(1) The clean environment is for the service of the production process, clean room design must meet the environmental requirements of the production process, which is a matter of course. Therefore, in the clean room design of the production process on the environmental parameters of the requirements should be realistic, the area, layer height, temperature, humidity, cleanliness should be high high, the low low, the higher the better. In the production process does affect the normal operation of the premise as far as possible to reduce the parameter requirements, control the purification area, reduce the scope of high purification level clean area, strict control of the 100 level the higher level of unidirectional flow of the area of the clean area.

(2) as far as possible in the production process plan zoning the same level of clean room layout together, the cleanliness requirements of the process set up in the upwind side of the dust, toxic, hazardous, flammable, explosive gas production process equipment, containers as far as possible outside the clean zone, if you have to be placed in the clean zone should be as much as possible to take airtight measures to reduce the emission of dust exhaust gas.
