(1) according to the categories, varieties or use of the products to be designed by the clean room purification project, the control objects and technical requirements of the clean room purification project are determined. As for the biological clean room decontamination, the control object is the dust particles in the air, microorganism; biological clean room of different products or use the decontamination, ask for containing air cleanliness, air microbial species and concentration, pressure and other requirements. As for clean room purification integrated circuit production engineering. Its main object is to control the dust particles in the air; according to the feature size of integrated circuit, the integration of different air cleanliness level, anti vibration and high pure material requirements are different, should put the concrete factory product variety determination.
(2) to ensure the cleanliness of the cleaning room air purification engineering must be within the clean room purification of various professional design involves the engineering design should adopt reliable technical measures properly, and to reduce or prevent indoor dust, reduce or prevent the growth of microorganisms, microbial particles or may cause cross contamination the material with clean room decontamination, effectively discharge the indoor microbial particles, to reduce or prevent them stranded in cleanroom purification engineering. Due to the cross contamination of dust particles or biological material brittle will endanger personal safety or rainfall products. Technical measures should be taken to prevent the safety and reliability of cross contamination, such as strict control of static pressure between different choice for clean room purification project, according to the requirements of a reasonable division of the clean air conditioning system and air system properly design.
(3) engineering design of clean room purification is a comprehensive design of the professional technology, especially the design of technological process design, clean room decontamination clean building design, air purification design and a variety of special requirements in close coordination, ear penetration and reasonable arrangement of the comprehensive design. Clean room purification engineering design should conform to the process (or use) process, reasonable selection of various types of equipment and device, try to achieve the smooth flow of people and goods, short flow pattern selection properly, the clean air conditioning system, a reasonable allocation of technical measures for a variety of special requirements properly, plane and space layout, clean workshop is reasonable, reliable clean workshop facilities the realization of economic operation.
(4) clean room purification engineering design should ensure safe production and meet the environmental protection requirements. The design of clean room purification project set slightly and facilities shall comply with the requirements of fire protection, fire prevention, should be designed according to the relevant standards, the state, because the clean room decontamination in the plane and space special walkway, buckled twists and turns and other characteristics, in the system design, the technical equipment and facilities the material sampling, with special attention required to choose to meet the requirements of the system, equipment and materials.
(5) with the development of science and technology, industrial upgrading of products very quickly, people are increasingly high demands on the quality of life, industrial clean room purification engineering, bio clean room purification engineering construction change rapidly, so the clean room purification engineering design itself has high technology, technology intensive and capital intensive characteristics, in order to improve purification of the project after the completion of the technical and economic benefits in the clean room, clean room purification engineering design should try to consider some flexibility, so as to make a clean room after the completion of the project can be purified with the development of science and technology * can easily adapt to technological innovation, product replacement or renewal of equipment requirements.
