Working principle and characteristics of laminar air supply ceiling

The working principle of a laminar air supply ceiling can be simply described as the following steps: First, the fresh air enters the fresh air section, mixes with the return air, and then enters the primary effect section. The primary effect filter filters out large particles of dust with a diameter of 10um. The air filtered by the primary filter enters the air supply channel of the air supply ceiling. Then, the high-efficiency filter further filters 0.3um-1um particles, bacteria, and other pollutants in the air. The filtered clean air flows downward evenly from the ceiling air outlet to form a vertical downward airflow, also known as laminar airflow, which delivers the clean air to the operating table in the operating room.

Laminar air supply ceiling has the following characteristics:

1. High-efficiency air purification: Through the continuous filtration of primary and high-efficiency filters, laminar air supply ceilings can effectively remove tiny particles of bacteria and other pollutants below 0.3um in the air, achieving high-quality air purification. This is particularly important in environments that require very high air quality, such as clean rooms and hospital operating rooms.

2. Uniform air supply distribution: Through the design of the air outlet and the leakage barrier purification technology, the laminar air supply ceiling can achieve uniform vertical airflow distribution and ensure consistent air quality in the entire area. This uniform airflow distribution helps control airflow, reduce dead corners and "contaminated areas", and improve air circulation.

3. Reasonable airflow speed: The airflow speed of the laminar air supply ceiling is controlled between 0.3-0.5 m/s, which can ensure sufficient ventilation while avoiding the "fan effect" that causes discomfort to people. This reasonable airflow speed helps provide a comfortable and quiet working environment.

4. Effectively isolate external pollution: The "air barrier" formed when the laminar air supply ceiling meets the ground can prevent external pollutants from entering the clean area. This isolation can effectively protect workers and equipment in the work area from external contamination and ensure a high degree of cleanliness in the working environment.

To sum up, the laminar air supply ceiling provides an effective solution for environments that require high cleanliness and air quality through efficient air filtration and leak-proof layer purification technology. Its working principle and characteristics make it widely used in various operating rooms and other fields to create a clean and comfortable surgical space environment and become one of the important purification equipment to improve the quality of the surgical environment.
