General Regulations And Standards for Clean Room Air Purification

Clean Rooms, as specialized production environments, require air purification systems that are critical for maintaining internal cleanliness, ensuring product quality, and ensuring production efficiency. The design, operation, and maintenance of air purification systems should follow a set of general regulations and standards in order to assure the good performance of the air purification systems that, in turn, reject the airborne particulate matter, microorganisms, and others and confine themselves to the ample requirements of production processes in the sense of air cleanliness. This paper will outline the overall principles of Cleanroom Air Purification, and the paper will hope to serve as a valuable guide to the practitioners working in the related areas.

Air Purification System Design

• System Layout: Air purification systems must be rationally organized regarding the Clean Room Layout, production processes, and cleanliness conditions. The system must also make sure that the air enters the environment with higher ranks of cleanliness to the lower ranks of cleanliness, the same case must be true outwards.

• Air Flow: Good air flow should be maintained within the cleanroom to ensure even air distribution and remove generated contaminants. Proper airflow organization can effectively improve air purification efficiency and reduce dead spots and vortexes.

• Filter Selection: To support the demands of various degrees of cleanliness, the air purification system ought to employ high-efficiency, low-resistance filters. Particulars that should be taken into consideration when selecting filters include the nature, concentration, and size of particle matter.

• Air Handling Equipment: Depending on the production process requirements, the air purification system may include humidification, dehumidification, heating, cooling, and other treatment equipment. These devices should be selected and configured according to actual needs to ensure that air parameters meet production requirements.

Air Purification System Operation

• System Operating Parameters: The air purifying system would be adjusted to optimal operation parameters like air volume, temperature, and humidity in order to control air cleanliness and comfort. These parameters must be modified accordingly according to production processes and variations in the seasons.

• System Monitoring: Cleanrooms should establish a comprehensive air purification system monitoring mechanism to monitor key parameters such as air cleanliness, temperature, and humidity in real time. The monitoring system should include an alarm function to promptly detect and address abnormalities.

• Operation Records: Detailed records should be kept of the air purification system's operating status, including air volume, temperature, humidity, and filter replacement status. These records facilitate system performance analysis, identification of potential issues, and optimization of operational strategies.

Air Purification System Maintenance

• Filter Replacement: Filters are core components of air purification systems and should be replaced regularly based on actual conditions. The filter replacement cycle should be determined based on factors such as particulate matter concentration, properties, and age.

• Equipment Maintenance: All equipment in the air purification system should be regularly maintained, including cleaning, inspection, and adjustments. Equipment maintenance should ensure proper operation and stable performance.

• System Cleaning: Cleanroom air purification systems should be cleaned regularly to remove accumulated dust and contaminants. System cleaning should be performed according to cleanliness levels and production process requirements to avoid disrupting production.

Air Purification System Performance Evaluation

• Cleanliness Testing: Cleanrooms should regularly conduct cleanliness testing to assess the performance of the air purification system. Test results should be compared with the cleanliness level required by the production process to ensure compliance.

• Particle Counting: Particle counting is an important method for evaluating air purification effectiveness. Using a particle counter to count airborne particles provides insights into the system's removal efficiency and performance stability.

• Microbial Monitoring: For certain production processes sensitive to microorganisms, air purification systems should also undergo microbial monitoring. Regularly collecting air samples for microbial culture and analysis can assess the system's effectiveness in removing microorganisms.

Air Purification System Improvement and Optimization

• Technology Upgrade: With the continuous advancement of science and technology, air purification technology is also constantly evolving. Cleanrooms should monitor the development of new technologies and equipment, and timely upgrade and replace them to improve air purification efficiency and quality.

• Operational Optimization: By analyzing and studying air purification system operating data, deficiencies and problems in system operation can be identified. Operational optimization includes adjusting operating parameters, optimizing airflow distribution, and improving equipment configuration to enhance system performance and stability.

• Management Innovation: Cleanrooms should continuously improve the management system and operating procedures for air purification systems, strengthen personnel training and management, and enhance system operation and maintenance quality.

Conclusion

Air purification systems in cleanrooms play an important role in the quality of the internal air, the product, and also the effectiveness of production. It is extremely important to follow the general design, operational, and maintenance regulations and standards to maintain consistent performance of the entire system and successful combating of pollutants.
