    对于大面积、集zhong和同时shi用或噪声控制和振动控制yan格清xi窒息,应shi用集zhong净hua空调系统。相反,可yishi用分散式空调系统。大型净hua车间还可yi结合shi用新风处li和分散式净hua空调装置。
    For large area, centralized and simultaneous use or noise control and vibration control strict cleaning asphyxia, centralized purification air conditioning system should be used. Instead, decentralized air conditioning systems can be used. Large scale purification workshop can also be combined with the use of fresh air treatment and decentralized purification air conditioning devices.
    dang需要满足洁净室、正空气量和pai气量de新风量时,空调系统应充分利用回风。只有在加gong过程zhong产生大量有hai物质时,才能shi用直流式空调系统,局bu处li不能保证卫生要qiu或损坏其他过程。
    When it is necessary to meet the requirements of clean room, positive air volume and fresh air volume, the air conditioning system should make full use of return air. Only when a large number of harmful substances are produced in the process of processing, the DC air conditioning system can be used. Local treatment can not guarantee the sanitary requirements or damage other processes.
    洁净室应在下列条件下dan独设置清洁空调系统:
    Clean rooms with separate air conditioning systems shall be provided under the following conditions:
    1.层流洁净室和湍流洁净室
    1. Laminar flow clean room and turbulence clean room
    2.mo端过滤qide不同洁净室
    2. Different cleanrooms for end filters
    3.洁净室和襤ua憧盏鱢ang
    3. Clean room and general air conditioning room
    4.运行班ci或shi用不同时间de洁净室
    4. Operating shifts or clean rooms with different times
    空气净huagong程
    5.dang洁净室面积过大或fang间过大时,应分为几个净hua空调系统,方便调整、回风管布置和风量、压li;
    5. When the clean room area is too large or the room is too large, it should be divided into several purification air conditioning systems to facilitate adjustment, return air duct layout, air volume and pressure;
    6.生产过程要qiu空调系统不能一起shi用。
    6. The production process requires that the air conditioning system cannot be used together.
    通常不jian议为空调系统安装xiao声qi。应采取其他综合cuo施,yi满足洁净室降噪de要qiu。dang必须shi用xiao声qi时,应shi用you不产生灰chenqie不易积聚de结gou制chengdexiao声qi和liang好de吸音材料。
    It is generally not recommended to install silencers 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-absorbing materials should be used.
    在洁净室zhong安装局bupai气系统应考虑yi下几点:
    The following points should be considered when installing local exhaust system in clean room:
    1。pai气系统不应穿过两个清洁空调系统;
    1。 The exhaust system should not pass through two clean air conditioning systems;
    2.局bupai气系统应采取cuo施fang止空气回流。zhong间pai放过滤qi或止回阀可yi安装在pai气系蚦heng稀Ⅻ/div>
    2. Measures shall be taken for local exhaust system to prevent air return. The intermediate discharge filter or check valve can be installed on the exhaust system.
    3.局bupai气系统应采取降噪cuo施。设置xiao声qi时,应将其放在风扇de吸气bu分上。
    3. Noise reduction measures should be taken for local exhaust system. When setting the muffler, it should be placed on the suction part of the fan.
    4.应注意有hai物謘hi膒ai放,shi其符合国jia规定depai放标准。空调系蚦hi衐e鼓风机、回风机和pai风机应互锁。联锁shun序如下:dang系统开qi时:首先打开鼓风机,然后将风扇和pai风扇驱回:dang系统关闭时:首先关闭pai气扇并返回风扇,然后关闭鼓风机。
    4. Attention should be paid to the emission of harmful substances to make them meet the national emission standards. The air blower, return fan and exhaust fan in the air conditioning system shall be interlocked. The interlock sequence is as follows: when the system is on: first turn on the blower, then drive the fan and exhaust fan back; when the system is off: first turn off the exhaust fan and return the fan, and then turn off the blower.
