Case Study: Enhancing Enclosed Duct Housings with Metal Sunshade & Filtered Vent Panels 

Abstract:  This case study presents a retrofit project for enclosed duct housings using metal sunshade panels combined with filtered vent panels. The client faced heat buildup, restricted airflow, and dust infiltration, impacting equipment efficiency and maintenance cycles. By deploying modular sunshade panels and filtered vent panels, airflow was optimized, internal temperatures were reduced, and dust ingress minimized. This article details the challenges, design, fabrication, installation, results, and lessons learned, citing both internal and authoritative external references.

1. Project Background: Duct System Challenges

The client’s enclosed duct housings, designed for HVAC and industrial equipment, encountered multiple issues:

• Excessive heat accumulation from solar exposure.

• Restricted airflow through small vents, limiting ventilation effectiveness.

• High frequency of maintenance due to dust and particulate accumulation.

• Structural limitations preventing major modification to existing ducts. (Internal Panel Guide)

Jintong Perforated Metal recommended a combination of metal sunshade panels and filtered vent panels for effective heat reduction and controlled ventilation with minimal disruption. (Internal Installation Reference)

2. Why Metal Sunshade & Filtered Vent Panels Are Effective

Sunshade panels reduce solar heat gain while filtered vents maintain controlled airflow and prevent dust ingress. Kawneer confirms that sunshades improve energy efficiency and protect equipment performance. (Kawneer Article)

Filtered vent panels allow airflow without contamination. Wiremeshfabs highlights that “filtered panels maintain airflow while minimizing dust and debris entry.” (Wiremeshfabs Study)

Research indicates that sunshade and filtered vent systems can reduce heat gain by 15–30% and improve airflow efficiency by 20–35%. (MDPI Study) (Transit Tomorrow Study)

3. Design & Specification

• Material: Aluminium 6061-T6 (4 mm) for sunshade panels; stainless steel 316 (3 mm) for filtered vent panels.

• Sunshade: Horizontal projection 400 mm with powder-coat finish for UV and weather protection. (Internal Panel Design Guide)

• Filtered vent panels: Slot openings 100 mm with fine mesh filters to reduce dust entry. (Prance Building Study)

• Mounting: 60 mm ventilated gap behind panels to optimize controlled airflow. (TBK Metal Article)

• Installation: Modular clip-on panels allowing retrofit without structural modifications. (Archro Installation Guide)

4. Fabrication & Installation

Panels were fabricated under QA standards, including thickness verification, perforation accuracy, and powder-coat adhesion. Kits were shipped to site and installed by a four-person team over two days. Steps: attach sub-frame, clip-in sunshade panels, install filtered vent panels, seal joints. (QS-Wiremesh Case Study)

5. Performance Outcomes

• Internal temperatures decreased by 15 °C during peak sunlight hours.

• Passive controlled airflow improved, reducing equipment overheating.

• Maintenance intervals extended due to reduced dust ingress.

• Modernized appearance enhanced facility image. (ResearchGate Study)

6. Lessons Learned

• Sunshade sizing must match solar angles for effective shading. (SHARCHS Guide)

• Filtered vent design should balance airflow and dust protection. (Prance Building)

• Ventilated cavity behind panels is critical for passive airflow control. (TBK Metal)

• Modular clip-on panels simplify retrofit and reduce downtime. (BNP Media Study)
