1.正壓送風(fēng)口應(yīng)用在電影院內(nèi)時：配電房通道的雜物應(yīng)該全部清理干凈，對報警系統(tǒng)部分損壞的零件必須進(jìn)行更換，樓梯口的正壓送風(fēng)口要安置妥當(dāng)，同時電影院應(yīng)增加一些應(yīng)急燈。

1 positive pressure air used in the cinema: distribution channel debris should clean all parts of the damaged, alarm system must be replaced, the stairs of the positive pressure air supply outlet to place at the same time, the cinema should increase the number of emergency lights.

2.正壓送風(fēng)口應(yīng)用在電腦機(jī)房內(nèi)時：可以保證機(jī)房內(nèi)換氣次數(shù),保證機(jī)房空氣參數(shù)。由空調(diào)送風(fēng)口從下面送入靜壓箱,靜壓箱寬度大于2-3倍空調(diào)送風(fēng)口尺寸，主機(jī)房內(nèi)部維持正壓不宜小于5Pa。

2. when the positive pressure air supply is applied in the computer room, it can guarantee the air change in the engine room and ensure the air parameters of the engine room. The air outlet from under static pressure box, static pressure box width is 2-3 times larger than the air outlet size, the host housing internal pressure to maintain not less than 5Pa.

3.正壓送風(fēng)口在建筑樓梯應(yīng)用時：在具體的工程設(shè)計上，相關(guān)消防設(shè)備應(yīng)包括建筑樓梯間全部正壓送風(fēng)口、著火層及上下相鄰層的排煙閥(口)、電動防火門、防火卷簾門等。消防控制系統(tǒng)無法聯(lián)動；未設(shè)置室外消防給水設(shè)施；電梯前室未設(shè)置正壓送風(fēng)口等火災(zāi)隱患，規(guī)范強(qiáng)調(diào)消防電梯前室正壓送風(fēng)，以提高前室風(fēng)壓的方法來達(dá)到阻止煙氣進(jìn)入的目的。

3 positive pressure air in the application of building stairs in concrete engineering design, fire protection equipment should include building. All the positive pressure air inlet, exhaust valve and ignition layer on adjacent layer (mouth), electric fire doors, fire shutter doors etc.. The fire control system can not be linked; outdoor fire water supply facilities are not set; the elevator is not set to send positive pressure air and other fire hazards, fire elevator room standard stressed the positive pressure air. In order to improve the method of anterior pressure to prevent smoke from entering the objective.
