The design of the clean room establishes and maintains an environment with low environmental pollutants such as dust, air microorganisms, aerosol particles, and chemical steam. Designing a delicate environment like a clean room is not easy, but a step less than 10 steps will definitely define a simple way to help you and design it.
Most of the clean room manufacturers needed very strict conditions provided by the clean room. Clean rooms have complex mechanical frameworks, high development, work, and vitality costs, so it is very important to design a clean room in an appropriate and well -organized way. In the following procedure, the evaluation method and the design of the clean room, the flow of the people/materials in the factory, the classification of space, the space supply airflow, the space aircraft removal, the variables to be evaluated, the selection of mechanical systems, and heated. /Calculation/cooling load and support space requirements.
- People/Material Flow Evaluation Layout:
It is essential to evaluate the streaming of materials and people in a clean room suite. All important processes must be separated from the personnel access door or route. This is the largest solid source in the clean room, so it helps workers in the clean room.
Compared to the most important spaces, the CRITCAL space, which should have a single access to prevent space from becoming another space, requires a strategy. Some pharmaceutical and biopharmaceutical processes are more susceptible to mutual pollution from other drugs and bio -drug processes. It is necessary to carefully evaluate the separation of the material process, the inflow route of the raw materials, and the outflow route of the final product and the containment process.
- Organize the classification of space cleanliness:
It is very important to know what the particle performance requirements for the primary clinch classification standard and the particle performance requirements for each cleansing classification at the time of selection are. It is very important to know what the particle performance requirements for the primary clinch classification standard and the particle performance requirements for each cleansing classification at the time of selection are. There are particles of different particle tolerated particles provided by different cleaning (1, 10, 100, 1000, 10000, and 100000) and the Environmental Science and Technology Research Institute (IEST) standard 14644-1.
- Identify the pressure of the space:
Maintaining a positive airspace pressure in connection with denying dirt and tidy order space is a basis for preventing pollutants from entering clean rooms. If there is a uneven or negative space pressurization, it is very difficult to maintain the proper order of the space. What is the difference in space weight between spaces? Various examinations evaluated the penetration of contaminants to the difference in space weight between the difference in space weight between the clean room and the clean room, and the difference in space weight. These tests found a difference between 0.03 to 0.05 in W.G. It is possible to execute when the infiltration of pollutants is reduced. Space weight difference over 0.05 inches 0.05 inches W.G.
- Organize the supplying air flow of space:
Space cleanliness is a major variable in the decision of a clean room supply airflow. Looking at Table 3, each clean classification has a change in air. For example, a clean room with a class 100,000 has a 15-30 ACH range. The air replacement rate in the clean room must be taken into account the expected activities in the clean room. A class 100,000 (ISO 8) clean room with a low occupancy rate, low particle generation process, and a positive space pressurization associated with the cleanliness of adjacent dirt may use 15 Ach, but the same clean room is high. The occupancy rate, frequent traffic, high clean rooms require 30 Ach for particle generation processes, or pressurization in a neutral space.
- Identify the flow of air removal in the space.
Most of the clean rooms are positive, with electric outlets, optical equipment, windows outline, entrance/floor interface, division/roof interface, and improvised air removal. It causes expanding the air connected to the weight and improvised air removal space. Access entrance. It is important to understand that the room is not sealed and there is a leak. Around the fixed clean room, there is a 1 % to 2 % emission rate. Is this outflow terrible? not really.
- Identify the air balance of the space:
Most of the clean rooms are positive, with electric outlets, optical equipment, windows outline, entrance/floor interface, division/roof interface, and improvised air removal. It causes expanding the air connected to the weight and improvised air removal space. Alternating current
