Today, Jinan's small ventilation series tells everyone how to ventilate.

　　清潔通風

　　Clean and ventilate

　　這種方法更容易理解，也就是說，當項目的外部空氣沒有被有毒有害物質污染時，系統就會運行。

　　This method is easier to understand, that is, when the external air of the project is not polluted by toxic and harmful substances, the system will run.

　　隔離通風

　　Isolation ventilation

　　所謂隔離通風是指在工程隔離保護過程中實現內部循環通風的通風系統的運行方式。 隔離保護是一種民防工程保護方法，利用工程本身的防護能力和氣密性，防止有毒有害物質的空氣侵入工程中，危害工程人員的。

　　The so-called isolated ventilation refers to the operation mode of the ventilation system to achieve internal circulation ventilation in the process of Engineering isolation and protection. Isolation protection is a kind of civil defense engineering protection method, which uses the protection ability and air tightness of the project itself to prevent the air of toxic and harmful substances from invading the project and endangering the safety of engineering personnel.

　　出現以下任一情況時，該項目將轉移到隔離保護中：

　　The project will be transferred to isolation protection in case of any of the following conditions:

　　敵人對地面或襲擊初期的核生化武器襲擊的警告；

　　Warning of the enemy's attack on the ground or on nuclear, chemical or biological weapons at the beginning of the attack;

　　當項目外發生大面積火災時;

　　In case of large area fire outside the project;

　　在暴露于外部空氣的情況下，當過濾設備發生故障時；

　　In case of exposure to external air, in case of filter equipment failure;

　　通風孔被堵塞，通風已損壞。

　　The vent is blocked and damaged.

　　通風設備

　　Ventilation equipment price

　　過濾器通風（也稱為過濾器通風）

　　Filter ventilation (also known as filter ventilation)

　　所謂的過濾通風，是指工程外部的空氣被有毒有害物質污染，引入工程的空氣必須經過除塵處理后再分配到工程內部，用過的空氣必須排出。 通過超壓排氣系統。 項目的通風方式。

　　The so-called filtering ventilation refers to the air outside the project is polluted by toxic and harmful substances. The air introduced into the project must be dedusted and then distributed to the project interior, and the used air must be discharged. Through the overpressure exhaust system. Ventilation mode of the project.

　　當出現以下任何一種情況時，項目將轉移到過濾器通風系統中：

　　? items will be transferred to the filter ventilation system when any of the following occurs:

　　當項目需要形成一定的超壓值時，一些人員急需進入和退出項目；

　　When the project needs to form a certain overpressure value, some personnel urgently need to enter and exit the project;

　　當毒物沿著縫隙進入項目時，將威脅到項目內部人員的；

　　When poison enters the project along the gap, it will threaten the safety of personnel inside the project;

　　當項目隔離一段時間后，空氣中的CO2濃度會上升到規定的標準，并且人員難以維持。

　　When the project is isolated for a period of time, the CO2 concentration in the air will rise to the specified standard, and it is difficult for personnel to maintain.
