洁净室过滤器的顶部供气口根据出风口的具体布置而有所不同，包括：出口处仅具有高效过滤器的顶部供气口； 高效过滤器下方的铝板网顶部供气口; 高效过滤器下方是带有阻尼层的顶部供气口。 顶部送风的送风速度一般小于1m / s，扩散范围小，主要用于只要求净化的洁净室。 顶部供气应尽可能对称地居中放置在工作区域上方，并且顶部供气为正。 下部的清洁度高于送风口的边缘，局部布会严重降低工作区域的清洁度。 没有湍流，在顶部供气口上方的涡流区域将没有明显的灰尘颗粒。 保持高清洁度； 如果回风口的设计较小，并且工作台受到气流的阻碍，则沿壁的气流和涡流区将增加，污染面积将增加，清洁度将降低。
The top air supply port of the clean room filter is different according to the specific layout of the air outlet, including: the outlet only has the top air supply port of the high efficiency filter; the aluminum plate net top air supply port under the high efficiency filter; the top air supply port with damping layer is under the high efficiency filter. The velocity of top air supply is generally less than 1 m / s and the diffusion range is small. It is mainly used in clean rooms requiring only purification. The top air supply shall be symmetrically centered as far as possible over the working area and the top air supply shall be positive. The cleanliness of the lower part is higher than the edge of the air supply outlet, and the local cloth will seriously reduce the cleanliness of the working area. Without turbulence, there will be no visible dust particles in the vortex area above the top supply port. Maintain high-definition cleanliness; if the design of the air return port is small and the worktable is blocked by the air flow, the air flow and eddy current area along the wall will increase, the pollution area will increase, and the cleanliness will decrease.
侧面供气口是简单的供气口，其尺寸小于过滤器。 出风口通常设计为开放式或带有多层叶片。 回风口不应在上回风模式下使用； 净化空调的常用方式是：将一侧送回，将同一侧送回走廊，在另一侧返回类型，将下部送回，将双面送回 下。 侧流气流结构的计算是根据清洁度和换气次数进行的。 通常情况下，侧流气流组织的计算分为两种类型：等温射流和非等温射流。 在灰尘较小的情况下，始终希望清洁的气流能够充分发挥稀释作用。 因此，所连接的射流，即同一侧的回流结构是在同一侧返回空气，用于在再循环区域中设置工作区域。 中晶全球净化可以为洁净室和洁净室提供咨询，规划，设计，建造，安装和改造服务。
The side air supply port is a simple air supply port, whose size is smaller than the filter. Air outlets are usually designed to be open or with multiple blades. The air return outlet shall not be used in the upper air return mode; the common way of purification air conditioning is: return one side, return the same side to the corridor, return the other side, return the lower part, and return both sides to the lower part. The calculation of the side flow structure is based on the cleanliness and the number of air changes. Generally, there are two types of calculation of side flow: isothermal jet and non isothermal jet. In the case of small dust, it is always hoped that the clean air flow can give full play to the dilution effect. Therefore, the connected jet, i.e. the return structure on the same side, returns air on the same side, which is used to set the working area in the recycling area.

为了达到稀释污染的目的，有时要求过滤器出口的工作范围较大，并且可以选择扩散风口。 通常，扩散风口主要具有穿孔扩散风口，开缝狭缝扩散风口和单元型可调迎风口。 扩散器的空气扩散器的空气供应速度通常小于1m / s，并且主要应用于仅具有清洁要求的洁净室。 由于扩散出风口对整个房间的扩散范围较小，存在以下问题：气流扩散效果不明显，大部分送风气流直接在下方，洁净室呈死角。 在送风口之间或在出风口与壁之间。风口的单一分散布置易于形成气流的停滞区，从而降低了清洁度； 可以在送风口正下方直接形成较高速度的直接气流。 为了克服上述问题，通气孔通常沿着带状方向连续地布置，使得气流在平面方向上遍及整个分布。
In order to achieve the purpose of dilution pollution, it is sometimes required that the working range of the filter outlet is large, and the diffusion outlet can be selected. Generally, the diffusers mainly include perforated diffusers, slotted diffusers and unit type adjustable inlets. The air supply speed of the air diffuser of the diffuser is usually less than 1 m / s, and it is mainly used in the clean room with cleaning requirements only. Because the diffusion range of the diffused air outlet to the whole room is small, there are the following problems: the air diffusion effect is not obvious, most of the air supply flow is directly below, and the clean room presents a dead angle. Between air outlets or between air outlets and walls. The single dispersive arrangement of the tuyere is easy to form the stagnant area of the air flow, thus reducing the cleanliness; the direct air flow with higher speed can be directly formed directly under the air supply tuyere. In order to overcome the above problems, the vent holes are usually arranged continuously along the belt direction, so that the air flow is distributed throughout the whole plane direction.
当无尘室具有较高的净空并且需要顶部空气流动模式时，可以使用扩散器空气供应端口，扩散器空气供应也是扩散空气供应端口。 通过调节扩散器中间圆锥体的高度，气流以两种气流的形式（平坦或向下）发送。 感应净化空气供应口主要用于洁净室中产生烟雾的场合。 一次空气进入上喷雾室，该室中的压力由风压调节器调节，然后进入喉部空气供应室。 在喉咙入口处产生高速气流。 引导效果，导致室内空气从下方被吸入并与一次空气通过过滤器混合，然后送入室内； 风口过滤器通常采用低阻力，低电阻的中效或次效过滤的平层无纺布初级过滤器。 风口的阻力通常是具有节能，装置小等优点，并且出风口可将吸音材料粘贴在内部，引起降噪效果。
When the clean room has high clearance and the top air flow mode is required, the diffuser air supply port can be used, and the diffuser air supply is also the diffusion air supply port. By adjusting the height of the cone in the middle of the diffuser, the air flow is sent in two forms (flat or downward). The air supply port of induction purification is mainly used for the occasion of generating smoke in the clean room. Once the air enters the spray chamber, the pressure in the chamber is regulated by the air pressure regulator, and then enters the throat air supply room. Creates high-speed air flow at the throat entrance. The guiding effect causes the indoor air to be inhaled from below and mixed with the primary air through the filter, and then sent into the room; the air inlet filter usually adopts the flat non-woven primary filter with low resistance and low resistance and medium effect or secondary effect filtration. The resistance of tuyere usually has the advantages of energy saving and small device, and the tuyere can stick sound-absorbing material inside, causing noise reduction effect.
