In the field of clean engineering, the selection of ventilation ducts in Shandong is a critical factor that significantly impacts system performance. The cleanliness and airtightness of these ducts are of utmost importance due to the higher wind pressure in clean air conditioning systems—often double that of standard units. This makes it even more essential to pay close attention to the design and construction of the ductwork.
The development of China’s purification air-conditioning industry began in the mid-1970s. At that time, purification was a relatively new concept, and engineers and workers placed great emphasis on the quality of ventilation ducts. The cleanliness and airtightness of the pipelines directly affect the overall efficiency of the system, influencing factors such as airflow organization, air volume, noise levels, and energy consumption.
Back then, material options were limited, and steel-zinc plates were considered advanced for use in Shandong ventilation systems, while most other systems used black steel. Despite the lack of advanced tools, workers showed strong dedication, resulting in high-quality craftsmanship, particularly in sealing joints and flanges. However, over time, some of these early systems have shown signs of wear, and issues like poor seam treatment led to significant air leakage, sometimes exceeding 50%.
This raises an important question: why do serious quality issues still persist despite technological advancements? The answer lies in the fact that many companies still rely on manual labor rather than mechanized production. While materials and machinery have improved, the skills and responsibility of workers have not always kept pace. As a result, the quality of ducts produced by hand remains inconsistent.
To address this, the industry must shift toward mechanization and standardized processes. This will ensure better quality control, reduce labor intensity, and improve the overall performance of the ducts. In recent years, the introduction of new insulation materials, such as rubber and plastic composites, has helped reduce worker fatigue. However, their high cost limits widespread adoption.
Composite ducts, including glass fiber and fiberglass reinforced ones, have also emerged as alternatives. Although they offer improvements in certain areas, they are not yet fully suitable for high-purity environments. However, the trend toward composite materials is clear, and it represents a natural evolution in the industry.
One promising option is the double-sided color plate composite duct. This type of duct combines the benefits of color steel panels with a core made from flame-retardant polystyrene, polyurethane, or fiberglass. It offers excellent rigidity, smooth surfaces, and superior airtightness. Its production can be fully mechanized, ensuring consistency and reducing costs.
Moreover, the use of PVC closed groove flanges enhances the airtightness of connections, and the card-type connection system simplifies installation, especially in tight spaces. These features make composite ducts ideal for clean engineering applications where precision and hygiene are crucial.
In conclusion, the future of ventilation ducts in Shandong’s purification air conditioning systems lies in the adoption of advanced composite materials and automated production methods. By embracing these innovations, the industry can achieve greater efficiency, reliability, and sustainability.
