The rooms designed by the purification engineering institute, regardless of the changes in external air standards, have the characteristics of maintaining the cleanliness level, temperature, humidity, and working pressure specified in the original settings. Air purification engineering is divided into vortex purification rooms and laminar flow purification rooms based on basic principles; Divided into industrial production purification engineering and microbial purification engineering according to application; The air cleaning process is a complete set of system software, which will be indicated in the design plan and construction acceptance specifications of the purification workshop. It roughly includes building decoration design system software for purification rooms, air conditioning purification system software, water system software, electrical system software, gas system software, etc. It supervises the temperature, environmental humidity, light intensity, cleanliness level, and static electricity phenomena in clean rooms, in order to achieve special processing process regulations.

净化工程自身是归属于企业的，它自身又分成市政工程基础设施建设基本建设及厂房装修基本建设及其医院门诊清洁卫生基本建设。归属于空气层面的工程。我企业的净化工程一般是基本建设净化室的工程项目。从装饰设计的视角看来，净化工程也归属于建筑装饰。

The purification project itself belongs to environmental protection enterprises, and it is divided into basic construction of municipal engineering infrastructure, basic construction of factory decoration, and basic construction of hospital outpatient cleaning and hygiene. Environmental engineering that belongs to the air level. Our company's purification engineering is generally a basic construction purification room project. From the perspective of decorative design, purification engineering also belongs to architectural decoration.

空气净化工程在提升 产品品质等层面有很明实际效果，据国外文献的报道，针对半导体材料在10000级和l00级净化室中生产制造的商品根据交流耐压试验，在l00级净化室和外环境空气中开展晶体三极管施胶外扩散，100级净化室中商品的特性遍布集中化，并且高值出現在更性能的地区。而在环境空气中的商品的特性极其分散化，特性也极不稳定。能够看得出，①是否空气清洁，商品良品率有非常大区别，②为了更好地提升 产品品质，不但生产制造商品的自然环境必须清洁，并且其重要的原料、调料的生产制造也应在清洁自然环境中开展。

Air purification engineering has shown the most practical effects in improving product quality and other aspects. According to reports from foreign literature, products manufactured in 10000 and 100 level purification rooms for semiconductor materials are subjected to AC voltage withstand tests, and external diffusion of crystal triodes is carried out in the 100 level purification room and external ambient air. The characteristics of products in the 100 level purification room are widely concentrated, and the highest value appears in areas with better performance. The characteristics of goods in the ambient air are extremely dispersed and unstable. It can be seen that ① there is a significant difference in the yield of goods based on whether the air is clean. ② In order to better improve product quality, not only must the natural environment for producing and manufacturing goods be clean, but the production and manufacturing of important raw materials and seasonings should also be carried out in a clean natural environment.
