  • 洁净工程选择空调净化系统应该从哪些方面着手?
    来源: 浏览: 发布日期:2020-07-07
    对于大面积、集中和同时使用或噪声控制和振动控制严格清洗窒息,应使用集中净化空调系统。相反,可以使用分散式空调系统。大型净化车间还可以结合使用新风处理和分散式净化空调装置。
    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.
    当需要满足洁净室、正空气量和排气量的新风量时,空调系统应充分利用回风。只有在加工过程中产生大量有害物质时,才能使用直流式空调系统,局部处理不能保证卫生要求或损坏其他过程。
    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单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.末端过滤器的不同洁净室
    2. Different cleanrooms for end filters
    3.洁净室和一般空调房
    3. Clean room and general air conditioning room
    4.运行班次或使用不同时间的洁净室
    4. Operating shifts or clean rooms with different times
    空气净化工程
    5.当洁净室面积过大或房间过大时,应分为几个净化空调系统,方便调整、回风管布置和风量、压力;
    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.生产过程要求空调系统不能一起使用。
    6. The production process requires that the air conditioning system cannot be used together.
    通常不建议为空调系统安装消声器。应采取其他综合措施,以满足洁净室降噪的要求。当必须使用消声器时,应使用由不产生灰尘且不易积聚的结构制成的消声器和良好的吸音材料。
    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.
    在洁净室中安装局部排气系统应考虑以下几点:
    The following points should be considered when installing local exhaust system in clean room:
    1。排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.局部排气系统应采取措施防止空气回流。中间排放过滤器或止回阀可以安装在排气系统上。
    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.局部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部分上。
    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.应注意有害物质的排放,使其符合国家规定的排放标准。空调系统中的鼓风机、回风机和排风机应互锁。联锁顺序如下:当系统开启时:首先打开鼓风机,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 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.
