A cleanroom, also known as a cleanroom, is a room designed to remove airborne pollutants, harmful air, and bacteria within a specific space. It also controls indoor temperature, cleanliness, pressure, air velocity, airflow distribution, noise, vibration, lighting, and static electricity within specified limits.
To ensure the air cleanliness requirements of cleanrooms for production environments or other purposes, several comprehensive technical measures must be implemented:
1. Use production processes and equipment that generate fewer pollutants.
2. Take necessary measures to isolate negative pressure to prevent the spread of pollutants generated during the production process.
3. Reduce the amount of pollutants introduced into the room by personnel and materials.
4. Strengthen cleanroom management and conduct cleaning and disinfection according to regulations.
5. Ensure that personnel and materials are properly managed, preventing the crosstalk between personnel and material flows.
In addition to the above measures, the most important technical measures for cleanrooms are:
The cleanroom distributes a sufficient amount of treated clean air through appropriate equipment to replace or dilute pollutants generated during normal operation, while simultaneously removing pollutants from the room. This is the fundamental principle of air purification.
Specifically, the air purification process in a cleanroom is based on the different cleanliness levels required for the room. The treated air is distributed in different ways, with corresponding carryover generated within the room. Dirty air, contaminated by pollutants, relies on this dynamic balance to maintain the desired cleanliness level in the indoor environment.
Air cleanliness refers to the degree of airborne particles in a clean environment. Generally, high dust concentrations indicate low air cleanliness, while low dust concentrations indicate high cleanliness.
Cleanrooms are categorized based on the concentration of suspended particles in the air. The air cleanliness level within these controlled environments is determined by the maximum number of particles per cubic meter of air.
