Laboratory airflow control speciality design requirements/实验室气流控制系统设计要求

In any case, air should always flow  the office, the corridor  axilary areas into the lab area.  all chemical laboratory exhaust gas should be directly dlscharged to the outslde,  mustn't be recycled.Therefore, unless chemical laboratory Is required to clean iselt, its relative to other space within a building maintains negative pressure of the camp.

在任何情况下,气流均应从办公室、走廊和辅助区域进入实验室区域,所有化学实验室排出的气体均应直接排故至室外,而不得循环利用。因此,除非化学实验室本身有洁净要求,否则其相对楼宇内其他空间,均应维持负压。

Experiment indoor arlow should be  low risk areas to high risk areas ,Generally spoaking. it should keep the flow of gas 47 lilers per second between the above area ( 170 cublc meters per hour ) Oftice areas in a Iaboratory should always maintaln a posltive pressure relative to the corridor  laboratory.

实验室内气流应从低危险区域流向高危险区域。一般来说,应维持上述区域之间47升/秒(即170立方米/小时)的气流量。实验室建筑的办公区域,应相对于走廊和实验室始终维持正压。

Under normal conditions, 6- 12 times every hour's room air changes are considered appropriate, When there is analysis equipment which is likely to produce high heat load  there is large local exhaust air in the room, there will be a need to increase in volume.

通常情况下,6-12次/小时的房间换气次数都被认为是合适的。当实验室内有可能产生高热负荷的分析设备,或房间内有较大量的局部排风时,则可能需要相应增大换气量。

The laboratory should adopt 100%full lresh air system, the central air supply unit  compensale laboratory exhaust demand.

实验室应采用100%全新凤系统,采用中央新风机组送风,并朴偿实验室排风需求。实验室排风不得循环利用于其它通风需求。

In order to ensure the safety of the staff, keep the distance of discharge point  flat roof at least 3 meters (ten feet)  oven higher in order to exhaust emissions  ellectively alluted.The specitic choice should be calculated to contim.

为保证人员的安全,应保持尾气排放点距离屋顶平面较高点至少3米(即10英尺),甚至可能要求更高,以便尾气有效地排放及稀释。具体选择应经过计算确认。

Interpretation of variable air volume speciality/解读变风量系统

In the large ventiation system, in order to solve the ventilation equipment at the end of the variable air volume demands  constant wind speed  to achieve further adjustment, we apply the frequency conversion  variable air volume ventilation control.

在大型通风系统中,为了解决通风设备末端的变风量要求和面风速恒定的要求,实现进一步调节。我们应用变频+蛮风量通风控制来解决。

Variable air volume control ventilation: Every country has strict requirements of the ventilation cabinet winds, For laboratory ventilation cabinet is the most important level of protecive equipment. Generally we shou Id always maintain constant ventilation counter wind speed of 0.5 m/s.Too high  too low surface wind speed can produce dangerous side leakage.

通风柜变风量控制:通风柜作为化学实验室内最重要的一级防护设备,各国对于通风柜的面风逮均有严格要求。通常要求始终维持通风柜面风速恒定为0.5m/s。过高或者过低的面风速。均会产生泄漏危险。

Local exhaust control:Cover cabinet. atomic absorption, reagent cabinets  some other local exhaust control should be able to continuously  effectively control  discharge the exhaust gases quickly  securely.

其他局部排风控制:对于万象抽气單、原子吸收罩、试剂柜等局部排风设施,应能够持续、高效地控制,安全迅速地将气体排出。

Room pressure control:Generally we should maIntaln negative pressure of the laboratory relative to that of the corrldor in order to avoid crass contamination of the office  production areas.

房间压力控制:通常情况下要求始路保持实验室相对于走廊的负压,以免对周围办公或生产区域造成交叉污染。

Reduce energy consumption:On the premise ofsatety, sIgntticantly reduce energy consumptlon, Including alr condtioning andtan energy consumption.

降低能耗:在充分满足安全的前提下,大幅降低运行能耗,包括空调以及风机能耗。
