What are the characteristics of clean laboratory design?

The determination of air cleanliness level in clean laboratory is based on product variety, production technology or use requirements. The specific clean room engineering design should be based on the requirements of the owner, product variety, production technology and production equipment, and the control granularity and cleanliness grade of the clean room are different.

Clean laboratory should try not to introduce or introduce particles (microorganisms), do not produce particles (microorganisms), and do not retain particles (microorganisms). The design and construction of clean room should realize the above three elements or three basic requirements. Various functional facilities of the clean room should adopt corresponding technical measures, such as reasonable plane layout, good people flow and logistics organization, and necessary personnel cleaning measures; The air flow should be reasonably organized in the clean air conditioning system, and various types of air filters, such as air pre-filtration, intermediate filtration and terminal filtration, should be installed. The whole system and its equipment should be well sealed. In the clean room building and its decoration, the structure, wall and ceiling materials and their connecting structures, doors and windows with satisfactory air tightness should be selected. Set up necessary technical measures and devices for cleaning, cleaning or disinfection and sterilization of clean rooms; Indoor pipes or devices should be concealed as far as possible or adopt structures that are not suitable for deposition and easy to clean.

The temperature, humidity and pressure of the clean room should be determined according to the production process or use requirements of the product. When designing a specific clean room, if the owner or production process has no special requirements, the design can be carried out according to the specified values of standards and specifications. What needs to be explained here is that the important difference between a clean room and a general air-conditioned room is that the clean room must maintain a certain pressure difference relative to the outdoor environment, non-clean room or the adjacent room of the clean room, and a certain pressure difference or negative pressure difference should be determined according to the production process or use requirements of the product. The design and construction of clean room is a comprehensive technology. According to the different uses of the clean room, it is necessary to set up different functional facilities, such as production technology and equipment, air purification, ventilation and air conditioning, clean building, electricity and lighting, fire control and safety, high-purity substance supply, environmental protection facilities, etc. Therefore, the close cooperation of various professional technologies is an important condition for the design and construction of clean room engineering.
