    关于大面积、集中和同时运用或噪声控制和振动控制严厉清洗窒息,应运用集中净化空调系统。相反,能够运用分散式空调系统。大型净化车间还能够分离运用新风处置和分散式净化空调安装。
    Concentrated air-conditioning system should be used for cleaning asphyxia in large area, centralized and simultaneous operation or noise control and vibration control. Conversely, decentralized air conditioning systems can be used. Large-scale purification workshop can also separate fresh air disposal and decentralized purification air conditioning installation.
    当需求满足干净室、正空气量和排气量的新风量时,空调系统应充沛应用回风。只要在加工过程中产生大量有害物质时,才干运用直流式空调系统,部分处置不能保证卫生请求或损坏其他过程。干净室应在下列条件下单独设置清洁空调系统:
    When the demand meets the fresh air volume of clean room, positive air volume and exhaust volume, the air-conditioning system should make full use of the return air. As long as a large number of harmful substances are produced in the process of processing, DC air conditioning system can be used. Some disposal can not guarantee sanitary requests or damage other processes. Clean rooms should be separately equipped with clean air conditioning systems under the following conditions:
    1.层流干净室和湍流干净室;
    1. Laminar clean room and turbulent clean room;
    2.末端过滤器的不同干净室;
    2. Different clean rooms for end filters;
    3.干净室和普通空调房;
    3. Clean room and general air-conditioning room;
    4.运转班次或运用不同时间的干净室;
    4. Running shifts or using clean rooms at different times;
    5.当干净室面积过大或房间过大时,应分为几个净化空调系统,便当调整、回风管布置微风量、压力;
    5. When the area of clean room is too large or the room is too large, it should be divided into several purification air-conditioning systems, which can be adjusted conveniently, and the return air duct is arranged with light air volume and pressure.

    6.消费过程请求空调系统不能一同运用。通常不倡议为空调系统装置消声器。应采取其他综合措施,以满足干净室降噪的请求。当必需运用消声器时,应运用由不产生灰尘且不易积聚的构造制成的消声器和良好的吸音资料。
    6. Consumption process requests that air conditioning systems cannot be used together. Mufflers are not usually recommended for air conditioning systems. Other comprehensive measures should be taken to meet the requirements of noise reduction in clean rooms. When it is necessary to use mufflers, mufflers made of structures that do not produce dust and are not easy to accumulate and good sound absorption materials should be used.
    在干净室中装置部分排气系统应思索以下几点:
    The following points should be considered when installing part of the exhaust system in the clean room:
    1。排气系统不应穿过两个清洁空调系统;
    1. Exhaust system should not pass through two clean air conditioning systems.
    2.部分排气系统应采取措施避免空气回流。中间排放过滤器或止回阀能够装置在排气系统上。
    2. Some exhaust systems should take measures to avoid air reflux. Intermediate discharge filters or check valves can be installed in the exhaust system.
    3.部分排气系统应采取降噪措施。设置消声器时,应将其放在风扇的吸气局部上。
    3. Some exhaust systems should adopt noise reduction measures. When the muffler is installed, it should be placed on the suction part of the fan.
    4.应留意有害物质的排放,使其契合国度规则的排放规范。空调系统中的鼓风机、回风机和排风机应互锁。联锁次第如下:当系统开启时:首先翻开鼓风机,然后将风扇和排风扇驱回:当系统关闭时:首先关闭排气扇并返回风扇,然后关闭鼓风机。
    4. Attention should be paid to the emission of hazardous substances so as to conform to the emission standards of national rules. Blowers, return fans and exhaust fans in air conditioning systems should be interlocked. The interlocking order is as follows: when the system is open, first turn on the blower, then drive the fan and exhaust fan back: when the system is closed, first close the exhaust fan and return to the fan, then close the blower.
