氣體滅火系統一般由滅火劑儲存裝置、啟動分配裝置、輸送釋放裝置、監控裝置等組成。那么你知道氣體滅火系統的防護區要求是什么嗎？

　　Gas fire extinguishing system generally consists of extinguishing agent storage device, starting and distributing device, conveying and releasing device, monitoring device and so on. Do you know what the containment requirements are for a gas fire extinguishing system?

　　防護區宜以單個封閉空間劃分；同一區間的吊和地板下需同時保護時，可合為一個防護區；采用管網滅火系統時，一個防護區的面積不宜大于800㎡，且容積不宜大于3600m;采用預制滅火系統時，一個防護區的面積不宜大于500㎡，且容積不宜大于1600m。

　　The protected area should be divided into a single enclosed space. When the suspended ceiling layer and the floor under the same zone need to be protected at the same time, it can be combined into a protection zone; When using pipe network fire extinguishing system, the area of a protection area should not be more than 800 square meters, and the volume should not be more than 3600m; When using prefabricated fire extinguishing system, the area of a protection area should not be more than 500 square meters, and the volume should not be more than 1600m.

　　防護區圍護結構及門窗的耐火極限均不宜低于0.5h；吊頂的耐火極限不宜低于0.25h。防護區圍護結構承受內壓的允許壓強，不宜低于1200Pa。防護區應設置泄壓口，宜設在外墻上。七氟丙烷滅火系統和二氧化碳氣體滅火系統的泄壓口應位于防護區凈高的2/3以上。

　　The fire resistance limit of the enclosure structure and doors and Windows in the protection area should not be less than 0.5h; The fire resistance limit of the ceiling should not be less than 0.25h. The allowable pressure of the enclosure structure of the protection area under internal pressure should not be less than 1200Pa. The protection area should be equipped with a pressure relief port, which should be located on the outer wall. The pressure relief port of HFc-227ea fire extinguishing system and CARBON dioxide gas fire extinguishing system should be located at least 2/3 of the net height of the protected area.

　　噴放滅火劑前，防護區內除泄壓口外的開口應能自行關閉。防護區的環境溫度不應低于-10℃。防護區用的通風機和通風管道中的防火閥，在噴放二氧化碳前應自動關閉。

　　Before spraying the extinguishing agent, all openings in the protected area, except the pressure relief outlet, should be closed by themselves. The ambient temperature in the zone should not be lower than -10 ° C. The fire valve in the ventilator and ventilation pipe used in the protection area should be closed automatically before spraying carbon dioxide.

　　采用全淹沒二氧化碳川消滅火系統的防護區，應符合下列規定：對氣體、液體、電氣火災和固體表面火災，在噴放二氧化碳前不能自動關閉的開口，其面積不應大于防護區總內表面積的3%，且開口不應設在底面。對固體深位火災，除泄壓口以外的開口，在噴放二氧化碳前應自動關閉。等等。

　　For gas, liquid, electrical and solid surface fires, openings that cannot be closed automatically before carbon dioxide is discharged shall not exceed 3% of the total internal surface area of the protected area, and openings shall not be located on the underside. For solid deep fire, except for the pressure relief mouth, the opening should be automatically closed before spraying carbon dioxide. And so on.
