Because the advantages that the micro-modular data center is convenient to set and the occupied area is adjustable, more and more data center industries choose to build the micro-modular data center, and as the data center with large occupied area and extremely high cost, a fire protection system of the micro-modular data center is always taken as a point needing to be considered emphatically when the data center is built. Referring to fig. 1, in the fire fighting measures of the micro-modular data center in the prior art, an independent fire fighting system is arranged in each micro-module, and specifically includes an automatic fire alarm 11, a gas discharge indicator 12, a gas fire-extinguishing emergency start-stop button 13 arranged on the micro-module 1, and a temperature detector 14, a smoke detector 15 and a fire-fighting steel cylinder cabinet 16 arranged in the micro-module 1; in the fire fighting operation, the automatic fire alarm 11 determines whether a fire occurs by receiving detection signals of the temperature detector 14 and the smoke detector 15, and controls a fire cylinder in the fire cylinder cabinet 16 to spray a gaseous extinguishing agent into the micromodule 1 when it is determined that a fire occurs. It can be known with reference to the three-view observation of the fire-fighting steel cylinder cabinet 16 in fig. 1, in the existing fire-fighting system, because the fire-fighting demand of a micro-module only needs to be guaranteed by the fire-fighting steel cylinder cabinet, so on the basis of considering the cost, the volume of the fire-fighting steel cylinder in the fire-fighting steel cylinder cabinet is smaller, the space utilization in the fire-fighting steel cylinder cabinet is not sufficient, because the setting of the fire-fighting steel cylinder cabinet needs to occupy a server cabinet in the micro-module, so that a micro-modular data center integrally has a very large cabinet space which is not fully utilized.

The fire extinguishing system of the micro-modular data center provided by the embodiment comprises: the smoke detector and the temperature detector are arranged on the first micromodule and the second micromodule, and the fire alarm controller and the fire-fighting steel cylinder cabinet are arranged in the first micromodule; a gas fire extinguishing agent steel cylinder is arranged in the fire-fighting steel cylinder cabinet, the gas fire extinguishing agent steel cylinder extends out of a gas outlet of the fire-fighting steel cylinder cabinet and is connected with a first port of a three-way pipe, a second port of the three-way pipe is connected with a first end of a first micromodule fire-fighting pipe, and a second end of the first micromodule fire-fighting pipe is positioned in the first micromodule; the third port of the three-way pipe is connected with the first end of the second micromodule fire fighting pipe, and the second end of the second micromodule fire fighting pipe is positioned in the second micromodule; the second end of the first micro-module fire fighting pipe and the second end of the second micro-module fire fighting pipe are provided with spray heads; the smoke detector is used for detecting whether smoke is generated in the micromodule in which the smoke detector is arranged, and the temperature detector is used for detecting the temperature in the micromodule in which the smoke detector is arranged; the fire alarm controller is used for judging whether a fire disaster occurs in the first micro module and the second micro module according to detection results of the smoke detector and the temperature detector, and when the first micro module and/or the second micro module are determined to have the fire disaster, the fire alarm controller controls a gas fire extinguishing agent steel cylinder in the fire-fighting steel cylinder cabinet to spray a gas fire extinguishing agent to enter the first micro module and the second micro module. It can be seen that the fire protection system of the micro-modular data center provided by the embodiment of the invention changes the structure of the whole micro-module data center, takes two micro-modules as an integral protection area for fire protection, a gas fire extinguishing agent steel cylinder capable of meeting the fire-fighting requirements of the two micromodules is arranged in one micromodule, because the fire-fighting requirements of the two micromodules need to be met, therefore, the volume of the gas fire extinguishing agent steel cylinder is larger than that of the fire extinguishing agent steel cylinder in the prior art, thereby fully utilizing the space of the fire extinguishing steel cylinder cabinet and further, because the fire-fighting requirements of two micromodules can be met by one fire-fighting steel cylinder cabinet and one gas fire extinguishing agent steel cylinder, therefore, two micro modules can be used for creating benefits by vacating a server cabinet, so that the purpose of fully utilizing the space of the server cabinet in the micro modules and further improving the utilization rate of the server cabinet in unit area while finishing the fire-fighting function of the micro modules is achieved.
Specifically, the following design idea of the scheme is provided based on the embodiment of the invention:
in view of the current situation of the traditional micro-module non-pipe network gas fire extinguishing system, the maximum volume of the steel cylinder which can be installed in 1 fire-fighting steel cylinder cabinet (600 mm wide, 1200mm long, 2200mm high) needs to be considered and fully utilized, so that the maximum space and the maximum medicament capacity which can be guaranteed are calculated; the maximum volume of the common non-pipe network steel cylinder in the market is 150L. Therefore, the volume of the gas fire extinguishing agent steel cylinder selected from the fire-fighting steel cylinder cabinet in the embodiment of the invention is 150L, and the fire extinguishing agent is heptafluoropropane (HFC-227ea) which is allowed to have a certain error in meeting the fire-fighting requirement; according to the existing design code of gas fire extinguishing systems (GB50370-2005), the fire extinguishing design dosage or inerting design dosage calculation formula of the protective area comprises the following steps:
W＝K×(V/S)×[C/(100-C)]
wherein W is the fire extinguishing design dosage or inerting design dosage (kg); c is the fire extinguishing design concentration or inerting design concentration (%); s is heptafluoropropane superheated steam with the temperature of 101kPa and the lowest environment temperature of a protection zoneSpecific volume (m) of3/kg); v is the guard net volume (M3); and K is an altitude correction coefficient.
Wherein, S ═ K1+K2×T
Wherein T is temperature (. degree. C.); k10.1269; k2Is 0.0005130.
Under the conditions that the temperature is 20 ℃, the altitude correction coefficient is 1, the fire extinguishing design concentration is 8 percent, and the steel cylinder is considered according to 150L, because the density of the gas fire extinguishing agent heptafluoropropane is similar to that of water, W is approximately 150kg, the maximum volume of 236m which can be guaranteed by a single steel cylinder can be calculated3。
According to the applicable scenario of the present invention, the width of the micromodule product is preferably not less than 4.2m, and the height (excluding the base region) is typically 2.8-3.2 m. Therefore, the length of the micromodule is 17-20m according to the calculated maximum guaranteed volume. Obviously, the micro-module is too long, is unfavorable from multiple aspects such as power supply, refrigeration, coupling with the building and the like, and is rarely applied.
Therefore, in the scheme provided by the embodiment of the invention, 1 gas fire extinguishing agent steel cylinder simultaneously ensures the left and right 2 micromodules. The protective volume of each micromodule is controlled to be 118m3Within. A standard 150L steel cylinder is provided with 1 tee joint in the middle, and a steel pipe and a spray head are led into a left micromodule and a right micromodule.
Of course, the volume of the micromodule will vary due to the volume of the fire extinguishing agent cylinder and the mass of the fire extinguishing agent, and since these three will change at any time, there is no particular limitation on these three, and the above data is presented only as a possible example.
In order to prevent the service equipment and the air conditioning equipment in the micro module from continuing to operate after a fire occurs, so as to prevent the fire from affecting fire extinguishing, optionally, as shown in fig. 2, when the fire alarm controller 24 determines that a fire occurs in the first micro module 20 and/or the second micro module 21, the fire alarm controller 24 is further configured to output a control signal to control the service equipment and the air conditioning equipment in the first micro module 20 and the second micro module 21 to stop operating.

Specifically, bleed light indicator 28 is positioned in a more prominent location and may also be positioned on fire alarm controller 24. The bleed light indicator 28 may also be used to indicate to the workers in the micromodule that a fire has occurred.
In order to prevent the gas extinguishing agent cylinder 26 in the fire-fighting cylinder cabinet from being controlled to spray the gas extinguishing agent in time due to the failure of the fire alarm controller 24, the fire-fighting system further comprises a manual/automatic change-over switch 01 and an emergency start-stop switch 02;

when the control state of the fire-fighting system of the micro-modular data center is a manual state, whether the gas fire-extinguishing agent steel cylinder 26 in the fire-fighting steel cylinder cabinet 25 sprays the gas fire-extinguishing agent or not is controlled by the emergency start-stop switch 02 after receiving user operation, namely, after the fire situation is judged by the staff of the data center, the gas fire-extinguishing agent steel cylinder 26 in the fire-fighting steel cylinder cabinet 25 sprays the gas fire-extinguishing agent by opening the emergency start-stop switch 02. It should be noted that the manual state is generally activated when a worker is present in the micromodule for a long time.
In order to prevent an unknown worker from entering the protected area after the fire extinguishing agent starts to be sprayed, the fire fighting system further includes a pressure sensor 03 disposed in the first and second micromodules and a protected area door lamp 04 disposed at an entrance of the protected area; the entrance of the guard zone is the entrance of the first micromodule 20 and the entrance of the second micromodule 21; at least two door lamps 04 in the protection area; the pressure sensor 03 detects the pressure in the first and second micro-modules 20 and 21 when the gas extinguishing agent cylinder 26 in the fire-fighting cylinder cabinet 25 emits the gas extinguishing agent and transmits the pressure detection result to the fire alarm controller 24; when the pressure detection result exceeds the preset pressure value, the fire alarm controller 24 controls the protection area door lamp 04 to flash according to the pressure detection result.
