There was a problem where hot air remained stagnant near the ceiling, while the perceived temperature in the floor-level work zones varied significantly depending on the location. In particular, due to the structural characteristics of the Gocheongo facility, the temperature gap between the upper and lower levels increased, and the perceived temperature differences between areas were further exacerbated by the layout of the equipment.
Continuous radiant heat and thermal output around CNC equipment and large machinery increased worker fatigue, creating environments where certain areas of the factory were excessively hot or stuffy.
Fine dust and stagnant air generated during the machining process remained in the workspace, leading to poor air quality. It was a site where simple cooling was insufficient, and a design capable of circulating air without stagnation was required.
We precisely adjusted the air volume and discharge direction to ensure air spreads evenly throughout the space, preventing cold or warm air from concentrating in specific areas. By directing air that was previously stagnant at the ceiling down to the working level, we reduced the temperature gap between the upper and lower sections.
We created high-reach airflow around equipment where heat is concentrated to prevent heat from lingering. Rather than simply cooling the entire space, we optimized HVAC performance to control heat specifically around the workers and the equipment environment.
To prevent dust and stagnant air generated by CNC equipment from lingering in one area, we implemented a circulation structure that ensures a continuous, uninterrupted flow of air throughout the factory. This improved not only heating and cooling but also addressed issues with stuffiness, air stagnation, and dust accumulation.
We have reduced the temperature variance between the ceiling and the floor, ensuring a more consistent heating and cooling experience anywhere in the factory. By mitigating the issue of specific zones being too hot or too cold, we have improved the consistency of the working environment.
We have reduced heat concentration around heat-generating equipment, easing the burden felt by workers. By narrowing the environmental gap between machine areas and general work zones, we have enhanced overall comfort on the factory floor.
By circulating stagnant air and reducing the time dust remains suspended, we have created a more pleasant indoor air environment. A key achievement of this project was improving not only heating and cooling performance but also ventilation and overall air quality.
