Clean room decoration design layout is closely related to the purification air-conditioning system. The purification air-conditioning system should not only obey the overall layout of the building, but also conform to the principles of the purification air-conditioning system in order to give full play to the relevant functions. The designer of purified air conditioning should not only understand the layout of the building to consider the layout of the system, but also put forward requirements for the layout of the building to make it conform to the principle of clean room.
I. Plane layout of clean rooms
Clean room generally includes three parts: clean area, quasi-clean area and auxiliary area.
The layout of the clean room can be in the following ways:
Outer corridor surround type: Outer corridor can have windows and no windows, both for visiting and placing some equipment, some of them have on-duty heating in the outer corridor. The outer window must be double-sealed.
Inner corridor type: clean rooms are located in the periphery, while corridors are located in the interior. The cleanliness level of such corridors is generally higher, even the same level as clean rooms.
Two-end type: Clean area is set on one side, and quasi-clean and auxiliary rooms are set on the other side.
Core type: In order to save land and shorten pipelines, clean area can be the core, which is surrounded by various auxiliary rooms and concealed pipes. This way avoids the impact of outdoor climate on clean area, reduces the energy consumption of cold and heat, and is conducive to energy saving.
II. Personal Purification Route
In order to minimize the pollution caused by human activities in operation, people must change their clean clothes and blow, bathe and disinfect before entering the clean area. These measures are called "personal purification" for short "human purity". The room in which clean clothes are replaced should be provided with air supply, positive pressure should be maintained on the entrance side of other rooms, a little positive pressure should be maintained on toilets and showers, and negative pressure should be maintained on toilets and showers.

3. Material Purification Route
All kinds of objects must be purified before they are sent into the clean area, referred to as "material purification". Material purification route and human purification route should be separated. If material and personnel can only enter the clean room in the same place, they must also enter separately. Material is first treated by rough purification. When the production line is not strong, the intermediate storehouse can be set in the middle of the material line. If the production line is very strong, the direct material route is adopted. Sometimes, there are many purification and transmission facilities in the middle of the direct material route. In the system design, the coarse and fine purification stage of the material cleaning room will blow off many raw particles, so the relative clean area should maintain negative pressure or zero pressure, and if the pollution risk is high, it should also maintain negative pressure on the direction of the entrance.
IV. Pipeline Organization
The pipeline of clean room decoration design is very complex, so concealed organization is used for these pipelines. There are several specific ways of covert organization.
1. 技术实现 夹层
1. Technical interlayer
(1)顶部 技术实现 夹层。在这种夹层内一般因送、回风管的断面大，易于 作为夹层内起首揣摩的对象。一般将其安排在夹层的上方，其下安排电气管线。当这种夹层的底板可承受一定重量时，可以在上面设置过滤器及排风设备等。
(1) Top technical interlayer. In this kind of sandwich, the section of air supply and return pipe is the largest, so it is the first object to be considered in the sandwich. Generally, it is arranged at the top of the sandwich layer, and electrical pipelines are arranged below it. When the bottom plate of this sandwich can bear a certain weight, filters and exhaust equipment can be installed on it.
(2)客厅 技术实现 夹层。这种方式和只有顶部夹层相比，可以减少夹层的布线与高度，可以省去回风管道返回上夹层所需的 技术实现 夹道。在下夹道内还可设回风机动力设备配电等，某层洁净室的上夹道可以兼做上一层的下夹道。
(2) Interlayer of room technology. Compared with the top sandwich, this method can reduce the wiring and height of the sandwich and save the technical sandwich needed for the return air pipeline to return to the upper sandwich. In the lower chute, the power distribution of the power equipment of the return fan can also be set up, and the upper chute of a clean room can be used as both the upper and the lower chutes.
1. 技术实现 夹道(墙)
1. Technical Gateway (Wall)
上下夹层内的水平管线一般都要转向为竖向管线，这此竖向管线所在的隐蔽容量即 技术实现 夹道。 技术实现 夹道还可以放置不宜在洁净房间内部的一些辅助设备，甚至还可以作为一般回风管道或静压箱，有的可安设光管型散热器。这类 技术实现 夹道(墙)由于大多采取应用轻质隔断，以是当手工制作调整时，可方便地进行调整。
Horizontal pipelines in the upper and lower interlayers usually turn to vertical pipelines, which are the concealed space of the vertical pipelines, i.e. technical jackets. Technical chute can also be placed in some auxiliary equipment that is not suitable for clean rooms, or even as a general return air pipe or static pressure box, and some can be installed with light tube radiator. Because most of these technologies use light partition, they can be adjusted conveniently when the process is adjusted.
2. 技术实现 竖井
2. Technical Shaft
如果说 技术实现 夹道(墙)往往不越层，则需要越层时即用 技术实现 竖井，并且经常作为建筑结构的一部分，具有永久性。由于 技术实现 竖井把各层串通起来，为了防火，内部管线安装完成下，要在层间用耐火极限不低于楼板的质料封闭，检修work分层进行，检修门必须设防火门。不论 技术实现 夹层、 技术实现 夹道灰子 技术实现 竖井，当直接兼作风道时，其内表面必须按洁净室的内表面的要旨处理。
If the technical jacket (wall) often does not cross the floor, the technical shaft will be used when it needs to cross the floor, and it will be permanent as part of the building structure. Because the technical shaft links up all the layers, in order to prevent fire, after the installation of internal pipelines, the fire resistance limit between the layers should not be lower than that of the floor, and the overhaul work should be carried out in different layers, and the overhaul door must be equipped with fire doors. Whether it is a technical interlayer, a technical chute or a technical shaft, when it is directly used as an air duct, its inner surface must be treated according to the requirements of the inner surface of the clean room.
