mode is a peak shaving and valley filling operation mode or a frequency modulation operation mode, the first control device may use the rated operation mode of the energy storage valve air conditioning system as the target operation mode according to the preset relationship shown in Table 1. The first control device may control the frequency converter according to the rated operation frequency corresponding to the rated operation mode to adjust the rotation speed of the motor rotating part, thereby realizing that the second fan operates in the rated operation mode.

[0122] In the following embodiments of the present application, a process for determining the rated operating frequency and circulating air volume corresponding to the rated operating mode when the second fan operates in the rated operating mode is described.

[0123] When the energy storage valve is in the peak shaving and valley filling operation mode and the frequency modulation operation mode, and the second fan 26 is in the rated working mode, the rated working frequency S1 of the frequency converter is determined according to the following:

[0124] When the battery module and power module operate normally, the heat dissipated to the energy storage valve hall is Q1, the heat generated by the external enclosure of the energy storage valve hall is Q2, the monitored inlet air temperature of the energy storage valve hall is T1, the inlet air flow of the energy storage valve hall is F1, and the monitored outlet air temperature of the valve hall is T2. The required circulating air volume F1 is calculated as follows:

[0125] According to Q1+Q2=K1*F1*(T2-T1), we can get F1=(Q1+Q2) / KI*(T2-T1)

[0126] Among them, K1 is the first preset equivalent heat transfer calculation coefficient, which is affected by the heat transfer thermal resistance of the heat storage valve heating components and the air.

[0127] The circulating air volume of the second fan 26 at the rated operating frequency S1 must meet F1. It should be noted that F1 can be understood as the inlet air flow of the energy storage valve hall of the second fan at the rated operating frequency S1, and can also be understood as the circulating air volume at the outlet of the second fan.

[0128] The above calculation is based on the assumption that the inlet and outlet temperatures of the energy storage valve hall are fixed values. In actual projects, the temperature difference will be controlled, so the difference between T2 and T1 is generally a fixed value.

[0129] It should be noted that there is a preset mapping relationship between the circulating air volume at the outlet of the second fan and the corresponding operating frequency. Therefore, according to the required circulating air volume F1 at the outlet of the second fan, the rated operating frequency corresponding to the second fan in the rated operating mode can be determined. In addition, the circulating air volume F1 at the outlet of the second fan can meet the air volume required when the energy storage valve operates in the peak shaving and valley filling operation mode and the frequency modulation operation mode.

[0130] In summary, in the embodiment of the present application, when the first operation mode is the zero power operation mode and the second operation mode is the peak shaving and valley filling operation mode or the frequency modulation operation mode, the rated operation mode of the energy storage valve air conditioning system is used as the target operation mode according to the preset relationship. When the energy storage valve is switched to the peak shaving and valley filling operation mode or the frequency modulation operation mode with relatively large heat generation, the rated operation mode of the energy storage valve air conditioning system is used as the target operation mode, and then the energy storage valve air conditioning system is controlled to operate in the rated operation mode, so that the operation mode of the energy storage valve air conditioning system matches the operation mode of the energy storage valve, and the air volume required when the energy storage valve operates in the peak shaving and valley filling operation mode or the frequency modulation operation mode is met.

[0131] In some embodiments, based on the above embodiments, in the embodiments of the present application, the relevant content of "controlling the fan near the inlet of the energy storage valve valve hall in the energy storage valve air-conditioning system to operate in the target working mode" in the above step S802 is further explained.

[0132] A first control instruction is generated according to the rated working mode, and the first control instruction is sent to the fan, wherein the first control instruction is used to instruct the fan to switch from the low-frequency working mode to the rated working mode.

[0133] The first operation mode is a zero power operation mode, and the second operation mode is a peak shaving and valley filling operation mode or a frequency modulation operation mode, which means that before the operation mode of the energy storage valve is switched, the energy storage valve operates in a zero power operation mode, and accordingly, the fan operates in a rated operation mode. After the operation mode of the energy storage valve is switched, the energy storage valve operates in a peak shaving and valley filling operation mode or a frequency modulation operation mode, and the first control device can preset a relationship to take the rated operation mode as the target operation mode, and generate a first control instruction according to the rated operation mode, and send the first control instruction to the fan, so that after the frequency converter in the fan receives the first control instruction, it adjusts the rotation speed of the motor rotating part based on the first control instruction, thereby realizing the fan switching from the low frequency operation mode to the rated operation mode.

[0134] In summary, in the embodiments of the present application, when the first operating mode is the zero-power operating mode and the second operating mode is the peak-shaving and valley-filling operating mode or the frequency modulation operating mode, the first control device takes the rated operating mode as the target operating mode, and then generates a first control instruction according to the rated operating mode, and sends the first control instruction to the fan to switch the fan from the low-frequency operating mode to the rated operating mode, so that the operating mode of the energy storage valve air-conditioning system matches the operating mode of the energy storage valve, and meets the air volume required when the energy storage valve operates in the peak-shaving and valley-filling operating mode and the frequency modulation operating mode.

[0135] In some embodiments, based on the above embodiments, in the embodiments of the present application, the relevant content of "determining the target operating mode corresponding to the second operating mode according to the preset relationship" in the above step S801 is further explained.

[0136] If the first operating mode is a peak shaving and valley filling operating mode or a frequency modulation operating mode, and the second operating mode is a zero power operating mode, the low frequency operating mode of the energy storage valve air conditioning system is used as the target operating mode according to a preset relationship.

[0137] In the embodiments of this application, reference can be made to Fig. 9 , Fig.10 , Fig.11 and Fig.12 If the first operation mode is a peak shaving and valley filling operation mode or a frequency modulation operation mode, and the second operation mode is a zero power operation mode, the first control device may use the low frequency operation mode of the energy storage valve air conditioning system as the target operation mode according to the preset relationship shown in Table 1. The first control device may control the frequency converter according to the low frequency operation frequency corresponding to the low frequency operation mode to adjust the rotation speed of the motor rotating part, thereby realizing that the second fan operates in the low frequency operation mode.

[0138] In the following embodiments of the present application, when the second fan operates in a low-frequency operating mode, a process for determining the low-frequency operating frequency and the circulating air volume corresponding to the low-frequency operating mode is described.

[0139] When the energy storage valve is in the peak shaving and valley filling operation mode and the frequency modulation operation mode, and the second fan 26 is in the low frequency operation mode, the low frequency operation frequency S2 of the frequency converter is determined according to the following:

[0140] Although the energy storage valve stops running, due to the thermal inertia of the energy storage valve equipment, the energy storage valve air conditioning system needs to delay for a period of time to fully cool the energy storage valve. In addition, since the cooling water circuit is always running, in order to prevent condensation of the cooling water circuit and maintain a slight positive pressure in the valve hall, the following two aspects of control are required:

[0141] First aspect: when the second control device receives the control instruction sent by the first control device, it is necessary to control the second fan to continue to maintain the rated operation mode for a certain period of time, and then switch to the low-frequency operation mode after a certain delay;

[0142] Second aspect: The circulating air volume corresponding to the low-frequency operating frequency S2 of the second fan in the low-frequency operating mode must meet the following conditions:

[0143] According to Q2=K2*F2*(T2-T1), we can get F2=(Q2) / K2*(T2-T1)

[0144] The circulating air volume of the second fan at the low-frequency operating frequency S2 must satisfy F2. It should be noted that F2 can be understood as the inlet air flow rate of the energy storage valve hall of the second fan at the low-frequency operating frequency, and can also be understood as the circulating air volume at the outlet of the second fan.

[0145] In summary, in the embodiment of the present application, if the first operating mode is a peak shaving and valley filling operating mode or a frequency modulation operating mode, and the second operating mode is a zero power operating mode, then according to the preset relationship, the low frequency operating mode of the energy storage valve air conditioning system is used as the target operating mode. When the energy storage valve is switched to a zero power operating mode with relatively small heat production, the low frequency operating mode of the energy storage valve air conditioning system is used as the target operating mode, and then the energy storage valve air conditioning system is controlled to operate in a low frequency operating mode, so that the operating mode of the energy storage valve air conditioning system matches the operating mode of the energy storage valve, and the required air volume is met when the energy storage valve operates in the zero power operating mode. In addition, the circulating air volume of the second fan operating in the low frequency operating mode meets the anti-condensation and micro-positive pressure requirements of the energy storage valve, which can reduce the power consumption of the energy storage valve air conditioning system while ensuring the long-term reliable operation of the energy storage valve.

[0146] In some embodiments, based on the above embodiments, in the embodiments of the present application, the relevant content of "controlling the fan near the inlet of the energy storage valve valve hall in the energy storage valve air-conditioning system to operate in the target working mode" in the above step S802 is further explained.

[0147] If the first operation mode is the peak shaving and valley filling operation mode, a second control instruction is generated according to the low-frequency operation mode, and the second control instruction is sent to the wind turbine, wherein the second control instruction is used to instruct the wind turbine to switch from the rated operation mode to the low-frequency operation mode after a delay of a first preset time;

[0148] If the first operating mode is the frequency modulation operating mode, a third control instruction is generated according to the low-frequency operating mode, and the third control instruction is sent to the fan, wherein the third control instruction is used to instruct the fan to switch from the rated operating mode to the low-frequency operating mode after a delay of a second preset time; the first preset time is greater than the second preset time.

[0149] In the embodiments of this application, reference can be made to Fig. 9 , Fig.10 , Fig.11 and Fig.12 If the first operation mode is the peak shaving and valley filling operation mode and the second operation mode is the zero power operation mode, the first control device may send a second control instruction to the second control device to instruct the second fan to switch from the rated operation mode to the low frequency operation mode after delaying for the first preset time. If the first operation mode is the frequency modulation operation mode and the second operation mode is the zero power operation mode, the first control device may send a third control instruction to the second control device to instruct the second fan to switch from the rated operation mode to the low frequency operation mode after delaying for the second preset time.

[0150] It should be noted that since the energy storage valve generally operates in the frequency modulation operation mode for a short time and the heat generated is relatively less than the heat generated in the peak shaving and valley filling operation mode, when the energy storage valve switches from the frequency modulation operation mode to the zero power operation mode, the delay time is less than the delay time for the energy storage valve to switch from the frequency modulation operation mode to the zero power operation mode, that is, the second preset time is less than the first preset time, thereby achieving the delay and the time required for the actual situation, and making the second fan enter the low-frequency working mode as early as possible, thereby further saving the power consumption of the energy storage valve air-conditioning system.

[0151] In summary, in the embodiments of the present application, when the energy storage valve is switched to the zero-power operation mode with relatively small heat generation, the low-frequency operation mode of the energy storage valve air-conditioning system can be used as the target operation mode, and then the energy storage valve air-conditioning system can be controlled to operate in the low-frequency operation mode, so that the operation mode of the energy storage valve air-conditioning system matches the operation mode of the energy storage valve, and the air volume required when the energy storage valve operates in the zero-power operation mode is met. In addition, the circulating air volume of the second fan operating in the low-frequency operation mode meets the anti-condensation and micro-positive pressure requirements of the energy storage valve, while reducing the power consumption of the energy storage valve air-conditioning system, it can also ensure the long-term reliable operation of the energy storage valve. In addition, the second preset time length is less than the first preset time length, so as to achieve the delay and the time length required by the actual situation, so that the second fan enters the low-frequency operation mode as early as possible, thereby further saving the power consumption of the energy storage valve air-conditioning system.

[0152] In some embodiments, based on the above embodiments, in the embodiments of the present application, the relevant content of "determining the target operating mode corresponding to the second operating mode according to the preset relationship" in the above step S801 is further explained.

[0153] If the first operation mode is the peak shaving and valley filling operation mode, and the second operation mode is the frequency modulation operation mode, then according to the preset relationship, the rated operation mode of the energy storage valve air conditioning system is used as the target operation mode.

[0154] Based on the preset relationship shown in the above Table 1, it can be determined that when the energy storage valve switches from the peak shaving and valley filling operation mode to the frequency modulation operation mode, it means that the operation mode of the energy storage valve after switching is the frequency modulation operation mode, and the frequency modulation operation mode corresponds to the rated operating mode of the energy storage valve air-conditioning system. Therefore, the rated operating mode of the energy storage valve air-conditioning system is used as the target operating mode.

[0155] In the embodiment of the present application, when the first operating mode is the peak shaving and valley filling operating mode and the second operating mode is the frequency modulation operating mode, the rated operating mode of the energy storage valve air-conditioning system is used as the target operating mode according to a preset relationship, so that the fan near the inlet of the energy storage valve valve hall in the energy storage valve air-conditioning system is maintained in the rated operating mode, and the operating mode of the second fan in the energy storage valve air-conditioning system is matched with the operating mode of the energy storage valve system.

[0156] In some embodiments, based on the above embodiments, in the embodiments of the present application, the relevant content of "determining the target operating mode corresponding to the second operating mode according to the preset relationship" in the above step S801 is further explained.

[0157] If the first operation mode is the frequency modulation operation mode and the second operation mode is the peak shaving and valley filling operation mode, then according to the preset relationship, the rated operation mode of the energy storage valve air conditioning system is used as the target operation mode.

[0158] Based on the preset relationship shown in the above Table 1, it can be determined that when the energy storage valve is switched from the frequency modulation operation mode to the peak shaving and valley filling operation mode, it means that the operation mode of the energy storage valve after switching is the peak shaving and valley filling operation mode, and the peak shaving and valley filling operation mode corresponds to the rated working mode of the energy storage valve air-conditioning system. Therefore, the rated working mode of the energy storage valve air-conditioning system is used as the target working mode.

[0159] In the embodiment of the present application, when the first operating mode is the frequency modulation operating mode and the second operating mode is the peak shaving and valley filling operating mode, the rated operating mode of the energy storage valve air-conditioning system is used as the target operating mode according to a preset relationship, so that the fan near the inlet of the energy storage valve valve hall in the energy storage valve air-conditioning system is maintained in the rated operating mode, and the operating mode of the second fan in the energy storage valve air-conditioning system is matched with the operating mode of the energy storage valve system.
