State of the Art

In the quest for sustainable and energy-efficient cooling solutions, the TerraCool project endeavors to harness the natural properties of clay through the innovative application of multi-material 3D printing technology. This research project aims to develop an advanced evaporative cooling system utilizing seashell ceramic. “TerraCool” is not only a testament to the symbiosis of traditional materials and modern technology but also a step forward in creating environmentally friendly cooling systems. The system does so through a network of water channels that would absorb rainwater and later provide evaporative cooling.

Design Drivers

The following design drivers were explored to achieve the objectives of the project: the surface morphology, the radii of the water channels and the depth of the cantilevers. A curved surface was chosen as it would provide more surface area and more time for the water to get absorbed. Some precautions were also taken in the computation process to avoid anomalies that could come up while printing.

Material Applications

Clay provides robustness and high thermal mass, and forms the core structure, providing stability and a prolonged cooling effect. In contrast, the seashell ceramic acts as the outer layer, enhancing evaporative efficiency and reflecting solar radiation. The firing temperatures for the two materials are around the same range.
