Differential pressure control method and control requirements for clean rooms

Introduction A clean room is a room in which the concentration of suspended particles is controlled. For cleanrooms, maintaining their cleanliness levels is essential and is a requirement for cleanroom-related production activities. In general, the design, construction and operation of the clean room should minimize the interference and influence of the surrounding environment on the clean room space, and the differential pressure control is the most important to maintain the clean room cleanliness level, reduce external pollution and prevent cross-contamination. The most effective means. The static pressure difference in the clean room has the following effects: (1) When the doors and windows of the clean room are closed, the pollution of the surrounding environment is prevented from infiltrating into the clean room by the gap between the doors and windows. (2) When the clean room doors and windows are opened, ensure sufficient airflow speed, minimize the airflow of doors and windows and personnel entering the clean room, and ensure the airflow direction to minimize the ingress pollution. When clean indoor process production or activities make indoor air contain high-risk substances, such as high-sensitivity drugs such as penicillin, highly infectious high-risk viruses, bacteria, etc., the pressure difference of the clean room should be relatively negative. Domestic and foreign standards, norms [3], [4], [5], [6], [7], [8], [9] have specified the external pressure difference of the clean room, or give the differential pressure control Requirements and guidelines. This paper will discuss the requirements of clean room differential pressure control and discuss the method of clean room differential pressure control. a) Establishment of pressure difference in clean room The test and inspection of the clean room is the design and construction drawings of the construction unit according to the design unit. After all the ventilation and air-conditioning design is installed and in place, the sub-items are tested and measured separately for some projects, mainly air volume debugging and differential pressure debugging, cleanliness Test, measure the temperature and humidity of the clean room. (1) Air volume commissioning: According to the design and construction drawing design, the sending and returning pipelines are designed; the size of the design air volume is determined, the opening state of each pipeline returning air valve is determined, and the air volume of each branch is tested. This article is not covered here. (2) Cleanliness test: It is divided into test under air condition, test under static condition, and test under dynamic condition, and the content of dust in clean room is tested separately. Test under empty conditions means that the system (clean room) is in normal operation, but the process equipment and production personnel have not been tested. Test under static conditions means that the system (clean room) is in normal operation, the ...
