普象-让好设计发光

Inspired by MuscaTese, Terracotta Valley Wind is designed to provide a passive cooling system for subway stations during the summer. By making use of the induced wind from arriving or departing subway trains, the station can be cooled down in a natural and low carbon way, eliminating the need for air-conditioning and reducing energy consumption.

Terracotta tiles, steel frames, rubber components, and floating ball valves make up the system. Rubber components help to stabilise the clay and create the water tunnel. Valves allow water in the tunnel to maintain a constant level, supplying water to the tiles continuously. Through capillary action, water passively penetrates the entire terracotta tile from the bottom. The porous nature of terracotta allows water to quickly move through the walls and evaporate, removing the heat from the surrounding environment.

When subway trains arrive and the wind passes over its surface, the tiles cool the induced wind and direct the cool air to the platform area. Meanwhile, the train’s motion propels air circulation above and below ground. The hot and humid air inside the station will be exhausted to maintain a comfortable environment. The shape of the terracotta tiles is intended to guide train-induced wind while increasing contact area with the wind. Each tile can be easily assembled and replaced.

Terracotta Valley Wind的设计受到MuscaTese的启发，用于在夏季为地铁站提供一个被动冷却系统。通过利用地铁列车到达或离开时产生的诱导风，车站可以以自然和低碳的方式降温，从而消除对空调的需求并降低能耗。

该系统由陶瓦、钢框架、橡胶部件和浮动球阀组成。橡胶部件有助于稳定粘土并形成水道。阀门使隧道中的水保持恒定水平，不断向瓷砖供水。通过毛细作用，水被动地从底部渗透到整个陶瓦。陶土的多孔性使水能够快速穿过墙壁并蒸发，从而从周围环境中带走热量。

当地铁列车到达时，风通过其表面，瓷砖冷却诱导风，并将冷空气引导至站台区域。与此同时，列车的运动推动了地面和地下的空气流通。车站内的湿热空气将被排出，以保持舒适的环境。陶瓦的形状旨在引导列车诱导的风，同时增加与风的接触面积。每片陶瓦都可进行轻松的组装和更换。
