Project Request
In the Oyak Dragos project, completed in 2021, the goal was to ensure a high level of thermal comfort in office areas with extensive glass facades. Although the building's main HVAC system was VRF, an additional perimeter heating solution was needed to compensate for heat losses from glass surfaces and eliminate the cold zone effect that could occur in front of the glass.
Another significant engineering challenge of the project was the air distribution in the entrance lobby, which was approximately 10.5 meters high. The diffusers to be used in this space were expected to effectively deliver warm air to the floor in heating mode and provide homogeneous air distribution without creating drafts in cooling mode.
Furthermore, due to the high number of products and a tight application schedule, managing the production and logistics process in full compliance with the construction site installation program was among the critical requirements of the project.
Solution
Within the scope of the project, over 2,400 STEKON SC110 Fanless Trench Convectors, with a total length exceeding 2 kilometers, were supplied. The convector grilles were painted in a special color to match the architectural design, ensuring aesthetic integrity with the interior space. The perimeter heating line created along the glass facade enhanced thermal comfort in front of the glass, providing an efficient heating solution that supported the VRF system.
All products were manufactured and delivered within just 8 weeks. The production and shipping process was planned to align with the contractor's installation schedule. Products were dispatched to the site in batches, while the manufacturing of the remaining products continued simultaneously as installation work progressed. This successfully supported the project timeline without any disruptions to the construction site program.
In the entrance lobby, approximately 10.5 meters high, 14 SLT VDP Swirl Diffusers were used. Thanks to their high induction performance, warm air was effectively delivered to the floor in heating mode, while homogeneous air distribution was ensured in cooling mode, preventing drafts. The diffusers were implemented in harmony with the architectural design, meeting expectations for both aesthetics and performance in the high-volume lobby area.
The project was completed flawlessly within the planned timeframe. The desired thermal comfort was successfully achieved along the glass facade, and effective air distribution was obtained in the high-ceiling lobby area, meeting both architectural expectations and mechanical system performance.
