Description

[Technical Field]

[0001] The present invention relates to a method and system for designing a smoke-proof compartment. [Background technology]

[0002] There are buildings in which at least some of the partitions that separate the interior spaces are made of glass. When a fire breaks out in the interior spaces of such buildings, the glass breaks due to heat, and smoke leaks into other spaces adjacent to that interior space (smoke leakage), thereby reducing the safety of those other spaces.

[0003] In response to this, a system that sprays water onto glass windows has been proposed (see, for example, Patent Document 1). This system cools the glass windows by forming a water curtain by spraying water onto the glass windows from a spray head. In addition, forming a water curtain inside the glass windows blocks flames from outside the building. [Prior art documents] [Patent documents]

[0005] However, if there is a fire source between the spray head and the glass, the glass may heat up so much that it breaks before the spray head can activate. [Means for solving the problem]

[0006] A method for designing a smokeproof compartment that solves the above problem is a method for designing a smokeproof compartment in which a sprinkler system is placed in a space partitioned by a partition at least part of which is made up of glass, and the method estimates the heat generation rate of a fire source in the space, and uses the fire heat generation rate to set an allowable distance between the sprinkler system that sprays water on the glass section and the glass section, based on the height of the space from the fire source to the ceiling and the sprinkler system's water spray start temperature, where the allowable distance is set so that sprinkler system starts sprinkling water before the glass section is damaged, and determines the position of the sprinkler system so that the distance between the sprinkler system and the glass section is less than the allowable distance. [Effects of the Invention]

[0007] According to the present invention, when a fire breaks out in a space partitioned by a partition at least a portion of which is made of glass, it is possible to prevent the glass from breaking. [Brief explanation of the drawings]

[0009] (First embodiment) An embodiment of a method and system for designing a smoke-proof compartment will be described below. A smoke-proof compartment is a facility installed to prevent the spread of flames and smoke in the event of a fire, and includes a sprinkler system (also called a fire extinguishing system). The sprinkler system is, for example, a sprinkler. A sprinkler is a fire extinguishing system that has a sprinkler head installed on the ceiling or under the roof of a fire-protected object and automatically sprays water upon detecting the outbreak of a fire. The sprinkler system may be a water spray fire extinguishing system that sprays water from its spray head in droplets of 0.2 mm or less. Alternatively, the system may be a combination of a water spray fire extinguishing system and a sprinkler system.

[0010] FIG. 1 shows an example of a building 1 to which a smoke-proof compartment is applied. The building 1 has spaces 2 to 4. Space 4 is a vertical hole such as an evacuation stairwell, and is connected to space 3 (an attached stairwell) such as a corridor. Space 2 is a living room. Spaces 2 and 3 are separated by a partition 5. Part of the partition 5 is composed of a glass section 6 made from glass building materials. The glass section 6 may be a fixed wall or a movable fixture such as a door, shutter, or window. The glass section 6 may have a height from the floor 31 to the ceiling 7, or may have a height shorter than the height of the wall, such as a window.

[0011] As shown in FIG. 2 , sprinkler head 11 provided in sprinkler system 10 is provided on ceiling 7 of space 2. Sprinkler system 10 includes a water tank (not shown), a pump 12 connected to the water tank, water distribution pipe 13, sprinkler head 11, and a control panel 14. Sprinkler head 11 is equipped with a heat sensor. When the temperature detected by the heat sensor exceeds a threshold due to the occurrence of fire source 100 or the like, sprinkler head 11 outputs a command to start operation of sprinkler system 10 to control panel 14, which controls sprinkler system 10. Based on the command, control panel 14 drives pump 12 via a motor (not shown), thereby supplying water from the water tank to sprinkler head 11 via water distribution pipe 13. Sprinkler head 11 sprinkles water over a predetermined area.

[0012] When multiple sprinkler heads 11 are installed on the ceiling 7, each sprinkler head 11 must be installed so that the effective range of water spraying from one sprinkler head 11 overlaps with the effective range of an adjacent sprinkler head 11. The effective range is a circular area determined based on the effective water spray radius.

[0013] When combustible materials (such as desks, chairs, documents, and computers) placed near the glass portion 6 burn, the burning materials generate at least one of radiant heat and high-temperature hot air currents. The glass portion 6 heats up due to exposure to the radiant heat or hot air currents. The glass portion 6 breaks when the temperature difference between the high-temperature and low-temperature portions of the glass portion 6 becomes large. The temperature difference at which glass breaks is approximately 60°C to 100°C, depending on the thickness of the glass. Therefore, the glass portion 6 will break if it is heated too quickly. Furthermore, typical sprinkler systems 10 are activated by a heat sensor command when the temperature detected by the heat sensor falls below the glass-breaking temperature (e.g., around 80°C). However, if combustible materials are placed near the glass portion 6 and burn, the glass portion 6 may be heated so strongly that it breaks before sprinkling begins.

[0014] It is conceivable that by placing the sprinkler heads 11 close to the glass portion 6, cooling can be performed before the glass portion 6 breaks. However, it was unclear what distance between the sprinkler heads 11 and the glass portion 6 is necessary to prevent breakage of the glass portion 6. Depending on the building 1, it may be difficult to place the sprinkler heads 11 almost directly above the glass portion 6 due to structural reasons, etc. Furthermore, placing the sprinkler heads 11 almost directly above the glass portion 6 would mean densely placing the sprinkler heads 11 on the ceiling 7, which would increase costs. For this reason, the smokeproof compartment design system calculates the placement of the sprinkler heads 11 to spray water before the glass portion 6 breaks.

[0015] <Hardware configuration> The hardware configuration of the design system 15 will be described with reference to Fig. 3. The design system 15 is composed of an information processing device H10. The information processing device H10 includes a processor H11, a communication device H12, a storage device H13, an input device H14, and an output device H15. Note that this hardware configuration is an example, and it can also be realized by other hardware.

[0016] The storage device H13 (computer-readable medium) stores data and various programs for executing various functions. Examples of the storage device H13 include ROM, RAM, and a hard disk. The storage device H13 includes any available recording medium that can be accessed by a general-purpose or dedicated computer. The storage device H13 stores a design program and various data used to execute the program.

[0017] The processor H11 reads programs and data stored in the storage device H13 via the bus H17, etc., and performs control using these. Examples of the processor H11 include a CPU and an MPU. The processor H11 loads programs into RAM and executes various processes for each operation. The processor H11 is not limited to a processor that performs software processing for all of the operations it executes. For example, the processor H11 may be equipped with a dedicated hardware circuit (e.g., an application-specific integrated circuit: ASIC) that performs hardware processing for at least some of the operations it executes. That is, the processor H11 may be configured as any of the following:

[0018] [1] One or more processors H11 that operate according to a computer program (software) [2] One or more dedicated hardware circuits that perform at least some of the various processes [3] Circuits (circuits / circuitry) including combinations of these The communication device H12 is an interface that establishes a communication path with other devices via a network and transmits and receives data by wireless or wired communication. The input device H14 is a device used by a user to input commands to the processor H11, etc. The input device H14 is, for example, a touch panel, a keyboard, or a mouse. The output device H15 includes a display that displays calculation results, etc.

[0019] <Design system functions> The functions of the design system 15 will be described with reference to Fig. 4. The processor H11 executes a design program stored in the storage device H13, thereby providing the design system 15 with the following functions.

[0020] The design system 15 has an estimation unit 16, a distance setting unit 17, and an arrangement determination unit 18. The estimation unit 16, the distance setting unit 17, and the arrangement determination unit 18 constitute a control unit 21. The design system 15 also has a space information storage unit 19 and an equipment information storage unit 20. The space information storage unit 19 and the equipment information storage unit 20 are provided in a storage device H13. The design system 15 may be composed of multiple information processing devices H10. The space information storage unit 19 and the equipment information storage unit 20 may also be provided in a storage device H13 of an information processing device H10 other than the information processing device H10 that executes the design program.

[0021] The estimation unit 16 estimates the heat release rate of a fire source in a space. The distance setting unit 17 uses the fire source heat generation rate to determine the separation distance R between the sprinkler device 10 that sprays water on the glass part 6 and the glass part 6, based on the height of the space from the estimated fire source to the ceiling 7 and the sprinkler start temperature of the sprinkler device 10, which is the allowable separation distance at which sprinkling starts before the glass part 6 is damaged.

[0022] The position determination unit 18 determines the position of the sprinkler head 11 of the sprinkler system 10 so that the separation distance R between the sprinkler system 10 and the glass portion 6 is equal to or less than the allowable separation distance. For example, the separation distance R is the shortest horizontal distance between the surface of the glass portion 6 and the sprinkler head 11. Alternatively, the separation distance R may be the relative distance from the edge of the glass portion 6, the relative distance from the center of the glass portion 6, or the like.

[0023] Spatial information storage unit 19 stores spatial information. The spatial information includes the floor area, ceiling area, height from the floor to ceiling 7, and the position of glass section 6 of each of spaces 2 to 4 of building 1. The spatial information may also include the width of glass section 6, which is the length in the direction in which partition 5 extends. The spatial information may also include the position of sprinkler head 11, which is the result of design processing. The spatial information may also include BIM (Building Information Modeling) information, which creates a building model by combining three-dimensional objects such as pillars and walls.

[0024] Equipment information storage unit 20 stores equipment information. The equipment information includes the effective water sprinkling radius of sprinkler equipment 10 and the water sprinkling start temperature. The effective water sprinkling radius is information determined by the performance of sprinkler equipment 10. The effective water sprinkling radius determines the effective range 30 within which sprinkler head 11 can sprinkle water.

[0025] Design system 15 outputs to a display, which is output device H15, layout information 50 indicating the determined layout of sprinkler heads 11. A user of design system 15 confirms the layout drawing of sprinkler heads 11 based on layout information 50.

[0026] <How to design a smoke-proof compartment> A method for designing a smoke-proof compartment will be described with reference to Fig. 5. In this embodiment, a design method in which the design system 15 executes a design program will be described.

[0027] The distance setting unit 17 acquires space information from the space information storage unit 19 (step S1). The distance setting unit 17 also acquires facility information from the facility information storage unit 20 (step S2). The estimation unit 16 estimates the fire source heat generation rate (kW) (step S3). The fire source heat generation rate is the energy generated by the fire source per unit time. Here, the estimation unit 16 calculates the maximum fire source heat generation rate Qcrit. The maximum fire source heat generation rate Qcrit is the maximum heat generation rate at which the glass does not break. The maximum fire source heat generation rate Qcrit is calculated by experiment or the like.

[0028] Distance setting unit 17 calculates allowable separation distance Rcrit using maximum fire source heat generation rate Qcrit (step S4). Allowable separation distance Rcrit is the distance at which sprinkler system 10 can start spraying water before glass unit 6 is damaged when a fire source is present between glass unit 6 and sprinkler head 11. Also, allowable separation distance Rcrit is the relative distance in the horizontal direction between glass unit 6 installed in space 2 and the sprinkler head 11 closest to glass unit 6.

[0029] An example of a method for calculating the allowable clearance distance Rcrit is described in detail below. During a fire, the amount of heat generated by a fire source gradually increases over time. After a strong rising air current from the fire source reaches the ceiling 7, it disperses below the ceiling (ceiling jet). In situations where a ceiling jet is generated, it is known that the temperature of the glass section 6 also gradually increases as the fire source grows. For this reason, it is believed that there is a correlation between the temperature of the glass section 6 and the fire source heat generation rate Q. When calculating the allowable clearance distance Rcrit, the relationship between the temperature rise near the ceiling 7 exposed to the air current from the fire source at the maximum fire source heat generation rate Qcrit, the height of the space 2, and the clearance distance from the fire source to the sprinkler head 11 is calculated. This relationship is then used to calculate the clearance distance that will allow the sprinkler head 11 to begin operating at the maximum fire source heat generation rate Qcrit.

[0030] The ceiling flow temperature rise ΔT at a point separated by distance R from the fire source is expressed by the following equations (1A) and (1B) using the fire source heat release rate Q and the height H from the fire source to the ceiling 7 in space 2. The height H is determined using information contained in the spatial information. Separation distance R is the horizontal distance from the position of ceiling 7 directly above the fire source to any ceiling 7 or a position near ceiling 7.

[0033] The temperature rise value when the sprinkler system 10 is activated is defined as "ΔTsp." The temperature rise value ΔTsp is the value from a specified room temperature to the temperature at which the sprinkler system 10 starts sprinkling. When the sprinkler system 10 is activated at the maximum fire source heat generation rate Qcrit at which the glass does not break, the separation distance R must be set to satisfy the following equation (2). In equation (2), the above equation (1B) is used assuming that the ratio of the separation distance R to the height H exceeds 0.18. When the temperature rise value in space 2 due to the fire reaches or exceeds the temperature rise value ΔTsp, sprinkler system starts sprinkling.

[0036] Next, distance setting unit 17 calculates the separation distance R between glass portion 6 and the sprinkler heads 11 capable of spraying water onto glass portion 6, among the sprinkler heads 11 arranged in space 2 (step S6). Then, distance setting unit 17 determines whether separation distance R is equal to or less than allowable separation distance Rcrit (step S7).

[0037] Distance setting unit 17 determines whether separation distance R is equal to or less than allowable separation distance Rcrit (step S7). If distance setting unit 17 determines that separation distance R is equal to or less than allowable separation distance Rcrit (step S7: YES), it determines whether there is a watering obstruction and an unguarded area (step S8). Distance setting unit 17 determines that there is a watering obstruction if there is an obstacle within the effective watering radius. Information about the obstacle is included in the spatial information. Distance setting unit 17 also determines whether there is an area on the floor of space 2 that is not included in the effective watering radius of each watering head 11. If distance setting unit 17 determines that there is an area on the floor that is not included in the effective watering radius, it designates that area as an unguarded area.

[0038] If the distance setting unit 17 determines that there is no watering obstruction or unaltered portion (step S8: NO), the process ends. On the other hand, if distance setting unit 17 determines that separation distance R exceeds allowable separation distance Rcrit (step S7: NO), it adjusts the positions or number of sprinkler heads 11 (step S9). At this time, distance setting unit 17 positions sprinkler heads 11 that can spray water on glass portion 6 so that they are closer to glass portion 6.

[0039] After adjusting the position or number of sprinkler heads 11 in step S9, distance setting unit 17 returns to step S6 and repeats steps S6, S7, and S9 until separation distance R becomes equal to or less than the allowable separation distance Rcrit. In this way, sprinkler heads 11 are positioned taking into account the effective spray radius and such that separation distance R between glass portion 6 and sprinkler heads 11 becomes equal to or less than the allowable separation distance Rcrit.

[0040] <Actions and Effects of This Embodiment> As described above, according to the first embodiment, the following effects can be obtained. (1-1) According to the above embodiment, the design system 15 can estimate the allowable separation distance Rcrit at which water spraying can begin before the glass portion 6 breaks when a fire source is present between the sprinkler head 11 and the glass portion 6. The allowable separation distance Rcrit is the maximum distance that can prevent breakage of the glass portion 6, and can therefore be used as a standard for the appropriate separation distance R between the sprinkler head 11 and the glass portion 6. This prevents the sprinkler heads 11 from being placed at intervals shorter than necessary, thereby reducing costs, etc. Furthermore, breakage in the event of a fire can be prevented without using heat-resistant glass, etc., for the glass portion 6, thereby reducing costs, etc.

[0041] (1-2) According to the above embodiment, design system 15 estimates allowable separation distance Rcrit according to the height H of space 2 partitioned by glass portion 6. Design system 15 increases allowable separation distance Rcrit as the height H of space 2 decreases. This allows separation distance R between sprinkler head 11 and glass portion 6 to be set to an appropriate distance according to space 2.

[0042] Second Embodiment Next, a second embodiment of a method and system for designing a smoke-proof compartment will be described. In the second embodiment, the sprinkler head 11 is positioned using the procedure described in the first embodiment. The second embodiment also differs from the first embodiment in that an installation-prohibited area is set in which the installation of flammable materials is prohibited. Hereinafter, parts similar to those in the first embodiment will be assigned the same reference numerals, and detailed description thereof will be omitted.

[0043] Setting of an area where flammable objects cannot be installed will be described with reference to Figure 6. If flammable objects are placed near the glass section 6 and burn, the glass section 6 may be heated so strongly that it breaks before water can be sprayed. For this reason, an area where flammable objects cannot be installed is set near the glass section 6. Specifically, the design system 15 sets the flammable object installation prohibited area, which is provided along the glass section 6 and where flammable objects cannot be installed, to include sprinkler equipment 10 that sprays water on the glass section 6.

[0044] Distance setting unit 17 acquires the position and size of glass portion 6 from the spatial information (step S11). Distance setting unit 17 also acquires the position of the sprinkler head 11 closest to glass portion 6, among the sprinkler heads 11 whose placement has been determined (step S12). This position of sprinkler head 11 is the position determined in the first embodiment.

[0045] Then, distance setting unit 17 sets the area where installation of combustible objects is prohibited so as to include sprinkler head 11 (step S13). As shown in FIG. 7, installation-prohibited area 40 is a space having a height from floor 31 to ceiling 7. The length of installation-prohibited area 40 from sprinkler head 11 toward glass section 6 is equal to or less than allowable separation distance Rcrit. Furthermore, installation-prohibited area 40 has a width at least equal to or greater than the width of glass section 6. The interior materials of the portion of installation-prohibited area 40 facing the interior are made of flame-retardant materials. This makes it possible to prevent fires from breaking out in installation-prohibited area 40.

[0046] <Actions and Effects of This Embodiment> As described above, according to the second embodiment, in addition to the effects described in the first embodiment, the following effects can be obtained.

[0047] (2-1) In the above embodiment, the installation-prohibited area 40, which is provided along the glass portion 6 and in which the installation of flammable materials is prohibited, is set to include the sprinkler system 10 that sprinkles water on the glass portion 6. This makes it possible to design disaster prevention equipment that is less likely to damage the glass portion 6 in the event of a fire.

[0048] <Example of change> The above-described embodiments can be modified as follows: The embodiments and the following modifications can be combined with each other within the scope of technical compatibility.

[0049] (Design method) In each of the above embodiments, the estimation unit 16 calculated the maximum fire-source heat generation rate Qcrit to calculate the allowable separation distance Rcrit (step S1). Alternatively, the estimation unit 16 may calculate a fire-source heat generation rate Q that is smaller than the maximum fire-source heat generation rate Qcrit. For example, the estimation unit 16 may calculate a fire-source heat generation rate Q that is a predetermined percentage (e.g., 80%) of the maximum fire-source heat generation rate Qcrit.

[0050] In step S5 of positioning the sprinkler heads 11 based on the effective water spray radius, the distance setting unit 17 may position the sprinkler heads 11 that spray liquid onto the glass 6 at or below the permissible distance Rcrit from the glass 6. The distance setting unit 17 may then position other sprinkler heads 11 based on the sprinkler heads 11 that were installed based on the permissible distance Rcrit. For example, the distance setting unit 17 positions the sprinkler heads 11 so that the effective range 30 based on the effective water spray radius of one sprinkler head 11 overlaps with the effective range 30 of an adjacent sprinkler head 11.

[0051] In the above embodiments, the design system 15 designs the fire compartment according to a design program. Alternatively, the designer may design the fire compartment according to the above procedure without executing the design program.

[0052] In the first embodiment, the design system 15 generated the placement information 50 indicating the placement of the sprinkler heads 11. Alternatively, the person designing the fire compartment may determine the placement of the sprinkler heads 11 according to the procedure described above.

[0053] In the second embodiment, the design system 15 sets the installation-prohibited area 40, but the person who designs the fire compartment may set the installation-prohibited area 40. In the second embodiment, in addition to arranging the sprinkler heads 11 in the same manner as in the first embodiment, an installation-prohibited area 40 is set in which installation of flammable materials is prohibited. Alternatively, the installation-prohibited area 40 may be set, and then the sprinkler heads 11 may be positioned so that they are included in the installation-prohibited area 40.

[0054] "Height H" can be any distance from a specified height of the fire source to the ceiling. For example, "height H" can be the height from the tip of the fire source to the ceiling, using the predicted height of the fire source. Alternatively, for simplicity, "height H" can be the height from the floor (bottom of the fire source) to the ceiling.

[0055] (Watering equipment) According to the above-described embodiments, sprinkler system 10 is equipped with sprinkler head 11 having a heat sensor. Alternatively or additionally, sprinkler system 10 may be configured such that sprinkler head 11 and heat sensor are installed in different positions.

[0056] According to the above-described embodiments, the sprinkler system 10 is a sprinkler system, a water spray fire extinguishing system that sprays fine water droplets, or a combination of these. In addition, the sprinkler system 10 may be any system that can cool the glass portion 6 by emitting a substance, such as a foam fire extinguishing system, a halide fire extinguishing system, or a powder fire extinguishing system.

[0057] Next, the technical ideas that can be understood from the above-described embodiment and other examples will be described below. [A] The method for designing a smokeproof compartment according to claim 1, wherein the lower the water spray start temperature, the shorter the relative distance of the water spray equipment to the glass portion.
