Description

Fire alarm management device and method for containerized ESS

[0001] The present invention relates to a fire alarm management device and method for a containerized ESS, and more specifically, to a method for managing a fire alarm device provided inside a containerized ESS (Energy Storage System). Furthermore, the present invention relates to a fire alarm management device and method for a containerized ESS capable of establishing a fire management process in the event of a fire occurring inside the containerized ESS.

[0002] The Energy Storage System (ESS) business is considered a core business of the renewable energy era. Currently being rapidly commercialized, ESS is a system that improves power utilization efficiency by storing electricity and supplying it when needed. Through this, electricity from off-peak hours when rates are low or surplus electricity from renewable energy sources can be stored and used whenever required.

[0003] Meanwhile, containerized ESS is widely used due to the convenience of maintaining and managing the operating environment of energy storage systems from external variables, and accordingly, research has been continuously conducted to prepare for various accidents and improve operational efficiency.

[0004] For example, Korean Patent Publication No. 10-2024-0012248 discloses a fire-suppressing type ESS container that includes an installation space equipped with an Energy Storage System (ESS) and a fire-extinguishing space in which a fire-extinguishing liquid is stored, so as to be able to quickly and effectively suppress an electrical fire such as thermal runaway in an ESS, wherein when a fire occurs, a specific battery rack among the battery stacks constituting the ESS that has caught fire is moved to the fire-extinguishing space and submerged in the fire-extinguishing liquid to suppress the fire.

[0005] However, there is a disadvantage that efficient fire suppression cannot be performed because the fire suppression process involving the fan and damper is not properly applied when a fire occurs.

[0006] The objective of the present invention is to provide a fire alarm management device and method for a containerized ESS that can perform efficient fire suppression by establishing a process for managing a fire alarm provided inside a containerized ESS.

[0007] Another objective of the present invention is to provide a fire alarm management device and method for a containerized ESS that can increase the aerosol spraying efficiency by effectively controlling the operation of a fan and a damper when a fire occurs inside the containerized ESS.

[0008] A fire alarm management device for a containerized ESS according to the present invention may include an alarm device that generates an alarm, a fan / damper that performs fan On / Off and damper Open / Close, a Thermal Management System (TMS) that performs heating, ventilation, and cooling, an aerosol containing a smoke material for fire suppression, a programmable logic controller that generates control logic from a fire state, and a fire suppression control panel that controls the alarm device, the fan / damper, the TMS, and the aerosol based on the results of the programmable logic controller.

[0009] Here, the fan / damper can be a single integrated device or a separate, distinct device capable of performing fan On / Off and damper Open / Close.

[0010] Meanwhile, the fire control panel can generate a pre-fire alarm if smoke is detected by any one of at least two smoke detectors.

[0011] In addition, the fire control panel can detect smoke from at least two of the at least two smoke detectors, generate an alarm from the outside, or generate a fire alarm based on the output of the heat sensor and the hydrogen gas detector.

[0012] Here, a programmable logic controller can generate logic to control alarm devices, fans / dampers, TMS, and aerosols based on pre-fire alarms, fire alarms, aerosol spray conditions, and fire protection system errors.

[0013] Meanwhile, if no pre-fire alarm occurs, the fire control panel turns off the fan of the fan / damper and closes the damper, then returns to a normal state; however, if a pre-fire alarm occurs, it immediately turns on the fan of the fan / damper and opens the damper, and then determines whether a fire alarm has occurred after a certain period of time.

[0014] Here, if no fire alarm occurs, the fire control panel turns off the fan of the fan / damper, closes the damper, returns to a normal state, and transmits an event to the Energy Management System (EMS); if a fire alarm occurs, it turns off the fan of the fan / damper, closes the damper, activates the aerosol after a certain delay time, and then collects fire information after a certain waiting time.

[0015] At this time, the fire control panel can collect fire information, turn on the fan of the fan / damper and open the damper, and then transmit the event to the Energy Management System (EMS).

[0016] Here, the method by which the fire control panel collects fire information can determine whether a fire has occurred based on at least one of a decrease in injection pressure, a decrease in injection velocity, and a decrease in injection mass based on physical criteria.

[0017] In addition, the method by which the fire control panel collects fire information is based on visual criteria, and can determine whether a fire has occurred based on the visual confirmation of aerosol particles.

[0018] In addition, the method by which the fire control panel collects fire information is based on chemical criteria, and can determine whether a fire has occurred based on concentration detection.

[0019] In addition, the method by which the fire control panel collects fire information can determine whether a fire has occurred based on at least one of the depletion of the contents inside the can and the operating limit of the spray mechanism, based on mechanical criteria.

[0020] A fire alarm management method for a containerized ESS according to another embodiment of the present invention comprises: a sensor information collection step for collecting sensor information from a fire extinguishing control panel; a pre-fire alarm confirmation step for confirming a pre-fire alarm; a first fan off / damper close step for turning off the fan of a fan / damper and closing the damper and returning to the sensor information collection step if no pre-fire alarm occurs in the pre-fire alarm confirmation step; a first fan on / damper open step for immediately turning on the fan of a fan / damper and opening the damper if a pre-fire alarm occurs; a fire alarm confirmation step for determining a fire alarm after a certain period of time has elapsed following the execution of the first fan on / damper open step; a first fan off / damper close and event transmission step for turning off the fan of a fan / damper and closing the damper, returning to a normal state, and transmitting an event to an Energy Management System (EMS) if no fire alarm occurs; and a second step for turning off the fan of a fan / damper and closing the damper for a certain delay time if a fire alarm occurs. It may include a fan off / damper close step, an aerosol operation step for operating the aerosol after the second fan off / damper close step, a fire information collection step for collecting fire information after the release of the aerosol is finished, and a second fan on / damper open and event transmission step for turning on the fan of the fan / damper and opening the damper and transmitting an event to an energy management system during the fire information collection step.

[0021] Here, a pre-fire alarm may be triggered when smoke is detected by any one of at least two smoke detectors.

[0022] Additionally, a fire alarm may be triggered by detecting smoke in at least two of the two smoke detectors, by generating an alarm from the outside, or based on the output of a heat sensor and a hydrogen gas detector.

[0023] The fire alarm management device and method for a containerized ESS according to the present invention have the advantage of being able to perform efficient fire suppression by establishing a process for managing a fire alarm provided inside a containerized ESS.

[0024] In addition, the fire alarm management device and method for a containerized ESS according to the present invention has the advantage of effectively controlling the operation of a fan and damper when a fire occurs inside a containerized ESS, thereby increasing the aerosol spraying efficiency.

[0026] FIG. 2 is a flowchart illustrating a fire alarm management method for a containerized ESS according to an embodiment of the present invention.

[0027] Hereinafter, specific embodiments for implementing the present invention will be described with reference to the attached drawings.

[0028] In describing the present invention, terms such as first, second, etc. may be used to describe various components, but the components may not be limited by these terms. The terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component.

[0029] When it is described that a component is connected to or coupled with another component, it may be directly connected to or coupled with that other component, but it can also be understood that there may be other components in between.

[0030] The terms used in this specification are used merely to describe specific embodiments and are not intended to limit the invention. Singular expressions may include plural expressions unless the context clearly indicates otherwise.

[0031] In this specification, terms such as "comprising" or "having" are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not excluding in advance the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0032] In addition, the shapes and sizes of elements in the drawings may be exaggerated for clearer explanation.

[0033] Hereinafter, a fire alarm management device and method for a container-type ESS according to the present invention will be described in detail with reference to the attached drawings.

[0034]

[0035] FIG. 1 is a schematic diagram showing a fire alarm management device for a container-type ESS according to one embodiment of the present invention.

[0036] As can be seen in FIG. 1, the fire alarm management device for a containerized ESS consists of an alarm device (210) that generates an alarm, a fan / damper (220) that performs fan On / Off and damper Open / Close, a Thermal Management System (TMS) (230) that performs heating, ventilation, and cooling, an aerosol (240) that stores a smoke material for fire suppression, a programmable logic controller (250) that generates control logic from a fire state, and a fire suppression control panel (100) that controls the alarm device (210), fan / damper (220), TMS (230), and aerosol (240) based on the results of the programmable logic controller (250).

[0037] Here, the fan / damper (220) can be a single integrated device or a separate device capable of performing fan On / Off and damper Open / Close.

[0038] Additionally, the fire control panel (100) can generate a pre-fire alarm when smoke is detected by at least one of two smoke detectors when smoke is generated due to a temperature rise caused by a battery problem in a containerized ESS (battery energy storage systems).

[0039] In addition, smoke can be detected by two or more smoke detectors, an external alarm can be triggered, or a fire confirm alarm can be generated based on the output of a heat sensor and a hydrogen gas detector.

[0040] At this time, the programmable logic controller (250) generates logic to control the alarm device (210), fan / damper (220), TMS (230), and aerosol (240) based on the pre-fire alarm, fire alarm, spray state of the aerosol (240), and fire fighting system (FF System; Fire Fighting System) error.

[0041] Here, according to the logic output from the programmable logic controller (250), the fire extinguishing control panel (100) turns off the fan of the fan / damper (220) and closes the damper and returns to a normal state if no pre-fire alarm occurs, but if a pre-fire alarm occurs, it immediately turns on the fan of the fan / damper (220) and opens the damper, and then determines whether a fire alarm has occurred after a certain period of time.

[0042] At this time, if no fire alarm occurs, the fire control panel (100) turns off the fan of the fan / damper (220), closes the damper, returns to a normal state, and transmits an event to the Energy Management System (EMS); if a fire alarm occurs, it turns off the fan of the fan / damper (220), closes the damper, activates the aerosol (240) after a certain delay time, and then collects fire information after a certain waiting time.

[0043] Here, the fire control panel (100) can collect fire information, turn on the fan of the fan / damper (220), open the damper, and then transmit the event to the energy management system.

[0044] Conventionally, the logic was such that the fan / damper (220) unconditionally turned on the fan and opened the damper when a fire alarm was detected, and this resulted in the extinguishing effect of the aerosol (240) being reduced by half when the aerosol (240) was operating. In other words, conventionally, the extinguishing agent escaped to the outside due to the fan turning on and the damper opening, resulting in the blocking of air during a fire.

[0045] On the other hand, the fire alarm management device for a container-type ESS according to the present invention maximizes the extinguishing effect by the extinguishing agent by not operating the fan / damper (220) when the aerosol (240) is operating, and then appropriately operating the fan / damper (220) at the time when the aerosol (240) stops operating to maximize the extinguishing effect.

[0046] That is, the fire alarm management device for a container-type ESS according to the present invention can efficiently suppress fire by turning off the fan of the fan / damper (220) and closing the damper while the aerosol (240) is operating, thereby preventing the aerosol (240) from being released to the outside by the fan / damper (220).

[0047] In addition, by maximizing the fire extinguishing effect through ignition compared to conventional operating methods, the scope of ignition can be reduced in the event of a fire caused by ignition or explosion, and in some cases, it can be prevented in advance, thereby reducing the scope of maintenance and achieving cost savings.

[0048] Meanwhile, in the present invention, the method by which the fire control panel (100) collects fire information is determined by detecting it from various sensors, and can be determined based on physical criteria, visual criteria, chemical criteria, and mechanical criteria.

[0049] Physical criteria may include a reduction in injection pressure, injection velocity, and injection mass, while visual criteria may include the visual confirmation of aerosol particles. Additionally, chemical criteria may include concentration detection, and mechanical criteria may include the depletion of contents inside the can and the operating limits of the injection mechanism.

[0050] For example, a decrease in injection pressure can be checked as a physical criterion, specifically by using a pressure sensor to continuously monitor the injection pressure of the aerosol (240) and determining that the injection has ended when the internal pressure of the aerosol (240) drops below a specific value (e.g., ambient atmospheric pressure).

[0051] Additionally, a decrease in the spray speed can be confirmed, specifically through a device that measures mass change or spray speed at the discharge port of the aerosol (240) (an additional external device that can define when the spraying of the aerosol (240) has ended), and when the amount of aerosol (240) sprayed (amount released per unit time) decreases slightly and reaches a certain threshold (e.g., 0.1 mg / s), it can be determined that the spraying has ended.

[0052] Meanwhile, as a visual criterion, the end of the spraying can be determined when particles sprayed from the aerosol (240) are no longer visible through an optical device (laser scattering method, camera observation).

[0053] Additionally, as a chemical standard, based on equipment that measures the concentration of airborne particles in real time, such as an optical particle counter, if the concentration sprayed from the aerosol (240) decreases below a detection limit in a specific environment (e.g., a specific point inside a container), it can be determined that the spraying has ended.

[0054] Meanwhile, as a mechanical standard, the point at which the spraying stops when all the solution or gas inside the aerosol (240) is consumed can be determined by checking the mass change of the aerosol (240) or predicting it through fluid dynamic calculation of the internal contents, or the spraying can be determined when the nozzle of the aerosol (240) is clogged or the internal valve operation stops through monitoring the operation of the device.

[0055]

[0056] FIG. 2 is a flowchart illustrating a fire alarm management method for a containerized ESS according to an embodiment of the present invention.

[0057] As can be seen in FIG. 2, a fire alarm management method for a containerized ESS comprises a sensor information collection step (S100) for collecting sensor information from a fire extinguishing control panel (100), a pre-fire alarm verification step (S200) for verifying a pre-fire alarm, a first fan off / damper close step (S210) for turning off the fan of the fan / damper (220) and closing the damper if no pre-fire alarm occurs in the pre-fire alarm verification step (S200), and returning to the sensor information collection step (S100); a first fan on / damper open step (S300) for immediately turning on the fan of the fan / damper (220) and opening the damper if a pre-fire alarm occurs, a fire alarm verification step (S400) for determining a fire alarm after a certain period of time has elapsed following the execution of the first fan on / damper open step (S300), and if no fire alarm occurs, turning off the fan of the fan / damper (220) and closing the damper, and then normal It consists of a first fan off / damper close and event transmission step (S410) that returns to a state and transmits an event to an energy management system (EMS), a second fan off / damper close step (S500) that turns off the fan of the fan / damper (220) and closes the damper for a certain delay time when a fire alarm occurs, an aerosol operation step (S600) that operates the aerosol (240) after the second fan off / damper close step (S500), a fire information collection step (S700) that collects fire information after the discharge of the aerosol (240) is finished, and a second fan on / damper open and event transmission step (S800) that turns on the fan of the fan / damper (220) and opens the damper and transmits an event to an energy management system during the fire information collection step (S700).

[0058] Here, a pre-fire alarm may be triggered when smoke is detected by any one of at least two smoke detectors. Additionally, a fire alarm may be triggered when smoke is detected by at least two of the at least two smoke detectors, or by an external alarm, or based on the output of a heat sensor and a hydrogen gas detector.

[0059] Conventionally, the logic was such that the fan / damper (220) unconditionally turned on the fan and opened the damper when a fire alarm was detected, and this resulted in the extinguishing effect of the aerosol (240) being reduced by half when the aerosol (240) was operating. In other words, conventionally, the extinguishing agent escaped to the outside due to the fan turning on and the damper opening, resulting in the blocking of air during a fire.

[0060] On the other hand, the fire alarm management method for a container-type ESS according to the present invention maximizes the fire extinguishing effect by the fire extinguishing agent by not operating the fan / damper (220) when the aerosol (240) is operating, and then appropriately operating the fan / damper (220) at the time when the aerosol (240) stops operating to maximize the fire extinguishing effect.

[0061] That is, the fire alarm management method for a container-type ESS according to the present invention can efficiently suppress fire by turning off the fan of the fan / damper (220) and closing the damper while the aerosol (240) is operating, thereby preventing the aerosol (240) from being released to the outside by the fan / damper (220). In addition, by maximizing the fire extinguishing effect caused by ignition compared to conventional operating methods, the range of ignition can be reduced in the event of a fire caused by ignition / explosion, and in some cases, it can be prevented in advance, thereby reducing the scope of maintenance and achieving cost reduction.

[0062] Meanwhile, in the present invention, the method of collecting fire information in the fire information collection step (S700) is to detect and determine it using various sensors, and can be determined based on physical criteria, visual criteria, chemical criteria, and mechanical criteria.

[0063] Physical criteria may include a reduction in injection pressure, injection velocity, and injection mass, while visual criteria may include the visual confirmation of aerosol particles. Additionally, chemical criteria may include concentration detection, and mechanical criteria may include the depletion of contents inside the can and the operating limits of the injection mechanism.

[0064] Examples of using such physical, visual, chemical, and mechanical criteria have been explained in detail previously, so a further explanation is omitted.

[0065]

[0066] As described above, the fire alarm management device and method for a container-type ESS according to the present invention can perform efficient fire suppression by establishing a process for managing a fire alarm provided inside the container, and can increase the aerosol spraying efficiency by effectively controlling the operation of the fan and damper when a fire occurs inside the container.
