[0086] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

[0087] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art 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 term "include" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0088] In the description of the embodiments of this application, the technical terms "first" and "second" are used only to distinguish different objects and should not 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 this application, the meaning of "plurality" is two or more (including two), unless otherwise clearly and specifically defined.

[0089] The energy storage valve control system, method, apparatus, device, and energy storage device provided in the embodiments of the present application can be applied to control application scenarios of high-pressure direct-mounted energy storage valves; of course, they can also be applied to other application scenarios.

[0090] High-voltage direct-mounted energy storage technology integrates the voltage source converter (VSC) converter valve and the DC energy storage valve into a high-voltage direct-mounted energy storage valve (or simply a high-voltage energy storage valve), which has the advantages of high modularity and high operational reliability.

[0091] Typically, a high-pressure energy storage valve may include multiple energy storage modules, each of which may include a power module and a battery module. During operation, the power module and the battery module will generate heat. Considering the operating life of the battery module, a storage valve cooling system may be provided for water-cooled temperature control, with the cooling water inlet temperature generally controlled between 18°C ​​and 20°C. In addition, the energy storage valve has a high operating voltage level and high temperature, so an energy storage valve air conditioning system, or a heating ventilation and air conditioning (HVAC) system, is required to regulate the ambient temperature and humidity of the energy storage valve, so as to alleviate the problem of insulation failure caused by condensation on the surface of the cooling water pipe, thereby facilitating the normal operation of the energy storage valve.

[0092] In the related technology, operation and maintenance personnel are required to monitor the operation of the HVAC system, but there may be situations where the operation and maintenance personnel cannot detect abnormal operation of the HVAC system in time. The energy storage valve has relatively high requirements for ambient temperature and humidity. There may be large deviations in ambient temperature and humidity, and condensation water may appear on the surface of the cooling water pipe, causing insulation failure. Therefore, the operating stability of the energy storage valve in the related technology needs to be improved.

[0093] It should be noted that the DC energy storage valve control device serves as the "brain" of the high-voltage energy storage valve, working in conjunction with the VSC converter valve control device to implement peak shaving, frequency regulation, inertia support, black start, and island power transmission functions for the AC power grid. The DC energy storage valve control device is called an energy valve base controller (EVBC).

[0094] It should be understood that the control device of the DC energy storage valve and the control device of the VSC converter valve in the embodiment of the present application can be set separately and independently, or can be integrated into one control device.

[0095] In order to solve the problem in the related art that the operating stability of the energy storage valve needs to be improved, the embodiment of the present application proposes that the HVAC system control device can send the operating information of the monitored HVAC system to the energy storage valve control device, so that the energy storage valve control device can adaptively control the operating state of the energy storage valve according to the operating information of the HVAC system sent by the HVAC system control device, thereby realizing the linkage control of the energy storage valve control device and the HVAC system control device, so that when the HVAC system is unreliable, the operating state of the energy storage valve can be adjusted in time, which is conducive to improving the operating stability of the energy storage valve.

[0099] It should be noted that the energy storage valve control device 11 and the HVAC system control device 13 in the embodiment of the present application can also be integrated into one control device.

[0100] In some embodiments, FIG2 is a schematic diagram of the structure of an energy storage valve control system provided in some embodiments of the present application. As shown in FIG2, the control system in the embodiments of the present application may include, but is not limited to, an energy storage valve control device 11 and a HVAC system control device 13. The energy storage valve control device 11 and the HVAC system control device 13 may be interconnected so that the two can communicate with each other.

[0101] For example, the energy storage valve control device 11 and the HVAC system control device 13 can be connected via a wired connection (e.g., an optical fiber connection) or a wireless connection. Accordingly, the connection between any two modules involved in the embodiments of the present application can be connected via a wired connection or a wireless connection.

[0102] The HVAC system control device 13 in the embodiment of the present application can be configured to monitor the operating information of the HVAC system and send the operating information to the energy storage valve control device 11, wherein the operating information can be relevant information for indicating the operating status of the HVAC system, which is conducive to alleviating the insulation failure of the energy storage valve.

[0104] The equipment status information of the HVAC system in the embodiment of the present application can be used to indicate the operating status of the HVAC equipment in the HVAC system. For example, the HVAC equipment may include but is not limited to at least one of the following: an air conditioner, a compressor, a chiller, a combined air handling unit, a water pump (or a chilled water pump), a constant pressure water supply device, a cold water pipe, and a water supply tank. It should be understood that in order to increase the reliability of the energy storage valve air conditioning system, the embodiment of the present application includes two chillers that serve as a primary and backup for each other, two combined air handling units that serve as a primary and backup for each other, and two water pumps that serve as a primary and backup for each other.

[0108] It should be understood that in this implementation, the HVAC system control device can determine whether the HVAC system has preset abnormal operating conditions, whether the HVAC system has preset normal operating conditions, and / or whether the HVAC system has preset early warning conditions based on the acquired information after obtaining at least one of the following information: the equipment status information of the HVAC system, the alarm information of the HVAC system, and the environmental information of the energy storage valve during the operation of the HVAC system.

[0109] The HVAC system in the embodiment of the present application can be configured to stabilize the preset temperature and humidity of the environment in which the energy storage valve is located during operation, which is conducive to ensuring that the temperature and humidity information of the environment in which the energy storage valve is located during operation can meet the preset temperature and humidity requirements.

[0110] It should be understood that the HVAC system can also stabilize the temperature and humidity of the energy storage valve itself during operation while stabilizing the preset temperature and humidity of the environment in which the energy storage valve is located during operation.

[0111] For example, the HVAC system control device 13 in the embodiment of the present application may also be configured to adjust the operating mode of the HVAC system according to a preset operating mode to stabilize the preset temperature and humidity of the environment in which the energy storage valve is located during operation.

[0112] As another example, the HVAC system control device 13 in the embodiment of the present application may be further configured to obtain mode adjustment instruction information and adjust the operating mode of the HVAC system according to the mode adjustment instruction information to stabilize the preset temperature and humidity of the environment in which the energy storage valve operates. The mode adjustment instruction information may be obtained by the HVAC system control device from the energy storage valve control device, or by the HVAC system control device from another device.

[0113] Of course, the HVAC system control device 13 can also stabilize the preset temperature and humidity of the environment in which the energy storage valve is operating in other ways.

[0114] The energy storage valve control device 11 in the embodiment of the present application can be configured to control the operating state of the energy storage valve according to the operating information sent by the HVAC system control device. For example, the operating state may include but is not limited to: stop operation, start operation, lock, and unlock.

[0115] Optionally, the energy storage valve control device 11 can determine the operating status of the HVAC system based on the operating information of the HVAC system sent by the HVAC system control device, and form a control strategy based on the operating status of the HVAC system to adaptively control the operating state of the energy storage valve, so that when the HVAC system is unreliable, the operating state of the energy storage valve can be adjusted in time, which is conducive to improving the operating stability of the energy storage valve.

[0116] Of course, the energy storage valve control device 11 in the embodiment of the present application may also have other functions, for example, the energy storage valve control device 11 may form an early warning strategy based on the operating information of the HVAC system; the HVAC system control device 13 in the embodiment of the present application may also have other functions, for example, the HVAC system control device 13 may form an early warning strategy based on the operating information of the HVAC system.

[0117] In summary, the energy storage valve control system in the embodiment of the present application may include an energy storage valve control device and a HVAC system control device that are interconnected. Among them, the HVAC system control device can be configured to monitor the operating information of the HVAC system and send the operating information to the energy storage valve control device, and the HVAC system can be configured to stabilize the preset temperature and humidity of the environment in which the energy storage valve is located during operation. The energy storage valve control device can be configured to control the operating state of the energy storage valve according to the operating information. It can be seen that in the embodiment of the present application, the HVAC system control device can send the monitored operating information of the HVAC system to the energy storage valve control device, so that the energy storage valve control device can adaptively control the operating state of the energy storage valve according to the operating information of the HVAC system sent by the HVAC system control device, thereby realizing the linkage control of the energy storage valve control device and the HVAC system control device, so that when the HVAC system is unreliable, the operating state of the energy storage valve can be adjusted in time, which is conducive to improving the operating stability of the energy storage valve.

[0118] In some embodiments, based on the above embodiments, the energy storage valve of the present application may include, but is not limited to, at least one battery module. For example, the battery module involved in the present application may include, but is not limited to, at least one of the following: a battery cell, a battery pack, a battery cluster, or a battery stack.

[0119] Optionally, each battery module in the energy storage valve of the embodiment of the present application may have a battery temperature acquisition unit, wherein the battery temperature acquisition unit may be configured to acquire temperature information of the corresponding battery module. It should be understood that the battery temperature acquisition unit and the battery module may be arranged one-to-one, or one-to-many.

[0120] For example, the battery temperature acquisition unit in the embodiment of the present application can be communicatively connected to the HVAC system control device so that the collected temperature information of the corresponding battery module can be sent to the HVAC system control device, thereby realizing the coordinated control of the HVAC system control device and the battery module. This is beneficial for adjusting the operating mode of the HVAC system to cooperate with the battery cooling system when the temperature of the battery module changes, thereby alleviating the problem of insulation failure caused by condensation water on the surface of the cooling water pipe due to temperature and humidity differences. It should be noted that the communication connection between any two modules or units involved in the embodiment of the present application may include but is not limited to a direct communication connection or an indirect communication connection.

[0121] In one possible implementation, the battery temperature acquisition unit in the embodiment of the present application can be directly connected to the HVAC system control device for communication, so that the collected temperature information of the battery module can be sent to the HVAC system control device. This not only realizes the linkage control of the HVAC system control device and the battery module, but also improves the transmission efficiency of the temperature information of the battery module, which is beneficial for the HVAC system control device to obtain the temperature information of the battery module in a timely manner, so that the operation mode can be adjusted in time to stabilize the temperature of the energy storage valve itself during the operation of the energy storage valve.

[0122] In another possible implementation, the battery temperature acquisition unit in the embodiment of the present application can be indirectly connected to the HVAC system control device so that the collected temperature information of the battery module can be indirectly sent to the HVAC system control device, thereby realizing the linkage control of the HVAC system control device and the battery module, so that the HVAC system control device can obtain the temperature information of the battery module, and thus can adjust the operating mode in time to stabilize the temperature of the energy storage valve itself during the operation of the energy storage valve.

[0123] For example, the battery temperature acquisition unit may be communicatively connected to the HVAC system control device via the battery module control device, so that the battery temperature acquisition unit may send the collected temperature information of the battery module to the HVAC system control device via the battery module control device.

[0124] In another example, the battery temperature acquisition unit can be communicatively connected to the HVAC system control device through the energy storage valve control device, so that the battery temperature acquisition unit can send the collected temperature information of the battery module to the HVAC system control device through the energy storage valve control device.

[0125] As another example, the battery temperature acquisition unit can be communicatively connected to the energy storage valve control device through the battery module control device, and the energy storage valve control device is communicatively connected to the HVAC system control device, so that the battery temperature acquisition unit can send the collected battery module temperature information to the energy storage valve control device through the battery module control device, and then send it to the HVAC system control device through the energy storage valve control device.

[0126] It should be understood that the battery module control device can be directly connected to the energy storage valve control device 11, or can be indirectly connected to the energy storage valve control device 11 through other modules (for example, the power module control device, etc.), so that the temperature information of each battery module can be sent to the energy storage valve control device 11, so that the energy storage valve control device 11 can monitor the temperature of each battery module according to the temperature information of each battery module, thereby realizing the linkage control of the energy storage valve control device and the battery module control device.

[0127] In addition, the battery module control device in the embodiment of the present application can also be configured to be responsible for the control and protection of each battery module to prevent insulation failure and achieve accurate monitoring and transmission of the temperature of each battery module.

[0128] Of course, the battery temperature acquisition unit can also be connected to the HVAC system control device in other ways.

[0129] For ease of understanding, the following embodiments of the present application take the indirect communication connection between the battery module control device and the HVAC system control device as an example to provide an illustrative introduction to the communication connection method between the battery module control device, the power module control device, the energy storage valve control device and the HVAC system control device.

[0130] In some embodiments, Figure 3 is a structural schematic diagram of the energy storage valve control system provided in other embodiments of the present application. As shown in Figure 3, the power module control device 15 in the embodiment of the present application can be arranged between the battery module control device 14 and the energy storage valve control device 11, wherein the two ends of the power module control device 15 can be connected to the battery module control device 14 and the energy storage valve control device 11 respectively, so that the battery module control device 14 can send the temperature information of each battery module to the energy storage valve control device 11 through the power module control device 15.

[0131] The power module control device 15 in the embodiment of the present application can be used to control the operating state of each power module in the energy storage valve under the control of the energy storage valve control device 11, thereby achieving control of the operating state of the energy storage valve. For example, the operating state of the power module can include but is not limited to locked or unlocked.

[0132] It should be understood that if the operating state of each power module in the energy storage valve is a locked state, the energy storage valve is in a stopped operating state; if the operating state of some power modules in the energy storage valve is an unlocked state, the energy storage valve is in an operating state.

[0133] Of course, the power module control device 15 in the embodiment of the present application may also have other functions, for example, the power module control device 15 may provide protection functions for each power module, and / or be responsible for sending the reporting information of other modules (for example, the temperature information of each battery module of the battery module control device) to the energy storage valve control device 11, etc.

[0134] In the embodiment of the present application, the battery module control device 14 is connected to the energy storage valve control device 11 through the power module control device 15, without modifying the connection method between the power module control device 15 and the energy storage valve control device 11 in the relevant technology, thereby realizing an indirect connection between the battery module control device 14 and the energy storage valve control device 11, so as to facilitate communication linkage between the energy storage valve control device and the battery module control device.

[0135] In some embodiments, Figure 4 is a structural schematic diagram of the energy storage valve control system provided in other embodiments of the present application. As shown in Figure 4, the battery module control device 14 in the embodiments of the present application may include multiple battery module control units 141, and the power module control device 15 may include multiple power module control units 151.

[0136] For example, each battery module control unit 141 in the embodiment of the present application can be used to obtain temperature information of at least one battery module in the energy storage valve and send the temperature information of at least one battery module to the energy storage valve control device 11. Different battery module control units 141 can be used to obtain temperature information of different battery modules, which helps the battery module control unit 141 to quickly detect the temperature information of the corresponding battery module and send it to the energy storage valve control device 11 in a timely manner, thereby improving the control efficiency of the energy storage valve.

[0137] Each power module control unit 151 in the embodiment of the present application can be used to control the operating state of at least one power module in the energy storage valve under the control of the energy storage valve control device 11. Different power module control units 151 can be used to control the operating states of different power modules, which helps the power module control unit 151 to quickly control the operating state of the corresponding power module, thereby improving the control efficiency of the energy storage valve.

[0138] Exemplarily, each battery module control unit 141 can be connected to the corresponding power module control unit 151 in a one-to-one correspondence, so that each battery module control unit 141 can be connected to the energy storage valve control device 11 through the corresponding power module control unit 151.

[0139] It should be understood that the different units in Figure 4 and / or the different devices are connected in an optical fiber manner, and the transmission method is illustrated by the IEC60044-8 communication protocol as an example; of course, the different units and / or the different devices can also be connected in other ways, and the transmission method can also be transmitted through other communication protocols, which will not be explained one by one in the embodiments of the present application.

[0140] It can be seen that the battery module control unit 141 and the power module control unit 151 in the embodiment of the present application are connected one-to-one, the power module control unit 151 and the energy storage valve control device 11 are connected one-to-one, and the energy storage valve control device 11 and the HVAC system control device 13 are connected one-to-one, thereby realizing a non-redundant communication architecture for the linkage control of the energy storage valve control device 11, the battery module control device 14, the power module control device 15 and the HVAC system control device 13. The number of optical fibers required is small, which can save costs.

[0141] In some embodiments, Figure 5 is a structural schematic diagram of the energy storage valve control system provided in other embodiments of the present application. As shown in Figure 5, the battery module control device 14 and the power module control device 15 in the embodiments of the present application can be respectively connected to the energy storage valve control device 11, so that the battery module control device 14 can directly send the temperature information of each battery module to the energy storage valve control device 11, so that the energy storage valve control device 11 can send the temperature information of each battery module to the HVAC system control device 13, which is conducive to improving the transmission efficiency of temperature information.

[0142] In some embodiments, Figure 6 is a structural schematic diagram of the energy storage valve control system provided in other embodiments of the present application. As shown in Figure 6, the battery module control device 14 in the embodiments of the present application may include multiple battery module control units 141, and the power module control device 15 may include multiple power module control units 151.

[0143] Illustratively, each battery module control unit 141 may be connected to the energy storage valve control device 11 , respectively, so that each battery module control unit 141 may quickly send the detected temperature information of the corresponding battery module to the energy storage valve control device 11 .

[0144] Exemplarily, each power module control unit 151 can be connected to the energy storage valve control device 11 respectively, so that each power module control unit 151 can quickly control the operating status of the corresponding power module under the control of the energy storage valve control device 11, thereby helping to improve the control efficiency of the energy storage valve.

[0145] It should be understood that the different units in Figure 6 and / or the different devices are connected in an optical fiber manner, and the transmission method is illustrated by the IEC60044-8 communication protocol as an example; of course, the different units and / or the different devices can also be connected in other ways, and the transmission method can also be transmitted through other communication protocols, which will not be explained one by one in the embodiments of the present application.

[0146] It can be seen that the battery module control unit 141 and the energy storage valve control device 11 in the embodiment of the present application are connected one-to-one, the power module control unit 151 and the energy storage valve control device 11 are connected one-to-one, and the energy storage valve control device 11 and the HVAC system control device 13 are connected one-to-one, thereby realizing a non-redundant communication architecture for the linkage control of the energy storage valve control device 11, the battery module control device 14, the power module control device 15 and the HVAC system control device 13, which facilitates the unit expansion of the battery module control device 14 and the power module control device 15.

[0147] In some embodiments, based on the above embodiments, FIG7 is a schematic structural diagram of an energy storage valve control system provided in other embodiments of the present application. As shown in FIG7 , in order to enhance the reliability of the control system, the energy storage valve control system in the embodiment of the present application may include multiple mutually redundant energy storage valve control devices 11. Among them, the multiple mutually redundant energy storage valve control devices 11 can be connected to the HVAC system control device 13 respectively, and the multiple mutually redundant energy storage valve control devices 11 can be connected to each other, so that the multiple mutually redundant energy storage valve control devices 11 can share the first system information (for example, the operation information of the HVAC system, the operation status of the energy storage valve, and / or the system health status, etc.), and perform master-slave switching according to the health level, so that the energy storage valve control device 11 with a higher health level serves as the master energy storage valve control device.

[0148] For example, the energy storage valve control device 11 with the highest health level among the multiple redundant energy storage valve control devices 11 in the embodiment of the present application can be configured to control the operating state of the energy storage valve according to the operating information of the HVAC system.

[0149] For ease of understanding, in the following embodiments of the present application, the control system including two mutually redundant energy storage valve control devices 11 is taken as an example to exemplify the relevant contents of the active-standby switching.

[0150] In some embodiments, FIG8 is a schematic diagram of the master-slave switching of the energy storage valve control device provided in an embodiment of the present application. As shown in FIG8, two mutually redundant energy storage valve control devices A and energy storage valve control device B are communicatively connected, and the master-slave redundancy switching logic can be implemented according to the health level, so that the energy storage valve control device with a higher health level serves as the master energy storage valve control device. For example, if the health level of energy storage valve control device A is higher than the health level of energy storage valve control device B, energy storage valve control device A is the master energy storage valve control device and energy storage valve control device B is the backup energy storage valve control device; if the health level of energy storage valve control device B is higher than the health level of energy storage valve control device A, energy storage valve control device B is switched to the master energy storage valve control device and energy storage valve control device A is switched to the backup energy storage valve control device.

[0151] It should be understood that during the master-slave switching process, it is possible that "two energy storage valve control devices are simultaneously the master energy storage valve control devices" or "two energy storage valve control devices are simultaneously the backup energy storage valve control devices." To facilitate the management and control of the monitoring device, an alarm message can be sent to the monitoring device in the event that "two energy storage valve control devices are simultaneously the master energy storage valve control devices" or "two energy storage valve control devices are simultaneously the backup energy storage valve control devices."

[0152] In the case where "the energy storage valve control device is also the main energy storage valve control device", the "latter master is the main" device, that is, the device that later becomes the main energy storage valve control device, can be used as the main energy storage valve control device.

[0153] In the case where "two energy storage valve control devices are both backup energy storage valve control devices", the "original master as main" method can be adopted, that is, the main energy storage valve control device is first used as the main energy storage valve control device, and the backup energy storage valve control device is first used as the backup energy storage valve control device.

[0154] For ease of understanding, in the following embodiments of the present application, an energy storage valve control system is exemplarily introduced and described by taking a control system including two mutually redundant energy storage valve control devices 11 as an example.

The battery module control device 14 and the power module control device 15 may be connected to the two mutually redundant energy storage valve control devices 11, respectively.

[0158] It can be seen that in the embodiment of the present application, the battery module control device 14 and the power module control device 15 are respectively connected to two redundant energy storage valve control devices 11, and the HVAC system control device 13 is respectively connected to two redundant energy storage valve control devices 11. This not only realizes the dual redundant communication architecture of the linked control energy storage valve control device 11, which is beneficial to improving the reliability of the control system, but also the battery module control device 14 can quickly send the acquired temperature information of the corresponding battery module to the energy storage valve control device 11, which is beneficial to improving the control efficiency of the control system.

[0160] The two mutually redundant energy storage valve control devices 11 may be connected to the HVAC system control device 13 respectively, and the two mutually redundant energy storage valve control devices 11 may be connected to each other.

[0161] Each battery module control unit 141 may be connected to a corresponding power module control unit 151 in a one-to-one correspondence, and each power module control unit 151 may be connected to two redundant energy storage valve control devices 11 .

[0162] In some embodiments, FIG12 is a schematic diagram of the structure of an energy storage valve control system provided in other embodiments of the present application.

[0164] Each battery module control unit 141 may be connected to two mutually redundant energy storage valve control devices 11 , and each power module control unit 151 may be connected to two mutually redundant energy storage valve control devices 11 .

[0165] In some embodiments, based on the above embodiments, FIG13 is a schematic structural diagram of an energy storage valve control system provided in other embodiments of the present application. As shown in FIG13 , in order to further enhance the reliability of the control system, the control system in the embodiment of the present application may include multiple mutually redundant HVAC system control devices 13. Each energy storage valve control device 13 may be connected to multiple mutually redundant HVAC system control devices 11, and multiple mutually redundant HVAC system control devices 13 may be connected to each other, so that multiple mutually redundant HVAC system control devices 13 can share system information (e.g., HVAC system operation information and / or system health status, etc.), and perform master-slave switching based on health level, so that the HVAC system control device 13 with a higher health level serves as the master HVAC system control device.

[0166] For example, the HVAC system control device with the highest health level among the multiple redundant HVAC system control devices 13 in the embodiment of the present application (or referred to as the main HVAC system control device) can be configured to monitor the operating information of the HVAC system and send the operating information to the energy storage valve control device with the highest health level among the multiple redundant energy storage valve control devices 11 (or referred to as the main energy storage valve control device), so that the main energy storage valve control device can control the operating status of the energy storage valve according to the operating information of the HVAC system.

[0167] It can be seen that in the embodiment of the present application, by means of dual-device redundant connection of the energy storage valve control device 13 and the HVAC system control device 11, the master-slave redundant switching logic is implemented according to the health level, so that the energy storage valve control device with the highest health level and the HVAC system control device with the highest health level can be linked and controlled, thereby helping to enhance the reliability of the control system.

[0168] It should be noted that the master-slave switching method of the multiple redundant HVAC system control devices 13 in the embodiment of the present application can refer to the master-slave switching method of the multiple redundant energy storage valve control devices 11 in the above embodiment, and will not be repeated here.

As shown in FIG16 , the control system in the embodiment of the present application may include: two mutually redundant energy storage valve control devices 11, two mutually redundant HVAC system control devices 13, a battery module control device 14, and a power module control device 15. The battery module control device 14 may include multiple battery module control units 141, and the power module control device 15 may include multiple power module control units 151.

[0176] Each battery module control unit 141 may be connected to a corresponding power module control unit 151 in a one-to-one correspondence, and each power module control unit 151 may be connected to two redundant energy storage valve control devices 11 .

[0177] It should be understood that the different units in Figure 16 and / or the different devices are connected by optical fiber, and the transmission method is illustrated by the IEC60044-8 communication protocol as an example; of course, the different units and / or different devices can also be connected by other methods, and the transmission method can also be transmitted through other communication protocols, which will not be explained one by one in the embodiments of the present application.

[0178] It can be seen that the battery module control unit 141 and the power module control unit 151 in the embodiment of the present application are connected one-to-one, the power module control unit 151 and the two energy storage valve control devices 11 are cross-redundantly connected, the two energy storage valve control devices 11 and the two HVAC system control devices 13 are cross-redundantly connected, and the two energy storage valve control devices 11 are connected to each other, and the two HVAC system control devices 13 are connected to each other, thereby realizing a dual-set redundant communication architecture for the linkage control of the energy storage valve control device 11, the battery module control device 14, the power module control device 15 and the HVAC system control device 13. Not only does it require a small number of optical fibers, which can save costs, but it can also enhance the reliability of the control system.

[0179] In some embodiments, FIG17 is a schematic diagram of the structure of an energy storage valve control system provided in other embodiments of the present application. As shown in FIG17 , the control system in the embodiment of the present application may include: two mutually redundant energy storage valve control devices 11, two mutually redundant HVAC system control devices 13, a battery module control device 14, and a power module control device 15. The battery module control device 14 may include multiple battery module control units 141, and the power module control device 15 may include multiple power module control units 151.

[0181] Each battery module control unit 141 may be connected to two mutually redundant energy storage valve control devices 11 , and each power module control unit 151 may be connected to two mutually redundant energy storage valve control devices 11 .

[0182] It should be understood that the different units in Figure 17 and / or the different devices are connected by optical fiber, and the transmission method is illustrated by the IEC60044-8 communication protocol as an example; of course, the different units and / or different devices can also be connected by other methods, and the transmission method can also be transmitted through other communication protocols, which will not be explained one by one in the embodiments of the present application.

[0183] It can be seen that the battery module control unit 141 and the two energy storage valve control devices 11 in the embodiment of the present application are cross-redundantly connected, the power module control unit 151 and the two energy storage valve control devices 11 are cross-redundantly connected, the two energy storage valve control devices 11 and the two HVAC system control devices 13 are cross-redundantly connected, and the two energy storage valve control devices 11 are connected to each other, as well as the two HVAC system control devices 13 are connected to each other, realizing a dual-set redundant communication architecture for the linkage control of the energy storage valve control device 11, the battery module control device 14, the power module control device 15 and the HVAC system control device 13, which not only facilitates the unit expansion of the battery module control device 14 and the power module control device 15, but also enhances the reliability of the control system.

[0184] In some embodiments, based on the above embodiments, the following embodiments of the present application provide an illustrative introduction to the relevant content of "the energy storage valve control device 11 is configured to control the operating state of the energy storage valve according to the operating information".

[0185] For example, the operating information in the embodiments of the present application may include but is not limited to at least one of the following: equipment status information of the HVAC system, alarm information of the HVAC system, and environmental information of the energy storage valve during the operation of the HVAC system.

[0186] As another example, the operating information in the embodiments of the present application can be used to indicate at least one of the following: whether the HVAC system meets the preset abnormal operating conditions, whether the HVAC system meets the preset normal operating conditions, and whether the HVAC system meets the preset warning conditions.

[0187] In an embodiment of the present application, the energy storage valve control device 11 can determine the operating status of the HVAC system (for example, whether the preset abnormal operating conditions, preset normal operating conditions or preset warning conditions are met, etc.) based on the operating information of the HVAC system, and adaptively control the operating state of the energy storage valve according to the operating status of the HVAC system.

[0188] In one possible implementation, the energy storage valve control device in the embodiment of the present application can be configured as follows: if it is determined based on the operating information that the preset abnormal operating conditions are met, the energy storage valve is controlled to stop operating, so that when it is determined based on the operating information that the HVAC system has an operating abnormality, the energy storage valve can be controlled to stop operating, and the energy storage valve can be operated only in a safe temperature and humidity environment, so as to alleviate the safety problems caused by insulation failure due to condensation water on the surface of the cooling water pipe, thereby helping to improve the operating stability of the energy storage valve.

[0189] The preset abnormal operating conditions in the embodiment of the present application can be used to indicate that the HVAC system has the preset conditions for abnormal operation.

[0190] For example, the preset abnormal operating conditions in the embodiments of the present application may include, but are not limited to, at least one of the following:

[0191] Loss of air conditioning power supply in the HVAC system or phase sequence protection of the compressor main power supply;

[0192] The main and standby chillers in the HVAC system are both faulty, the main and standby combined air handling units are both faulty, or the main and standby water pumps are both faulty;

[0193] The water pump in the HVAC system is running, the water flow switch of the chiller is not actuated, and the pressure in the cold water pipe is lower than a first preset pressure threshold;

[0194] The HVAC system control equipment detects an alarm signal;

[0195] The temperature and humidity of the energy storage valve environment (or the energy storage valve hall indoor environment) rise and exceed the preset temperature and humidity threshold range;

[0196] Communication between the HVAC system control device and the energy storage valve control device is interrupted.

[0197] It should be understood that the temperature and humidity of the environment in which the energy storage valve is located in the embodiment of the present application can be detected by a low-level temperature and humidity sensor in the environment in which the energy storage valve is located, or can be obtained by other means, and this is not limited in the embodiment of the present application. It should be noted that, considering that the temperature and humidity of the environment in which the energy storage valve is located can tend to be stable after a certain period of time when the system is powered on, the embodiment of the present application can detect the temperature and humidity of the environment in which the energy storage valve is located when the system is powered on for more than a certain period of time (for example, 30 minutes).

[0198] For ease of understanding, in the following embodiments of this application, the operating information includes at least one of the equipment status information of the HVAC system, the alarm information of the HVAC system, and the environmental information of the energy storage valve during the operation of the HVAC system as an example, and an exemplary introduction is given to the relevant content of the energy storage valve control device determining the operating status of the HVAC system based on the operating information.

[0199] For example, if the equipment status information of the HVAC system is used to indicate that the water pump is running, the chiller water flow switch is not operating, and the cold water pipe pressure is lower than the first preset pressure threshold, the energy storage valve control device can determine that the preset abnormal operating conditions are met based on the equipment status information of the HVAC system, wherein the first preset pressure threshold may include but is not limited to 0.5 bar.

[0200] For another example, if the alarm information of the HVAC system is used to indicate the presence of a fire alarm signal, the energy storage valve control device can determine whether the preset abnormal operating conditions are met based on the alarm information of the HVAC system.

[0201] For another example, if the energy storage valve environmental information indicates that the temperature and humidity of the environment in which the energy storage valve is located continues to rise, exceeding a preset temperature and humidity threshold range, and showing no downward trend, the energy storage valve control device can determine based on the energy storage valve environmental information that a preset abnormal operating condition has been met. The preset temperature and humidity threshold range may refer to the temperature and humidity threshold range of the preset environmental process requirements of the energy storage valve hall. For example, the preset environmental process requirements may include, but are not limited to, a temperature of less than 30°C and a humidity of less than 43% RH.

[0202] It should be noted that the preset abnormal operating conditions involved in the above embodiments of the present application are exemplary introductions and may also include other abnormal conditions used to indicate that the HVAC system has abnormal operation, which will not be described one by one in the embodiments of the present application.

[0203] It can be seen that the HVAC system control device 13 in the embodiment of the present application can be a system for realizing temperature control and humidity control of the energy storage valve and / or the environment in which it is located. It can monitor in real time the loss of air-conditioning power supply, the phase sequence protection of the compressor main power supply, the inaction of the water flow switch and the low pressure of the cold water pipe, the continuous increase in temperature and humidity (or so-called temperature failure), and / or the fire alarm signal monitoring, etc., and send an early warning to the energy storage valve control device 11, so that the energy storage valve control device 11 can start from the mechanism of avoiding insulation failure caused by condensation water, and control the energy storage valve to stop running according to the operation information of the above-mentioned HVAC system sent by the HVAC system control device 13, thereby alleviating the safety problems caused by the insulation failure of the energy storage valve.

[0204] In summary, the energy storage valve control device in the embodiment of the present application can determine that the preset abnormal operating conditions are met and control the energy storage valve to stop operating when it is determined that there is an equipment failure (or system protection) in the HVAC system based on the equipment status information of the HVAC system, and / or the communication between the HVAC system control device and the energy storage valve control device is interrupted, or when it is determined that an alarm signal is detected based on the alarm information of the HVAC system, or when it is determined that the temperature and humidity of the environment in which the energy storage valve is located exceeds the preset temperature and humidity threshold range based on the energy storage valve environmental information. This allows the operating status of the energy storage valve to be adjusted in time when the HVAC system is unreliable, so that the energy storage valve can operate only in a safe temperature and humidity environment, thereby alleviating the safety problems caused by insulation failure due to condensation water on the surface of the cooling water pipe, which is conducive to improving the operating stability of the energy storage valve.

[0205] In another possible implementation, the energy storage valve control device in the embodiment of the present application can be configured as follows: if it is determined based on the operating information that the preset normal operating conditions are met, the energy storage valve is controlled to start operation, so that when it is determined based on the operating information that the HVAC system is operating normally, the energy storage valve can be controlled to start operation. When the HVAC system is reliable, the operating state of the energy storage valve can be adjusted in time so that the energy storage valve can operate in a safe temperature and humidity environment, thereby alleviating the safety problems caused by insulation failure due to condensation water on the surface of the cooling water pipe, which is conducive to improving the operating stability of the energy storage valve.

[0206] The preset normal operating conditions in the embodiment of the present application can be used to indicate that the HVAC system has the preset conditions for normal operation.

[0209] The HVAC system control equipment did not detect the alarm signal;

[0210] The temperature and humidity of the environment where the energy storage valve is located exceeds the preset temperature and humidity threshold for a period of time;

[0211] The communication between the HVAC system control device and the energy storage valve control device is normal.

[0212] For example, the preset time duration in the embodiment of the present application may include but is not limited to 5 minutes, and the preset temperature and humidity thresholds may include but are not limited to: a temperature threshold of 28° C. and a humidity threshold of 42% RH.

[0213] It should be noted that the preset normal operating conditions involved in the above embodiments of the present application are exemplary introductions and may also include other normal conditions for indicating that the HVAC system is operating normally, which will not be described one by one in the embodiments of the present application.

[0214] In some embodiments, based on the above embodiments and taking into account energy conservation and consumption reduction of the HVAC system, the energy storage valve control device in the embodiments of the present application can be configured to: obtain the operating mode of the energy storage valve and / or temperature information of each battery module in the energy storage valve, and send mode adjustment instruction information to the HVAC system control device based on the operating mode of the energy storage valve and / or the temperature information of each battery module in the energy storage valve. The mode adjustment instruction information can be used to instruct the HVAC system control device to adjust the operating mode of the HVAC system.

[0215] Correspondingly, the HVAC system control device may be further configured to obtain mode adjustment instruction information and adjust the operating mode of the HVAC system according to the mode adjustment instruction information. For example, the mode adjustment instruction information may include, but is not limited to, a control instruction, or the mode adjustment instruction information may include, but is not limited to, the operating mode of the energy storage valve and / or temperature information of each battery module in the energy storage valve.

[0216] The operating mode of the HVAC system in the embodiment of the present application may include but is not limited to a frequency reduction mode or a rated mode, wherein the power of the frequency reduction mode is less than the power of the rated mode.

[0217] In one possible implementation, if the mode adjustment indication information in the embodiment of the present application may include control instructions, the energy storage valve control device may be configured to: send control instructions to the HVAC system control device according to the operating mode of the energy storage valve and / or the temperature information of each battery module in the energy storage valve, wherein the control instructions are used to instruct the HVAC system control device to adjust the operating mode of the HVAC system.

[0218] Correspondingly, the HVAC system control device may be specifically configured to receive control instructions sent by the energy storage valve control device so as to adjust the operating mode of the HVAC system according to the control instructions. The control instructions may include but are not limited to frequency reduction control instructions or rated control instructions.

[0219] Optionally, the operating mode of the energy storage valve in the embodiment of the present application may include, but is not limited to, a zero power mode or a non-zero power mode. The non-zero power mode may include, but is not limited to, at least one of the following: a peak shaving and valley filling mode, a frequency modulation mode, an inertia support mode, a black start mode, an island power transmission mode, and a fault ride-through mode.

[0220] Exemplarily, the energy storage valve control device can be specifically configured as follows: if the temperature information is used to indicate that the temperature of each battery module falls within a preset temperature threshold range, and the operating mode of the energy storage valve is zero power mode (or no-load mode), then a frequency reduction control instruction is sent to the HVAC system control device, wherein the frequency reduction control instruction is used to instruct the operating mode of the HVAC system to be adjusted to the frequency reduction mode, so that the HVAC system control device can adjust the operating mode of the HVAC system to the frequency reduction mode according to the frequency reduction control instruction, thereby enabling the HVAC system to save energy and reduce consumption.

[0221] As another example, the energy storage valve control device can be specifically configured as follows: if the temperature information is used to indicate that the temperature of any battery module is higher than a first preset temperature threshold, or the operating mode of the energy storage valve is a non-zero power mode, then a rated control instruction is sent to the HVAC system control device, wherein the rated control instruction is used to instruct the operating mode of the HVAC system to be adjusted to the rated mode, so that the HVAC system control device can adjust the operating mode of the HVAC system to the rated mode according to the rated control instruction, so that the HVAC system can operate at full power, which is conducive to ensuring the suitability of the ambient temperature and humidity in which the energy storage valve is located.

[0222] In this implementation, the energy storage valve control device sends a control instruction to the HVAC system control device according to the operating status of the energy storage valve, so that the HVAC system control device can adjust the operating mode of the HVAC system according to the control instruction, thereby further realizing the linkage control of the energy storage valve control device and the HVAC system control device, so that when the operating status of the energy storage valve changes, the HVAC system control device can adjust the operating mode of the HVAC system in time, which not only enables the HVAC system to ensure that the temperature and humidity information of the operating environment during the operation of the energy storage valve meets the preset temperature and humidity requirements, thereby further improving the operating stability of the energy storage valve, but also helps to save energy and reduce consumption of the HVAC system.

[0223] In another possible implementation, if the mode adjustment indication information in the embodiment of the present application may include the operating mode of the energy storage valve and / or the temperature information of each battery module in the energy storage valve, the energy storage valve control device may be configured to: send the operating mode of the energy storage valve and / or the temperature information of each battery module in the energy storage valve to the HVAC system control device, wherein the operating mode of the energy storage valve and / or the temperature information of each battery module in the energy storage valve is used to instruct the HVAC system control device to adjust the operating mode of the HVAC system.

[0224] Correspondingly, the HVAC system control device may be specifically configured to receive the operating mode of the energy storage valve and / or the temperature information of each battery module in the energy storage valve sent by the energy storage valve control device.

[0225] Alternatively, the HVAC system control device may be specifically configured to receive the operating mode of the energy storage valve from the energy storage valve control device, and / or receive temperature information of each battery module in the energy storage valve from the battery module control device. Of course, the HVAC system control device may also obtain the temperature information of each battery module in the energy storage valve from other devices, for example, the HVAC system control device may receive temperature information of the corresponding battery module from a battery temperature acquisition unit.

[0226] In an embodiment of the present application, the HVAC system control device can adjust the operating mode of the HVAC system according to the operating mode of the energy storage valve and / or the temperature information of each battery module in the energy storage valve after obtaining the operating mode of the energy storage valve and / or the temperature information of each battery module in the energy storage valve.

[0227] For example, if the temperature information is used to indicate that the temperature of each battery module falls within a preset temperature threshold range, and the operation mode of the energy storage valve is zero power mode, the HVAC system control device can adjust the operation mode of the HVAC system to a frequency reduction mode, thereby enabling the HVAC system to save energy and reduce consumption.

[0228] As another example, if the temperature information indicates that the temperature of any battery module is higher than a first preset temperature threshold, or the operating mode of the energy storage valve is a non-zero power mode, the HVAC system control device may adjust the operating mode of the HVAC system to a rated mode, so that the HVAC system can operate at full power, thereby facilitating the suitability of the ambient temperature and humidity of the energy storage valve.

[0229] In this implementation, the HVAC system control device adjusts the operating mode of the HVAC system according to the acquired operating mode of the energy storage valve and / or the temperature information of each battery module in the energy storage valve, thereby further realizing the linkage control of the HVAC system control device and the energy storage valve control device or the battery module control device, etc., so that when the operating state of the energy storage valve changes, the HVAC system control device can timely adjust the operating mode of the HVAC system, which not only enables the HVAC system to make the temperature and humidity information of the operating environment during the operation of the energy storage valve meet the preset temperature and humidity requirements, thereby further improving the operating stability of the energy storage valve, but also helps to save energy and reduce consumption of the HVAC system.

[0230] In summary, in the embodiments of the present application, starting from the principle of energy saving and consumption reduction by the operation mode of the energy storage valve, by combining the temperature information of each battery module in the energy storage valve and / or the operation mode of the energy storage valve to perform strategic control to adjust the operation mode of the HVAC system to an appropriate operation mode, the linkage control of the HVAC system control device and the energy storage valve control device can be further realized, so that the HVAC system can not only ensure that the temperature and humidity information of the operating environment in which the energy storage valve is located during operation meets the preset temperature and humidity requirements, but also save energy and reduce consumption, thereby helping to improve the operating efficiency of the energy storage valve.

[0231] In some embodiments, based on the above embodiments, for ease of understanding, in the embodiments of the present application, the overall process of the energy storage valve control method is exemplarily introduced and explained by taking the energy storage valve control system using the structure shown in Figure 16 as an example. For example, the energy storage valve control device and the HVAC system control device in the embodiments of the present application both adopt a master-slave dual control device, adopt a cross-redundant connection for real-time communication, and adopt the above-mentioned master-slave switching logic to enhance the reliability of the energy storage valve control device and the HVAC system control device. It should be understood that when the energy storage valve is operating normally, the energy storage valve control device and the HVAC system control device are both operating normally, wherein the energy storage valve control device serves as the control center and the HVAC system control device serves as the auxiliary control.

[0232] FIG18 is a schematic diagram of the overall flow of the energy storage valve control method provided in some embodiments of the present application. As shown in FIG18 , the method of the embodiment of the present application may include the following steps:

[0233] 1) After the energy storage valve control device is started, the battery module control device monitors the temperature information of each battery module in the energy storage valve and sends it to the upper layer.

[0234] 2) The power module control device forwards the temperature information of each battery module to the energy storage valve control device.

[0235] 3) After the HVAC system control device is started, it detects whether the HVAC system meets the preset conditions for normal operation. The preset conditions can be called preset normal operating conditions.

[0236] 4) When the HVAC system meets the preset conditions for normal operation, the HVAC system control device may send a first communication signal to the energy storage valve control device to indicate that the HVAC system meets the preset conditions for normal operation.

[0237] 5) Upon receiving the first communication signal, the energy storage valve control device may control the energy storage valve to start operation.

[0238] 6) The HVAC system control device detects whether there is an equipment failure in the HVAC system (such as air conditioning tripping, etc.), and when it detects that there is an equipment failure in the HVAC system, it can send a second communication signal to the energy storage valve control device to indicate that there is an equipment failure in the HVAC system.

[0239] 7) The energy storage valve control device detects whether the cross-redundant communication with the HVAC system control device is interrupted, and when the cross-communication interruption is detected or the second communication signal is received, the energy storage valve can be controlled to stop operating.

[0240] 8a) When the energy storage valve is operating normally, the energy storage valve control device detects whether the preset frequency reduction conditions are met (for example, the temperature of each battery module is within the preset temperature threshold range, and the operation mode of the energy storage valve is zero power mode). If it is detected that the preset frequency reduction conditions are met, a frequency reduction control instruction can be sent to the HVAC system control device, so that the HVAC system control device adjusts the operation mode of the HVAC system to the frequency reduction mode.

[0241] 8b) When the energy storage valve is operating normally, the energy storage valve control device detects whether the preset rated conditions are met (such as the temperature of any battery module is higher than the first preset temperature threshold, or the operating mode of the energy storage valve is a non-zero power mode), and when it is detected that the preset rated conditions are met, it can send a rated control instruction to the HVAC system control device, so that the HVAC system control device adjusts the operating mode of the HVAC system to the rated mode.

[0242] In summary, in the embodiments of the present application, preventive and detection measures are added to address insulation failure in the energy storage valve. By connecting the HVAC system control device to the energy storage valve control device for linked control, strategic control can be implemented based on the mechanism of avoiding insulation failure caused by condensation, according to conditions such as HVAC system failure, temperature control failure, and / or communication interruption. This can alleviate the safety issues caused by insulation failure caused by condensation due to large deviations in ambient temperature and humidity, thereby improving the operational stability of the energy storage valve. In addition, by combining the temperature information of each battery module in the energy storage valve with the operating mode of the energy storage valve for strategic control, the HVAC system can ensure that the temperature and humidity information of the operating environment of the energy storage valve during operation meets the preset temperature and humidity requirements, while also saving energy and reducing consumption, thereby improving the operating efficiency of the energy storage valve.

[0243] It should be noted that the HVAC system control device in the embodiments of the present application can upload information to the energy storage valve control device, including but not limited to information on the master / standby status, communication status, self-test status, warning status, pre-set conditions for normal operation, and / or the presence of equipment failure, to facilitate system switching and HVAC linkage by the energy storage valve control device. Furthermore, the commands issued by the energy storage valve control device to the HVAC system control device may include but are not limited to frequency reduction control instructions, rated control instructions, communication status, and other information, to facilitate system switching and HVAC linkage by the HVAC system control device.

[0244] In addition, during normal system operation, if the primary and backup energy storage valve control devices experience an early warning, a communication failure with the HVAC system control device, or a communication failure between the primary and backup energy storage valve control devices, if the primary and backup energy storage valve control devices are inconsistent, or if a combined failure occurs, the primary energy storage valve control device may be used as the primary controller to start, stop, lock, unlock, and / or issue early warnings for the energy storage valve. If the primary and backup HVAC system control devices fail, a communication failure with the energy storage valve control device, or a communication failure between the primary and backup HVAC system control devices, if the primary and backup HVAC system control devices are inconsistent, or if a combined failure occurs, the primary HVAC system control device may be used as the primary controller to shut down the HVAC system, switch between the rated operating mode and the reduced-frequency operating mode, and / or issue early warnings.

[0245] In some embodiments, based on the above embodiments, the energy storage valve control device or HVAC system control device in the embodiments of the present application may also be configured as follows:

[0246] If the preset warning conditions are determined to be met based on the operating information, an alarm message will be output.

[0247] It should be understood that, when the energy storage valve control device or the HVAC system control device determines based on the operating information that a preset warning condition is met, it can output an alarm message to the corresponding monitoring device so that the operation and maintenance personnel can be notified of the alarm message in a timely manner. In addition, when the HVAC system control device determines based on the operating information that a preset warning condition is met, it can also output an alarm message to the energy storage valve control device so that the energy storage valve control device can determine that the HVAC system has an operating warning condition.

[0248] The preset warning conditions in the embodiment of the present application can be used to indicate that the HVAC system has the preset conditions that require an operation warning.

[0249] For example, the preset warning conditions in the embodiments of the present application may include, but are not limited to, at least one of the following:

[0250] There is a fault in some of the main and standby chillers in the HVAC system, a fault in some of the main and standby combined air handling units, a fault in some of the main and standby water pumps, or a fault in the constant pressure water supply device;

[0251] The pressure of the cold water pipe in the HVAC system is lower than the first preset pressure threshold or the pressure of the cold water pipe is higher than the second preset pressure threshold;

[0252] The liquid level in the make-up water tank in the HVAC system is lower than the preset level threshold;

[0253] During the cooling process of the chiller in the HVAC system, the cooling water temperature decreases at a rate less than a preset rate, and the cooling water temperature is higher than a second preset temperature threshold;

[0254] The voltage of one of the dual power supplies for air conditioning in the HVAC system falls within the preset voltage range.

[0255] For ease of understanding, in the following embodiments of this application, the operating information includes at least one of the equipment status information of the HVAC system, the alarm information of the HVAC system, and the environmental information of the energy storage valve during the operation of the HVAC system as an example to provide an exemplary introduction to the relevant content of determining the operating status of the HVAC system based on the operating information.

[0256] For example, if the equipment status information of the HVAC system is used to indicate that during the operation of the water pump, the pressure in the cold water pipe is lower than the first preset pressure threshold or the pressure in the cold water pipe is higher than the second preset pressure threshold, it can be determined based on the equipment status information whether the preset warning conditions are met; wherein, the first preset pressure threshold may include but is not limited to 0.5 bar, and the second preset pressure threshold may include but is not limited to 7 bar.

[0257] For another example, if the equipment status information of the HVAC system is used to indicate that during the cooling process of the chiller, the rate of decrease of the chilled water temperature is less than the preset rate, and the temperature of the chilled water is higher than the second preset temperature threshold, it can be determined based on the equipment status information that the preset warning conditions are met; wherein the second preset temperature threshold may include but is not limited to 5°C, or a temperature above 5°C.

[0258] It should be noted that the preset warning conditions involved in the above embodiments of the present application are exemplary introductions and may also include other warning conditions for indicating that the HVAC system needs to run a warning, which will not be described one by one in the embodiments of the present application.

[0259] It can be seen that the energy storage valve control device or HVAC system control device in the embodiment of the present application can output alarm information when it is determined based on the operating information that the preset warning conditions are met, so that the operation and maintenance personnel can inspect and repair the HVAC system in a timely manner without affecting the normal operation of the system.
