(一) 濕式系統
（1） Wet system
1. 濕式系統工作原理：
1. Working principle of wet system:
火災發生的初期，建筑物的溫度隨之不斷上升，當溫度上升到以閉式噴頭溫感元件爆破或熔化脫落時，噴頭即自動噴水滅火。該系統結構簡單，使用方便、可靠，便于施工，容易管理，滅火速度快，控火效率高，比較經濟，適用范圍廣，占整個自動噴水滅火系統的75%以上，適合安裝在能用水滅火的建筑物、構筑物內。
In the early stages of a fire, the temperature of the building continues to rise. When the temperature rises to the point where the temperature sensing element of the closed nozzle explodes or melts off, the nozzle automatically sprays water to extinguish the fire. The system has a simple structure, is easy to use, reliable, easy to manage, has a fast fire extinguishing speed, high fire control efficiency, is relatively economical, and has a wide range of applications, accounting for more than 75% of the entire automatic sprinkler fire extinguishing system. It is suitable for installation in buildings and structures that can be extinguished with water.

2. Scope of use of wet systems:
在環境溫度不低于4℃、不高于70℃的建筑物和場所（不能用水撲救的建筑物和場所除外）都可以采用濕式系統。
Wet systems can be used in buildings and places with ambient temperatures not lower than 4 ℃ and not higher than 70 ℃ (excluding buildings and places that cannot be extinguished with water).

(二)干式系統
（2） Dry system
1.干式系統工作原理：
1. Working principle of dry system:
干式系統與濕式類似只是控制信號閥的結構和作用原理不同，配水管網與供水管間設置干式控制信號閥將它們隔開，而在配水管網中平時充滿著有壓力氣體用于系統的啟動。發生火災時，噴頭噴出氣體，致使管網中壓力降低，供水管道中的壓力水打開控制信號閥而進入配水管網，接著從噴頭噴出滅火。不過該系統需要多增設一套充氣設備，一次性投資高、平時管理較復雜、滅火速度較慢。
Dry systems are similar to wet systems, but the structure and working principle of the control signal valve are different. A dry control signal valve is installed between the water distribution network and the water supply pipe to separate them, while the water distribution network is usually filled with pressurized gas for system startup. When a fire occurs, the nozzle first sprays gas, causing a decrease in pressure in the pipeline network. The pressure water in the water supply pipeline opens the control signal valve and enters the water distribution network, and then sprays out from the nozzle to extinguish the fire. However, the system requires an additional set of inflation equipment, which incurs high one-time investment, complex daily management, and slow firefighting speed.
2.干式系統適用范圍：
2. Scope of application for dry systems:
干式系統適用于環境溫度低于4℃和高于70℃的建筑物和場所，如不采暖的地下車庫、冷庫等。
Dry systems are suitable for buildings and places with ambient temperatures below 4 ℃ and above 70 ℃, such as unheated underground garages, cold storage, etc.
3.干式系統特點：
3. Characteristics of dry system:
①. 不受環境溫度的制約，可用于一些無法使用濕式系統的場所。
① Not limited by ambient temperature, it can be used in places where wet systems cannot be used.
②. 比濕式系統投資高。因需充氣，增加了一套充氣設備而提高了系統造價。
② Higher investment than wet systems. Due to the need for inflation, an additional set of inflation equipment was added, which increased the system cost.
③. 施工和維護管理較復雜，對管道的氣密性有較嚴格的要求，管道平時氣壓應保持在一定的范圍，當氣壓下降到一定值時，就需要充氣。
③ Construction and maintenance management are complex, and there are strict requirements for the airtightness of pipelines. The pressure of pipelines should be maintained within a certain range during normal operation. When the pressure drops to a certain value, it needs to be inflated.
④. 比濕式系統噴水滅火速度慢，因為噴頭受熱開啟后，要排出管道中的氣體，然后再出水。
④ The fire extinguishing speed is slower than that of a wet system, because after the nozzle is heated and turned on, the gas in the pipeline needs to be discharged first, and then the water flows out.
