Vertical Unidirectional Flow Clean Room: A New Technology The vertical unidirectional flow clean room is a type of controlled environment that uses full ceiling air supply and lower return air systems. It typically features a covered high-efficiency filter for air distribution and a full floor grille for air return. This design creates a uniform downward airflow, ensuring a high level of cleanliness and self-cleaning capability. The layout allows for flexible placement of process equipment and simplified personal purification facilities. However, the use of a full floor grille for return air can lead to several drawbacks. The floor may appear unattractive, feel unstable underfoot, especially for women, and make it easy for small objects to fall underneath. These issues hinder the widespread adoption of this system. To address these challenges, an improved system has been developed where air is returned from the sides of the ceiling rather than the floor. This variation, known as the quasi-unidirectional flow clean room, provides better airflow patterns and reduces costs while maintaining high cleanliness levels. Studies have shown that the efficiency of high-efficiency filters and proper airflow organization are key to achieving cleanroom standards. Vertical unidirectional flow is considered the best airflow pattern, as it ensures minimal particle movement and optimal cleanliness. However, traditional systems with full ceiling air supply and floor return grilles are expensive due to the cost of the grille flooring, which can account for 30% to 50% of the total interior decoration cost. This makes them less attractive for many applications. In contrast, the side-return system offers a more cost-effective solution without compromising on performance. It ensures that most of the room, including the working area, remains in the main airflow stream, allowing for efficient cleaning with reduced air volume. This makes it ideal for various industries such as healthcare, pharmaceuticals, electronics, and precision manufacturing. The vertical unidirectional flow clean room is primarily used in environments requiring high cleanliness levels, whether for controlling non-living particles or biological contaminants. For optimal performance, the room width should be less than 6 meters. As economic development continues and cleanroom requirements become more stringent, this system is expected to see even broader application in the future.
